1. A surface mountable package for containing a transducer, the transducer being responsive to sound pressure levels of an acoustic signal to provide an electrical output representative of the acoustic signals, the surface mountable package comprising:

  • at least a first member and a second member and a chamber being defined by the first member and the second member, the transducer being attached to a surface formed on one of the first member or the second member and the transducer residing within the chamber;

    the surface being formed with at least one patterned conductive layer, the patterned conductive layer being electrically coupled to the transducer;

    an outside surface of the surface mountable package comprising a plurality of terminal pads electrically coupled to the patterned conductive layer;

    a volume being defined by the transducer and one of the first member or the second member, the volume being acoustically coupled to the transducer; and

    one of the first member or the second member being formed to include an aperture, the aperture configured to permit the passage of an acoustic signal to the transducer.
