Abstract:
A portable electronic device includes a housing member. The portable electronic device also includes a front cover coupled to the housing member and defining a top surface defining a portion of an exterior front surface of the portable electronic device, a bottom surface opposite the top surface, a peripheral side surface, and a chamfered edge extending from the bottom surface to the peripheral side surface. The portable electronic device further includes a display stack attached to the bottom surface of the front cover, an opaque coating positioned on at least a portion of each of the peripheral side surface, the chamfered edge, and the bottom surface and configured to absorb light emitted by the display stack, and a rear cover coupled to the housing member and defining a second portion of the exterior rear surface of the portable electronic device.
Abstract:
This disclosure describes features and methods of formation of a data port for a portable electronic device. The portable electronic device includes a device housing having a wall defining a data port opening. An anchoring feature is formed along a portion of the wall defining the data port opening. A structural support member is positioned within the data port opening and reinforces the data port opening. A polymer material fills a gap between the structural support member and a portion of the wall defining the data port opening. The polymer material engages the anchoring feature to retain the structural support member within the data port opening.
Abstract:
Electronic equipment may include structured fabric. Structured fabric may be used as a protective case or cosmetic cover for an electronic device, may be used to form a band that holds an electronic device against a user's body, or may be used to cover one or more openings in an electronic device. Structured fabrics may be soft and pliable while maintaining the ability to hold a given shape without added support. Structured fabric may be formed by laminating fabric such as warp-knit fabric with a stiffener such as polymer film. Structured fabrics may include openings through which signals such as optical or audio signals pass. To maintain the geometry and shape of the openings in the structured fabric without covering the openings, the stiffener and adhesive that are attached to the fabric may be cut to form a pattern of openings that align with the openings in the fabric.
Abstract:
An audio system that adjusts one or more beam patterns emitted by one or more loudspeaker arrays based on the preferences of users/listeners is described. The audio system includes an audio receiver that contains a listener location estimator, a listener identifier, and a voice command processor. Inputs from the listener location estimator, the listener identifier, and the voice command processor are fed into an array processor. The array processor drives the one or more loudspeaker arrays to emit beam patterns into the listening area based on inputs from each of these devices. By examining the location, preferred usage settings, and voice commands from listeners, the generated beam patterns are customized to the explicit and implicit preferences of the listeners with minimal direct input. Other embodiments are also described.

Abstract:
An array of electrical components may be mounted in openings in an electronic device housing. The housing may have a cylindrical shape or other curved shape. A support structure such as a hollow cylindrical tube may be mounted within the interior of the housing. The electrical components may have terminals that mate with corresponding contacts on a flexible printed circuit. Interconnect paths on the flexible printed circuit may be used to route signals for the electrical components. The flexible printed circuit may be wrapped into the shape of a cylindrical tube and may be mounted on an interior surface of the cylindrical housing or on the exterior surface of the support structure.
Abstract:
An array of electrical components may be mounted in openings in an electronic device housing. Gaskets may be used to seal the electrical components to a housing wall. The housing wall may be planar or may have a cylindrical shape or other curved shape. The electrical components may be mounted to the housing wall using screws and nuts. Each nut may have a central member with opposing stops at the ends of the central member. An opening in each central member may receive a screw to allow the nut to rotate between an installation position and a locked position. The openings in the housing wall may have scalloped extensions that allow the nuts to clear the housing wall while the components are being inserted into the housing. Following installation, the nuts may be rotated into the locked positions.
Abstract:
An electronic device may have a rigid support structure to which electrical components are mounted. The rigid support structure may be an electronic device housing structure such as a housing wall having openings that receive the electrical components. The electrical components may have electrical component connectors. A printed circuit board may be used to convey signals for the electrical components. Connectors may be mounted to the printed circuit board. Lateral shift accommodation structures may be formed between the electrical component connectors and the electrical components or in the vicinity of the connectors on the printed circuit to allow the connectors on the printed circuit to mate with the electrical component connectors of the rigidly mounted electrical components.
Abstract:
An electronic device may have housing structures, electrical components, and other electronic device structures. Adhesive may be used to join electronic device structures. Adhesive may be dispensed as liquid adhesive and cured to form adhesive joints. Adhesive joints may be debonded. Chain reactions may be initiated by applying a localized initiator such as a chemical or localized energy to the adhesive. Once initiated, the chain reaction may spread throughout the adhesive to cure the adhesive, to globally change adhesive viscosity, or to weaken the adhesive to facilitate debonding. Local changes to adhesive may also be made such as local increases and decreases to adhesive viscosity. Chain reaction curing may be used to cure adhesive or debond adhesive that is hidden from view within gaps in the electronic device structures. Viscosity changes may be used to control where adhesive flows.
