What are the advantages of bone conduction earphone?
Recently, the earphone industry is quietly upgrading. Bone conduction earphones are widely used. There are also many users who are unfamiliar with bone conduction earphones. Let's introduce the advantages of bone conduction earphones.
1) Bone conduction loudspeaker technology earphone:
When wearing and using, both ears are opened and the ears are not blocked, which solves the discomfort of wearing in ear earphones;
Bone conduction earphones avoid a series of health and health problems caused by sweating in the ear when wearing earphones. Therefore, bone conduction loudspeaker earphone is very suitable for sports use.
Open ears also ensure the possibility of headphones in dangerous situations. Open both ears, use headphones can also pay attention to the changes in the surrounding environment, more safe to use.
(2) Bone conduction microphone technology headset:
Low sound loss due to close range. It can also let the other party clearly know the instructions expressed when the volume is very small, which is mainly used in the military field.
What is the working principle of bone conduction earphone?
Under normal circumstances, sound waves are transmitted to the inner ear through air conduction and bone conduction, and then vibration is generated by the internal and external lymph of the inner ear. The spiral instrument completes the sound sensing process. Then, the auditory nerve generates nerve impulses and presents them to the auditory center. After comprehensive analysis of the cerebral cortex, the sound is finally "heard". Perhaps we still have more or less some perceptual knowledge about air conduction, but we have no idea about bone conduction. Perhaps you can see, for example, that by covering our ears with our hands and talking to ourselves, we can hear what we say no matter how small the sound is. This is the result of bone conduction.
There are two ways of bone conduction: moving and squeezing. They can stimulate the spiral organ to cause hearing. The specific conduction pathway is "sound wave skull bone labyrinth inner ear lymph spiral organ auditory nerve cerebral cortex auditory center". Usually people don't need to use their own skull to feel sound, but when the external and middle ear lesions hinder sound transmission, bone conduction can be used to compensate for hearing. Such as bone conduction hearing aids, bone conduction earphones and so on, is to use bone conduction to feel sound.
Most of the time, the earphones contacted are through "air conduction", which is called "air conduction earphone"; while the earphone produced by bone conduction principle calls it "bone conduction earphone".
