Abstract
A touch device includes a touch sensing unit, a vibrator and a vibration transmitting unit. The vibrator is used for generating vibration energy. The vibration transmitting unit is installed on a backside of the touch sensing unit and connected with the vibrator for transmitting the vibration energy to the touch sensing unit. The vibration transmitting unit includes a vibration-homogenizing plate. The rigidity of the vibration-homogenizing plate decreases as the distance from the vibrator increases.
