How A Microphone Works
As mentioned above, a microphone works independently of any loudspeakers, headphones, or other playback systems.
How does a microphone work? A microphone coverts sound into electrical signals by means of a movable diaphragm. The mic diaphragm moves according to varying sound pressure and is a key component in the mic transducer. The movement of the diaphragm within the transducer causes the creation of an electrical microphone signal.
Dynamic microphone transducers convert sound into mic signals via electromagnetic principles.
Condenser microphone transducers convert sound into mic signal via electrostatic principles.
In any given microphone, the moving diaphragm results in an electrical signal.
From the diaphragm, the signal may travel through some other microphone components, such transistors and transformers, before being outputted by the microphone.
