Description

  The present invention relates to a display device used by being attached to a wall, for example, a wall-mounted television receiver (hereinafter referred to as “wall-mounted television”).

  In recent years, with the development of liquid crystal display technology, peripheral circuit technology, and the like, television receivers and the like can be manufactured to be thin and light, so that it has become possible to attach a television to a wall. When mounting a TV on a wall, it is common to mount a mounting bracket on the wall and then mount it on the wall in combination with a mounting bracket mounted on the TV body. 12 and 13 are diagrams illustrating an example of a mounting structure using a wall mounting bracket. An attachment fitting 303 attached to the wall surface W and the television 300 are attached by an attachment member 305 and a fixture 307 such as a screw.

  When mounting the TV on the wall, it is common to use such a structure because it can improve the appearance from the front by attaching the mounting bracket to the back of the TV. However, the TV is separated from the wall by the thickness of the mounting bracket, and the merit of making the TV thinner is less likely to appear.

In addition, the vibration generated in the TV speaker vibrates the TV main body, but if a loud sound is produced from the speaker, the TV vibrates greatly, which adversely affects image quality and sound quality. The vibration may cause deterioration of the liquid crystal panel. In particular, when an array speaker having a plurality of speaker units is used, the total mass of the diaphragm is large, and the vibration transmitted to the television body tends to be large.
Therefore, for example, as described in Patent Document 1 below, an elastic material is generally inserted into a vibrating portion in order to avoid the adverse effects of vibration.

JP 2001-309277 A

However, like patent document 1, when an elastic material is used for a vibration part, there exists a problem that the part supported by an elastic material will become easy to vibrate.
For example, when the speaker box is attached to the chassis via an elastic material, the speaker box that vibrates due to the reaction of vibrating the speaker diaphragm becomes easier to vibrate compared to the case where no elastic material is used. There is a problem that radiation characteristics are inferior. In addition, there is a problem that the cost increases when an elastic material is attached so that the vibration is not sufficiently transmitted to the television.
An object of the present invention is to suppress the thickness when a television is attached to a wall, to make it difficult to transmit vibrations of the speaker to the television, and to firmly attach the speaker to the wall to improve sound quality.

  According to one aspect of the present invention, there is provided a display device having a display unit, which extends from an outer edge in the vicinity of the back surface of the display device, has an engagement hole, passes through the engagement hole, and is fixed to a wall. There is provided a mounting tab for fixing the display device to the wall by a mounting screw, and a structure in which a speaker portion having a receiving portion for receiving the mounting tab is fixed by engagement of the mounting tab and the receiving portion. A display device is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the thickness at the time of attaching a display apparatus to a wall can be suppressed. Further, it becomes difficult to transmit the vibration of the speaker to the display device, and the influence on the image can be reduced. Furthermore, the speaker can be firmly attached to the wall, and the sound quality can be improved.

  Hereinafter, a display device according to an embodiment of the present invention will be described using a wall-mounted television as an example.

(First embodiment)
1 to 6 are views showing the structure of the wall-mounted television according to the present embodiment, FIG. 1 is a front view, FIG. 2 is a side view, FIG. 3 is an exploded perspective view, and FIG. FIG. 5 is a side view after attachment, and FIG. 5 is a front view after attachment. FIG. 6 is a detailed view of the attachment mechanism.

  The television 1 having the liquid crystal panel unit 201 having a display surface in the display unit 2 is provided with, for example, iron mounting tabs 202a and 202b above and below the television body. The television 1 can be directly attached to the wall by screwing the attachment tab to the wall with the screw 203. For example, the speaker portions 3a and 3b can be attached to the attachment tabs 202a and 202b, and the speaker portions 3a and 3b are attached so as to cover the attachment tabs 202a and 202b. The attachment tabs 202a and 202b are covered with the speaker portions 3a and 3b after the attachment. The speaker units 3a and 3b may be provided with speaker units to form a speaker array in which a plurality of speaker units are arranged. FIG. 2 is a schematic view of a television section viewed from the side. As shown in FIGS. 2 to 4, a fitting mechanism is attached to the mounting tabs 202a and 202b as a speaker mounting base, and the speaker portions 3a and 3b are fitted and fixed to the fitting mechanism. The fitting mechanism is fixed as shown in FIG. 4 by speaker portions 3a and 3b having a thickness substantially corresponding to the difference in thickness in the normal direction of the display surface between the mounting tabs 202a and 202b and the TV main body. . Here, the speaker portions 3a and 3b are substantially flush with the surface of the television by mounting the speaker portions 3a and 3b. A liquid crystal panel will be described as an example of a television display means, but the display means is not limited to a liquid crystal panel, and it is needless to say that the present invention can be applied to any display means such as a plasma display panel and an organic EL panel.

  As shown in FIG. 6, the fitting mechanism is provided with a gasket 204 on the mounting tab 202 in order to reduce rattling of the speaker unit 3 (3a, 3b), and the speaker unit 3 (3a, 3b). And the mechanical coupling of the mounting tab 202 is strengthened. The gasket 204 may be composed of a rubber O-ring or the like. That is, the mounting tab 202 (202a / 202b) has an engagement hole extending in a direction extending from the outer edge of the display device, and fixes the display device to the wall by the mounting screw 203 that passes through the engagement hole and is fixed to the wall. Is provided. And the speaker part 3 (3a * 3b) is fixed by the accommodating part which accommodates the attachment tab 202 (202a * 202b).

  Since the speaker unit 3 (3a and 3b) is fitted into the mounting tab 202 (202a and 202b), vibration generated in the speaker unit 3 (3a and 3b) is directly received by the wall, and vibration transmitted to the TV main body is reduced. Is done.

  More specifically, in the method in which the mass added to the speaker box is fixed to the chassis via the elastic material, the mass added to the speaker box is very small. When attached to a mounting tab attached to the wall surface, the maximum mass is the wall mass, which is sufficiently large against the reaction of the driving force that drives the diaphragm of the speaker, and heavier by the mass of the wall. Therefore, a reproduced sound with less distortion can be obtained.

The liquid crystal panel unit 201 is attached to the attachment tabs 202 (202a and 202b) by the liquid crystal panel attachment screws 205 via the elastic bushes (elastic material) 206. The elastic material 206 weakens the mechanical coupling between the mounting tabs 202 (202a and 202b) and the liquid crystal panel unit 201, and makes it difficult for vibration generated in the speaker unit 3 (3a and 3b) to be transmitted to the liquid crystal panel unit 201. Accordingly, it is possible to prevent the liquid crystal panel unit 201, the backlight, the circuit board, and the like from being squeezed and abnormal noise due to vibration of the speaker unit 3 (3a, 3b), and to prevent deterioration of the liquid crystal due to vibration.
Therefore, the strength of the wall surface is not sufficient, and even if the wall surface vibrates due to sound pressure or the like, it is possible to reduce the possibility that the liquid crystal panel unit 201 is defective.

  The same effect can be obtained even if the speaker unit 3 (3a, 3b) is fitted to the screw 203 provided with a fitting mechanism instead of the mounting tab 202 (202a, 202b). In the above example, the speaker unit 3 (3a, 3b) is fitted into the mounting tab 202 (202a, 202b), but is further fixed to the mounting tab 202 (202a, 202b) with a fixing screw or the like. good.

Although the mounting tabs 202 (202a and 202b) are mounted on the upper and lower sides, it is not necessary to mount the speaker unit 3 (3a and 3b) on the upper and lower sides, and either one may be used. Moreover, you may attach the decorative cover to which the speaker is not attached. The attachment tab may be individually attached to the liquid crystal panel unit 201 for each of a plurality of attachment points, or may be a chassis-like attachment tab having a plurality of attachment points. In the drawing, two mounting tabs 202 (202a and 202b) are provided per side, but the number is not limited to two and may be fixed at any number of points per side. At this time, as shown in FIG. 7, the position on the center of gravity above the display unit on the vertical line parallel to the display surface of the display unit 2 including the liquid crystal panel 201 and the mounting tabs 202a and 202b, that is, the center of gravity P _The mounting tab 202c may be installed directly above ₁ . By doing so, the mounting tab 202c directly above the center of gravity is temporarily fixed at one point so that the weight of the display unit 2 is balanced, and in that state, the TV is fixed to the wall. A TV can be installed horizontally without using tools. The speaker unit 3 (3a, 3b) is installed after the liquid crystal panel unit 201 is fixed.

As described above, according to the present embodiment, the mounting tab for mounting the display device to the wall is provided around the display device, and the speaker unit is attached to the mounting tab. The thickness when attached to the wall can be suppressed.
Further, by attaching the liquid crystal panel via the elastic member, it becomes difficult to transmit the vibration of the speaker to the display screen, and the influence on the image can be reduced.
