Abstract

A display apparatus includes: a display panel configured to display an image, at least one supporting member on a rear surface of the display panel, the at least one supporting member defining a groove, at least one sound generation device adjacent to the display panel, and a wiring, accommodated into the groove, configured to transfer a signal to the at least one sound generation device.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display panel configured to display an image;
at least one supporting member on a rear surface of the display panel;
at least one sound generation device on the rear surface of the display panel, the at least one sound generation device being configured to vibrate the display panel; and
a wiring configured to transfer a signal to the at least one sound generation device,
wherein the at least one supporting member comprises:
a first supporting member comprising a hole, and
a second supporting member between the display panel and the first supporting member and including a groove, and

wherein the wiring extends to a rear surface of the first supporting member through the hole.

2. The display apparatus of claim 1 , wherein the wiring extends along the groove toward the hole.

3. The display apparatus of claim 1 , wherein:
the at least one sound generation device comprises:
a first sound generation device; and
a second generation device; and

the groove is between the first sound generation device and the second generation device.

4. The display apparatus of claim 3 , wherein:
each of the first sound generation device and the second generation device comprises a terminal; and
the groove is between the terminal of the first sound generation device and the terminal of the second generation device.

5. The display apparatus of claim 1 , wherein the at least one sound generation device is a circular shape or an oval shape.

6. The display apparatus of claim 5 , wherein:
the at least one sound generation device comprises a bobbin configured to the display panel; and
the bobbin is a circular shape or an oval shape.

7. The display apparatus of claim 1 , wherein:
a rear cover is on the rear surface of the first supporting member; and
the wiring extending to the rear surface of the first supporting member is covered by the rear cover.

8. The display apparatus of claim 7 , wherein:
a rigid bar and a rear cover are on the rear surface of the first supporting member; and
the rigid bar and the wiring extending to the rear surface of the first supporting member are covered by the rear cover.

9. The display apparatus of claim 7 , wherein:
a driving circuit unit configured to transfer the signal to the wiring is on a rear surface of the first supporting member; and
the wiring is electrically connected to the driving circuit unit.

10. The display apparatus of claim 9 , wherein:
a rear cover is on the rear surface of the first supporting member; and
the driving circuit unit is covered by the rear cover.

11. The display apparatus of claim 1 , wherein the at least one sound generation device is configured to vibrate the display panel to generate:
sound having a middle-high-pitched sound band; and
sound having a low-pitched sound band.

12. The display apparatus of claim 1 , further comprising a partition on the rear surface of the display panel and in a periphery of the display panel.

13. The display apparatus of claim 12 , wherein the wiring pass through between the at least one supporting member and the partition.

14. The display apparatus of claim 1 , further comprising:
a partition on the rear surface of the display panel and in a periphery of the display panel,
wherein the wiring pass through between the first supporting member and the partition.

15. A display apparatus, comprising:
a display panel configured to display an image, the display panel comprising:
a first region;
a second region; and
a third region;

at least one supporting member on a rear surface of the display panel;
at least one sound generation device configured to vibrate the display panel to generate sound, the at least one sound generation device being in at least one of: the first region, the second region, and the third region; and
a wiring between the display panel and the at least one supporting member, the wiring being configured to transfer a signal to the at least one sound generation device,
wherein the at least one supporting member comprises:
a first supporting member comprising a hole, and
a second supporting member between the display panel and the first supporting member and including a groove, and

wherein the wiring extends to a rear surface of the first supporting member through the hole.

16. The display apparatus of claim 15 , wherein the wiring extends along the groove toward the hole.

17. The display apparatus of claim 15 , wherein:
the at least one sound generation device comprises:
a first sound generation device; and
a second generation device; and

the groove is between the first sound generation device and the second generation device.

18. The display apparatus of claim 17 , wherein:
each of the first sound generation device and the second generation device comprises a terminal; and
the groove is between the terminal of the first sound generation device and the terminal of the second generation device.

19. The display apparatus of claim 15 , wherein the at least one sound generation device is a circular shape or an oval shape.

20. The display apparatus of claim 19 , wherein:
the at least one sound generation device comprises a bobbin configured to the display panel; and
the bobbin is a circular shape or an oval shape.

21. The display apparatus of claim 15 , wherein:
a rear cover is on the rear surface of the first supporting member; and
the wiring extending to the rear surface of the first supporting member is covered by the rear cover.

22. The display apparatus of claim 15 , wherein:
a driving circuit unit configured to transfer the signal to the wiring is on a rear surface of the first supporting member; and
the wiring is connected to the driving circuit unit.

23. The display apparatus of claim 22 , wherein:
a rear cover is on the rear surface of the first supporting member; and
the wiring connected to the driving circuit unit is covered by the rear cover.

24. The display apparatus of claim 15 , wherein:
a rigid bar is on a rear surface the first supporting member; and
the wiring is under the rigid bar.

25. The display apparatus of claim 15 , wherein:
the first region is a left region of the display panel;
the second region is a right region of the display panel; and
the third region is a center region of the display panel.

26. The display apparatus of claim 15 , wherein:
sound having a middle-high-pitched sound band is generated in each of the first region and the second region; and
sound having a low-pitched sound band is generated in the third region.

27. The display apparatus of claim 15 , further comprising:
