Paper Flexpeaker could change the way you perceive posters

Tim Stevens

Paper speakers go a long way back, but now finally seem close to making appearances in the real world. A few weeks ago it was researchers at the University of Warwick showing off their wispy wares, and now Taiwan's Industrial Technology Research Institute is talking up its thin tweeters, called Flexpeaker. The initial goal is for 8.5-inch by 11-inch sheets that cost about $20, but the hope is to produce whole rolls of the stuff in the not too distant future, which will then be liberally applied to the exteriors of movie theaters, the interiors of automobiles, and the sides of the thinnest of thin-panel TVs. An effective range of 500Hz to 20KHz leaves an awful lot of lower frequencies lacking, but perhaps someone will invent a paper subwoofer one of these days.
