Abstract: front page image
(EN)Embodiments of the invention provide microphone assemblies for hearing aids which are resistant to moisture and debris. An embodiment provides a microphone assembly for a CIC hearing aid comprising a microphone housing including a housing surface having a microphone port, a fluidic barrier structure coupled to the housing surface, a protective mesh coupled to the barrier structure and a microphone disposed within the housing. The microphone housing can be sized to be positioned in close proximity to another component surface such as a hearing battery assembly surface. At least a portion of the housing surface and/or the barrier structure are hydrophobic. The barrier structure surrounds the microphone port and is configured to channel liquid and debris away from entry into the microphone port including matter constrained between the housing surface and another surface.
(FR)Certains modes de réalisation de l'invention concernent des sous-ensembles microphone destinés à une prothèse auditive résistant à l'humidité et aux impuretés. Un mode de réalisation de l'invention concerne un ensemble microphone destiné à une prothèse auditive CIC comprenant un boîtier de microphone, lequel comprend une surface de boîtier possédant un port de microphone, une structure de protection contre les fluides couplée à la surface du boîtier, un maillage de protection couplé à cette structure de protection et un microphone placé à l'intérieur du boîtier. Ce boîtier de microphones peut être dimensionner de façon à être placé à proximité étroite d'une autre surface de composant telle qu'une surface d'ensemble accumulateur de prothèse. Au moins une partie de la surface du boîtier et/ou de la structure de protection est hydrophobe. La structure de protection autour du port de microphone est agencée de façon à canaliser les liquides et les impuretés à distance de l'entrée du port de microphone, y compris les matières coincées entre la surface du boîtier et une autre surface.
