Embodiment
As shown in Figure 1, a kind of music controls electrotherapy rssi circuit, including player, power amplification circuit, photoelectric coupled circuit,
Charge and discharge circuit, microcontroller and impulse output circuit, power amplification circuit, photoelectric coupled circuit and charge and discharge circuit according to
The port ADC of secondary electrical connection, charge and discharge circuit and microcontroller connects, microcontroller output mouth and impulse output circuit electricity
Connection, microcontroller are controlled and are handled using singlechip chip；
Power amplification circuit is used to receive music voltage signal and is enlarged into the audio power signal of predetermined power, and inputs
Photoelectric coupled circuit makes music voltage signal；
Photoelectric coupled circuit is used to be converted to power amplification circuit amplified audio power signal impedance, and passes through optocoupler electricity
Extra audio power signal is isolated in road, avoids work and identification to subsequent conditioning circuit from having interference, due to usual sound
The frequency of frequency output is 30~3k hertz and differs, and the frequency that actually can serve as rhythm regular movements only needs a part, without all making
With, therefore audio power signal is converted to by light by photoelectric coupled circuit, according to the impedance of the intensity of light adjustment output, and then will be more
Filtering is isolated in remaining audio power signal；
Frequency power signal is carried out being converted to direct current using charge and discharge circuit after photoelectric coupled circuit transimpedence
Press signal output, impedance made of being converted using charge and discharge circuit and by optocoupler exported according to audio variation
D. c. voltage signal；
Microcontroller is used to being converted to the d. c. voltage signal that charge and discharge circuit exports into the output of intensity square wave, and simultaneously
By programming, intermediate frequency or Low Medium Frequency square wave are exported using pin, to control the output of impulse output circuit.
As shown in Fig. 2, power amplification circuit is mainly made of LM4890 power chip and some resistance capacitances, photoelectric coupled circuit
It mainly include EL817 optocoupler, charge and discharge circuit is composed in parallel by a certain size resistance capacitance, and discharge time constant is answered small
In music rhythm (or intensity) period of change.The timeconstantτ of charge and discharge circuit determines the velocity of discharge, therefore should be selected in one
In fixed suitable range.If too small, discharge too fast, data transfer rate is not caught up with, and will lead to output intensity gear change not
Too continuous, kick is larger.If too big, discharge too slow, voltage fluctuation does not catch up with music rhythm (or intensity) pace of change, can lead
It causes output intensity gear change too slow, can not embody music rhythm (or intensity) variation.Time constant is determined by the value of R and C
, this circuit uses parallel resistance for 10K Ω, and capacitor is 220 μ F.
Its main body of microcontroller is singlechip chip STC15W4K32S4, has 8 ADC conversion ports, wherein this circuit
Analog-to-digital conversion is carried out to audio voltage signal using the port P1.5, the voltage signal that charge and discharge circuit exports is converted into number
Word signal, this, which is converted, to be arranged by software and conversion speed is 180 clock, take 8 result formula are as follows:
In formula: Vin is music direct current signal to be converted；VCC is supply voltage.
Finally lead to microcontroller programming again and the digital signal converted is become into intensity value, output intensity square wave, with control
Impulse output circuit output processed.
Impulse output circuit as shown in figure 3, audio power signal via microcontroller analog-to-digital conversion be intensity square wave, intensity
The width of square wave changes with music signal, and the strong square wave of signal is wide, and the weak square wave of signal is narrow.By integrating circuit such as R6, C15 by square wave
Become DC voltage, square wave Width funtion is high, and the narrow voltage of square wave is low.The base current of this voltage control triode Q3.Q3 transmitting

Together.
When its work, power amplification is transported to by C23 capacitor by the audio voltage signal that player conveying comes first
Circuit is transformed into audio power signal, all the way by SPEAKER loudspeaker sounding, is sent to the input of EL817 optocoupler by R33 all the way
It holds, when a current is large strong light, output impedance is small, otherwise output impedance becomes larger.Output end one meets power supply (VCC) through R50, separately
One is connected to charge and discharge circuit and converts to impedance, the resistance that will be changed with music rhythm regular movements using charge and discharge circuit
Anti-rotation is changed to d. c. voltage signal, and the analog-to-digital conversion port for being finally coupled to microcontroller carries out modulus to audio power signal and turns
Change, to convert analog signals into digital signal, eventually pass through microcontroller programming control output intensity square wave and it is low in
Frequency or intermediate frequency square wave, intensity square wave export by impulse output circuit corresponding with sound with Low Medium Frequency or the control of intermediate frequency square wave
The treatment pulse of happy rhythm regular movements variation.
Using this kind of method, different " prescription " can not only be extracted according to its rhythm regular movements from different music, and
And the frequency of the square wave of its output can be set by microcontroller, and then can send out for Low Medium Frequency or intermediate frequency one of which frequency
While treating pulse out, moreover it is possible to treat the output that pulse carries out Strength Changes to it according to the rhythm regular movements of different music.And
And due to when being converted audio voltage signal, using photoelectric coupled circuit and charge and discharge circuit, to realize pair
Extra musical power signal is isolated etc., to avoid interfering the output of subsequent conditioning circuit, so that it is influenced ADC and is turned
The accuracy changed, in addition to can equally be well applied in other higher fields of precision demand for electrotherapy.
Simply to illustrate that technical concepts and features of the invention, its purpose is allows in the art above-described embodiment
