Abstract
Magnetic headset, characterized in that it consists of a hollow casing, whose mouth is closed by a cover provided with holes of auditory permeability and between which the structured membrane is imprisoned by means of a fiber disc and a concentric internal tap of metal which undergoes the differential attractions of the flows, permanent and variable, and coming from a ceramic magnet and by polar pieces of sweet iron electromagnetized by coils housed in the shell itself.
