First Claim
Patent Images
1. A circuit for a hearing aid, the circuit comprising:
- an interface recessed into a housing of the hearing aid and including a plurality of contact elements for releasably coupling to a connector, at least one of the plurality of contact elements includes a first conductive lead spaced apart from a second conductive lead and is configured to produce an electrical signal when the connector contacts the at least one contact element and wherein the connector is configured to electrically couple the hearing aid with a remote electronic device when the connector is in contact with the interface to enable the hearing aid to receive at least one of a power supply or an audio signal;
a first power supply terminal;
a logic circuit coupled to the interface for receiving the electrical signal and configured to detect the connector in response to receiving the electrical signal via the interface; and
a switch including a first electrode connected to the first power supply terminal, a second electrode coupled to the first conductive lead, and a control terminal responsive to at least one of the logic circuit and a control circuit.
