Abstract: The technology provides a device, such as a wireless earbud, with capacitive sensing capabilities. For instance, the device may include a housing, and a conductive support positioned inside the housing. The device may further include one or more processors configured to measure a combined capacitance of a plurality of electrodes at the conductive support. Based on the combined capacitance, the one or more processors may detect that the conductive support is inserted into an ear. The one or more processors may then operate the device in a first mode based on detecting that the conductive support is inserted into an ear.

Abstract: A case (100) is provided for housing and charging one or more wireless devices (180), such as wireless earbuds. The case (100) includes capacitive sensing circuitry (120) for detecting whether the wireless devices (180) are positioned inside the case (100) based on a capacitance of the wireless devices (180). The case (100) also includes a transceiver (150) for transmitting data to and receiving data from the wireless devices (180). When the wireless devices (180) are positioned inside the case (100), an electrical component (110) inside the case operatively connects the capacitive sensing circuitry (120) and the transceiver (150) of the case (100) to the wireless devices (180). The case (100) further includes one or more processors (140) for controlling the capacitive sensing circuitry (120), the transceiver (150), and the electrical component (110).
