Microphone protecting device for use in housing of e.g. behind-the-ear apparatus, has membrane carrier including large aperture directed outwardly from hearing aid and small aperture directed to aid and connected with hearing aid housing

The device (1) has a sound-transmissive and waterproof membrane (3) connected with a flat edge (7) of a funnel-shaped membrane carrier (2), where the sound-transmissive membrane is made of PTFE. The membrane carrier comprises a large aperture (5) directed outwardly from an interior part of a hearing aid, and a small aperture (6) directed to the interior part of the hearing aid. The membrane carrier is manufactured as an injection molded part and releasably connected and welded with a hearing aid housing by a gasket. The membrane is covered by a shroud. Die vorliegende Erfindung beschreibt einen Mikrofonschutz (1') für ein wasserdichtes Hörgerätegehäuse (10'), das einen Membranträger (2') und damit verbunden eine schalldurchlässige und wasserdichte Membran (3') aus Polytetrafluorethylen (PTFE) aufweist. Der Membranträger (2') weist eine in sich geschlossene Form mit einer großen, vom Hörgeräteinneren nach außen gerichteten Öffnung (5') und einer kleineren, zum Hörgeräteinneren gerichteten Öffnung (6') auf.
