Abstract:
A headphone is disclosed herein. The headphone includes a wireless transceiver, a wired communication module, a power storage device, a speaker, and control circuitry. The wireless transceiver and the wired communication module and the wireless transceiver are connected to the speaker via the control circuitry. The control circuitry is configured to determine whether to control the speaker according to data received via the wired communication module and the wireless transceiver and to seamlessly transition control of the speaker from data received from one of the wired communication module and the wireless transceiver to the other of the wired communication module and the wireless transceiver.
Abstract:
Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.
Abstract:
Methods, systems, and apparatus for determining whether an accessory includes particular circuitry. A host device may measure a first voltage and a second voltage received from an accessory, where the voltages are provide through the accessory from a power source. Before measuring the second voltage, the host device may send an instruction to the accessory instructing the accessory to alter an impedance of the power path between the power source and the host device, and the host device may draw at least a threshold amount of current from the power source via the accessory. The host device may then determine whether the accessory includes particular circuitry based on the relationship between the first voltage and the second voltage.
Abstract:
A case for a pair of earbuds includes a housing having cavities to receive the pair of earbuds and charging circuitry that is configured to initiate charging of the pair of earbuds when an earbud detector detects that the earbuds are inserted within the cavities.

Abstract:
A case for a wireless electronic listening device (e.g., a pair of wireless earbuds) is configured to house a pair of wireless earbuds and charge the earbuds when they are in the case. The case is further configured to receive media received by the wireless earbuds and transmit the media to a non-wireless output device connected to the case. The case may further include its own wireless radio that can wirelessly communicate audio to the wireless earbuds when the earbuds are not in the case. The case may further include an input port to receive an audio signal from a non-wireless source and may be configured to wirelessly transmit the audio received from the source to the wireless earbuds.
Abstract:
Simplified interfaces for charging and communication between accessories and docking stations. One example may provide an interface for charging and communication between an accessory and docking station where data and a charging voltage are provided over the same pins. An accessory may determine that it is in a powered docking station by receiving a charging voltage. The accessory may determine that it is in an unpowered docking station by providing a voltage to the unpowered docking station, where the unpowered docking station uses the voltage to power an oscillator. The oscillator signal may be received by the accessory, which may use the presence of the signal to determine that it is in an unpowered docking station.
Abstract:
Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.
Abstract:
Connector systems that may facilitate the insertion of connector inserts into connector receptacles, may eliminate the need for dedicated contacts to detect a connection, and may provide connector inserts that are rotatable even when the functions of the contacts on the connector inserts are not symmetrical.
Abstract:
A case for a pair of wireless earbuds includes a lid and a lid sensor configured to generate a detect signal when the lid is moved from a closed position to an open position. The case further includes circuitry configured to, in response to receiving the detect signal, send a signal to the wireless earbuds to turn them on and to initiate a pairing sequence between the wireless earbuds and an electronic device.
