As shown in Figure 8, in specific implementation process, audio signal processing circuit 32 is comprised of low-pass filter circuit, half cycle amplifying circuit, peak-detector circuit, differential amplifier circuit and valley signal extracting circuit, utilize amplifier OP1, capacitor C 2, resistance R 2 and resistance R 5 to form low-pass filter circuit, promote the low frequency part in audio signal, the frequency range of combining music sound intermediate frequency signal, the cut-off frequency of described low-pass filter circuit is 200Hz～500Hz.
Audio signal enters the half cycle amplifying circuit from a point after by low-pass filter circuit, due to resistance R 1 and diode D1 composition half cycle rectifier, when the voltage of input is greater than earthed voltage, diode D1 cut-off, the positive half cycle of input signal enters amplifier OP2 in-phase input end by resistance R 1, the gain of amplifier OP2 is controlled by resistance R 3 and resistance R 4, so c point output audio half cycle signal.
Audio frequency half cycle signal enters peak-detector circuit from the c point, because the resistance of resistance R 6 is far longer than resistance R 8, when the positive half cycle of an audio signal is inputted, signal makes capacitor C 2 quickly charge to crest voltage by resistance R 6 and diode D2, after signal reaches peak value, capacitor C 2, by resistance R 8 electric discharges, makes the envelope signal of d point output audio half cycle signal.
Envelope signal is exported from the d point, during due to a continuous music of broadcasting, the amplitude envelops line of audio signal can not hang down ground level, and certain DC component arranged, if signal directly is transferred to the synchronous sound control appliance, control appliance can not reach maximum dynamic range, for removing the DC component of d point output signal, the signal of d point output is divided into two-way and is input to respectively amplifier OP3 and amplifier OP4, after cushioning by amplifier OP4, one road signal of d point output extracts the signal valleies by diode D3 and capacitor C 3, when amplifier OP4 output voltage during higher than the voltage of diode D3 positive terminal, diode D3 cut-off, capacitor C 3 is slowly discharged by resistance R 10, more than capacitor C 3 and resistance R 10 time constants are generally got 1s, thereby the valley envelope in e point output signal.
Another road signal of d point output is sent to the normal phase input end of amplifier OP3, amplifier OP3 is the differential amplifier circuit of, the d point is the positive input, the e point is anti-phase input, the signal of e point output is d point output signal valley envelope, therefore, the signal of amplifier OP3 output is Vo=(Vd-Ve) * G, wherein Vo is amplifier OP3 output signal voltage, the voltage that Vd is d point output signal, the voltage that Ve is e point output signal, the gain that G is amplifier OP3, gain is determined by resistance R 7 and resistance R 9, because output signal is that d point signal and its valley envelope signal subtract each other, therefore amplifier OP3 has removed the DC component of d point signal, only export the value that an audio frequency signal amplitude changes, the dynamic range of this value is larger, meet the sample requirement of master controller 31.
According to the foregoing circuit structure, the change of the light of whole system can combine with the rhythm change of music in power amplifier, thereby realizes the acousto-optic synchronous effect.
The invention allows for a kind of control method of night lamp decoration acousto-optic synchronous control system, carry out according to following steps:
The first step: acoustic control main frame 3 carries out acquisition and processing by the audio signal of 32 pairs of power amplifier outputs of audio signal processing circuit, thereby and carry out AD sampling acquisition sampled audio signal value by master controller 31, in implementation process, master controller 31 adopts 8 bit AD samples, gained sampled audio signal value means with 8 bits, and span is 0～255;
