Abstract: An electronic watch may include a housing at least partially defining an interior cavity divided into at least a first volume and a second volume, a pressure-sensing component positioned within the first volume, a speaker positioned within the first volume, a processor positioned within the second volume, a battery positioned within the second volume, and a barometric vent that allows air pressure equalization between the first volume and an external environment.

Abstract: A head-mountable device can include adaptable components, which move to comfortably engage the face of the user and to exclude light from an external environment. A head-mountable device can include a light seal that includes discrete portions that bend and/or pivot as needed to conform to a face of the user. Such mobility allows the portions to be oriented with respect to corresponding regions of the face, so that an engagement surface of each portion directly engages the corresponding region of the face to maximize the surface area of contact. Such a configuration can be provided while also providing an aesthetically pleasing appearance by providing one or more covers that form continuous, breathable surfaces with the desired opacity.

Abstract: An electronic device includes an enclosure having a transparent cover defining a touch-sensitive surface, a display positioned within the enclosure and below the transparent cover, and a haptic device configured to produce a haptic output along the touch-sensitive surface. The haptic device may include a battery element electrically coupled to the display, a magnetic element, and a coil assembly fixed with respect to the enclosure and configured to induce an oscillatory movement of the battery element parallel to the display to produce the haptic output. In other examples, the coil assembly may be coupled to the battery element and the first and second magnetic elements may be fixed with respect to the enclosure.

Abstract: An electronic device such as a wristwatch may have a housing with metal portions such as metal sidewalls. The housing may form an antenna ground for an antenna. An antenna resonating element for the antenna may be formed from a stack of capacitively coupled component layers such as a display layer, touch sensor layer, and near-field communications antenna layer at a front face of the device. An additional antenna may be formed from a peripheral resonating element that runs along a peripheral edge of the device and the antenna ground. A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Abstract: An electronic device may include a rear housing wall, antenna resonating element, coil, sensor board, and antenna grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures and the rear housing wall. The grounding ring structures may include concentric ring-shaped traces. The ring-shaped traces may be separated by at least one gap. The ring-shaped traces and the gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna resonating element to a ground trace on the sensor board while blocking currents at relatively low frequencies. This may allow the ground trace to form part of an antenna without substantially impairing wireless charging efficiency of the coil.

Abstract: An acoustic module, such as a microphone or speaker module, includes an acoustic membrane that vibrates to produce acoustic waves and an acoustic cavity through which acoustic waves produced by the membrane travel. A liquid removal mechanism removes liquid from the acoustic cavity. Such a liquid removal mechanism may include the acoustic membrane, heating elements, hydrophobic and/or hydrophilic surfaces, and so on. In some cases, the liquid removal mechanism may remove liquid from the acoustic cavity upon connection of the acoustic module and/or an associated electronic device to an external power source.

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.
