Dynamic Microphone Basics
The most common types of microphones used by performers in bands, stage performances, or recording studios are Dynamic, Condenser (Large and Small Diaphragm), and Ribbon microphones. They all have a specific purpose and are not limited to what this booklet mentions. When selecting microphones, consider the following: a) What is the application? (Drums, Guitar Amp, Vocals). b) Is the microphone sensitive enough for the application? c) Does the microphone you have chosen enhance the sound you are trying to replicate – is this the sound you were looking for?
Dynamic Microphones
How do Dynamic Microphones Work? Dynamic microphones employ a diaphragm/voice coil/magnet assembly, forming a miniature sound-driven electrical generator. Sound waves strike a thin plastic membrane (diaphragm) that vibrates. A small coil of wire (voice coil) is attached to the rear of the diaphragm and vibrates with it. The voice coil is surrounded by a magnetic field created by a small permanent magnet. The motion of the voice coil in this magnetic field generates the electrical signal corresponding to the sound picked up by the Dynamic Microphone.

Notes Regarding Dynamic Microphones:
- It is recommended to always consider using a dynamic microphone unless the situation calls for a different application or special requirement.
- Dynamic mics are the most reliable of the types, but also the most difficult to achieve high sensitivities.
- Dynamic microphones are unsuitable at 4-5 feet away from a source. Always keep a dynamic microphone as close to the source as possible!
