Abstract
An input device includes a structural frame, a touch pad, a piezoelectric sheet fixed on the touch pad, and a controller electrically connected to the touch pad and the piezoelectric sheet. The touch pad has a first side, a second side opposite to the first side, and a touch-sensitive surface that has a button area located at the second side. The touch pad can be elastically deflected to move the second side relative to the structural frame. The piezoelectric sheet generates a voltage when the touch pad is elastically deflected. When determining that a press is performed on the button area and the voltage is larger than or equal to a corresponding predetermined value, the controller sends out a trigger signal. An electronic apparatus with the input device includes a display screen and a processor. The processor receives the trigger signal to control the display screen to display images.
