    Abstract: An electronic device is disclosed. The electronic device may include a sensing component positioned in an enclosure. The sensing component can determine ambient air pressure. In order for the sensing component to access ambient air, the electronic device includes a through hole in the enclosure. The through hole allows communication from the ambient air to the sensing component. In some instances, liquid becomes lodges in the through hole and reduces or inhibits the ability of the sensing component to determine the ambient air pressure. In order to expel the liquid from the through hole, the electronic device may include an air accumulation module designed to receive air from the internal volume, causing an increased air pressure within the air accumulation module. The air accumulation module can subsequently release the air in a direction toward the through hole. In this manner, the air can expel the liquid from the through hole.

    Abstract: A liquid-resistant module can be formed as a laminated construct having a housing, a cap, and a port membrane to inhibit liquid from passing across the membrane. The housing defines an internal duct extending from an inlet port to an outlet region. The cap defines an acoustic port and extends across the outlet region of the housing. The port membrane is attached to the cap and extends across the acoustic passage. The port membrane inhibits passage of liquid water through the membrane at differential pressures across the membrane less than a threshold pressure differential, and yet is gas permeable. The module can provide a liquid-resistant seal with an enclosure of an electronic device, and an enclosed microphone transducer or an enclosed loudspeaker transducer can be attached to the cap such that a port opening to or from the transducer is aligned with the acoustic port.
