    Abstract: An electronic device having a pressure sensor configured to determine pressure is disclosed. The electronic device includes an enclosure defining an internal volume. The enclosure may include a sidewall with an external opening that provides a vent for the internal components. To reduce the response of the pressure sensor (that is, the time required to detect a pressure change), the pressure sensor may secure with an internal wall of the enclosure. Further, the internal wall includes an opening defining an air pocket significantly smaller than the internal volume. When the pressure sensor is mounted to receive air via the air pocket, the pressure sensor may respond faster to pressure changes, as compared to receiving air circulating throughout the internal volume. This is due in part to an amount of airflow passing through the air pocket causing a greater pressure change throughout the air pocket as compared to the internal volume.

    Abstract: A liquid-tolerant acoustic device assembly includes a housing with an acoustic aperture connected to a through hole in the housing. An acoustic device such as a microphone or speaker that includes a liquid resistant membrane is coupled to the through hole utilizing a gasket. A protrusion is positioned between the through hole and the gasket. The configuration of the assembly may be tuned such that liquid present in the through hole is allowed to exit and/or functioning of the acoustic device is not impaired by the presence of the liquid in the through hole. The assembly may be incorporated into an electronic device.

    Abstract: An electronic device having a pressure detection system is disclosed. The electronic device may include one or more elements designed to detect pressure exerted on the electronic device. In some embodiments, the electronic device includes a membrane and a detection mechanism, both of which bend in response to a pressure change at the membrane. The membrane may be electrically coupled with a circuit that detects the bending of the membrane and correlates the bending with a pressure change at the membrane. A can may be hermetically sealed with the membrane and surround the circuit to shield the circuit from liquid ingress. In some embodiments, a light transmitter and light receiver are used to detect the bending of the membrane. The light may reflect from the membrane at different angles, based upon a shape of the membrane, and contact the receiving element at different locations, corresponding to pressure change.

    Abstract: An acoustic port of acoustic device is covered with a mesh and/or other structure that resists entry of liquid and/or other materials into the acoustic device. Apertures of a housing that are separated by an umbrella section are coupled to the acoustic port such that the umbrella section may cover the acoustic port. In this way, when liquid enters one or more of the apertures, the umbrella section may direct the liquid away from the mesh such that pressure from the liquid upon the mesh may be reduced. As such, potential damage to the mesh and/or internal acoustic device components may be mitigated. In some implementations, the apertures may be covered with an additional mesh. Such additional mesh may further reduce the pressure of entering liquid on the mesh covering the acoustic port of the acoustic device.

    Abstract translation: 声学装置的声学接口用被阻止液体和/或其它材料进入声学装置的网状物和/或其它结构覆盖。 由伞形部分隔开的壳体的孔连接到声学端口，使得伞形部分可以覆盖声学端口。 以这种方式，当液体进入一个或多个孔时，伞形部分可将液体引导离开网，使得来自网上的液体的压力可能减小。 因此，可以减轻对网孔和/或内部声学装置部件的潜在损害。 在一些实施方案中，孔可以用附加的网覆盖。 这种另外的网可以进一步降低在覆盖声学装置的声学端口的网状物上进入液体的压力。
