Title: Loudspeaker apparatus, loudspeaker, and structure

Description:
TECHNICAL FIELD 
     The present technology relates to a loudspeaker apparatus, a loudspeaker, and a structure. 
     BACKGROUND ART 
     In an electronic apparatus described in Patent Literature 1, loudspeakers are disposed on both left and right sides below a liquid-crystal display unit. Sounds output from the loudspeakers are output to the front side via slits that function as passing holes (paragraphs [0015] to [0025] in the specification,  FIGS. 1 to 3 , and the like of Patent Literature 1). 
     In a television (television set) described in Patent Literature 2, loudspeakers are disposed on left and right side surfaces of a cathode-ray tube. A reflector that reflects sounds from the loudspeakers to the front side of the television screen is disposed in front of the loudspeaker. Moreover, an acoustic lens capable of controlling the directivity of sounds reflected by the reflector is disposed at a position on approximately the same plane as the television image. Accordingly, sound images can be made clear and high-quality sounds matching pictures can be output without increasing the size of the television cabinet (paragraphs [0009] to [0021] in the specification,  FIGS. 1  and  2 , and the like of Patent Literature 2).

     MODE(S) FOR CARRYING OUT THE INVENTION 
     Hereinafter, embodiments according to the present technology will be described with reference to the drawings. 
     [Configuration of Electronic Apparatus] 
       FIG. 1  is a diagram schematically showing an outer appearance example of a television (television set) according to an embodiment of the present technology. 
     Hereinafter, descriptions will be given assuming that as a television  1  is viewed from the front side, a left-and-right direction is defined as an X direction, a depth direction is defined as a Y direction, and a height direction is defined as a Z direction. 
     Moreover, as for each portion or unit, the wordings “right side”, “left side”, “deep side”, “front side”, “upper side”, and “lower side”, which are based on each of the XYZ directions, will be used in some cases. Moreover, the wordings “front side” and “back side” will be used in some cases in the depth direction (the Y direction). 
     The television  1  generally has a plate-like shape and is configured as a so-called flat-panel display television. The television  1  includes a display  2 , a casing portion  3 , loudspeaker boxes  4 , and a stand  5 . 
     The display  2  is disposed in the substantially entire area of a front surface of the television  1  and displays content such as a television program. In addition, as the display  2  is connected to an external content reproduction apparatus or the like, the display  2  can also display content output from the content reproduction apparatus or the like. 
     In this embodiment, a liquid-crystal display is used as the display  2 . The present technology is not limited thereto, and an arbitrary display device such as a display using electro-luminescence (EL) or the like may be employed as the display  2 . 
     The casing portion  3  holds the display  2  on the front side of the television  1 . The casing portion  3  has an upper holding portion  3   a , a lower holding portion  3   b , a left holding portion  3   c , and a right holding portion  3   d , which are disposed in the upper and lower, left and right portions of the display  2 . Moreover, the casing portion  3  has a rear cover  3   e  (see  FIG. 3 ) that is disposed on the back side of the display  2 . 
     The casing portion  3  is constituted by the upper holding portion  3   a , the lower holding portion  3   b , the left holding portion  3   c , the right holding portion  3   d , and the rear cover  3   e . An internal space S 1  (see  FIG. 3 ) is formed inside the casing portion  3 . A display unit  13  (see  FIG. 3 ) including the display  2 , various control boards (see  FIG. 2 ), the loudspeaker boxes  4 , and the like are disposed in this internal space S 1 . 
     The upper holding portion  3   a , the lower holding portion  3   b , the left holding portion  3   c , and the right holding portion  3   d  that hold the periphery of the display  2  are also called bezel. 
     The casing portion  3  is constituted by a metal material such as aluminum, for example. 
     The loudspeaker boxes  4  are disposed in the internal space S 1  of the television  1 . In this embodiment, four loudspeaker boxes  4   a  to  4   d  are disposed as shown in  FIG. 1 . 
     As the television  1  is viewed from the front side, the loudspeaker box  4   a  is disposed at the upper left position and the loudspeaker box  4   b  is disposed at the upper right position. Also, the loudspeaker box  4   c  is disposed at the lower left position and the loudspeaker box  4   b  is disposed at the lower right position. 
     The loudspeaker box  4   a  and the loudspeaker box  4   b  are disposed at positions to be left-right symmetric to each other with respect to a center line (not shown) extending from the center position of the display  2  in the upper-and-lower direction. The loudspeaker box  4   c  and the loudspeaker box  4   d  are also disposed at positions to be left-right symmetric to each other with respect to the same center line. 
     Moreover, the loudspeaker box  4   a  and the loudspeaker box  4   c  are disposed at the same position in the left-and-right direction (the X direction). Moreover, the loudspeaker box  4   b  and the loudspeaker box  4   d  are also disposed at the same position in the left-and-right direction. Therefore, the four loudspeaker boxes  4   a  to  4   d  are disposed at positions to be symmetric to each other with respect to the center position of the display  2 . 
     The number, arrangement, and the like of the loudspeaker boxes  4  are not limited, and may be arbitrarily set. For example, as the television  1  is viewed from the front side, an arbitrary number of loudspeaker boxes  4  may be disposed only on the upper side. In contrast, an arbitrary number of loudspeaker boxes  4  may be disposed only on the lower side. Alternatively, an arbitrary number of loudspeaker boxes  4  may be disposed on the left side or the right side. As a matter of course, the loudspeaker boxes  4   a  to  4   d  shown in  FIG. 1  may be disposed to be deviated from each other in the left-and-right direction or the upper-and-lower direction. 
     In this embodiment, an example in which the four loudspeaker boxes  4  having the same configuration are used will be shown. 
     The loudspeaker boxes  4  include a plurality of loudspeakers (see  FIG. 6 ). The loudspeaker boxes  4  are disposed in the internal space S 1  of the television  1  such that the loudspeakers  7  are made to face the front side of the television  1 . That is, a sound output side of the loudspeakers  7  of the loudspeaker boxes  4  is made to face the front side of the television  1 . 
     In the present disclosure, “being made to face the front side” is not limited to a case where a sound output direction of the loudspeakers  7  is completely identical to the front direction (the Y direction) pf the television  1 . It also includes a state in which the output side of the loudspeakers  7  is made to face substantially the front side of the television  1 . For example, the concept of “being made to face the front side” also includes a case where the angle of intersection of the sound output direction of the loudspeakers with the front direction (the Y direction) of the television  1  is within a predetermined margin of error. 
     The predetermined margin of error can be defined to be a range of 10 degrees or less, for example. 
     The stand  5  is connected to the lower holding portion  3   b  of the casing portion  3  and supports the display  2  and the casing portion  3 . The specific configuration of the stand  5  is not limited, and may be arbitrarily designed. Moreover, a configuration without the stand  5  is also possible. 
     For example, the television  1  may be installed on a wall or the like. 
       FIG. 2  is a schematic diagram showing the back side of the television  1  and is a diagram of a state in which the rear cover  3   e  is removed. As described above, the four loudspeaker boxes  4  are disposed in the internal space S 1 . Moreover, the loudspeaker boxes  4  include the plurality of loudspeakers  7 . 
     The loudspeakers  7  are dynamic speaker units and have a diaphragm, a frame, a voice coil, and the like. 
     In this embodiment, one loudspeaker (hereinafter, referred to as a tweeter)  7   a  for high sounds and two loudspeakers  7   b  for middle sounds are installed in the loudspeaker box  4 . 
     The tweeter  7   a  and the loudspeakers  7   b  for middle sounds are disposed such that their sound output directions are the same. The sound output side of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds is made to face the front side of the television  1 . 
     Moreover, various control boards  8  are disposed inside the internal space S 1  of the television  1  so as to face the back side. 
     Moreover, loudspeakers  9  for low sounds are disposed in the internal space S 1 . The loudspeakers  9  for low sounds are dynamic speaker units and have a diaphragm, a frame, a voice coil, and the like. 
     The loudspeakers  9  for low sounds are disposed such that their output side faces the back side of the television  1 . 
     Sound passing holes are formed at positions in the rear cover  3   e  that correspond to the positions of the loudspeakers  9  for low sounds. 
     Sounds output from the loudspeakers  9  for low sounds are emitted into the external space through the sound passing holes of the rear cover  3   e . Then, the sounds pass above or below the casing portion  3  and reach the front side of the television  1 . 
     As the television  1  is viewed from the front side, the loudspeaker boxes  4   a  and  4   c  disposed on the left side output left-channel sounds. The loudspeaker boxes  4   a  and  4   c  disposed on the right side output right-channel sounds. Accordingly, sound output on a stereo mode is realized. 
     The loudspeakers  7  installed in the loudspeaker boxes  4  face the front side. Moreover, the four loudspeaker boxes  4  are disposed at positions symmetric to each other with respect to the center position of the display  2 . Accordingly, a sound image is localized at the center portion of the display  2  and a favorable viewing environment in which images or pictures match sounds can be provided. 
     The loudspeaker boxes  4  may perform sound output on a mono mode. 
     The loudspeakers  9  for low sounds perform the sound output on the mono mode. As a matter of course, the loudspeakers  9  for low sounds can also perform the sound output on the stereo mode. 
     The specific configurations of the tweeter  7   a , the loudspeakers  7   b  for middle sounds, and the loudspeakers  9  for low sounds are not limited, and may be arbitrarily designed. 
     [Loudspeaker Box] 
     Examples of the configuration of the loudspeaker box  4   a  and the installation of the loudspeaker box  4   a  into the television  1  will be described. 
       FIG. 3  is an enlarged diagram of the portion of the upper left loudspeaker box  4   a  shown in  FIG. 1 . 
       FIG. 4  is a diagram of the enlarged portion shown in  FIG. 3  as viewed from on the front side of the television  1 . 
       FIG. 5  is a cross-sectional view schematically showing a cross-section taken along the line A-A of  FIG. 4 . 
       FIG. 6  is a perspective view schematically showing an outer appearance example of the loudspeaker box  4 . 
     As shown in  FIGS. 3 and 5 , the upper holding portion  3   a  has a stepped structure in which a first frame  11  constituting a first step portion and a second frame  12  constituting a second step portion are integrally configured. 
     The first frame  11  has a cross-section having a shape like a U-shape inverted upside down and includes a front surface portion  11   a , an upper surface portion  11   b , and a front surface portion  11   c.    
     The second frame  12  has a cross-section having a shape like an L-shape turned to one side and includes a front surface portion  12   a  and an upper surface portion  12   b.    
     The front surface portion  12   a  of the second frame  12   b  is coupled at the back position of the upper surface portion  11   b  of the first frame  11 . The upper surface portion  11   b  of the first frame  11 , the front surface portion  12   a  of the second frame  12 , and the upper surface  FIG. 12 b    of the second frame constitute the stepped structure. 
     A portion of the second frame  12 , which is on the back side of the upper surface portion  11   b , is connected to the rear cover  3   e.    
     As shown in  FIGS. 3 and 5 , the display unit  13  including the display  2  is connected to the first frame  11  of the upper holding portion  3   a.    
     The display unit  13  has a function of displaying images on the display  2 . 
     The specific configuration of the display unit  13  is not limited. For example, the display  2 , optical elements such as a diffusion plate, backlights, and the like are disposed. LEDs, LDs, or the like are installed as light sources for the backlights. Those devices are held by chassis or the like. The chassis are connected to the first frame  11 . In addition, any configuration may be employed. 
     For example, the control boards  8  and the loudspeakers  9  for low sounds which are shown in  FIG. 2  are disposed on the back side of the chassis or the like included in the display unit  13 . 
     As shown in  FIGS. 3 to 5 , the front surface portion  12   a  of the second frame  12  has a plurality of fins  14  protruding to the front side of the television  1 . Slits  15  are formed between the fins  14 . 
     Moreover, as shown in  FIG. 4 , sound passing holes  16  are formed in the front surface portion  12   a  of the second frame  12 . Therefore, the internal space S 1  and an external space S 2  of the television  1  are in communication with each other through the slits  15  and the sound passing holes  16 . 
     As shown in  FIG. 5 , the loudspeaker box  4   a  is connected to the second frame  12  of the upper holding portion  3   a.    
     As shown in  FIG. 4 , the loudspeaker box  4   a  is connected to the second frame  12  such that upper parts of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds are at the same height as the positions of the slits  15  and the sound passing holes  16 . 
     In other words, the loudspeaker box  4   a  is disposed such a position that the upper parts of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds can be seen through the slits  15  and the sound passing holes  16  as those are viewed from the front side of the television  1 . 
     Sounds output from the tweeter  7   a  and the loudspeakers  7   b  for middle sounds are emitted to the front side of the television  1  through the slits  15  and the sound passing holes  16 . 
     Thus, in this embodiment, there is realized a so-called slit speaker configuration in which the loudspeaker boxes  4  are disposed on the deep side of the slits  15 . Accordingly, the loudspeaker boxes  4  can be less prominent, which improve the design of the television  1 . Moreover, a user who views a picture can concentrate on content displayed on the display  2  and can obtain a high sense of immersion. Moreover, high-quality sounds can be output at a sufficient sound pressure because the loudspeakers  7  with a diaphragm having a larger size can be installed. 
     It should be noted that although it is not shown in  FIG. 5 , the loudspeaker box  4   a  is fixed on the display unit  13  by screwing or the like. Accordingly, the loudspeaker box  4   a  can be sufficiently fixed. 
     As shown in  FIG. 6 , the loudspeaker box  4   a  includes a main body portion  18 , the tweeter  7   a , the loudspeakers  7   b  for middle sounds, and a reflector  19 , and a partition structure  20 . 
     The main body portion  18  generally has a cuboid shape closer to a plate shape. Moreover, the main body portion  18  is configured to be hollow. 
     As shown in  FIGS. 5 and 6 , an upper portion of a front surface portion  18   a  on the front side of the main body portion  18  is recessed backward to form a recess portion  21 . As the recess portion  21  is viewed from the front side, the surface facing the front side is a mounting surface  22 . 
     The tweeter  7   a  and the two loudspeakers  7   b  for middle sounds are disposed on the mounting surface  22  so as to be arranged in the left-and-right direction. 
     The tweeter  7   a  is disposed tilted upward by three degrees with respect to the front surface portion  18   a  of the main body portion  18 . That is, the sound output direction of the tweeter  7   a  is tilted upward by three degrees with respect to the front surface portion  18   a.    
     For example, it is assumed that the front surface portion  18   a  of the main body portion  18  is correctly made to face the front side of the television  1 . In this case, the sound output direction of the tweeter  7   a  is tilted by three degrees with respect to the front direction (the Y direction). 
     As described above, in the present disclosure, the state in which it is disposed such that the output direction is deviated by three degrees is included in the concept of the output side of the tweeter  7   a  “being made to face the front side”. 
     It should be noted that the loudspeakers  7   b  for middle sounds are disposed without being tilted upward. As a matter of course, the loudspeakers  7   b  for middle sounds may also be disposed tilted upward like the tweeter  7   a.    
     Driving boards, power supply boards, and the like of the three loudspeakers  7  are disposed in an internal space S 3  of the main body portion  18 . The illustration and description of the internal configuration of the main body portion  18  are omitted. An arbitrary configuration for driving the three loudspeakers  7  may be used. Moreover, conventional technologies can be used for realizing such a configuration. 
     The portion surrounded by the internal space S 3  of the main body portion  18  also functions as an enclosure for the three loudspeakers  7 . 
     The reflector  19  is disposed at a position opposite to the mounting surface  22 . That is, the reflector  19  is disposed on the sound output side of the loudspeakers  7 . 
     As shown in  FIG. 6 , a bar-like cushion member  19   a  extending to the left and right is configured at an upper end portion of the reflector  19 . This cushion member  19   a  is fixed at left and right end portions of the front surface portion  18   a  of the main body portion  18 . Moreover, the lower end portion of the reflector  19  is connected to the lower end portion of the recess portion  21 , which is formed at the front surface portion  18   a.    
     Therefore, the reflector  19  is positioned to close the recess portion  21  as the loudspeaker box  4   a  is viewed from the front side. 
     Moreover, the reflector  19  is configured to cover and hide center portions and lower portions of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds such that only the upper parts of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds can be seen as the loudspeaker box  4   a  is viewed from the front side. 
     The upper parts of the tweeter  7   a  and the loudspeakers  7   b  for middle sounds, which are shown in  FIG. 4  and which can be seen through the slits  15  and the sound passing holes  16 , are substantially equal to portion not covered and hidden by the reflector  19 . 
     The partition structure  20  is mounted on the tweeter  7   a . The partition structure  20  is configured with respect to the reflector  19  disposed on the sound output side of the tweeter  7   a.    
     [Partition Structure] 
       FIG. 7  is an enlarged diagram in which a portion of the partition structure  20  in the cross-sectional view shown in FIG.  5  is enlarged. 
       FIGS. 8 and 9  are diagrams schematically showing the tweeter  7   a  in which the partition structure  20  is mounted.

       FIGS. 10 and 11  are diagrams schematically showing the partition structure  20 . 
     A of  FIG. 10  is a perspective view as viewed from the front side obliquely. B of  FIG. 10  is a diagram as viewed from the back side. That is, it is a diagram as viewed from the side of the tweeter  7   a  in which the partition structure  20  is mounted. A of  FIG. 11  is a side view as viewed from the right side. B of  FIG. 11  is a plan view as viewed from the upper side. 
     As shown in  FIG. 7 , the reflector  19  is disposed tilted toward the front side of the television  1 . Accordingly, the reflector  19  has a function of efficiently guiding sounds output from the three loudspeakers  7  toward the sound passing holes  16  and the slits  15  formed in the front surface portion  12   a  of the second frame  12 . 
     In this embodiment, with respect to sounds output from the loudspeakers  7   b  for middle sounds in which the partition structure  20  is not mounted, the function of efficiently guiding the sounds toward the sound passing holes  16  and the slits  15  is provided. 
     It should be noted that when the loudspeaker box  4   a  is mounted, the cushion member  19   a  configured at the upper end portion of the reflector  19  is sufficiently pushed and deformed against the front surface portion  11   c  of the first frame  11  of the upper holding portion  3   a  (the illustration of the deformed state is omitted). Accordingly, a clearance is prevented from being formed between the front surface portion  11   c  and the loudspeaker box  4   a . As a result, sounds output from the loudspeakers  7   b  for middle sounds can be efficiently guided toward the sound passing holes  16  and the slits  15 . 
     The reflector  19  forms a gap space S 4  (gray portion) between the reflector  19  and the tweeter  7   a . The gap space S 4  is a space formed between the reflector  19  and the tweeter  7   a  when the reflector  19  is disposed on the sound output side of the tweeter  7   a  (i.e., the front side). 
     Moreover, the gap space S 4  is a space communicating with the external space S 2 . In this embodiment, the gap space S 4  is in communication with the external space S 2  via the internal space S 5 , the sound passing holes  16 , and the slits  15  of the second frame  12 . 
     Moreover, the gap space S 4  has an opening portion P 1  opened toward the side communicating with the external space S 2 . 
     Sounds output from the tweeter  7   a  are emitted toward the external space S 2  from the gap space S 4  through the opening portion P 1 . 
     In this embodiment, the gap space S 4  is a space sandwiched by portions in which the reflector  19  and the tweeter  7   a  overlap each other as the reflector  19  and the tweeter  7   a  are viewed from the sound output side (i.e., the front side) of the tweeter  7   a . The opening portion P 1  is a portion of the gap space S 4  which is at the upper end portion of the reflector  19  (the cushion member  19   a ). 
     That is, as the reflector  19  and the tweeter  7   a  are viewed from the sound output side of the tweeter  7   a , the opening portion P 1  is configured at the position of an end portion of the reflector  19 , the end portion being located on the side of the portion in which the tweeter  7   a  can be seen. 
     It should be noted that the present technology is not limited to the case where the gap space S 4  and the opening portion P 1  are defined in the above-mentioned manner. 
     Arbitrary space and opening portion which correspond to the space formed between the reflector  19  and the tweeter  7   a  and the opening portion on the side of the portion of that space, which is in communication with the external space S 2 , can be the gap space S 4  and the opening portion P 1  according to the present technology. 
     For example, a space up to a plane connecting the upper end portion of the reflector  19  and an upper end portion of the tweeter  7   a  to each other may be used as the gap space S 4  and an opening portion on the side communicating with the external space S 2  may be used as the opening portion P 1 . 
     Alternatively, a space up to a plane extending from the upper end portion of the reflector  19  in the sound output direction of the tweeter  7   a  may be used as the gap space S 4  and an opening portion on the side communicating with the external space S 2  may be used as the opening portion P 1 . 
     Alternatively, a perpendicular line may be drawn from the upper end portion of the reflector  19  toward the tweeter  7   a , a space up to a portion of intersection therebetween may be used as the gap space S 4 , and the opening portion on the side communicating with the external space S 2  may be used as the opening portion P 1 . 
     As shown in  FIGS. 8, 9 , and the like, the tweeter  7   a  includes a diaphragm  25  and a holding member  26 . The holding member  26  holds the diaphragm  25 , the voice coil (not shown), a magnetic circuit, which is constituted by a magnet, a yoke, and the like, and the like. 
     A portion disposed around the diaphragm  25  as the tweeter  7   a  is viewed from the front side is the frame  27 . 
     In this embodiment, the diaphragm  25  has a circular shape as viewed from the front side and the frame  27  also has a ring shape so as to conform to the shape of the diaphragm  25 . 
     It should be noted that the present technology is not limited to the circular and track speaker units, and the present technology can be applied to any shape of loudspeaker unit. Moreover, the output properties of the loudspeaker unit and the like are also not limited, and the present technology can also be applied to a squawker, a woofer, and the like other than the tweeter. 
     In a case where the gap space is formed by disposing an object on the sound output side of the loudspeaker units, the partition structure can be configured with respect to the object. 
     The partition structure  20  is capable of dividing the gap space S 4  into a plurality of spaces. Moreover, the partition structure  20  is capable of guiding sounds output from the tweeter  7   a  toward the opening portion P 1  of the gap space S 4 . That is, the partition structure  20  is capable of guiding sounds output from the tweeter  7   a  toward the external space. 
     The partition structure  20  is integrally formed by injection molding with resin, for example. The resin material is not limited, and any resin material may be used. For example, generally used resins such as ABS (acrylonitrile/butadiene/styrene) resin, engineering plastic such as PC resin and ABS and PC blends, and the like are used. 
     In addition, a material other than the resin material may be used. 
     As shown in  FIG. 7  and the like, the partition structure  20  has a connecting portion  29 , which is connected to the tweeter  7   a , and a plurality of plate-like members  30  to  32 . 
     As shown in  FIGS. 8, 9 , and the like, the connecting portion  29  is connected to a frame disposed around the diaphragm  25  of the tweeter  7   a . Moreover, the connecting portion  29  is held in contact with a portion of the frame  27 , the portion being located on a opposite side to the side of the opening portion P 1  of the gap space S 4 . 
     In this embodiment, the opening portion P 1  is configured at an upper end portion of the gap space S 4 . Therefore, the upper portion of the frame  27  is the portion on the side of the opening portion P 1 . The lower portion of the frame  27  is the portion on the side opposite to the side of the opening portion P 1 . 
     The connecting portion  29  of the partition structure  20  is connected to the lower portion of the frame  27  so as to be held in contact with the frame  27 . Accordingly, sounds output from the tweeter  7   a  are guided toward the opening portion P 1  on the upper side without allowing sounds output from the tweeter  7   a  to leak out downward. 
     As shown in  FIGS. 8 and 9 , the connecting portion  29  is held in contact with the frame  27  to cover more than half of the circular region from the lower side to the upper side of the frame  27 . 
     Therefore, it can also be said that the connecting portion  29  is disposed based on a position opposite to the opening portion P 1  of the gap space S 4 . 
     Otherwise, it can also be said that the connecting portion  29  is connected based on a position of the frame  27  that is furthest from the opening portion P 1 . In this embodiment, a lowermost end position of the frame  27  corresponds to the position furthest from the opening portion P 1 . 
     In any case, it is sufficient that the connecting portion  29  is configured and connected to the frame  27  such that sounds output from the tweeter  7   a  can be guided toward the opening portion P 1  on the upper side without allowing sounds output from the tweeter  7   a  to leak out downward. 
     It should be noted that the connecting portion  29  of the partition structure  20  may be connected to the portion other than the frame  27  of the holding member  26 . 
     The plurality of plate-like members  30  to  32  has a plate shape. The plate shape is not limited to the planar shape, and also has a plate shape with a curved surface like a bent plate. 
     Moreover, the plurality of plate-like members  30  to  32  is disposed in the gap space S 4 . It should be noted that being disposed in the gap space S 4  includes a state in which at least parts of the plate-like members  30  to  32  are included in the gap space S 4 . 
     Moreover, the plurality of plate-like members  30  to  32  extends toward the opening portion P 1  of the gap space S 4  and is configured to guide sounds output from the tweeter  7   a  toward the external space S 2 . 
     As shown in  FIG. 7  and the like, in this embodiment, the three plate-like members  30  to  32  are configured. The plate-like members  30  to  32  have a planar shape and are disposed tilted forward. That is, the plate-like members  30  to  32  are disposed to have upper end portions  30   a  to  32   a  located more forward than lower end portions  30   b  to  32   b . Moreover, the upper end portions  30   a  to  32   a  are aligned at the position of the opening portion P 1 . 
     Moreover, the plate-like members  30  to  32  are configured to be parallel to each other inside the gap space S 4 . The plate-like members  30  to  32  are configured integrally with the connecting portion  29 . 
     The plate-like members  30  to  32  divide the gap space S 4  into the plurality of spaces. For example, a divided space S 6  is formed between the plate-like members adjacent to each other. 
     In the sound output direction of the tweeter  7   a , a plate-like member  30  that is disposed at the position furthest from the tweeter  7   a  and the end portion (the lower end portion)  30   b  on the side of the tweeter  7   a  is coupled to the connecting portion  29 . 
     Moreover, as shown in B of  FIG. 8 , the plate-like member  30  is configured to cover and hide the diaphragm  25  in the region from the position of the connecting portion  29  (the position furthest from the opening portion P 1 ) to the end portion on the side of the opening portion P 1  as the diaphragm  25  is viewed from the sound output side of the tweeter  7   a.    
     Accordingly, sounds output from the tweeter  7   a  can be efficiently guided toward the opening portion P 1  on the upper side without allowing sounds output from the tweeter  7   a  to leak out downward. 
     Regarding the plate-like members  31  and  32  that are disposed closer to the tweeter  7   a  than the plate-like member  30 , clearances are formed between the end portions (the lower end portions)  31   b  and  32   b  on the side of the tweeter  7   a  and the connecting portion  29 . 
     The sizes of the plate-like members  31  and  32  in the left-and-right direction are set such that the plate-like members  31  and  32  can cover and hide the diaphragm  25  as in the plate-like member  30 . 
     As those are schematically shown with the arrows in  FIG. 7 , sounds output from the tweeter  7   a  pass through the divided space S 6  and are guided toward the opening portion P 1  of the gap space S 4 . The sounds guided to the gap space S 4  are emitted into the external space S 2  through the internal space S 5 , the sound passing holes  16 , and the slits  15  of the second frame  12 . 
     It should be noted that the space between the plate-like member  32  disposed at the position closest to the tweeter  7   a  and the tweeter  7   a  is also included in the divided space S 6 . 
     In this embodiment, as the reflector  19  and the tweeter  7   a  are viewed from the sound output side of the tweeter  7   a  as described above, the reflector  19  is disposed to cover and hide a part of the diaphragm  25 . The plurality of plate-like members  30  to  32  is configured to be capable of guiding sounds output from the tweeter  7   a  toward the visible part of the diaphragm  25 . 
       FIG. 12  is a graph showing frequency characteristics of a sound pressure level depending on with or without the partition structure  20 . As in the television  1 , a loudspeaker capable of outputting sounds in the range of 500 Hz to 20 kHz with a slit speaker configuration was prepared. Then, a sound pressure level in a case where the partition structure  20  is mounted in the loudspeaker and a sound pressure level in a case where the partition structure  20  is not mounted in the loudspeaker are measured at the position spaced away from the loudspeaker by one meter. 
     As shown in  FIG. 12 , an improvement by about 10 dB or more was found in the range of approximately 4 kHz to 8 kHz. 
     In a case where the partition structure  20  shown in  FIG. 7  and the like is not mounted, the reflector  19  collectively reflects the energy of sounds output from the loudspeaker. Therefore, a problem in that the sound pressure greatly attenuates especially in the high range in which sounds more tend to exhibit straight traveling properties can arise. Moreover, a problem in that strong peaks/dips are caused by a resonance in the gap space S 4  between the loudspeaker and the reflector  19  and the frequency characteristics are significantly degraded can also arise. In this embodiment, peaks/dips were caused at several kHz because lengths of reflection paths on which sounds travel the gap space S 4  while undergoing reflection match wavelengths of frequencies in the reproduction frequency range of the tweeter. 
     In contrast, the provision of the partition structure  20  can divide the gap space S 4  into the plurality of spaces. 
     Accordingly, the energy of sounds reflected by the plate-like members  30  to  32  can be dispersed. As a result, the attenuation of the sound pressure can be sufficiently reduced also in the high range in which sounds more tend to exhibit straight traveling properties. 
     Moreover, the influence of a resonance in the gap space S 4  can also be reduced. That is, the frequencies at which peaks/dips are caused can be increased to higher frequencies because reflection paths on which sounds travel the divided space S 6  while undergoing reflection is shortened. In this embodiment, the frequencies at which peaks/dips are caused can be increased to 10 kHz or more as shown in  FIG. 12 . As a result, the frequency characteristics can be improved in the range of about 4 kHz to 8 kHz that corresponds to the reproduction frequency range of the tweeter  7   a.    
     As shown in B of  FIG. 8 , in this embodiment, the plate-like members  30  to  32  are disposed to cover and hide the diaphragm  25 , specifically, the region from the lower portion to the upper portion of the diaphragm  25 . With this configuration, it was possible to sufficiently reduce sounds that reach the reflector  19  and a high effect was obtained. 
     Moreover, as shown in  FIG. 7  and the like, in this embodiment, the three plate-like members  30  to  32  are disposed tilted forward. Accordingly, sounds output from the tweeter  7   a  can be efficiently guided to the opening portion P 1 , and the attenuation of the sound pressure level can be reduced. 
     Moreover, as shown in  FIGS. 7, 8 , and the like, in this embodiment, the divided space S 6  is configured to be opened in the left-and-right direction orthogonal to the extending direction of the plate-like members  30  to  32 , i.e., the direction in which the plate-like members  30  to  32  extend toward the opening portion P 1  from the tweeter  7   a . That is, the left and right side surface sides of the partition structure  20  are not closed but opened. Accordingly, it is possible to sufficiently reduce peaks and the like caused by a resonance occurring in the divided space S 6  divided by the plate-like members  30  to  32 . 
     Moreover, as shown in A and B of  FIGS. 8 and 9  and the like, the partition structure  20  has a reinforcing rib  35  formed at the center portion. The plate-like members  30  to  32  are connected to each other through this reinforcing rib  35 . Accordingly, the rigidity of the partition structure  20  (the rigidity of each plate-like member) can be enhanced. Moreover, cutouts  36  are formed in the plate-like member  31  for reinforcing a mold. 
     Employing the partition structure  20  also for the other loudspeaker boxes  4  shown in  FIGS. 1 and 2  provides similar effects. It should be noted that the loudspeaker boxes  4  and the partition structure  20  do not need to all have the same configurations, and may be designed as appropriate. 
     In this embodiment, the television  1  corresponds to the embodiment of the electronic apparatus. 
     The loudspeaker boxes  4  corresponds to the loudspeaker apparatus. 
     The tweeter  7   a  corresponds to a loudspeaker that outputs sounds. Moreover, the tweeter  7   a  has a loudspeaker portion and a structure and is also an embodiment of the loudspeaker according to the present technology. The portion constituting the loudspeaker unit described above corresponds to the loudspeaker portion. 
     The partition structure  20  corresponds to the structure configured with respect to an object that is disposed on the sound output side of the loudspeaker and forms a gap space communicating with the external space between the object and the loudspeaker. 
     The reflector  19  corresponds to an object that is disposed on a sound output side of the loudspeaker and forms, between the object and the loudspeaker, a gap space communicating with an external space. 
     The plurality of plate-like members  30  to  32  corresponds to one or more plate-like members. 
     The plate-like member  30  corresponds to a first member. 
     The plate-like members  31  and  32  correspond to one or more second members. 
     As described above, the loudspeaker boxes  4  according to this embodiment includes the partition structure  20  configured with respect to the reflector  19  disposed on the sound output side of the tweeter  7   a . The partition structure  20  includes the plurality of plate-like members  30  to  32  that is disposed in the gap space S 4  between the reflector  19  and the tweeter  7   a  and guides sounds output from the tweeter  7   a  into the external space S 2  from the gap space S 4 . Accordingly, it is possible to prevent the sound quality from being affected while employing the configuration to cover and hide the sound output side of the tweeter  7   a . As a result, a high-quality and sufficient sound pressure can be output without degrading the design. 
     For example, it is possible to output high-quality sounds while employing a structure having a narrower aperture for emitting sounds than the area of the diaphragm  25 . For example, realizing the slit speaker configuration or the like makes it possible to perform front emission and in particular to ensure the quality in the high audio range without degrading the design. Moreover, the sound quality is not easily affected by the installation environment because it is unnecessary to emit sounds to the front side through a reflection. Moreover, the loudspeaker boxes  4  can be disposed on the upper side of the set. 
     Moreover, it is possible to prevent attenuation of sounds in the high range, which would be difficult to be ensured in a case where an obstacle is present in front of the diaphragm  25 , because the partition structure  20  divides and causes sound waves to flow obliquely. Moreover, deterioration of frequency characteristics due to a resonance can be prevented because frequencies at which a resonance occurs can be increased to a significantly high frequency due to the division of the gap space S 4 . 
     &lt;Other Embodiments&gt; 
     The present technology is not limited to the above-mentioned embodiments, and various other embodiments can be realized. 
     In the above-mentioned embodiments, as shown in  FIG. 7  and the like, the plate-like members  30  to  32  are configured inside the gap space S 4 . In other words, the plate-like members  30  to  32  are configured such that the whole of the plate-like members  30  to  32  is included in the gap space S 4 . However, the present technology is not limited to such a configuration. 
       FIGS. 13 to 16  are schematic diagrams showing configuration examples of a partition structure according to another embodiment. 
     In a partition structure  220  shown in  FIGS. 13 and 14 , five plate-like members  230  to  234  are configured. Those plate-like members  230  to  234  are not parallel to each other and are configured to have different angles of inclination. 
     Moreover, plate-like members  231  to  233  have upper end portions  231   a  to  233   a  to protrude outward from the opening portion P 1  of the gap space S 4 . Moreover, the whole of a plate-like member  234  is disposed outside the gap space S 4 . Accordingly, sounds output from the tweeter  7   a  can be efficiently guided to the opening portion P 1  and the external space S 2 . 
     Five plate-like members  230  to  234  are configured in a partition structure  320  shown in  FIGS. 15 and 16 . Three upper plate-like members  332  to  334  of those plate-like members  330  to  234  are configured to be parallel to each other. The plate-like members  330  and  331  are configured to have angles of inclination different from those plate-like members  332  to  334 . Moreover, the plate-like members  330  and  331  are configured to have angles of inclination different from each other. 
     Moreover, the plate-like member  332  has an upper end portion  332   a  protruding outward from the opening portion P 1  of the gap space S 4 . Moreover, the whole of the plate-like members  333  and  334  is disposed outside the gap space S 4 . In addition, the uppermost plate-like member  334  is connected to the frame  27  of the tweeter  7   a . That is, in the partition structure  320 , the plate-like members  330  to  334  are disposed to cover the whole of the diaphragm  25 . 
     Accordingly, sounds output from the tweeter  7   a  can be efficiently guided to the opening portion P 1  and the external space S 2 . 
     The example in which the reflector  19  provided in the loudspeaker boxes  4  corresponds to an “object” according to the present technology has been shown above. That is, the example in which a “loudspeaker apparatus” according to the present technology includes the “object”. 
     The present technology is not limited thereto, and the present technology can also be applied in a case where the “object” is a part of an “electronic apparatus” in which the “loudspeaker apparatus” is installed. That is, the “object” may be disposed on the sound output side of the loudspeaker in a state in which the “loudspeaker apparatus” is incorporated in the “electronic apparatus”. 
     For example, it is assumed that the reflector  19  is not provided in the loudspeaker boxes  4  shown in  FIG. 6 . It is also assumed that components and the like of the television  1  are disposed on the sound output side of the tweeter  7   a  when those loudspeaker boxes  4  are incorporated in the television  1 . For example, it is also assumed that the front surface portion  11   c  of the first frame  11  shown in  FIG. 7  is disposed on the front side of the tweeter  7   a  and covers and hides a part of the tweeter  7   a.    
     Also in such a case, a “structure” according to the present technology can be configured with respect to, for example, the front surface portion  11   c  disposed on the front side of the tweeter  7   a.    
     That is, the present technology can be carried out both in a case where the “loudspeaker apparatus” includes the “object” and in a case where the “loudspeaker apparatus” does not include the “object”. 
     Hereinabove, the plurality of plate-like members is disposed as the “structure” according to the present technology. The present technology is not limited thereto, and the effects can be provided also in a case where a single plate-like member is disposed. For example, the “structure” may be constituted only by a “first member” according to the present technology. 
     The angles of inclination of the plate-like members with respect to the sound output direction of the loudspeakers are not limited. For example, the plate-like members may be disposed along the direction orthogonal to the sound output direction. 
     The end portions of the plate-like members, which are on the side of the upper end portion (the opening portion), may be configured to be inclined to one of the left and right as the plate-like members are viewed from the front side. For example, the upper end portions of the plate-like members are configured to be oblique in accordance with the positions at which the loudspeaker units are disposed. Accordingly, the sound directivity properties can be controlled. 
     As also described above, the application of the present technology is not limited to the tweeter. The structure can be mounted in a loudspeaker for an arbitrary reproduction frequency range. 
     Electronic apparatuses to which the present technology can be applied are not limited to televisions. Moreover, the electronic apparatuses to which the present technology can be applied is not limited to an electronic apparatus capable of displaying pictures. For example, the present technology can be applied to any electronic apparatus including portable phones, smartphones, personal computers, game consoles, digital cameras, audio devices, TVs, projectors, car navigation systems, wearable information devices (eyeglass-type, wristband-type), operation devices such as remote controllers, IoT devices connected to the Internet or the like, and the like. 
     The electronic apparatus, the respective configurations such as the loudspeaker boxes, the loudspeakers (the loudspeaker units), the structure, the manufacturing method for the structure, and the like, which have been described with reference to each of the drawings, are the embodiments, and can be arbitrarily modified without departing from the gist of the present technology. That is, any other configurations, manufacturing methods, and the like for carrying out the present technology may be employed. 
     In the present disclosure, the concepts, which define the shape, the size, the positional relationship, the state, and the like, such as “center”, “middle”, “uniform”, “equal”, “the same”, “orthogonal”, “parallel”, “symmetric”, “extending”, “axis direction”, “columnar shape”, “cylindrical shape”, “ring shape”, and “annular shape”, are concepts including “substantially center”, “substantially middle”, “substantially uniform”, “substantially equal”, “substantially the same”, “substantially orthogonal”, “substantially parallel”, “substantially symmetric”, “substantially extending”, “substantially the axis direction”, “substantially the columnar shape”, “substantially the cylindrical shape”, “substantially the ring shape”, “substantially the annular shape”, and the like. 
     For example, the concepts also include states falling within a predetermined range (e.g., range of ± 10   9   6 ) based on “completely center”, “completely middle”, “completely uniform”, “completely equal”, “completely the same”, “completely orthogonal”, “completely parallel”, “completely symmetric”, “completely extending”, “completely axis direction”, “completely columnar shape”, “completely cylindrical shape”, “completely ring shape”, “completely annular shape”, and the like. 
     At least two of the features of the present technology described above can also be combined. In other words, various features described in the respective embodiments may be arbitrarily combined across the respective embodiments. Moreover, the various effects described above are merely illustrative, not limitative, and other effects may be provided. 
     It should be noted that the present technology can also take the following configurations.
