FT-12T-9.2A1
  • FT-12T-9.2A1
  • FBelec Piezoelectric ceramic sheet, commonly known as piezo buzzer element or piezo diaphragm

    Piezoelectric ceramic sheet is an electronic pronunciation element. Piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When AC audio signal is connected on the two electrodes, the piezoelectric sheet 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.
