Abstract

A speaker includes a hollow glass substrate and a plurality of vibration exciters. The glass substrate defines a hermetical receiving cavity. The vibration exciters are received in the receiving cavity, and are attached to the glass substrate to drive the glass substrate to vibrate, thus generating sound waves. The disclosure further relates a display having the speaker.

First claim

What is claimed is:

1. A display comprising:
a display panel; and
a speaker positioned on the display panel, the speaker comprising:
a hollow glass housing defining a hermetical receiving cavity; and
a plurality of vibration exciters received in the receiving cavity, and being attached to the glass housing to drive the glass housing to vibrate, and thus generating sound waves;

wherein the glass housing is cuboid, the glass housing defines a receiving recess receiving the display panel therein, the display panel has a display surface, the display surface is exposed from the receiving recess, the glass housing has a front wall, a back wall, an inner wall, and an outer wall, the front wall is adjacent to the display surface, the back wall is opposite to the front wall, and is away from the display surface, the inner wall is exposed in the receiving recess and is in contact with the display panel, the outer wall is opposite to the inner wall, and is away from the display surface, the outer wall is connected to the front wall and the back wall, the vibration exciters are positioned on the inner surface of the outer wall or the inner surface of the back wall, the inner surface of the outer wall and the inner surface of the back wall are exposed in the receiving cavity, the inner surface of the outer wall is connected to the inner surface of the back wall.

2. A display comprising:
a display panel; and
a speaker positioned on the display panel, the speaker comprising:
a hollow glass housing defining a hermetical receiving cavity; and
a plurality of vibration exciters received in the receiving cavity, and being attached to the glass housing to drive the glass housing to vibrate, and thus generating sound waves;

wherein the display panel has a display surface and a back surface opposite to the display surface, the glass housing is attached to the back surface, the glass housing has a front wall, a back wall, and at least one sidewall, the front wall is in contact with the display panel, the back wall is opposite to the front wall, the at least one sidewall is connected to the front wall and the back wall, the vibration exciters are positioned on an inner surface of the back wall or an inner surface of the at least one sidewall, the inner surface of the back wall and the inner surface of the at least one sidewall are exposed in the receiving cavity, and the inner surface of the back wall is connected to the inner surface of the at least one sidewall.
