It transmits sound waves through human skull, bone labyrinth, lymphatic transmission of inner ear, spiral apparatus, auditory nerve and auditory center. Compared with the classical sound transmission method which generates sound waves through vibration membrane, bone conduction eliminates many steps of sound wave transmission, achieves clear sound restoration in noisy environment, and the sound wave does not affect others because it diffuses in the air. Bone conduction technology is divided into bone conduction loudspeaker technology and bo…
