Condensor Microphone

Condenser Microphone:
The condenser microphone, or capacitor microphone or electrostatic
microphone is a device which converting from sound energy into
electrical energy. It’s working as a parallel plate capacitor and works
on the principle of a variable capacitance. It consists of two plates,
one fixed (called the back plate) and the other moveable (called
Diaphragm) with a small gap between them. An electric potential charges
the plate. When sound strikes the diaphragm it starts moving, thereby
changing the capacitance between the plates which in turn results in a
variable electric current to flow.

Features:

• Small in size.
• Low cost.
• Easy to use.
• Light in weight.
• Applications of Condenser Microphone:
• It is used in Amplifier.
• It is used in Clap switch project.
