We've already heard first-hand how Yamaha can make surround sound emerge from a single soundbar, and now the outfit's wowing again here at CEATEC. It's latest aural innovation was tucked quietly away within its booth, disguised as an advertorial for the show itself. Essentially, the banner you're peering at above is a one millimeter thick speaker that's made from cloth, and it definitely has the potential to revolution billboards and possibly even portable media devices. As you can clearly hear in the video just past the break, the flat sound waves emitted from the cloth cannot be heard unless you're standing directly in front of it; even separate audio files playing back just a few feet away didn't overlap with what we heard coming directly at us. There's no telling if Yamaha will ever take this public, but if it does, there are about forty billion ad agencies in the greater New York area that would like to speak to it.
