Dynamic Microphones

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
