Embodiment two
With reference to Fig. 2, show the flow chart of the dust-proof network detecting method of the embodiment of the present invention two, can specifically include as follows
Step：
Step 201, when the sounding parameter of the target utterance device in mobile terminal meets preset condition, acquisition target hair
Multiple second impedance values of acoustic device and multiple second frequency values of voice signal.
In embodiments of the present invention, when mobile terminal does not dispatch from the factory or just dispatches from the factory, the Air Filter of target utterance device is also
In more clean state, therefore the sounding such as the sound pressure level of target utterance device, loudness value parameter will meet preset condition,
It is that sounding parameter is in normal parameter area, at this point, mobile terminal can be various by target utterance device broadcasting
The voice signal of frequency, meanwhile, by the analog-digital converter in mobile terminal, with the input voltage of predetermined period acquisition voice coil
Value, at this time corresponding input current value and the at this time corresponding second frequency value of voice signal.Then, mobile terminal can incite somebody to action
Each input voltage value divided by corresponding input current value, you can obtain multiple second impedance values.By the week in preset duration
Phase property gathers, and mobile terminal can obtain one-to-one multiple second impedance values and multiple second frequency values.
For example, target utterance device can be loud speaker, when mobile terminal does not dispatch from the factory namely the hair of target utterance device
When sound parameter meets preset condition, mobile terminal can gather multiple second impedance value Z of loud speaker1, Z2, Z3..., Zn,
And multiple second frequency value P of voice signal1, P2, P3..., Pn, wherein, Z1With P1It is corresponding, Z2With P2It is corresponding, Z3With P3
It is corresponding ..., ZnWith PnIt is corresponding.
Step 202, according to multiple second impedance values and multiple second frequency values, reference impedance curve is generated.
In embodiments of the present invention, the realization method of this step can include：Using multiple second frequency values as abscissa, with
Multiple second impedance values are ordinate, according to the size order of multiple second frequency values, generate original impedance curve；To original resistance
Anti- curve is fitted processing, obtains reference impedance curve.
The block curve shown in Fig. 3 is reference impedance curve, with reference to Fig. 3, when target utterance device plays different frequency
Voice signal when, the real-time impedance of target utterance device is different.
For example, mobile terminal can be with multiple second frequency value P1, P2, P3..., PnFor abscissa, with multiple second
Impedance value Z1, Z2, Z3..., ZnFor ordinate, according to the size order of multiple second frequency values, generation original impedance is bent
Then line is fitted processing to original impedance curve, the solid line obtained in reference impedance curve namely Fig. 3 shown in Fig. 3 is bent
Line.
Step 203, the resonant frequency value of reference impedance curve is set as default resonant frequency value.
In embodiments of the present invention, reference impedance curve reaches corresponding frequency values during impedance peak-peak, is target
The resonant frequency value of sound-producing device, when the Air Filter of target utterance device is blocked, target utterance device is at resonant frequency
Impedance variations, become apparent compared with other frequencies, therefore, mobile terminal can be by the resonant frequency value of reference impedance curve
It is set as the frequency reference of default resonant frequency value, as a comparison impedance value.
It is sent out at different frequencies it should be noted that can be seen that target utterance device from the reference impedance curve in Fig. 3
Impedance value during sound has larger difference, therefore, if without considering voice signal frequency namely do not set frequency base to specific impedance
Standard so as to directly compare impedance value, will easily generate erroneous judgement, and then can reduce the accuracy rate of definite Air Filter exception.
For example, the resonant frequency value 780Hz (hertz) of reference impedance curve shown in Fig. 3 can be set as by mobile terminal
Default resonant frequency value.
Step 204, impedance value corresponding with default resonant frequency value in reference impedance curve is set as default impedance value.
In embodiments of the present invention, mobile terminal can be by resistance corresponding with default resonant frequency value in reference impedance curve

It should be noted that since the performance of the sound-producing device of same model is essentially identical, in practical applications, in advance
If can be directed to each sound-producing device actually measured for resonant frequency value and default impedance value, it is of course also possible to it is actually measured some
After the resonant frequency value of sound-producing device and corresponding impedance value, store it in each mobile terminal, it is standby as reference data

This step is similar with the realization process of above-mentioned steps 101, and this will not be detailed here.
For example, when the loud speaker sounding in mobile terminal, multiple first impedance value Y of loud speaker are gathered1, Y2,
Y3..., YnAnd multiple first frequency value X of voice signal1, X2, X3..., Xn, wherein, Y1With X1It is corresponding, Y2With
X2It is corresponding, Y3With X3It is corresponding ..., YnWith XnIt is corresponding.
Step 206, according to multiple first impedance values and multiple first frequency values, target impedance curve is generated.
This step is similar with the realization process of above-mentioned steps 102, and this will not be detailed here.
For example, mobile terminal can be with multiple first frequency value X1, X2, X3..., XnFor abscissa, with multiple first
Impedance value Y1, Y2, Y3..., YnFor ordinate, according to the size order of multiple first frequency values, generation original impedance is bent
Then line is fitted processing to original impedance curve, the dotted line obtained in target impedance curve namely Fig. 3 shown in Fig. 3 is bent
Line.
Step 207, target impedance value corresponding with default resonant frequency value in target impedance curve is determined.
This step is similar with the realization process of above-mentioned steps 103, and this will not be detailed here.
For example, mobile terminal can be determined in target impedance curve shown in Fig. 3, with default 780Hz pairs of resonant frequency value
The target impedance value answered is 10.7 Ω.
Step 208, when default difference between impedance value and target impedance value is more than preset difference value, target utterance is determined
The Air Filter of device exists abnormal.
In embodiments of the present invention, when the Air Filter of target utterance device is blocked, the space of meeting compressed air vibration,
It is hindered so as to be generated to vibration of membrane of shaking in target utterance device, is equivalent to the impedance value for reducing target utterance device, therefore,
When the difference preset between impedance value and target impedance value is more than preset difference value, mobile terminal can determine that target utterance fills
There is abnormal namely definite Air Filter and be blocked in the Air Filter put.
In addition, when the difference preset between impedance value and target impedance value is less than or equal to preset difference value, it is mobile whole
End can determine that the Air Filter of target utterance device is not blocked or stopping state is not serious.
For example, mobile terminal can determine that the difference between 10.7 Ω of default 11.9 Ω of impedance value and target impedance value is
1.2 Ω, the difference are more than 0.8 Ω of preset difference value, so as to which mobile terminal can determine that the Air Filter of loud speaker has exception.
Step 209, show to prompt the Air Filter of target utterance device to there is abnormal prompt message and for carrying
Show the advisory information that the Air Filter needs of target utterance device are cleared up.
It in embodiments of the present invention, can be with after mobile terminal determines the Air Filter of target utterance device there are exception
Prompting frame is popped up, and shows to prompt the Air Filter of target utterance device to there is abnormal prompt message in the prompting frame,
So as to when user views the prompt message, know the situation that the Air Filter of target utterance device is blocked in time.Into
One step, mobile terminal can also show to prompt in the prompting frame Air Filter of target utterance device to need that clears up to build
Information is discussed, so as to provide feasible Air Filter treatment measures to the user, for example " Air Filter cleaning procedure please be open！", " please be timely
Contact department after sale is cleared up！" etc..
For example, mobile terminal can pop up prompting frame, and " loud speaker Air Filter is different for display reminding information in the prompting frame
Often！" and show that advisory information " please contacts department after sale to be cleared up in time in the prompting frame！”.
In embodiments of the present invention, mobile terminal can when the sounding parameter of target utterance device meets preset condition,
According to multiple second frequency values of multiple second impedance values of the target utterance device of acquisition and voice signal, reference impedance is generated
Then the resonant frequency value of reference impedance curve is set as default resonant frequency value by curve, and by reference impedance curve with
The default corresponding impedance value of resonant frequency value is set as default impedance value, so as to establish comparison benchmark.Mobile terminal can be with afterwards
In target utterance device sounding, according to multiple the of multiple first impedance values of the target utterance device of acquisition and voice signal
One frequency values generate target impedance curve, it is then determined that target resistance corresponding with default resonant frequency value in target impedance curve
Anti- value, so as to which when default difference between impedance value and target impedance value is more than preset difference value, mobile terminal can determine mesh
