It is to be understood that both the foregoing description and the following description of the present disclosure are exemplary and explanatory and are intended to provide further explanation of the disclosure as claimed.

Throughout the drawings and the detailed description, unless otherwise described, the same drawing reference numerals should be understood to refer to the same elements, features, and structures. The sizes, lengths, and thicknesses of layers, regions and elements, and depiction of thereof can be exaggerated for clarity, illustration, and/or convenience.

DETAILED DESCRIPTION OF THE DISCLOSURE

Reference is now made in detail to aspects of the present disclosure, examples of which can be illustrated in the accompanying drawings. In the following description, when a detailed description of well-known methods, functions, structures or configurations can unnecessarily obscure aspects of the present disclosure, a detailed description of such known functions or configurations can have been omitted for brevity. Further, repetitive descriptions can be omitted for brevity. The progression of processing steps and/or operations described is a non-limiting example.

The sequence of steps and/or operations is not limited to that set forth herein and can be changed to occur in an order that is different from an order described herein, with the exception of steps and/or operations necessarily occurring in a particular order. In one or more examples, two operations in succession can be performed substantially concurrently, or the two operations can be performed in a reverse order or in a different order depending on a function or operation involved.

Unless stated otherwise, like reference numerals can refer to like elements throughout even when they are shown in different drawings. Unless stated otherwise, the same reference numerals may be used to refer to the same or substantially the same elements throughout the specification and the drawings. In one or more aspects, identical elements (or elements with identical names) in different drawings can have the same or substantially the same functions and properties unless stated otherwise. Names of the respective elements used in the following explanations are selected only for convenience and can be thus different from those used in actual products.

Advantages and features of the present disclosure, and implementation methods thereof, are clarified through the aspects 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 example aspects set forth herein. Rather, these example aspects are examples and are provided so that this disclosure can be thorough and complete to assist those skilled in the art to understand the inventive concepts without limiting the protected scope of the present disclosure.

Shapes, dimensions (e.g., sizes, lengths, widths, heights, thicknesses, locations, radii, diameters, and areas), proportions, ratios, angles, numbers, the number of elements, and the like disclosed herein, including those illustrated in the drawings, are merely examples, and thus, the present disclosure is not limited to the illustrated details. It is, however, noted that the relative dimensions of the components illustrated in the drawings are part of the present disclosure.

Where a term like “comprise,” “have,” “include,” “contain,” “constitute,” “made of,” “formed of,” “composed of,” or the like is used with respect to one or more elements (e.g., layers, films, regions, components, sections, members, parts, regions, areas, portions, steps, operations, and/or the like), one or more other elements can be added unless a term such as “only” or the like is used. The terms used in the present disclosure are merely used in order to describe example aspects, and are not intended to limit the scope of the present disclosure. The terms of a singular form can include plural forms unless the context clearly indicates otherwise.

The word “exemplary” is used to mean serving as an example or illustration, unless otherwise specified. Embodiments are example embodiments. Aspects are example aspects. Here, in one or more implementations, “embodiments,” “aspects,” “examples,” and the like should not be construed to be preferred or advantageous over other implementations. An aspect, an example, an example aspect, or the like can refer to one or more aspects, one or more examples, one or more example aspects, or the like, unless stated otherwise. Further, the term “can” encompasses all the meanings of the term “may.”

In one or more aspects, unless explicitly stated otherwise, an element, feature, or corresponding information (e.g., a level, range, dimension, size, or the like) is construed to include an error or tolerance range even where no explicit description of such an error or tolerance range is provided. An error or tolerance range can be caused by various factors (e.g., process factors, internal or external impact, noise, or the like). In interpreting a numerical value, the value is interpreted as including an error range unless explicitly stated otherwise.

In describing a positional relationship, when the positional relationship between two parts (e.g., layers, films, regions, components, sections, or the like) is described, for example, using “on,” “upon,” “on top of,” “over,” “under,” “above,” “below,” “beneath,” “near,” “close to,” “adjacent to,” “beside,” “next to,” “at or on a side of,” or the like, one or more other parts can be located between the two parts unless a more limiting term, such as “immediate (ly),” “direct (ly),” or “close (ly),” is used. For example, where a structure is described as being positioned “on,” “upon,” “on top of,” “over,” “under,” “above,” “below,” “beneath,” “near,” “close to,” “adjacent to,” “beside,” “next to,” “at or on a side of,” or the like 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 one or more additional structures are disposed or interposed therebetween. Furthermore, the terms “front,” “rear,” “back,” “left,” “right,” “top,” “bottom,” “downward,” “upward,” “upper,” “lower,” “up,” “down,” “column,” “row,” “vertical,” “horizontal,” and the like refer to an arbitrary frame of reference.

Spatially relative terms, such as “below,” “beneath,” “lower,” “on,” “above,” “upper” and the like, can be used to describe a correlation between various elements (e.g., layers, films, regions, components, sections, or the like) as shown in the drawings. The spatially relative terms are to be understood as terms including different orientations of the elements in use or in operation in addition to the orientation depicted in the drawings. For example, if the elements shown in the drawings are turned over, elements described as “below” or “beneath” other elements would be oriented “above” other elements. Thus, the term “below,” which is an example term, can include all directions of “above” and “below.” Likewise, an exemplary term “above” or “on” can include both directions of “above” and “below.”

In describing a temporal relationship, when the temporal order is described as, for example, “after,” “subsequent,” “next,” “before,” “preceding,” “prior to,” or the like, a case that is not consecutive or not sequential can be included and thus one or more other events can occur therebetween, unless a more limiting term, such as “just,” “immediate (ly),” or “direct (ly),” is used.

The terms, such as “below,” “lower,” “above,” “upper” and the like, can be used herein to describe a relationship between element(s) as illustrated in the drawings. It will be understood that the terms are spatially relative and based on the orientation depicted in the drawings.

It is understood that, although the terms “first,” “second,” or the like can be used herein to describe various elements (e.g., layers, films, regions, components, sections, members, parts, regions, areas, portions, steps, operations, and/or the like), these elements should not be limited by these terms, for example, to any particular order, sequence, precedence, or number of elements. These terms are used only to distinguish one element from another. For example, a first element can denote a second element, and, similarly, a second element can denote a first element, without departing from the scope of the present disclosure. Furthermore, the first element, the second element, and the like can be arbitrarily named according to the convenience of those skilled in the art without departing from the scope of the present disclosure. For clarity, the functions or structures of these elements (e.g., the first element, the second element and the like) are not limited by ordinal numbers or the names in front of the elements. Further, a first element can include one or more first elements. Similarly, a second element or the like can include one or more second elements or the like.

In describing elements of the present disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” or the like can be used. These terms are intended to identify the corresponding element(s) from the other element(s), and these are not used to define the essence, basis, sequence, order, or number of the elements.

For the expression that an element (e.g., layer, film, region, component, section, or the like) is described as “connected,” “coupled,” “attached,” “adhered,” or the like to another element, the element can not only be directly connected, coupled, attached, adhered, or the like to another element, but also be indirectly connected, coupled, attached, adhered, or the like to another element with one or more intervening elements disposed or interposed between the elements, unless otherwise specified.

For the expression that an element (e.g., layer, film, region, component, section, or the like) “contacts,” “overlaps,” or the like with another element, the element can not only directly contact, overlap, or the like with another element, but also indirectly contact, overlap, or the like with another element with one or more intervening elements disposed or interposed between the elements, unless otherwise specified.

The phrase that an element (e.g., layer, film, region, component, section, or the like) is “provided,” “disposed,” “connected,” “coupled,” or the like in, on, with or to another element can be understood, for example, as that at least a portion of the element is provided in, disposed, connected, coupled, or the like in, on, with or to at least a portion of another element, or that the entirety of the element is provided, disposed, connected, coupled or the like in, on, with or to another element. The phrase that an element (e.g., layer, film, region, component, section, or the like) “contacts,” “overlaps,” or the like with another element can be understood, for example, as that at least a portion of the element contacts, overlaps, or the like with a least a portion of another element, that the entirety of the element contacts, overlaps, or the like with a least a portion of another element, or that at least a portion of the element contacts, overlaps, or the like with the entirety of another element.

The terms such as a “line” or “direction” should not be interpreted only based on a geometrical relationship in which the respective lines or directions are parallel or perpendicular to each other. Such terms can mean a wider range of lines or directions within which the components of the present disclosure can operate functionally. For example, the terms “first direction,” “direction,” and the like, such as a direction parallel or perpendicular to “x-axis,” “y-axis,” or “z-axis,” should not be interpreted only based on a geometrical relationship in which the respective directions are parallel or perpendicular to each other, and can be meant as directions having wider directivities within the range within which the components of the present disclosure can operate functionally.

The term “at least one” should be understood as including any and all combinations of one or more of the associated listed items. For example, each of the phrases “at least one of a first item, a second item, or a third item” and “at least one of a first item, a second item, and a third item”, can represent (i) a combination of items provided by one or more of the first item, the second item, and the third item or (ii) only one of the first item, the second item, and the third item.

The expression of a first element, a second elements, “and/or” a third element should be understood to encompass one of the first, second, and third elements, as well as any and all combinations of the first, second and third elements. By way of example, A, B and/or C encompass only A; only B; only C; any of A, B, and C (e.g., A, B, or C); some combinations of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. Furthermore, an expression “A/B” can be understood as A and/or B. For example, an expression “A/B” can refer to only A; only B; A or B; or A and B.

In one or more aspects, the terms “between” and “among” can be used interchangeably simply for convenience unless stated otherwise. For example, an expression “between a plurality of elements” can be understood as among a plurality of elements. In another example, an expression “among a plurality of elements” can be understood as between a plurality of elements. In one or more examples, the number of elements can be two. In one or more examples, the number of elements can be more than two. Furthermore, when an element (e.g., layer, film, region, component, sections, or the like) is referred to as being “between” at least two elements, the element can be the only element between the at least two elements, or one or more intervening elements can also be present.

In one or more aspects, the phrases “each other” and “one another” can be used interchangeably simply for convenience unless stated otherwise. For example, an expression “different from each other” can be understood as different from one another. In another example, an expression “different from one another” can be understood as different from each other. In one or more examples, the number of elements involved in the foregoing expression can be two. In one or more examples, the number of elements involved in the foregoing expression can be more than two.

In one or more aspects, the phrases “one or more among” and “one or more of” can be used interchangeably simply for convenience unless stated otherwise.

The term “or” means “inclusive or” rather than “exclusive or.” For example, unless otherwise stated or clear from the context, the expression that “x uses a or b” means any one of natural inclusive permutations. For example, “a or b” can mean “a,” “b,” or “a and b.” For example, “a, b or c” can mean “a,” “b,” “c,” “a and b,” “b and c,” “a and c,” or “a, b and c.”

Features of various aspects of the present disclosure can be partially or entirely coupled to or combined with each other, can be technically associated with each other, and can be operated, linked, or driven together in various ways. Aspects of the present disclosure can be implemented or carried out independently from each other, or can be implemented or carried out together in a co-dependent or related relationship. In one or more aspects, the components of each apparatus according to various aspects of the present disclosure can be operatively coupled and configured.

Unless otherwise defined, the terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example aspects belong. It should be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is, for example, consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense, unless expressly defined otherwise herein.

The terms used herein have been selected as being general in the related technical field; however, there can be other terms depending on the development and/or change of technology, convention, preference of technicians, and so on. Therefore, the terms used herein should not be understood as limiting technical ideas, but should be understood as examples of the terms for describing example aspects.

Further, in a specific case, a term can be arbitrarily selected by an applicant, and in this case, the detailed meaning thereof is described herein. Therefore, the terms used herein should be understood based on not only the name of the terms, but also the meaning of the terms and the content hereof.

Furthermore, “X-axis direction,” “Y-axis direction,” and “Z-axis direction,” should not be construed by a geometric relation only of a mutual vertical relation and can have broader directionality within the range that elements of the present disclosure can act functionally.

In the following description, various example aspects of the present disclosure are described in detail with reference to the accompanying drawings. With respect to reference numerals to elements of each of the drawings, the same elements can be illustrated in other drawings, and like reference numerals can refer to like elements unless stated otherwise. The same or similar elements can be denoted by the same reference numerals even though they are depicted in different drawings.

In addition, for convenience of description, a scale, dimension, size, and thickness of each of the elements illustrated in the accompanying drawings can be different from an actual scale, dimension, size, and thickness, and thus, aspects of the present disclosure are not limited to a scale, dimension, size, and thickness illustrated in the drawings.

For example, the connection member380can include a material having an adhesive force which differs from that of at least one of the first coupling member321and the second coupling member322. Because the connection member380includes a material having an adhesive force which differs from that of at least one of the first coupling member321and the second coupling member322, a separation or detachment process (or rework) of the connection member380from the vehicle interior material130can be easily performed in a separation or detachment process (or rework) of the sound apparatus30attached on the vehicle interior material130. Accordingly, a process of attaching or mounting the sound apparatus30on the vehicle interior material130or a process of separating or attaching/detaching the sound apparatus30from the vehicle interior material130can be easily performed.

The connection member380can be coupled (or attached) to the rear surface of the enclosure310and can contact (or surface-contact) a first surface130s1of the vehicle interior material130, but embodiments of the present disclosure are not limited thereto. For example, in a case where the connection member380is coupled (or attached) to the rear surface of the enclosure310and simply contacts (or surface-contacts) the first surface130s1of the vehicle interior material130, a process of separating or detaching (or rework) the connection member380from the vehicle interior material130without damage of the sound apparatus30or the vehicle interior material130can be easily performed in a process of separating and detaching (or rework) the sound apparatus30from the vehicle interior material130.

The hole380ocan be disposed to correspond to (or overlap) the opening part310o. The hole380ocan have a same shape as the opening part310o, but embodiments of the present disclosure are not limited thereto. For example, the hole380ocan have a same shape as that of the opening part310oand can have a size which is greater than that of the opening part310o. Accordingly, a sound based on a vibration of the sound generating module330can be output to an interior space IS of a vehicle by (or through) the opening part310oand the hole380o. For example, the hole380ocan be an opening part, an opening hole, a slit, a slot, a connection hole, or an intermediate hole, but embodiments of the present disclosure are not limited thereto.

According to an embodiment of the present disclosure, the hole380ocan correspond to (or overlap) the hole135of the vehicle interior material130. The hole380ocan be between the hole135of the vehicle interior material130and the opening part310oof the enclosure310. For example, the hole380ocan be between the hole135of the vehicle interior material130and the opening part310oof the first enclosure311.

With reference toFIGS.25A and25B, a thickness T1of the connection member380can differ from that of at least one of the first coupling member321and the second coupling member322. For example, the thickness T1of the connection member380can be thicker than that of at least one of the first coupling member321and the second coupling member322. The thickness T1of the connection member380can be 0.5 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the thickness T1of the connection member380can be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto. For example, the connection member380can have the thickness T1which is obtained by compressing an initial thickness T1′ with a coupling force between the coupling part500and the first enclosure311. Accordingly, the connection member380can surface-contact with the vehicle interior material130including at least one or more curved portions136, based on a coupling force between the coupling part500and the first enclosure311.

According to another embodiment of the present disclosure, the connection member380can have a compressive force (or a contractive force) and an elastic restoring force and can be contracted or compressed by coupling between the coupling part500and the first enclosure311.

For example, the length (or the thickness) of the connection member380can be smaller than or equal to a length (or a thickness) of the first enclosure311.

The connection member380, as illustrated inFIG.25B, can have the initial thickness T1′ before compression (or contraction) and can be compressed (or contracted) to have a deformed thickness (or a compression thickness) T1illustrated inFIG.25A, based on pressure applied from the enclosure310by coupling (or connection) between the coupling part500and the enclosure310. For example, when the sound apparatus30is connected to the vehicle interior material130by the coupling part500or assembly and/or rework are/is completed, a thickness of the connection member380can be compressed from the initial thickness T1′ to the compression thickness T1, and thus, a vibration of the enclosure310can be efficiently transferred to the vehicle interior material130. For example, when the sound apparatus30is separated (or detached) from the vehicle interior material130by the detachment of the coupling part500, the connection member380can be restored from the deformed thickness (or the compression thickness) T1to the initial thickness T1′ by an elastic restoring force.

With reference toFIGS.25A and25B, the coupling part500can be connected or coupled to the sound apparatus30through the second hole135of the vehicle interior material130, the hole380oof the connection member380, and the opening part310oof the first enclosure311(an arrow direction).

For example, the coupling part500can be accommodated or inserted into the hole380oof the connection member380and the opening part310oof the first enclosure311through the hole135of the vehicle interior material130, in the interior space of the vehicle. For example, the hook member504of the coupling part500can be connected or coupled to the opening part310oof the first enclosure311. For example, the hook member504of the coupling part500can be inserted (or accommodated) into the opening part310oof the first enclosure311and can be connected or coupled to a slope surface311sof the first enclosure311by a hook coupling scheme.

For example, the at least one or more holes331ocan perform control so that air flows in the internal spaces313of the enclosure310spatially separated from each other by the vibration member331. For example, the at least one or more holes331ocan be configured to adjust air flow between a first space313aand a second space313bspatially separated from each other by the vibration member331in the internal space313of the enclosure310. For example, the at least one or more holes331ocan be a first hole, a vent hole, an air flow hole, a ventilation hole, a duct hole, a first connection hole, a first communication hole, or a first space connection part, but embodiments of the present disclosure are not limited thereto.

For example, the at least one or more holes331ocan be configured to decrease an air pressure of the first space313aof the first enclosure311or the first space313aprovided between the vibration member331and the first enclosure311. Accordingly, a band (reproduction band) of a low-pitched sound band can expand, and thus, a sound characteristic and/or a sound pressure level characteristic of the low-pitched sound band can be improved. Further, the sound generating module330can be more stably vibrated by the at least one or more holes331oin the vibration member331, and thus, a sound characteristic and/or a sound pressure level characteristic can be further improved.

For example, the at least one or more holes331ocan be disposed adjacent to a lateral surface of each of the vibration apparatuses333and335. For example, a distance between the at least one or more holes331oand each of the vibration apparatuses333and335can be smaller than a distance between the at least one or more holes331oand a sidewall (or lateral surface) of the enclosure310. For example, when the at least one or more holes331ois disposed at a position farther away from each of the vibration apparatuses333and335, a sound characteristic and/or a sound pressure level characteristic of a low-pitched sound band can be further improved.

According to an embodiment of the present disclosure, the at least one or more holes331ocan be configured at the vibration member331adjacent to the vibration apparatuses333and335with the vibration apparatuses333and335therebetween.
