Application
Ideally suitable for small scale boardrooms and meeting rooms, Large Meeting Room, Large lecture seminar.
The condenser microphone has two metal plates, one of which is coated with electret film (mostly perfluoroethylene propylene) and grounded, the other plate is connected to the gate of the field effect transistor, and a diode is connected between the gate and the source. When the electret diaphragm itself is charged, the electric quantity of surface charge is Q, and the capacitance between plates is C, the ground voltage U = q / C is generated on the electrode head. When it is subjected to vibration or air
