2. Electrodynamic moving-coil microphone
2.1 Operating principle
A moving coil made up of N turns of length L (total length = NL ) placed in a field of constant radial magnetic induction B is subjected to a force F (normal to B ) and moves at speed v, intersecting the induction lines (figure 10 ). It is therefore the seat of an induced electromotive force e.
The coil is attached to a diaphragm with surface area S. The assembly of coil and diaphragm is called the moving assembly.
The system...
