A microphone works by:
|
Rotating a stationary ball to adjust the pointer on a screen
|
|
Tracking the movement of a laser or LED light across a flat surface
|
|
Pressing keys down to generate different binary inputs
|
|
Turning analogue sound vibrations into electrical signals
|
Explanation:
Detailed explanation-1: -The dynamic microphone is constructed with a small magnet that oscillates inside a coil attached to the diaphragm. When a sound wave causes the diaphragm of the microphone to vibrate, the relative motion of the magnet and coil creates an electrical signal by magnetic induction.
Detailed explanation-2: -Microphones are a type of transducer-a device which converts energy from one form to another. Microphones convert acoustical energy (sound waves) into electrical energy (the audio signal).
Detailed explanation-3: -The transducer is the part of microphone actually detecting and converting the sound waves. This is also sometimes called an element. There are many different types of transducers.
