  • Circuitry for detecting jack plug insertion or removal
    Patent number: 11852694
    Abstract: The present disclosure relates to circuitry for detecting connection of a plug of an audio accessory device to a socket of an intermediate cable that is connected to a host device, wherein the plug of the accessory device is of a different type than the socket of the intermediate cable. The circuitry comprises a monitoring unit comprising a first terminal configured to be electrically connected to a first socket contact of the socket that is in electrical contact with a first plug contact of the plug when the plug is fully received in the socket; and a second terminal configured to be electrically connected to a second socket contact of the socket that is in electrical contact with a second plug contact of the plug when the plug is fully received in the socket.
