Reference picture 3, the present invention provides a kind of light on and off screen control method based on ultrasonic wave, in the light on and off screen based on ultrasonic wave In control method first embodiment, being somebody's turn to do the light on and off screen control method based on ultrasonic wave includes：

Step S10, obtain ultrasonic frequency constant interval and the frequency constant interval that ultrasonic wave recipient receives Corresponding intensity variation curve；

Light on and off screen based on the ultrasonic wave control of the present embodiment is primarily adapted for use in by ultrasonic wave to sending this ultrasonic wave Sender carries out light on and off screen control.Ultrasonic wave sender is the equipment with screen display device, and it is sent out ultrasonic wave, is surpassed Acoustic receiver side receives to this ultrasonic wave sent, according to the parameter for sending and receiving ultrasonic wave, determines that ultrasonic wave is sent The displacement trend of side, and then ultrasonic wave sender bright screen or the screen that goes out are controlled according to displacement trend.This ultrasonic wave sender and ultrasound Ripple recipient can be integrated in same mobile terminal, and mobile terminal is used as ultrasonic wave sender and ultrasonic wave recipient simultaneously, Can be smart mobile phone or tablet personal computer, wherein being illustrated by taking smart mobile phone as an example.Smart mobile phone, which is provided with, to be sent out Send the ultrasonic wave sender of ultrasonic wave and the ultrasonic wave recipient of ultrasonic wave can be received, specifically, ultrasonic wave sender can integrate In the receiver of smart mobile phone, in the Mic for the smart mobile phone that ultrasonic wave recipient can be integrated in；So as to which receiver changes power Current signal become the signal of sound, ultrasonic signal is also sent out while the sound-reducing of transmission is come out, Mic exists The voice signal of reception is converted to while the signal of the electric current of strong and weak change is transmitted and also receives the ultrasound that receiver is sent Ripple signal.Smart mobile phone for being provided with two Mic of major-minor, voice signal is received when being set as by main Mic and be used for and conversing, and Secondary Mic is set as to be used for received ultrasonic signal, to avoid interfering with each other for signal.Understandably, ultrasonic wave is that frequency is big In 20KHz sound wave, so that the ultrasonic frequency that mobile terminal is sent out also is accordingly a certain frequency more than 20KHz, Such as 40KHz, this certain frequency for being more than 20KHz is the base frequency that ultrasonic wave sender sends ultrasonic wave.

In addition the displacement trend of the ultrasonic wave sender of the present embodiment is displacement trend of the mobile terminal relative to user, is used Family is held close for user or by from user during using mobile terminal, by mobile terminal, mobile terminal occurs close or remote From the displacement trend of user, relative movement between mobile terminal and user be present.And according to Doppler effect, sent out as ultrasonic wave The mobile terminal for the side of sending, when it is moved relative to user, if close to each other between the two, ultrasonic wave is compressed, and wavelength becomes Shorter, frequency becomes higher, that is, produces blue-shifted phenomenon；And if be located remotely from each other between the two, opposite effect can be produced, ultrasound The wavelength of ripple becomes longer, and frequency becomes relatively low, that is, produces Red Shift Phenomena；It is produced and the speed moved between the two is higher Effect it is bigger.Relative to the movement of user, it is substantially user during using mobile terminal, taken the present embodiment mobile terminal Play process of the mobile terminal close to user or remote user, it is contemplated that the speed that user picks up mobile terminal becomes within the specific limits Change, so that the change for the ultrasonic frequency that ultrasonic wave recipient receives also accordingly changes within the specific limits, this is frequency Rate excursion.Frequency range is the frequency caused by the relative motion between ultrasonic wave recipient and ultrasonic wave sound source Rate excursion, the frequency that ultrasonic wave recipient receives can be changed with this scope.So as to according to this frequency range The ultrasonic frequency constant interval that ultrasonic wave recipient receives is can determine that, this frequency constant interval is to become with base frequency in frequency The section of change gained in the range of change.In addition, the ultrasonic frequency that ultrasonic wave recipient receives has its corresponding intensity level, from And it is determined that after frequency constant interval, each frequency in frequency constant interval can correspond to corresponding intensity level, and in section Intensity corresponding to the frequency of all changes can then form intensity variation curve.Obtain the ultrasound that this ultrasonic wave recipient receives Intensity variation curve corresponding to wave frequency rate constant interval and the frequency separation, to determine movement of the mobile terminal relative to user Trend, controls the bright screen of mobile terminal or the screen that goes out.

Step S20, according to the frequency constant interval and corresponding intensity variation curve, determine the position of ultrasonic wave sender Move curve；

Further, the area that frequency constant interval and intensity variation curve corresponding with this frequency constant interval are formed Displacement available for the displacement, i.e. ultrasonic wave sender for characterizing ultrasonic wave sound source.Because single displacement data can not embody movement Mobile trend between terminal and user, it is thus necessary to determine that multiple displacements, movement is embodied by the numerical value change between multiple displacements Mobile trend between terminal and user, such as multiple numerical value show that mobile terminal and the distance between user are more and more nearer or more next It is more remote, then illustrate that mobile terminal has the mobile trend close to or away from user.Ultrasonic wave sender sends ultrasonic wave with a timing Between the cycle carry out, corresponding ultrasonic wave recipient also receives ultrasonic wave with cycle certain time, and the present embodiment obtains each time Frequency constant interval and corresponding intensity variation curve in cycle, each frequency constant interval and corresponding Strength Changes are bent Line is respectively formed corresponding area.Each area embodies mobile terminal relative to the displacement of user, passes through this size Change embodies the change of displacement.Specifically, the two-dimensional coordinate system of XY axles is established, X-axis is the time, Y-axis is displacement, by each time The area that frequency constant interval corresponding to cycle and intensity variation curve corresponding with this frequency constant interval are formed, as Y-axis On shift value point, multiple shift value points corresponding to multiple time cycles, displacement curve can be formed.With according to displacement curve The change of top offset, determine mobile terminal and the mobile trend of user.

Step S30, according to the displacement curve, control ultrasonic wave sender bright screen or the screen that goes out.

Further, in the two-dimensional coordinate system of displacement curve, positioned at Y-axis positive direction numerical representation method mobile terminal to User approaches, and then to characterize mobile terminal remote to user positioned at the numerical value of Y-axis negative direction.So that according to this positive and negative values, it is determined that Mobile terminal to user close to or away from, and according to close to or away from state realize the light on and off screen of mobile terminal.It is such as mobile whole When receiving incoming call, its bright screen is shown termination to incoming call, when determining the fortune between mobile terminal and user by displacement curve Dynamic trend be close, then mobile terminal is held close for answering to sending a telegram here by judgement user, so as to control mobile terminal to go out screen, with Reduce the energy consumption of mobile terminal；And when by displacement curve determine movement tendency between mobile terminal and user be it is remote, then Judge that the call of user has been completed to take mobile terminal from user, so as to control mobile terminal bright screen to show call-information Show, so that user understands talking state.

The light on and off screen control method based on ultrasonic wave of technical solution of the present invention, is received by obtaining ultrasonic wave recipient Ultrasonic frequency constant interval and the frequency constant interval corresponding to intensity variation curve；And according to this frequency constant interval The corresponding intensity variation curve with this frequency constant interval, determine the displacement curve of ultrasonic wave sender；So as to according to this position Curve is moved, controls ultrasonic wave sender bright screen or the screen that goes out.This programme is by directly characterizing the position of ultrasonic wave sender's moving direction Curve is moved, determines mobile terminal and the mobile trend of user, and then the bright screen of ultrasonic wave sender is controlled according to this mobile trend Or the screen that goes out, the judgement of mobile trend can be made more accurate, make the control of light on and off screen more accurate.

Further, it is described according to institute in another embodiment of light on and off screen control method of the present invention based on ultrasonic wave Displacement curve is stated, ultrasonic wave sender bright screen is controlled or the step of shielding of going out includes：

Step S31, multiple consecutive numbers strong points on displacement curve are obtained, to each data value at the multiple consecutive numbers strong point Average；

Step S32, the new data value using the average value as multiple consecutive numbers strong points, and according to the new data value shape Into new displacement curve；

Step S33, according to the new displacement curve, control ultrasonic wave sender bright screen or the screen that goes out.

Understandably, within a time cycle, there are numerous frequency constant interval and corresponding intensity variation curve institute The area figures of the numerous displacement of sign of formation, this numerous shift value may partly be located at Y-axis in two-dimensional coordinate system Positive direction may also partly be located at the negative direction of Y-axis.So as to which the result judged by it may be close to user for mobile terminal It is mobile to be possibly also distant form user's movement, there is the problem of judged result inaccuracy.In order to avoid the appearance of this problem, the present embodiment Numerical point on displacement curve is smoothed.Specifically, multiple consecutive numbers strong points on displacement curve are obtained, it is multiple to this Each data value at consecutive numbers strong point is averaged, and using this average value as multiple consecutive numbers strong points for averaging New data value.Refer to Fig. 6, when on displacement curve institute a little after average value is handled, will be handled by average value To all new data values form new displacement curve, according to new displacement curve, to control the bright screen of ultrasonic wave sender or the screen that goes out. New displacement curve is formed by the processing averaged to multiple consecutive numbers strong points on former displacement curve, displacement curve can be made On data point more accurately embody the displacement trend of mobile terminal.Multiple consecutive numbers strong points on displacement curve are wherein obtained, and The step of being averaged to each data value at this multiple consecutive numbers strong point includes：

Step S311, determine the value interval at multiple consecutive numbers strong points and predetermined number on displacement curve；

Step S312, the initial data point at multiple consecutive numbers strong points is determined according to the value interval, and according to described Beginning data point obtains consecutive numbers strong point corresponding with predetermined number from displacement curve；

Step S313, the consecutive numbers strong point is formed into data point combination, and data point combination is averaged.

Further, in order to which the numerical value averaged is more accurate, the data point averaged every time is set as portion Point repeat, such as first this 1st~10 data point on displacement curve is averaged, second to the 2nd~11 or the 3rd ~12 data points are averaged, and make the 2nd~10 or 3~10 data points repetitions averaged for the first time and for the second time, So that the result after averaging more is bonded the data point of former displacement curve.Wherein overlapping data amount check is true by value interval It is fixed, the 2nd~11 data point is averaged for the second time as described above, then value is at intervals of 1；And when second to the 3rd~12 When data point is averaged, then value is at intervals of 2.And how many individual numerical points are averaged, determined by predetermined number, it is such as pre- If number is 10, then 10 data points on displacement curve are averaged every time.The present embodiment is more on displacement curve by determining The value interval at individual consecutive numbers strong point and predetermined number, the multiple consecutive numbers strong points for determining to average every time according to value interval Initial data point.Exceptionally, the initial data point averaged first can be by making an appointment, and such as agreement is by displacement curve First data point as the initial data point averaged first.The initial data point subsequently averaged is then according to value Interval determines that such as initial data point first is 1, and value is 4 at intervals of 3, then secondary initial data point, third time then with Based on secondary initial data point 4, value is carried out with value interval 3, i.e. the initial data point of third time is 7.It is determined that After the initial data point of each value, then consecutive numbers corresponding with predetermined number is obtained from displacement curve with this initial data point Strong point, described above 1~10,4~13,7~16 etc..After the consecutive numbers strong point averaged every time is obtained, by this consecutive numbers Strong point forms data point combination, and the combination of this data point is averaged.Specifically, by corresponding to all data points in combinations of values Data value is done and computing, and will do business's computing with the result obtained by computing and predetermined number, and this business's operation result is data point The average value of combination.The present embodiment can make average value more by the way that the data point averaged every time is set as into part repeats Accurately, the mobile trend of mobile terminal can more be embodied.

It is described bent according to the displacement in another embodiment of light on and off screen control method of the present invention based on ultrasonic wave Line, controls ultrasonic wave sender bright screen or the step of shielding of going out includes：

Step S34, it is described according to the new displacement curve, control ultrasonic wave sender bright screen or go out screen the step of include：

Step S35, judges whether the numerical value on new displacement curve is more than first threshold, when more than first threshold, control Ultrasonic wave sender carries out the screen that goes out；

Step S36, judges whether the numerical value on new displacement curve is less than Second Threshold, when less than Second Threshold, control Ultrasonic wave sender carries out bright screen operation, and wherein first threshold is more than Second Threshold.

Understandably, during using mobile terminal, mobile terminal has closer and farther from user's two states user, Wherein mobile terminal and user's relative distance most far distance of user's arm.When both relative distance is in farthest shape State, and judge that the movement tendency of mobile terminal is close to user, now controls mobile terminal screen display of going out so unreasonable, possible user Not yet see the content of the caller identification on mobile terminal clearly.The movement tendency for working as judgement mobile terminal accordingly is remote user, Then control mobile terminal bright screen is also unreasonable immediately, and possible mobile terminal not yet reaches the position that user can see that its display screen Put, now bright screen can cause the electricity of mobile terminal to waste.So as to which the present embodiment is provided with first threshold and Second Threshold, first Threshold value is used for when the displacement trend between mobile terminal and user is close, and judging the displacement of mobile terminal and user is It is no allow mobile terminal and user distance it is near enough, Second Threshold is used for when displacement trend between mobile terminal and user is remote From when, judge whether the displacement of mobile terminal and user allow the distance of mobile terminal and user remote enough.Please further join According to Fig. 6, because judging close to by the Y-axis positive direction on displacement curve, the remote Y-axis negative direction by displacement curve judges, So as to which first threshold is more than Second Threshold, and first threshold is on the occasion of Second Threshold is negative value.Fig. 7 is refer to, when by smooth When numerical value on the displacement curve of processing is more than first threshold, i.e., mobile terminal is more than the first threshold to the distance moved close to user Value, then judge that the displacement trend between mobile terminal and user is close, and distance between the two reaches screen distance of going out, and carries out The screen that goes out processing；And when the numerical value on displacement curve is less than Second Threshold, i.e., mobile terminal is small to the distance away from user's movement In Second Threshold, then it is remote to judge the displacement trend between mobile terminal and user, and distance between the two reaches bright screen Distance, carry out bright screen processing.

Further, in another embodiment of light on and off screen control method of the present invention based on ultrasonic wave, the frequency becomes Changing section includes first interval and second interval, described according to the frequency constant interval and corresponding intensity variation curve, really The step of displacement curve for determining ultrasonic wave sender, includes：

Step S21, according to first interval and intensity variation curve corresponding with the first interval, determine the first face Product；

Step S22, according to second interval and intensity variation curve corresponding with the second interval, determine the second face Product；

Step S23, according to first area and second area, determine the displacement curve of ultrasonic wave sender.

Further, because frequency constant interval be changed with base frequency in frequency range obtained by section, And frequency range is the scope of a frequency values change for including coboundary and lower boundary, so as to which base frequency is in frequency Change between the coboundary of excursion and lower boundary, and including becoming greatly and diminishing.Frequency becomes with frequency based on wherein diminishing Change scope and do difference operation, become it is big then based on frequency done with frequency range and computing.Difference operation with and the difference of computing can Different frequency constant intervals is determined, it neutralizes first interval of the result obtained by computing for frequency constant interval, difference operation institute The result obtained is the second interval of frequency constant interval.If base frequency is f, frequency range is f1~f2, then the firstth area Between be (f+f1)~(f+f2)；Second interval is (f-f2)~(f-f1).It is determined that after this first interval and second interval, first Frequency in section and second interval corresponds to its respective intensity curve, and first interval starting point is corresponding with end point strong The closed area that angle value, the frequency range of first interval and the intensity variation curve of first interval are surrounded is as first Region.By second interval starting point intensity level corresponding with end point, the frequency range and second interval of second interval The closed area that is surrounded of intensity variation curve as second area.By intensity variation curve corresponding to first interval to The frequency range integration in one section can draw the size of first area, i.e. the first area.Pass through second interval pair The intensity variation curve answered can draw the size of second area to the frequency range of second interval integration, i.e., second Area.So as to according to this first area and second area, determine the displacement curve of ultrasonic wave sender, its specific steps:

Step S231, multiple differences of multiple first areas and second area are determined, and the multiple difference formed super The displacement data group of sound wave sender；

Step S232, the displacement data group is formed into displacement curve.

It is determined that the size of first area and the size of second area, i.e. the first area and second area it Afterwards, this first area and second area are done into difference operation, i.e. the first area subtracts second area, and the difference result of this difference operation is For the displacement of ultrasonic wave sender.The size of difference is the distance of displacement, and the positive negativity of difference is the direction of displacement, and difference is just Then mobile terminal moves close to user, and difference moves for negative then mobile terminal away from user.When the present embodiment is by obtaining each Between frequency constant interval and corresponding intensity variation curve, each frequency constant interval and corresponding Strength Changes in the cycle Curve is respectively formed corresponding first area and second area, i.e., multiple first areas and second area.By this multiple first area Difference operation is done with corresponding second area, obtains multiple differences, this multiple difference is formed to the displacement data of ultrasonic wave sender Group, wherein time cycle and size of the difference are comprised at least in each displacement data group, with big according to multigroup time cycle and difference Small formation displacement curve, mobile trend of the mobile terminal relative to user is determined, control the bright screen of mobile terminal or the screen that goes out.

Further, Fig. 4 is refer to, in the base of the first embodiment of light on and off screen control method of the present invention based on ultrasonic wave On plinth, the second embodiment of the light on and off screen control method of the invention based on ultrasonic wave, in a second embodiment, the acquisition are proposed Intensity variation curve corresponding to the ultrasonic frequency constant interval and the frequency constant interval that ultrasonic wave recipient receives Include before step：

Step S40, according to the default translational speed of ultrasonic wave sender, determine that ultrasonic wave recipient receives the frequency of ultrasonic wave Rate constant interval, and intensity variation curve corresponding with ultrasonic frequency constant interval.

Further, because mobile terminal receives the frequency change of ultrasonic wave, by relative between mobile terminal and user Motion causes, and frequency constant interval is then determined by the speed variation of relative motion.Understandably, mobile terminal and user it Between relative motion, its essence is user picks up mobile terminal during using mobile terminal, make mobile terminal and user people The relative motion that body trunk or head occur.The speed that user picks up mobile terminal changes within the specific limits, specific change Scope can be by way of test, it is determined that speed when most of user uses mobile terminal.This is met into most of user needs Default translational speed of the velocity interval asked as ultrasonic wave sender, and translational speed is preset according to this and determines that ultrasonic wave receives Side receives the frequency constant interval of ultrasonic wave.And the ultrasonic frequency that ultrasonic wave recipient receives has its corresponding intensity level, So as to it is determined that after frequency constant interval, each frequency in frequency constant interval can correspond to corresponding intensity level, and section Intensity corresponding to the frequency of middle all changes can then form intensity variation curve.Wherein according to the default shifting of ultrasonic wave sender The step of moving speed, determining the ultrasonic frequency constant interval that ultrasonic wave recipient receives includes：

Step S41, the base of ultrasonic wave is sent according to the default translational speed of ultrasonic wave sender and ultrasonic wave sender Plinth frequency, determine that ultrasonic wave recipient receives the frequency range of ultrasonic wave；

Step S42, according to the frequency range and base frequency, determine frequency constant interval.

Further, after the default translational speed of most of user's request is determined for compliance with, according to this default mobile speed The base frequency for the ultrasonic wave that degree and ultrasonic wave sender send, you can determine that ultrasonic wave recipient receives the frequency of ultrasonic wave Excursion.Specifically, according in Doppler effect, the relational expression between speed and frequency：

Wherein, f is the frequency for receiving ultrasonic wave, f₀It is the base frequency that ultrasonic wave is sent, c is that sound is aerial Spread speed 340m/s, Δ v are speed of the user relative to ultrasonic wave sound source, i.e., default translational speed.

So as to change frequencyThe default translational speed Δ v of cause is the number changed in certain limit Value, corresponding change frequency Δ f also change within the specific limits, as frequency range.Because frequency range is one The scope of frequency values change, including coboundary and lower boundary, the frequency that ultrasonic wave recipient receives is on the basis of base frequency On changed with this scope, i.e., change between coboundary and lower boundary.So as to according to frequency range and base frequency It can determine that the frequency constant interval that ultrasonic wave recipient receives.It is bent according to this frequency constant interval and corresponding Strength Changes Line, displacement curve is determined, realize the bright screen of mobile terminal or the screen that goes out.
