Description
Technical field
The present invention relates to the brain wave inductive technology, mainly be a kind of method and apparatus that produces biauricular wave difference, thereby induce brain wave.
Background technology
People's brain not only can the control person thinking and behavior, and be control people's the emotion and the highest maincenter of vegetative nerve function.
Find that in research in people's life process, whole machine body particularly whole variations of nervous system generation can both be reflected on the electroencephalogram to brain wave.The achievement of modern Study on brain electrical activity shows that different people has different brain wave rhythms under different situations, but regular following.In general, brain electrical acti has a dominant frequency, is exactly the most outstanding and tangible rhythm and pace of moving things in record, also is brain wave " the background rhythm and pace of moving things ", and classical brain wave rhythm and pace of moving things wave band is as follows:
δ wave band:＜4Hz (cycle per second)
θ wave band: 4～8Hz
α wave band: 8～13Hz
Beta band:＞13Hz
Under the situation of no any environmental stimuli and drug influence, normal adult when clear-headed brain electrical acti generally at the α wave band, be 8.5～12.5Hz, between or be mixed with below a small amount of (15%) 14～21Hz β ripple and 4～7Hz θ ripple by a narrow margin, and when attention is concentrated or done mental arithmetic, alpha rhythm will disappear and be replaced by beta response, also have to occur the higher theta rhythm of wave amplitude when being reported in ergasia.Having 6% normal person to show with the β ripple is the electroencephalogram of basilic rhythm.
The application of present stage about the Study on brain electrical activity achievement mainly contains:
(1) electroencephalogram and brain electrical activity mapping etc. can objectively show human nerve visually
The various functional statuss of system have played more and more important effect to the diagnosis and the treatment of nervous system disease and other relevant disease.
(2) principle of utilizing biological physiology to feed back, adopt electromagnetic field, magnetic field, acousto-optic stimulation, electric current directly to import methods such as human body and pulsating direct current electric field, reverse energization and induce human body, the brain electrical acti that makes the people is to normal and healthy and helpful direction synchronization, in order to regulate and to improve the emotion and the state of human body, improve life and quality of life.
Method (2) needs expensive equipment to realize usually, is not easy to people's daily use.In United States Patent (USP) " US5135468 ", described and a kind ofly heard different frequency by the ears that make the people, utilize resonance principle (to comprise phase place, amplitude of vibration, the factors such as frequency) induce brain wave that the method and apparatus of resonance takes place, its method is also referred to as the biauricular wave difference principle, and the body and mind function that brain wave comes the mediator is regulated in this patented method utilization.
Two brain synchro-resonance music CD video discs having occurred on the market now, is to cooperate E.E.G theory and biauricular wave difference principle and two brain theoretical synchronously, the CD video disc that combines with multiple audio (promptly adopt certain song and be equipped with the single-tone beat of particular rhythm).The CD video disc recording process of this kind method is comparatively complicated, only limits to the application of some specific occasion at present, and owing to will use the CD video disc of specific recording, can not utilize the content of existing video disc or tape to emit the sound wave with biauricular wave difference.
Summary of the invention
The object of the present invention is to provide a kind of method and apparatus that produces biauricular wave difference, can use existing tape, CD etc. to play the biauricular wave difference sound wave, and be convenient to people's daily use.
The technical solution adopted in the present invention is:

Implement the device of the generation biauricular wave difference of said method, include audio player and earphone, it is characterized in that, between audio player and earphone, also be in series with the frequency conversion unit that to do frequency-conversion processing to the left and right acoustic channels of audio signal.
Additional technical feature is as follows:
The device of described generation biauricular wave difference is characterized in that, it is poor that described frequency conversion unit can be regulated the audio frequency of left and right acoustic channels, and the audio frequency difference that makes left and right acoustic channels is in 0～20Hz scope.
The device of described generation biauricular wave difference is characterized in that, can control frequency conversion unit at the controller of player inside, and the audio-frequency information that makes storage is through the frequency transformation of hardware circuit left and right acoustic channels or through exporting after the software frequency-conversion processing.
The device of described generation biauricular wave difference is characterized in that, the earphone that uses during broadcast is the bone-conduction speaker earphone.
The device of described generation biauricular wave difference is characterized in that, does not do the left and right acoustic channels audio signal of frequency-conversion processing at the outfan of audio player in addition and exports, and constitutes the output of 4 channel audio signal with the audio signal of passing through frequency-conversion processing.
The device of described generation biauricular wave difference is characterized in that, the mode that left and right acoustic channels output can frequency multiplication is exported.
Above-mentioned device with generation biauricular wave difference of 4 channel audio signal output is characterized in that, has 1 pair in 4 channel audio signal of outfan output at least by the broadcast of bone-conduction speaker earphone.
The invention has the beneficial effects as follows:, can make left and right acoustic channels produce specific difference on the frequency between 0～20Hz, thereby induce the brain wave of user to resonate by in existing player, increasing frequency conversion unit.The present invention can use existing player to transform or install additional frequency conversion unit, plays existing common tape, CD waits and realizes the biauricular wave difference effect, make simple, easy to use, be suitable for popular daily use.
