Dock Connector

The iPhone uses Apple's new Lightning dock connector to connect to your computer and other accessories. Unlike the 30-pin connector, it's reversible, so you can plug it into your phone in either direction. As this is one of the first Apple devices to use a new connector, it won't work with older third-party accessories without an adapter.

Speaker

On the bottom right of the new iPhone is a small speaker that's responsible for projecting speakerphone calls, music, movies, game noises, and any other miscellaneous noise. Because your device has just one speaker, it plays all audio in mono (on a single channel).
