What Is the Electret Condenser Microphone?

- May 14, 2018-

The Electret Condenser Microphone uses an electret material that can hold a permanent charge and therefore does not need to supply power to the capacitor. However, general electret microphone components have built-in electronic circuits to amplify signals, and therefore still need to be powered at low voltage (conventional voltage is 1.0V-10V). This microphone is currently widely used in consumer electronics products.
