Abstract
Improved microphone, characterized essentially by behaving a magnetic device consisting of two coils wound on respective support reels, supported in turn on the center of a radiated structure that forms a fence laterally, whose front face houses a vibrating membrane held by its peripheral edges and provided with a ferric element in its central part, which faces and parallel to two heads centered with respect to the core of the radiated structure and derived from two ferric pieces located inside the coils, said parts having included, between their ends later, a permanent magnet constituting the magnetic field of the device.
