Abstract: An electronic device with a port is disclosed. To expel liquid in the port, the port includes modifications to form a capillary pressure gradient with the liquid, causing uneven capillary forces to act on the liquid in the port. For example, the port may include an asymmetric profile with one section having a curved profile and another section having one or more linear profiles that join at an edge. The edge may form a relative higher curved surface as compared to the curved profile. As a result, the capillary pressure gradient may exert a higher capillary pressure in a location associated with the edge, as compared to a capillary pressure along the curved profile. The capillary pressure gradient causes ambient air into the port along the edge, and separates the liquid from the edge, allowing gravity to overcome atmospheric pressure and causing removal of the liquid from the port.

Abstract: A differential pressure gradient micro-electro-mechanical system (MEMS) microphone for measuring an acoustic characteristic of a loudspeaker. The microphone includes a MEMS microphone housing and a compliant membrane mounted in the MEMS microphone housing, the compliant membrane dividing the MEMS microphone housing into a first chamber and a second chamber. The first chamber includes a primary port open to a first side of the compliant membrane and the second chamber includes a secondary port open to a second side of the compliant membrane, and the primary port and the secondary port are tuned with respect to one another to control a pressure difference between the first side and the second side of the compliant membrane such that at least 10 dB of attenuation is observed in a microphone signal output relative to a microphone having a sealed first or second chamber.

Abstract: An electronic device comprising having an enclosure with an enclosure wall separating a surrounding environment from an encased space. The enclosure wall includes a top portion having an acoustic channel extending from the encased space to the surrounding environment and a bottom portion. A microphone assembly module positioned within the encased space, and having a microphone acoustically coupled to a sound inlet port that is aligned with the acoustic channel and an air permeable water resistant membrane. A first support member is dimensioned to translatably couple the microphone assembly module to the top portion of the enclosure wall and translate the microphone assembly in response to a pressure change within the acoustic channel, and a second support member is dimensioned to translatably couple the microphone assembly module to the bottom portion of the enclosure wall.

Abstract: An acoustic module is coupled to an acoustic passage. The acoustic module includes an acoustic transducer coupled to a diaphragm. A controller or other circuitry measures an impedance of the acoustic transducer. Based on the impedance, the controller determines whether the impedance indicates that the acoustic passage is blocked. The controller may determine that the acoustic passage is blocked by liquid that is present in the acoustic passage. When the controller determines based on the impedance that liquid is present in the acoustic passage, the controller may drive out, purge, and/or otherwise remove the liquid, such as by using the acoustic transducer to vibrate the diaphragm.

Abstract: An electronic device having a microphone behind a water resistant, air-impermeable membrane is disclosed. Embodiments include a trapped volume of air between the membrane and the microphone. A barometric equalization element may define an acoustic leak path, e.g., a tortuous leak path, between the trapped volume of air and an encased space within a casing of the electronic device. Other embodiments are also described and claimed.

Abstract: A speaker or microphone module includes an acoustic membrane and at least one pressure vent. The pressure vent equalizes barometric pressure on a first side of the acoustic membrane with barometric pressure on a second side of the acoustic membrane. Further, the pressure vent is located in an acoustic path of the speaker or microphone module. In this way, differences between barometric pressures on the different sides of the acoustic membrane may not hinder movement of the acoustic membrane. In one or more implementations, the pressure vent may be acoustically opaque. As the pressure vent is located in the acoustic path of the speaker or microphone module, being acoustically opaque may ensure that the pressure vent itself does not interfere with the operation of the speaker or microphone module.
