FIELD OF THE INVENTION
[0001] The present disclosure relates to a display unit suitable for a thin television or the like.

BACKGROUND
[0002] In recent years  a display unit for various broadcast waves  video images  and the like has been increased in size and decreased in thickness. Therefore  it has been demanded to realize a configuration in which an image display region is widened  a region other than the display region (frame region) is narrowed  and a thickness of a housing is decreased. In other words  in the display unit  it has been desired to narrow the frame and thin the thickness thereof.
[0003] Further  in an existing display unit  a speaker unit is housed in a housing of a main body section (display main body section). In these days  a display unit in which a speaker box including such a speaker unit is removably attached to a main body section has been proposed (for example  see Japanese Unexamined Patent Application Publication No. 2004-363952).

STATEMENT OF THE INVENTION
[0004] According to an embodiment of the present disclosure  there is provided a display unit including: a main body section including a first front surface  a first rear surface  and a first side surface; one or a plurality of speaker boxes each including one or a plurality of speaker units and a housing containing the one or a plurality of speaker units  the one or a plurality of speaker boxes being selectively attachable with respect to one of the first side surface and the first rear surface in the main body section; and one or a plurality of attaching members commonly used for both at the time of attaching the one or a plurality of speaker boxes to the first side surface and at the time of attaching the one or a plurality of speaker boxes to the first rear surface.

OBJECT OF THE INVENTION
[0005] The principal object according to an embodiment of the present invention is to provide a display unit capable of decreasing a cost of members while improving usability of a user.

SUMMARY
[0006] In the display unit including the foregoing removable speaker box  aspects of attaching the speaker box to the main body section are allowed to be various. Therefore  usability of a user (viewer) is possibly improved.
[0007] However  in some cases  according to a method of attaching the speaker box  in exchange for improved usability  it may result in the high cost (increased cost of members). Therefore  a proposal of a method capable of decreasing a cost of members while improving usability of a user is desired.
[0008] It is desirable to provide a display unit capable of decreasing a cost of members while improving usability of a user.
[0009] According to an embodiment of the present disclosure  there is provided a display unit including: a main body section including a first front surface  a first rear surface  and a first side surface; one or a plurality of speaker boxes each including one or a plurality of speaker units and a housing containing the one or a plurality of speaker units  the one or a plurality of speaker boxes being selectively attachable with respect to one of the first side surface and the first rear surface in the main body section; and one or a plurality of attaching members commonly used for both at the time of attaching the one or a plurality of speaker boxes to the first side surface and at the time of attaching the one or a plurality of speaker boxes to the first rear surface.
[0010] In the display unit according to the embodiment of the present disclosure  the speaker box is selectively attachable with respect to one of the first side surface and the first rear surface in the main body section. Thereby  variety of aspects of attaching the speaker box to the main body section according to usage aspects of the display unit (for example  arrangement type such as stationary type and wall-hanging type)  usage purposes (for example  a purpose with a high regard for design such as realizing a narrowed frame  a purpose with a high regard for sound quality outputted from the speaker unit  and the like)  and the like is realized. Further  in attaching the speaker box to the main body section  the single attaching member is commonly used for both at the time of attachment to the first side surface and at the time of attachment to the first rear surface (the attaching member is shared). Thereby  for example  differently from in a case in which separate (individual or exclusive) attaching members are used at the time of attachment to the first side surface and at the time of attachment to the first rear surface  a member (attaching member) not used (unnecessary) at the time of each attachment does not exist.
[0011] In the display unit according to the embodiment of the present disclosure  the speaker box is selectively attachable with respect to one of the first side surface and the first rear surface in the main body section. In addition  the attaching member is commonly used for both at the time of attachment to the first side surface and at the time of attachment to the first rear surface. Therefore  while variety of aspects of attaching the speaker box to the main body section is realized  a member unnecessary at the time of the respective attachment works is allowed to be omitted. Therefore  while usability of a user is improved  cost of members is allowed to be decreased.
[0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary  and are intended to provide further explanation of the technology as claimed.

[Embodiment]
[Configuration of Display Unit 1]
[0025] FIG. 1 schematically illustrates an outline configuration of a display unit (display unit 1) according to an embodiment of the present disclosure. The display unit 1 is  for example  used as a thin television  and has a configuration in which a flat main body section (display main body section) 2 for displaying an image is supported by a stand 3. The display unit 1 further includes a speaker box 4  and one attaching member 5 and two attaching screws 6A and 6B that are used for attaching the speaker box 4 to the main body section 2. The display unit 1 is used as a stationary (table top) type display unit laid on a horizontal surface such as a floor  a shelf  and a table in a state that the stand 3 is attached to the main body section 2. In addition  the display unit 1 may be used as a wall-hanging type display unit in a state that the stand 3 is removed from the main body section 2. In FIG. 1  a cross-sectional configuration example of a region indicated by referential symbol P1 (region on a lower surface S23 side out of side surfaces in the main body section 2) is schematically illustrated.
[Main Body Section 2]
[0026] The main body section 2 has  for example  a front surface plate 21  a display panel 22  an electronic substrate (control-part substrate) 23  electronic parts (control parts) 24  and a rear cover (rear surface cover) 25 sequentially from a front surface S21 (first front surface) side (viewer side) to a rear surface S22 (first rear surface) side. The main body section 2 further has a frame (bezel) 26 on the periphery (frame region) of the front surface plate 21 and the whole side surface (first side surface) of the main body section 2. In the following description  as illustrated in FIG. 1 and the like  the horizontal direction (longitudinal direction in the display surface in the main body section 2) is referred to as X-axis direction  the vertical direction (short-axis direction in the display surface in the main body section 2) is referred to as Y-axis direction  and the thickness (depth) direction in the main body section 2 is referred to as Z-axis direction.
[0027] The front surface plate 21 is made of  for example  a transparent plate glass or the like. A viewer is able to view an image displayed on the display panel 22 through the front surface plate 21. In some cases  the front surface plate 21 may be omitted.
[0028] The display panel 22 is provided on the rear surface side of the front surface plate 21. The display panel 22 is formed by  for example  using a liquid crystal display device. It is to be noted that instead of such a liquid crystal display device  other display device such as a plasma display device  an organic EL (electro luminescence) display device  an inorganic EL display device  an electrodeposition display device  and an electrochromic display device may be used for the display panel 22.
[0029] The electronic substrate 23 is a substrate mounted with the electronic parts 24 formed of a control IC (integrated circuit) such as a microcomputer  a power source IC  a resistance element  a capacitative element  or the like. A given circuit is formed on the electronic substrate 23 through a printed wiring or the like. The electronic parts 24 on the electronic substrate 23 are electrically connected to the display panel 22 directly or indirectly through a not-shown wiring or the like.
[0030] The rear cover 25 is arranged on the rear surface side (the most rear surface of the main body section 2) of the electronic substrate 23 and the electronic parts 24. The rear cover 25 is made of a resin material such as an ABS resin (acrylonitrile-butadiene-styrene resin)  PS (polystyrene)  a resin material obtained by adding the ABS resin to a PC resin (polycarbonate resin)  or a resin material obtained by adding PPE (polyphenylene ether) to PS. Instead of the foregoing resin materials  for example  the rear cover 25 may be made of a metal material such as iron  aluminum  and stainless steel  and for example  a coated steel plate  a laminated steel plate  a hairline-finished plate  or the like may be used for the rear cover 25.
[0031] In the rear cover 25 (the rear surface S22 of the main body section 2)  two types of screw holes 251 and 252 (through holes) are provided. The screw hole 251 (first main body screw hole) is arranged on upper side (positive side in the Y-axis direction) on the rear surface S22 than the screw hole 252 (second main body screw hole). The screw hole 251 is a screw hole selectively used in attaching the speaker box 4 to the rear surface S22. Meanwhile  the screw hole 252 is arranged on lower side (negative side in the Y-axis direction) on the rear surface S22 than the screw hole 251. The screw hole 252 is a screw hole selectively used in attaching the speaker box 4 to the lower surface S23. Details of aspects of attaching the speaker box 4 will be described later (FIG. 6A to FIG. 8B).
[Speaker Box 4]
[0032] FIG. 2 is a perspective view of an appearance configuration of the speaker box 4. The speaker box 4 has  as illustrated in FIG. 1 and FIG. 2  a speaker unit 40 and a housing (package member) 41 to contain (house) the speaker unit 40. As described later  the speaker box 4 is selectively attachable with respect to one of the lower surface S23 and the rear surface S22 in the main body section 2.
[0033] The speaker unit 40 is a member that outputs sound (including music  sound effect  and the like) to the outside (sound output section). As illustrated in FIG. 2  as an example  two speaker units 40 for outputting right-use sound and left-use sound are arranged along the X-axis direction (longitudinal direction of the housing 41).
[0034] In this case  the housing 41 is in the shape of a rectangle with the X-axis direction as its longitudinal direction. The housing 41 has a front surface S44 (second front surface)  a rear surface S41 (second rear surface)  and a side surface (second side surface) including an upper surface S43 and a lower surface S42 that are defined by arrangement direction of the speaker unit 40. In other words  the surface on the side from which sound is outputted from the speaker unit 40 is defined as the front surface S44  and the surface opposed to the front surface S44 is defined as the rear surface S41.
[0035] In the housing 41  holes (two types of holes) used in attaching the speaker box 4 to the main body section 2 are provided respectively in the rear surface S41 and the lower surface S42. Specifically  in the rear surface S41  an attaching hole 421 (first attaching hole) formed by sinking the housing 41 itself into the internal side and a screw hole 431 (first speaker screw hole) as a hole with respect to the housing 41 are provided. Further  similarly  in the lower surface S42  an attaching hole 422 (second attaching hole) formed by sinking the housing 41 itself into the internal side and a screw hole 432 (second speaker screw hole) as a hole with respect to the housing 41 are provided. It is to be noted that as illustrated in FIG. 2  in this case  three (three pairs) of the attaching holes 421 and 422 and the screw holes 431 and 432 are respectively provided along the X-axis direction. However  the number of holes is not limited thereto  and one pair thereof  two pairs thereof  or four or more pairs thereof may be provided.
[Attaching Member 5]
[0036] FIG. 3 is a perspective view of an appearance configuration of the attaching member 5. Though described in detail later  the attaching member 5 is a member commonly used (shared) for both at the time of attaching the speaker box 4 to the lower surface S23 of the main body section 2 and at the time of attaching the speaker box 4 to the rear surface S22 of the main body section 2 (common attaching member). The attaching member 5 is made of  for example  a material such as a resin  iron  aluminum  and stainless steel. The attaching member 5 includes a flat connection section 5A (first connection section) extending along the Y-axis direction and a flat connection section 5B (second connection section) bent to be substantially perpendicular to the connection section 5A. In other words  the attaching member 5 is in the shape of L bent so that the connection sections 5A and 5B are substantially perpendicular to each other.
[0037] Though described in detail later  the connection section 5A is a connection section (attaching section) used for both connecting with the main body section 2 side and connecting with the speaker box 4 side. The connection section 5A has two screw holes 51 and 52 (through holes) along the Y-axis direction. The screw hole 51 (first member screw hole) is arranged farther from the connection section 5B side (negative side in the Y-axis direction) than the screw hole 52 (second member screw hole). The screw hole 51 is a screw hole used for both attaching the speaker box 4 to the lower surface S23 of the main body section 2 and attaching the speaker box 4 to the rear surface S22 of the main body section 2. Meanwhile  the screw hole 52 is a screw hole selectively used for attaching the speaker box 4 to the lower surface S23 of the main body section 2.
[0038] Though described in detail later  the connection section 5B is a connection section (attaching section) selectively used for connecting with the speaker box 4 side. The connection section 5B has one screw hole 53 (through hole  third member screw hole). The screw hole 53 is a screw hole selectively used for attaching the speaker box 4 to the rear surface S22 of the main body section 2.
[Attaching Screws 6A and 6B]
[0039] Though described in detail later  the attaching screws 6A and 6B are screws respectively used for attaching the speaker box 4 to the lower surface S23 or the rear surface S22 of the main body section through the attaching member 5. Specifically  the attaching screws 6A and 6B are fastened by using the screw holes 251 and 252 in the rear cover 25  the screw holes 431  432  and the like in the housing 41  and the screw holes 51  52  and 53 in the attaching member 5  and thereby the foregoing attachment (fixation) is made.
[Function and Effect of Display Unit 1]
[1. Basic Operation]
[0040] In the display unit 1  according to control by the respective electronic parts 24 on the electronic substrate 23  display operation is made in respective pixels (display devices) on the display panel 22  and an image is displayed. The image displayed on the display 22 as above is allowed to be viewed by a user (viewer) on the front surface S21 side of the main body section 2 through the front surface plate 21. Further  for example  according to control by the respective electronic parts 24 on the electronic substrate 23  sound is outputted from the respective speaker units 40 in the speaker box 4  and the user is able to listen to the sound.
[2. Aspects of Attaching Speaker Box 4]
[0041] Next  a description will be given in detail of aspects of attaching the speaker box 4 (arrangement aspects of the speaker unit 40) as one of the characteristics according to the embodiment of the present disclosure in comparison to comparative examples (Comparative examples 1 and 2).
[2-1. Comparative Example 1]
[0042] FIGs. 4A and 4B schematically illustrate part of cross-sectional configurations of display units (display units 101A and 101B) according to Comparative example 1. FIG. 4A illustrates the cross-sectional configuration of the display unit 101A  and FIG. 4B illustrates the cross-sectional configuration of the display unit 101B respectively. The display units 101A and 101B according to Comparative example 1 respectively house the speaker unit 40 in main body sections 102A and 102B (in this case  in end region on the lower surface S23 side in the main body sections 102A and 102B).
[0043] Specifically  in the display unit 101A illustrated in FIG. 4A  the speaker unit 40 is housed on the lower side of the display panel 22 so that sound Sout is outputted in the lower direction (negative side in the Y-axis direction). Therefore  in the display unit 101A  while a width W101A of the frame region is relatively large  a thickness (depth) T101A of the main body section 102A is relatively small. Therefore  the display unit 101A has a configuration suitable as what we call wall-hanging type that is a usage aspect with a high regard for realizing a thinned display unit.
[0044] Meanwhile  in the display unit 101B illustrated in FIG. 4B  the speaker unit 40 is housed on the rear surface side of the display panel 22  the electronic substrate 23  the electronic parts 24  and the like so that the sound Sout is outputted in the lower direction. Therefore  in the display unit 101B  while a width W101B of the frame region is relatively small  a thickness T101B of the main body section 102A is relatively large. Therefore  the display unit 101B has a configuration suitable as what we call stationary type that is a usage aspect with a high regard for realizing a narrowed frame.
[0045] As described above  the display units 101A and 101B according to Comparative example 1 have the configurations in which the usage aspects (for example  arrangement type such as stationary type and wall-hanging type) and the like are previously fixed. Therefore  usability of a user is degraded.
[2-2. Comparative Example 2]
[0046] FIGs. 5A and 5B schematically illustrate part of cross-sectional configurations of a display unit (display unit 201) according to Comparative example 2. The display unit 201 according to Comparative example 2 includes a main body section 202  a speaker box 204 housing the speaker unit 40  two (two types of) attaching members 205A and 205B  and the two attaching screws 6A and 6B.
[0047] In Comparative example 2  differently from in Comparative example 1 mentioned above  the speaker box 204 is selectively attachable with respect to one of the lower surface S23 and the rear surface S22 in the main body section 202.
[0048] Specifically  in the example illustrated in FIG. 5A  the speaker box 204 is attached to the lower surface S23 of the main body section 202 so that the lower surface S23 of the main body section 202 is contacted with the rear surface S41 of the housing 41  and the sound Sout is outputted in the lower direction. At this time  more specifically  the attaching screw 6A is fastened on to the rear cover 25 of the main body section 202 through the flat attaching member 205A used exclusively for attachment to the lower surface S23  and the attaching screw 6B is fastened on to the lower surface S42 of the housing 41 in the speaker box 204  and thereby the foregoing attachment is made. In this case  in the display unit 201  a thickness T201A of the main body section 202 is relatively small. Therefore  the display unit 201 has a configuration suitable as wall-hanging type that is a usage aspect with a high regard for realizing a thinned display unit.
[0049] Meanwhile  in the example illustrated in FIG. 5B  the speaker box 204 is attached to the rear surface S22 of the main body section 202 so that the rear surface S22 of the main body section 202 is contacted with the upper surface S43 of the housing 41  and the sound Sout is outputted in the lower direction. At this time  more specifically  the attaching screw 6A is fastened on to the rear cover 25 of the main body section 202 through the L-shaped attaching member 205B used exclusively for attachment to the rear surface S22  and the attaching screw 6B is fastened on to the rear surface S41 of the housing 41 in the speaker box 204  and thereby the foregoing attachment is made. In this case  in the display unit 201  a width W201B of the frame region is relatively small. Therefore  the display unit 201 has a configuration suitable as stationary type that is a usage aspect with a high regard for realizing a narrowed frame.
[0050] As described above  in the display unit 201 according to Comparative example 2  differently from in Comparative example 1 mentioned above  the usage aspects (for example  arrangement type such as stationary type and wall-hanging type) and the like are allowed to be adjusted according to the aspects of attaching the speaker box 204 to the main body section 202. Therefore  variety of aspects of attaching the speaker box 204 to the main body section 202 according to usage aspects of the display unit 201 and the like is realized  and usability of a user is allowed to be more improved than in Comparative example 1 mentioned above.
[0051] However  in Comparative example 2  as described above  at the time of attachment to the lower surface S23 of the main body section 202 and at the time of attachment to the rear surface S22 of the main body section 202  separate (individual or exclusive) attaching members 205A and 205B are used. Therefore  at the time of each attachment  a member (the attaching member 205A or the attaching member 205B) not used (unnecessary) exists. Accordingly  two types of attaching members are necessitated  and cost of members is increased by just that much.
[2-3. Function of Embodiment]
[0052] Meanwhile  in the display unit 1 according to this embodiment  as illustrated in FIG. 1 to FIG. 3  first  as in Comparative example 2 mentioned above  the speaker box 4 is selectively attachable with respect to one of the lower surface S23 and the rear surface S22 in the main body section 2. Thereby  variety of aspects of attaching the speaker box 4 to the main body section 2 according to usage aspects of the display unit 1 (for example  arrangement type such as stationary type and wall-hanging type) and usage purposes (for example  a purpose with a high regard for design such as realizing a narrowed frame  a purpose with a high regard for sound quality outputted from the speaker unit 40  and the like) is realized.
[0053] Further  in attaching the speaker box 4 to the main body section 2  the single attaching member 5 (and the attaching screws 6A and 6B) is commonly used (shared) for both at the time of attachment to the lower surface S23 and at the time of attachment to the rear surface S22. Thereby  differently from in Comparative example 2 mentioned above in which the attaching member used at the time of attachment to the lower surface S23 is different from that used at the time of attachment to the rear surface S22  at the time of each attachment  a member (attaching member) not used (unnecessary) does not exist. In other words  at the time of each attachment  it is enough to use the single attaching member 5.
[0054] A description will be given in detail of usage aspects of the display unit 1 (aspects of attaching the speaker box 4) with reference to FIG. 6A to FIG. 8B.
[First Usage Aspect]
[0055] First  in a first usage aspect illustrated in FIGs. 6A and 6B  the speaker box 4 is attached to the lower surface S23 of the main body section 2 so that the lower surface S23 of the main body section 2 is contacted with the rear surface S41 of the housing 41  and the sound Sout is outputted in the lower direction. At this time  more specifically  the attaching screw 6A is fastened by using the screw hole 51 in the attaching member 5 and the screw hole 252 in the rear cover 25 of the main body section 2  and thereby the rear surface S22 in the main body section 2 and the connection section 5A in the attaching member 5 are connected with each other. Further  the attaching screw 6B is fastened by using the screw hole 52 in the attaching member 5 and the screw hole 432 in the housing 41 of the speaker box 4  and thereby the lower surface S42 in the housing 41 of the speaker box 4 and the connection section 5A in the attaching member 5 are connected with each other. Further  the connection section 5B in the attaching member 5 is inserted into the attaching hole 422 in the housing 41 of the speaker box 4  and thereby the lower surface S42 in the housing 41 of the speaker box 4 and the connection section 5B in the attaching member 5 are connected with each other.
[0056] In the first usage aspect  in the display unit 1  a thickness T1 of the main body section 2 is relatively small. Therefore  the first usage aspect has a configuration suitable as wall-hanging type that is a usage aspect with a high regard for realizing a thinned display unit. Further  the sound Sout from the speaker unit 40 is outputted in the lower direction (the sound Sout is not outputted to the user side). Therefore  the first usage aspect has a configuration with a high regard for design more than sound.
[Second Usage Aspect]
[0057] Meanwhile  in a second usage aspect illustrated in FIGs. 7A and 7B  the speaker box 4 is attached to the lower surface S23 of the main body section 2 so that the lower surface S23 of the main body section 2 is contacted with the upper surface S43 of the housing 41  and the sound Sout is outputted to the user side (positive side in the Z-axis direction). At this time  more specifically  the attaching screw 6A is fastened by using the screw hole 51 in the attaching member 5 and the screw hole 252 in the rear cover 25 of the main body section 2  and thereby the rear surface S22 in the main body section 2 and the connection section 5A in the attaching member 5 are connected with each other. Further  the attaching screw 6B is fastened by using the screw hole 52 in the attaching member 5 and the screw hole 431 in the housing 41 of the speaker box 4  and thereby the rear surface S41 in the housing 41 of the speaker box 4 and the connection section 5A in the attaching member 5 are connected with each other. Further  the connection section 5B in the attaching member 5 is inserted into the attaching hole 421 in the housing 41 of the speaker box 4  and thereby the rear surface S41 in the housing 41 of the speaker box 4 and the connection section 5B in the attaching member 5 are connected with each other.
[0058] In the second usage aspect  as in the foregoing first usage aspect  in the display unit 1  the thickness T1 of the main body section 2 is relatively small. Therefore  the second usage aspect has a configuration suitable as wall-hanging type that is a usage aspect with a high regard for realizing a thinned display unit. Further  the sound Sout from the speaker unit 40 is outputted to the user side. Therefore  differently from the foregoing first usage aspect  the second usage aspect has a configuration with a high regard for sound and design (achieving balance between the sound and the design).
[Third Usage Aspect]
[0059] Meanwhile  in a third usage aspect illustrated in FIGs. 8A and 8B  the speaker box 4 is attached to the rear surface S22 of the main body section 2 so that the rear surface S22 of the main body section 2 is contacted with the upper surface S43 of the housing 41  and the sound Sout is outputted in the lower direction. At this time  more specifically  the attaching screw 6A is fastened by using the screw hole 51 in the attaching member 5 and the screw hole 251 in the rear cover 25 of the main body section 2  and thereby the rear surface S22 in the main body section 2 and the connection section 5A in the attaching member 5 are connected with each other. Further  the attaching screw 6B is fastened by using the screw hole 53 in the attaching member 5 and the attaching hole 421 in the housing 41 of the speaker box 4  and thereby the rear surface S41 in the housing 41 of the speaker box 4 and the connection section 5B in the attaching member 5 are connected with each other.
[0060] In the third usage aspect  differently from the foregoing first usage aspect and the foregoing second usage aspect  in the display unit 1  the width W1 of the frame region is relatively small. Therefore  the third usage aspect has a configuration suitable as stationary type that is a usage aspect with a high regard for realizing a narrowed frame. Further  as in the first usage aspect  the sound Sout from the speaker unit 40 is outputted in the lower direction (the sound Sout is not outputted to the user side). Therefore  the third usage aspect has a configuration with a high regard for design more than sound.
[0061] As described above  in this embodiment  the speaker box 4 is selectively attachable with respect to one of the lower surface S23 and the rear surface S22 in the main body section 2. In addition  the attaching member 5 is commonly used for both at the time of attachment to the lower surface S23 and at the time of attachment to the rear surface S22. Therefore  while variety of aspects of attaching the speaker box 4 to the main body section 2 is realized  a member (attaching member) unnecessary at the time of the respective attachment works is allowed to be omitted. Therefore  while usability of a user is improved  cost of members is allowed to be decreased.
