  • Patent number: 7130420
    Abstract: An acoustic transducer assembly comprising an acoustic transducer body having one or more apertures through which an audio signal is passed. Two housing parts when assembled provides a acoustic transducer cavity for containing the acoustic transducer body and a resilient sealing gasket, and the acoustic transducer cavity has a sound passage through the housing wall. The resilient sealing gasket provides a channel for transferring said audio signal from said one or more apertures to the sound passage through the housing wall. The housing parts have an inclined wall part that transfers a biasing force originating from the two housing parts and acting on the acoustic transducer body to a force acting on the resilient sealing gasket in order to provide a sealing between the resilient sealing gasket and the sound passage through the housing wall.
