Abstract
This application discusses a system that can include a master device and a slave device coupled to the master device via an audio jack connector. In an example, the master device and the slave device can be configured to exchange information via a single conductive path of the audio jack connector using a digital communication protocol. The single conductive path can be configured to conduct audio signals of an audio transducer and the slave device can include a depletion-mode transistor to complete a circuit including the audio transducer and the single conductive path in a first state, and to isolate the audio transducer from the single conductive path in a second state.
