The iPhone’s built-in speaker has never been one of its strong points, nor has its battery life. So taking both of those issues into consideration Griffin has created yet another non-powered ‘speaker’ for the iPhone 4 with their AirCurve Play. But instead of using electromagnetism and paper cones, the AirCurve features an “internal engineered waveguide” made of polycarbonate plastic that promises to boost the volume of the iPhone 4′s own speaker by +10dB. The iPhone is held securely in place via a rubber gasket with the side buttons and dock port still accessible, and thanks to a built-in kickstand the acoustic amplifying ‘dock’ is able to sit in either a portrait or landscape hands-free orientation. $19.99 available directly from Griffin.
