From last week's Consumer Electronics Show (CES) here is an awesome speaker. ClearView Audio CLIO is a clear acrylic speaker which pushes sound through the side of the device instead of the rear, like traditional cone speakers.
Edge Motion-driven speakers actuate a thin membrane along the side
in a manner that creates an extremely efficient, piston-like motion
in front. The resultant speaker system is thin and lightweight with
the ability to produce a rich, full sound across the audio range.
