Understanding Microphone

Microphone is a device to convert sound vibrations into electrical vibrations. So the microphone to function as a source of audio signals.

There are several types of microphone:
1. Carbon Microphone
This type of microphone to change sound vibrations because of changing electrical resistance.
2. Condensor Microphone
This type of microphone to change sound into electrical vibration due to changes in electrical capacity.
3. Dynamic Microphone
This type of vibration microphone produce electricity because of the vibration coil in a magnetic field.
