Abstract: This disclosure describes a portable electronic device that includes an inductive charging receiver for receiving power wireless from a charging device. The portable electronic device includes a device housing including a wall having a channel formed in an interior-facing surface of the wall. The portable electronic device also includes an inductive coil assembly for receiving power wirelessly that is coupled to the interior facing surface. The inductive coil assembly is a flat coil that includes concentric loops of electrically conductive material that define a central opening. A first electrical lead extends away from a peripheral portion of the flat coil and a second electrical lead extends from the central opening, into the channel formed in the back wall and beneath one side of the concentric loops.

Abstract: A charging assembly for wireless power transfer. In embodiments, the charging assembly comprises a housing, a cap structure, a ferrimagnetic sleeve, an inductive coil, a magnet, a printed circuit board assembly (PCBA), and a four-pin connector extending from a bottom surface of the PCBA. A ridge of the cap structure can be coupled to a lip of the housing. The housing can include a bottom housing surface having an aperture, and a sidewall extending between the bottom housing surface and the lip that extends outward from the sidewall along a perimeter of the housing parallel to the bottom housing surface. The four-pin connector can extend through the aperture of the housing. Some embodiments are directed to a charging device that incorporates the charging assembly.

Abstract: An electronic device and methods for inductively charging an electronic device using another external electronic device. The electronic device may include an enclosure, a battery positioned within the enclosure, and an inductive coil coupled to the battery. The inductive coil may have two or more operational modes, including a power receiving operational mode for wirelessly receiving power and a power transmitting operational mode for wirelessly transmitting power. The electronic device may also have a controller coupled to the inductive coil for selecting one of the operational modes.

Abstract: A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

Abstract: An enclosure is formed by coupling an outer cover to a back enclosure piece. The enclosure defines an interior volume for receiving components of an electronic device. The back enclosure piece is formed from a metal frame component and a non-metal outer cover. A metal layer overlaps the metal frame component and the outer cover within the interior volume. The metal layer has a thickness that provides support and shatter resistance to the non-metal outer cover. The metal layer can form an inductor of a wireless power transfer circuit.

Abstract: Embodiments describe a wireless power receiving module to receive magnetic flux for wireless power transfer. The wireless power receiving module includes a receiver coil comprising a single length of wire wound into a plurality of turns, an electromagnetic receiver shield coupled to a first side of the receiver coil, a ferrite layer coupled to a second side of the receiver coil opposite of the first side, the ferrite layer positioned to redirect magnetic flux during the charging event to improve charging efficiency, and a thermal mitigation shield comprising a thermally conductive layer adhered to an electrically conductive layer where the electrically conductive layer is coupled to ground, and where the ferrite layer is sandwiched between the thermal mitigation shield and the receiver coil.
