Advantages and disadvantages of moving coil microphones

A moving coil microphone functions on the basic principle of electromagnetic induction. It has a copper wire coil, which when it moves in the magnetic field generates a voltage. Then is induced in the coil in proportion to its amplitude of vibration, which in turn depends on sound pressure. A moving coil microphone contains a diaphragm that is exposed to sound waves. The diaphragm carries a coil placed in the field magnetic.

Moving coil microphones are cheap and strong and are renowned for their excellent performance in the live performance and touring. They are especially suitable for close miking bass and guitar speaker cabinets and equipment drum. They are also ideal for live vocals as they have a resonance peak of about 5k hz providing an innate drive, which otherwise improving speech, or sing brilliantly.

You will find there are many types of microphones in motion the coil. One of them is the Shure SM58, which is a classic microphone. This is an industry standard microphone designed primarily for live performances. They are strong and yet do not require high power. However, the drawback of these microphones is that the coil reduces the high frequency response. Therefore, not much more suitable for applications used in the study, where the focus is on quality and subtlety. It is of basic importance, including high-quality recording acoustic instruments or vocal microphone voice. However, in some cases are used in the studies for the recording of instruments. Moving coil microphone also is the first choice for snare drums, and also very popular in guitar amplifiers.

One of the biggest advantages of a coil microphone Mobile is the robust construction of these microphones for tough use. They are also ideal because they have high sound pressure level. It is a strong device and it is impossible to break one without doing it intentionally. They are durable and can withstand pressures of any kind.

Because of these benefits and basic characteristics of movement microphones roll is commonly found in places where road configurations. These devices are designed in a simple design and manufacture of microphones roll moves in a large number, therefore, the cost of these microphones is quite affordable.

Although these microphones are commonly used for various live performances and are ideal device for her, however, has its disadvantages as well. One of the main disadvantages of this microphone is that of the coil is relatively heavy and makes it difficult to move quickly. And, therefore, makes it difficult to obtain high frequency response of these microphones. Just Thus, from the output of the coil depends on its speed, very low frequencies will result in too little production.

When you look at the advantages and disadvantages mentioned above, you may find the disadvantages are far outnumbered by the advantages, then you can say that this is mainly the reason for the microphones moving coil increasingly popular device. Trucks are ideal for musical instruments and voices. And they are also ideal for live sound reinforcement.
