Piezo Diaphragm

Piezo Diaphragm is an electronic pronunciation element. Piezo diaphragm dielectric material is placed between two copper circular electrodes. When AC audio signal is connected on the two electrodes, the piezoelectric diaphragm will vibrate according to the size and frequency of the signal and produce corresponding sound. Because of its simple structure and low cost, piezoelectric ceramics are widely used in electronic and electrical appliances, such as toys, pronunciation electronic watches, electronic instruments, electronic clocks, timers and so on.
