Abstract (en)
[origin: WO9002471A1] 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).
