You can use various portable speakers to enjoy your favorite music. But if you want an innovative way to amplify the sound of your iPhone 4 or 4S, the horn speaker may be able to catch your eyes.
The horn speaker is a passive audio amplifier that measures 165 x 97 x 97mm, weights 30g, and designed for iPhone 4 and iPhone 4S.
