Microphones are commonly used in every stage performance, music concert, television program and such other events. Generally, during a performance, sound waves are captured in microphones with the help of diaphragm, which experience a vibration when the waves get initiated into the microphone. Finally the original sound is received after the vibrations get converted into electrical signals. Among various types of microphones, laser microphones are the exclusive ones, with latest technical features. The technology of laser is quite interesting and a popular one. Laser microphones basically use the same technology while experimenting with the sound. They first of all detect the vibrations in a reflected laser beam and then convert them into audio signal. To say more, with the help of laser light, the laser microphones converts the acoustical sound waves to electrical signal, so that it can be processed and amplified for sound reproduction. The laser beam that it has must be reflected off a glass window or any rigid surface, which will vibrate corresponding to the nearby sound. This microphone has the ability to turn any vibrating surface into a microphone just by measuring the space between itself and the surface. This is because, while doing so, the little fluctuations in the space become the electrical signal of the sound. However, these types of microphones are designed in a typical way. The outer housing, which is cylindrical in shape, has spaced opening so that the sound waves can enter. There is also an inner housing, which too is cylindrical in shape and is positioned centrally inside the outer one. Then, to project the laser light into the space between the outer and the inner housing and a detector to receive the laser light that modulates the sound and produce electrical signals out of the waves entering the outer housing. The laser in the laser microphones is capable of measuring the accurate distance between itself and the surface where it is bouncing off, so in this way it can measure the fluctuation of that surface with the vibration of the sound waves. However, these kinds of microphones are used in movies as spy equipments. Besides this, there are other types of microphones too. Like, there are lavaliere microphones, contact microphones, parabolic microphones, which are generally used for musical purpose and are in demand. Among all these, the laser microphones are the latest ones but quite expensive and point to be noted is that it is not very portable. The best feature of the laser microphones is that it provides realistic and distortion free sound that usually was a problem with the older form of mics. Infact, the use of laser beams for sound reproduction has solved many technical problems. In the earlier forms there was only one sound channel that usually received sound from one direction. But the newest forms of microphones like the laser ones have multiple sound channels, which produce sound that are much more realistic and amazing. These types of microphones are even used in movies to give special sound effect.
