The relative size and depiction of these elements may be exaggerated for clarity, illustration, and convenience. 
     DETAILED DESCRIPTION 
     Reference will now be made in detail to embodiments of the present disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, when a detailed description of well-known functions or configurations related to this document is determined to unnecessarily cloud a gist of the inventive concept, the detailed description thereof will be omitted. The progression of processing steps and/or operations described is an example; however, the sequence of steps and/or operations is not limited to that set forth herein and may be changed as is known in the art, with the exception of steps and/or operations necessarily occurring in a particular order. Like reference numerals designate like elements throughout. Names of the respective elements used in the following explanations are selected only for convenience of writing the specification and may be thus different from those used in actual products. 
     Advantages and features of the present disclosure, and implementation methods thereof will be clarified through following embodiments described with reference to the accompanying drawings. The present disclosure may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Further, the present disclosure is only defined by scopes of claims. 
     A shape, a size, a ratio, an angle, and a number disclosed in the drawings for describing embodiments of the present disclosure are merely an example, and thus, the present disclosure is not limited to the illustrated details. Like reference numerals refer to like elements throughout. In the following description, when the detailed description of the relevant known function or configuration is determined to unnecessarily obscure the important point of the present disclosure, the detailed description will be omitted. 
     In a case where “comprise,” “have,” and “include” described in the present specification are used, another part may be added unless “only” is used. The terms of a singular form may include plural forms unless referred to the contrary. 
     In construing an element, the element is construed as including an error or tolerance range although there is no explicit description of such an error or tolerance range. 
     In describing a position relationship, for example, when a position relation between two parts is described as “on,” “over,” “under,” and “next,” one or more other parts may be disposed between the two parts unless a more limiting term, such as “just” or “direct(ly)” is used. 
     In describing a time relationship, for example, when the temporal order is described as, for example, “after,” “subsequent,” “next,” and “before,” a case which is not continuous may be included unless a more limiting term, such as “just,” “immediate(ly),” or “direct(ly)” is used. 
     It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present disclosure. 
     In describing the elements of the present disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify the corresponding elements from the other elements, and basis, order, or number of the corresponding elements should not be limited by these terms. The expression that an element is “connected,” “coupled,” or “adhered” to another element or layer, the element or layer can not only be directly connected or adhered to another element or layer, but also be indirectly connected or adhered to another element or layer with one or more intervening elements or layers “disposed” between the elements or layers, unless otherwise specified. 
     The term “at least one” should be understood as including any and all combinations of one or more among the associated listed elements. For example, the meaning of “at least one or more of a first element, a second element, and a third element” denotes the combination of all elements proposed from two or more of the first element, the second element, and the third element as well as the first element, the second element, or the third element. 
     In the description of embodiments, when a structure is described as being positioned “on or above” or “under or below” another structure, this description should be construed as including a case in which the structures contact each other as well as a case in which a third structure is disposed therebetween. The size and thickness of each element shown in the drawings are given merely for the convenience of description, and embodiments of the present disclosure are not limited thereto, unless otherwise specified. 
     Features of various embodiments of the present disclosure may be partially or overall coupled to or combined with each other, and may be variously inter-operated with each other and driven technically as those skilled in the art can sufficiently understand. The embodiments of the present disclosure may be carried out independently from each other, or may be carried out together in co-dependent relationship. 
     In the present disclosure, examples of a display apparatus may include a narrow-sense display apparatus such as an organic light emitting display (OLED) module or a liquid crystal module (LCM) including a display panel and a driver for driving the display panel. Also, examples of the display apparatus may include a set device (or a set apparatus) or a set electronic device such as a notebook computer, a TV, a computer monitor, an equipment apparatus including an automotive apparatus or another type apparatus for vehicles, or a mobile electronic device such as a smartphone or an electronic pad, which is a complete product (or a final product) including an LCM or an OLED module. 
     Therefore, in the present disclosure, examples of the display apparatus may include a narrow-sense display apparatus itself, such as an LCM or an OLED module, and a set apparatus which is a final consumer device or an application product including the LCM or the OLED module. 
     In some embodiments, an LCM or an OLED module including a display panel and a driver may be referred to as a narrow-sense display apparatus, and an electronic apparatus which is a final product including an LCM or an OLED module may be referred to as a set apparatus. For example, the narrow-sense display apparatus may include a display panel, such as an LCD or an OLED, and a source printed circuit board (PCB) which is a controller for driving the display panel. The set device may further include a set PCB which is a set controller electrically connected to the source PCB to overall control the set apparatus. 
     A display panel applied to an embodiment of the present disclosure may use all types of display panels such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, and an electroluminescent display panel, but embodiments are not limited to a specific display panel which is vibrated by a vibration device according to an embodiment of the present disclosure to output a sound. Also, a shape or a size of a display panel applied to a display apparatus according to an embodiment of the present disclosure is not limited. 
     For example, if the display panel is the liquid crystal display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels respectively provided at a plurality of pixel areas defined by intersections of the gate lines and the data lines. Also, the display panel may include an array substrate including a thin film transistor (TFT) which is a switching element for adjusting a light transmittance of the plurality of pixels, an upper substrate including a color filter and/or a black matrix, and a liquid crystal layer between the array substrate and the upper substrate. 
     Moreover, if the display panel is the organic light emitting display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels respectively provided at a plurality of pixel areas by intersections of the gate lines and the data lines. Also, the display panel may include an array substrate including a TFT which is an element for selectively applying a voltage to the pixels, an organic light emitting device layer on the array substrate, and an encapsulation substrate disposed on the array substrate to cover the organic light emitting device layer. The encapsulation substrate may protect the TFT and the organic light emitting device layer from an external impact and may prevent water or oxygen from penetrating into the organic light emitting device layer. Also, a layer provided on the array substrate may include an inorganic light emitting layer (for example, a nano-sized material layer, a quantum dot, or the like). As another embodiment, the layer provided on the array substrate may include a micro light emitting diode. 
     The display panel may further include a backing such as a metal plate attached on the display panel. However, embodiments are not limited to the metal plate, and the display panel may include another structure. 
     In the present disclosure, the display apparatus including a vibration device may be applied to vehicles as a user interface module such as a central control panel for automobiles. For example, the display panel may be provided between occupants sitting on two front seats in order for a vibration of the display panel to be transferred to the inside of a vehicle. Therefore, an audio experience in a vehicle is improved in comparison with a case where speakers are disposed on interior sides of the vehicle. 
     Features of various embodiments of the present disclosure may be partially or overall coupled to or combined with each other, and may be variously inter-operated with each other and driven technically as those skilled in the art can sufficiently understand. The embodiments of the present disclosure may be carried out independently from each other, or may be carried out together in co-dependent relationship. 
     Hereinafter, a display apparatus according to the present disclosure will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Since a scale of each of elements shown in the accompanying drawings is different from an actual scale for convenience of description, the present disclosure is not limited to the shown scale.

     An encapsulation part may be formed on the substrate to surround the pixel array part, and thus, may prevent oxygen or water (or moisture) from penetrating into the light emitting layer of the pixel array part. The encapsulation part according to an embodiment of the present disclosure may be formed in a multi-layer structure where an organic material layer and an inorganic material layer are alternately stacked, but embodiments of the present disclosure are not limited thereto. The inorganic material layer may prevent oxygen or water (or moisture) from penetrating into the light emitting layer of the pixel array part. The organic material layer may be formed to have a thickness which is relatively thicker than the inorganic material layer, so as to cover particles occurring in a manufacturing process. For example, the encapsulation part may include a first inorganic layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer.

     The lower substrate may be a second substrate or a color filter array substrate and may include a pixel pattern, including an opening area overlapping with the pixel area formed in the upper substrate, and a color filter layer formed at the opening area. The lower substrate may have a size which is smaller than the upper substrate, but embodiments of the present disclosure are not limited thereto. For example, the lower substrate may overlap a portion, other than the first edge (or first periphery), of the upper substrate. The lower substrate may be attached to a portion, other than the first edge, of the upper substrate with a liquid crystal layer therebetween using a sealant. 
     The liquid crystal layer may be interposed between the upper substrate and the lower substrate and may include a liquid crystal including liquid crystal molecules where an alignment direction thereof is changed based on an electric field generated by the common voltage and a data voltage applied to a pixel electrode for each pixel.

For example, an edge or a corner of the first supporting member  310  may have an inclined shape or a curved shape through a chamfer process or a corner rounding process. 
     According to some embodiments of the present disclosure, the first supporting member  310  may include a glass material, a metal material, or a plastic material.

     The display apparatus according to an embodiment of the present disclosure may further include a middle frame  700 . 
     The middle frame  700  may be disposed between a rear edge (or a rear periphery) of the display device  100  and a front edge (or a front periphery) of the supporting member  300 . The middle frame  700  may support an edge of (or a periphery) each of the display device  100  and the supporting member  300 . The middle frame  700  may surround at least one or more of side surfaces among each of the display device  100  and the supporting member  300 . The middle frame  700  may provide a gap space GS between the display device  100  and the supporting member  300 . The gap space GS may be referred to as an air gap, a vibration space, or a vibration device disposition space, but embodiments of the present disclosure are not limited thereto. 
     According to some embodiments of the present disclosure, the middle frame  700  may include a metal material or a plastic material. For example, the middle frame  700  may be formed of a metal material, for improving a side appearance design of the display apparatus and protecting side surfaces of the display apparatus. 
     According to some embodiments of the present disclosure, the middle frame  700  may be connected or coupled to a rear edge (or a rear periphery) of the display device  100  by a third adhesive member  707 . The middle frame  700  may be connected or coupled to a front edge (or a front periphery) of the supporting member  300  by a fourth adhesive member  708 . A front surface of the supporting member  300  may be referred to as the other surface, a second surface, or an upper surface, but embodiments of the present disclosure are not limited thereto. Also, the middle frame  700  may be referred to as a middle cabinet, a middle cover, or a middle chassis, but embodiments of the present disclosure are not limited thereto. Or, the middle frame  700  may be integrally formed with the second supporting member  350 , and may be referred to as a second supporting member  350 . 
     The middle frame  700  according to some embodiments of the present disclosure may include a supporting portion  710  and a sidewall portion  730 . The supporting portion  710  may be a first portion, and the sidewall portion  730  may be a second portion, but embodiments of the present disclosure are not limited thereto. 
     According to some embodiments of the present disclosure, the supporting portion  710  may have a single tetragonal (e.g., quadrilateral) picture frame structure, but embodiments of the present disclosure are not limited thereto. For example, the supporting portion  710  may be between the rear edge of the display device  100  and the front edge of the supporting member  300  to have a plurality of division bar shapes. 
     The supporting portion  710  may be disposed between the rear edge (or the rear periphery) of the display device  100  and the front edge (or the front periphery) of the supporting member  300 , and thus, may provide a gap space GS between the display device  100  and the supporting member  300 . A front surface of the supporting portion  710  may be coupled to the rear edge of the display device  100  by the third adhesive member  707 , and a rear surface of the supporting portion  710  may be coupled or connected to the front edge of the supporting member  300  by the fourth adhesive member  708 . The supporting portion  710  may have a thickness (or height) corresponding to a total thickness of the vibration device  500 . For example, a thickness of the supporting portion  710  may be adjusted based on a thickness of the vibration device  500  between the display device  100  and the supporting member  300 , a thickness of the third adhesive member  707 , and a thickness of the fourth adhesive member  708 . 
     The third adhesive member  707  may be between the rear edge of the display device  100  and a front surface of the supporting portion  710 . For example, the third adhesive member  707  may be an adhesive resin, a double-sided tape, or a double-sided adhesive foam pad, but embodiments of the present disclosure are not limited thereto. 
     The fourth adhesive member  708  may be between the front edge of the supporting member  300  and a rear surface of the supporting portion  710 . For example, the fourth adhesive member  708  may be an adhesive resin, a double-sided tape, or a double-sided adhesive foam pad, but embodiments of the present disclosure are not limited thereto. The fourth adhesive member  708  may be formed of a material differing from the third adhesive member  707 . 
     The sidewall portion  730  may be vertically coupled to an outer surface of the supporting portion  710  in parallel with a thickness direction Z of the display apparatus. The sidewall portion  730  may surround all of an outer surface (or an outer sidewall) of the display device  100  and an outer surface (or an outer sidewall) of the supporting member  300 , thereby protecting the outer surface of each of the display device  100  and the supporting member  300  and improving an appearance design of a side surface of the display apparatus. The middle frame  700  according to some embodiments of the present disclosure may be coupled or connected to each other such that the supporting portion  710  and sidewall portion  730  form a single body, and thus, may have a picture frame structure having “├”-shaped cross-sectional surface. 
     The display apparatus according to an embodiment of the present disclosure may include an adhesive member instead of the middle frame  700 . 
     The adhesive member may be between the rear edge of the display device  100  and the front edge of the supporting member  300  and may provide the gap space GS between the display device  100  and the supporting member  300 . The adhesive member may have a thickness (or a height) corresponding to a total thickness of the vibration device  500 . For example, a thickness of the adhesive member may be adjusted based on the thickness of the vibration device  500  between the display device  100  and the supporting member  300 . The adhesive member may perform the same function as that of the supporting portion  710  of the middle frame  700 . 
     When the display apparatus includes the adhesive member instead of the middle frame  700 , the supporting member  300  may include a sidewall cover portion which surrounds all of an outer surface (or an outer sidewall) of the display device  100 , an outer surface (or an outer sidewall) of the supporting member  300 , and an outer surface (or an outer sidewall) of the adhesive member. 
     The sidewall cover portion may extend from an end of the second supporting member  350  and may be vertically bent to be parallel to a thickness direction Z of the display apparatus. According to some embodiments of the present disclosure, the sidewall cover portion may have a single sidewall structure or a hemming structure. The hemming structure may denote a structure where ends of an arbitrary member is bent in a curved shape to overlap each other, or are spaced apart from each other in parallel. For example, the sidewall cover portion having the hemming structure may include a first sidewall, which extends from the end of the second supporting member  350  and is vertically bent to be parallel to the thickness direction Z of the display apparatus, and a second sidewall which extends from an end of a first sidewall and is bent to be parallel to the first sidewall. The second sidewall may be between the outer surface of the display device  100  and the first sidewall. For example, the second sidewall may not be exposed at an outermost side surface of the display apparatus and may be covered by the first sidewall, thereby improving a side appearance design of the display apparatus. 
     Therefore, the display apparatus according to an embodiment of the present disclosure may output a sound PVS to the forward direction FD based on a vibration of the display device  100  (for example, the display panel  110 ) caused by a vibration of the one or more vibration device  500  disposed between the display device  100  and the supporting member  300 , thereby enhancing an immersion experience of a viewer watching an image displayed by the display apparatus. 
     Moreover, in the display apparatus according to an embodiment of the present disclosure, since a sound PVS is generated based on a vibration of the display device  100  (for example, the display panel  110 ), a separate speaker may not be provided, thereby enhancing a design of a set apparatus and a degree of freedom in disposition of elements. 
       FIGS.  3 A to  3 C  illustrate a vibration device according to an embodiment of the present disclosure. 
     With reference to  FIGS.  3 A to  3 C , one or more vibration device  500  may include a bobbin  1650  disposed around a magnet  1620 , and a coil  1660  disposed around the bobbin  1650 . 
     For example, the magnet  1620  may be disposed on the first plate  1610 . The magnet  1620  may use a sintered magnet of barium ferrite, and the magnet  1620  may be formed of iron (III) oxide (Fe 2 O 3 ), barium carbonate (BaCO 3 ; “witherite”), neodymium (Nd) magnet, strontium ferrite (Fe 12 O 19 Sr) with improved magnetic component, an alloy cast magnet including aluminum (Al), nickel (Ni), and cobalt (Co), and/or the like. As another embodiment, the neodymium magnet may be neodymium-iron-boron (Nd—Fe—B). However, embodiments of the present disclosure are not limited to these materials or examples. 
     A center pole  1630  may be disposed on the magnet  1620 . The center pole  1630  may be referred to as pole pieces. As another embodiment of the present disclosure, pole pieces may be further disposed on the center pole  1630 . 
     The bobbin  1650  may surround around the magnet  1620 . For example, the bobbin  1650  may be disposed on the first plate  1610 . The bobbin  1650  may have a circular shape or an oval shape, but embodiments of the present disclosure are not limited thereto. The oval shape may have an elliptical shape, a rectangular shape with rounded corners, or non-circular curved shape having a width different from its height, but the present embodiment is not limited thereto. For example, in the bobbin  1650  having the oval shape, a ratio of a long-axis diameter to a short-axis diameter may be configured to 1.3:1 to 2:1. The bobbin  1650  having the oval shape may more improve a sound of a high-pitched sound band than a circular shape and may decrease the occurrence of heat caused by a vibration, and thus, may have an excellent heat dissipation characteristic. 
     The coil  1660  according to some embodiments of the present disclosure may be wound to surround an outer circumference surface of the bobbin  1650  and may be supplied with a sound-generating current (or a voice current) from the outside. The coil  1660  may be lowered or raised along with the bobbin  1650 . The coil  1660  may be referred to as a voice coil. When a current is applied to the coil  1660 , a whole portion of the bobbin  1650  may move upward and downward according to Fleming&#39;s left hand rule based on an application magnetic field generated around the coil  1660  and an external magnetic field generated around the magnet  1620 , and a sound PVS or a sound wave may be generated based on a vibration of the display device  100  caused by a vertical movement (or vibration) of the bobbin  1650 . 
     The bobbin  1650  according to some embodiments of the present disclosure may be disposed on the first plate  1610  to surround around the magnet  1620 . According to an embodiment of the present disclosure, as the coil  1660  is wound to surround an outer circumference surface of the bobbin  1650 , heat occurring in the coil  1660  may be transferred to the bobbin  1650 , and the coil  1660  may include a material which is relatively good in heat dissipation characteristic, for decreasing an image quality defect affecting the display panel  110  due to the heat of the bobbin  1650 . 
     Because the bobbin  1650  according to some embodiments of the present disclosure vibrates upward and downward, an eccentric vibration (or a horizontal vibration) may occur due to a vertical vibration, and an eccentric vibration of the bobbin  1650  may be affected by a weight of the bobbin  1650 . A weight of the bobbin  1650  may be affected by a weight of the coil  1660 . Therefore, when a weight of the coil  1660  is reduced, the eccentric vibration of the bobbin  1650  may decrease. Therefore, considering heat transferred to the bobbin  1650  and the eccentric vibration of the bobbin  1650 , the coil  1660  may have a relatively good heat dissipation characteristic because thermal conductivity thereof is better than copper which is a material of a general coil, and may include an aluminum (Al) material which has a relatively good heat dissipation characteristic and is relatively lightweight compared to copper. 
     Moreover, in aluminum, since oxide is formed in air, welding may not be easy in manufacturing the vibration device  500 , and thus, the coil  1660  according to an embodiment of the present disclosure may include an aluminum (Al) layer (or a first metal layer) for dissipating heat and a metal covering layer (or a second metal layer) surrounding the Al layer. The metal covering layer may include one of copper (Cu), silver (Ag), and gold (Au). For example, the coil  1660  may be a copper clad aluminum wire which copper covers. The metal covering layer may be formed as a thin film type outside the first metal layer, and thus, may not greatly affect an increase in weight of the coil  1660 . Therefore, a weight of the coil  1660  according to an embodiment of the present disclosure may decrease by about 60% compared to a coil including only Cu or a Cu wire. 
     According to some embodiments of the present disclosure, the bobbin  1650  may include a structure including a material obtained by processing pulp or paper, aluminum (Al) or magnesium (Mg) or an alloy thereof, or synthetic resin such as polyimide. For example, the bobbin  1650  may be implemented with a polyimide film which is relatively good in heat dissipation characteristic and is relatively lightweight, for preventing an image quality defect of the display panel  110  caused by heat occurring in the coil  1660 . 
     The polyimide film may have physical properties which are not changed within a wide temperature range from −273° C. to 400° C. and may have a heat resistance, electrical insulation, flexibility, and nonflammable. Also, since the polyimide film is good in thermal and mechanical strength, the polyimide film may enhance the reliability of the bobbin  1650 , and the occurrence of heat caused by a vibration of the bobbin  1650  may be reduced based on an excellent heat dissipation characteristic. For example, the polyimide film may be KAPTON and may be a condensation of pyromellitec dianhydride and 4,4′-oxydianiline, but embodiments of the present disclosure are not limited thereto. 
     The center pole  1630  may be accommodated or inserted into the bobbin  1650  and may guide raising or lowering of the bobbin  1650 . For example, since the center pole  1630  is accommodated or inserted into the bobbin  1650 , an outer circumference surface of the center pole  1630  may be surrounded by the bobbin  1650 . The center pole  1630  may be referred to as an elevation guider or pole pieces, but embodiments of the present disclosure are not limited thereto. 
     A second plate  1610 ′ may be disposed on the first plate  1610 . The second plate  1610 ′ may be yoke, but embodiments of the present disclosure are not limited thereto. One or more among the first plate  1610  and the second plate  160 ′ may be formed of a magnetic material such as iron (Fe), but embodiments of the present disclosure are not limited thereto. 
     A frame  1640  may be disposed at outside around the second plate  1610 ′. The damper  1670  may be disposed between the frame  1640  and the bobbin  1650 . The frame  1640  according to some embodiments of the present disclosure may be provided at the front edge of the second plate  1610 ′ to have a certain height and the same shape as that of the bobbin  1650 . According to another embodiment of the present disclosure, the frame  1640  may include a hollow portion that is provided at the front edge of the second plate  1610 ′ to have a certain height and the same shape as that of the bobbin  1650 . 
     The damper  1670  may be connected between the frame  1640  and the vibration device. For example, the damper  1650  may be connected between the frame  1640  and the bobbin  1650 . The damper  1670  may be referred to as a spider, a suspension, or an edge, but embodiments of the present disclosure are not limited thereto. 
     One end or one portion of the damper  1670  according to some embodiments of the present disclosure may be connected to the frame  1640 , and the other end or the other portion of the damper  1670  may be connected to an upper outer surface of the bobbin  1650 . The damper  1670  may have a creased structure between the one end and the other end thereof and may be contracted and relaxed based on a vertical motion of the bobbin  1650  to control a vibration of the bobbin  1650 . The damper  1670  may be connected between the bobbin  1650  and the frame  1640  and may limit a vibration distance of the bobbin  1650  with a restoring force. For example, when the bobbin  1650  vibrates by a certain distance or more or vibrates by a certain distance or less, the bobbin  1650  may be restored to an original position by the restoring force of the damper  1670 . 
     The one or more vibration device  500  according to some embodiments of the present disclosure may further include a bobbin ring  1652 . 
     The bobbin ring  1652  may be disposed at a front surface (or a front end portion) of the bobbin  1650 . The bobbin ring  1652  may transfer a rising and lowering motion (or vibration) of the bobbin  1650  to the rear surface of the display device  100 . The bobbin ring  1652  according to some embodiments of the present disclosure may have a ring shape disposed at the front surface of the bobbin  1650 , a disc shape (or a circular plate shape) covering the whole front surface of the bobbin  1650 , or a cap shape surrounding the front surface and the upper outer surface of the bobbin  1650 , but the shapes are not limited thereto. For example, the bobbin ring  1652  may be referred to as a bobbin protection member, but embodiments of the present disclosure are not limited thereto. 
     In the display apparatus according to an embodiment of the present disclosure, the display device  100  may further include a heat dissipation member  102 . 
     The heat dissipation member  102  may be disposed at a rear surface of the display device  100 . For example, the heat dissipation member  102  may be disposed between the one or more vibration device  500  and the display device  100 . The heat dissipation member  102  according to an embodiment of the present disclosure may be attached at a rear surface of the display device  100  to overlap the vibration device  500 . A first adhesive member  401  may be disposed between the heat dissipation member  102  and the display device  100 . For example, the first adhesive member  401  may be disposed between the heat dissipation member  102  and the display panel  110 . For example, the heat dissipation member  102  may be attached at the display panel  110  by the first adhesive member  401 . For example, the heat dissipation member  102  may be attached at a rear surface of the display panel  110  by the first adhesive member  401 . The first adhesive member  401  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. A second adhesive member  403  may be disposed between the heat dissipation member  102  and the vibration device  500 . For example, the heat dissipation member  102  may be attached on the vibration device  500  by the second adhesive member  403 . For example, the second adhesive member  403  may be disposed between the heat dissipation member  102  and the bobbin ring  1652 . The heat dissipation member  102  may be attached to the bobbin ring  1652  by the second adhesive member  403 . The second adhesive member  403  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. As illustrated in  FIGS.  3 A to  3 C , the second adhesive member  403  may be formed at a portion with the heat dissipation member  102  attached thereon. However, the present disclosure is not limited thereto, the second adhesive member  403  may be formed at a whole rear surface of the heat dissipation member  102  or the display panel  110 . For example, the second adhesive member  403  may be formed at a whole surface between the rear surface of the heat dissipation member  102  and the vibration device  500 , or a whole surface between the rear surface of the display panel  110  and the vibration device  500 . For example, the second adhesive member  403  may be formed at a whole surface between the rear surface of the heat dissipation member  102  and the bobbin ring  1652 , or a whole surface between the rear surface of the display panel  110  and the bobbin ring  1652 . 
     Because the heat dissipation member  102  is disposed at the rear surface of the display device  100  to overlap the vibration device  500 , heat occurring in driving of the vibration device  500  may be diffused toward the display device  100 , thereby preventing the performance of the vibration device  500  from being reduced by heat. Also, with respect to a center portion of the vibration device  500 , the heat dissipation member  102  may have a size which is relatively greater than or equal to the vibration device  500 , and thus, heat occurring in driving of the vibration device  500  may be diffused to a wide region, thereby preventing heat from being intensively transferred to a local region of the display device  100  overlapping the vibration device  500 . Accordingly, the local non-uniform luminance of the display device  100  may be prevented or minimized. 
     According to some embodiments of the present disclosure, the heat dissipation member  102  may include a metal material having high heat conductivity, and for example, may include one material of aluminum (Al), copper (Cu), silver (Ag), and magnesium (Mg) or an alloy thereof, but embodiments of the present disclosure are not limited thereto. The heat dissipation member  102  may be referred to as the other term such as a heat diffusion member, a heat diffusion sheet, a heat diffusion layer, a heat diffusion plate, a heat sink, a heat dissipation sheet, or a heat dissipation plate, but embodiments of the present disclosure are not limited thereto. 
     With reference to  FIG.  3 A , the one or more vibration device  500  may further include a diameter enlargement portion  1614 . For example, the diameter enlargement portion  1614  and the first plate  1610  may be provided as one body. For example, the diameter enlargement portion  1614  may be integrally formed with the first plate  1610 . The first plate  1610  of the vibration device  500  may not have a cylindrical or cylinder shape. One side of the first plate  1610  may include a protrusion portion having a diameter which is greater than the other portion of the first plate  1610 . A protrusion portion region where a diameter thereof is enlarged may be referred to as the diameter enlargement portion  1614 . The diameter enlargement portion  1614  may have a ring shape. An extension portion  1612  for the arrangement of the vibration device  500  may be formed at a portion of the diameter enlargement portion  1614 . 
     A fourth connection member  333  may be disposed at the extension portion  1612 . The fourth connection member  333  may include a screw  1720  and a nut  1730 . For example, the nut  1730  may be disposed in the supporting member  300 . The one or more vibration device  500  may be coupled to the second supporting member  350  by the nut  1730  and the screw  1720 . Accordingly, the vibration device  500  may be accommodated into a supporting hole  350 S which is provided at the second supporting member  350 . 
     The nut  1730  may be, for example, a self-clinching nut. An example of the self-clinching nut may include PEM® nut, but embodiments of the present disclosure are not limited thereto. When the self-clinching nut is used, a vibration generated by the vibration device  500  may be absorbed by a portion of the self-clinching nut which is the nut  1730 , and thus, a vibration transferred to the supporting member  300  may be reduced. 
     In  FIGS.  3 A to  3 C , an example where the supporting member  300  includes the first supporting member  310  and the second supporting member  350  is described, but embodiments of the present disclosure are not limited thereto. For example, the supporting member  300  may include only the second supporting member  350 . 
       FIG.  3 B  illustrates a vibration device having a thickness which is smaller than the vibration device of  FIG.  3 A . 
     With reference to  FIG.  3 B , a fourth connection member  333  may be disposed at a vibration device  500  so as to place the vibration device  500  inside (or an inner space) of the display apparatus. A first plate  1610  may include an extension portion  1612 . The fourth connection member  333  may be disposed at the extension portion  1612  of the first plate  1610 . For example, a screw tap may be formed by enlarging a thickness of the first plate  1610 , and then, screwing may be performed. Examples of the screw tap may include a manual tap, a machine tap, a gas tap, and a master tap, but embodiments of the present disclosure are not limited thereto. For example, the fourth connection member  333  may be disposed in the supporting member  300 . For example, the fourth connection member  333  may be disposed in a first supporting member  310 . The fourth connection member  333  may include a screw  1720  and a nut  1730 . The screw  1720  and the nut  1730  may be disposed in the supporting member  300 , and the vibration device  500  may be disposed in the supporting member  300  by the screw  1720  and the nut  1730 . For example, the nut  1730  may be a self-clinching nut. An example of the self-clinching nut may include PEM® nut, but embodiments of the present disclosure are not limited thereto. 
     The vibration device  500  may be coupled to the supporting member  300  by the nut  1730  by a press-fit scheme (or an indentation method) without a supporting hole of the supporting member  300  (for example, a second supporting member  350 ). The press-fit scheme may use a saw-toothed press-fit scheme, but an embodiment of the present disclosure is not limited to a coupling scheme or shape. Therefore, the vibration device  500  may be disposed inside of the display apparatus. For example, the vibration device  500  may be disposed between the display panel  110  and the supporting member  300  by the fourth connection member  333 . 
     Therefore, a vibration device may be disposed inside of the display apparatus, and thus, a supporting hole of a supporting member may not be provided, thereby preventing the penetration of particles from the outside through the supporting hole of the supporting member. Also, the vibration device may not be exposed at a rear surface of the supporting member, and thus, a display apparatus having a sense of beauty in external appearance may be provided, thereby preventing the damage of the vibration device. Also, the vibration device may be disposed inside of the display apparatus, and thus, a sound of a low-pitched sound band of the vibration device may be more enhanced. 
     With reference to  FIG.  3 C , a fourth connection member  333  may be disposed in a vibration device  500  so as to place the vibration device  500  inside of the display apparatus. A frame  1640  may include an extension portion  1642 . The fourth connection member  333  may be disposed at the extension portion  1642  of the frame  1640 . The fourth connection member  333  may include a screw  1720  and a nut  1730 . The screw  1720  and the nut  1730  may be disposed in the supporting member  300 , and the vibration device  500  may be disposed at the supporting member  300  by the screw  1720  and the nut  1730 . For example, the nut  1730  may be a self-clinching nut. An example of the self-clinching nut may include PEM® nut, but embodiments of the present disclosure are not limited thereto. 
     For example, the vibration device  500  may be coupled to the supporting member  300  by the nut  1730  by the press-fit scheme (or the indentation method) without a supporting hole of the supporting member  300 . The press-fit scheme may use a saw-toothed press-fit scheme, but an embodiment of the present disclosure is not limited to a coupling scheme or shape. Therefore, the vibration device  500  may be disposed inside of the display apparatus. For example, the vibration device  500  may be disposed between the display panel  110  and the supporting member  300  by the fourth connection member  333 . Therefore, a vibration device may be disposed inside of the display apparatus, and thus, a supporting hole of a supporting member may not be provided, thereby preventing the penetration of particles from the outside through the supporting hole of the supporting member. Also, the vibration device may not be exposed at a rear surface of the supporting member, and thus, a display apparatus having an aesthetic sensibility in external appearance may be provided, thereby preventing the damage of the vibration device. Also, the vibration device may be disposed inside of the display apparatus, and thus, a sound of the low-pitched sound band of the vibration device may be more enhanced. 
       FIG.  4    is another cross-sectional view taken along line I-I′ illustrated in  FIG.  1   . 
     With reference to  FIGS.  1  and  4   , a display apparatus according to an embodiment of the present disclosure may include a display device  100 , a supporting member  300 , and one or more vibration device  500 . Descriptions of the display device  100 , the display panel  110 , the supporting member  300 , and a middle frame  700  are the same as descriptions given above with reference to  FIGS.  1  and  2   , and thus, repetitive descriptions of elements other than a partition and elements relevant thereto may be omitted or will be briefly given. 
     The one or more vibration device  500  according to an embodiment of the present disclosure may be disposed at a structure  510  disposed at the supporting member  300 . The one or more vibration device  500  disposed at the structure  510  to vibrate the display device  100  may be a single-body structure or a single structure which is modularized as one element (or one component). For example, the structure  510  and the one or more vibration device  500  may be manufactured as a finished product such as a single-body structure or a single structure by a modularization process (or an assembly process) instead of an assembly process performed on a display apparatus. After the structure  510  and the one or more vibration device  500  are manufactured as a finished product, a gap space GS between the display device  100  and the supporting member  300  may be mounted or disposed by a relatively simple element (or component) mounting (or placing) process in an assembly process performed on a display apparatus. Accordingly, in a display apparatus according to an embodiment of the present disclosure, the assembly of the one or more vibration device  500  may be improved in a process of assembling modules, thereby enhancing a production yield rate. 
     According to some embodiments of the present disclosure, the first supporting member  310  and the second supporting member  350  may be coupled or connected to each other by a connection member  330 . For example, the connection member  330  may be an adhesive resin, a double-sided tape, or a double-sided adhesive foam pad. The connection member  330  may have elasticity for absorbing an impact. 
     According to some embodiments of the present disclosure, the connection member  330  may be disposed at a whole region between the first supporting member  310  and the second supporting member  350 . 
     According to some embodiments of the present disclosure, the connection member  330  may be provided in a mesh structure including an air gap between the first supporting member  310  and the second supporting member  350 . For example, a portion of the air gap between the first supporting member  310  and the second supporting member  350  may be used as a disposition region of a signal transfer member or a cable connected to the vibration device  500 . 
     The one or more vibration device  500  may generate a sound PVS using the display device  100  as a vibration plate. For example, the one or more vibration device  500  may generate a sound PVS using the display panel  110  as a vibration plate. 
     The display apparatus according to some embodiments of the present disclosure may include one or more vibration device  500  which is disposed at a rear center portion (or center region) of the display device  100 . For example, the one or more vibration device  500  may vibrate the rear center portion of the display device  100  to generate the sound PVS to the forward direction (FD) of the display device  100  based on a vibration of the display device  100 . 
     According to another embodiment of the present disclosure, the display apparatus may include a first vibration device  500 - 1  disposed at a first region (or a left region) of the display device  100  and a second vibration device  500 - 2  disposed at a second region (or a right region) of the display device  100 , with respect to the rear center portion of the display device  100 . For example, the first vibration device  500 - 1  may vibrate a first rear region of the display device  100  to generate a sound PVS based on a vibration of the first region of the display device  100 . The second vibration device  500 - 2  may vibrate a second rear region of the display device  100  to generate a sound PVS based on a vibration of the second region of the display device  100 . The display apparatus according to another embodiment of the present disclosure may output a two-channel sound based on left-right sound separation by the first and second vibration devices  500 - 1  and  500 - 2 . For example, the first vibration device  500 - 1  may be configured to output a left sound, and the second vibration device  500 - 2  may be configured to output a right sound. 
     According to some embodiments of the present disclosure, the one or more vibration device  500  may be between the display device  100  and the supporting member  300  and may vibrate the display device  100  to generate a sound PVS. A rear surface of the one or more vibration device  500  may be covered by the supporting member  300 , and thus, may be concealed without being directly exposed at an outermost rear surface of the display apparatus. Therefore, since the rear surface of the at least one vibration device  500  is covered by the supporting member  300 , the display apparatus according to an embodiment of the present disclosure may have a clean back design where a rear surface or a portion of the at least one vibration device  500  is not exposed or is not seen by eyes of a user, thereby improving a rear appearance design. 
     According to some embodiments of the present disclosure, the structure  510  disposed at the supporting member  300  and the one or more vibration device  500  disposed at the structure  510  to vibrate the display device  100  may be a single-body structure or a single structure which is modularized as one element (or one component). For example, the one or more the vibration device  500  may be manufactured as a finished-product type such as a single-body structure or a single structure through a modularization process (or an assembly process) instead of an assembly process performed on the display apparatus, and then, the at least one vibration device  500  may be mounted or disposed in a gap space GS between the display device  100  and the supporting member  300  through a relatively simple element (or component) mounting (or placing) process in the assembly process performed on the display apparatus. Accordingly, in the display apparatus according to an embodiment of the present disclosure, the assembly of the one or more vibration device  500  may be improved in a process of assembling modules, thereby enhancing a production yield rate. 
     The one or more vibration device  500  according to an embodiment of the present disclosure may directly or indirectly vibrate the display device  100 . For example, the one or more vibration device  500  may be directly connected to the display panel  110  and may directly vibrate the display panel  110 . As another embodiment of the present disclosure, the one or more vibration device  500  may indirectly vibrate the display panel  110  by a vibration transfer member directly connected to the display panel  110 . For example, the vibration transfer member may be implemented in a corresponding vibration device  500  or the display device  100 . For example, the vibration transfer member implemented in the one or more vibration device  500  may be vibration transfer plate (or a vibration transfer sheet) contacting (or coupled to) the display device  100 . Also, the vibration transfer member implemented in the display device  100  may be a backlight module disposed at the rear surface of the display panel  110 , or may be a vibration transfer plate (or a heat dissipation plate) coupled to (or attached on) the rear surface of the display panel  110 . 
     Therefore, the display apparatus according to an embodiment of the present disclosure may output a sound PVS to the forward region FD based on a vibration of the display device  100  (for example, the display panel  110 ) caused by a vibration of the one or more vibration device  500  disposed between the display device  100  and the supporting member  300 , thereby enhancing an immersion experience of a viewer watching an image displayed by the display apparatus. 
     Moreover, in the display apparatus according to an embodiment of the present disclosure, since a sound PVS is generated based on a vibration of the display device  100 , a separate speaker may not be provided, thereby enhancing a design of a set apparatus and a degree of freedom in disposition of elements. 
     Moreover, because the vibration device  500  is disposed in the gap space GS between the display device  100  and the supporting member  300 , a rear surface of the vibration device  500  may be covered by the supporting member  300 , and thus, the display apparatus according to an embodiment of the present disclosure may have a clean back design where the rear surface or a portion of the vibration device  500  is not exposed or is not seen by a user, thereby improving a rear appearance design of the display apparatus. 
     Moreover, in the display apparatus according to an embodiment of the present disclosure, the structure  510  and the vibration device  500  may be modularized as one element and may be mounted at the gap space GS between the display device  100  and the supporting member  300  through a relatively simple element mounting process, and thus, the assemble of the vibration device  500  may be improved in an assembly process performed on the display apparatus, thereby enhancing a production yield rate. 
       FIGS.  5 A to  5 E  illustrate a vibration device according to an embodiment of the present disclosure. 
     With reference to  FIGS.  4  to  5 E , a vibration generating device  501  according to an embodiment of the present disclosure may include a structure  510  and a vibration device  500 . 
     The structure  510  may be disposed at a supporting member  300 . For example, the structure  510  may be disposed at the supporting member  300  and may fix or support the vibration device  500 . According to some embodiments of the present disclosure, the structure  510  may be a metal plate which includes a metal material and has a plate shape. The structure  510  may be referred to as a supporting structure, a module structure, a plate mechanism, a base structure, a base mechanism, a module supporting frame, or a module supporting plate, but embodiments of the present disclosure are not limited thereto. 
     The structure  510  may be disposed at or fixed to the supporting member  300  by a first member  410  (or a module member). A rear surface of the structure  510  may be covered by the supporting member  300 , and thus, may be concealed without being directly exposed at an outermost rear surface of a display apparatus. For example, the rear surface of the structure  510  may be fully covered by the supporting member  300 , and thus, may be concealed without being directly exposed at the outermost rear surface of the display apparatus. 
     The first member  410  according to some embodiments of the present disclosure may be a double-sided adhesive member between the structure  510  and the supporting member  300 . The double-sided adhesive member may be a double-sided tape or a double-sided foam tape, but embodiments of the present disclosure are not limited thereto. One surface (or a front surface) of the first member  410  may be coupled to or disposed at the rear surface of the structure  510 , and the other surface (or a rear surface) of the first member  410  may be disposed at or fixed to the supporting member  300  (for example, a front surface of a first supporting member  310 ). For example, the other surface of the first member  410  may be fixed to or disposed on the front surface of the first supporting member  310  in a state where a lower protection sheet is delaminated therefrom. 
     According to some embodiments of the present disclosure, the first member  410  may be coupled (or modularized) to a rearmost surface of a vibration generating device  501  modularized as one element, for convenience of assembly between the vibration generating device  501  and a display device  100 , and may be protected by a lower protection sheet. For example, the lower protection sheet may be referred to as a lower delamination sheet or a bottom liner or a lower liner, but embodiments of the present disclosure are not limited thereto. 
     According to some embodiments of the present disclosure, the double-sided adhesive member which is the first member  410  may further include a heat transfer material. The heat transfer material may quickly transfer heat, occurring in the vibration generating device  501 , toward the supporting member  300 , and thus, may dissipate the heat of the vibration generating device  501  toward the supporting member  300 , thereby preventing or minimizing the local luminance non-uniformity of the display device  100  which occurs because heat occurring in driving of the vibration generating device  501  is locally transferred to a region of the display device  100  overlapping the vibration generating device  501 . According to some embodiments of the present disclosure, the heat transfer material may include a conductive particle or a conductive layer, but embodiments of the present disclosure are not limited thereto. For example, the double-sided adhesive member including the heat transfer material may be referred to as a heat transfer tape or a heat dissipation tape, but embodiments of the present disclosure are not limited thereto. 
     The vibration device  500  may be disposed at the structure  510  and may vibrate the display device  100 . For example, the vibration device  500  may be disposed at the structure  510  and may vibrate the display panel  110 . An integration member  520  may be disposed between the vibration device  500  and the structure  510 . For example, the vibration device  500  may be provided as one body with or disposed at the structure  510  by the integration member  520 . For example, the integration member  520  may be referred to as a module integration member, but embodiments of the present disclosure are not limited thereto. 
     The vibration device  500  may include any sound device or a vibration generator that vibrates the display device  100  according to an electrical signal. For example, the vibration device  500  may be configured to vibrate the display device  100  with a current (or a voice current) applied thereto based on Fleming&#39;s Left-Hand Rule. The vibration device  500  may be referred to as a sound generating unit, a sound generating module, a vibration generating module, a vibration generating unit, an actuator, an exciter, or a transducer, but embodiments of the present disclosure are not limited thereto. 
     The vibration device  500  may include an actuator (or an exciter) disposed to contact a rear surface of the display device  100 . For example, the vibration device  500  may include a base plate  531 , a magnet  532 , a center pole  533 , a bobbin  534 , a coil  535 , an edge frame  536 , and a damper  537 . For example, the vibration device  500  may be a vibration device including a voice coil, but embodiments of the present disclosure are not limited thereto. 
     The base plate  531  may be disposed at or fixed to the structure  510  and may be a main body of the vibration device  500 . The base plate  531  may support one or more among the magnet  532 , the center pole  533 , and the edge frame  536 . The base plate  531  may include a metal material having magnetism like iron (Fe). The base plate  531  may be referred to as a lower plate, a base frame, or a yoke, but embodiments of the present disclosure are not limited thereto. 
     The base plate  531  may include a groove portion which accommodates the magnet  532  and the bobbin  534 . For example, the groove portion may be provided concavely from an upper surface of the base plate  531  to have a circular shape. 
     The integration member  520  may be disposed between the base plate  531  and the structure  510 . For example, the base plate  531  may be provided as one body with or disposed at the structure  510  by the integration member  520 . 
     The integration member  520  may be an adhesive member. The adhesive member may be disposed between an extension portion (or a placement portion)  531   a  of the base plate  531  and the structure  510 , and thus, the base plate  531  may be disposed at the structure  510 . The integration member  520  may be an adhesive or a double-sided tape, but embodiments of the present disclosure are not limited thereto. 
     According to another embodiment of the present disclosure, the integration member  520  may include a plurality of screws. The plurality of screws may pass through the extension portion  531   a  of the base plate  531  and may be fastened to the structure  510 , and thus, the base plate  531  may be disposed at the structure  510 . 
     According to another embodiment of the present disclosure, the integration member  520  may include a bolt and a nut. The nut may be disposed at or fixed to the structure  510  overlapping the extension portion  531   a  of the base plate  531 . The bolt may pass through the extension portion  531   a  of the base plate  531  and may be fastened to the nut. The nut according to some embodiments of the present disclosure may be a self-clinching nut disposed at the structure  510 , but embodiments of the present disclosure are not limited thereto. The self-clinching nut may be a PEM® nut. 
     The magnet  532 , the center pole  533 , the bobbin  534 , and the coil  535  may be referred to as a magnetic circuit part or a magnetic vibration part, which is installed on the base plate  531  to vibrate the display device  100 . 
     The magnetic circuit part according to some embodiments of the present disclosure may have an external or dynamic magnetic type structure where the magnet  532  is disposed outward from the coil  535 , or may have an internal magnetic type or micro type structure where the magnet  532  is disposed inward from the coil  535 . The vibration device  500  including the magnetic circuit part having the internal magnetic type structure may have a totally small size and a low leakage magnetic flux. The vibration device  500  according to some embodiments of the present disclosure may have an external magnetic type or internal magnetic type structure. Hereinafter, an example where the vibration device  500  has the internal magnetic type will be described. Descriptions of the magnet  532 , the center pole  533 , the bobbin  534 , and the damper  537  may be the same as or similar to descriptions give above with reference to  FIGS.  3 A to  3 C , and thus, their repetitive descriptions may be omitted or will be briefly given. 
     The magnet  532  according to some embodiments of the present disclosure may be inserted or accommodated into the groove portion of the base plate  531 . The magnet  532  may be a permanent magnet capable of being inserted or accommodated into the bobbin  534 . For example, the magnet  532  may be a permanent magnet having a cylindrical shape capable of being inserted or accommodated into the bobbin  534 . 
     The bobbin  534  according to some embodiments of the present disclosure may be disposed on the base plate  531  and surround around the magnet  532 . The center pole  533  may be accommodated or inserted into the bobbin  534  and may guide raising or lowering of the bobbin  534 . The center pole  533  may be referred to as an elevation guider or pole pieces, but embodiments of the present disclosure are not limited thereto. 
     The edge frame  536  may be disposed at a front edge (or a front periphery) of the base plate  531  and may support the damper  537 . The edge frame  536  according to some embodiments of the present disclosure may be provided at the front edge of the base plate  531  to have a certain height and the same shape as that of the bobbin  534 . According to another embodiment of the present disclosure, the edge frame  536  may include a hollow portion that is provided at the front edge of the base plate  531  to have a certain height and the same shape as that of the bobbin  534 . 
     The damper  537  may be disposed or connected between the edge frame  536  and the magnetic circuit part. For example, the damper  537  may be disposed or connected between the edge frame  536  and the bobbin  534 . The damper  537  may be referred to as a spider, a suspension, or an edge, but embodiments of the present disclosure are not limited thereto. 
     Because the vibration device  500  is disposed between the display device  100  and the supporting member  300 , the vibration device  500  should have a relatively thin thickness so as to thinly reduce a thickness of the display apparatus or slim the display apparatus, and due to this, when a height (or a thickness) of the bobbin  534  is reduced, a sound pressure level may be lowered. Therefore, so as to solve a problem where a sound pressure level is lowered due to a reduction in height of the bobbin  534 , the inventors have designed a structure where an area of the damper  537  disposed near the bobbin  534  is wide. When an area of the damper  537  is enlarged, the inventors have recognized that a space where a line for applying a current to the coil  535  is disposed is narrowed, causing interference between the line and the damper  537 . Therefore, through various experiments, the inventors have configured the damper  537  which is formed of a conductor and performs a function of the line. 
     The damper  537  according to some embodiments of the present disclosure may include a metal material electrically connected to the coil  535 . For example, the damper  537  may be formed of stainless steel or copper (Cu), but embodiments of the present disclosure are not limited thereto. 
     The vibration device  500  according to some embodiments of the present disclosure may further include a bobbin protection member  538 . 
     The bobbin protection member  538  may be disposed at a front surface (or a front end portion) of the bobbin  534  and may transfer a rising and lowering motion (or vibration) of the bobbin  534  to the rear surface of the display device  100 . The bobbin protection member  538  according to some embodiments of the present disclosure may have a ring shape disposed on the front surface of the bobbin  534 , a disc shape covering the whole front surface of the bobbin  534 , or a cap shape surrounding the front surface and the upper outer surface of the bobbin  534 , but the shapes are not limited thereto. For example, the bobbin protection member  538  may be referred to as a bobbin ring, but embodiments of the present disclosure are not limited thereto. 
     The vibration generating device  501  according to an embodiment of the present disclosure may further include a connection member  550 . 
     The connection member  550  may be disposed between the structure  510  and the display device  100 . The connection member  550  according to some embodiments of the present disclosure may be disposed between a front edge portion (or a front periphery portion) of the structure  510  and a rear edge portion (or a rear periphery portion) of the display device  100 . For example, the connection member  550  may be a double-sided tape or a double-sided foam tape, but embodiments of the present disclosure are not limited thereto. The connection member  550  may provide a vibration space, surrounding the vibration device  500 , between the structure  510  and the display device  100 . The vibration space may be referred to as a sound pressure level space, a sound space, a sound box, a sound part, a resonance box, or a resonance part, but embodiments of the present disclosure are not limited thereto. 
     The vibration generating device  501  according to an embodiment of the present disclosure may further include a vibration transfer member  570 . 
     The vibration transfer member  570  may be connected or coupled to each of the connection member  550  and the vibration device  500  and may vibrate based on a vibration of the vibration device  500  to transfer the vibration of the vibration device  500  to the display device  100 . 
     According to some embodiments of the present disclosure, a rear edge portion or rear periphery portion of the vibration transfer member  570  may be connected or coupled to the connection member  550 , and a rear center portion of the vibration transfer member  570  may be coupled to a front surface of the bobbin  534  of the vibration device  500 , or may be coupled or connected to the bobbin protection member  538  of the vibration device  500 . 
     The vibration transfer member  570  according to some embodiments of the present disclosure may be formed of one or more materials among aluminum (Al), a magnesium (Mg), a Mg alloy, a Mg-lithium (Li) alloy, and an Al alloy, but embodiments of the present disclosure are not limited thereto. For example, the Mg alloy may include one or more materials of aluminum (Al), zinc (Zn), and manganese (Mn). The Mg alloy may be a lightest material of metal materials usable as a vibration plate of a speaker, may have relatively high non-rigidity (stiffness/specific gravity) and relatively high vibration damping ability (ability to absorb and progressively reduce vibration), and may be good in dimension stability with respect to a variation of a temperature and the elapse of time. 
     According to some embodiments of the present disclosure, a second member  430  (or a module adhesive member) may be disposed between the vibration transfer member  570  and the display device  100 . For example, the front surface of the vibration transfer member  570  may be coupled or connected to the rear surface of the display device  100  by the second member  430 . 
     The second member  430  may be a double-sided adhesive member between the display device  100  and the vibration transfer member  570 . The double-sided adhesive member may be a double-sided tape or a double-sided foam tape, but embodiments of the present disclosure are not limited thereto. One surface (or a front surface) of the second member  430  may be disposed on or coupled to the rear surface of the display device  100 , and the other surface (or a rear surface) of the second member  430  may be disposed on or coupled to the front surface of the vibration transfer member  570 . For example, the one surface of the second member  430  may be disposed at or fixed to the rear surface of the display device  100  in a state where an upper protection sheet is delaminated. 
     According to some embodiments of the present disclosure, the second member  430  may be coupled (or modularized) to an uppermost surface of the vibration generating device  501  modularized as one element, for convenience of assembly between the vibration generating device  501  and the display device  100 , and may be protected by the upper protection sheet. For example, the upper protection sheet may be referred to as an upper delamination sheet or a top liner (or an upper liner), but embodiments of the present disclosure are not limited thereto. 
     For example, all of the vibration transfer member  570  and the second member  430  may be omitted. For example, the vibration generating device  501  may include the upper protection sheet coupled or connected to each of the connection member  550  and the vibration device  500 . The upper protection sheet may be coupled or connected to each of the connection member  550  and the vibration device  500  to cover the whole front surface of the vibration generating device  501 , and thus, in a transfer process after a modularization process performed on the vibration generating device  501  modularized as one element, each of the vibration device  500  and the connection member  550  of the vibration generating device  501  may be prevented from being externally exposed and penetration of particles such as dust into the vibration generating device  501  may be prevented. The upper protection sheet may be delaminated from the vibration generating device  501  immediately before an assembly process between the vibration generating device  501  and the display device  100 . 
     Therefore, the vibration generating device  501  according to an embodiment of the present disclosure may be disposed between the display device  100  and the supporting member  300  in a state where the structure  510  and the vibration device  500  are modularized as one element, and thus, by the display device  100  as a vibration plate, a sound PVS based on a vibration of the display panel  110  may be output and an outermost rear surface of the display apparatus may not expose the vibration device  501 , thereby improving a rear appearance design of the display apparatus. 
     With reference to  FIGS.  5 B and  5 C , an adhesive member  522  may be disposed between the vibration device  500  and the structure  510 . The adhesive member  522  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. When the adhesive member  522  is provided, comparing with a screw or a nut and a bolt, an assembly process may be simplified and a hole for fastening with a screw or a nut and a bolt or an extension portion of a plate may not be needed, thereby providing a vibration device which is slimmer. A description of the vibration device is the same as description given above with reference to  FIGS.  3 A to  3 C, and  5 A , and thus, the repetitive description thereof may be omitted. 
     With reference to  FIG.  5 B , the vibration device  500  may be asymmetrically disposed. When the vibration device  500  is asymmetrically disposed, a dip phenomenon in a specific frequency may be reduced. For example, when a standing wave occurs in upper, lower, left, and right portions with respect to the vibration device  500 , the dip phenomenon may occur in the upper, lower, left, and right portions, but when the vibration device  500  is asymmetrically disposed, a phenomenon where the standing wave occurs simultaneously in the upper, lower, left, and right portions may be reduced. Accordingly, the dip phenomenon may be reduced, and thus, a sound characteristic may be more enhanced. 
     With reference to  FIGS.  5 D and  5 E , a supporting member  300  may include a first supporting member  310  and a second supporting member  350 . Descriptions of the first supporting member  310  and the second supporting member  350  are the same as descriptions given above with reference to  FIG.  2   , and thus, the repetitive description thereof may be omitted. 
     With reference to  FIG.  5 D , the vibration device  500  may be accommodated into the first supporting member  310 . For example, the vibration device  500  may be disposed at a removed portion of the first supporting member  310 . The vibration device  500  may be attached at the second supporting member  350  by an adhesive member  522 . The adhesive member  522  may be disposed between the vibration device  500  and the second supporting member  350 . The first supporting member  310  and the vibration device  500  may be attached by the adhesive member  522 . As another embodiment of the present disclosure, the adhesive member  522  may be further disposed between the vibration device  500  and the first supporting member  310 . For example, the adhesive member  522  may be further disposed between an extension portion  531   a  of a base plate  531  and the first supporting member  310 . The adhesive member  522  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. A portion of the first supporting member  310  may be removed and the vibration device  500  may be disposed at a removed region of the first supporting member  310 , and thus, a thickness of the vibration device  500  may be reduced, thereby decreasing a thickness of a display apparatus. Also, when the vibration device  500  is disposed adjacent to the first supporting member  310  and/or the second supporting member  350 , an abnormal vibration may occur when the vibration device  500  vibrates, and thus, the vibration device  500  may be spaced apart from the first supporting member  310  and/or the second supporting member  350  by an interval or a distance D. For example, the vibration device  500  may be spaced apart from the first supporting member  310  and/or the second supporting member  350  by the interval or the distance D. For example, the interval or the distance D may be 1 mm or more, but embodiments of the present disclosure are not limited thereto. 
     With reference to  FIG.  5 E , the vibration device  500  may be accommodated between the first supporting member  310  and between the second supporting member  350 . For example, the base plate  531  of the vibration device  500  may have an external appearance. The base plate  531  of the vibration device  500  may be disposed between the first supporting member  310  and between the second supporting member  350 . The base plate  531  of the vibration device  500  may be configured to penetrate the first supporting member  310  and the second supporting member  350 . The adhesive member  522  may be disposed between the vibration device  500  and the first supporting member  310 . For example, the adhesive member  522  may be disposed at the extension portion  531   a  of the base plate  531  and one side of the first supporting member  310 . The adhesive member  522  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. Since the base plate  531  of the vibration device  500  is configured to have an external appearance, a thickness of the vibration device  500  may be reduced, thereby decreasing a thickness of the display apparatus. Also, when the vibration device  500  is disposed adjacent to the first supporting member  310  and the second supporting member  350 , an abnormal vibration may occur when the vibration device  500  vibrates, and thus, the vibration device  500  may be spaced apart from the first supporting member  310  and the second supporting member  350  by an interval or a distance D. For example, the vibration device  500  may be spaced apart from the first supporting member  310  and the second supporting member  350  by the interval or the distance D. For example, the interval or the distance D may be 1 mm or more, but embodiments of the present disclosure are not limited thereto. 
     The one or more vibration device  500  may realize a 2-channel sound including a left sound and a right sound, and thus, the inventors have recognized that it is difficult to reproduce or generate a sound at an upper portion and a lower portion. For example, a multi-channel sound may be reproduced by a sound bar, but an upper channel may be an indirect sound which is generated by reproducing a sound through reflection by a ceiling, and thus, the inventors have recognized that there is a problem where it is difficult to reproduce a desired sound due to a position difference between a displayed screen and a sound image. Therefore, the inventors have performed various experiments for reproducing a real sound instead of an indirect sound. Through the various experiments, the inventors have invented a display apparatus having a new structure for realizing a real sound and a multi-channel sound. This will be described below. 
       FIGS.  6 A to  6 D  illustrate a display apparatus including a vibration device according to an embodiment of the present disclosure. 
     With reference to  FIGS.  6 A and  6 B , the display apparatus may include a display device  100  including a display panel  110  which displays an image and includes a first region ( 1 ), a second region ( 2 ), a third region ( 3 ), a fourth region ( 4 ), a fifth region ( 5 ), and a sixth region ( 6 ). For example, a rear surface of the display device  100  may include the first to sixth regions ( 1 ) to ( 6 ). The first region ( 1 ), the second region ( 2 ), and the third region ( 3 ) may be disposed at an upper portion of the display device  100 . For example, the third region ( 3 ) may be disposed between the first region ( 1 ) and the second region ( 2 ). The fourth to sixth regions ( 4 ) to ( 6 ) may be disposed at a lower portion of the first to third regions ( 1 ) to ( 3 ). For example, the sixth region ( 6 ) may be disposed between the fourth region ( 4 ) and the fifth region ( 5 ). 
     At least one or more vibration devices may be disposed at at least one or more among the first to sixth regions ( 1 ) to ( 6 ). In the following embodiments, an example where a vibration device is disposed at a rear surface of the display device  100  (for example, a rear surface of the display panel  110 ) will be described, but embodiments of the present disclosure are not limited thereto. For example, the vibration device may be disposed between the display panel  110  and a supporting member  300 . For example, the vibration device may be disposed between a rear surface of the display panel  110  and an upper surface of the supporting member  300 . As another embodiment of the present disclosure, as illustrated in  FIGS.  5 A to  5 E , the vibration device may be configured to be modularized as one element (or one component). 
     According to some embodiments of the present disclosure, the display apparatus may further include a partition. For example, the partition may be disposed between the display panel  110  and the supporting member  300 . The partition may be an air gap or a space where a sound is generated when the display panel  110  is vibrated by the vibration device. An air gap or a space which generates or outputs a sound may be referred to as a partition. The partition may separate a sound or may separate a channel, thereby preventing or decreasing the occurrence of a nontransparent sound caused by interference of a sound. The partition may be referred to as an enclosure or a baffle, but embodiments of the present disclosure are not limited thereto. In the following embodiments, an example where a partition is disposed at a supporting member will be described. However, embodiments of the present disclosure are not limited thereto, and the partition may be disposed at a rear surface of a display panel. To illustrate the vibration device and the partition, an example where the vibration device and the partition are disposed at the supporting member will be described. For example, when the partition is disposed at the supporting member, an adverse influence of image quality of the display panel caused by the partition disposed at the display panel may be reduced. 
     With reference to  FIG.  6 A , a partition may be disposed to separate a left sound and a right sound which are output by a vibration device disposed at a rear surface of a display panel  110 . For example, the partition may be disposed between the display panel  110 , corresponding to first to sixth regions ( 1 ) to ( 6 ) of the display panel  110 , and a supporting member  300 . For example, a first partition  1711  may be disposed between the first region ( 1 ) and the third region ( 3 ). A second partition  1712  may be disposed between the second region ( 2 ) and the third region ( 3 ). A third partition  1721  may be disposed between the fourth region ( 4 ) and the sixth region ( 6 ). A fourth partition  1722  may be disposed between the fifth region ( 5 ) and the sixth region ( 6 ). For example, the first partition  1711  and the second partition  1712  may separate left and right channels or left and right sounds, which are generated by a first vibration device  500 HL and a second vibration device  500 HR. For example, the third and fourth partitions  1721  and  1722  may separate the left and right channels or the left and right sounds generated by the third vibration device W 1  and fourth vibration device W 2 . 
     The first vibration device  500 HL and the second vibration device  500 HR may be further configured for implementing a multi-channel sound, and a partition should be configured for separating channels or sounds, generated by the first and second vibration devices  500 HL and  500 HR, from channels or sounds generated by the third and fourth vibration devices W 1  and W 2 . When the first to fourth partitions  1711  to  1722  are disposed, left and right sounds or left and right channels may be separated from one another. A partition for generating a sound in each vibration device should be configured so that an upper portion sound or an upper channel are separated from a lower portion sound or a lower channel and vibration devices disposed at regions of the rear surface of the display panel  110  implement independent sounds for each region. 
     A partition may be configured to separate an upper channel or a height channel of the display panel  110  from a center channel of the display panel  110 . For example, a fifth partition  1731  may separate the upper channel or a height channel of the display panel  110  from the center channel of the display panel  110 . For example, the fifth partition  1731  may separate channels or sounds, generated by a first vibration device  500 HL and a second vibration device  500 HR disposed at an upper portion of the display panel  110 , from channels or sounds generated by a third vibration device W 1 , a fourth vibration device W 2 , and a fifth vibration device  500 C disposed at a lower portion of the display panel  110 . A sixth partition  1732  may be disposed at a lower portion of the display panel  110  and may be separated from a driver for driving the display panel  110 . For example, the sixth partition  1732  may be disposed at lower portions of the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C. For example, the sixth partition  1732  may separate the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C from the driver for driving the display panel  110 . The fifth partition  1731  may be disposed between the first to third regions ( 1 ) to ( 3 ) and the fourth to sixth regions ( 4 ) to ( 6 ). The sixth partition  1732  may be disposed at a lower portion of the fourth to sixth regions ( 4 ) to ( 6 ). 
     The first to sixth partitions  1711  to  1732  may be disposed at the supporting member  300 . For example, the first to sixth partitions  1711  to  1732  may be disposed at an upper surface of the supporting member  300 . For example, the first to sixth partitions  1711  to  1732  may be disposed between the display panel  110  and the supporting member  300 . For example, the first to sixth partitions  1711  to  1732  may be disposed between the rear surface of the display panel  110  and the upper surface of the supporting member  300 . 
     With reference to  FIG.  6 B , the display apparatus may include a first to fifth partitions  1711  to  1731 , and a seventh partition  1750  provided between a supporting member  300  and a display panel  110 . For example, the seventh partition  1750  may be disposed at a periphery of the supporting member  300 . For example, the seventh partition  1750  may be disposed at a periphery of an upper surface of the supporting member  300 . The seventh partition  1750  may be a whole region of four sides of an outer portion of the upper surface of the supporting member  300 . As another embodiment of the present disclosure, the seventh partition  1750  may be disposed at a periphery of a rear surface of the display device  100  (for example, the display panel  110 ). For example, the seventh partition  1750  may surround a periphery of the display device  100  (for example, the display panel  110 ). The seventh partition  1750  may be a whole region of four sides of an outer portion of the rear surface of the display panel  110 . The seventh partition  1750  may be a whole region of the rear surface of the display panel  110  or a whole region of the supporting member  300 . For example, the seventh partition  1750  may be disposed to surround the first to fifth vibration devices  500 HL to  500 C. For example, the seventh partition  1750  may be disposed along a region between a rear periphery of the display panel  110  and a front periphery of the supporting member  300  to surround a vibration device. The seventh partition  1750  may be referred to as an edge partition, a sound blocking member, an edge enclosure, or an edge baffle, but embodiments of the present disclosure are not limited thereto. The seventh partition  1750  may be disposed along a shape of the display device  100  so as to prevent a wave phenomenon of the display device  100 . The wave phenomenon may be a phenomenon where a shape of a partition swells to a screen of a display device when a thickness of a substrate configuring the display device is thinned, and moreover, may be a problem where some regions of a display panel is recognized unevenly because the display device is not flat or a supporting member is not flat. For example, when the seventh partition  1750  is an adhesive member for attaching the display panel  110  and the supporting member  330  described in  FIGS.  1  to  5 E , the adhesive member described in  FIGS.  1  to  5 E  may be omitted, and the seventh partition  1750  may act as an adhesive member. However, embodiments of the present disclosure are not limited thereto, and the adhesive member for attaching the display panel  110  and the supporting member  300  may be provided at the supporting member  300  or the rear surface of the display panel  110 . For example, the seventh partition  1750  may be disposed to be adjacent to or to contact a connection member  550  and may be surrounded by the connection member  550 . As another embodiment of the present disclosure, the seventh partition  1750  and the connection member  550  may be provided as one body (or a single body). 
     Therefore, because the display apparatus according to an embodiment of the present disclosure further include the seventh partition  1750 , a peak or dip phenomenon may be reduced, and the flatness of a sound characteristic may be improved. For example, the peak phenomenon may be a phenomenon where a sound pressure level bounces in a specific frequency, and the dip phenomenon may be a phenomenon where a low sound pressure level is generated because a specific frequency is not generated. For example, the flatness of the sound characteristic may be a magnitude of a deviation between a highest sound pressure level and a lowest sound pressure level. 
     The first to seventh partitions  1711  to  1750  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. When the first to seventh partitions  1711  to  1750  is configured with a double-sided tape or a double-sided foam pad, an adhesive force may be enhanced in a process of attaching the rear surface of the display panel  110  on the upper surface of the supporting member  300 . For example, at least one or more of the first to seventh partitions  1711  to  1750  may include a material having elasticity which enables a certain degree of compression. For example, the first to seventh partitions  1711  to  1750  may include polyurethane, polyolefin, or polyethylene, but embodiments of the present disclosure are not limited thereto. 
     According to some embodiments of the present disclosure, at least one first vibration device  500 HL may be disposed at a first region ( 1 ) of a rear surface of a display panel. At least one second vibration device  500 HR may be disposed at a second region ( 2 ) of the rear surface of the display panel. For example, the first vibration device  500 HL may be an upper left channel or a height left channel. For example, the second vibration device  500 HR may be an upper right channel or a height right channel. 
     According to some embodiments of the present disclosure, at least one third vibration device W 1  may be disposed at a fourth region ( 4 ) of the rear surface of the display panel. At least one fourth vibration device W 2  may be disposed at a fifth region ( 5 ) of the rear surface of the display panel. At least one fifth vibration device  500 C may be disposed at a sixth region ( 6 ) of the rear surface of the display panel. For example, the third vibration device W 1  may be a left channel, the fourth vibration device W 2  may be a right channel, and the fifth vibration device  500 C may be a center channel. 
     For example, the first and second vibration devices  500 HL and  500 HR may be an upper channel or a height channel. The third to fifth vibration devices W 1 , W 2 , and  500 HC may be a main channel. For example, the first and second vibration devices  500 HL and  500 HR may be a vibration device which outputs a full-range sound. The third to fifth vibration devices W 1 , W 2 , and  500 HC may be a vibration device which outputs a full-range sound. For example, a sound band of a full range may be about 300 Hz or more, but embodiments of the present disclosure are not limited thereto. For example, when the third vibration device W 1  and the fourth vibration device W 2  are provided, a left sound and a right sound may be reproduced. Moreover, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  500 HL and the second vibration device  500 HR are further provided, an upper channel (or a height channel or an upper sound) may be reproduced, thereby realizing a real sound for the upper channel. For example, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  500 HL and the second vibration device  500 HR are further provided, there may not be a position difference between a screen and a sound image, and thus, a sound image based on the screen may be implemented, thereby realizing a real sound based on a position. Also, because the fifth vibration device  500 C configures a center channel in addition to a left sound and a right sound, a display apparatus for outputting a multi-channel sound may be implemented. 
     According to some embodiments of the present disclosure, a vibration device may be not configured at third region ( 3 ). Therefore, vibrations of the first vibration device  500 HL and the second vibration device  500 HR may be attenuated and absorbed in the third region ( 3 ) of the display panel  110 , and thus, the transfer of a sound from the first region ( 1 ) to the second region ( 2 ) may be blocked or reduced and the transfer of a sound from the second region ( 2 ) to the first region ( 1 ) may be blocked or reduced. Accordingly, a degradation in sound quality caused by interference of sounds generated in the first region ( 1 ) and the second region ( 2 ) may be reduced, and a sound characteristic of a middle-high-pitched sound band may be more enhanced. For example, the middle-pitched sound band may be about 200 Hz to about 3 kHz, the high-pitched sound band may be 3 kHz or more, and the low-pitched sound band may be 200 Hz or less. However, a range of a sound band is not limited thereto. 
     Therefore, the display apparatus according to an embodiment of the present disclosure may include five vibration devices and may be configured with a plurality of vibration devices including an upper channel or a height channel and a main channel, thereby providing five channels. Also, the five vibration devices may be independently supplied with and driven by a sound signal, and thus, each of the five vibration devices may reproduce an independent sound channel. 
     For example, because the third vibration device W 1  and the fourth vibration device W 2  is configured as a woofer-integrated vibration device, a 3.1.2-channel or a 3.2.2-channel may be implemented. Also, because the third vibration device W 1  and the fourth vibration device W 2  are configured as a woofer-integrated vibration device, it is not needed to separately provide a woofer for reproducing a sound of the low-pitched sound band. The woofer-integrated vibration device will be described below with reference to  FIGS.  11 A and  11 B . 
     According to some embodiments of the present disclosure, the third vibration device W 1  and the fourth vibration device W 2  may be configured as the same vibration device, for the left-right symmetricity of a sound. For example, one or more of the first vibration device  500 HL and the second vibration device  500 HR may be configured as a vibration device which differs from one or more of the third vibration device W 1  and the fourth vibration device W 2 . For example, the first vibration device  500 HL and the second vibration device  500 HR may be configured as a coil type vibration device. The coil type vibration device may be the vibration device described above with reference to  FIGS.  1  to  5 E . For example, the third vibration device W 1  and the fourth vibration device W 2  may be configured as a woofer-integrated vibration device or a vibration device including a woofer. For example, one or more of the first vibration device  500 HL and the second vibration device  500 HR may be configured as a vibration device which differs from one or more of the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C. The fifth vibration device  500 C may be configured as the same vibration device as the first vibration device  500 HL and the second vibration device  500 HR. For example, the fifth vibration device  500 C may be configured as the coil type vibration device. Therefore, a display apparatus for realizing a 3.2.2-channel may be provided. Also, the first vibration device  500 HL, the second vibration device  500 HR, and the fifth vibration device  500 C may be configured as a vibration device which is cheaper in cost than the third vibration device W 1  and the fourth vibration device W 2 . Accordingly, channels of the third vibration device W 1  and the fourth vibration device W 2  which are main channels may be reinforced, and thus, a sound may be enhanced and the cost of a vibration device may be reduced. 
     The inventors have recognized that it is difficult to output a sound of a low-pitched sound band despite a case where a partition is configured to separate a channel or a sound of the upper portion and a channel or a sound of the lower portion. Therefore, the inventors have performed various experiments for implementing a sound of the low-pitched sound band, and have implemented a multi-channel sound including the low-pitched sound band based on the various experiments. 
     With reference to  FIG.  6 A , a size of one or more among a first partition  1711  and a second partition  1712  may be configured to differ from one or more among a third partition  1721  and a fourth partition  1722 . For example, a length of one or more among the first partition  1711  and the second partition  1712  may be configured to differ from one or more among the third partition  1721  and the fourth partition  1722 . For example, a length a 1  of the first partition  1711  may be configured to differ from a length a 4  of the third partition  1721 . For example, the length a 1  of the first partition  1711  may be configured to be smaller than the length a 4  of the third partition  1721 . Accordingly, the first vibration device  500 HL and the second vibration device  500 HR may output a sound band of 300 Hz or more, and the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C may output a sound band of a full range.

For example, a stereo sound and a vivid sound may be provided at upward, downward, left, and right sides or portions based on a position of an object or a person in a displayed screen. According to an embodiment of the present disclosure, comparing with a sound bar, the first vibration device  500 HL and the second vibration device  500 HR which are upper channels or height channels may generate a sound at a height position, thereby providing a vibration device for realizing a sound without needing a separate algorithm. 
       FIGS.  7 A and  7 B  illustrate a display apparatus including a vibration device according to another embodiment of the present disclosure. 
     With reference to  FIGS.  7 A and  7 B , the display apparatus according to another embodiment of the present disclosure may include a display device  100  including a display panel  110  including a first region ( 1 ), a second region ( 2 ), a third region ( 3 ), a fourth region ( 4 ), a fifth region ( 5 ), and a sixth region ( 6 ). One or more vibration devices may be disposed at one or more of the first to the sixth regions ( 1 ) to ( 6 ). 
     According to some embodiments of the present disclosure, at least one first vibration device  500 HL may be disposed at a first region ( 1 ) of a rear surface of the display panel  110 , and at least one second vibration device  500 HR may be disposed at a second region ( 2 ) of the rear surface of the display panel  110 . For example, the first vibration device  500 HL may be an upper left channel or a height left channel. For example, the second vibration device  500 HR may be an upper right channel or a height right channel. 
     At least one third vibration device  500 L may be disposed at a fourth region ( 4 ) of the rear surface of the display panel  110 , and at least one fourth vibration device  500 R may be disposed at a fifth region ( 5 ) of the rear surface of the display panel  110 .

The first vibration device  500 HL and the second vibration device  500 HR may be a vibration device which outputs a sound of a full range. The third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C may be a vibration device which outputs a sound of a full range. For example, a sound band of a full range may be about 300 Hz or more, but embodiments of the present disclosure are not limited thereto. For example, in a case where the third vibration device  500 L and the fourth vibration device  500 R are provided, a left sound and a right sound may be reproduced. Moreover, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  500 HL and the second vibration device  500 HR are further provided, the upper channel or a height channel may be reproduced, thereby realizing a real sound for the upper channel. For example, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  500 HL and the second vibration device  500 HR are further provided, there may not be a position difference between a screen and a sound image, and thus, a sound image based on the screen may be implemented, thereby realizing a real sound based on a position. Also, because the fifth vibration device  500 C configures a center channel in addition to a left sound and a right sound, a display apparatus for outputting a multi-channel sound may be implemented. 
     According to some embodiments of the present disclosure, the third region ( 3 ) may not configure a vibration device. Therefore, vibrations of the first vibration device  500 HL and the second vibration device  500 HR may be attenuated and absorbed in the third region ( 3 ) of the display panel  110 , and thus, the transfer of a sound from the first region ( 1 ) to the second region ( 2 ) may be blocked or reduced and the transfer of a sound from the second region ( 2 ) to the first region ( 1 ) may be blocked or reduced. Accordingly, a degradation in sound quality caused by interference of sounds generated in the first region ( 1 ) and the second region ( 2 ) may be reduced, and a sound characteristic of a middle-pitched sound band and a high-pitched sound band may be more enhanced. 
     Therefore, the display apparatus according to an embodiment of the present disclosure may include five vibration devices and may be configured with a plurality of vibration devices including an upper channel or a height channel and a main channel, thereby providing a display apparatus including five channels. Also, the five vibration devices may be independently supplied with and driven by a sound signal, and thus, each of the five vibration devices may reproduce an independent sound channel. 
     According to some embodiments of the present disclosure, the third vibration device  500 L and the fourth vibration device  500 R may be configured as the same vibration device, for the left-right symmetricity of a sound. For example, the third vibration device  500 L and the fourth vibration device  500 R may be configured as a coil type vibration device. The coil type vibration device may be the vibration device described above with reference to  FIGS.  1  to  5 E . For example, one or more of the first vibration device  500 HL and the second vibration device  500 HR may be configured as a vibration device which is the same as one or more of the third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C. The fifth vibration device  500 C may be configured as a vibration device which is the same as the first vibration device  500 HL and the second vibration device  500 HR. For example, the fifth vibration device  500 C may be configured as the coil type vibration device. Therefore, a display apparatus for realizing a 3.2.2-channel may be provided. 
     With reference to  FIGS.  7 A and  7 B , a size of one or more among a first partition  1711  and a second partition  1712  may be configured to differ from one or more among a third partition  1721  and a fourth partition  1722 . A size of one or more among a fifth partition  1731  and a sixth partition  1732  may be configured to differ from one or more among the first partition  1711  and the second partition  1712 . For example, a length of one or more among the first partition  1711  and the second partition  1712  may be configured to differ from one or more among the third partition  1721  and the fourth partition  1722 . For example, a length of one or more of the fifth partition  1731  and the sixth partition  1732  may be configured to differ from one or more of the first partition  1711  and the second partition  1712 . Therefore, the first vibration device  500 HL and the second vibration device  500 HR may output a sound band of 300 Hz or more, and the third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C may output a sound band of a full range. Descriptions of the partitions and the first to sixth regions ( 1 ) to ( 6 ) may be the same as descriptions given above with reference to  FIGS.  6 A and  6 B , and thus, repetitive descriptions are omitted. 
     Therefore, according to an embodiment of the present disclosure, sizes of partitions near a vibration device may be configured to differently, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or more and/or a sound band of a full range. 
       FIGS.  8 A and  8 B  illustrate a display apparatus including a vibration device according to another embodiment of the present disclosure. 
     With reference to  FIGS.  8 A and  8 B , the display apparatus according to another embodiment of the present disclosure may include a display device  100  including a display panel  110  including a first region ( 1 ), a second region ( 2 ), a third region ( 3 ), a fourth region ( 4 ), a fifth region ( 5 ), and a sixth region ( 6 ). One or more vibration devices may be disposed at one or more of the first to sixth region ( 1 ) to ( 6 ). 
     According to some embodiments of the present disclosure, at least one first vibration device  600 HL may be disposed at a first region ( 1 ) of a rear surface of the display panel  110 , and at least one second vibration device  600 HR may be disposed at a second region ( 2 ) of the rear surface of the display panel  110 . For example, each of the first vibration device  600 HL and the second vibration device  600 HR may have a square or rectangular shape. For example, the first vibration device  600 HL may be an upper left channel or a height left channel. For example, the second vibration device  600 HR may be an upper right channel or a height right channel. 
     At least one third vibration device W 1  may be disposed at a fourth region ( 4 ) of the rear surface of the display panel  110 , and at least one fourth vibration device W 2  may be disposed at a fifth region ( 5 ) of the rear surface of the display panel  110 . At least one fifth vibration device  500 C may be disposed at a sixth region ( 6 ) of the rear surface of the display panel  110 . For example, the third vibration device W 1  may be a left channel, the fourth vibration device W 2  may be a right channel, and the fifth vibration device  500 C may be a center channel. 
     For example, the first vibration device  600 HL and the second vibration device  600 HR may be an upper channel or height channel, and the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C may be a main channel. The first vibration device  600 HL and the second vibration device  600 HR may be a vibration device which outputs a sound of a full range. The third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C may be a vibration device which outputs a sound of a full range. For example, a sound band of a full range may be about 300 Hz or more, but embodiments of the present disclosure are not limited thereto. For example, in a case where the third vibration device W 1  and the fourth vibration device W 2  are provided, a left sound and a right sound may be reproduced. Moreover, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  600 HL and the second vibration device  600 HR are further provided, an upper channel or a height channel may be reproduced, thereby realizing a real sound for the upper channel. For example, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  600 HL and the second vibration device  600 HR are further provided, there may not be a position difference between a screen and a sound image, and thus, a sound image based on the screen may be implemented, thereby realizing a real sound based on a position. Also, because the fifth vibration device  500 C configures a center channel in addition to a left sound and a right sound, a display apparatus for outputting a multi-channel sound may be implemented. 
     According to some embodiments of the present disclosure, the third region ( 3 ) may not configure a vibration device. Therefore, vibrations of the first vibration device  600 HL and the second vibration device  600 HR may be attenuated and absorbed in the third region ( 3 ) of the display panel  110 , and thus, the transfer of a sound from the first region ( 1 ) to the second region ( 2 ) may be blocked or reduced and the transfer of a sound from the second region ( 2 ) to the first region ( 1 ) may be blocked or reduced. Accordingly, a degradation in sound quality caused by interference of sounds generated in the first region ( 1 ) and the second region ( 2 ) may be reduced, and a sound characteristic of a middle-pitched sound band and a high-pitched sound band may be more enhanced. 
     Therefore, the display apparatus according to an embodiment of the present disclosure may include five vibration devices and may be configured with a plurality of vibration devices including an upper channel or a height channel and a main channel, thereby providing a display apparatus including five channels. Also, the five vibration devices may be independently supplied with and driven by a sound signal, and thus, each of the five vibration devices may reproduce an independent sound channel. 
     For example, because the third vibration device W 1  and the fourth vibration device W 2  is configured as a woofer-integrated vibration device, a 3.1.2-channel or a 3.2.2-channel may be implemented. Also, because the third vibration device W 1  and the fourth vibration device W 2  are configured as a woofer-integrated vibration device, it is not needed to separately provide a woofer for reproducing a sound of the low-pitched sound band. 
     According to some embodiments of the present disclosure, the third vibration device W 1  and the fourth vibration device W 2  may be configured as the same vibration device, for the left-right symmetricity of a sound. One or more of the first vibration device  600 HL and the second vibration device  600 HR may be configured as a vibration device which differs from one or more of the third vibration device W 1  and the fourth vibration device W 2 . For example, one or more of the first vibration device  600 HL and the second vibration device  600 HR may be configured as a film type vibration device. The film type vibration device will be described below with reference to  FIGS.  12  to  17   . For example, one or more of the third vibration device W 1  and the fourth vibration device W 2  may be configured as a woofer-integrated vibration device. For example, one or more of the first vibration device  600 HL and the second vibration device  600 HR may be configured as a vibration device which differs from one or more of the third vibration device W 1 , the fourth vibration device W 2 , and the fifth vibration device  500 C. For example, the fifth vibration device  500 C may be configured as a coil type vibration device. For example, the first to fifth vibration devices  600 HL to  500 C may be configured as two or more different vibration devices. Accordingly, a display apparatus for realizing a 3.2.2-channel may be implemented. 
     With reference to  FIG.  8 A , a size of one or more among a first partition  1711  and a second partition  1712  may be configured to differ from one or more among a third partition  1721  and a fourth partition  1722 . For example, a length of one or more among the first partition  1711  and the second partition  1712  may be configured to differ from one or more among the third partition  1721  and the fourth partition  1722 . For example, a length a 1  of the first partition  1711  may be configured to differ from a length a 4  of the third partition  1721 .

For example, a size of the fifth partition  1731  at the one or more sides of the fifth vibration device  500 C may differ from the second partition  1712  at one or more sides of the second vibration device  600 HR. For example, a size of the fifth partition  1731  at the one or more sides of the fifth vibration device  500 C may be smaller than the second partition  1712  at the one or more sides of the second vibration device  600 HR. For example, a size of the fifth partition  1731  at the one or more sides of the fifth vibration device  500 C may differ from the fifth partition  1731  at one or more sides of the second vibration device  600 HR. For example, a size of the fifth partition  1731  at the one or more sides of the fifth vibration device  500 C may be smaller than the fifth partition  1731  at the one or more sides of the second vibration device  600 HR. 
     According to some embodiments of the present disclosure, the display apparatus may include the fifth partition  1731  and the sixth partition  1732  at one or more sides of the fifth vibration device  500 C. A size of one or more among the fifth partition  1731  and the sixth partition  1732  may be the same as one or more among the fifth partition  1731  and the sixth partition  1732  at one or more sides of the third vibration device W 1  and the fourth vibration device W 2 . For example, a size of the fifth partition  1731  at one or more sides of the fifth vibration device  500 C may be the same as the fifth partition  1731  at one or more sides of the third vibration device W 1 . For example, a size of the sixth partition  1732  at one or more sides of the fifth vibration device  500 C may be the same as the sixth partition  1732  at one or more sides of the third vibration device W 1 . For example, a size of the fifth partition  1731  at the one or more sides of the fifth vibration device  500 C may be the same as the fifth partition  1731  at one or more sides of the fourth vibration device W 2 . For example, a size of the sixth partition  1732  at the one or more sides of the fifth vibration device  500 C may be the same as the sixth partition  1732  at one or more sides of the fourth vibration device W 2 . 
     With reference to  FIGS.  8 A and  8 B , a size of a first region ( 1 ) and a second region ( 2 ) may be the same as or different from a third region ( 3 ). When a size of the third region ( 3 ) is greater than the first region ( 1 ) and the second region ( 2 ), a sound of the low-pitched sound band may be more enhanced. For example, a size of a fourth region ( 4 ), a size of a fifth region ( 5 ), and a size of a sixth region ( 6 ) may be the same. 
     Therefore, according to an embodiment of the present disclosure, sizes of partitions near a vibration device may be differently adjusted, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or more and/or a sound band of a full range. For example, a size of a partition of the first vibration device  600 HL and the second vibration device  600 HR which are film type vibration devices may be configured to be greater than a partition of the other vibration devices, and thus, a sound band of 180 Hz or more and/or a sound band of a full range may be output. 
       FIGS.  9 A and  9 B  illustrate a display apparatus including a vibration device according to another embodiment of the present disclosure. 
     With reference to  FIGS.  9 A and  9 B , the display apparatus may include a display device  100  including a display panel  110  including a first region ( 1 ), a second region ( 2 ), a third region ( 3 ), a fourth region ( 4 ), a fifth region ( 5 ), and a sixth region ( 6 ). One or more vibration devices may be disposed at one or more of the first to sixth regions ( 1 ) to ( 6 ). 
     According to some embodiments of the present disclosure, at least one first vibration device  600 HL may be disposed at a first region ( 1 ) of a rear surface of the display panel  110 , and at least one second vibration device  600 HR may be disposed at a second region ( 2 ) of the rear surface of the display panel  110 . For example, the first vibration device  600 HL may be an upper left channel or a height left channel. For example, the second vibration device  600 HR may be an upper right channel or a height right channel. 
     At least one third vibration device  500 L may be disposed at a fourth region ( 4 ) of the rear surface of the display panel  110 , and at least one fourth vibration device  500 R may be disposed at a fifth region ( 5 ) of the rear surface of the display panel  110 . At least one fifth vibration device  500 C may be disposed at a sixth region ( 6 ) of the rear surface of the display panel  110 . For example, the third vibration device  500 L may be a left channel, the fourth vibration device  500 R may be a right channel, and the fifth vibration device  500 C may be a center channel. 
     For example, the first vibration device  600 HL and the second vibration device  600 HR may be an upper channel or a height channel, and the third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C may be a main channel. The first vibration device  600 HL and the second vibration device  600 HR may be a vibration device which outputs a sound of a full range. The third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C may be a vibration device which outputs a sound of a full range. For example, a sound band of a full range may be about 300 Hz or more, but embodiments of the present disclosure are not limited thereto. For example, when the third vibration device  500 L and the fourth vibration device  500 R are provided, a left sound and a right sound may be reproduced. Moreover, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  600 HL and the second vibration device  600 HR are further provided, an upper channel or a height channel may be reproduced, thereby realizing a real sound for the upper channel. For example, in the display apparatus according to an embodiment of the present disclosure, because the first vibration device  600 HL and the second vibration device  600 HR are further provided, there may not be a position difference between a screen and a sound image, and thus, a sound image based on the screen may be implemented, thereby realizing a real sound based on a position. Also, because the fifth vibration device  500 C configures a center channel in addition to a left sound and a right sound, a display apparatus for outputting a multi-channel sound may be implemented. 
     According to some embodiments of the present disclosure, the third region ( 3 ) may not configure a vibration device. Therefore, vibrations of the first vibration device  600 HL and the second vibration device  600 HR may be attenuated and absorbed in the third region ( 3 ) of the display panel  110 , and thus, the transfer of a sound from the first region ( 1 ) to the second region ( 2 ) may be blocked or reduced and the transfer of a sound from the second region ( 2 ) to the first region ( 1 ) may be blocked or reduced. Accordingly, a degradation in sound quality caused by interference of sounds generated in the first region ( 1 ) and the second region ( 2 ) may be reduced, and a sound characteristic of the middle-pitched sound band and the high-pitched sound band may be more enhanced. 
     Therefore, the display apparatus according to an embodiment of the present disclosure may include five vibration devices and may be configured with a plurality of vibration devices including an upper channel or a height channel and a main channel, thereby providing a display apparatus including five channels. Also, the five vibration devices may be independently supplied with and driven by a sound signal, and thus, each of the five vibration devices may reproduce an independent sound channel. 
     According to some embodiments of the present disclosure, the third vibration device  500 L and the fourth vibration device  500 R may be configured as the same vibration device, for the left-right symmetricity of a sound. For example, the third vibration device  500 L and the fourth vibration device  500 R may be configured as a coil type vibration device. The coil type vibration device may be the vibration device described above with reference to  FIGS.  1  to  5 E . For example, one or more of the first vibration device  600 HL and the second vibration device  600 HR may be configured as a vibration device which is the same as one or more of the third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C. The first vibration device  600 HL and the second vibration device  600 HR may be configured as a film type vibration device. The fifth vibration device  500 C may be configured as a vibration device which is the same as the first vibration device  600 HL and the second vibration device  600 HR. For example, the fifth vibration device  500 C may be configured as the coil type vibration device. For example, the first to fifth vibration devices  600 HL to  500 C may be configured as two or more different vibration devices. Accordingly, a display apparatus for realizing a 3.2.2-channel may be implemented. 
     With reference to  FIGS.  9 A and  9 B , a size of one or more among a first partition  1711  and a second partition  1712  may be configured to differ from one or more among a third partition  1721  and a fourth partition  1722 . A size of one or more among a fifth partition  1731  and a sixth partition  1732  may be configured to differ from one or more among the first partition  1711  and the second partition  1712 . For example, a length of one or more among the first partition  1711  and the second partition  1712  may be configured to differ from one or more among the third partition  1721  and the fourth partition  1722 . For example, a length of one or more among the fifth partition  1731  and the sixth partition  1732  may be configured to differ from one or more among the first partition  1711  and the second partition  1712 . Therefore, the first vibration device  600 HL and the second vibration device  600 HR may output a sound band of 300 Hz or more, and the third vibration device  500 L, the fourth vibration device  500 R, and the fifth vibration device  500 C may output a sound band of a full range. Descriptions of the partitions and the first to sixth regions ( 1 ) to ( 6 ) may be the same as descriptions given above with reference to  FIGS.  8 A and  8 B , and thus, repetitive descriptions are omitted. 
     Therefore, according to an embodiment of the present disclosure, sizes of partitions near a vibration device may be differently adjusted, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or more and/or a sound band of a full range. 
       FIGS.  10 A to  10 F  illustrate a display apparatus including a vibration device according to another embodiment of the present disclosure. 
       FIGS.  10 A to  10 D  will be described below with reference to the display apparatus of  FIG.  6 A  for example, and the display apparatus of  FIGS.  6 B to  7 D  may also be identically applied thereto.  FIGS.  10 E and  10 F  will be described below with reference to the display apparatus of  FIG.  8 A  for example, and the display apparatus of  FIGS.  8 B to  9 B  may also be identically applied thereto. 
     A sound wave which is generated when a display device  100  (for example, a display panel  110 ) vibrates by a vibration device  500  may be spread radially from a center of a vibration device and may travel. The sound wave may be referred to as a progressive wave. The progressive wave may be reflected at one side of a partition to generate a reflected wave, and the reflected wave may travel in a direction opposite to the progressive wave. The reflected wave overlaps and interferes with the progressive wave and does not travel, thereby generating a standing wave that stands at a certain position. A sound pressure is reduced by the standing wave, and for this reason, a sound output characteristic is deteriorated. 
     When a partition is provided at the display device  100 , it is unable to control a peak or dip phenomenon caused by a standing wave. The peak phenomenon may be a phenomenon where a sound pressure level bounces in a specific frequency, and the dip phenomenon may be a phenomenon where generating of a specific frequency is suppressed, and thus, a low sound pressure is generated. A sound output characteristic of the vibration device  500  may be reduced by the peak or dip phenomenon. A structure for controlling the peak or dip phenomenon is not simply implemented but has been implemented through various experiments. Therefore, the pad portion may be provided at the partition so as to decrease the peak or dip phenomenon that are caused by a standing wave occurring in a lengthwise direction of the vibration device. The phenomenon of sound pressure reduction caused by the standing wave generated by interference between the reflected wave and the progressive wave may be reduced by the pad portion. However, a phenomenon may occur where a shape of the partition swells to a screen of the display device  100  (for example, the display panel  110 ) due to a shape of the pad portion, and there may occur a problem where the display panel is recognized unevenly because the display device or the display panel is not flat or a supporting member is not flat. Such a phenomenon may be an uneven phenomenon or a wave phenomenon (hereinafter referred to as a wave phenomenon) of the display device  100  (for example, the display panel  110 ) or the supporting member  300 , but embodiments of the present disclosure are not limited thereto. Therefore, the partition should be implemented to prevent the wave phenomenon and to easily control the peak or dip phenomenon caused by a standing wave. Accordingly, the inventors have performed various experiments on a shape of the partition. Through the various experiments, the inventors have recognized that the partition should be disposed based on a shape of the display device  100  (for example, the display panel  110 ). For example, the partition may have a tetragonal shape, but is not limited thereto and a shape of the partition may be changed based on a shape or a perimeter shape of the display panel  110 . When the display device  100  (for example, the display panel  110 ) is a curved display panel device or a curve display panel device having a curve shape or the like, the partition may have a curved shape or a curve shape. Therefore, because the partition is disposed along a shape or a perimeter shape of the display device  100  (for example, the display panel  110 ), the attraction of the display device  100  (for example, the display panel  110 ) may decrease in a process of attaching the supporting member  300  on the display device  100  (for example, the display panel  110 ), and thus, the wave phenomenon may be prevented. 
     A shape of the pad portion may be configured to prevent the wave phenomenon from occurring when the display device  100  is pulled in a process of attaching to the supporting member by the pad portion at the supporting member. Alternatively, a shape of the pad portion may be configured to prevent the wave phenomenon from occurring when the display device  100  is pulled in a process of attaching to the supporting member by the pad portion at the display panel. For example, the pad portion should be implemented to easily control the peak or dip phenomenon caused by a standing wave of the vibration device and to prevent the wave phenomenon. In the following embodiments, an example where a partition is disposed at a supporting member will be described, and the embodiments of the present disclosure are not limited thereto, and the partition may be disposed at a rear surface of a display panel. To illustrate a vibration device and a partition, an example where the partition is disposed at a supporting member will be described. For example, when the partition is disposed at the supporting member, an adverse influence of image quality of the display panel caused by the partition disposed at the display panel may be reduced. 
     With reference to  FIGS.  10 A to  10 F , a standing wave causing a reduction in a sound pressure level may much occur at a point at which a magnitude of a progressive wave and a reflected wave is large. Therefore, the pad portion may be disposed at a position at which a sound wave transferred from a vibration device is largest. For example, the pad portion may be disposed at one or more sides, to which a strongest sound wave is transferred, among four sides of a partition and may be implemented toward the vibration device. 
     With reference to  FIGS.  10 A and  10 B , one or more pad portions may be disposed at one or more sides of the first partition  1711 . For example, a 1-1 st  pad portion  721  and a 1-2 nd  pad portion  722  may be disposed at one or more sides of the first partition  1711 . For example, the 1-1 st  pad portion  721  and the 1-2 nd  pad portion  722  may be disposed toward a first vibration device  500 HL. The 1-1 st  pad portion  721  and the 1-2 nd  pad portion  722  may be configured as one body or a single body, but embodiments of the present disclosure are not limited thereto. For example, one or more among the 1-1 st  pad portion  721  and the 1-2 nd  pad portion  722  may be configured as two or more elements. One or more pad portions may be further disposed at a side facing a side on which the 1-1 st  pad portion  721  and the 1-2 nd  pad portion  722  are disposed. For example, a 1-3 rd  pad portion  723  and a 1-4 th  pad portion  724  may be further disposed at a side facing the side on which the 1-1 st  pad portion  721  and the 1-2 nd  pad portion  722  are disposed. The 1-3 rd  pad portion  723  and the 1-4 th  pad portion  724  may be disposed toward the first vibration device  500 HL. The 1-3 rd  pad portion  723  and the 1-4 th  pad portion  724  may be configured as one body or a single body, but embodiments of the present disclosure are not limited thereto. For example, one or more among the 1-3 rd  pad portion  723  and the 1-4 th  pad portion  724  may be configured as two or more elements. The 1-1 st  to 1-4 th  pad portions  721  to  724  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto.

For example, a 2-1 st  pad portion  821  and a 2-2 nd  pad portion  822  may be disposed at one or more sides of the second partition  1712 . For example, the 2-1 st  pad portion  821  and the 2-2 nd  pad portion  822  may be disposed toward a second vibration device  500 HR. The 2-1 st  pad portion  821  and the 2-2 nd  pad portion  822  may be configured as one body or a single body, but embodiments of the present disclosure are not limited thereto. For example, one or more among the 2-1 st  pad portion  821  and the 2-2 nd  pad portion  822  may be configured as two or more elements. One or more pad portions may be further disposed at a side facing a side on which the 2-1 st  pad portion  821  and the 2-2 nd  pad portion  822  are disposed.

For example, the 5-1 st  to 5-6 th  pad portions  911  to  916  may be disposed at the sixth region ( 6 ) and may be disposed toward the fifth vibration device  500 C. Because the 5-5 th  pad portion  915  and the 5-6 th  pad portion  916  are further provided, a reduction in a sound wave caused by a standing wave may more decrease, and a sound output characteristic of a vibration device may be more enhanced. 
     With reference to  FIG.  10 C , the display apparatus according to some embodiments of the present disclosure may further include one or more bent portions at one or more sides of a partition. The bent portion may be disposed to decrease a reduction in a sound wave caused by a standing wave which occurs due to interference of a reflected wave and a progressive wave. The bent portion may be disposed at one or more sides, to which a strongest sound wave is transferred, of four sides of the partition and may be configured toward a vibration device. The other elements may be the same as or similar to the elements described above with reference to  FIGS.  10 A and  10 B , and thus, their repetitive descriptions may be omitted or will be briefly given. 
     One or more bent portions may be further provided at one or more sides of a fifth partition  1731  toward one or more vibration device. For example, a first bent portion  701  may be provided at one or more sides of the fifth partition  1731  toward a third vibration device W 1 .

     A bent portion may have an open structure at a center portion of a vibration device. However, embodiments of the present disclosure are not limited thereto, and the bent portion may have a V-shaped closed structure at the center portion of the vibration device. When the bent portion has the open structure at the center portion of the vibration device, the material cost may be reduced compared to the closed structure. According to a sound characteristic experiment, when the bent portion has the open structure at the center portion of the vibration device, compared with a case where the bent portion has the closed structure at the center portion of the vibration device, the inventors have confirmed that a sound characteristic difference is very small or there is no sound characteristic difference. Accordingly, because one or more bent portions are provided at one or more among the fifth and sixth partitions  1731  and  1732 , a reduction in a sound wave caused by a standing wave of the vibration device may decrease. 
     With reference to  FIGS.  10 A to  10 D , a seventh partition  1750  described above with reference to  FIGS.  6 B and  7 B  may be applied. When the seventh partition  1750  is applied, the pad portion described above with reference to  FIGS.  10 A to  10 D  may be provided at one or more sides of the seventh partition  1750 . This will be described with reference to  FIG.  10 A , and the description of  FIG.  10 A  may be applied to  FIGS.  10 B to  10 D . For example, a 1-3 rd  pad portion  723  and a 1-4th pad portion  724  may be disposed at one or more sides of the seventh partition  1750 . The 1-3 rd  pad portion  723  and the 1-4 th  pad portion  724  may be disposed toward a first vibration device  500 HL. For example, a 2-3 rd  pad portion  823  and a 2-4th pad portion  824  may be disposed at one or more sides of the seventh partition  1750 . The 2-3 rd  pad portion  823  and the 2-4 th  pad portion  824  may be disposed toward a second vibration device  500 HR. For example, a 2-3 re  pad portion  823  and a 2-4 th  pad portion  824  may be disposed at one or more sides of the seventh partition  1750 . The 2-3 rd  pad portion  823  and the 2-4 th  pad portion  824  may be disposed toward a second vibration device  500 HR. For example, a 3-3 rd  pad portion  713  and a 3-4 th  pad portion  714  may be disposed at one or more sides of the seventh partition  1750 . The 3-3 rd  pad portion  713  and the 3-4 th  pad portion  714  may be disposed toward a third vibration device W 1 .

The 4-3 rd  pad portion  813  and the 4-4 th  pad portion  814  may be disposed toward a fourth vibration device W 2 . 
     With reference to  FIGS.  10 E and  10 F , an eighth partition  7211  may be further provided near a first vibration device  600 HL. The eighth partition  7211  may be configured to be smaller than or equal to a size of a first partition  1711  and/or a fifth partition  1731  as described above with reference to  FIGS.  8 A to  9 B . For example, the eighth partition  7211  may be disposed to surround the first vibration device  600 HL. The eighth partition  7211  may surround the first vibration device  600 HL along with the first partition  1711  and/or the fifth partition  1731 , and thus, a vibration space of the first vibration device  600 HL may be secured, thereby increasing a sound pressure level characteristic. Also, the eighth partition  7211  may prevent a sound or a sound pressure level from being leaked to the outside through a side surface between a display device  100  and a supporting member  300 , and thus, a sound output characteristic of a display apparatus may be more enhanced. The eighth partition  7211  may have a tetragonal shape which surrounds the first vibration device  600 HL. However, embodiments of the present disclosure are not limited thereto, and the eighth partition  7211  may have a shape which is the same as or different from a whole shape of the first vibration device  600 HL. For example, when the first vibration device  600 HL has a square shape, the eighth partition  7211  may have a square shape, a circular shape, or an oval shape which is relatively greater in size than the first vibration device  600 HL. The eighth partition  7211  may limit (or define) a vibration region (or a vibration area) of the display device  100  (for example, a display panel  110 ) based on the first vibration device  600 HL. For example, as a size of the eighth partition  7211  increases, a vibration region of a first region ( 1 ) may increase, and thus, a sound characteristic of a low-pitched sound band of a left sound may be enhanced. 
     For example, the first vibration device  600 HL may be configured to be disposed on the same plane as the third vibration device W 1 . For example, the first vibration device  600 HL may be configured to be disposed on the same plane as the third vibration device W 1  in the lengthwise direction of the display device  100 . Based on this configuration, a sense of sound field output from the first vibration device  600 HL and the third vibration device W 1  may be maximized, thereby providing a display apparatus with an enhanced sense of sound field. 
     A ninth partition  7212  may be further provided near a first vibration device  600 HL. The ninth partition  7212  may be configured to be smaller than or equal to a size of a second partition  1712  and/or a fifth partition  1731  as described above with reference to  FIGS.  8 A to  9 B . For example, the ninth partition  7212  may be disposed to surround the second vibration device  600 HR. The ninth partition  7212  may surround the second vibration device  600 HR along with the second partition  1712  and/or the fifth partition  1731 , and thus, a vibration space of the second vibration device  600 HR may be secured, thereby increasing a sound pressure level characteristic. Also, the ninth partition  7212  may prevent a sound or a sound pressure level from being leaked to the outside through a side surface between a display device  100  and a supporting member  300 , and thus, a sound output characteristic of a display apparatus may be more enhanced. The ninth partition  7212  may have a tetragonal shape which surrounds the second vibration device  600 HR. However, embodiments of the present disclosure are not limited thereto, and the ninth partition  7212  may have a shape which is the same as or different from a whole shape of the second vibration device  600 HR. For example, when the second vibration device  600 HR has a square shape, the ninth partition  7212  may have a square shape, a circular shape, or an oval shape which is relatively greater in size than the second vibration device  600 HR. The ninth partition  7212  may limit (or define) a vibration region (or a vibration area) of the display device  100  (for example, a display panel  110 ) based on the second vibration device  600 HR. For example, as a size of the ninth partition  7212  increases, a vibration region of a second region ( 2 ) may increase, and thus, a sound characteristic of a low-pitched sound band of a right sound may be enhanced. 
     For example, the second vibration device  600 HR may be configured to be disposed on the same plane as the fourth vibration device W 2 . For example, the second vibration device  600 HR may be configured to be disposed on the same plane as the fourth vibration device W 2  in the lengthwise direction of the display device  100 . Based on this configuration, a sense of sound field output from the second vibration device  600 HR and the fourth vibration device W 2  may be maximized, thereby providing a display apparatus with an enhanced sense of sound field. 
     The eighth and ninth partitions  7211  and  7212  may include one or more among a double-sided tape, a double-sided foam tape, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided foam pad, an adhesive, and a bond, but embodiments of the present disclosure are not limited thereto. When the fifteenth to twentieth partitions  7211  to  7216  is configured with a double-sided tape or a double-sided foam pad, an adhesive force may be enhanced in a process of attaching a rear surface of the display device  100  on an upper surface of the supporting member  300 . For example, the eighth and ninth partitions  7211  and  7212  may include a material having elasticity which enables a certain degree of compression. For example, the eighth and ninth partitions  7211  and  7212  may include polyurethane, polyolefin, or polyethylene, but embodiments of the present disclosure are not limited thereto.

The magnet  1620  may share the first vibration generating part  1801  and the second vibration generating part  1802 . For example, a bobbin  1650   a  of the first vibration generating part  1801  and a coil  1660   a  near the bobbin  1650   a  may be disposed near the magnet  1620 . For example, a second bobbin  1650   b  of the second vibration generating part  1802  and a second coil  1660   b  near the second bobbin  1650   b  may be disposed near the magnet  1620 . For example, the lower frame  1610   a  and a plate  1611  may be respectively disposed at a lower portion and an upper portion of the magnet  1620 , and may increase a magnetic flux density generated through the magnet  1620 , the coil  1660   a , and the second coil  1660   b , thereby enhancing a vibration characteristic. The lower frame  1610   a  may be a yoke, but embodiments of the present disclosure are not limited thereto. 
     The side frame  1610   b  may be connected or coupled to the lower frame  1610   a , and may include at least one hole  217  to output a sound or a vibration. For example, the hole  217  may a vent hole. For example, the hole  217  may output sound of a low-pitched sound band, generated by a vibration plate  214   b  of the second vibration generating part  1802  in an air gap inside of the vibration device  1800 , to a rearward region behind a display panel  110 . 
     The side frame  1610   b  may include a conductive material, and may control a magnetic flux generated by the magnet  1620 . For example, the side frame  1610   b  may surround the magnet  1620  with being spaced apart therefrom, and thus, may allow a magnetic flux generated by the magnet  1620  to concentrate on the inside of the second bobbin  1650   b , thereby preventing a leakage magnetic flux. The side frame  1610   b  may be a yoke, but embodiments of the present disclosure are not limited thereto. The hole  217  may be provided in the side frame  1610   b , and moreover, may be provided in the lower frame  1610   a  and may be provided in a region connected to the side frame  1610   b  and the lower frame  1610   a . The side frame  1610   b  may be connected to a rear cover by a connection member  1710  such as a nut or bolt, or may be disposed between the display panel. 
     The first vibration generating part  1801  may include the magnet  1620  disposed on the frame, the bobbin  1650   a  near the magnet  1620 , and a coil  1660   a  and a damper  1670   a  near the bobbin  1650   a . For example, their descriptions are similar to descriptions given above with reference to  FIGS.  2  to  5 E , and thus, their repetitive descriptions may be omitted or will be briefly given. 
     The magnet  1620  may be disposed on the lower frame  1610   a . For example, the magnet  1620  may be disposed between a plate  1611  and the lower frame  1610   a . The lower frame  1610   a  and the plate  1611  may control a magnetic flux generated by the magnet  1620 . For example, the magnet  1620  may be surrounded by the lower frame  1610   a  and the plate  1611 , and thus, the magnetic flux generated by the magnet  1620  may concentrate on the inside of the bobbin  1650   a  and may be controlled. 
     The bobbin  1650   a  may be attached at a rear surface of a bobbin ring  1652   a . For example, when a sound generating current (or a vibration generating current) is applied to the coil  1660   a  wound around an outer circumference surface of the bobbin  1650   a  and thus a magnetic field is generated in the first vibration generating part  1801 , the display device, for example, the display panel may vibrate based on the magnetic field by the bobbin ring  1652   a . The bobbin ring  1652   a  may be between the bobbin  1650   a  and the display panel, and may transfer a vibration of the bobbin  1650   a  to the display panel. The first vibration generating part  1801  may output a sound of a middle-high-pitched sound band. 
     The second vibration generating part  1802  may include the magnet  1620  disposed on the frame, the plate  1611  on the magnet  1620 , the second bobbin  1650   b  near the magnet  1620 , and a second coil  1660   b  and a second damper  1670   b  near the second bobbin  1650   b.    
     A vibration plate  214   b  may be disposed on the second bobbin  1650   b . For example, the vibration plate  214   b  may be spaced apart from the rear surface of the display panel, and may prevent heat occurring in the second bobbin  1650   b  from being transferred to the display panel. 
     When the sound generating current (or a vibration generating current) is applied to the second coil  1660   b  wound around an outer circumference surface of the second bobbin  1650   b  and thus a magnetic field is generated in the second vibration generating part  1802 , the second bobbin  1650   b  may vibrate an air layer or an air gap of a vibration plate peripheral portion by the vibration plate  214   b  based on the magnetic field to output a sound. For example, a front surface of the second bobbin  1650   b  may contact the vibration plate  214   b , and may vibrate the vibration plate  214   b  based on a state where a current is applied thereto or not. The second vibration generating part  1802  may output sound to a forward region and a rearward region with respect to the vibration plate  214   b . For example, the second vibration generating part  1802  may output a sound of a low-pitched sound band. For example, a sound generated by the vibration plate  214   b  of the second vibration generating part  1802  may include a first low-pitched sound propagated to an upper portion of the vibration plate  214   b  and a second low-pitched sound propagated to a lower portion of the vibration plate  214   b . For example, the second vibration generating part  1802  may be a woofer, but embodiments of the present disclosure are not limited thereto. 
     The magnet  1620  may be disposed on the lower frame  1610   a . The plate  1611  may be spaced apart from the vibration plate  214   b . The second bobbin  1650   b  may be disposed on a rear surface of the vibration plate  214   b . For example, the second bobbin  1650   b  may surround the magnet  1620  and the plate  1611 . 
     The second damper  1670   b  may be disposed between the first vibration generating part  1801  and the second vibration generating part  1802 . For example, the second damper  1670   b  may be disposed between the damper  1670   a  of the first vibration generating part  1801  and the second bobbin  1650   b  of the second vibration generating part  1802 . For example, the second damper  1670   b  may be disposed between the first vibration generating part  1801  and the vibration plate  214   b  of the second vibration generating part  1802 . The vibration plate  214   b  may not physically contact the first vibration generating part  1801 . For example, the second damper  1670   b  may prevent sound interference between the first vibration generating part  1801  and the second vibration generating part  1802 . An edge  1670   c  may be disposed on the vibration plate  214   b . The edge  1670   c  may prevent deformation such as distortion of the vibration plate  214   b  when the vibration plate  214   b  performs a vertical motion, and thus, may provide clean sound quality and may enhance the reliability of the vibration device  1800 . The second damper  1670   b  may be a first suspension, and the edge  1670   c  may be a second suspension, but embodiments of the present disclosure are not limited thereto. 
     The magnet  1620  of the first vibration generating part  1801  and the magnet  1620  of the second vibration generating part  1802  may have magnetic fields in opposite directions. The first vibration generating part  1801  may vibrate (or directly vibrate) the display panel to output sound of a high-pitched sound band to a forward region in front of the display panel, and the second vibration generating part  1802  may output sound of a low-pitched sound band to a rearward region behind the display panel. Accordingly, because the first vibration generating part  1801  and the second vibration generating part  1802  have the magnetic fields in opposite directions, a vibration of the first vibration generating part  1801  and the second vibration generating part  1802  may be independently driven or controlled. 
     Therefore, the woofer-integrated vibration device may include a woofer disposed near the vibration device. The vibration device may be disposed on the rear surface of the display panel and may generate a sound of a middle-high-pitched sound band, and the woofer may be spaced apart from the rear surface of the display panel and may perform a vertical vibration to generate a sound of a low-pitched sound band. For example, the vibration device and the woofer may be driven based on different sound signals or voice signals applied thereto. Accordingly, the sound of the low-pitched sound band may be enhanced by the woofer-integrated vibration device. 
     To provide a sound in a display apparatus, a speaker may be implemented as a film type in a case which implements the speaker, and thus, a thickness of the display apparatus may be configured to be thin. A film type vibration device may be manufactured to have a large area, and thus, may be applied to a large-area display apparatus. However, the film type vibration device may be low in piezoelectric characteristic, and thus, due to a low vibration, there may be a problem where it is difficult to apply the film type vibration device to the large-area display apparatus. When the film type vibration device is implemented by applying ceramic so as to enhance a piezoelectric characteristic, there may be a problem where durability is weak and a size of ceramic is limited. 
     When a vibration device including a piezoelectric composite including piezoelectric ceramic is applied to a display apparatus, the piezoelectric composite may vibrate in a lateral direction with respect to a widthwise direction (for example, in a lateral direction with respect to a widthwise direction of the display apparatus), and thus, it may be unable to sufficiently vibrate the display apparatus in an upward-downward (or forward-rearward) direction, whereby it may be difficult to apply the vibration device to the display apparatus and it may be unable to output a desired sound in a forward direction of the display apparatus. In a case where a film type piezoelectric element is applied to a display apparatus, there may be a problem where a sound pressure level characteristic is low compared to a speaker such as an exciter. In a case where a stack type piezoelectric element, where a plurality of films including a film type piezoelectric element formed of a plurality of layers are stacked, is applied to a display apparatus so as to improve a sound pressure level, there may be a problem where power consumption increases and a thickness of the display apparatus is thickened. Also, in a case where one vibration device is disposed on a rear surface of a display panel (for example, a mobile display apparatus), the inventors have recognized that a mono sound is output, but there is a problem where it is difficult to output a multi-channel sound. Therefore, a vibration device may be further disposed at a periphery of a display panel so as to implement a multi-channel sound, but it may be difficult to place an exciter in a flexible display apparatus where a curve portion is provided at the display panel. Also, in a case where a speaker including piezoelectric ceramic is provided, there may be a problem where piezoelectric ceramic is easily broken. According to an embodiment of the present disclosure, a vibration device applicable to a display apparatus which realizes a sound characteristic of a multichannel and includes the flexible display apparatus may be provided. This will be described below with reference to  FIGS.  12  to  17   . 
       FIG.  12    illustrates a vibration device according to other embodiment of the present disclosure. 
     With reference to  FIG.  12   , the vibration device  450  according to an embodiment of the present disclosure may include a piezoelectric vibration portion  451 , a first electrode portion E 1 , and a second electrode portion E 2 . 
     The piezoelectric vibration portion  451  may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the piezoelectric material may have a characteristic where pressure or twisting (or bending) is applied to a crystalline structure by an external force, a potential difference occurs due to dielectric polarization caused by a relative position change of a positive (+) ion and a negative (−) ion, and a vibration is generated by an electric field based on a voltage applied thereto. The piezoelectric vibration portion  451  may be referred to as a vibration layer, a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a vibration portion, a piezoelectric material portion, an electroactive portion, a piezoelectric structure, an inorganic material layer, or an inorganic material portion, but embodiments of the present disclosure are not limited thereto. 
     The piezoelectric vibration portion  451  may be formed of a transparent, semitransparent, or opaque piezoelectric material (or an electroactive material), and may be transparent, semitransparent, or opaque. The piezoelectric vibration portion  451  may be formed of a ceramic-based material for generating a relatively high vibration, or may be formed of piezoelectric ceramic having a perovskite-based crystalline structure. The perovskite crystalline structure may have a piezoelectric effect and an inverse piezoelectric effect and may be a plate-shaped structure having orientation. The perovskite crystalline structure may be represented by a chemical formula “ABO 3 ”. Here, A may include a divalent metal element, and B may include a tetravalent metal element. For example, in the chemical formula “ABO 3 ”, A and B may be cations, and O may be anions. For example, the perovskite crystalline structure may include at least one or more of PbTiO 3 , PbZrO 3 , PbZrTiO 3 , BaTiO 3 , and SrTiO 3 , but embodiments of the present disclosure are not limited thereto. 
     The piezoelectric vibration portion  451  according to an embodiment of the present disclosure may include a lead zirconate titanate (PZT)-based material including lead (Pb), zirconium (Zr), and titanium (Ti) or may include a lead zirconate nickel niobate (PZNN)-based material including lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), but embodiments of the present disclosure are not limited thereto. Also, the piezoelectric vibration portion  451  may include at least one or more of CaTiO 3 , BaTiO 3 , and SrTiO 3  without Pb, but embodiments of the present disclosure are not limited thereto. 
     The piezoelectric vibration portion  451  according to an embodiment of the present disclosure may be configured in a circular shape, an ellipse shape, or a polygonal shape, but embodiments of the present disclosure are not limited thereto. 
     The first electrode portion E 1  may be disposed at a first surface (or a top surface or an upper surface or a front surface) of the piezoelectric vibration portion  451 , and electrically connected to the first surface of the piezoelectric vibration portion  451 . For example, the first electrode portion E 1  may have a single-body electrode type which is disposed at a whole first surface of the piezoelectric vibration portion  451 . For example, the first electrode portion may have the same shape as the piezoelectric vibration portion  451 , but embodiments of the present disclosure are not limited thereto. The first electrode portion E 1  according to an embodiment of the present disclosure may be formed of a transparent conductive material, a semitransparent conductive material, or an opaque conductive material. For example, examples of the transparent conductive material or the semitransparent conductive material may include indium tin oxide (ITO) or indium zinc oxide (IZO), but embodiments of the present disclosure are not limited thereto. Examples of the opaque conductive material may include aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), and Mg or an alloy thereof, but embodiments of the present disclosure are not limited thereto. 
     The second electrode portion E 2  may be disposed at a second surface (or a bottom surface or a lower surface or a rear surface), which is opposite to the first surface, of the piezoelectric vibration portion  451 , and electrically connected to the second surface of the piezoelectric vibration portion  451 . For example, the second electrode portion E 2  may have a single-body electrode type which is disposed at a whole second surface of the piezoelectric vibration portion  451 . For example, the second electrode portion E 2  may have a larger size than that of the piezoelectric vibration portion  451 , and may have the same shape as the piezoelectric vibration portion  451 , but embodiments of the present disclosure are not limited thereto. The second electrode portion E 2  according to an embodiment of the present disclosure may be formed of a transparent conductive material, a semitransparent conductive material, or an opaque conductive material. For example, the second electrode portion E 2  may be formed of the same material as the first electrode portion E 1 , but embodiments of the present disclosure are not limited thereto. In another example, the second electrode portion E 2  may be formed of a different material than the first electrode portion E 1 . 
     The piezoelectric vibration portion  451  may be polarized (or poling) by a certain voltage applied to the first electrode portion E 1  and the second electrode portion E 2  in a certain temperature atmosphere, or a temperature atmosphere that may be changed from a high temperature to a room temperature. Embodiments of the present disclosure are not limited to these examples. The piezoelectric vibration portion  451  may vibrate by alternately and/or repeatedly contract and expand based on a piezoelectric effect (or a piezoelectric characteristic) according to a sound signal (or a voice signal) applied to the first electrode portion E 1  and the second electrode portion E 2  from the outside. 
     The vibration device  450  according to an embodiment of the present disclosure may further include a first protection member and a second protection member. 
     The first protection member may be disposed at the first electrode portion E 1  and protect the first electrode portion E 1 . For example, the first protection member may be formed of a plastic material, a fiber material, or wood material, but embodiments of the present disclosure are not limited thereto. 
     The second protection member may be disposed at the second electrode portion E 2  and protect the second electrode portion E 2 . For example, the second protection member may be formed of a plastic material, a fiber material, or wood material, but embodiments of the present disclosure are not limited thereto. For example, the first protection member may be formed of the same or different material as the second protection member. Any one of the first protection member and the second protection member may be attached to or coupled to the display panel via an adhesive member. 
       FIG.  13    illustrates a vibration device according to other embodiment of the present disclosure. 
     With reference to  FIG.  13   , the vibration device  450  according to other embodiment of the present disclosure may be referred to as a flexible sound generator, a flexible actuator, a flexible speaker, a flexible piezoelectric speaker, a film actuator, a film piezoelectric composite actuator, a film speaker, a film piezoelectric speaker, or film piezoelectric composite speaker, but embodiments of the present disclosure are not limited thereto. 
     The vibration device  450  according to an embodiment of the present disclosure may include a piezoelectric vibration portion  453 , a first electrode portion E 1 , and a second electrode portion E 2 . 
     The piezoelectric vibration portion  453  may include a piezoelectric material, a composite piezoelectric material, or an electroactive material, and the piezoelectric material, the composite piezoelectric material and the electroactive material may have a piezoelectric effect. The piezoelectric vibration portion  453  may be referred to as a vibration layer, a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a vibration portion, a piezoelectric material portion, an electroactive portion, a piezoelectric structure, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, but embodiments of the present disclosure are not limited thereto. The piezoelectric vibration portion  453  may be formed of a transparent, semitransparent, or opaque piezoelectric material, and may be transparent, semitransparent, or opaque. 
     The piezoelectric vibration portion  453  according to an embodiment of the present disclosure may include a plurality of first portions  453   a  and a plurality of second portions  453   b . For example, the plurality of first portions  453   a  and the plurality of second portions  453   b  may be alternately and repeatedly arranged in a first direction X (or a second direction Y). For example, the first direction X may be a widthwise direction or a first horizontal direction of the piezoelectric vibration portion  453 . The second direction Y may be a lengthwise direction or a second horizontal direction of the piezoelectric vibration portion  453 . An embodiment of the present disclosure is not limited thereto, and the first direction X may be the lengthwise direction or the second horizontal direction of the piezoelectric vibration portion  453 , and the second direction Y may be the widthwise direction or the first horizontal direction of the piezoelectric vibration portion  453 . 
     Each of the plurality of first portions  453   a  may be configured as an inorganic material portion. The inorganic material portion may include the above-described piezoelectric material. For example, each of the plurality of first portions  453   a  may include a piezoelectric material which is be substantially the same as the piezoelectric vibration portion  453  described above with reference to  FIG.  12   , and thus, their repetitive descriptions may be omitted. 
     Each of the plurality of first portions  453   a  according to an embodiment of the present disclosure may be disposed between the plurality of second portions  453   b . For example, the plurality of first portions  453   a  may have a first width W 1  parallel to the first direction X (or the second direction Y) and a length parallel to the second direction Y (or the first direction X). Each of the plurality of second portions  453   b  may have a second width W 2  parallel to the first direction X (or the second direction Y) and may have a length parallel to the second direction Y (or the first direction X). The first width W 1  may be the same as or different from the second width W 2 . For example, the first width W 1  may be greater than the second width W 2 . For example, the first portion  453   a  and the second portion  453   b  may include a line shape or a stripe shape which has the same size or different sizes. Therefore, the piezoelectric vibration portion  453  may include a 2-2 composite structure and thus may have a resonance frequency of 20 kHz or less, but embodiments are not limited thereto and a resonance frequency of the piezoelectric vibration portion  453  may vary based on one or more of a shape, a length, and a thickness. 
     In the piezoelectric vibration portion  453 , each of the plurality of first portions  453   a  and the plurality of second portions  453   b  may be disposed (or arranged) at the same plane (or the same layer) in parallel. Each of the plurality of second portions  453   b  may be connected or attached to a second portion  453   b  adjacent thereto. For example, each of the plurality of second portions  453   b  may be configured to fill a gap between two adjacent first portions of the plurality of first portions  453   a  and may be connected or attached to a second portion  453   b  adjacent thereto. The piezoelectric vibration portion  453  may extend by a desired size or length based on the side coupling (or connection) of the first portion  453   a  and the second portion  453   b.    
     In the piezoelectric vibration portion  453 , a width (or a size) W 2  of each of the plurality of second portions  453   b  may progressively decrease in a direction from a center portion to both peripheries (or both ends) of the piezoelectric vibration portion  453  or the vibration device  450 . 
     According to an embodiment of the present disclosure, a second portion  453   b , having a largest width W 2  among the plurality of second portions  453   b , may be located at a portion at which a highest stress may concentrate when the piezoelectric vibration portion  453  or the vibration device  450  is vibrating in a vertical direction Z (or a thickness direction). A second portion  453   b , having a smallest width W 2  among the plurality of second portions  453   b , may be located at a portion where a relatively low stress may occur when the piezoelectric vibration portion  453  or the vibration device  450  is vibrating in the vertical direction Z. For example, the second portion  453   b , having the largest width W 2  among the plurality of second portions  453   b , may be disposed at the center portion of the piezoelectric vibration portion  453 , and the second portion  453   b , having the smallest width W 2  among the plurality of second portions  453   b  may be disposed at the both edges or peripheries of the piezoelectric vibration portion  453 . Therefore, when the piezoelectric vibration portion  453  or the vibration device  450  is vibrating in the vertical direction Z, interference of a sound wave or overlapping of a resonance frequency, occurring in the portion on which the highest stress concentrates, may be reduced or minimized. Thus, dipping phenomenon of a sound pressure level occurring in the low-pitched sound band may be reduced, thereby improving flatness of a sound characteristic in the low-pitched sound band. For example, flatness of a sound characteristic may be a level of a deviation between a highest sound pressure and a lowest sound pressure. 
     In the piezoelectric vibration portion  453 , each of the plurality of first portions  453   a  may have different sizes (or widths). For example, a size (or a width) of each of the plurality of first portions  453   a  may progressively decrease or increase in a direction from the center portion to the both peripheries (or both ends) of the piezoelectric vibration portion  453  or the vibration device  450 . For example, in the piezoelectric vibration portion  453 , a sound pressure level characteristic of a sound may be enhanced and a sound reproduction band may increase, based on various natural vibration frequencies according to a vibration of each of the plurality of first portions  453   a  having different sizes. 
     Each of the plurality of second portions  453   b  may be disposed between the plurality of first portions  453   a . Therefore, in the piezoelectric vibration portion  453  or the vibration device  450 , vibration energy by a link in a unit lattice of the first portion  453   a  may increase by a corresponding second portion  453   b . Thus, a vibration may increase, and a piezoelectric characteristic and flexibility may be secured. For example, the second portion  453   b  may include at least one or more of an epoxy-based polymer, an acryl-based polymer, and a silicone-based polymer, but embodiments of the present disclosure are not limited thereto. 
     The plurality of second portions  453   b  according to an embodiment of the present disclosure may be configured as an organic material portion. For example, the organic material portion may be disposed between the inorganic material portions and may absorb an impact applied to the inorganic material portion (or the first portion), may release a stress concentrating on the inorganic material portion to enhance the total durability of the piezoelectric vibration portion  453  or the vibration device  450 , and may provide flexibility to the piezoelectric vibration portion  453  or the vibration device  450 . 
     The plurality of second portions  453   b  according to an embodiment of the present disclosure may have modulus and viscoelasticity that are lower than those of the first portion  453   a , and thus, the second portion  453   b  may enhance the reliability of the first portion  453   a  vulnerable to an impact due to a fragile characteristic. For example, the second portion  453   b  may include a material having a loss coefficient of about 0.01 to about 1.0 and modulus of about 0.1 [GPa] to about 10 [GPa]. 
     The organic material portion included in the second portion  453   b  may include one or more of an organic material, an organic polymer, an organic piezoelectric material, and an organic non-piezoelectric material that has a flexible characteristic in comparison with the inorganic material portion of the first portions  453   a . For example, the second portion  453   b  may be referred to as an adhesive portion, an elastic portion, a bending portion, a damping portion, or a flexible portion having flexibility, but embodiments of the present disclosure are not limited thereto. 
     The plurality of first portions  453   a  and the second portion  453   b  may be disposed on (or connected to) the same plane, and thus, the piezoelectric vibration portion  453  of the vibration array  210  according to various embodiments of the present disclosure may have a single thin film-type. For example, the piezoelectric vibration portion  453  may have a structure in which a plurality of first portions  453   a  is connected to one side of the piezoelectric vibration portion  453 . For example, the piezoelectric vibration portion  453  may have a structure in which a plurality of first portions  453   a  extends to one side of the piezoelectric vibration portion  453 . For example, the plurality of first portions  453   a  may have a structure connected to a whole the piezoelectric vibration portion  453 . For example, the plurality of first portions  453   a  may have a structure extended to a whole the piezoelectric vibration portion  453 . For example, the piezoelectric vibration portion  453  may be vibrated in a vertical direction (or a thickness direction) by the first portion  453   a  having a vibration characteristic and may be bent in a curved shape by the second portion  453   b  having flexibility. Also, in the piezoelectric vibration portion  453  according to various embodiments of the present disclosure, a size of the first portion  453   a  and a size of the second portion  453   b  may be adjusted based on a piezoelectric characteristic and flexibility needed for the piezoelectric vibration portion  453  or the vibration device  450 . For example, when the piezoelectric vibration portion  453  needs a piezoelectric characteristic rather than flexibility, a size of the first portion  453   a  may be adjusted to be greater than that of the second portion  453   b . As another example, when the piezoelectric vibration portion  453  needs flexibility rather than a piezoelectric characteristic, a size of the second portion  453   b  may be adjusted to be greater than that of the first portion  453   a . For example, the size of the second portion  453   b  and the size of the first portion  453   a  may be one or more of a width, a length, and a thickness. Accordingly, a size of the piezoelectric vibration portion  453  may be adjusted based on a characteristic needed therefor, and thus, the piezoelectric vibration portion  453  may be easy to design. 
     The first electrode portion E 1  may be disposed at a first surface (or an upper surface) of the piezoelectric vibration portion  453 . The first electrode portion E 1  may be disposed at or coupled to a first surface of each of a plurality of first portions  453   a  and a first surface of each of a plurality of second portions  453   b  in common and may be electrically connected to the first surface of each of the plurality of first portions  453   a . For example, the first electrode portion E 1  may be a single-body electrode type which is disposed at a whole first surface of the piezoelectric vibration portion  453 . For example, the first electrode portion E 1  may have the same shape as that of the piezoelectric vibration portion  453 , but embodiments of the present disclosure are not limited thereto. The first electrode portion E 1  according to an embodiment of the present disclosure, as described above with reference to  FIG.  12   , may include a transparent conductive material, a semitransparent conductive material, or an opaque conductive material.

The second electrode portion E 2  may be disposed at or coupled to a second surface of each of a plurality of first portions  453   a  and the second surface of each of a plurality of second portions  453   b  in common and may be electrically connected to a second surface of each of the plurality of first portions  453   a . For example, the second electrode portion E 2  may be a single-body electrode type which is disposed on a whole second surface of the piezoelectric vibration portion  453 . For example, the second electrode portion E 2  may have the same shape as that of the piezoelectric vibration portion  453 , but embodiments of the present disclosure are not limited thereto. The second electrode portion E 2  according to an embodiment of the present disclosure, as described above with reference to  FIG.  12   , may include a transparent conductive material, a semitransparent conductive material, or an opaque conductive material. 
     The piezoelectric vibration portion  453  may be polarized (or poling) by a certain voltage applied to the first electrode portion E 1  and the second electrode portion E 2  in a certain temperature atmosphere, or a temperature atmosphere that may be changed from a high temperature to a room temperature, but embodiments of the present disclosure are not limited thereto. For example, the piezoelectric vibration portion  453  may alternately and repeatedly contract and expand based on an inverse piezoelectric effect according to a sound signal (or voice signal) applied to the first electrode portion E 1  and the second electrode portion E 2  from the outside to vibrate. For example, the piezoelectric vibration portion  453  may vibrate based on a vertical-direction (or a thickness direction Z) vibration d 33  and a horizontal-direction (or a planar direction) vibration d 31  by the first electrode portion E 1  and the second electrode portion E 2 . The piezoelectric vibration portion  453  may increase the displacement of the display device by contraction and expansion in the horizontal-direction, thereby further improving the vibration.

For example, the vibration device  450  may include a plurality of inorganic material portion having a piezoelectric characteristic and an organic material portion connected between the plurality of inorganic material portion. 
     According to an embodiment of the present disclosure, any one of the first electrode portion E 1  and the second electrode portion E 2  may be attached or coupled to the display device by an adhesive member. 
     The vibration device  450  according to an embodiment of the present disclosure may further include a first protection member and a second protection member.

For example, the first protection member may include a material which is the same as or different from that of the second protection member. Any one of the first protection member and the second protection member may be attached or coupled to the display device by an adhesive member.

For example, each of the plurality of first portions  453   a  may have a hexahedral shape (or a six-sided object shape) having the same size and may be disposed in a lattice shape. For example, each of the plurality of first portions  453   a  may include a piezoelectric material which is be substantially the same as the first portion  453   a  described above with reference to  FIG.  13   , and thus, like reference numerals refer to like elements and their repetitive descriptions may be omitted.

The second portion  453   b  may be configured to fill a gap or a space between two adjacent first portions  453   a  or to surround each of the plurality of first portions  453   a , and thus, may be connected or attached to an adjacent first portion  453   a . According to an embodiment of the present disclosure, a width of a second portion  453   b  disposed between two first portions  453   a  adjacent to each other along the first direction X may be the same as or different from that of the first portion  453   a , and a width of a second portion  453   b  disposed between two first portions  453   a  adjacent to each other along the second direction Y may be the same as or different from that of the first portion  453   a .

       FIG.  15    illustrates a vibration device according to other embodiment of the present disclosure and illustrates an embodiment where the piezoelectric vibration portion illustrated in  FIG.  13    is modified.

     With reference to  FIG.  15   , in the vibration device  450  according to another embodiment of the present disclosure, the piezoelectric vibration portion  453  according to an embodiment of the present disclosure may include a plurality of first portions  453   a , which are spaced apart from one another along a first direction X and a second direction Y, and a second portion  453   b  disposed between the plurality of first portions  453   a.    
     Each of the plurality of first portions  453   a  according to another embodiment of the present disclosure may have a flat structure of a circular shape. For example, each of the plurality of first portions  453   a  may have a circular plate shape, but embodiments of the present disclosure are not limited thereto. For example, each of the plurality of first portions  453   a  may have a dot shape including an oval shape, a polygonal shape, or a donut shape. 
     The second portion  453   b  may be disposed between the plurality of first portions  453   a  along each of the first direction X and the second direction Y. The second portion  453   b  may be configured to surround each of the plurality of first portions  453   a , and thus, may be connected to or attached on a side surface of each of the plurality of first portions  453   a . Each of the plurality of first portions  453   a  and the second portion  453   b  may be disposed (or arranged) in parallel on the same plane (or the same layer). 
     In the piezoelectric vibration portion  453  of the vibration device  450  according to another embodiment of the present disclosure, each of the plurality of first portions  453   a  may have a flat structure of a triangular shape instead of a flat structure of a circular shape. For example, each of the plurality of first portions  453   a  may have a triangular plate shape. 
     According to an embodiment of the present disclosure, four adjacent first portions  453   a  among the plurality of first portions  453   a  may be adjacent to one another to form a tetragonal or quadrilateral shape (or a square shape). Vertices of the four adjacent first portions  453   a  forming a tetragonal shape may be adjacent to one another in a center portion (or a central portion) of the tetragonal shape. 
     According to another embodiment of the present disclosure, six adjacent first portions  453   a  among the plurality of first portions  453   a  may be adjacent to one another to form a hexagonal shape (or a regularly hexagonal shape). Vertices of the six adjacent first portions  453   a  forming a hexagonal shape may be adjacent to one another in a center portion (or a central portion) of the hexagonal shape. 
       FIG.  16    illustrates a vibration device according to other embodiment of the present disclosure,  FIG.  17    is a cross-sectional view taken along line II-IF illustrated in  FIG.  16   . 
     With reference to  FIGS.  16  and  17   , a vibration device  450  according to other embodiment of the present disclosure may include at least one or more vibration generator  450 A to  450 D or a plurality of vibration devices  450 A to  450 D.  FIGS.  16  and  17    illustrate an example including four vibration generators, and the vibration device  450  according to the embodiment of the present disclosure may be configured with two or more vibration generator. For example, the vibration generators  450 A to  450 D may be referred to as a vibration module, a vibration generating part, a vibration generating portion, or a vibration generating array, but embodiments of the present disclosure are not limited thereto. 
     The plurality of vibration generators  450 A to  450 D may be electrically separated and disposed while being spaced apart from each other along each of a first direction X and a second direction Y. 
     Each of the plurality of vibration generators  450 A to  450 D may alternately and/or repeatedly contract and expand based on a piezoelectric effect to vibrate. For example, each of the plurality of vibration generators  450 A to  450 D may be arranged or tiled at a certain interval (or distance) along each of the first direction X and the second direction Y. For example, the vibration device  450  in which the plurality of vibration generators  450 A to  450 D are arranged or tiled may be referred to as a sound generator, a vibration array, a vibration array portion, a vibration generating array portion, a vibration array structure, a tiling vibration array, a tiling vibration array module, or a tiling vibration film, but embodiments of the present disclosure are not limited thereto. 
     Each of the plurality of vibration generators  450 A to  450 D according to an embodiment of the present disclosure may have a tetragonal shape. For example, each of the plurality of vibration generators  450 A to  450 D according to an embodiment of the present disclosure may have a tetragonal shape having a width of about 5 cm or more, but embodiments of the present disclosure are not limited thereto. For example, each of the plurality of vibration generators  450 A to  450 D may have a square shape having a size of 5 cm×5 cm or more, but embodiments of the present disclosure are not limited thereto. 
     Each of the plurality of vibration generators  450 A to  450 D may be arranged or tiled at a certain interval (or distance), and thus, may be implemented as one vibration generator (or a single vibration generator) which is driven as one complete single-body without being independently driven. According to an embodiment of the present disclosure, with respect to the first direction X, a first separation distance (or first distance or first interval) D 1  between the plurality of vibration generators  450 A to  450 D may be 0.1 mm or more and smaller than 3 cm, but embodiments of the present disclosure are not limited thereto. Also, with respect to the second direction Y, a second separation distance (or second distance or second interval) D 2  between the plurality of vibration generators  450 A to  450 D may be 0.1 mm or more and smaller than 3 cm, but embodiments of the present disclosure are not limited thereto. For example, the first separation distance D 1  may be the same as the second separation distance D 2  within a process error range. 
     According to an embodiment of the present disclosure, each of the plurality of vibration generators  450 A to  450 D may be arranged or tiled to have the separation distances (or intervals) D 1  and D 2  of 0.1 mm or more and smaller than 3 cm, and thus, may be driven as one vibration generator, thereby increasing a reproduction band and a sound pressure level characteristic of a sound which is generated based on a single-body vibration of the plurality of vibration generators  450 A to  450 D. For example, the plurality of vibration generators  450 A to  450 D may be arranged at an interval of 0.1 mm or more and smaller than 5 mm, in order to increase a reproduction band of a sound generated based on a single-body vibration of the plurality of vibration generators  450 A to  450 D and to increase a sound of a low-pitched sound band (for example, a sound pressure level characteristic in 500 Hz or less). 
     According to an embodiment of the present disclosure, when the plurality of vibration generators  450 A to  450 D are arranged at the intervals D 1  and D 2  of smaller than 0.1 mm or without the intervals D 1  and D 2 , the reliability of the vibration generators  450 A to  450 D or the vibration device  450  may be reduced due to damage or a crack caused by a physical contact therebetween which occurs when each of the vibration generators  450 A to  450 D vibrates. 
     According to an embodiment of the present disclosure, when the plurality of vibration generators  450 A to  450 D are arranged at the intervals D 1  and D 2  of 3 cm or more, the plurality of vibration generators  450 A to  450 D may not be driven as one vibration generator due to an independent vibration of each of the plurality of vibration generators  450 A to  450 D. Therefore, a reproduction band and a sound pressure level characteristic of a sound which is generated based on vibrations of the plurality of vibration generators  450 A to  450 D may be reduced. For example, when the plurality of vibration generators  450 A to  450 D are arranged at the intervals D 1  and D 2  of 3 cm or more, a sound characteristic and a sound pressure level characteristic of the low-pitched sound band (for example, in 500 Hz or less) may each be reduced. 
     According to an embodiment of the present disclosure, when the plurality of vibration generators  450 A to  450 D are arranged at an interval of 5 mm, each of the plurality of vibration generators  450 A to  450 D may not be perfectly driven as one vibration generator, and thus, a sound characteristic and a sound pressure level characteristic of the low-pitched sound band (for example, in 200 Hz or less) may each be reduced. 
     According to another embodiment of the present disclosure, when the plurality of vibration generators  450 A to  450 D are arranged at an interval of 1 mm, each of the plurality of vibration generators  450 A to  450 D may be driven as one vibration generator, and thus, a reproduction band of a sound may increase and a sound of the low-pitched sound band (for example, a sound pressure level characteristic in 500 Hz or less) may increase. For example, when the plurality of vibration generators  450 A to  450 D are arranged at an interval of 1 mm, the vibration device  450  may be implemented as a large-area vibrator which is enlarged based on optimization of a separation distance between the plurality of vibration generators  450 A to  450 D. Therefore, the vibration device  450  may be driven as a large-area vibrator based on a single-body vibration of the plurality of vibration generators  450 A to  450 D, and thus, a sound characteristic and a sound pressure level characteristic may each increase or enhance in the low-pitched sound band and a reproduction band of a sound generated based on a large-area vibration of the vibration device  450 . 
     Therefore, to implement a single-body vibration (or one vibration generator) of the plurality of vibration generators  450 A to  450 D, a separation distance between the plurality of vibration generators  450 A to  450 D may be adjusted to 0.1 mm or more and smaller than 3 cm. Also, to implement a single-body vibration (or one vibration generator) of the plurality of vibration generators  450 A to  450 D and to increase a sound pressure level characteristic of a sound of the low-pitched sound band, the separation distance between the plurality of vibration generators  450 A to  450 D may be adjusted to 0.1 mm or more and smaller than 5 mm. 
     The vibration device  450  according to an embodiment of the present disclosure may include first to fourth vibration generators  450 A to  450 D which are electrically disconnected (or separated) and/or structurally separated from one another and are disposed spaced apart from one another along each of the first direction X and the second direction Y. For example, the first to fourth vibration generators  450 A to  450 D may be arranged or tiled in 2×2 form. 
     According to an embodiment of the present disclosure, the first and second vibration generators  450 A and  450 B may be spaced apart from each other along the first direction X. The third and fourth vibration generators  450 C and  450 D may be spaced apart from each other in the first direction X and may be spaced apart from each of the first and second vibration generators  450 A and  450 B along the second direction Y. The first and third vibration generators  450 A and  450 C may be spaced apart from each other along the second direction Y to face each other. The second and fourth vibration generators  450 B and  450 D may be spaced apart from each other along the second direction Y to face each other. 
     Each of the first to fourth vibration generators  450 A to  450 D according to an embodiment of the present disclosure may include a piezoelectric vibration portion  453 , a first electrode portion E 1 , and a second electrode portion E 2 . 
     The piezoelectric vibration portion  453  may include a ceramic-based material capable of realizing a relatively high vibration. For example, the piezoelectric vibration portion  453  may include a 1-3 composite structure having a piezoelectric characteristic of a 1-3 vibration mode or a 2-2 composite structure having a piezoelectric characteristic of a 2-2 vibration mode. For example, the piezoelectric vibration portion  453  may include the first portions  453   a  and the second portion  453   b  similar to the piezoelectric vibration portion  453  described above with reference to  FIGS.  13  to  15   , and thus, like reference numerals refer to like elements and their repetitive descriptions may be omitted. 
     The first electrode portion E 1  may be disposed at a first surface of the piezoelectric vibration portion  453  and may be electrically connected to the first surface of the piezoelectric vibration portion  453 . For example, the first electrode portion E 1  may be substantially the same as the first electrode portion E 1  described above with reference to  FIGS.  13  to  15   , and thus, like reference numerals refer to like elements and their repetitive descriptions may be omitted. 
     The second electrode portion E 2  may be disposed at a second surface of the piezoelectric vibration portion  453 , and may be electrically connected to the second surface of the piezoelectric vibration portion  453 . For example, the second electrode portion E 2  may be substantially the same as the second electrode portion E 2  described above with reference to  FIGS.  13  to  15   , and thus, like reference numerals refer to like elements and their repetitive descriptions may be omitted. 
     The piezoelectric vibration portion  453  according to an embodiment of the present disclosure, as described above with reference to  FIG.  12   , may be formed of a transparent, semitransparent, or opaque piezoelectric and may be transparent, semitransparent, or opaque. 
     The vibration device  450  according to another embodiment of the present disclosure may further include a first protection member  456  and a second protection member  457 . 
     The first protection member  456  may be disposed on the first surface of the vibration device  450 . For example, the first protection member  456  may cover the first electrode portion E 1  disposed on a first surface of each of the plurality of vibration generators  450 A to  450 D. Thus, the first protection member  456  may be connected to the first surface of each of the plurality of vibration generators  450 A to  450 D in common or may support the first surface of each of the plurality of vibration generators  450 A to  450 D in common. Accordingly, the first protection member  456  may protect the first surface of each of the plurality of vibration generators  450 A to  450 D or the first electrode portion E 1 . 
     According to an embodiment of the present disclosure, a first adhesive layer  454  may be disposed between the first protection member  456  and each of the plurality of vibration generators  450 A to  450 D. For example, the first protection member  456  may be disposed at the first surface of each of the plurality of vibration generators  450 A to  450 D by the first adhesive layer  454 . For example, the first protection member  456  may be directly disposed at the first surface of each of the plurality of vibration generators  450 A to  450 D by a film laminating process using the first adhesive layer  454 . Accordingly, the plurality of vibration generators  450 A to  450 D may be integrated (or disposed) or tiled with the first protection member  456  to have the certain intervals D 1  and D 2 . 
     The second protection member  457  may be disposed on the second surface of the vibration device  450 . For example, the second protection member  457  may cover the second electrode portion E 2  disposed on a second surface of each of the plurality of vibration generators  450 A to  450 D. Thus, the second protection member  457  may be connected to the second surface of each of the plurality of vibration generators  450 A to  450 D in common or may support the second surface of each of the plurality of vibration generators  450 A to  450 D in common. Accordingly, the second protection member  457  may protect the second surface of each of the plurality of vibration generators  450 A to  450 D or the second electrode portion E 2 . 
     According to an embodiment of the present disclosure, a second adhesive layer  455  may be disposed between the second protection member  457  and each of the plurality of vibration generators  450 A to  450 D. For example, the second protection member  457  may be disposed at the second surface of each of the plurality of vibration generators  450 A to  450 D by the second adhesive layer  455 . For example, the second protection member  457  may be directly disposed at the second surface of each of the plurality of vibration generators  450 A to  450 D by a film laminating process by the second adhesive layer  455 . Accordingly, the plurality of vibration generators  450 A to  450 D may be integrated (or disposed) or tiled with the second protection member  457  to have the certain intervals D 1  and D 2 . 
     Each of the first protection member  456  and the second protection member  457  according to an embodiment of the present disclosure may include a plastic material, a fiber material, or a wood material. Any one of the first protection member  456  and the second protection member  457  may be attached or coupled to the display device by an adhesive member. 
     The first adhesive layer  454  may be disposed at the first surface of each of the plurality of vibration generators  450 A to  450 D, and between the plurality of vibration generators  450 A to  450 D. For example, the first adhesive layer  454  may be formed at a rear surface (or an inner surface) of the first protection member  456  facing the first surface of the vibration device  450 , disposed at the first surface of each of the plurality of vibration generators  450 A to  450 D, and filled between the plurality of vibration generators  450 A to  450 D. 
     The second adhesive layer  455  may be disposed at the second surface of each of the plurality of vibration generators  450 A to  450 D, and between the plurality of vibration generators  450 A to  450 D. For example, the second adhesive layer  455  may be formed at a front surface (or an inner surface) of the second protection member  457  facing the second surface of the vibration device  450 , disposed at the second surface of each of the plurality of vibration generators  450 A to  450 D, and filled between the plurality of vibration generators  450 A to  450 D. 
     The first and second adhesive layers  454  and  455  may be connected or coupled to each other between the plurality of vibration generators  450 A to  450 D. Therefore, each of the plurality of vibration generators  450 A to  450 D may be surrounded by the first and second adhesive layers  454  and  455 . For example, the first and second adhesive layers  454  and  455  may entirely surround the whole plurality of vibration generators  450 A to  450 D. For example, the plurality of vibration generators  450 A to  450 D may be embedded between the first and second adhesive layers  454  and  455 . For example, the first and second adhesive layers  454  and  455  may be referred to as a cover member, but embodiments of the present disclosure are not limited thereto. When the first and second adhesive layers  454  and  455  are a cover member, the first protection member  456  may be disposed at a first surface of the cover member, and the second protection member  457  may be disposed at a second surface of the cover member. 
     Each of the first and second adhesive layers  454  and  455  according to an embodiment of the present disclosure may include an electric insulating material which has adhesiveness and is capable of compression and decompression. For example, each of the first and second adhesive layers  454  and  455  may include an epoxy resin, an acryl resin, a silicone resin, or a urethane resin, but embodiments of the present disclosure are not limited thereto. For example, each of the first and second adhesive layers  454  and  455  may be configured to be transparent, semitransparent, or opaque according to the location of the vehicle where the vibration device  450  is disposed. 
     The vibration device  450  according to another embodiment of the present disclosure may further include a first power supply line PL 1  disposed at the first protection member  456 , a second power supply line PL 2  disposed at the second protection member  457 , and a pad part  458  electrically connected to the first power supply line PL 1  and the second power supply line PL 2 . 
     The first power supply line PL 1  may be disposed at a rear surface of the first protection member  456  facing the first surface of the vibration device  450 . The first power supply line PL 1  may be electrically connected to the first electrode portion E 1  of each of the plurality of vibration generators  450 A to  450 D.

     With reference to  FIG.  18   , in a case where partitions having different sizes are applied, it may be seen that a sound pressure level is enhanced in a total frequency range. For example, in the dotted line, it may be seen that a sound pressure level in 180 Hz or more increases more than the solid line. For example, in the dotted line, it may be seen that a sound pressure level in 180 Hz or more increases by about 10 dB more than the solid line. Partitions near a vibration device may be configured to have different sizes, and thus, a sound band of a total frequency may be output by compensating for a sound band. Accordingly, according to an embodiment of the present disclosure, partitions near a vibration device may be configured to have different sizes, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or more and/or a sound band of a full range.
