JiaWeiHua is the leading custom bone conduction headphone manufacturer in China, offers custom bone conduction headphones services for customers. So what is the principle of bone conduction headphones? JiaWeiHua will explain to everyone.

Under normal circumstances, sound waves are transmitted to the inner ear through two paths of air conduction and bone conduction, and then the inner and perilymph fluids of the inner ear produce vibrations. The spiral organ completes the sound process, and then the auditory nerve generates nerve impulses, which are presented to the auditory center and the brain After a comprehensive analysis of the cortex, the sound is finally "heard". Perhaps for air conduction (the path is sound waves-auricle-external auditory canal-tympanic membrane-malleus-incus-stapes-vestibular window-external and endolymph-spiral organ-auditory nerve-auditory center), we have more or less some Perceptual knowledge, but a bit incomprehensible to bone conduction. Perhaps you will understand by giving an example: cover your ears with your hands and talk to yourself, no matter how small the sound is, we can hear what we say. This is the result of bone conduction.

There are two ways of bone conduction: mobile and squeeze. The two synergistically stimulate the screw to cause hearing. The specific conduction path is: "sound wave-skull-bone labyrinth-inner ear lymph-screw-auditory nerve-cerebral cortex auditory center ". Usually, people do not need to use their skills to feel the sound. However, when the pathology of the outer and middle ear hinders the transmission of sound waves, bone conduction can be used to compensate for hearing. For example, bone conduction hearing aids, bone conduction earphones, etc., use bone conduction to feel sound.

In most cases, the earphones that come into contact are through "air conduction", which is called "air conduction headphones"; and earphones produced according to the principle of bone conduction call "bone conduction earphone".
