Abstract

A hollow tube device enclosing a personal sound link module is inserted into a tunnel (40) made through the soft tissue connecting the retro-auricular space (50) with the ear canal (30). The hollow tube device contains an acoustic transducer (65), located at the distal part (68) of an enclosed case, close to or inside the ear canal, an antenna (64) that receives and also potentially sends signals to a remote source, signal processing circuitry (67), telemetry circuitry (69), a power source (66) that powers the device, and possibly a microphone (63). Signals transmitted from a remote source are received through the antenna and telemetry circuitry, processed, and presented to the acoustic transducer, where they are converted to sound waves broadcast into the user'"'"'s ear canal. The remote source may be a radio station, radio receiver, CD player, DVD player, tape player, audio system, telephone, TV receiver or station, or other source of audio signals intended to be heard privately by the user.
