When an alternating voltage is applied to the piezo buzzer, it generates mechanical deformation, expanding and contracting due to the piezoelectric effect. This deformation causes the metal plate to vibrate and produce sound.
The so-called "piezoelectric effect" refers to the phenomenon where the piezo element deforms when a voltage is applied. This is also known as the inverse piezoelectric effect.
Micro speaker composed of Magnet, Voice Coil, and Diaphragm
When electric current passes through the coil, it generates a magnetic field, which moves the diaphragm and pushes the surrounding air to vibrate, thereby producing sound.
The working principle is based on energy conversion, where electrical energy is first converted into magnetic energy, then magnetic energy is converted into mechanical energy, and finally, mechanical energy is converted into sound.
Due to its various applications, it has different names: speaker, receiver, transmitter, amplifier, etc.
It is used in devices such as telephones, mobile phones, earphones, alarms, and any equipment requiring sound.
Acoustic Component – Electret Condenser Microphone
The diaphragm vibrates, changing the distance between two metal plates, which modifies the distance to record voltage changes and converts it into an audio signal.
