I heard about sound via bone conduction and was hooked, but I can't find any information anywhere on the web. Answered

Bone conduction is awesome, but there aren't any instructables. A little help please?


The oversized Hallmark sound birthday cards have a "speaker" that uses the whole card to make the sound. Put that speaker against your head ahd you have a bone conduction device.

     No offense meant, but none of these answers aren't very helpful at all.

     As to frollard's answer:
          I learned about Beethoven's use of dowels in my senior year of highschool (laid the foundation of my fascination), and bone conduction is mainly used in cochlear implants and  bluetooth headsets(didn't know it was used for noise cancellation yet). I have also found articles mentioning its use in headphones (especially those worn when diving), the rare odd cellphone, wristwatch phone, mp3 player, and military headsets.
     As to cyberpageman's answer:
          I've been doing so for the past 2-3 months.
     As to NachoMahma's answer:
          I also came across the BoneFone article in my search. The article itself was written in 1979.

     So, since it seems that my question wasn't specific enough, I'll try to rectify my mistake.
     Does anyone know how to actually make a bone conduction headset, apply bone conduction to any audio-based project, or modify/hack speakers/headphones to use bone conduction and if so, why haven't they written up an instructable?

Beethoven was near deaf after <insert unknown infection here>...he used a hardwood dowel held between his teeth touched against the piano to better hear the vibrations as he wrote a few symphonies.

cochlear implants work on a similar theory - some physically shake the inner ear bones to reproduce sound for a deaf person.

Also, as nacho links - the jabra jawbone bluetooth headset uses bone conduction to help calculate and eliminate background noise.
