Piezo Disk

Product Detail

Piezo Disk Customized

We can custom various piezo disk according to your requirement.




Piezo Disk working principle

The source of the piezoelectric buzzer sound element comes mainly from the piezoelectric diaphragm. The piezoelectric diaphragm consists of a piezoelectric ceramic plate printed with electrodes on both sides and a metal plate (brass or stainless steel, etc.). The use of adhesives, the piezoelectric diaphragm, and metal bonding together, this is what we commonly knew as the buzzer.
