[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the embodiment of the present application is: obtain the initial waveform file of the linear motor driving the capacitive pen to vibrate; drive the capacitive pen to vibrate according to the initial driving file, and collect the actual waveform curve of the capacitive pen vibration; use the actual waveform curve to compare with the standard waveform curve of the capacitive pen vibration; modify the initial waveform file according to the comparison result to obtain the driving waveform file, and use the driving waveform file to drive the capacitive pen to vibrate.

[0048] Due to the influence of factors such as process and materials in the linear motor production process in the existing technology, there are often differences in the consistency between linear motor units, resulting in differences in the vibration feeling experienced by users when the product reaches the hands.

[0049] The present application provides a solution, which first writes an initial waveform file in a capacitive pen, collects the vibration waveform when writing according to the initial waveform file, and then compares and modifies it with the standard waveform, thereby compensating for the inconsistent vibration caused by the differences in linear motor units, and can obtain a more realistic simulation of the actual writing effect based on the characteristics of the motor.

[0050] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a linear motor vibration calibration device that can realize the above functions. The following takes the linear motor vibration calibration device as an example to illustrate this embodiment and the following embodiments.

[0051] Based on this, the present application embodiment provides a linear motor vibration sense calibration method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the linear motor vibration calibration method of the present application.

[0052] In this embodiment, the linear motor vibration calibration method includes steps S10 to S40:

[0053] Step S10: obtaining an initial waveform file of the linear motor driving the capacitive pen to vibrate.

[0054] It should be noted that the initial waveform file may be a file that uses a specific driving waveform to drive the linear motor to simulate a specific vibration effect, such as simulating the writing effect of a pen, pencil, etc. Different from other scenarios where linear motors are used, such as mobile phones, the motor driving waveform is usually not a single-frequency sine wave, but a composite driving waveform containing a wide range of frequency components. Such a driving waveform can more realistically simulate the actual writing effect according to the characteristics of the motor.

[0055] It should be understood that during the vibration of a linear motor, strong energy will be generated in the frequency spectrum from tens of Hz to 20k Hz. The motor calibration method in traditional capacitive pens only calibrates the vibration amount at a specific frequency point, which has limited improvement in the overall motor vibration consistency. If the frequency response curve of a linear motor unit is calibrated as a whole, the algorithm is complex, the requirements for the computing performance of the product hardware are high, and the engineering implementation is difficult.

[0056] Furthermore, in order to simulate the real vibration effect of an active pen, the writing vibration effect of an actual pencil, pen, etc. on real paper can be collected through microphone or accelerometer measurement, and a standard waveform curve for capacitive pen writing can be constructed. The standard waveform curve is written into an array to obtain an initial waveform file for storage.

[0057] Step S20: driving the capacitive pen to vibrate according to the initial driving file, and collecting an actual waveform curve of the vibration of the capacitive pen.

[0058] It should be noted that, similar to the above-mentioned method of acquiring the standard waveform curve, a microphone or accelerometer measurement method can be used to collect the vibration waveform when the capacitive pen uses the initial drive file to write, which is the actual waveform curve.

[0059] Step S30: using the actual waveform curve to compare with the standard waveform curve of the capacitive stylus vibration.

[0060] Step S40: modifying the initial waveform file according to the comparison result to obtain a driving waveform file, and using the driving waveform file to drive the capacitive stylus to vibrate.

[0061] It should be noted that the standard waveform curve is a waveform collected based on the vibration effect of writing with an actual pencil, pen, etc. on real paper. According to the result of comparing the actual waveform curve generated when each linear motor drives the capacitive pen to run with the standard waveform curve, it is possible to determine the value of energy (or amplitude) that the linear motor needs to increase or decrease in a certain frequency domain. Then, the initial waveform file is modified to obtain a driving waveform file, which can be a file of the linear motor driving the capacitive pen to vibrate after consistency calibration.

[0062] It should be understood that after the initial waveform file is modified into a driving waveform file, the vibration effect error generated by driving different linear motors is within a preset difference range, so as to improve the vibration consistency of the active capacitive stylus.

[0063] In this embodiment, the initial waveform file of the linear motor driving the capacitive pen to vibrate is obtained; the capacitive pen is driven to vibrate according to the initial driving file, and the actual waveform curve of the capacitive pen vibration is collected; the actual waveform curve is compared with the standard waveform curve of the capacitive pen vibration; the initial waveform file is modified according to the comparison result to obtain the driving waveform file, and the capacitive pen is driven to vibrate using the driving waveform file. The initial waveform file is first written into the capacitive pen, and the vibration waveform when writing according to the initial waveform file is collected, and then compared and modified with the standard waveform to compensate for the inconsistent vibration feeling due to the difference in linear motor monomers, so that a more realistic simulation of the actual writing effect can be obtained according to the characteristics of the motor.

[0064] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 A flow chart of the second embodiment of the linear motor vibration calibration method of the present application is provided. In step S20, the linear motor vibration calibration method includes:

[0065] Step S201: driving the capacitive stylus to vibrate according to the initial driving file.

[0066] Step S202: collecting actual energy amplitudes corresponding to more than one frequency point within a preset frequency domain.

[0067] It should be noted that a measuring device such as a microphone or an accelerometer can construct an energy distribution curve in response to the vibration of the capacitive pen when writing, that is, obtain the energy amplitude of the capacitive pen at different frequency points. The preset frequency domain range can be a preset frequency domain range (e.g., 0-20kHz) for the linear motor to work. The actual energy amplitude can be the actual energy amplitude at different frequency points generated in response to the initial drive file.

[0068] Step S203: Mapping each of the actual energy amplitudes and the corresponding frequency points to obtain an actual waveform curve in the preset frequency domain range.

[0069] It should be noted that the actual waveform curve may be a curve in which the independent variable is each frequency point in the frequency domain and the dependent variable is the actual energy amplitude corresponding to the frequency point.

[0070] Furthermore, similar to the above-mentioned actual waveform curve, a standard waveform curve written by a capacitive pen can also be collected; the standard energy amplitude of each frequency point within the preset frequency domain range is obtained according to the standard waveform curve; and the actual energy amplitude of each frequency point is compared with the standard energy amplitude.

[0071] Reference Figure 3 , Figure 3 A schematic diagram of a vibration compensation process provided in Embodiment 2 of the linear motor vibration calibration method of the present application. The step S40 further includes:

[0072] Step S301: Obtain the comparison difference between the actual energy amplitude and the standard energy amplitude of each frequency point according to the comparison result.

[0073] It should be noted that the average error can be calculated through multiple vibration measurements to obtain a more accurate relative error result.

[0074] Step S302: obtaining a vibration compensation value according to the comparison difference.

[0075] The calculation formula for the vibration compensation value of each frequency point is as follows:

[0076] ΔS f =(∑di / n) / S*100%

[0077] Among them, ΔS f It represents the vibration compensation value calculated at a specific frequency point, di is the difference between the corresponding actual energy amplitude and the standard energy amplitude for each vibration, n is the number of tests, and S is the absolute value of the standard energy amplitude.

[0078] Step S303: modifying the initial waveform file according to the vibration compensation value to obtain a driving waveform file, and using the driving waveform file to drive the capacitive stylus to vibrate.

[0079] The compensation formula for compensating the initial waveform file to obtain the driving waveform file according to the vibration compensation value is as follows:

[0080] S d1 =(1+ΔS f )*S d

[0081] Among them, S d Indicates the amplitude of the standard driving waveform at the corresponding frequency point, S d1 Indicates the amplitude of the compensated driving waveform at the corresponding frequency point.

[0082] Furthermore, the initial waveform file is modified according to the vibration compensation value until the vibration compensation value of each frequency point is within a preset error range (for example, 3%); the driving waveform file obtained by modifying the initial waveform file with the vibration compensation value at this time is obtained, and the driving waveform file is used to drive the capacitive pen to vibrate.

[0083] It should be understood that the above calculation is only an example. In actual operation, other algorithms, such as the root mean square error method, the correlation coefficient method, etc., can be added to make the calculated error range more accurate, which is not specifically limited here.

[0084] In this embodiment, the capacitive pen is driven to vibrate according to the initial drive file; the actual energy amplitude corresponding to more than one frequency point in the preset frequency domain is collected; each of the actual energy amplitudes and the corresponding frequency points are mapped to obtain the actual waveform curve in the preset frequency domain. The standard waveform curve written by the capacitive pen is collected; the standard energy amplitude of each frequency point in the preset frequency domain is obtained according to the standard waveform curve; the actual energy amplitude of each frequency point is compared with the standard energy amplitude. According to the comparison result, the comparison difference between the actual energy amplitude and the standard energy amplitude of each frequency point is obtained; the vibration compensation value is obtained according to the comparison difference; according to the vibration compensation value, the initial waveform file is modified to obtain the drive waveform file, and the drive waveform file is used to drive the capacitive pen to vibrate. At the same time, the active capacitive pen can be repeatedly calibrated multiple times so that the vibration effect of the active capacitive pen in a specific scenario is highly consistent with the expected standard vibration feel.
