Abstract: front page image
(EN)A microphone comprises a substrate (20), a microphone membrane (10) defining an acoustic input surface and a backplate (11) supported with respect to the membrane with a fixed spacing between the backplate (11) and the membrane (10). A microphone periphery area comprises parallel corrugations (24) in the membrane (10) and backplate (11). By using the same corrugated suspension for both the membrane and the backplate, the sensitivity to body noise is optimally suppressed.
(FR)L'invention porte sur un microphone, qui comprend un substrat (20), une membrane de microphone (10) définissant une surface d'entrée acoustique et une plaque arrière (11) supportée par rapport à la membrane avec un espacement fixe entre la plaque arrière (11) et la membrane (10). Une zone de périphérie de microphone comprend des ondulations parallèles (24) dans la membrane (10) et la plaque arrière (11). Grâce à l'utilisation de la même suspension ondulée à la fois pour la membrane et la plaque arrière, la sensibilité à un bruit corporel est supprimée de façon optimale.
