Step 103: according to the first pumping signal, determining the second pumping signal.
Specifically, the second pumping signal is for driving driver.
The process of the second pumping signal, which is illustrated, to be determined according to the first pumping signal to terminal below.
In the first instance, terminal is directly using the first pumping signal as the second pumping signal.
In second example, terminal is filtered the first pumping signal, the excitation that will be obtained after filtering processing
Signal is as the second pumping signal.
In third example, the first pumping signal is normalized in terminal, by obtaining after normalized

Second embodiment of the present invention is related to a kind of production method of pumping signal, and present embodiment is implemented to first
The further refinement of mode, specifically illustrates: terminal carries out DC processing to initial displacement signal, and believes the first excitation
Number be filtered and/or normalized in the case where, the generation process of pumping signal.
Specifically, as shown in Fig. 2, in the present embodiment, include step 201 to step 205, wherein step 203 with
Step 102 in first embodiment is roughly the same, and details are not described herein again.Difference is mainly introduced below:
Step 201: obtaining second displacement signal.
Specifically, second displacement signal is initial displacement signal.
It should be noted that it will be understood by those skilled in the art that initial displacement signal can be from displacement signal library
It obtains.Wherein, the displacement signal by pre-setting is stored in displacement signal library.Terminal can therefrom choose at random a displacement

Desired displacement waveform generate the first displacement signal, the first displacement signal inputted eventually and according to desired displacement waveform
End.Present embodiment does not limit the acquisition modes of initial displacement signal.
Step 202: DC processing being carried out to second displacement signal, obtains the first displacement signal.
Specifically, terminal after obtaining second displacement signal, removes the DC component in second displacement signal, will remove
Signal after DC component is as the first displacement signal.
In one example, the method that terminal goes DC component are as follows: direct current submodule is gone by terminal, to second displacement
Signal carries out DC processing.Wherein, the transmission function for removing direct current submodule is
In formula o, r [n] indicates to go the output signal of direct current submodule, i.e. the first displacement signal, and direct current is removed in s [n] expression
The input signal of submodule, i.e. second displacement signal, len indicate the signal length of second displacement signal.
It should be noted that it will be understood by those skilled in the art that others can also be used to have and gone in practical application
The transmission function of direct current function, as the transmission function for removing direct current submodule, herein by way of example only, present embodiment is unlimited
System removes the specific formula of the transmission function of direct current submodule.

The pumping signal of generation be can be avoided during driving driver, motor spring receives damage because of the asymmetric stress of long-time
It is bad.
Step 203: being based on displacement-excitation transmission function, the first displacement signal is handled, obtain the first excitation letter
Number.
Step 204: the first pumping signal being filtered, third pumping signal is obtained.
Specifically, can pass through to avoid the high frequency section in the first pumping signal from exciting other mode of driver
Filtering processing is formed to the first pumping signal in the mode of bidirectional filtering.
The method that filtering processing is formed to the first pumping signal to terminal below is illustrated.

Word signal carries out first time filtering in order, carries out first time reverse to the result of first time filtering, the knot reverse to first time
Fruit carries out second and filters, and carries out second to the result of second of filtering and reverses, the result that second is reversed is as third
Pumping signal is to get the output sequence being distorted to accurate zero phase.
It is assumed that including N number of digital signal in the first pumping signal.The first step, terminal is to the number in the first pumping signal
Signal carries out first time filtering processing.The process of filtering may be expressed as: y in the time domain for the first time1[n]=x (n) * h [n], 0≤n
≤ N-1, x (n) indicate digital signal to be treated, and h [n] indicates the transmission function of filter in the time domain, y1[n] indicates x
(n) result of corresponding first time filtering；It may be expressed as: Y in a frequency domain1[k]=X [k] × H [k], 0≤k≤N-1.Wherein, X
[k] indicates digital signal to be treated, and H [k] indicates the transmission function of filter in a frequency domain, Y1[k] indicates that X [k] is corresponding
First time filtering result.Second step, terminal reverse the result of first time filtering.For the first time reverse process when
It may be expressed as: y in domain2[n]=y1[N-n], y2[n] indicate that x (n) corresponding first time reverses as a result, y1[N-n] indicates x
(N-n) result of corresponding first time filtering；It may be expressed as: in a frequency domainY2[k] indicates that X [k] is corresponding
For the first time reverse as a result,Indicate the result of X [N-k] corresponding first time filtering.Third step, terminal is to inverse for the first time
The result turned carries out second and filters.The process of second of filtering is represented by y in the time domain3[n]=y2(n) * h [n], wherein
y3[n] indicates the result of x (n) corresponding second of filtering；It is represented by Y in a frequency domain3[k]=Y2[k] × H [k], Y3[k] table
Show the result of corresponding second of the filtering of x (n).4th step, terminal carry out second to the result of second of filtering and reverse.Second
The process of secondary reverse is represented by y [n]=y in the time domain3[N-n], y [n] indicate it is that x (n) corresponding second is reversed as a result,
y3[N-n] indicates the result of x (N-n) corresponding second of filtering；It is represented by a frequency domainY [k] indicates X
It is that [k] corresponding second is reversed as a result,Indicate the result of X [N-k] corresponding second of filtering.All y [n] structures
At third pumping signal.Can obtain through the above, Y [k]=X [k] | H [k] |2, it is seen then that the treatment process does not result in phase misalignment
Very.
It is noted that being filtered to pumping signal, can improve due to the high fdrequency component in pumping signal
Brought vibration noise.
Step 205: third pumping signal being normalized, the second pumping signal is obtained.
Specifically, third pumping signal is normalized in terminal, finally obtained second pumping signal is made to exist
Between [- 1,1].For example, the second pumping signal is between -1V to 1V when driver is the driver of voltage driving.
It should be noted that the above is only limit for example, not constituting to technical solution of the present invention.
Compared with prior art, the production method of the pumping signal provided in present embodiment, terminal can be based on displacements-
Transmission function is motivated, displacement signal is converted into pumping signal, enables the terminal to drive driver to generate according to displacement signal
Corresponding displacement obtains desired haptic effect.Since terminal is to drive driver based on displacement signal, user touches in design
When feeling effect, the corresponding displacement of haptic effect is provided, desired haptic effect can be obtained, carried out haptic effect convenient for user and set
Meter.In addition to this, before determining pumping signal according to displacement signal, DC processing is carried out to displacement signal, can be avoided
For the pumping signal of generation during driving driver, motor spring receives damage because of the asymmetric stress of long-time.To excitation
Signal is filtered, and can improve the vibration noise as brought by the high fdrequency component in pumping signal.
