Philippi electrical components Germany Philippi model Philippi price

Philippi electrical components are energy conversion devices that convert sound signals into electrical signals. Categories include moving-coil, condenser, electret, and the recently emerging silicon microphones, as well as liquid microphones and laser microphones. Most microphones are electret condenser microphones, which operate using a polymer diaphragm with permanently isolated charge. The simplest switch structure in Philippi electrical components consists of two metal pieces called "contacts"; when the two contacts touch, they complete the current circuit, and when they do not touch, the current circuit is open.
