Griffin AirCurve Acoustic Amplifier for iPhone

Imagine hearing your iPhone loud and clear, without using earphones or powered speakers. AirCurve turns your iPhone into a no-power-drain alarm clock on your nightstand, or a mini sound system that never needs batteries or adapters. This cleverly designed acoustic amplifier for your iPhone collects the sound from the built-in speaker of your iPhone, amplifies it in coiled waveguide within the base, and projects it into the room. The waveguide has been engineered to deliver amazing amplification you'll swear there are full-sized speakers in there.
