میکروفون خازنی ( میکروفون الکترت ) بسته دوعددی

Description:
An electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.

The microphone is an acoustic-electric conversion device (also called a transducer or a sensor), which is exactly the opposite of a horn (electricity → sound). It is the two terminals of the sound equipment, the microphone is the input, and the speaker is the output.
An Electret microphone is a type of condenser microphone that comes with a permanent charge built into it.
