The frequency difference between said two audio waves is just the frequency of alpha or theta cerebroelectric waves, which can be generated after they are used for a certain time to improve cerebral functions.

Description

Audio-frequency generator and frequency divider are being induced the application that takes place aspect α and the θ brain wave

Technical field

The present invention relates to the purposes of audio-frequency generator and frequency divider, especially relate to their application in the perception of strengthening brain, memory, thinking.

Background technology

Brain is the special organ that the mankind grow up for the adaptation living necessities, and its main task is the information of gathering machine inside and outside environment, through to information Processing, makes the decision-making and the reaction that conform and help surviving.The information of external environment condition is diversified, show with different shapes such as light, sound, chemical constituent, mechanical pressure, temperature, is neuroelectric pulse through receptor cell or nerve ending with the signal transition of different-energy form, such signal of telecommunication can obtain by the measurement of electroencephalogram, the EEG signals amplitude that records is at the 50-100 microvolt, include a plurality of frequency contents in the electroencephalogram, generally be divided into four wave bands, δ ripple 1-3 time/second, when thalamus nonspecific afferent system functional defect, occur, also can occur when influenced by drug effect.The θ ripple mainly occurs when sleep state for 4-7 time/second.α ripple 8-13 time/second, occur during clear-headed and tranquillization relaxed state.β ripple 14-30 time/second, how occur during state dry putting forth energy.

These rhythm and pace of moving things and variation thereof are relevant with neural integrality as can be seen, and particularly sleep is relevant with neural regulation and control with the conversion of awakening.When sleep, in order to reduce the consumption of energy, make nerve not be given birth to and brought up breath, the irritability of cortical neuron integral body reduces, because blocked importing into of sensation, adjacent neurons synchronization trend strengthens, and has enlarged the synchronization scope, therefore the high-amplitude slow wave occurs when sound sleep, the activity characteristic of this neuron pool is adapted to dormant requirement.After the awakening, brain is in the state of receiving information, and after external information is imported into, causes active reinforcement in the brain, and different piece brain interval vies each other, and movable quick variation on space-time in the brain occurs.Present the α ripple.

Otherwise,, should guarantee that brain is in the state of a corresponding brain wave in order to create a good operation, academic environment.As best study and work environment is the state of the lax tranquillization regaining consciousness, and promptly is in the state of alpha wave.Best sleep environment is the state that nerve is is not given birth to and brought up breath, promptly is in the state of θ brain wave.State that so how to regulate and control brain makes it produce required brain wave, takes to take the tonic of nutrition cranial nerve at present, regulates brain function.Its exercising result how, and opinions vary really, unable to decide which is right, clear hardly.Now also there are indivedual inventors directly to apply the α ripple of a fixed value to brain, but can learn from Fourier transform, spectrum component is very abundant under so low frequency, in a square wave, include a lot of sine waves, therefore the error with the center rhythm and pace of moving things will be very big, and the acceptance level of everyone centering cardiac rhythm is different, can not put on whole crowd with a fixed value, and different people is fit to the alpha wave of different value.Therefore seek and can apply one to brain and have the method that irritating low frequency wave brings out required brain wave, making brain directly enter the state that required brain wave takes place is the task of top priority.

Audio-frequency generator is a kind of commonplace and facile instrument, is used to take place the interior ripple of audio range, and cranial nerve cell is had certain stimulation.If can utilize this instrument to induce α and θ brain wave take place, will be subjected to people's welcome.

Summary of the invention

The technical problem to be solved in the present invention is to utilize audio-frequency generator and frequency divider to induce fast, reliably α and θ brain wave take place.

Inducing generation α and θ brain wave is with audio-frequency generator and frequency divider series connection, at the outfan of audio-frequency generator and frequency divider, each connects an earphone, inserts in the ear, respectively import a sound wave for left ear and auris dextra, the difference on the frequency that makes 2 sound waves is the frequency of alpha wave or the frequency of θ brain wave.Regularly induce every day, and behind certain hour, every day, brain can send identical brain wave on time.

More than invention is tested on a part of human body, and result of the test is as follows:

1. enterprise staff, the woman, 30 years old, tired easily during work, energy was difficult for concentrating, mistake often takes place, used α and the θ brain wave made by the inventive method and induced generator after 15 days, the α ripple has had tangible increase, and α/β has increased by 20%, when work, can concentrate one's energy, After Hours can feel relief.

2. enterprise staff, the man, 35 years old, use α and θ brain wave to induce generator at every turn, 20 minutes, use after 20 days, measure electroencephalogram and obtain the α ripple and obviously increase, α/β has increased by 10%, feels full of vitality during work.

3. government civilian, the man 42 years old, feels that health is tired out every afternoon, nighttime sleep is very shallow, be difficult for clear-headed morning, used α and θ brain wave to induce generator afterwards, respectively used 15 minutes before working every day and before the sleep, working pre-induction alpha wave, sleep pre-induction θ brain wave, as a result every afternoon imperceptible tired out, can easily get up morning.

4. middle school student, the woman, 17 years old, the time of paying attention to the class on the classroom was long slightly, just can not be wholwe-hearted, though eyes are looked at blackboard, one's eyes are lustreless, the brain blank out, evening, brains was had dizzy spells when reviewing lessons, dysphoria, the learning efficiency is low.Used α and θ brain wave to induce generator after 30 days, α/β has increased by 60%, listens class hour energy to concentrate, and memory obviously strengthens, and feeling of fatigue has disappeared.

Facts have proved that the present invention can induce reliably α and θ brain wave take place, method is simple, practicality, instant effect.

Description of drawings

Accompanying drawing 1 is the electroencephalogram of brain under different excitatory states;

Accompanying drawing 2 is being induced the enforcement schematic diagram that the application aspect α and the θ brain wave takes place for audio-frequency generator of the present invention and frequency divider.

Specific implementation method

The range of sounds that people's ear can be heard is 30-20000Hz, resolution capability to sound is 〉=20Hz to experience the stimulation of α ripple and θ ripple in order to make big brain-capacity, as shown in Figure 2, can use audio-frequency generator 1 to add frequency divider 2, audio frequency range is transferred to the scope that can hear, and makes the frequency of left and right two ears inequality, its difference on the frequency is α ripple or θ wave frequency, i.e. (4-7,8-13Hz), be that 100Hz and auris dextra are 110Hz as left ear, the frequency difference of two sound is the frequency of alpha wave.Then two sound are sent to left earphone (3) and right earphone (4) respectively.Be subjected to the stimulation of these two ripples when brain after, because frequency difference is in 20Hz, can not dividing is two sound, think a sound, but the frequency difference that acts on brain is in the scope of α ripple or θ ripple, as applying a α ripple or θ ripple to brain separately, therefore induce a period of time after, α ripple or θ ripple can take place in brain under identical condition.So can utilize the modulator of regulating audio-frequency generator realizes, but because drift can take place in sound frequency at any time that mix up, frequency difference is changed, break away from α ripple and θ wave frequency scope, therefore in audio-frequency generator, be provided with the phase-locked loop frequency tracking circuit, there are corresponding relation in the wave amplitude of sound wave and phase place, when the frequency change of a sound wave,, make the oscillation circuit parameter change by the size of automatic adjusting wave amplitude, make the frequency of another sound wave also follow change, guarantee frequency difference precision＜1Hz.
