Therefore, a junction field effect transistor is connected into the microphone for impedance conversion. FET is characterized by high input impedance and low noise figure. The common FET has three electrodes: active electrode (s), grid electrode (g) and drain electrode (d). Here, a special FET with another diode between the internal source and grid is used. The purpose of the diode is to protect the FET from strong signal impact. The gate of the FET is connected to a metal plate. In this way, there are three output lines of electret microphone. That is, the source s is generally blue plastic wire, the drain D is generally red plastic wire and the braided shielding wire connecting the metal shell.The basic structure of the microphone consists of an electret film coated with metal on one side and a metal electrode with several small holes on it (the back is called the back electrode). The surface of the electret is opposite to the back electrode, and there is a very small air gap in the middle to form a flat plate capacitor with the air gap and the electret as the insulating medium and the metal layer on the back electrode and the electret as the two electrodes. There is an output electrode between the two poles of the capacitor.
