Bone conduction:-
Bone conduction is the conduction of sound to the inner ear through the bones of the skull. Bone conduction transmission can be used with individuals with normal or impaired hearing.
Overview:-
Bone Conduction
Bone conduction audio safely transmits sound vibrations through the upper cheek bones of the face to the cochlea of the inner ear. Unlike traditional earphones these are not placed over or in your ears. Instead, they are positioned along the upper cheek bone directly in front of the ears. And because they do not cover or impede the ears, you can hear your surroundings while enjoying great-sounding music while exercising, including bicycling or jogging outdoors.

Some people have hearing aids then this conduction technology is became a helpful thing for them.
Bone conduction products are usually categorized into three groups:Ordinary products, such as hands-free headsets or headphones
Bone-anchored hearing aids and assistive listening devices
Specialized communication products (e.g. for underwater or high-noise environments)
One example of bone coduction is The Google Glass device.
this technology is sends the signals as lightly vibrations under or above our ears.these signals are send to our mind as sound signals directly without use of diafram. this is conduct the signal in our bones so this is called bone conduction Technology
now a days many items are available in the market to use this technology.....
