Condenser microphones use a pair of charged metal plates, one fixed (the backplate) and one movable (the diaphragm), forming a capacitor. When a sound wave hits the diaphragm, the distance between the two plates changes which produces a change in an electrical characteristic called capacitance.

How does a capacitor microphone work?
As the sound waves vibrate the diaphragm, the varying distance between the diaphragm and the back plate causes the voltage across the capacitor to change. This voltage is the electrical signal, rapidly fluctuating to mimic the pattern of the original sound waves.
What is the principle of microphone?
Just like we use our diaphragms to sing, microphones use their diaphragms to pick up sounds and convert them into electrical currents. A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. In some designs, the coil moves within a magnet.
What is the difference between capacitor and condenser microphone?
Condenser microphones are essentially a highly specialized capacitor. For those of you without an EE degree, a capacitor is a passive electrical component that is designed to temporarily store energy in an electric field. Capacitors work by using two plates in close proximity with one another.
What is capacitor condenser mic?
The electrostatic or condenser microphone is constructed with the diaphragm as one plate of a parallel-plate capacitor. The most popular form of this type of microphone is the electret condenser microphone, in which the plates are given a permanent electrical charge.
