For recording a microphone needs to be connected to a preamplifier. Other than this the condenser microphone & the piezoelectric microphone are some of the procedures usually follow.
There are many processes to do that but the most common is a dynamic microphone that uses a coil of wire suspended in a magnetic field. The Function of a MicrophoneĪ microphone or mike converts the air pressure variations of a sound wave to an electrical signal. Later Thomas Edison has refined this into a carbon-button transmitter in 1886. Later German inventor Johann Philipp redesigned an early transmitter that used a metallic strip attached to a vibrating membrane that would produce intermittent current but a better result came with 'liquid transmitter' designed by Scottish-American Alexander Graham Bell in 1876.ĭavid Edward Hughes invented a carbon microphone in 1870 that is the direct prototype of today's microphones and was critical in the development of telephony, broadcasting, and the recording industries.
In 1665 Robert Hooke was the first to invent the process of stretched wire with a cup attached at each end for transmission.
