  • Acoustic Valve Mechanisms
    Publication number: 20100111340
    Abstract: A valve for a personal auditory system is described. The auditory system is capable of converting between an acoustic signal and an electrical signal. The auditory system 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 includes a free floating electrode and a second electrode adjacent to free floating electrode. An electric signal that is generated by the second electrode moves the free floating electrode to substantially open or close the acoustic pathway.
