Wireless microphone is a simple microphone but no wires attached. Previously people had an idea that a microphone has to be big and must have many cables. But times have changed. And eventually the design and technology of the microphones has also changed.
Microphone History Wireless is very interesting. There are many companies and individuals who claim to be the inventors of this specific type of microphone.
In 1951, John F. Stephens developed a wireless microphone. It made for a musical sea. All the singers, players were given their own microphone. And they were all wireless.
In 1957, Sennheiser, a manufacturer of audio equipment German who was working with the German broadcaster Norddeutscher Rundfunk call showed a microphone, that was wireless. This system is marketed under the name of Mikroport through Telefunken from 1958.
Beyerdynamic, a manufacturer of equipment Germany said Hung. C. Lin invented the wireless microphone. It was then called transistophone. Production began in 1962. They also claimed that was first used in a movie called "My Fair Lady in 1964. And it was used by Rex Harrison in the film.
To end the cable was not in all an easy task. It took a lot of transmission technologies, standards and frequencies to make this move. This transmission is possible in microphone radio waves with frequencies from VHF and UHF, AM, FM, etc. There are some low-cost microphones. Many of them use infrared light. However, this infrared microphone need a line of sight between the receiver and microphone. But more expensive models do not require this.
Some of the work on the model often lump. However, do not use advanced models. They work on a user selectable frequency. Use of this often helps to avoid interference. Also helps to use multiple number of microphones at the same time.
Advanced versions of wireless microphones provide a wealth of facilities. It gives full freedom of movement for the wearer. You must be thinking how. Simple. Because the microphone is wireless, you can save anywhere on your body. Only must be connected and you can move freely with them. Whether you are inside your home or away. Since this microphone has no cable, no cable option very problematic.
Wireless microphone is essentially of two types, the handheld and body pack.
The handheld microphone seems that the conventional microphone. But his body is slightly larger than conventional ones. And so is able to accommodate the battery and transmitter.
Body Pack is actually a small box. Have the battery and transmitter in it. But there is a microphone himself. It is attachable to the strap. It has a cable that connects the microphone lavalier, guitar or a headset.
Today there are many popular brands available for this microphone. They offer a lot of new and innovative services. Sennheiser, Shure, Lectrosonics, Technical Audio, AKG, Samson technologies are all big names in this industry microphone.
