Abstract
Miniaturized hearing aid intended for a deep insertion into the auditory meatus of people who suffer from hearing problems, or "peritympanum" hearing aid, comprising a hollow body, a closure plate therefore provided with a cavity for housing the battery and with a small closing cover for said cavity operating as a movable battery holder shifting between a closed position supplying the contacts and an open position cutting the power supply of the battery, wherein the necessary thong for removing the hearing aids from the auditory meatus controls the movement of the battery holder from the closed position to the open position.
Claims21
An improved miniaturized hearing aid intended for a deep insertion into the auditory meatus of a person who suffers from hearing problems comprising:
- a hollow body (CCV);
- a closure plate (PC) for said body having a cavity (12) for housing a battery (BT) having two poles (PP and PN) to supply power to operative circuits of the hearing aid (TSI);
- and
- a closing cover (CPB) for said cavity (12) having locking means cooperating with matching means housed in said cavity (12) for locking the cavity (12) in the closed position, said closing cover being hinged so as to pivot and rotate toward and away from said cavity (12) and being shaped so as to house said battery (BT) so that said battery moves together with said cover (CPB),
- said miniaturized hearing aid (TSI) further having a removal thong (LC) with an inner end fastened thereto and having the free end (EST) in the pinna (PDG) of the ear (OCH) of said person, and first and second electrical contacts (16 and 34) for the two poles (PP and PN) of said battery (BT), each contact (16 and 34) being disposed in said cavity (12) so as to be in electrical contact with the respective battery pole when said cover (CPB) is in the closed position, the first of said contacts (16) biasing said battery (BT) upwardly so as to cause said cover (CPB) to open when said locking means are disengaged and cause said second contact (34) to detach from the respective pole of said battery (BT), so as to cut the power supply to said operative circuits and place the hearing aid (TSI) in the OFF position, the inner end (25) of said thong (LC) being fastened to the hearing aid (TSI) in such a way that pulling on said thong (LC) opens said cover (CPB) and switches off the hearing aid (TSI).
