The characteristic of vibration, most existing bone conduction technologies all can not really solve the problems, such as that osteoacusis leaks sound, this is because the prior art
The skeleton of frequency dependence and the reality of tissue attenuation vibration signal are compensated by big volume, big vibration signal,
That is that this method is equivalent to and drinks poison to quench thirst, and user can complain that leakage sound is serious, or since it is desired that bigger power, osteoacusis are loyal
Sub-volume weight greatly increases, and causes equipment whole excessively heavy.(5) bone conduction earphone is the system of open ears, works as user
It stays in a noisy environment, can't hear the sound transmitted in earphone at all since the opening of bone conduction earphone will lead to user
Sound.
