Specification:

Description:
Buzzer is an electronic sounder with integration structure. Using DC power, it is widely used on computers, printers, photocopiers, alarm, telephone, timer and other electronic products.
Features:
1.Piezoelectric buzzer is mainly made up by multivibrator,piezoelectric buzzer chip, impedance matching unit, resonator and shell.
2.Multivibrator is composed of transistors or integrated circuits.When switched on, multivibrator vibrates and outputs signal.
3.Impedance matcher drives piezoelectric buzzer sound.
4.Connected to rated power and the buzzer will sound continuously.
5.Can be controlled conveniently.
