Question:

How do microphones work

Author: Moaeed



Answer:

Microphones generate current from sound waves Sound waves hit a flexible diaphragm that is attached to a coil of wire wrapped around a magnet. The sound waves causes the coil of wire to move back and forth in the magnetic field which generates a current. The movement of the coil depends on the proeprties of the sound wave that hits the flexible diaphragm This is how microphones can convert the different sound waves into variations in current in a circuit
