Abstract:
1. A semi-permanent hearing device adapted to be inserted entirely within a wearer's ear canal past the aperture thereof for long-term use therein, comprising; a scaling retainer adapted to be seated in the bony portion of the ear canal along the longitudinal axis and in direct contact with the immobile wails thereof when said device is fully inserted within the ear canal of the wearer; a receiver assembly including a receiver for supplying acoustic signals to the tympanic membrane of the wearer, said receiver assembly being arranged and adapted to mate with said retainer for positioning in the bony portion of the ear canal; a microphone assembly including a microphone for receiving receiving incoming acoustic signals; a self-contained battery assembly for powering said device; and a flexible connector connecting, said receiver assembly to said self-contained battery assembly and said microphone assembly so that said microphone assembly is flexibly supported without substantially contacting the cartilaginous portion of the ear canal so as to be substantially non-occluding therein with minimal or no contact with the walls thereof, whereby to avoid substantial interference by said microphone assembly with hair and production of cerumen and debris within said ear canal.
