Wouldn’t it be awesome if you could just hang your speakers on the walls, just like you do with calendars or movie posters? Well friends, if the following technology ever takes off, this may eventually become reality.

Developed by researchers at Taiwan-based ITRI, Flexpeakers are composed of arrays of tiny speakers that can be attached to each others to produce high-quality, paper-thin speakers of almost any sizes. And because they are lightweight and consume very little power, these speakers could be the perfect solution for use in cellphones and public advertising billboards of all kinds.

The only problem? For now, their frequency range, from 20KHz down to 500Hz, isn’t too amazing. Now if only someone could come up with a super-thin subwoofer, all our problems would be solved.
