The technical problem that solves:
1. at first to correctly detect heart rate, and heart rate is transmitted to microcomputer chip (MCU) by discharger; Simultaneously music being carried out beat detects.Two kinds of signals are sent into microcomputer chip (MCU) and are compared, and regulate the broadcasting speed of music for microcomputer chip (MCU).
2. utilize two bio information wave producers to produce the E.E.G of two groups of difference frequencies, be mixed in the music of left and right acoustic channels for 0.5Hz～30Hz.
3. select wave, sound of the wind, brook flowing water, chirp, the bird information of the Nature such as crow, prerecord and be stored in the MP3, be mixed in the music of left and right acoustic channels for calling.
4.MP3 speed change: the broadcasting speed of MP3 require can normal speed ± 50% or bigger scope in variation, require under the prerequisite of speed change invariable tone as far as possible simultaneously, do not change the politeness of music.
5. compressed music dynamically to adapt to human needs.
6. the frequency band of compressed music: the frequency to music is carried out segment processing, with the compression frequency band.
7. use 2 (or 3) bio information wave generators to produce high frequency frequency sweep ripple, these three groups of bio information wave producers are wanted and can be worked asynchronously, and produce the plane at human body and disturb or spatial interference.The frequency sweep step-length of frequency sweep ripple is the smaller the better.To produce required audio frequency of E.E.G and the required E.E.G drive current of light emitting diode (LED) in addition.
Technical scheme: solution of the above problems of the present invention:
Basic framework: use microcomputer chip (MCU) 10 as main control unit of the present invention, cooperate keyboard 11, LCD/LED display 12, infrared remote control receiver 13, heart rate is infrared or wireless receiver 14 constitutes basic framework, other function all relies on the regulating and controlling of this framework and works.
In order to realize the beat of heart rate control music, also increased music beat detector 15: the beat of general melody claps 60～120/minute between, common people's heart rate claps 60～90/minute between, heart rate can be high to 100～180 times/minute when undesired making strenuous exercise or health for the people.So the suitable melody of should selecting speed is listened to could be more effective.
In addition, be provided with environmental detector: be respectively by critesistor and be the Temperature Detector 16 of pick off, be the luminance detection device 17 of pick off that suitable temperature and illumination can make us being absorbed in music by light sensitive diode; By mike is that the loudness detector 18 of pick off can detect current music loudness, and controls electronic potentiometer automatically by microcomputer chip (MCU) simultaneously and regulate loudness to suitable position.Facts have proved, if there is not suitable loudness, be the audition valve that can not stimulate human body.Can also instruct the user to determine correct loudness by the loudness detection.The temperature of this instrument, illumination, loudness are respectively 25 ℃, 25LX and 50dB.
Heart rate detector: in order to regulate the speed of music, adopt integrated heart rate detection discharger 70, its adopts single-chip microcomputer to receive the detected heart rate of heart rate sensor, and by infrared ray or be wirelessly sent to microcomputer chip (MCU).
Signal section: recommend through doctor, musical therapy teacher, edit at specified disease, select SoundBreeze Clubtunes, leaving the music that MP3 stores 20 li of player unit, its inside in can upgrade by USB download port 21; In addition, signal section also comprises other signal sources 22 such as CD, MD, DAT and DVD, VCD.In the time need adding wave, sound of the wind, brook flowing water, chirp, bird the information of the Nature such as crow in music, the effect sound that use in the MP3 mixes mutually with the music of CD, MD, DAT.Also can cooperate video output 23.The music current signal of music player output then is directly inputted to the music signal processing section.
Music signal processing section: the music signal of left and right acoustic channels is mixed by signal mixer 30, dynamic range by dynamic compressor 31 compressed music, usually the sentient initial current of people is about 1mA, and maximum tolerant electric current only differs 50 times about 50mA.The dynamic range of traditional music is about 90dB, and promptly the size differences maximum of amplitude can reach more than 10000 times, and people's ear can be accepted this dynamic range, but human body can not be accepted so big dynamic range.If undressed music information is directly imported human body: can cause human body numbness when the petty action attitude, can't stand in the time of greatly dynamically.So must dynamically compressing to music to adapt to the needs of human body.For example dynamic range compression is about 100 times to 40dB, then the dynamic compression amount reaches 100 times, thereby makes the music current that enters human body can adapt to the tolerance range of human body, finally exports practical whole tone music signal.
How could the happy information of whole tone be imported human body? the frequency model of music is 20～20000Hz, and low-and high-frequency differs 1000 times! Tissue has electrology characteristic, and the impedance between the skin is equivalent to the value in parallel of resistance (body fluid characteristic) and electric capacity (cell membrane characteristic).And the impedance Xc=1/2 π fc that electric capacity produces, it is inversely proportional to the frequency of tone currents, and obviously tissue is 1000 times of music high frequency to the capacitive reactance of music low frequency, even the scope of compression frequency band to 50～10000Hz just still differs 200 times! The effect of comprehensive resistance capacitance, the comparable low frequency electricity of intermediate frequency electricity total current electric current is big approximately 160 times.This is that the people is intolerable.
Music with a certain frequency for example 250Hz (needing) by physical therapy, health care be part-frequency point, be divided into high band and low-frequency range, after the segmentation, the frequency range of each section is all little, low-frequency range is 20～250Hz, only differs 12.5 times.Adopt synthetic mode then, use the low frequency modulations high frequency, high frequency is included in the envelope of low frequency, finally realized the happy importing of whole tone human body, and feeling of human body is gentle comfortable.
For the whole tone pleasure is divided into low frequency and HFS, so adopt low pass filter 33, high pass filter 34 to separate.The input of manipulator then selects a switch 36 to finish the selection of multiple signal by four, arrives amplitude modulator 37 at last and produces modulation, and the modulating wave after the modulation is sent to power amplifier after being regulated by electronic potentiometer 38.
