According to at least one aspect of the present disclosure, the present disclosure can match magnitudes of sounds output from a plurality of speakers.

First claim

What is claimed is:

1. A display device comprising:
a display panel;
a plate positioned in a rear of the display panel, the plate including a first part to which the display panel is fixed, and a second part extended from a lower end of the first part and bent toward a front of the first part;
a housing positioned in a rear of the second part and coupled to the second part;
a first speaker unit including a first space and a second space isolated from the first space and communicating with an outside, the first speaker unit including a first opening communicating the first space with the second space and a second opening spaced from the first opening and communicating the first space with the second space, the first speaker unit being spaced from the display panel;
a first speaker installed in the first opening and providing a sound to the second space;
a first diaphragm installed in the second opening;
a second speaker unit including a third space and a fourth space isolated from the third space and communicating with the outside, the second speaker unit including a third opening communicating the third space with the fourth space and a fourth opening spaced from the third opening and communicating the third space with the fourth space, the second speaker unit being spaced from the display panel;
a second speaker installed in the third opening and providing a sound to the fourth space; and
a second diaphragm installed in the fourth opening and having an area different from an area of the first diaphragm,
wherein the first speaker unit and the second speaker unit are installed inside the housing.

2. The display device of claim 1 , wherein the first space is larger than the third space.

3. The display device of claim 2 , wherein the area of the first diaphragm is larger than the area of the second diaphragm.

4. The display device of claim 1 , wherein the first speaker unit includes a fifth opening communicating the second space with the outside, and
wherein the first speaker is positioned closer to the fifth opening than the first diaphragm.

5. The display device of claim 4 , wherein the second speaker unit includes a sixth opening communicating the fourth space with the outside, and
wherein the second speaker is positioned closer to the sixth opening than the second diaphragm.

6. The display device of claim 4 , wherein the first opening is larger than the fifth opening.

7. The display device of claim 1 , wherein the first speaker unit includes a fifth opening communicating the second space with the outside,
wherein the display panel includes a front surface displaying an image, and
wherein the fifth opening is positioned forward.

8. The display device of claim 1 , wherein the first part is integrally formed with the second part and includes a light transmitting material.

9. The display device of claim 1 , wherein the first opening faces upward.

10. The display device of claim 1 , wherein the second opening faces upward.

11. The display device of claim 1 , wherein the first diaphragm has a quadrilateral shape.

12. The display device of claim 1 , further comprising a cover coupled to an upper side of the first speaker unit,
wherein the cover is opposite to the first speaker and the first diaphragm.
