Dynamic microphones can be divided into two types: Moving coil microphones and ribbon microphones. Dynamic microphones often have the advantage that they are more robustly built and thus optimally adapted to the conditions on stage. In addition, at least moving coil microphones are less sensitive to impact noise or handling noise.
In a moving coil microphone, wound copper wire in the form of a coil is attached to a moveable diaphragm. This coil dips into the air gap of a fixed permanent magnet (hence also the name). If an acoustic signal moves the diaphragm and therefore also the moving coil, the surrounding magnetic field induces an AC voltage into this coil, which reproduces the audio signal relatively accurately. This AC voltage is already the output signal from the microphone exerted between contacts 2 and 3 of the XLR plug.
Have a look at the moving coil microphone M 88 TG.
In ribbon microphones, a very thin aluminium strip (i.e. the ribbon that gives the microphone its name) vibrates instead of the diaphragm/coil unit. Its output signal is adjusted to standard microphone inputs using a transformer.
Our two ribbon microphones, the M 130 and M 160, work according to this principle.
