This creation discloses a kind of bone-conduction device, the bone-conduction device include: head fixing device, brain wave detection connect end, frequency signal generation circuit, audio device and mixer. Using seven independent bone conduction cell operations, the operation of an at least bone conduction unit is arranged in head suitable position； In the middle, the message information that bone conduction unit receives is transformed into mechanical oscillation, and by generating vibration force, seismesthesia and mechanical oscillation with a region of calvarium cortex, the otica mechanical oscillation transmitting sense of hearing can be cooperated to input brain together, as a result generate listen, position sense and other effects i.e. " the third sense of hearing ". Frequency signal generation circuit generates specific frequency signal and feeds back to mixer, mix with normal message according to eeg signal, and the variation that produced message variation out can be asserted E.E.G is made second and confirmed.本創作公開了一種骨傳導裝置，該骨傳導裝置包括：頭部固定裝置、腦電波檢測接端、頻率信號產生電路、音訊裝置以及混音器。採用七個獨立骨導單元運作，至少一骨導單元操作，設置在頭部合適位置；當中，骨導單元接收到的音訊資訊轉變成機械振動，並通過與顱頂皮層的一區域產生振動力、振動感覺和機械振動，可以配合耳骨機械振動傳遞聽覺一併輸入大腦，結果產生聽、位置感等效果即“第三聽覺”。頻率信號產生電路根據腦電波信號，產生特定的頻率信號回饋給混音器，與正常音訊混合，所產生出的音訊變化能確立為腦波的變化作第二次確認。
