A microphone is a device that changes the information from one type to another. A microphone is also known as an electroacoustic transducer. A variety of automatic techniques can be used in building microphones. Microphones create a very small amount of current, which create sense when we consider just how light the moving parts must be to exactly go behind sound waves.
Microphones are transducers which sense sound signals and produce an electrical image of the sound, like they create a voltage or a current. There are many different types of microphone, variety from the old condensers to the current piezo electrics. Different types of microphones are used like Condenser microphones, electrets microphone, Dynamic microphones, Carbon microphones and Ribbon microphones.
Microphones are normally used in television, radio, performance, telephones, and public address systems, and also in other extraordinary applications. Microphones are as well classified according to how well they pick up sound from certain directions.
