Working of Microphone
We all know that in computers every process works in the principle of Input-Process-output cycle same principle used here also whenever a person speaks sound energy and waves entered into microphone and generates energy. When sound waves hit the diaphragm, it continuously varies (moves forward and backward) and coil also moved here. Here the coil cuts the magnetic field which is produced by permanent magnet inside the microphone, electric current runs through it. Current is used to drive the sound recording device which allows to store the sound and we can also able to magnify the current which converts electricity into louder sound finally creates the audio signal by using electrostatic principles.
What is a Microphone?
The microphone was developed by Emile Berliner in the year 1877. Microphone acts as an input device that is used to convert sound waves into electrical waves. it captures audio by conversion of sound waves into electrical signals which may be analog or digital. This process is implemented by using the latest high definitions and processing computers. Actually, the first microphone is based on the liquid mechanism, here the diaphragm was connected to a current needle which cannot produce clear speech. Besides the type of device microphone is designed for directionality let me give a clear example Omnidirectional microphone picks all sounds in any area but the disadvantage of using this is unable to focus with background noise. Microphones are used to capture sound in various applications such as music, podcasts, videos audio speeches, etc. The microphone is the best invention it makes and saves more energy by delivering speech with a good amount of efficiency.
