RICHARDSON — "Tiny" is the new "big" — at least when it comes to the
race to invent audio speakers that are invisible to the naked eye.
Scientists at the University of Texas at Dallas are working on ways to
cover your walls, TVs and computers with speakers that no one can see.
How?
By turning heat into sound.
Scientifically, it's an old phenomenon, but Mike Kozlov's new twist is
doing it through space-age materials called carbon nanotubes.
What looks like a crude experiment today could have mind-boggling
applications tomorrow, like invisible speaker "film" applied to windows
or walls.
"Speakers, you know, can be become almost invisible," Kozlov said.
"They can act as speakers in ways... in places... that normal speakers
would have no chance of working," explained Carter Haines, a UTD
undergraduate student who works on the futuristic speakers.
It's all kind of amazing, considering the basic idea is more than 130
years old.
