actually works. A working style-frame.
FIG.002 — MOVING-COIL DYNAMIC MICROPHONE · EXPLODED ASSEMBLY
Sound is just air pressure on the move. It pushes a thin diaphragm back and forth; a voice coil glued to that diaphragm rides up and down through a fixed magnetic field. A coil moving through a field generates a voltage — so the coil hands a tiny electrical copy of the sound out through the XLR. It is, in effect, a loudspeaker run in reverse.
