Abstract:
1. A touch device, comprising: a touch sensing unit; a vibrator for generating vibration; and a vibration transmitting unit installed on a backside of the touch sensing unit and connected with the vibrator for transmitting the vibration to the touch sensing unit, wherein the vibration transmitting unit comprises a vibration-homogenizing plate, and the rigidity of the vibration-homogenizing plate decreases as the distance from the vibrator increases; wherein the vibration-homogenizing plate is a metallic backside cover with plural machined structures, the metallic backside cover has a first zone close to the vibrator and a second zone distant from the vibrator, the distribution density of the machined structures in the first zone is lower than the distribution density of the machined structures in the second zone.
