Combined audio jack and mobile electronic device enclosure

Enclosures for electronic devices are provided. These enclosures can be integrally formed with a full or partial receptacle connector shell for receiving electrical connectors such as audio connectors or plugs. For example, an enclosure made from a polymer can be integrally formed with an audio jack shell in an injection molding process. As another example, an enclosure can be integrally formed with one or more full or partial walls of an audio jack shell to form a single piece of polymer or metal and the remaining walls of the audio jack shell can be overmolded or assembled to the polymer or metal walls of the audio jack and proximate portions of the enclosure to form a full or complete audio jack shell.
