Abstract
An ear-worn electronic device comprises a housing configured to be worn in, at or about an ear of a wearer, electronic circuitry disposed in or supported by the housing, a controller disposed in the housing and coupled to the electronic circuitry, and a rechargeable power source and charging circuitry respectively disposed in the housing. The charging circuitry is coupled to the controller and comprises first and second charge contacts situated at a wall of the housing. A user-actuatable control is operatively coupled to the controller and comprises a touch sensor coupled to the first and second charge contacts. The touch sensor comprises a threshold detector configured to distinguish between skin contact with the first and second charge contacts and contact between a conductive material more conductive than skin and the first and second charge contacts.
