BandedIn a ribbon microphone, a thin ribbon is suspended in a magnetic field. Sound waves move the ribbon, changing the current flowing through it.capacitorA condenser microphone is actually a capacitor in which one pole of the capacitor moves in response to sound waves. Motion changes the capacitance of the capacitor, and these changes are amplified to produce a measurable signal. Condenser microphones usually use a small battery to supply voltage to the capacitor.
CrystalSome crystals change their electrical properties when they change shape (for an example of this phenomenon, see how quartz watches work). By connecting the diaphragm to the crystal, the crystal will generate a signal when the sound wave hits the diaphragm.
