Abstract
A package comprises: a transducer; a substrate comprising an acoustic port, with the transducer attached to a surface of the substrate and over or adjacent to the acoustic port; and a venting mechanism for venting air or sound pressure from a device comprising the package, with the venting mechanism being affixed to the substrate and partially surrounding the acoustic port, and with the venting mechanism being dimensioned to filter out audio frequencies.
Claims18
A packaged device comprises:
- a transducer;
- a package substrate having an acoustic port, with the transducer supported over a surface of the package substrate and over or adjacent to the acoustic port;
- and
- a venting mechanism affixed to the package substrate, the venting mechanism proximate to and partially surrounding the acoustic port of the package substrate, the venting mechanism comprised of a material patterned to provide first and second adjacent sidewalls along a surface of the package substrate adjoined at a first end of the venting mechanism and that are spaced by a gap that provides a vent for venting air or sound pressure from an enclosure volume of the device.

A device comprising:
- a transducer;
- a package substrate supporting the transducer and comprising an acoustic port;
- and
- a venting mechanism affixed to the package substrate, the venting mechanism proximate to and partially surrounding the acoustic port of the package substrate, the venting mechanism comprised of a material patterned to provide a pair of first and second adjacent sidewalls that are adjoined by a portion that includes an open ring of the material, and with the pair of first and second adjacent sidewalls along the package substrate and which first and second adjacent sidewalls are spaced by a gap of a fixed gap width and which gap provides a vent for venting air or sound pressure from an enclosure volume of the device.
