Where the Quadcast differs from those tiny headset mics is in the size and plurality of the diaphragm. When the sound pressure level (SPL) gets quieter, the diaphragm (or three of them in this mic's case) can move back to their normal position and the electrical field widens again, lowering the signal sent to the amplifier. There’s an electrical field between the diaphragm and backplate because the diaphragm is conductive, so when it’s pushed back by sound pressure levels, the electrical field narrows and a louder signal is sent to the amplifier. The mic’s built around an electret condenser design, which is broadly the same as the mic on the end of most headset swingarms: A diaphragm translates changes in sound pressure levels into electrical current using a backplate, which holds static charge, and an amplifier.
