We've seen some far-out portable speakers, but Targus is keeping it simple with the upcoming Portable Speaker Book. The folding speakers feature NXT flat-panel Balanced Radiator drivers, and can be powered by either four AAs or USB power. We've no word on pricing, but we wouldn't expect to break the bank when these hit the UK sometime this summer.

Recognize this sound? "Blip da da blip da da blip da da blip da da bliiiiiiiip." If you answered yes to any of the preceding questions, you may own an iPhone. The little bugger wreaks havoc on your average unsuspecting, unshielded desktop speaker -- and most iPod docks, as it turns out -- emitting audible blasts of interference from up to three or four feet away. Luckily, the DLO Portable Speakers for iPhone don't have that problem, since they're shielded from TDMA interference. You can power 'em off of AAA batteries or an AC adapter, and since they plug into the iPhone's headphone jack, you can use plenty of other audio sources. The speakers detach from the rotating base, and you can even use the setup as a speakerphone if you'd like. They're out now for $50.

Not likely to be your ordinary set of tin-can, iPod travel speakers, we bring you this 2.1ch setup from Princeton. Conflictingly dubbed the PSP-312IPIR2 (uh, "PSP" Princeton?), this kit appears capable of delivering what the others miss. Namely, a couple of 3W / 4Ω speakers with dedicated 6W / 4Ω subwoofer which can hopefully deliver a little thump when on the go. The bundle brings that "made for iPod" badge of whoredom and delivers a 3.5-mm jack, universal dock with remote, choice of USB / Firewire connectivity back to your PC / Mac, up to 25 hours of continuos play off 4x AAA batteries batteries, and simulated 3D sound at the touch of a button. Best of all, it folds down flat into a 421-gram / 0.93-pound slab (with remote, no batteries) for fairly easy portability. Available in black or white with plenty of that blue LED action for ¥12,800 or about $108 when they hit Japan later this month. Check that sub and folding transformation after the break.

Update: So, Made for iPod isn't the only badge these are wearing; how 'bout trying on rebadge Princeton since these have been out as the Logic3 i-Station for more than a year. Thanks to our readers for the gentle reminder.

If you just gotta have the thump only a, uh, 2 x 0.5 watt pair of USB-powered speakers can deliver then by all means, have at these from Buffalo. Dubbed the BSPL-MU09N/SV in a fit of alphabetical vomit, these bezel-attached speakers bring a 4-ohm impedance, 200Hz~12kHz frequency zone, and 3.5-mm stereo-in for excreting that laptop sound. Yours for ¥4,179 or about $36 starting late September, you know, if you're just feeling silly.

The font of gadget goodness that is Thanko just keeps on giving, with the Japanese manufacturer now trotting out its NB-mate multi-function device to make our lives a little easier. A USB 2.0 hub that doubled as a portable speaker system would have been sweet enough, but Thanko takes things even further, with the NB-mate also able act as a power source for any USB-powered device by popping in couple of rechargeable Ni-MH batteries, which themselves can be recharged by plugging the NB-mate into an AC outlet. It's the circle of life, man -- and it'll only cost you fifty bucks.
