In this way, the vibration force generated by the piezoelectric vibrator 500 driving the touch screen 200 can be transmitted in a predetermined direction, and each area on the touch screen 310 can receive a uniform and stable vibration force. In addition, the piezoelectric vibrator 500 is provided on the side wall of the housing groove 110, and the mounting space of the piezoelectric vibrator 500 in the housing groove 110 can be saved.
The piezoelectric vibrator 500 and the supporting frame 320, or the piezoelectric vibrator 500 and the touch panel 310 may abut against each other in an initial state (i.e., the touch panel 310 is in a non-vibrating state), or may be separated from each other in the initial state.
