发明名称 Audio jack system
摘要 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.

主权项 1. A system comprising: a master device; a slave device coupled to the master device via an audio jack connector; wherein the master device and the slave device are configured to exchange information via a single conductive path of the audio jack connector using a digital communication protocol; wherein the single conductive path is configured to conduct audio signals of an audio transducer; and wherein the slave device includes a depletion-mode transistor configured to complete a circuit including the audio transducer and the single conductive path in a first, unpowered, default state, and to isolate the audio transducer from the single conductive path in a second state.
