Targus has introduced something new for the portable speaker market called the Speaker Book. Creating a good set of portable, battery-operated speakers seems to be quite a challenge, and although we’re not sure how it sounds quite yet this one at least looks like a pretty cool solution.

The Speaker Book, like the Targus SonicPak backpack, uses the super-thin NXT Balance Radiator speaker technology and pumps out the tunes from your portable player through a standard 3.5mm jack. Also it can be powered by either three AAA batteries or from a USB connection if you want to run it from something like your notebook computer.
