A first electronic device, electronically coupled to a second device for supplying a charge to the second electronic device, tracks the voltage requirements of the second device and dynamically adjusts its output voltage upwards or downwards to match such requirements. The second electronic device may provide feedback to the first electronic device through a feedback loop. The feedback may include an indication of the voltage requirements and/or instructions for adjusting the voltage output of the first electronic device. The second device may be, for example, a wearable audio device, while the first device is a case for the wearable audio device.

Dynamic adjustment of charging voltage supplied from a first device to a second device

An antenna is provided for a wearable personal computing device, such as an earbud. The antenna integrates with other components of the wearable device, such as an input control. For example, the antenna may at least partially surround a portion of a touchpad input at a surface of the device that is exposed when the device is worn. In one example, the antenna shares a ground plane with the touchpad. In another example, the antenna includes two nested traces, wherein a first trace is connected to ground and a second trace is connected to an antenna feed.

Antenna for wearable devices

A case () is provided for housing and charging one or more wireless devices (), such as wireless earbuds. The case () includes capacitive sensing circuitry () for detecting whether the wireless devices () are positioned inside the case () based on a capacitance of the wireless devices (). The case () also includes a transceiver () for transmitting data to and receiving data from the wireless devices (). When the wireless devices () are positioned inside the case (), an electrical component () inside the case operatively connects the capacitive sensing circuitry () and the transceiver () of the case () to the wireless devices (). The case () further includes one or more processors () for controlling the capacitive sensing circuitry (), the transceiver (), and the electrical component ().
