How are condenser microphones different?

The principle is different

1. Ordinary microphone: Using a polymer material diaphragm with permanent charge isolation, headphone manufacturer，the sound signal is converted into an electrical signal.

2. Condenser microphone: Use the change in the size of the capacitor to convert the sound signal into an electrical signal.

different structure

1. Microphone: The human voice is used to vibrate the diaphragm through the air, and then the electromagnetic coil winding on the diaphragm and the magnet surrounding the moving coil microphone form a magnetic field cutting to form a weak fluctuating current.

2. Condenser microphone: There are two metal plates, one of which is coated with an electret film (mostly polyperfluoroethylene propylene) and grounded, and the other plate is connected to the gate of the field effect transistor.

Different advantages

1. Microphone: The output voltage generated on the microphone is equal to the output voltage generated by the inherent noise of the microphone itself, and the sound pressure of the sound wave is equal to the equivalent noise level of the microphone.

2. Condenser microphone: It not only relies on precise mechanism manufacturing technology, but also combines complex electronic circuits to directly convert sound into electrical energy signals. It has extremely superior characteristics innately.
