  • Internal vent structure for waterproof microphone acoustic cavity
    Patent number: 9930435
    Abstract: A method and apparatus are described for providing an acoustically-resistive air-permeable venting structure within a sealed microphone acoustic cavity. A microphone is mounted on a printed circuit board and positioned within a housing. A water-resistant membrane seals the microphone from an exterior of the housing, and a active acoustic cavity establishes an acoustical connection between the water-resistant membrane and the microphone. An acoustically-resistive air-permeable venting structure is formed in the body of the printed circuit board and connects to the active acoustic cavity either directly or via a separate vent path. The venting structure provides a viscous dampening effect by venting an active acoustic cavity of the electronic device to the rest of the enclosure sealed by the water-resistant membrane.
