Custom Piezoelectric Components
The piezoelectric ceramic sound-generating element, especially a lead-free piezoelectric ceramic sound-generating element, is mainly composed of metal flakes and piezoelectric ceramic flakes. The sound pressure generated by this new structure piezoelectric sounder is proportional to the number of piezoelectric ceramic sheets. By increasing the number of piezoelectric ceramic sheets, the required large sound pressure is easily achieved.
