  Features:

  - Buzzer is an electronic sounder with integration structure.

  - Using DC power, it is widely used on computers, printers, photocopiers, alarm, electronic toys, automotive electronic equipment, telephone, timer and other electronic products.

  - Piezoelectric buzzer is mainly made up by multivibrator, piezoelectric buzzer chip, impedance matching unit, resonator and shell.

  - Multivibrator is composed of transistors or integrated circuits. When switched on, multivibrator vibrates and outputs o signal.

  - Impedance matcher drives piezoelectric buzzer sound.

  - Connected to rated power and the buzzer will sound continuously.

  - Can be controlled conveniently.

  Active buzzers are called active because they only need a DC voltage to produce sound. Passive buzzers need an AC voltage to produce sound.
