General Purpose Speaker for school Project
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 of Condenser Microphone:
- 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.
- It is used in sound recognition module.
