In the present embodiment, the diaphragm 42 is a thin plate that is rectangular and has a width extending in the left-right direction and a height extending in the up-down direction. This height is the same as the height of the display panel 1202. Is formed.
In the present embodiment, the diaphragm 42 is made of a transparent material, for example, a synthetic resin material.

FIG. 9A is a perspective view showing a structure for attaching the exciter 44 to the diaphragm 42, and FIG. 9B is an enlarged view of FIG.
The exciter 44 is provided near one end portion in the width direction of the diaphragm 42 and extends linearly from one end portion of the diaphragm 42 toward the middle portion in the width direction.
The exciter 44 generates sound from the diaphragm 42 in the thickness direction by vibrating the diaphragm 42 based on the audio signal supplied from the audio signal processing circuit 7008.

As shown in FIGS. 6 and 7, a bracket 46 protrudes from a frame 1204 located on the back surface of the display panel 1202, and the speaker 40 is supported by the bracket 46.
As shown in FIG. 7, the bracket 46 includes a base portion 4602 that protrudes rearward from the frame 1204, and a strip-shaped support piece 4604 that is bent from the tip of the base portion 4602 and extends along the width direction of the display panel 1202. As shown in FIG. 7 and FIG. 9B, the diaphragm 42 has a screw hole of the support piece 4604 in which the screw 4612 is inserted through the screw insertion hole provided in the diaphragm 42 via the washer 4610. Are attached to the support piece 4604 by being screwed together.
As shown in FIG. 6, a cover 4410 that protects the exciter 44 is detachably attached to the exciter 44.

FIG. 10 is a front view of the display device 12 and the speaker 40.
As shown in FIG. 10, the two speakers 40 are respectively arranged on the left and right sides of the display panel 1202 at locations separated from the rear of the display panel 1202.
When the display panel 1202 is viewed from the front of the display panel 1202, each speaker 40 has a position near one end of the vibration plate 42 provided with the exciter 44 within the outline of the display panel 1202. The other end of both ends in the width direction of the display panel 1202 is disposed so as to protrude outside the outline of the display panel 1202.
As shown in FIG. 7, the vibration plate 42 is provided to be inclined with respect to the display panel 1202 so that the other end portion is located in front of one end portion where the exciter 44 is provided.
In addition, when the display panel 1202 is viewed from the front of the display panel 1202, each speaker 40 is configured such that the upper and lower edges of the diaphragm 42 are the same in the vertical direction with respect to the upper and lower edges of the display panel 1202. Has been placed.

According to the television device 10 of the present embodiment, since the display panel 1202 is disposed on the left and right sides of the display panel 1202 at a position separated from each other, a different taste from the conventional case arises, and a new design and a new A television device 10 having an aesthetic appearance is obtained, which is advantageous in increasing the purchasing power of the television device 10.
In addition, since the location near one end of the vibration plate 42 provided with the exciter 44 is located within the outline of the display panel 1202, the attachment location of the exciter 44 and the vibration plate 42 is located in front of the display panel 1202. It is hidden from the user and is advantageous in enhancing design and aesthetics.
In addition, the vibration plate 42 is provided to be inclined with respect to the display panel 1202 so that the other end portion is located forward of one end portion of the vibration plate 42 provided with the exciter 44. The sound generated forward from the portion of the plate 42 located within the outline of the display panel 1202 is reflected obliquely when hitting the frame 1204 on the back side of the display panel 1202, and between the two diaphragms 42. Exit backward from the gap. Therefore, unlike the case where the diaphragm 42 and the frame 1204 are arranged in parallel, the acoustic waves resonate between the diaphragm 42 and the frame 1204 and a standing wave component is generated. The standing wave component is not transmitted to the front of the display panel 1202.
Therefore, the sound generated from the portion of the diaphragm 42 that protrudes out of the outline of the display panel 1202 to the front can be emitted to the front of the display panel 1202 as a clear sound without being adversely affected by the standing wave component. Therefore, it is advantageous in obtaining clear sound quality.

Further, since the vibration plate 42 is provided to be inclined with respect to the display panel 1202 so that the other end portion is located in front of one end portion of the vibration plate 42 provided with the exciter 44, the left and right The sound generated from the diaphragm 42 reaches the head (both ears) of the user located in front of the display panel 1202 more effectively, and the sound image localization by the sound emitted from the speaker 40 is localized. It is advantageous in improving the feeling.
In addition, when the display panel 1202 is viewed from the front of the display panel 1202, each speaker 40 is configured such that the upper and lower edges of the diaphragm 42 are the same in the vertical direction with respect to the upper and lower edges of the display panel 1202. Since they are arranged, the display panel 1202 and the left and right speakers 40 are unified in design, which is advantageous in improving the aesthetic appearance.
Further, in this embodiment, since the diaphragm 42 is formed of a transparent material, the portion of the diaphragm 42 that protrudes outside the outline of the display panel 1202 is transparent, and thus the presence of the speaker 40 can be felt. However, it is possible to add a taste different from the conventional one to the television device 10, which is advantageous in increasing the purchasing power of the television device 10.

Note that the speaker 40 may be supported by the tip of an arm protruding from the base 22, or may be supported by an arm protruding from the support column 24 or the arm 26, as in the embodiment. Supporting with a bracket provided on the back surface of the display panel 1202 is advantageous in reducing the size of the television device 10 and in providing a floating feeling to the display panel 1202 and the speaker 40.
Further, the television device 10 in which the display panel 1202 is supported by the stand 20 has been described. However, the present invention can be applied to a television device that is directly placed on a floor or a desk without the stand 20. When the display panel 1202 is applied to the television apparatus 10 that is supported by the stand 20 as described above, it is advantageous in giving a floating feeling to the display panel 1202 and the speaker 40.
The diaphragm 42 may be formed using a colored material. However, if the diaphragm 42 is formed of a transparent material as in the embodiment, it is advantageous in providing a floating feeling to the display panel 1202 and the speaker 40. It becomes.

Further, in the present embodiment, the case where the two speakers 40 are respectively arranged on the left and right sides of the display panel 1202 at positions separated from the rear of the display panel 1202 has been described, but FIG. ), The two speakers 40 may be arranged on the upper portion of the display panel 1202 at a position separated from the rear of the display panel 1202, or in the front view of FIG. ), The two speakers 40 may be arranged at the lower part of the display panel 1202 at a position separated from the rear of the display panel 1202.
Also in this case, as in the above embodiment, each speaker 40 has one end in the height direction of the diaphragm 42 provided with the exciter 44 when the display panel 1202 is viewed from the front of the display panel 1202. The portion near the portion is located within the outline of the display panel 1202, the other end in the height direction of the diaphragm 42 is disposed so as to protrude outside the outline of the display panel 1202, and the diaphragm 42 It is provided so as to be inclined with respect to the display panel 1202 so that the other end portion in the width direction is located in front of the end portion in the width direction located near the center of 1202.
Even in such an embodiment, the same effects as in the above embodiment can be obtained.
