Abstract
Embodiments of the present disclosure relate to a headphone or speaker assembly that contains two or more audio components that are configured to be magnetically coupled together by use of a complementary magnetic pole configuration in the headphone or speaker assembly to provide one or more useful functions. These useful functions may include elements that are able to sense that the two or more audio components are in contact with each other, or are at least proximate to each other, so that their audio playback capability can be suspended while they are in this unused state. A sensor located within one of the components can detect a change in the magnetic field and generate an electronic signal indicating a clasped condition.
