You can use a 9V battery powered amplifier with a loop around your neck to make a tiny permanent magnet placed in your ear canal vibrate against your ear drum.

It doesn't generate hi-fi sound, but speech is remarkably clear. Great for magic tricks. Or cheating at exams I suppose.
- hrimfaxi 9mo agoHas this actually been done before? It sounds fascinating. I have seen accounts of people embedding tiny magnets in their hands but not their ears.
- vermilingua 9mo agoI believe “permanent magnet” here refers to an object permanently magnetised, not a magnet permanently embedded in the ear canal.
- Luc 9mo agoNot embedded, just dropped into your ear canal. I bought it maybe 15 years ago on eBay, so it's nothing new.
- blueflow 9mo agoDare to tell what you used it for? Or would you risk loosing some degree or something if you speak about it?
- EvanAnderson 9mo agoThat's really cool, but the idea of sticking a magnet inside my ear gives me the willies. >shudder<
- superxpro12 9mo agoI think the copper ring around your neck a.la Will Smith in Wild Wild West may clue in the test proctor to some suspicious activities
- Luc 9mo agoIt was very thin, sewed into a 'wife beater' undershirt. You wouldn't notice it even if you're looking at it. In fact I'm pretty sure it was sold for the purpose of cheating on exams.
