Abstract

Abstract An improved hearing aid ofthe type intended to be completely received in the external auditory meatus of the user, comprising an outer housing or cap (10) of frustoconical shape having an upper circular opening (11) and a circular closure plate (20) therefor. mounting and containing the electric and electronic part of the hearing acid, namely a microphone (12), an amplifier (13), an electroacoustic transducer (14) and a potentiometer-switch device (PT) and the powering battery, wherein the closure plate (20) has two spaced apart counterbored sockets (22, 22') each receiving a screw (21, 21') and means (15n 15', 16, 16') adapted to be joined to said cap (19) adjacent said opening (11) and to threadingly receive said screws (21, 21') and a seat (23) for the battery provided with a cover (116) hinged on the outer face of the closure plate (20) about a pin (115) mounted parallel to the latter so that said cover (116) can rotate between a lowered closing position wherein the cover (115) lies against the closure plate and a raised open position angularly spaced apart by 90°.
