Wireless and digital microphones
A
microphone is a device for converting acoustic power into electric power
that has essentially similar wave characteristics. Microphones convert
sound waves into electrical voltages that are eventually converted back
into sound waves thru speakers. They were first used with early telephones
and then radio transmitters.
A microphone system is designed to replace the cable that usually tethers
a wired microphone (or any acoustic transducer) to an amplifier. A system
begins with a typical microphone which responds to sound waves, and
delivers essentially equivalent audio frequency electrical waves to
an input of a transmitter. The transmitter "sends" a signal
to an associated receiver which is connected to the input of the sound
reinforcement amplifier, or mixer. The receiver "picks-up"
the transmitter signal, and then converts this signal to a usable audio
signal which is sent to the sound reinforcement amp or mixer.
In 1827, Sir Charles Whetstone was the first person to coin the phrase
"microphone."
In 1876, Emile Berliner invented the first microphone used as a telephone
voice transmitter. At the U.S. Centennial Exposition, Emile Berliner
had seen a Bell Company telephone demonstrated and was inspired to find
ways to improve the newly invented telephone
In 1961, First wireless microphone used in a film “Mutiny On
The Bounty” with Marlin Brando.
Today they are used for everything from hearing aids to the concert
stage. A younger generation may not even remember that microphones once
HAD wires!
