Turn Your Head Into Speakers 167

Posted by CmdrTaco from the that-just-doesn't-seem-safe dept.
Roland Piquepaille writes "A small company based in Iowa has developed products made with a "smart" metal that can turn your walls or your head into speakers. "Last August, Etrema -- an innovative technology firm nestled in the cornfields of Ames, Iowa -- started selling those chrome discs for $1,500 a pair. Called Whispering Windows, they can turn any wall, window, or drab conference table into a speaker." The author tried the technology, and even if she needed a full bottle of Tylenol after usage, said "it's not every day that your head serves as a piece of stereo equipment." This overview tells you more about this "magic" metal, the Terfenol, which is a combination of terbium and dysprosium. The article also says that we can soon expect pirated versions of Terfenol coming from China."

      This is clearly the best technology ever developed, because it can close the analog hole. We can implant two speakers, one for each ear, just inside the skull. Each speaker will have a DAC and a decryptor chip, and a secure digital pathway leading out the ear canal. The pathway will block the ear canal to restrict unauthorized listening. The speakers will connect to a wearable Microsoft Music Center device, which will manage the user's listening rights. Later versions might include a microphone, so that the user can listen to sounds in the environment, after a short delay to ensure they aren't watermarked.

      Although some cyber-terrorists may consider this a drastic method, it's the only way to protect the content industries, which are vital to America's economy, from rampant piracy and theft. Therefore, I'm proposing legislation requiring these devices to be implanted in each child before they turn two. Please join my crusade of consumer protection and write your congressman today!

They are generally used as replacements for voice coils [theproductfinder.com] and for the same reason. If you want to actuate your domestic structure, you can use a big one [beikimco.com] and keep it cool with LN2.

    These materials are far too old to be covered by existing patents, so they're fabricated all over the world. Indeed, chinese manufacturers are in production [txre.net].

    • " But that's not the biggest problem. For while Etrema currently holds a monopoly on the world's smartest metal, its executives predict that within about seven years competitors will have figured out a way to make Terfenol more cheaply--or worse, to manufacture an even smarter metal. (Etrema's scientists are already hard at work developing Terfenol's successor.)"
    Without any fear of competitors, the rate of research would slow down. But because there are wolves at the door, the company will be more productive and innovative. And while it might not be this company that ultimately scores the money jackpot, humans in general will likely be better off through the enhanced development speed (speakers aren't the only application - it appears to have important ones as well).

  • But if scientists from China discover how to manufacture Terfenol -- Etrema's Snodgrass says that three Chinese companies have already started making pirated versions -- the metal's still-fragile reputation could be harmed by the cheaper, imported version.

    Heh, yeah, that's the big risk to the American manufacturer---the danger to "the metal's still-fragile reputation". Snodgrass is not at all concerned by the fact that they are about to be drastically undersold by companies with better access to the r

  • ...just let me say that this is just another reason why we're actually a cool state, no matter what stereotypical ideas you might have about us. I mean, who else would do this sort of thing if not some nuts from the heartland?

    Now, on to making our heads into bongs...
  • than ever before. At least at present the skull vibration is a peripheral aspect of the sound perception. The skull actually protects the soft tissue freom the external vibrations.

    Now we are going to make the skull the primary source of some of this sound and directly hit the brain.

    Why do we think this is a good idea. I would be concerned about a punch-drunk generation degenerating into parkinsons dementia before they are 30 and on autopsy having brains that look like they had been in way too many figh
