Expands Like An Accordian

This Mini Speaker is about the size of a hockey puck, and probably sounds about like most of the other small speakers you might plug into your cell phone or iPod. But wait just a minute. This one expands like an accordion, creating a chamber for sound to resonate and giving these diminutive drivers a chance to move some air, pumping out a respectable amount of bass.
We have our doubts, though. The rechargeable unit cranks out 2.4W for 6-8 hours, which isn’t a whole lot of power no matter how big that resonating chamber is. Still, this $31 nugget of sound is small enough to fit in the most cramped compartments, practically begging you to take it along, acting as a willing accomplice to your sudden urge to bust a move.
