Abstract

An electro-optical device includes an electro-optical panel, a holding frame that holds the electro-optical panel, and a sound-production frame that is attached to the holding frame, constitutes a sound-production air space at the rear of the holding frame, and holds a sound-production unit. The holding frame is provided with an internal sound-guiding path that is connected to the inside of the sound-production air space and opens to the outside.

Claims

1. An electro-optical device comprising:

an electro-optical panel;

a sound-production unit;

a sound-production frame that holds the sound-production unit; and

a holding frame that holds the electro-optical panel and that is connected to the sound-production frame, the holding frame having a rear surface wall disposed at a rear of the electro-optical panel, the rear surface of the holding frame defining a sound-production air space with the sound-production frame, the holding frame including an internal sound-guiding path that is in fluid communication with the sound-production air space and that opens to outside of the holding frame.

2. The electro-optical device according to claim 1, wherein the internal sound-guiding path opens at a front surface or a side surface of the holding frame.

3. The electro-optical device according to claim 1, further comprising a support member that is interposed between the holding frame and the sound-production frame and that defines the sound-production air space with the holding frame and the sound-production frame.

4. The electro-optical device according to claim 3, wherein an air space between the holding frame and the sound-production unit and an air space between the sound-production frame and the sound-production unit are separated from each other by the support member and the sound-production unit.

5. The electro-optical device according to claim 1, wherein the sound-production unit overlaps the electro-optical panel in plan view.

6. The electro-optical device according to claim 1, wherein the internal sound-guiding path opens at a position where the sound-production unit and the electro-optical panel do not overlap each other.

7. An electronic apparatus comprising:

the electro-optical device according to claim 1;

and

a support body that supports the electro-optical device.

8. The electronic apparatus according to claim 7, wherein an external sound-guiding path is provided between the electro-optical device and the support body so as to be connected to the internal sound-guiding path, and the external sound-guiding path opens at a surface near the electro-optical panel.

9. The electronic apparatus according to claim 8, wherein the external sound-guiding path is constituted by a sound-guiding member that is disposed between the electro-optical device and the support body.
