Working Principle of Bone Conduction Vibrator:

Piezoelectric Bone Conduction Vibrator, is composed by multi-layer piezoelectric ceramic sheet and a piece of metal substrate. When the excitation signal is applied to the multi-layer piezoelectric ceramic plate, the vibration plate generates vibration, and the vibration is transmitted through solid materials, such as human skull and auricle cartilage, directly to the cochlea, so as to achieve the sound transmission effect.
