Patent ID: 8798304

Claim:
A valve for an auditory system, the auditory system capable of converting between an acoustic signal and an electrical signal, wherein the valve has an acoustic pathway through which an acoustic signal may travel between a first point exterior to the auditory system and a second point interior to the auditory system, the valve comprising: a housing; a magnetic member located within the housing capable of generating a magnetic force; an armature adjacent to the magnetic member wherein the magnetic member generates a magnetic force towards the armature; a coil adjacent to the armature, wherein energizing of the coil attracts or repels the armature to substantially open or close the acoustic pathway and wherein the coil remains in a substantially fixed location relative to the housing and is not directly connected to the armature; such that the opening and closing of the acoustic passageway is effective to operate the valve in an open position or a closed position; wherein the open position allows already-produced sound to pass through the passageway without the sound being modulated; and wherein the closed position prevents the already-produced sound from passing through the passageway.
