Sony patents screens that make sound by vibrating the glass

Patent drawing from the official filing.

Sony describes a display system where a small device attached to the back of a screen shakes it to create sound. The system adjusts the shaking speed based on the screen's properties to produce audio without traditional speakers.

Why it mattersThis could lead to thinner TVs or monitors that do not need bulky speaker boxes, though the sound quality and volume are not specified in the filing.

In the filing’s own words

A display apparatus includes a display unit including a liquid crystal panel, an exciter that is bonded to an opposite side of a surface of the liquid crystal panel and is driven to vibrate the liquid crystal panel, and an output control unit configured to control driving the exciter in a range exceeding a predetermined frequency based on information regarding the liquid crystal panel to output sound from the liquid crystal panel.

What exactly they claim (claim 1)

1. A display apparatus comprising: a display unit including a liquid crystal panel; an exciter that is bonded to an opposite side of a surface of the liquid crystal panel and is driven to vibrate the liquid crystal panel; and an output control unit configured to control driving the exciter in a range exceeding a predetermined frequency based on information regarding the liquid crystal panel to output sound from the liquid crystal panel.
