Fresh from the streets of Japan, the Yorozu Audio Sound Revolution kit lets you transform just about anything into a speaker.

Simply mount the Yorozu’s vibrating sonic transducer wherever you want it, and it’ll turn the surface into a conductive sound system. While the kit includes a cardboard milk carton that you can use for starters, pretty much any piece of cardboard, a window, a plastic water bottle or even a white board will work. While the speaker’s 1-watt amplifier (2-watt peak) won’t blow anyone’s eardrums, you’re probably buying one of these for the curiosity of it, not for the volume.

I couldn’t find a video of the Yorozu in action, but I did manage to dig up this clip of an OEM version of the same technology, which shows off how it works.

And if you don’t live in Japan, no worries. The guys over at the Japan Trend Shop have been kind enough to start shipping these around the globe for all of us to enjoy. ($89 USD).

At just 50mm x 50mm x 60mm (about 2.36″ x 2.36″ x 1.96″) , the portable VIBRO Sounder is designed for use with a laptop or mobile audio device, and will send sound through any surface that it’s in close proximity to. The maker claims that it will work with glass, wood, stone or other hard wall surfaces to create sound. The speaker features a 20 Watt (RMS) amplifier and a remote control.

I’m not sure how different the technology is from the old Soundbug, released a few years back to underwhelming reviews.
