Bone conduction vibrator {BONE CONDUCT VIBRATING DEVICE}

The present invention relates to a bone conduction vibration device for stimulating the auditory nerve through bone conduction to directly listen to sound by vibrating the head bone forming the skull, and more particularly, to sound source data stored in a memory. Data that promotes the generation of functional EEG, such as alpha and beta waves, are mixed, and the magnet conduction unit inserts the bone conduction unit into the body so that the vibration for bone conduction of the bone conduction unit is not affected by the body and is applied to the head bone.
