Abstract: A case for an electronic device such as a head-mounted device may have a main housing portion that separates an interior region from a surrounding exterior region. The main housing portion may have an opening through which the head-mounted device is received into the interior region. Flexible protruding portions of the main housing portion may form a flexible tab and a flexible flap. To make size adjustments to the interior region, the flexible tab may slide within an opening in a cover. The cover may be configured to move between an open position in which the opening is uncovered and a closed position in which the head-mounted device is enclosed within the interior region by the main housing portion and the cover. Deformable protrusions in the case may be used to seal openings in the head-mounted device when the device is in the interior region.

The linkage assembly can include a first arm pivotably attached to the frame, the first arm comprising a first end and a second end, a second arm pivotably attached to the first end and attached to the facial interface, and a third arm pivotably attached to the second end and attached to the facial interface.

Abstract: A head-mounted device may have a housing containing displays that display images a user when the head-mounted device is worn by the user. The head-mounted device may include a light-shielding structure or light seal coupled to the housing and configured to rest on a nasal region of the user. The light-shielding structure may include flexible members and/or fabric members. For example, the flexible members may be elastomeric members having perforations that allow the light-shielding structure to conform to the facial features of the user around the nasal region, while maintaining rigidity. Additionally, the light-shielding structure may block environmental light from entering the eye boxes when the head-mounted device is worn by the user. Rigid or semi-rigid members may be added on or within the light-shielding structure to provide additional rigidity and support as the device is worn by the user.

Abstract: A head-mounted device may include a main housing portion and a temple housing portion. Displays in the main housing portion may be configured to present images that are viewable from eye boxes. A light-blocking cover may extend between the main housing portion and the temple housing portion and may be configured to prevent outside light from reaching the eye boxes. The light-blocking cover may have a stretchable outer fabric layer and an inner light-blocking layer formed from fabric or other suitable materials. The light-blocking cover may include slack in the inner light-blocking layer so that the inner light-blocking layer can accommodate movement of the main housing portion relative to the temple housing portion without sacrificing opacity. The slack may be heat-set, molded, or covered with a layer of elastic so that the slack returns to a retracted state within the temple housing portion after being expanded.

Abstract: Wireless earbuds may be provided with adjustable-shape housings. The housings may have bendable portions. Bendable metal members, hinges, or other flexible structures may be used in forming bendable structures for the earbuds. Electrical components may be covered by a layer of molded foam.

The housing may be bent or otherwise adjusted between two or more states such as a normal, non-sleep, walking state in which the housing is expanded for normal operation while a user is sitting or walking and a sleep state in which the housing is bent to enhance comfort while sleeping. The wireless earbuds may have illumination systems, sensors, and other components.

Abstract: An electronic device may be formed from acoustically permeable textile layers and voice coil layers. The voice coil layers may output sound through the textile layers. The textile layers and voice coil layers may be foldable or bent in one or more directions to allow the electronic device to be placed in expanded, collapsed, or folded configurations to allow for improved portability. Additionally, the textile layers and voice coil layers may be folded or bent to place the electronic device in cylindrical, conical, and other configurations to allow for improved sound output from the voice coil layers. The electronic device may also include light-emitting components between the textile layers that emit light through one of the textile layers to form indicators or images for a user of the device. The electronic device may have a plurality of sensors to allow user interactions to control the output of the electronic device.

Abstract: A wearable device can provide an audio module that is operable to provide audio output from a distance away from the ears of the user. For example, the wearable device can be worn on clothing of the user and direct audio waves to the ears of the user. Such audio waves can be focused by a parametric array of speakers that limit audibility by others. Thus, the privacy of the audio directed to the user can be maintained without requiring the user to wear audio headsets on, over, or in the ears of the user. The wearable device can further include microphones and/or connections to other devices that facilitate calibration of the audio module of the wearable device. The wearable device can further include user sensors that are configured to detect, measure, and/or track one or more properties of the user.

Abstract: An accessory for wireless earbuds can include a first receiving portion defining a first cavity sized to receive and retain a first earbud and a second receiving portion defining a second cavity sized to receive and retain a second earbud. Each receiving portion can include a charging component to electrically couple with the respective earbud. The accessory can include a flexible portion connected to the first receiving portion and the second receiving portion, the flexible portion at least partially defining an internal volume, and a battery disposed in the internal volume and electrically coupled with the charging components.
