First is the dynamic mic, which will often be used on the snare, bass drum and sometimes on the toms. A dynamic mic functions just like a speaker, only in reverse, with the movement of the diaphragm in turn moving a coil in relation to a magnet, creating an electrical signal.
This mic is good for picking up mid-range and is sturdy enough to take the occasional miss-hit. Most dynamic mics use a cardioid pattern, which means they reject sounds coming from behind them while also boosting bottom-end when placed close to the subject.
