An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret. The electret's permanent electric dipole provides a constant charge Q on the capacitor. Sound waves move the diaphragm, changing the capacitance C, which produces a corresponding voltage change across the ...
Phone connector (audio) Phone plug mated in a phone socket. The plug's grooved tip is held firmly by the socket's spring tip contact. When not mated, this spring instead connects to the flat switch contact for detecting a plug. A phone connector is a family of cylindrically -shaped electrical connectors primarily for analog audio signals.
