Abstract
An earbud is provided having an earbud housing. Formed on a surface of the earbud housing are first and second conductive elements configured to form a first capacitive element. When the earbud is located within a charging case, the first and second conductive elements are arranged with a third conductive element mounted to an inside surface of the charging case in a location designed to influence a capacitance of the first and second conductive elements. An evaluation circuit of the earbud is positioned within the earbud housing and electrically coupled to the first and second conductive elements. In response to the first and second conductive elements having a capacitance value above a threshold, the evaluation circuit provides an indication the earbud is within the charging case. In another embodiment, a method is provided for detecting the earbud is within the charging case.
