Abstract

L'invention concerne un transducteur acoustique (1), en particulier pour un capteur ultrasonique, lequel comprend un boîtier (5), au moins un élément de découplage (9a) et un groupe fonctionnel (2). Le groupe fonctionnel (2) comprend une membrane en forme de godet (7) et au moins un élément transducteur électroacoustique (3). La membrane en forme de godet (7) comprend une membrane oscillante (8) et une paroi périphérique (6) ainsi qu'au moins un élément transducteur électroacoustique (3), l'élément transducteur (3) étant conçu pour exciter la membrane (8) de façon à la faire osciller et/ou pour convertir les oscillations de la membrane (8) en signaux électriques. La membrane en forme de godet (7) et au moins une partie du boîtier (5) sont formées à partir d'une matière plastique. L'élément de découplage (9a) est conçu pour découpler mécaniquement en vibration la membrane en forme de godet (7) et/ou l'au moins une partie du boîtier (5) de l'environnement extérieur du transducteur acoustique (1). L'élément de découplage (9a) selon l'invention est intégré dans la membrane en forme de godet (7), en particulier dans la paroi (6) de la membrane en forme de godet (7), et/ou dans l'au moins une partie du boîtier (5).
