Abstract
A transducer port assembly comprising: a frame defining an acoustic chamber having an opening to an ambient environment and one or more interior sloping surfaces coupled to an acoustic port of a transducer; an acoustic mesh coupled to the opening to the ambient environment; and a blocking member coupled to the acoustic mesh to acoustically close a portion of the acoustic mesh.
Claims21
A transducer port assembly comprising:
- a frame defining an acoustic chamber having an opening to an ambient environment and one or more interior sloping surfaces coupled to an acoustic port of a transducer and the one or more interior sloping surfaces defining a bottom portion of the acoustic chamber such that the acoustic chamber comprises a greater height near a side wall than near the acoustic port;
- an acoustic mesh coupled to the opening to the ambient environment;
- and
- a blocking member coupled to the acoustic mesh to acoustically close a portion of the acoustic mesh.

A portable electronic device comprising:
- an enclosure defining an interior chamber separated from an ambient environment surrounding the enclosure;
- a frame defining an acoustic chamber having an opening to the ambient environment and one or more interior sloping surfaces coupled to an acoustic port of a transducer positioned within the interior chamber of the enclosure, and the one or more interior sloping surfaces define a bottom portion of the acoustic chamber and are inclined upwards when moving in a direction from a side wall of the frame defining the opening to the acoustic port;
- an acoustic mesh coupled to the opening to the ambient environment;
- and
- a blocking member coupled to the acoustic mesh to acoustically close a portion of the acoustic mesh.

An earbud comprising:
- an earbud enclosure defining an interior chamber separated from an ambient environment surrounding the earbud enclosure;
- a frame defining an acoustic chamber having an opening to the ambient environment and one or more interior sloping surfaces defining a bottom surface of the acoustic chamber having a frustoconical shape surrounding an acoustic port of a microphone positioned within the interior chamber of the earbud enclosure;
- an acoustic mesh coupled to the opening to the ambient environment;
- and
- a blocking member coupled to the acoustic mesh to acoustically close a center portion of the acoustic mesh.
