Microphones are used in many applications such as astelephones, tape recorders, hearing aids, moving image production, live engineering and recording, radio and television broadcasts and on computers to record sound, VOIP, and for non-acoustic purposes such as ultrasonic examinations.
The microphone is a device that is made to capture waves in the air, water or hard material and translate it into an electrical signal. The most common method is through a thin membrane that produces some proportional electrical signals. Most of the microphones used today for the use of electromagnetic generation audio is a dynamic microphone, condenser microphone changes capacitance or piezoelectric generator to produce signals from mechanical vibrations.

Use of various types of microphones
The condenser microphone reaches the range of cheap instruments to high-quality instruments. They generally produce high-quality audio signals and are now a popular choice in laboratories and recording studio applications. They need resources, provided generally from the microphone input from a small battery.
Professional microphones often use external power supply for reasons of quality perception. Power is needed to set the capacitor plate voltage, and also required for internal signal amplification to useful output levels. The condenser microphone is also available with two diaphragms, signals from which can be connected electrically as to provide various polar patterns such as cardioid and omnidirectional.
