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.
