Abstract
The present disclosure provides a piezoelectric transducer and a pressure sensing button. The piezoelectric transducer includes as follows: A piezoelectric ceramic having a shape of a sheet. An upper elastic sheet and a lower elastic sheet disposed on two opposite sides of the piezoelectric ceramic, respectively. Two ends of the upper elastic sheet are fixed to an upper surface of the piezoelectric ceramic. Two ends of the lower elastic sheet are fixed to a lower surface of the piezoelectric ceramic. A plurality of resistive layers fixed to the upper elastic sheet and the lower elastic sheet, respectively, and the plurality of resistive layers are electrically connected to each other to form a bridge structure. The piezoelectric transducer of the present disclosure can recognize the external force applied to the pressure sensing button through the resistance change and realize the pressure change detection.
