Description
Technical field
The present invention relates to a kind of simulator, relate in particular to a kind of brain wave simulator that is used to simulate brain wave signal.
Background technology
Everyone, every day, each second, no matter what is being done, even in bed, our brain all can produce " current impulse " every now and then, and these are referred to as " E.E.G " by the electric current that brain produced.
E.E.G divides according to frequency, is broadly divided into four big classes: β ripple (consciousness), α ripple (consciousness and subconscious bridge), θ ripple (subconsciousness) and δ ripple (unconscious), the combination of these consciousness has formed the inside and outside in behavior and performance in study of a people.
Therefore, how to utilize E.E.G, cooperate E.E.G to change the inside and outside of a people, promptly become the target of pursuit in behavior and enhancement performance in study.
Summary of the invention
Therefore purpose of the present invention is exactly that a kind of portable device of simulating E.E.G is being provided, and by sending corresponding specific brain regions wave frequency, changes the inside and outside in behavior and enhancement performance in study of a people.
For reaching above-mentioned purpose, the invention provides a kind of brain wave simulator, be arranged in the portable device, wherein this portable device can receive first acoustical signal, this brain wave simulator comprises at least: arithmetical unit, become second sound signal in order to this first acoustical signal is carried out fourier transform (Fourier Transform); Frequency modulator receives this second sound signal, and this second sound signal frequency superposeed or reduce characteristic frequency becomes the 3rd acoustical signal, wherein the corresponding frequency of brain wave of this characteristic frequency; First speaker is in order to export this second sound signal; And second speaker, in order to export the 3rd acoustical signal.
According to this, the present invention utilizes portable device to simulate the brain frequency of brain wave, allows user remain on joyful mood when using portable device.

The specific embodiment
E.E.G divides according to frequency, is broadly divided into four big classes: β ripple (consciousness), α ripple (consciousness and subconscious bridge), θ ripple (subconsciousness) and δ ripple (unconscious).Following table is the respective frequencies of each E.E.G, and individual inside and outside in behavior and in study performance relatively:
β ripple (12~38 hertz) | α ripple (8~12 hertz) |
The ripple that belongs to " consciousness aspect ".The source of intelligence.The ripple that needs when logic thinking, calculating, reasoning.When clear-headed.Attention concentrates on external sense organ in the world.Want hardy to deal with problems.Pressure is very big, psychology is uncomfortable, nervous, worry, uneasy. | It is the bridge between " consciousness and subconsciousness aspect ".Do daydreaming.The source physical relaxation of imaginative power, absent-minded, open ambition. |
θ ripple (4~8 hertz) | δ ripple (0.5~4 hertz) |
The ripple that belongs to " subconsciousness aspect ".There are memory, consciousness and emotion.Influence attitude, expectation, conviction, behavior.The source of creativity and inspiration.Sound sleep is dreamed, degree of depth when meditation.Soul awareness, individual experience are strong, have a strong temperament. | The ripple that belongs to " unconscious aspect ".Needed when being the sleep that regains one's strength.The source of intuitive and the sixth sense.The radar fence of consciousness. |
The present invention is by sending corresponding specific brain regions wave frequency, coming and the brain synchronous operation, brain is bestowed certain stimulation.In one embodiment, the present invention sees through the modulation sound wave, sends specific frequency, comes to produce resonance effect with corresponding E.E.G.
Fig. 1 has illustrated the skeleton diagram according to the brain wave simulator 100 of a preferred embodiment of the present invention.Wherein this brain wave simulator 100 can be applicable in any device that sends the sound.In a preferred embodiment, this brain wave simulator 100 is to be installed in the mobile device, for example in the mobile phone, can carry out synchronous modulation at caller's the sound of replying, and export the sound of replying of corresponding specific E.E.G, the emotion of remote-effects user.Below will application of the present invention be described with the embodiment that the present invention is applied to portable device.
For example, suppose that this caller replys sound 110 by after carrying out fast fourier transform arithmetical unit 101, its frequency is 200 hertz, and first speaker 103 was output as 200 hertz caller and replied sound this moment.If institute's mimic E.E.G of desire is 20 hertz a β ripple, frequency modulator 102 promptly can be replied 200 hertz of callers that received acoustic frequency and superposeed or reduce 20 hertz this moment.If superpose 20 hertz, then second speaker 104 is output as 220 hertz caller and replys sound.Because people's ear can't be distinguished the close but different sound of frequency, as 200 hertz and 220 hertz.When but two sound send simultaneously, what heard is promptly 210 hertz of the meansigma methodss of two sound, hears that simultaneously this sound has 20 strong and weak variations that rise and fall each second, just is the poor of frequency, this phenomenon is " beat frequency " (beat), equals the mimic 20 hertz of E.E.Gs of institute's desire.According to this, user can remain under the mood good state when receiving calls.
In another embodiment, when this portable device is non-when being used in telephone answering, user also can be used as music player with it, as shown in Figure 2, play the music of a corresponding specific brain regions wave frequency, the signal that imports arithmetical unit 101 into is another acoustical signal 112 that non-caller replys sound 110 this moment, for example, and a music signal that is sent for portable device audio-video system 120 thus.In this embodiment, this portable device also can comprise selectivity user interface 105, provides user to select the mimic specific brain regions wave frequency of desire, i.e. β ripple (consciousness), α ripple (consciousness and subconscious bridge), θ ripple (subconsciousness) or δ ripple (unconscious).When if to select mimic E.E.G be 20 hertz β ripple, at first can carry out fourier transform with the acoustical signal 112 that receives arithmetical unit 101, make this acoustical signal 112 transfer frequency domain to and by the output of first speaker 103 by time domain, frequency modulator 102 then can with transfer to acoustical signal 112 behind the frequency domain superpose or reduce 20 hertz after by 104 outputs of second speaker.According to this, when this portable device is non-when being used in telephone answering, user also can be used as music player with it, plays the music of a corresponding specific brain regions wave frequency.
In addition, in another embodiment, also can not use twin loudspeaker, only use a speaker to simulate the specific brain regions wave frequency, when for example user is selected the β ripple of 20 hertz of simulations by user interface 105, this moment, the portable device audio-video system sent 20 hertz acoustical signal, and was exported by first speaker 103 by carrying out fourier transform arithmetical unit 101.Though people's ear can't be heard this low frequency signal of 20 hertz, can with the brain synchronous operation, brain is bestowed certain stimulation.
In another embodiment, also can use microwave to simulate the specific brain regions wave frequency, for example, in the time of in the conversation of GSM800 system, if during the β ripple that the desire simulation is 20 hertz, can utilize radio circuit that 800 hertz microwave is superposeed or reduce 20 hertz and, produce the mimic 20 hertz of β ripples of institute's desire by antenna output.
Comprehensive above-mentioned institute says, utilize portable device to simulate the brain E.E.G as the convenience of electric wave and acoustic wave source, and and then the user that superposes out in addition of the microwave signal when sound wave when mobile phone communication, will talk the time or conversation feel to loosen or happy E.E.G, allow user remain on joyful mood.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, the person of ordinary skill in the field, without departing from the spirit and scope of the present invention; when can doing various changes and retouching, so protection scope of the present invention is when being as the criterion with claim.
