摘要： A cerumen trap for hearing aids comprises a sound channel and a plurality of perforations arranged in a stellate pattern around the sound channel which connect the sound outlet of an earpiece with the sound channel. A cylindrical component (1) with a connecting piece (3) which surrounds the sound channel can be inserted in the hearing aid. A number of angle pieces (4) with locking noses (5) are arranged on the periphery of the component (1). The sound outlet opening (2) can be closed off from the exterior by a cap (7) which has a locking groove (8) on the inner wall and which engages with the locking noses (5).

摘要： Un piège à cérumen pour prothèses auditives comporte un canal de son autour duquel sont agencées selon une configuration étoilée une pluralité de perforations qui relient la sortie de son d'un écouteur avec le canal de son. Un élément cylindrique (1) pourvu d'une tubulure de raccordement (3) entourant le canal de son peut être introduit dans la prothèse auditive. Un certain nombre d'éléments d'angle (4) dotés de taquets d'encliquetage (5) sont disposés à la périphérie de l'élément (1). L'ouverture (2) de sortie de son peut être fermée de l'extérieur par un capuchon (7) qui présente une rainure d'encliquetage (8) ménagée sur la paroi intérieure, et qui s'encliquette sur les taquets d'encliquetage (5).

摘要： A modular hearing aid for arrangement in a user's ear comprises a hollow plug (1) adapted to the ear canal and having a generally irregular conical shape and an exterior opening which is covered by a faceplate (2), in which a recess (8) is formed for removable arrangement of a battery (23) as well as an electronic module (4) comprising a microphone part (5), a signal processing part (6) and a sound reproducer (7). The recess (8) comprises a first region (9) for insertion of the battery (23) and a second region (10) coherent with the first region for placing of a socket part (11) of the electronic module (4), and at the edge of the recess (8) the faceplate (2) is formed with engaging means (12-16) for the socket part (11), whereas further parts of the electronic module (4) are placed below the faceplate (2). The recess (8) is formed such that at removal of the battery (23) the first and second regions (9, 10) together allow passage also of said further parts (6, 7) for removal of the complete electronic module.
