Further referring to Fig. 3, the control method of the sound equipment play system of the invention based on global communications network manipulation,
Comprise the following steps：
Reception signal：Data receiver center 10 receives the music type mark that each audio player 12 plays music
The signal of signal, the self-test parameter of each audio player 12；The signal of self-test parameter is by the biography in audio player 12
CPU in sensor 125 carries out A/D to the voltage of the operating point of the power tube in audio power amplifier 121 and is converted to data；Data
Reception center 10 receives the music type marking signal that each audio player 12 plays music, described music type mark
Will signal is to carry out A/D to the music electrical signal played by the CPU of the sensor 125 in audio player 12 to be converted to
Amplitude versus frequency characte data, per second to sample 10 times, 9 milliseconds of sampling every time；
The generation control signal of data receiver center 10 sends control signal by the network control center 11 and some sound equipment is broadcast
Device 12 is put to be adjusted and control：The first step, data receiver center 10 receive sensor 125 and detect audio power amplifier 121
Inherent parameters, such as detect the final power output tube BIAS magnitudes of voltage of well-known audio power amplifier, compare sound
The data that frequency power amplifier prestores when dispatching from the factory, judge that the inherent parameters of audio power amplifier are set if appropriate for lasting promotion by abovementioned steps
The audio amplifier of parameter is determined, if the drift of inherent parameters sends control beyond prestoring the 15% of scope by the network control center 11
Signal-off audio power amplifier 121 processed and the emm message that the BIAS magnitudes of voltage of adjustment power amplifier tube are provided；If itself joins
Several drifts within the 115%-85% scopes for pre-stored values of dispatching from the factory, then into second step；Second step, compare amplitude versus frequency characte data
Judge music type with pre-stored data, the envelope curve of amplitude versus frequency characte is established by the data of acquisition, using the mould of Similarity matching
The musical database that prestores of formula search judges music type, have frequency higher than 11KHz, amplitude not less than average value 30%,
The music of 10% audio frequency component of total ascent time many music total times is determined as higher sound music, have frequency less than 150Hz,
Amplitude is determined as relatively low not less than the 30% of the average value, music of 10% audio frequency components of total ascent time many music total times
Sound music, the situation that both has are determined as Larger Dynamic music, are in addition inclined middle pitch music；It is uncomfortable for inclined middle pitch music
Frequency equilibrium distributor circuit enters the 3rd step in whole audio amplifier；For higher sound music, frequency equilibrium distribution electricity in audio amplifier 122 is adjusted
The high pitch frequency unit 131 on road 13, see that Fig. 3, the first relay K1 are controlled as contact and make second resistance R2 short-circuit, will be more
High fdrequency component be sent into high pitch loudspeaker, equivalent to lifting high pitch frequency range gain, to improve the broadcasting decibel value of high pitch frequency range, from
And realize the treble audio composition of compensation shortcoming and enter the 3rd step；For relatively low sound music, frequency equilibrium point in audio amplifier 122 is adjusted
Middle pitch frequency unit 132 with circuit 13, see that Fig. 3, the second relay K2 allow 3rd resistor R3 to produce series connection and made by control contact
With, by more low frequency components be sent into Squawker, equivalent to lifting bass frequency range gain, so as to realize compensation shortcoming
Audio bass composition enters the 3rd step, for Larger Dynamic music, sees that Fig. 3, the first relay K1 are controlled as contact and allow the second electricity
R2 short circuits are hindered, more high fdrequency components are sent into high pitch loudspeaker, the second relay K2 allows 3rd resistor R3 to produce by control contact
More low frequency components are sent into Squawker by life series connection effect, equivalent to lifting high pitch and the gain of bass frequency range, so that
Realize that the high pitch of compensation shortcoming enters the 3rd step with audio bass composition；3rd step, if the music played does not contain 8-13Hz α
Frequency of brain wave composition, then audio player is allowed to enter the normal play music stage；If the music played contains 8-13Hz α
Frequency of brain wave composition, see Fig. 3, the 3rd relay K3 is by the special infrasound acoustical generator of the interface J5 connections of control contacting the 5th
Part, the first relay K1, which is controlled as contact disconnection, allows second resistance R2 series connection to enter circuit, reduces high fdrequency component and is sent into high pitch
Loudspeaker, it is optimal to reach α E.E.Gs to reduce the broadcasting decibel value of high pitch frequency range equivalent to the gain for reducing high pitch frequency range
Health-care effect, and allow audio player to enter the normal play music stage.
Audio player plays：The audio player for being detected as normal and remote setting parameter is carried out to music
Play.
In the present embodiment, also include investigation user before reception signal and the personalized control signal for listening music be set,
And the personalized control signal is transmitted to the network control center and stored, in case subsequently being sent according to the needs of user individual
Property control signal adjustment play music, user listen music personalized control signal include control user play music loudness
With the music time, the loudness for playing music, Fig. 3 is seen, by the microprocessor of the sensor 125 in audio power amplifier 121
The voltage effective value at the A/D conversion I/O mouth detection first interface J1 both ends of device, the voltage effective value of audio power amplifier 121 go out
Factory's maxima and minima has been prestored into data receiver center, such as music loudness divides 100 lattice, 1-6 by logarithmic curve
Children within year listen to music, and for the maximum of the loudness of music no more than 35 lattice, the network control center 11 sends control letter
The upper limit of number remote control music loudness, user can not scene directly change and adjust, if the loudness of user's broadcasting sound equipment is excessive,
The network control center 11 sends signal and remotely closes the audio player 12；If user plays time and the sound of agreement of music
Happy reproduction time is not inconsistent, and the network control center 11 sends control signal and remotely closes the audio player 12.
Disclosed above is only several specific embodiments of the present invention, but the present invention is not limited to this, any ability
What the technical staff in domain can think change should all fall into protection scope of the present invention.
