When the bone conduction headphone works, it converts the sound signal into mechanical vibration by the sound unit and drives the skull to vibrate at the same frequency, allowing the sound to reach the cochlea of the middle ear and inner ear. Finally, we can hear the sound. In the process of sound transmission, they directly bypass the ear canal and eardrum to reach the inner ear, taking a shortcut. Just because it takes a shortcut, it reduces the damage to the ear canal and eardrum, making it the healthiest headphone.
Most of us have been exposed to bone conduction in our daily life. Put your ears close to the ground, and you can hear the footsteps of “tap, tap, tap” through vibration; cover your ears, and you can still hear yourself mumbling, which is a natural phenomenon of bone conduction.
What are the disadvantages of bone conduction headphones?
While bone conduction headphones are popular, they’re not perfect. They also have some disadvantages, summed up in three:
Disadvantage 1 : sound quality
Because of the design characteristics of bone conduction headphones, their anti-interference effect is not ideal when wearing them for shopping, subway, car and other noisy environments. And the sound quality is not as good as traditional headphones, because they transmit sound through the skin, skull and then to the ear ossicles, so the degree of music reproduction is not as good as traditional in-ear headphones.
Disadvantage 2 : sound leakage
