Buzzer piezoelectric and electromagnetic into the two categories:
Piezoelectric buzzer is the piezoelectric effect to drive the vibration of the vocal pieces of metal;
Electromagnetic buzzer, it is the principle of electromagnetic, power absorption when the metal diaphragm, the diaphragm is not under power when the elastic rebound,
Therefore, the piezoelectric buzzer is driven by a square wave, [...]
