Griffin Technology's latest iPhone accessories were unveiled yesterday at the opening of Apple Expo Paris: A new iPhone and iPhone 3G dock that uses absolutely no electronics in it's sound-amplifying coiled waveguide, and a protective iPhone 3G case with a built-in lens cover that makes taking macro and close-up pictures easier and more clear with the phone's built-in camera.

The AirCurve for iPhone and iPhone 3G is a clear polycarbonate acoustic amplifier designed to provide more powerful sound from the iPhone’s built-in speaker without the need for added electronics. It uses a coiled waveguide within its base, which can be easily seen thanks to its clear materials, to amplify the sound, and also offers a pass-through slot to allow for charging of the while docked. It will retail for $20.

Griffin also introduced the Clarifi for iPhone 3G, a new polycarbonate case featuring a built-in sliding close-up lens that enhances the macro and close-up functions of the iPhone 3G’s built-in camera, letting users shoot crisp images from as little as four inches away. Other features include open access to all ports and controls and Griffin’s EasyDock slide-off bottom for docking. It will retail for $35.

Both the Griffin AirCurve and Clarifi should be available in October.
