What's the difference between Bone conduction headphones and normal headphones
Bone conduction is a way of conducting sound by sending the sound into a different frequency of mechanical vibration. Sent through the human skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve and auditory center to transmit sound waves. In contrast to the classical sound transmission of sound waves through the diaphragm, the bone conduction eliminates many acoustic transmission steps to achieve a clear sound reduction in a noisy environment, and the sound waves won't affect others.
When we eat a biscuit, we can hear the sound of biscuits broken because the vibration through our teeth and skulls to our inner ear. In the 18th century, the principle of bone conduction helped the great beloved deaf composer Beethoven to hear the wonderful music. Beethoven tried a technique invented by Giovanni Phillipo, England. Where he could hear the music from the jaw bones with a stick connected to the piano. This was actually the early beginning application of the bone conduction principle.
Bone conduction technology is mainly used for military, police professional headphones. Also in hearing aids, sports headphones and other fields.
