1. Dynamic Microphones

2. Step-By-Step  Let’s take a step by step look into how the microphone process’s sound.

3. Sound Source  The sound source creates sound wave vibrations in the air.

4. Microphone Picks up Sound  These vibrations of the sound waves are picked up by a microphone.

5. Conversion In  The microphone converts the vibrations into an electrical signal. Your ear does the same thing

6. Signal Is processed  The electrical signal is processed

7. Conversion Out  The output device converts the electrical signal back into sound waves

8. 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.

9. 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.

10. 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
