What are different types of microphones?

There are many ways to classify different types of microphones. They are often distinguished by a directional pattern in which they raise the sound or type of converter they have. Another common way, although for most purposes it can be considered too general, their categorization is according to portability or simply according to their specific purpose.

The most general ways of classification of microphones is to look at one of the two categories - wireless and cable units. Those who are wireless can transmit their signal to a amplifier with a wireless receiver, usually a radio frequency. Transmission requires an on -board power source, usually standard batteries. Some types use rechargeable batteries. With the cable microphone, the power and audio signal must be transmitted by the cable. These are very useful information for those who need the ability to pick up a file or ignore sound from specific directions. The most common direction microphone is the cardioid that captures the sound in the half circle of 180 ° Cclamps. There is also a small place directly behind the microphone where you can raise the sound. The Uni-Direction microphone raises the sound from only one direction and omnidirectional sound in all directions.

In addition to these main types of microphones, there are other directional options. Usually it is a variant of one of the aforementioned types. For example, there is a super or hyper cardioid that can raise the sound very well from directly before or directly behind. Bin-arral or two-way microphone can do the same, but from both sides. This is particularly useful for the production of stereo records.

Another common way to classify the types of microphones is to distinguish a vario -American converters. For example, capacitor microphones use DC electricity to polarize internal boards that are used to convert sound into energy. Dynamic microphones, by far the most popular choice, use the coil in the magnetic field. Sound vibrates the coil that forDukes energy. Electret microphones use a plastic piece that carries a permanent charge as a converter, and peacock microphones use a very thin piece of aluminum for the converter.

different types of microphones can be used in a wide range of situations. For example, cardioid units are commonly used for live performances. Ribbon Mics is used to record a studio where there is less chance that they are damaging. Bidirectional microphones can be used in radio and television studios.
