The central processing unit includes being wirelessly transferred submodule, and the submodule that is wirelessly transferred is used to examine with outside brain wave
Measurement equipment is communicated.
A kind of method for exporting ears frequency difference music, as shown in Fig. 2 comprising the following steps：
S1, the music type or detected to the brain wave that the central processing unit acquisition user is selected by input module
The brain wave that equipment is sent is analyzed and the music type of the adjusted brain wave；Wherein, the music type includes
Alpha ears frequency differences music, Beta ears frequency differences music, Theta ears frequency differences music, Delta ears frequency differences music, Gamma
Ears frequency difference music etc..
S2, the central processing unit read corresponding auris dextra audio according to the music type from first audio-frequency module
Data, read corresponding left ear voice data from second audio-frequency module and corresponding background is read out of described memory module
Voice data；
S3, the central processing unit read corresponding background audio data according to the frequency difference out of described memory module；
S4, the central processing unit is to the auris dextra voice data, the left ear voice data and the background sound frequency
According to being decoded and be reduced to analog audio data；
S5, the central processing unit export the analog audio data by the output module.
Conventional audio make be through simulation sound source (such as singing of the stream of the Nature), record analog audio frequency (such as with
192k/64Bit Sampling techniques are recorded), biometrics, compression, decoding and the last several steps for being reduced to analog audio.And this reality
Recording, compression and reduction need not be sampled by applying the music output of example, it is only necessary to directly send digital audio, decoding and reduction and simulation
Three steps of audio.So as to reduce sound damage, reaction time of the brain to left and right acoustic channels frequency difference is shortened.Pair of the present embodiment
The background sound that frequency difference music can be selected with user oneself is mixed without influenceing frequency spectrum, solves double frequency music making process handle
The sound damage problem that the partial frequency spectrum of background music deletes.
The brain of the mankind can analyze the frequency of sound after the sound in receiving nature, and the sound wave of different frequency is produced
Raw different response.Ears frequency difference music is that the frequency of left and right acoustic channels is different, such as L channel 440Hz, R channel 432Hz, frequency
Poor 8Hz, brain can detect this frequency difference, and send the brain wave equal to 8Hz, and be the brain wave of the right and left brain all
Send same frequency.The auris dextra frequency of the present embodiment design is more than left ear frequency, such as 8Hz ears frequency difference music, then left
Ear 440Hz, auris dextra 432Hz.
Brain wave is some spontaneous rhythmic neural electrical activities, and its frequency variation scope is between per second 1-30 times
, four wave bands, i.e. Delta δ (1-3Hz), Theta θ (4-7Hz), Alpha α (8-13Hz), Beta β can be divided into
(14-30Hz).In addition, when awakening and being absorbed in a certain thing, a kind of frequencies of Chang Kejian Gamma γ higher compared with β ripples
Ripple, its frequency are 30~80Hz, and wave amplitude scope is indefinite；And in sleep it may also occur that the more special normal brain activity of other waveforms
Electric wave, such as hump ripple, σ ripples, λ ripples, κ-complex wave, μ ripples.
Such as the brain wave frequency in each stage of people's sleep is different.
First stage, loosen：Start to sleep, first pass around thinking relaxation state.In this stage, may persistently take out
Jerk, may be relevant with fatigue or sleeping position.
Second stage, light sleep：Into second stage, whole-body muscle further loosens, and scientist is referred to as at this stage
Light sleep, brain wave are in Alpha state.
Phase III, depth are loosened：Into the phase III, whole-body muscle depth is loosened, and brain activity reduces, and brain wave is in
Slow Theta ripples.Slow wave sleep.
Fourth stage, deep sleep：Into fourth stage, whole-body muscle loosens completely, into almost with isolation
State.There are Delta ripples in brain wave.
Deep sleep is all particularly important to the psychology and physiological health of people.Because its close phase of generation with growth hormone
Close, growth hormone can help to repair damaged tissues.This stage of deep sleep is not undergone, even if waking up can also feel exhausted.
Deep sleep fortunately strengthens memory, assist process exterior trauma.
24 hours one day, the frequency of brain wave experience was from Beta ripples in morning to evening Alpha, Theta during sleep,
The regular changes of Delta.The brain wave on normal person daytime should be Beta ripples, be Alpha ripples at night, be Theta during sleep
Ripple and Delta ripples.The reasons such as modern life rhythm anxiety, operating pressure, cause brain wave on daytime to be not reaching to Beta state,
Alpha state is not entered at night.
Thus the present embodiment is designed with different music for the different brain wave of the mankind.Such as in user's progress on daytime nothing
Essence beats coloured silk, and brain does not enter into Beta state, and user wants to obtain the good state of mind, has pressed Beta buttons, then the sound selected
Happy type is Beta ears frequency difference music；Central processing unit reads the 440Hz right sides according to the music type from the first audio-frequency module
Ear voice data, from the second audio-frequency module the left ear voice datas of 428.5Hz are read, its frequency difference is 11.5Hz, central processing unit root
Corresponding 12-25Hz beat background audio data also are read (according to left and right acoustic channels frequency difference from memory module according to 11.5Hz frequency differences
It is Alpha, Beta or Theta, selects the background music of different frequency, it is ensured that background music will not be with the frequency difference of left and right acoustic channels
Conflict)；Central processing unit is to 440Hz auris dextras voice data, the left ear voice datas of 428.5Hz and 12-25Hz beat background audios
Data are decoded, and are reduced to analog audio data, are exported analog audio data by output module and are set to the outside such as earphone
It is standby.Brain receives Beta ears frequency difference music by earphone, the brain computer of Beta state is sent, so as to reach good spiritual shape
State.
The frequency that the musical instruments of the present embodiment can improve brain wave is disorderly, effectively prevention and auxiliary treatment of insomnia, interior point
Secrete imbalance, pressure, antimigraine, anxiety, melancholy, obesity, nerve degenerative diseases chronic diseases.It can be also used for developing children's intelligence
Power and brain problem-solving ability.Ears frequency difference music is greatly increased in treatment insomnia, elimination pressure hormone, training brain
Effect.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to foregoing embodiments, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments is modified, and either which part or all technical characteristic are equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the model of various embodiments of the present invention technical scheme
Enclose, it all should cover among the claim of the present invention and the scope of specification.
