Patent ID: 7856111

Claim:
A hearing aid device comprising: a customized shell having a shape adapted to fit in the helix lock area of an ear of a hearing-impaired person; processing circuitry mounted within said shell that processes incoming audio signals to produce an audio output dependent on a hearing-impairment of the hearing-impaired person; a face plate disposed at an exterior of the shell; a sound-conducting tube having a first end interfacing with said face plate and a second end adapted to terminate in the ear canal of said ear, said sound-conducting tube being adapted to snugly fit into the concha of the ear and, in combination with said shell, exerting a pressure to retain the shell and the sound-conducting tube in said ear; and said sound-conducting tube terminates in the ear canal with a free tube end containing a receiver that is connected to the processing circuitry via wires that run along a length of the sound-conducting tube, the free tube end comprising a domed-element covering said free end and fitting into the ear canal.
