Abstract

A personal electronic device includes a multi-function jack that has at least one contact configured for both power and data connections. In an exemplary embodiment, the jack is based on an industry standard audio or barrel jack for compatibility with standard audio or barrel plugs. The shared power and data contact eliminates the need for personal electronic devices, such as mobile telephones, to have separate connectors and/or custom connectors for different types of peripheral devices.
