As shown in Figures 1 and 2, the utility model provides a piezoelectric module 100, which includes a housing 2 with a housing space 1, a piezoelectric vibration device that is accommodated and fixed in the housing 2 and has a vibrating part 30. piece 3, and one end is fixed to the vibrating part 30 and the other end extends out of the housing 2 so as to abut against the extension body 4 of the screen. The extension body 4 may directly abut and contact the screen, or may Other components are arranged between the extension body 4 and the screen to realize indirect contact, but all these belong to the protection scope of the present invention. In order to enable the piezoelectric vibrating piece 3 to be conveniently fixed in the housing 2, the piezoelectric module 100 is further provided with a support body 5 accommodated in the accommodation space 1, and the piezoelectric vibrating piece 3 It is fixed on the support body 5 , so that the piezoelectric vibrating piece 3 can keep a certain distance from the bottom wall of the housing 2 , and reserve enough vibration space for the vibrating part 30 .

The piezoelectric module 100 is used to drive the screen to vibrate or receive vibration feedback from the screen, that is, when the piezoelectric module 100 receives a driving signal from an external circuit, the vibrating part 30 of the piezoelectric vibrating piece 3 vibrates, and The extension body 4 is fixed to the vibrating part 30 and abuts against the screen. Therefore, the piezoelectric module 100 will push the screen to vibrate together. Similarly, when it is necessary to receive vibration feedback from the screen, the vibration of the screen will push The vibrating part 30 of the piezoelectric vibrating piece 3 vibrates together. Due to the inverse piezoelectric effect, the vibration feedback of the screen will be converted into an electrical signal by the piezoelectric vibrating piece 3 and output to an external circuit.
