Dynamic Microphones
Step-By-Step
Let’s take a step by step look into how the microphone process’s sound.
Sound Source
The sound source creates sound wave vibrations in the air.
Microphone Picks up Sound These vibrations of the sound waves
are picked up by a microphone.
Conversion In The microphone converts the
vibrations into an electrical signal.
Your ear does the same thing
Signal Is processed
The electrical signal is processed
Conversion Out
The output device converts the electrical signal back into sound waves
Transduction
This process — converting acoustical energy into electrical energy or electrical energy back into acoustical energy —is called transduction.
Therefore microphones and loudspeakers are examples of transducers.
Dynamic Microphone Dynamic microphones are also called moving-coil microphones.
Inside a Dynamic Microphone Dynamic Microphone's Working Procedure: 1. Sound waves hit the diaphragm of the mic. 2. The very sensitive diaphragm vibrates. 3. Vibrations move the coil of wire attached to the diaphragm. 4. The coil is suspended around a magnet. 5. Magnets have a naturally occurring magnetic field. As the coil
moves, it disrupts the pattern of the magnetic field. 6. As the coil cuts across the magnetic field lines, an electrical
current is induced in the coil. This is an example of electromagnetic principles.
Dynamic Mic’s
Extremely durable, dependable, and can withstand high sound pressure levels
Versatile because they don't require a power source
Downside: tend to be heavier, larger, and less sensitive than most other types
