The composition principle of buzzer and positive and negative orientation identification


Beep film is also called piezoelectric ceramic beep film, is one of the most widely used piezoelectric ceramics.

Buzzer is the main component of the piezoelectric buzzer. The buzzer is made of lead zirconate titanate or lead magnesium niobate piezo ceramic material. Placed on both sides of the ceramic silver electrode, the polarization and aging treatment, and then with brass or stainless steel sheet stick together.


Buzzer is the use of the principle of piezoelectric effect of work, when applied to its alternating voltage when it will produce mechanical vibration;

Conversely, it also generates a voltage signal when it exerts a mechanical force on it.

Therefore, the piezoelectric ceramic buzzer can be used as a vibration sensor.

Piezoelectric ceramic buzzer when the mechanical force generated by the voltage signal is very weak, the general use of vibration sensors should be connected to the voltage amplifier.
