Microphone Mic

mechanism of growth and uses of Button Microphones

A microphone is also known as carbon microphone or the button carbon emitter. The design of a carbon microphone is very simple one. It consists of two metal plates separated by small pieces of carbon. One of the pieces between the two parties to the outside. Its role is to work as a diaphragm.

The mechanism by which a button turns the microphone is quite complex. The sound wave that is caused by moving particles of air strikes the plate, which acts as a diaphragm. The initial pressure were there on change the microphone, resulting from the change in electrical resistance between the plates. Exchange rate difference of the pressure wave velocity of movement of plate. The next step is below the current flow from one plate to another. The change in current can be used to pass, even a power system becomes a signal.

Advantages and disadvantages of a microphone Button

One of the basic advantages of a microphone is coal that has high output, such as obstruction or impedance of the quantity is low. The high output voltage signal CD audio is very weak, and that itself is an amplifier so there is no need for amplifiers or external batteries.

Several areas where physical engagement is high, the use of carbon microphones more. For example, in the opera theater where the singers are busy with the movement, carbon microphone use of flexibility along smoothly with a clear understanding of the music. In addition clubs modern, most microphone button when DJ is used to create musical mixers.

But carbon microphones were rejected by the broadcasting system, after the 1920s due to low production of sound quality, which often have no noise or hiss level. In addition, the frequency response for the carbon microphone was limited.

History button microphone

The year 1978 has seen TA Edison Emile Berliner and both claim the invention of the issuer of carbon. Both sides had a hard fight for the rights of patent, which was ordered after the federal court entitling the Edison invention.

Other uses of carbon Several micro

Use carbon microphone and an amplifier
Surprisingly carbon microphone can also be used as an amplifier. telephone repeater earlier this attribute has been put into service. With this arrangement, the receiver Phone mechanically connected with a microphone to enhance carbon weak signals and send them via the telephone line. In the 1930s also has been used in some audio equipment, in particular in the helmet. In the 1950s, however, the transistors have replaced their earlier counterparts.

Early in the amplitude modulation or AM radio base also depended on the carbon microphone voice modulation transmitter.

Use of modern microphone button
In certain developing countries traditional telephone equipment still in use. Some third world countries and use certain niche applications. An example is the 104 C, Shure, which is quite compatible with some existing equipment.
