How does the work of a microphone

Microphone was to intensify and strengthen small noises, so they clearly audible and understandable, so as to facilitate communication distance. The first microphone was invented and developed to be used as a voice telephone transmitter. The word microphone is composed of two Greek words. They are micro-enterprises, which means that small and telephone, which means communication.
A microphone is a form of transducers, noise that changes from one form to another. It converts sound waves, as the existing model of atmospheric pressure, electrical signals, and finally return to sound waves by loudspeakers. There are various techniques, they can build a microphone, but the technique used is the most dynamic design, magnet.
In a dynamic micro sound waves emitted by a source of lead that movements in a thin membrane metal and a partner of the coil of wire. A magnetic field around the coil with a magnet and coil moves in this area, as a result of sound waves, it generates an electric current. The level of production is currently depending on the speed of movement, it is the speed and break.
The dynamic microphones are of two types of tape and reel mobile microphones. A ribbon microphone consists of a metal loop is thin. And it is balanced in a magnetic field. The tape is the electrical output of the microphone. The vibrations of the tape in the magnetic field generates an electrical signal.
Moving Coil The microphone is something else. Here is a small voice coil in the magnetic field. It is a membrane, whose coil is attached to this report. That you enter through a windshield. And then the diaphragm by sound waves. With the vibration of the membrane, the coil moves and generates a news electromagnetic induction.
Another popular type of microphone is the capacitor. Here, the membrane is mounted near a rigid plate and battery on the plate, which allows an electrical charge between them. The amount of the fee depends on the battery voltage, each surface of the membrane and the back plate and the distance between them. The distance between these changes in harmony with the movement of the diaphragm, in response to sound.
The microphone sensitivity depends on how much electrical power, a son. Each microphone is distortion. When he cancels by loud noises as sustainable overload that causes distortions in the diaphragm. This affects performance and sound quality even under normal volume.
The distortion is characteristic of the camera, what determines its price, and it depends on the amount of diligence in the construction and assembly of the membrane.
What you read is a simple statement, functions as a microphone. Although it has no information on the microphones, it gives you an idea about the functioning of them.
