Unit 31；The order unit 31 is used to, according to the control information, reduce the voltage and/or frequency of the CPU and/or GPU4
Rate；The order unit 31 is EC or BIOS.Normally, the PCH32 is as the south bridge inside the CPU4, receiving
State control information after by LPC_BUS and SPI_BUS by control information be transferred to BIOS or EC, the BIOS or EC receive simultaneously
After confirming the control information, the CPU and/or GPU4 is being returned to by sending out PROCHOT# notices, is being reduced to realize
The voltage and/or frequency of the CPU and/or GPU4.
In the embodiment of the present invention one, the electronic equipment is a laptop, is set in the laptop
It is equipped with CPU, digital microphone, audio codec and control module, the number microphone and the audio decoder are mutually electric
Property connection, the audio decoder is electrically connected with the CPU phases, and the control module specifically includes PCH and order unit, institute
It states the south bridge that PCH is CPU to be arranged in the CPU, the order unit is BIOS, the order unit and CPU phases electricity
Property connection, when the laptop starts, since starting current is electric by MLCC capacitances inside laptop and RLC
Road, thus generate violent vibration and cause noise,
As shown in figure 3, Fig. 3 is the sound signal intensity schematic diagram of embodiment one, voice signal of the present invention is being applied
Control method before, the intensity measurement result of the noise is as shown in the chart of the upper figure in Fig. 3, when the voice signal of generation
Frequency is in 1000hz to 11000hz, when intensity is more than 10 decibels, as can generate shadow to user under quiet environment
Loud noise, when between 5 decibels to 0 decibel, as human ear can identify but be not enough to the sound having an impact, intensity intensity
It is the sound that human ear can not be heard when less than 0 decibel, when the frequency of the voice signal of generation is in 11000hz to 18000hz,
When intensity is more than 5 decibels, the noise that can be as had an impact to user under quiet environment, intensity is at 2 decibels to 0 point
When between shellfish, as human ear can identify but be not enough to the sound having an impact, and when intensity is less than 0 decibel, can not be listened for human ear
The sound seen.Shown in chart by the upper figure in analysis chart 3, the intensity measurement of noise is, frequency be 1000hz extremely
Between 2000hz, 4000hz is between 5000hz, and 13000hz is between 15000hz, will produce can be under quiet environment
To the noise that user has an impact, and in most cases, the sound that human ear can identify can be all generated；Therefore, in order to control
The voice signal is made, we set when frequency is 1000hz to 11000hz (including 11000hz), in advance predetermined threshold value to
If threshold value is 5 decibels；Frequency be 11000hz (do not include 11000hz) to 18000hz when, predetermined threshold value is 2 decibels.It is described
Predetermined threshold value is arranged in the audio codec.
At this point, when starting the laptop, the number microphone starts to acquire MLCC capacitances and described
Generated voice signal when the started operation of rlc circuit, and the voice signal is transferred to by clock lines and data lines
The audio codec, the audio codec the voice signal is encoded, decode and correlation analysis it is same
When, judgement is compared with predetermined threshold value to the intensity of the voice signal, judges to obtain, when frequency be 1000hz extremely
Between 2000hz, 4000hz is between 5000hz, is to generate to be more than the predetermined threshold value when 13000hz is between 15000hz
Voice signal, that is, judging result is, the voice signal has the case where being more than the predetermined threshold value, and therefore, output reduces
The voltage of the CPU and/or the control information of frequency, and the control information is transferred to the south being arranged inside the CPU
Bridge：The PCH, the PCH are transferred to by LPC_BUS and SPI_BUS by information is controlled after receiving the control information
BIOS, the BIOS or EC after being received and confirmed by the control information, by send out PROCHOT# notices return to it is described
CPU, to realize the voltage and/or frequency that reduce the CPU.
After the voltage and/or frequency for reducing the CPU, the intensity measurement result of the noise is such as figure below in Fig. 3
Shown in chart, by analysis table it is found that after the voltage and/or frequency for reducing the CPU, the voice signal is in frequency
Intensity when 1000hz to 18000hz is also not above 0 decibel, therefore, is reducing institute at 0 decibel hereinafter, when highest
After the frequency for stating CPU, the number collected voice signal of microphone is respectively less than predetermined threshold value, therefore, it is not necessary to again to described
CPU carries out frequency reducing or decompression, the noise of the electronic equipment on startup are also successfully controlled.
More than, schematic description only of the invention, it will be recognized by those skilled in the art that in the work without departing from the present invention
On the basis of making principle, a variety of improvement can be made to the present invention, this is all belonged to the scope of protection of the present invention.
