As shown in Figure 7; Be provided with master controller 31, audio signal processing circuit 32 and MAX485 module 33 in the said acoustic control main frame 3; The input of said audio signal processing circuit 32 is provided with the tone frequency channel wire interface; This audio signal processing circuit 32 is used to realize filtering, amplify and extract the analog amplitude value of audio signal, and the output of this audio signal processing circuit 32 is connected with an AD input of master controller 31, and master controller 31 obtains the digital amplitude values of said audio signal through the AD sampling; And confirm corresponding light controling signal according to this digital amplitude values; Said light controling signal carries out level conversion through the TXD pin output of master controller 31 through said MAX485 module 33, is sent in the said acoustic control extension set 2 through the RS485 bus at last; Adopt MAX485 module 33 to carry out sending on the RS485 bus after the level conversion, be convenient to the long Distance Transmission of control signal.
As shown in Figure 8; In the practical implementation process; Audio signal processing circuit 32 is made up of low-pass filter circuit, half cycle amplifying circuit, peak-detector circuit, differential amplifier circuit and valley signal extracting circuit, utilizes amplifier OP1, capacitor C 2, resistance R 2 and resistance R 5 to form low-pass filter circuit, promotes the low frequency part in the audio signal; The frequency range of combining music sound intermediate frequency signal, the cut-off frequency of said low-pass filter circuit are 200Hz～500Hz.
Audio signal is through getting into the half cycle amplifying circuit from a point behind the low-pass filter circuit; Because resistance R 1 is formed the half cycle rectifier with diode D1; When the voltage of input greater than earthed voltage, diode D1 ends, the positive half cycle of input signal gets into amplifier OP2 in-phase input end through resistance R 1; The gain of amplifier OP2 is by resistance R 3 and resistance R 4 controls, so c point output audio half cycle signal.
Audio frequency half cycle signal gets into the 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 imported; Signal makes capacitor C 2 quickly charge to crest voltage through resistance R 6 with diode D2, signal reach peak value later capacitor C 2 make the envelope signal of d point output audio half cycle signal through resistance R 8 discharges.
Envelope signal is from d point output, because when playing a continuous music, the amplitude envelops line of audio signal can not hang down ground level; And certain DC component is arranged, if signal directly is transferred to the sound Synchronizing Control Devices, 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 amplifier OP3 and amplifier OP4 respectively, and one road signal of d point output extracts the signal valley through amplifier OP4 buffering back by diode D3 and capacitor C 3, when amplifier OP4 output voltage is higher than the voltage of diode D3 positive terminal; Diode D3 ends; Capacitor C 3 is slowly discharged through resistance R 10, and capacitor C 3 is generally got more than the 1s with resistance R 10 time constants, thereby exports the valley envelope of signal at the e point.
Another road signal of d point output is sent to the normal phase input end of amplifier OP3, and amplifier OP3 is one a differential amplifier circuit, and the d point is the positive input; The e point is the anti-phase input, and the signal of e point output is a d point output signal valley envelope, therefore; The signal of amplifier OP3 output is Vo=(Vd-Ve) * G, and wherein Vo is an amplifier OP3 output signal voltage, and Vd is a d point output voltage of signals; Ve is an e point output voltage of signals, and G is the gain of amplifier OP3, and gain is by resistance R 7 and resistance R 9 decisions; Because the output signal is that d point signal and its valley envelope signal subtract each other, so amplifier OP3 removed the DC component of d point signal, only export the value of an audio frequency signal amplitude variation; The dynamic range of this value is bigger, satisfies 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 the power amplifier, thereby realizes the acousto-optic synchronous effect.
The utility model has also proposed a kind of control method of night scene lamp decoration acousto-optic synchronous control system, carries out according to following steps:

The 3rd step: acoustic control extension set 2 judges whether the sampled audio signal value equals 0:
If the sampled audio signal value equals 0, represent that promptly power amplifier do not emit music, then microcontroller 21 moves according to automatic gradual-change mode;
If the sampled audio signal value is not equal to 0, represent that promptly power amplifier emits music, then microcontroller 21 becomes pattern cycle circular flow according to the first saltus step pattern, the second saltus step pattern, the 3rd saltus step pattern and the forth jump;
The 4th step: microcontroller 21 is according to the luminance of corresponding light fixture in the determined mode of operation control lamp module 1 in the 3rd step.

In automatic gradual-change mode, give 8 corresponding RGB components of background light group with background colour red component VR, back color green component VG, background colour blue component VB assignment respectively, can realize the change of respective color.With state 0 is example; It is the brightest to make passive RGB tri coloured lantern 12 in 8 background light groups 121～128 the most secretly change to green by green; Then background colour red component VR is made as 0; VB is made as 0 with the background colour blue component, back color green component VG progressively is increased to 255 from 0 can realizes that other states by that analogy.
More than this pattern mainly be not have under the sound control signal input condition, fixture color is to change automatically in time, all background light groups are same color, the saltus step situation do not occur.
