A bone conduction device and method. The bone conduction device comprises: a head fixing device (19), brain wave detection connecting ends (17), a frequency signal generation circuit (27), an audio device (20) and an audio mixer (22). Seven independent bone conduction units (101-107) are adopted for operation, and at least one bone conduction unit operates and is arranged at an appropriate position of a head. Audio information received by the bone conduction unit (10) is converted into mechanical vibration, vibration force, vibration sensation and mechanical vibration are generated through an area of a calvarium cortex and input into a brain together with ear bone mechanical vibration hearing transfer, and effects of hearing, sense of position and the like, namely, the third hearing, are generated. The frequency signal generation circuit (27) generates specific frequency signals according to brain wave signals and feeds the signals back to the audio mixer (22). The signals are mixed with normal audio, and generated audio change can be determined as brain wave change for secondary confirmation.
