  • an outer housing having a transducer mounting wall;

    a transducer mounting member having first and second walls which oppose each other, the transducer mounting member being affixed to the transducer mounting wall such that the first wall thereof abuts the transducer mounting wall; and

    a sound transducer mounted on the second wall of the transducer mounting member such that the sound transducer faces the transducer mounting wall to receive sounds passing therethrough;

    the transducer mounting member being formed with a first plurality of apertures extending from the first wall thereof adjacent the transducer mounting wall toward the transducer and terminating within the transducer mounting member, and a second plurality of apertures extending from the second wall thereof adjacent the transducer and terminating within the transducer mounting member;

    each of the second plurality of apertures extends substantially parallel to a respective one of the first plurality of apertures and is offset therefrom;

    each of the second plurality of apertures is connected to the respective one of the first plurality of apertures to provide a plurality of deviated passageways through the transducer mounting member from the transducer to the transducer mounting wall.
