Abstract
A communication device configured for use in a user's ear canal including a sealing mechanism configured to acoustically seal a section of the ear canal and a sound conduit in acoustic communication with a sound source. The sound conduit has a first and second opening, a conduit housing, and a vent opening. To provide a reliable adjustment for the venting of sound waves between a sealed section of the ear canal and an ambient environment outside the sealed section, an acoustic valve having a valve member is moveably coupled with the conduit housing, which moveable coupling is configured to provide a relative motion of the valve member and the conduit housing, such that by such relative motion the acoustic valve provides for opening the vent opening, closing the vent opening, and/or adjusting a size of the vent opening. The communication device further includes an electrical actuator to activate the relative motion.
