Stretchable, Flexible, Transparent Nanotube Speakers
An anonymous reader writes "Chinese researchers have realised that a sheet of nanotubes behaves like a speaker when you send an audio current through it. The technology opens the way for a range of new versatile speaker systems. A video shows the speakers in action — some are stretched, one has even been sewn into a flag."
I wonder how long before this technology is affordable?

This is awesome! The problem with conventional speakers is the have huge difficulty dealing with subtle differences in volume. This means the tone color of recorded sound is never as interesting as real sound. It also gives problems when recording orchestras that get loud and soft. Check Beethoven's ninth symphony for an example, it starts of as soft, like a single instrument tuning, the grows into a deafening roar, whereas the contrast is not nearly as emotional and exciting on a speaker, meaning we miss out if we can't afford our own pocket-orchestra.
In addition, if you click on that link, you will hear violins. However, those violins will not sound like real violins. There is a whole spectrum of musical interest that must be flattened out to get this in a speaker.
Now, however, carbon nanotubes might be the key to unlocking giant sound in your living room. Exciting times!
Wow, I haven't been this excited about new technology since I saw a lazerdisk. And that was just because it was big and shiny.
Qxe4
To me it seems a natural fit to help "ruggedize" consumer electronics. One of the hardest things to seal on your phone is the speaker (and mic... which this probably wouldn't address in itself).
No more need for a speaker - just put the candybar up to your ear.
I used to have a sig, but I set it free and it never came back.
No matter what I try, certain articles are collapsed in the main-page view - including this one in Technology. Can someone tell me how to ensure that ALL articles are expanded?
