Active Speaker Buzzer Module 5V (Arduino Compatible)

Active Buzzer is an integrated structure electronic transducers, DC voltage supply, widely used in computers, printers, copiers,
alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products for sound device.

Piezo buzzer divided into electromagnetic buzzer and buzzer.
The buzzer in the circuit use the letter "H" or "HA" ( old standard with "FM", "LB", "JD" , etc.) indicates.
Buzzer mainly by multivibrator, piezo buzzer , impedance matching and resonance box , casing and other components. 
Some buzzer case is equipped with light-emitting diodes.
Multivibrator constituted by the transistors or integrated circuits . When switched on (1.5 ~ 15V DC working voltage ) , multi-harmonic oscillator start-up , the output 1.5 ~ 2.5kHZ audio signals , impedance matching push piezo buzzer sound.
Electromagnetic buzzer from the oscillator, the electromagnetic coils, magnets, and other components diaphragm and the housing
After power on, the audio signal generated by the oscillator current through the electromagnetic coil , the electromagnetic
coil generates a magnetic field . 
The electromagnetic coil and the diaphragm is the interaction of the magnet, periodically
vibrating sound.
