Skull Resonator

Bateryless, solid state, invisible headphones.

  [vote for,

The Idea is to implant quirurgically two small and thin metal disks in the skull near the ears, and fix them in the bone, under skin and muscles.

A powerful magnet might make them resonate, thus obtaining sound. Music sistems might use magnetos instead of speakers, pointed to where usually the head of the listener is.

Lots of tech and medical holes to fill in this one, but might be interesting to hear music in a silent room.

       I think this is baked. I think they can use EM waves to resonate your eardrum directly thru your skull. Or I might have just been really high and imagined that...

       hmmm interesting

       I wear hearing aids and have a device connected to the TV that transmits the sound via a loop antenna so that I hear the sound in me haid even when the room is silent. Great for late night movies.

       There is a guy producing speakers that directly stimulate the hairs /receptors in the ear w/o vibrating the intervening air molecules. <Erm,> I think I read it in The New York Times Magazine a couple a years ago. He would aim the speakers at someone walking by in the mall and only that person could hear the sound and it sounded as if was being played right behind his head. It has been a couple of years so the details are fuzzy; the idea is both scary and attractive at the same time - wrt ads, spam and so on.
