Snorkel Earphones
Here’s yet another example of bone conduction for new transmitting sound in new ways. Conducting sound through solids (or liquids, for that matter) is especially useful when you are either in the water, or around lots of large solid objects. Things like the water in the pool and the walls around you can become speakers with the right piezo elements vibrating them as if they were a huge speaker.
We are seeing the first steps in this direction nowadays through bone conduction technology, which uses a physical speaker that vibrates the bones in your body, sending crystal clear sound to your inner ear, bypassing any noise around you like loud restaurants or running machinery.
This particular product incorporates that technology into a snorkel, letting swimmers hear and communicate much more effectively http://gizmodo.com/gadgets/water/snorkel-transmitterreceiver-for-train ing-squads-of-navy-seals-or-water-polo-teams-324997.php
