Description

  The present invention provides a housing for an electronic device having an overhang portion formed on the back surface of a front panel formed of a transparent resin material, and an attachment recess for attaching a decorative member to the surface of the front panel corresponding to the overhang portion. It relates to body structure.

  In recent years, thin display devices such as liquid crystal displays and plasma displays have attracted attention. In particular, in television receivers, there is an increasing demand for thin televisions having a large screen of about 40 inches. Since these large flat-screen televisions have a large screen, they occupy a large area in the room, and are expensive products, so various measures have been taken to match a sense of luxury and interior.

  As one of these devices, various devices using a transparent material have been proposed. For example, a thin television has been proposed that looks like a screen floating in the air when a flat display device that displays an image on a screen is visually recognized. However, since this conventional example is provided with a transparent frame around an opaque cover frame surrounding the periphery of the display screen, there is a problem that not only the apparatus becomes large but also the number of parts increases.

  On the other hand, an extremely common thin-screen television cabinet structure has a structure in which a liquid crystal display device or a plasma display device is covered with a square-shaped cover frame and a back cover. Usually, since a flat-screen television is installed so that a display screen surrounded by a square-shaped cover frame faces the front, the cover frame is most noticeable. If a transparent member can be adopted for the most prominent cover frame, it is effective to produce a high-class feeling or to match the interior of the room. In these cabinet structures, the speaker net is generally provided on an opaque frame.

  In a device such as a television receiver, it is effective to use a transparent resin material for the cover frame in order to bring out design features. However, when a transparent resin material is molded, there is a big problem that traces of extrusion pins, traces of resin injection ports, ribs, screw holes / bosses, etc. that are generated during molding are easily seen. In particular, in this type of large display device, the mold is also large, so the above problem is important. On the other hand, when the transparent resin material is used for the cover frame of the device, printing is performed from the back side, so that a sense of depth of the material can be obtained and a decoration and a high-class feeling can be produced.

  However, for molded products with a flat back surface, printing can be performed, but it is generally considered that masking coating is applied to those with a flat back surface, which requires advanced masking technology. .

  Moreover, when attaching a speaker net or a decorative member to the surface of these transparent resin materials, a concave portion for attaching a decorative member or the like is provided on the surface, and the concave portion is attached to this concave portion. In general, an overhang is formed to make the entire wall thickness uniform. However, when this structure is adopted, the overhanging portion on the back surface is formed larger than the concave portion, so that there is a problem that the border is seen through the concave portion when viewed from the front.

  Accordingly, an object of the present invention is to provide a casing structure of an electronic device in which a decorative member is provided on the surface of a transparent resin material while maintaining strength and without a sense of incongruity.

  In order to achieve the above object, a housing structure of an electronic device according to the present invention includes a protruding portion formed on the back surface of a front panel formed of a transparent resin material, and the front panel surface corresponding to the protruding portion. A mounting recess for mounting the decorative member, and the mounting recess is formed in the first mounting recess with a first mounting recess for mounting the decorative member and a member mounting surface on at least one side thereof. The decorative member is attached to the member mounting surface including the first decorative member fitted and attached to the second mounting concave portion, and the front surface of the first decorative member. And the overhanging portion is formed within the projected area of the first mounting recess.

  ADVANTAGE OF THE INVENTION According to this invention, a decorative member can be provided in the surface of a transparent resin material without a sense of incompatibility, maintaining intensity | strength.

  Hereinafter, a display device according to the present invention will be described in detail with reference to FIGS. 1 to 11 by taking a television receiver as an example. In addition, the same site | part, the same arrow, etc. attach | subject the same code | symbol, and abbreviate | omit duplicate description.

  First, the schematic structure of the television receiver according to this embodiment will be described with reference to FIG. FIG. 1 is a development view of components of a television receiver, showing a development view of components at the center, an external view at the upper left, and a partial sectional view near the speaker at the lower right.

The television receiver 1 includes a main body casing 100 including a liquid crystal monitor device 10 and a stand 200 that supports the main body casing 100 from below. The stand 200 can be attached to and detached from the main body casing 100. When the stand 200 is attached, the stand 200 can be installed on the floor surface or a television stand (not shown). The main body housing 100 can be attached to a wall surface or the like via In this embodiment, the bottom speaker type in which the speaker 30 is provided in the lower front part will be described. However, the present invention is not limited to this, and a side speaker type in which the speaker 30 is provided on both sides of the front or a monitor without the speaker 30. The main configuration can also be applied.

  The main body housing 100 is housed between the front case 101 constituting the front surface of the main body housing 100, the back case 102 constituting the rear part of the main body housing 100, and the back case 102 and the front case 101. And the liquid crystal monitor device 10.

  The front case 101 includes a front bezel 103 that is formed in a square shape so as to surround the display screen 10 a of the liquid crystal monitor device 10, and a square-shaped bezel base that connects the front bezel 103 and the back case 102. 104. In this embodiment, the front bezel 103 is formed of a transparent resin material or a translucent resin material mixed with a pigment, and the back surface is painted. The bezel base 104 is formed of a resin material and has a structure that is screwed to the back case 102 on the back surface thereof. On the other hand, the back case 102 is formed of a resin material, and holds the liquid crystal monitor device 10 between the bezel base 104.

  In this embodiment, since the liquid crystal monitor device 10 is formed by a known technique, a detailed description is omitted, but the back surface is formed by the metal plate 11 and the metal plate 11 is formed by a metal material. By providing a plurality of columns 12, the liquid crystal monitor device 10 itself is used as a main strength member. Then, by attaching the front bezel 103, the bezel base 104, and the back case 102 to the strength member, the overall strength of the main body casing 100 is maintained.

  Further, the stand 200 includes a pair of attachment members 201 at the upper portion thereof, and by inserting the attachment members 201 into the reinforcing pillars 12 and attaching them, the main body housing 100 can be supported from below. In the case of wall mounting, a mounting bracket (not shown) is mounted on the reinforcing column 12 from the back case 102 and is mounted on the wall surface via the mounting bracket.

  One of the major features of the television receiver 1 according to this embodiment is that the border formed around the speaker 30 formed on the surface of the transparent resin material is difficult to see from the surface. That is, in this embodiment, the overhang portion 42 is formed on the back surface of the front bezel (front panel) 103 formed of a transparent resin material, and the decorative member is attached to the surface of the front bezel 103 corresponding to the overhang portion 42. The mounting recess 41 is formed in the first mounting recess 41a with a first mounting recess 41a for mounting the decorative member and a member mounting surface on at least one side thereof. The decorative member includes a first decorative member (decorative member) 48 fitted and attached to the second mounting concave portion 41b, and a front surface of the first decorative member 48. Including a second decorative member (speaker net) 40 attached to the attachment surface 45 of the member, and the overhanging portion 42 is formed within the projected area of the first attachment recess 41a. Is is so.

  According to this embodiment, the overhanging portion 42 is concealed by the first mounting recess 41a into which the first decorative member (decorative member) 48 and the second decorative member (speaker net) 40 are fitted. The trace of the overhang part 42 formed around the attachment recess 41 can be made difficult to see from the surface. In addition, since the thickness of the front bezel 103 is secured by the stepped portion 43 of the first mounting recess 41a and the second mounting recess 41b, the strength is not hindered.

  The television receiver according to this embodiment will be specifically described below with reference to FIGS. Here, FIG. 2 is an external view of a television receiver. FIG. 2 (a) is a plan view, FIG. 2 (b) is a front view, FIG. 2 (c) is a right side view, and FIG. FIG. 2 (e) is a left side view and FIG. 2 (f) is a bottom view. FIG. 3 is an assembly process diagram of the main body casing. FIG. 4 is a process diagram for molding the front bezel. FIG. 5 is a masking process diagram of the front bezel. FIG. 6 is a diagram for explaining the visual action of the front bezel. FIG. 7 is a cross-sectional view showing another application example of the front bezel. FIG. 8 is a perspective view showing a partial cross section of the main body housing. FIG. 9 is an explanatory diagram showing the problem of light transmission of the transparent material. FIG. 10 is a cross-sectional view of the vicinity of the speaker unit. 11A and 11B are external views of a stand mounting member, FIG. 11A is a plan view, FIG. 11B is a front view, FIG. 11C is a side view in use, and FIG. 11D is an external view. It is a perspective view.

  First, the external shape of the television receiver 1 will be described with reference to FIG. In this embodiment, the display screen 10a of the liquid crystal monitor device 10 is exposed in a rectangular shape, and a square-shaped front bezel 103 is provided so as to surround the periphery. The front bezel 103 is formed of a translucent resin material having a color by mixing a transparent resin material or a pigment. The front bezel 103 has an inner peripheral surface 105 provided with a paint layer 109 (see FIG. 3) and an outer peripheral surface not provided with the paint layer 109 via mounting ribs 107 (see FIG. 3) provided on the rear surface thereof. The outer peripheral surface 106 is formed in a shape that protrudes like a flange on the outer periphery of the main body housing 100.

  Therefore, the observer can visually recognize the coating layer 109 through the transparent resin material around the display screen 10a and can visually recognize the background through the transparent resin material on the outer side. In particular, in this embodiment, since the case inclined surface 111 (a large curved surface) is provided with a tapered shape around the back case 102 constituting the rear portion of the main body casing 100, the observer projects in the shape of the collar. Further, since the back case 102 is viewed through the light-transmitting front bezel 103, the thinness of the main body casing 100 can be realized.

  In addition, in this embodiment, a variety of colors and patterns can be applied to the coating layer 109, and the coating layer 109 is viewed through a translucent resin material. Can be given. Further, the front bezel 103 has a shape in which the inner peripheral side is flat and the outer peripheral side is inclined, and the inner peripheral surface 105 (see FIG. 1) has a curved shape with a three-dimensional effect. You can make it.

  In this embodiment, the operation switch portion 31 and the external connector portion 32 are provided on the bottom surface portion of the main body housing 100. In the prior art, the operation switch unit 31 is generally housed in a lid provided on a lower frame of the display screen, or on a side surface or an upper surface of the main body casing 100. In addition, the external connector portion 32 is generally housed in a lid provided on the lower frame of the display screen, or provided on the side surface and further on the back surface side of the main body housing 100. In particular, in the case where the operation switch unit 31 and the external connector unit 32 are provided on the front surface of the main body housing 100, the open / close lid impairs the design or the wiring with the external device is visible. was there.

  Therefore, in this embodiment, as shown in FIG. 1, a structure is employed in which the operation board 31a and the external connector board 32a are provided between the reinforcing columns 12, respectively. Thereby, since the operation switch part 31 and the external connector part 32 are separately provided on the bottom surface of the main body casing 100, it is not necessary to provide the opening / closing lid on the front bezel 103, so that the design can be improved. In addition, operability and wiring processing are not hindered.

  Next, with reference to FIG. 4 to FIG. 8 based on FIG. 3, the case structure characterized by the transparent resin material of the television receiver 1 according to this embodiment will be further described.

  In FIG. 3, the front bezel 103 has a thin plate shape as a basic shape, and a mounting rib 107 is formed on the back side thereof so as to project rearward so as to divide the inner peripheral surface 105 and the outer peripheral surface 106. Yes. In this embodiment, the front bezel 103 has a front surface formed of a flat surface 112 on the inner peripheral side and an inclined surface 113 inclined rearward on the outer peripheral side. The mounting rib 107 is formed at the central portion of the inclined surface 113.

  On the other hand, the shape on the back side of the front bezel 103 is formed flat so that the inside of the flat surface 112 is parallel to the flat surface 112, and the portion inside the inclined surface 113 is the inclined surface of the front surface. It is formed with a curved surface 115 that greatly falls backward from 113. That is, the front bezel 103 is formed with substantially the same thickness on the inner peripheral side (display screen 10 a side), and the thickness reaching the outer peripheral surface 106 on the outer peripheral side gradually increases toward the mounting rib 107. It is formed into a shape. On the other hand, the outer side of the mounting rib 107 has a sharp shape (wedge-shaped cross section) because the outer peripheral surface 106 is formed as an upright flat surface. The front bezel 103 having this cross-sectional shape is manufactured by a molding method as shown in FIG.

  In FIG. 4, in this embodiment, the mold 300 includes a first mold 301 that forms the front side of the front bezel 103 and a second mold 302 that forms the back side of the front bezel 103. Then, resin is injected and molded from a resin injection port 303 provided at the tip of the mounting rib 107. After molding, the front bezel 103 molded through the push pin 304 provided at the tip of the mounting rib 107 is taken out from the mold 300, and the tip of the mounting rib 107 is post-processed to finish the molding.

  According to this molding method, since the resin injection port 303 and the push pin 304 are concentrated on the tip of the mounting rib 107, if the mounting rib 107 is post-processed and cut, another front Traces at the time of molding can be eliminated from the peripheral side surface of the bezel 103. In addition, since there is a possibility that sink marks may occur around the mounting rib 107, in this embodiment, the resin material is solidified while pressure is applied, and then removed from the mold 300.

  Further, as shown in FIG. 5, in this embodiment, masking coating is applied to the inner peripheral surface 105 using the coating means 500. As described above, this is because the mounting rib 107 is provided on the back surface of the front bezel 103 or the inner peripheral surface 105 has a three-dimensional shape. In performing masking coating, a jig 320 that exposes only the inner peripheral surface 105 is attached to the front bezel 103. Here, in this embodiment, the corner 110a on the outer peripheral side of the back surface 108 of the mounting rib 107 is the boundary 110 between the coating layer 109 and the portion without the coating layer 109, so that the accuracy of masking coating is improved. Yes.

  Furthermore, in this embodiment, the step groove 114 is formed in the corner 110a that becomes the boundary 110 of the masking coating, thereby facilitating the attachment of the jig 320 and further improving the accuracy of the masking coating.

  In this embodiment, the step groove 114 is provided in the corner portion 110a. However, the masking coating can be performed without providing the step groove 114 in the corner portion 110a.

  Returning to FIG. 3, the front side of the bezel base 104 is formed with an outer shape that fits the inner peripheral surface 105 of the front bezel 103, and a screw mounting portion 104a with other members is provided on the inner side. It is formed. On the other hand, a screw attachment portion 102 a that matches the screw attachment portion 104 a is also provided inside the back case 102.

  In this embodiment, the bezel base 104 is adhered to the inner peripheral surface 105 of the front bezel 103 with a double-sided tape (not shown), and then the liquid crystal monitor device 10 is attached to the inside of the bezel base 104. Furthermore, the main body housing 100 is assembled by inserting the screw attachment portion 102a and the screw attachment portion 104a from the back case 102 side through the screws 116 and fastening them.

  Thus, according to this embodiment, the liquid crystal monitor device 10 can be securely held inside the bezel base 104 and the back case 102 by screwing. Then, by adhering the front bezel 103 made of a transparent resin material provided with the coating layer 109 to the bezel base 104, it is possible to conceal the screwing trace and the trace of the bezel base 104 with the coating layer 109. Moreover, the front bezel 103 can be attached to the bezel base 104 via adhesion and attachment ribs 107.

  According to this structure, a surface layer having a three-dimensional effect and a depth sensation is formed on the outside of the display screen 10a, and a surface layer having a sense of transparency is further formed on the outside thereof, so that the design can be improved. .

  Here, in this embodiment, a structure that does not use screws when mounting the front bezel 103 is realized. However, when a dark color is applied to the coating layer 109, a dark color of the same color is applied from the outside of the mounting rib 107. The applied screw 116 a can be inserted and attached to the bezel base 104. In such a special case, the front bezel 103 and the bezel base 104 can be screwed together to firmly connect both members.

  Next, how the transparent resin material is seen will be described with reference to FIG. Here, FIG. 6A shows the main body housing 100 according to the present embodiment, FIG. 6B shows an example of a transparent resin material having the same thickness, and FIG. 6C shows FIG. ) Shows a case where the plate-shaped member is wrapped around the main body, and FIG. 6D shows a case where the plate-shaped member of FIG. 6C is provided with a difference in thickness. In all cases, the transparent surface is provided with a printed surface (including a painted surface).

  First, since the example of FIG. 6B is formed of the transparent resin material 400 having the same thickness, the observer can see the printed surface 401 on the back side and can obtain a sense of depth. A three-dimensional effect cannot be obtained on the printing surface 401 provided on the flat surface. And since there is a transparent part on the outside, the observer suddenly sees the transparent part from the sense of depth, and the part 402 that receives the feeling of depth and the part 403 that receives the feeling of transparency are clearly separated. Will receive. In addition, since the boundary 404 between the two parts is clearly observed, the accuracy of the parting line greatly affects the design.

  On the other hand, in the case of FIG. 6C, the end portion of the transparent resin material 400 is wrapped around the main body, so the observer sees the end surface 405 of this end portion. This end surface 405 is an observer's observation surface and also picks up light from the rear, so that it looks like a bright band to the observer. Therefore, in this example, it is observed that a bright edge can be seen on the outside of the portion 402 receiving the feeling of depth provided by the portion formed of the transparent resin material 400 having the same thickness. In addition, in this case, the masking painting method is adopted because the back side is bent and formed.

  Further, in the case of FIG. 6D, although the surface of the portion 402 that receives the depth sensation is formed in an arc shape, the observer sees the printed surface 401 on the back side, and thus obtains a three-dimensional effect. Not up to. Then, as in the case of FIG. 6C, a bright edge can be seen on the outer side of the portion 402 receiving the sense of depth, which is not preferable in appearance. Moreover, since the back side is also bent in this case, a masking technique is adopted.

  In the case of FIG. 6D, if a transparent transparent resin material that is colored is employed, a three-dimensional effect can be obtained due to the difference in transmittance.

  On the other hand, according to the embodiment of the present invention shown in FIG. 6A, the observer sees the three-dimensional coating layer 109 applied to the inner peripheral surface 105 that gradually moves backward from the front. As a result, there is a sense of depth and a three-dimensional shape can be visually recognized. Moreover, since the back surface 108 of the mounting rib 107 also does not pick up light from the rear, it can be recognized on the extended line of the modeling with a sense of depth and a three-dimensional effect.

  On the other hand, since a transparent layer is formed on the outside of this three-dimensional model with a sense of depth, there is a sense of depth and a soft texture between the three-dimensional model and the background of the main body casing 100 You can relax and adjust the main body housing 100 to the interior.

  Furthermore, in this embodiment, it is possible to employ a resin material having translucency obtained by coloring a transparent resin material. If this resin material having translucency is employed, the appearance of the painted surface 109 can be made invisible or easily visible by changing the thickness of the resin. Therefore, by combining the resin material having translucency and the colors and patterns of the painted surface 109, it is possible to combine a sense of depth, a three-dimensional effect, and various patterns.

  In the cases of FIGS. 6C and 6D as well, the end surface 405 is formed around the portion 402 that receives the depth sensation by providing a painted surface using the same kind of method as in this embodiment. The bright edge can be erased. Moreover, the formation of a three-dimensional effect can be provided to the observer by forming a large rounded portion around the main body.

  In FIG. 7, the front bezel 103 is not limited to the form described with reference to FIGS. For example, the same function and effect can be obtained even with other shapes as shown in FIG.

  In the embodiment shown in FIG. 7A, the front surface of the front bezel 103 is formed flat. According to this embodiment, the appearance of the front bezel 103 can provide a viewer with a deep texture while taking a flat shape.

  In the embodiment shown in FIG. 7B, the inner peripheral surface 105 is provided with an uneven pattern. In this embodiment, while providing a flat shape on the front surface, it is possible to provide a viewer with a three-dimensional texture by creating a shadow according to the viewing angle of the deep color surface (paint layer 109).

  In the embodiment shown in FIG. 7C, the front surface of the front bezel 103 is a three-dimensional shape. According to this embodiment, various textures can be provided to the observer by combining the shape that can be visually recognized on the surface and the color surface (paint layer 109) that can be seen in the back.

  In the embodiment shown in FIG. 7D, the front bezel 103 is not formed in a square shape, but is formed in a flat surface that covers the entire display screen 10a. In this case, of course, the coating layer 109 is not provided on the surface of the display screen 10a. In this way, it is possible to provide a material feeling in which the coating layer 109 that is hidden behind the main body housing 100 has a flat shape on the front surface.

  The embodiment described above is an example, and the present invention is not limited to this. By providing the shape as described above, a frame body that provides a sense of depth and stereoscopic effect is provided around the display screen 10a, and a television receiver 1 having a transparent frame that can be harmonized with the background around the display screen 10a is provided. can do. Moreover, the said effect can provide the television receiver 1 provided with the various material feeling by combining a transparent resin material and the translucent resin material provided with the color. In addition, a resin material obtained by mixing a transparent resin material or a resin material with a color to the extent that light transmittance is not impaired may be employed.

  FIG. 8 shows a perspective view with a partial cross section of the main body housing 100 as seen from the rear. As described above, according to the structure of the main body casing 100, when viewed from the front side, a casing surface having a sense of depth and a three-dimensional feeling with a deep-shaped depth around the display screen 10a is provided. Furthermore, a frame body having a transparent material feeling that fuses with the background is provided.

  And even if this structure sees the main body housing | casing 100 from a back surface, there exists an effect which improves the design property. That is, in this embodiment, since a transparent frame body (front bezel 103) projecting in a flange shape is formed around the main body casing 100, the transparent body serves as an intermediary between the opaque casing portion and the surrounding background. Thus, the main body casing 100 can be melted into the background. In addition, in this embodiment, the case inclined surface 111 is formed around the back case 102 so as to be continuous with the transparent frame body (front bezel 103) protruding in the shape of a collar. Can show.

  In addition, in this embodiment, the case inclined surface 111 is formed with a recessed portion 111b that is recessed in a stepped shape on the inner side, leaving a slanted surface 111a on the outer periphery thereof. By performing the processing, the main body housing 100 can be made thinner by forming the concave portion 111b between the hatched portion 111a and the back flat surface portion 111c. In addition, the back flat surface portion 111c inside the inclined surface portion 111a and the case inclined surface 111 is subjected to a gloss treatment, thereby improving the design of the back surface of the main body housing 100 and projecting into a brim shape formed around it. Harmony with the transparent frame (front bezel 103) is achieved. Moreover, in this embodiment, in order to improve the heat dissipation effect, the heat dissipation holes 117 are provided in the recess 111b and the back flat surface portion 111c. However, if the heat dissipation holes 117 are centrally arranged in the recess 111b, the design can be further improved. Can do.

  In addition, in this embodiment, the gloss treatment is performed on the slope portion 111a. However, the same effects as those obtained when the gloss treatment is performed can also be obtained by performing the texture processing on the slope portion 111a.

  Next, a specific structure of the speaker 30 will be described with reference to FIGS. 9 and 10. Here, FIG. 9 is an explanatory diagram of the problem of the transparent resin material, and FIGS. 9A to 9C show the right cross-sectional shape and the left front shape as a pair. FIG. 10 is a cross-sectional view of the vicinity of the speaker.

  In FIG. 9, the transparent resin material is a material that is very difficult to form because the inside can be seen through, as described above. When attaching the speaker net 40 to this transparent resin material, it is necessary to consider this problem. This will be described with reference to FIG.

  FIG. 9A shows a cross-sectional view of a state in which a very general speaker net 40 is attached to the front bezel 103. When the speaker net 40 is attached, the concave portion 41 that absorbs the thickness t1 of the speaker net 40 is formed in the front bezel 103. Since the strength of the front bezel 103 decreases when the concave portion 41 is formed, it is common to form an overhang portion 42 that is slightly larger to absorb the depth of the concave portion 41 inside the front bezel 103 as a countermeasure. In this case, the length Q1 of the overhanging portion 42 is larger than the length Q2 of the concave portion 41, and the stepped portion 43 having a refracted cross-sectional shape is formed above and below the concave portion 41 (on the drawing).

  When the observer observes the transparent resin material, there is a problem that the observer sees the modeling on the back side of the front bezel 103. When the right sectional shape of FIG. 9A is viewed from the left front view, the bent line 43a forming the stepped portion 43 formed on the back surface side of the front bezel 103 will be visible from the front side.

  If the bend line 43a is made invisible and an attempt is made to reduce the distance between the bend line 43a and the speaker net 40 as shown in FIG. 9B, the strength of the front bezel 103 becomes weak. Further, even if the stepped portion 43 is formed by the inclined surface 44 as shown in FIG. 9C, the bent line 43a is visible. Although not illustrated, similarly, even if the inclined surface 44 is processed in a large round shape, the rounded ridge line appears as light reflection.

  As described above, when the concave portion 41 for absorbing the thickness of the member such as the speaker net 40 is formed in the transparent resin material, the strength of the transparent resin material is maintained and the depth of the concave portion 41 is absorbed. Are formed on the back surface of the transparent resin material. However, there is a problem that the bent line 43a of the stepped portion 43 for forming the overhanging portion 42 is visible around the recess 41.

  Therefore, the television receiver 1 according to this embodiment is devised to make the bent line 43a formed around the speaker net 40 difficult to see. This device will be described with reference to FIG.

  In FIG. 10, in this embodiment, when the speaker net 40 constituting the front portion of the speaker 30 is attached to the front bezel 103 made of a transparent resin material, a two-step recessed portion 41 is formed on the front side of the front bezel 103. The concave portion 41 forms a first concave portion 41a having a height (length) Q2, and has a height (length) Q3 shorter than the height (length) Q2 in the first concave portion 41a. A second recess 41b having a mounting surface 45 is formed. On the other hand, on the back side of the front bezel 103, an overhang portion 42 is formed at a position corresponding to the first recess 41a. The projecting amount of the projecting portion 42 toward the back surface is a dimension obtained by adding the thickness t3 of the front bezel 103 to the depth t2 of the second recess 41b.

  That is, in this embodiment, the first concave portion 41a is formed in front of the step portion 43 formed around (at least vertically) the overhang portion 42. For this reason, the bent line 43a of the stepped portion 43 coincides with the end portion of the first recess 41a formed on the front surface thereof, so that the bent line 43a can be hardly seen from the front. On the other hand, the strength of the recess 41 can be maintained by the connection step portion 46 formed between the first recess 41a and the second recess 41b. In this embodiment, the sound emitting hole 48b is formed in the second recess 41b, and the speaker body 47 is positioned on the back side of the overhanging portion 42.

  On the other hand, in this embodiment, the member attached to the concave portion 41 includes an opaque speaker net 40 in which many fine holes are formed corresponding to the two-step concave portion 41, and a decorative member formed of a resin material. 48. In this embodiment, in order to increase the decorativeness of the speaker 30, a thin decorative line 48 a is formed along the longitudinal direction at the lower end portion of the speaker 30, and the decorative line 48 a is formed by the decorative member 48. Although the decoration member 48 has a thickness t4 of the second recess 416 at the top and a size that fits into the second recess 41b, the lower end of the decoration member 48 is the mounting surface 45 of the first recess 41a. And the fitted front part protrudes forward to form the decorative line 48a. The decorative member 48 has a sound emitting hole 48b formed at a position above the decorative line 48a. On the other hand, the speaker net 40 is attached so as to fit into the attachment surface 45 of the first recess 41a and the decoration member 48 at the upper part of the decoration line 48a.

  Thus, in this embodiment, the first recess 41a is formed on the front surface of the transparent resin material (front bezel 103), and the first recess 41a is formed in the first recess 41a leaving the mounting surface 45 around (at least vertically). A recess 41 having a two-stage structure formed by two recesses 41b is formed, and a protruding portion 42 is formed on the back surface of the resin material (front bezel 103) that corresponds to the projection area of the first recess 41a. . Then, the first member (decorative member 48) that contacts the one mounting surface 45 and fits into the second recess 41 b is attached to the two-step recessed portion 41, and the first member that contacts the other mounting surface 45 contacts the first mounting surface 45. A second member (speaker net 40) that covers the front part of one member (decorative member 48) and fits into the first recess 41a is attached.

  According to this structure, the first recess 41a can be concealed from the front by the first member (decorative member 48) and the second member (speaker net 40). In addition, since the concave portion 41 has a two-stage structure, the strength of the protruding portion 42 protruding rearward can be improved by the connection step portion 46 formed by the first concave portion 41a and the second concave portion 41b. Furthermore, the strength of the overhanging portion 42 can be further improved by bonding and fitting the first member (decorative member 48) to the second recess 41b. Similarly, the strength in the vicinity of the speaker 30 can be further improved by bonding the second member (speaker net 40) across the first member (decorative member 48) and the first recess 41a.

  In addition, if the decorative line 48a is formed of a thin linear member, there are problems in peeling and assembling. However, in this embodiment, since the function as an attachment member of the speaker net 40 is provided, the problem is solved. can do.

  11, this embodiment is substantially the same as the case of FIG. 1, except that the liquid crystal monitor device 10 of FIG. The plasma monitor device 20 includes a rectangular frame casing 21, a screen protection glass 22 attached to the front surface of the frame casing 21, a plasma panel 23 attached to the rear surface of the frame casing 21, and plasma on the frame casing 21. The reinforcing column 12 is attached so as to hold the panel 23, and the substrate 24 is attached to the reinforcing column 12.

  In this embodiment, the back case 102 and the bezel base 104 are screwed so as to hold the frame housing 21 with the frame housing 21 therebetween, and the front bezel 103 is attached to the bezel base 104 with double-sided tape or the like. Further, the stand 200 and a wall surface attachment (not shown) are attached via the reinforcing pillar 12.
