Assignee: BOSE CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An audio system comprising:
a set of audio devices, each comprising:
an electrode for detecting an electrical waveform, wherein the electrode comprises at least one of a capacitive electrode or an inductive electrode; and
a controller coupled to the electrode,

wherein the controller in a first one of the audio devices is configured to instruct the electrode in the first audio device to transmit an electrical waveform that is detectable by the electrode in a second one of the devices for indicating physical proximity of the first audio device to the second audio device, and in response to detecting the electrical waveform, the controller in the second audio device initiates a proximity-based action,
wherein the electrode in the first audio device comprises the capacitive electrode comprising a capacitive touch electrode, wherein the electrode in the second audio device comprises the capacitive electrode, and wherein the controller in the first audio device is configured to alternate, in a repeating pattern, between:
instructing the capacitive electrode in the first audio device to transmit the electrical waveform detectable by the capacitive electrode in the second audio device, and instructing the capacitive electrode in the first audio device to transmit an additional electrical waveform for detecting a user touch command at a capacitive touch interface connected with the capacitive touch electrode.
