How bone Conduction Bluetooth Headset works:

Under normal circumstances, sound waves are transmitted to the inner ear through two paths of air conduction and bone conduction, and then vibration is generated by the inner and outer lymph fluid of the inner ear. The spiral organ completes the process of sound sensing, and then the auditory nerve generates nerve impulse and presents to the auditory center. After comprehensive analysis of the cerebral cortex, the sound is finally "heard". Perhaps for air conduction (the path is sound wave - auricle - external auditory canal - tympanic membrane - malleus - incus - stapes - vestibular window - external, endolymph - helix - auditory nerve - auditory center), we have more or less a sense of understanding, but for bone conduction, it is somewhat confused. Perhaps for example you can understand: put your hands over your ears, talking to yourself, no matter how small the voice, we can hear what we say, this is the result of bone conduction.

There are two kinds of bone conduction, namely mobile and squeeze, which can stimulate the spiral organ to induce hearing together. The specific conduction pathway is as follows: "sound wave - skull - bone labyrinth - inner ear lymphatic fluid - spiral organ - auditory nerve - auditory center of cerebral cortex". People don't usually need their skulls to sense sound, but when lesions in the outer and middle ears block sound transmission, bone conduction can be used to compensate for hearing. Such as bone conduction hearing AIDS, bone conduction headphones, etc., is to use bone conduction to feel sound.

Most of the time, contact with the earphone is through the "air conduction", called "air conduction earphone"; The bone-conduction principle produces headphones called "bone conduction headphones."
