Extra Sound... no Extra Batteries

Boost audio volume without adding any additional power? It seems a violation of the laws of thermodynamics, but amazingly the AirCurve is a cleverly-designed acoustic amplifier that turns your iPhone into a no-power-drain alarm clock on your nightstand, or a mini sound system that never needs batteries or adapters.

The AirCurve looks like a simple, elegantly minimal stand for your iPhone. But inside is a coiled waveguide "horn" that collects the sound from the built-in speaker of your iPhone, amplifies it (by about 10 decibels), and projects it into the room. AirCurve's waveguide has been mathematically engineered to deliver amazing amplification -- you'll swear there are full-sized speakers in there. And AirCurve's see-through translucent polycarbonate body lets you appreciate the graceful curves inside that do all the work. The AirCurve won't power your iPhone, but the built-in pass-through slot can feed a dock cable through the bottom. Connect that dock cable to your computer or power adapter and you can sync or charge while you listen.
