Explanation:
Detailed explanation-1: -Piezo elements have the useful property of being bidirectional; that is they can move when you apply electricity to them, but they can also generate electricity when you move them.
Detailed explanation-2: -Piezo buzzer The multi-resonator consists of transistors or integrated circuits. When the power supply is switched on (1.5 15V DC operating voltage), the multi-resonator oscillates and outputs 1.5 2.5kHz audio signal. The impedance matcher pushes the piezoelectric plate to generate sound.
