Inflatable Loudspeakers
fm6 sent in an article running at New Scientist talking about new technology that allows Inflatable Loud Speakers. The technology is apparently patented and there's not a lot of technical details, but I have to say the concept amuses me. And I somehow doubt that this technology will ever be used in high fidelity home systems.
I don't believe it for a minute.
Distortion down to 'unheard of low levels'? Hype city. There is absolutely no plausible mechanism to support this claim. As for transdcuer shapes, such as tetrahedral, it's almost completely irrelevant as far as sound quality goes.
Loudspeakers don't have a limited lifetime because of corrosion. It's usually fatigue of the constituent materials, of which an inflatable plastic would certainly be about the worst.
These might be a good gimmick, but nothing more. I think their egos need a bit of deflating.
They're apparently using NXT flat panel techniques. No wonder this is so full of mindless hype.
