Abstract (en)
[origin: EP0681412A2] Improvement in the closure plate and control unit of hearing aids to be inserted into the auditory meatus of the hard of hearing, also called intracanal hearing aids, characterized by an extremely reduced size, which unit is housed in an opening of the closure plate and fastened therein by means of rotating ratchet members; the unit is so shaped as to receive only a portion of the battery, namely the central portion, while the polar portions thereof are received in the opening formed in the closure plate; this shape makes it possible a further reduction in the size of the unit, the circular small cover thereof resting and being supported by the edge of the opening housing the unit rather than by portions of the body of said unit, thereby operating also as a cover for said opening. <IMAGE>
