骨传导原理：
Principles of bone conduction:
骨传导直达大脑听觉神经 Sound directly conducted to the auditory nerve of the brain
through bone 空气传导 Aerial conduction 外耳道External auditory canal 耳膜
Eardrum 内耳道 Internal auditory canal 耳蜗 Cochlea 大脑听觉神经 Auditory
nerve of brain 骨传导 Bone conduction 空气传导 Aerial conduction
我们听到的大部分声音，都是声波经过空气到达耳膜，然后声波使耳膜发生震动进而将声音
传至内耳道；
Most of the sound we hear is the result of sound waves passing through our
eardrum to make it vibrate so that the sound waves can be conducted to the internal
auditory canal.
另一种方式是，声波通过骨头震动直接传至内耳而不经过耳膜，这也是人们听到自己声音的
