buzzer is the use of piezoelectric effect principle, when applied to the alternating voltage it will generate mechanical vibration; conversely, the applied mechanical force it will produce a voltage signal. Therefore, it can be used as a vibration sensor using the piezoelectric ceramic buzzer. The voltage signal generated by the mechanical force is very weak, and the vibration sensor is used to connect the voltage amplifier.

pressure electric ceramic buzzer buzzer consists of a piezoelectric ceramic plate and the metal diaphragm adhesive composition, metal diaphragm material is brass, iron, stainless steel, nickel alloy, usually pressure electric ceramic buzzer buzzer round. It is mainly divided into excitation type, self-excited etc.

main features: good sound quality, thin and light, low power consumption, long service life. The main technical indexes of
: resonant frequency, resonant impedance, static capacitance.

main application: watches, toys, camera, telephone, electronic music toy card, electronic door bell, household appliances, reversing device, alarm and detection and automatic control system.
