Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
At present, be provided with linear motor in the electronic equipment, utilize linear motor to take turns to and stop suddenly and reach the effect of vibrations electronic equipment to can improve user experience.
In practical application, the electronic device is provided with a sliding bar in a user interface, and a user adjusts the vibration strength of the linear motor by moving the position of the sliding block on the sliding bar, namely when the sliding block moves towards one direction, the input voltage of the linear motor can be increased, and at the moment, the vibration strength of the linear motor is increased; when moving in the other direction, the input voltage of the linear motor can be reduced, and the vibration intensity of the linear motor is weakened.
However, in the related art, only the magnitude of the input voltage is adjusted, and when the vibration intensity is weakened to a certain degree, the vibration cycle is not changed, so that the vibration sense is dragged, and the user experience is affected.
In order to solve the above technical problem, an embodiment of the present disclosure provides a method for controlling vibration sensation of a motor, and the method includes adjusting vibration intensity of the motor by using input waveforms having different oscillation periods. Therefore, the vibration sensing effect of the motor can be controlled by the difference of the vibration starting period number.
Fig. 1 is a flowchart illustrating a motor vibration sense control method according to an exemplary embodiment, which may be suitable for an electronic device provided with a motor. The motor may be one of a linear motor, a voice coil motor, and a vibration motor, which is not limited herein. Referring to fig. 1, a method for controlling a vibration sensation of a motor includes steps 11 to 13, wherein:
in step 11, a target vibration intensity of the motor is acquired.
In this embodiment, a user interface may be disposed in the electronic device, and the user interface includes a slider, so that a user may move a slider on the slider to adjust the vibration intensity of the motor. Referring to FIG. 2, in step 21, the electronic device may detect the relative position of a slider on a slider bar within a user interface. For example, the maximum length of the slide bar corresponds to the maximum vibration intensity of the motor, and the ratio of the distance between the slide block and one end of the slide bar to the maximum length can be used as the relative position of the slide block. In step 22, the electronic device may obtain a preset correspondence relationship between the relative position and the vibration intensity, and obtain the vibration intensity corresponding to the relative position, and use the vibration intensity as the target vibration intensity of the motor. For example, the maximum length of the slider corresponds to a vibration intensity of 0.6G, and assuming that the relative position of the slider is 67%, the vibration intensity corresponding to the relative position can be obtained to be 0.4G.
In practical application, a user interface may be arranged in the electronic device, the user interface may include an input box, and a user may directly or indirectly input the target vibration intensity in the input box according to the prompt information, and the corresponding scheme falls within the protection scope of the present disclosure.
In step 12, selecting a candidate input waveform with vibration intensity matching the target vibration intensity from a plurality of candidate input waveforms according to the target vibration intensity; the plurality of candidate input waveforms have different start periods.
In this embodiment, a plurality of candidate input waveforms may be preset in the electronic device. Each candidate input waveform in the plurality of candidate input waveforms comprises a preset number of start-oscillation periods and a stop-oscillation period matched with the start-oscillation periods; the number of start-up periods of different candidate input waveforms is different. It can be understood that, in the case that the voltage values are the same, the greater the number of the oscillation starting periods, the greater the vibration intensity of the motor, and thus the vibration intensities of the motors corresponding to the plurality of candidate input waveforms are also different. Therefore, a preset relation between the vibration intensity and the number of the vibration starting periods can be preset in the electronic equipment. In one example, each candidate input waveform may correspond to a vibration intensity range, for example, 3 start periods correspond to a vibration intensity range of [0.6G, 0.4G ], and 2 start periods correspond to [0.4G, 0.2G ]. Therefore, a coincidence intensity exists in the vibration intensity ranges of two candidate input waveforms with adjacent oscillation starting periods, for example, the vibration intensity ranges of 3 oscillation starting periods and 2 oscillation starting periods can correspond to a coincidence intensity of 0.4G, so that sudden jump of the vibration intensity is avoided.
In this embodiment, the slider may be divided into a plurality of regions, and each region corresponds to one candidate input waveform. In this way, the electronic device may determine a candidate input waveform based on the region where the slider is located, and use the candidate input waveform as a candidate input waveform matching the target vibration intensity.
In this embodiment, referring to fig. 3, in step 31, a preset relationship between the vibration intensity and the number of the start vibration cycles may be obtained in the electronic device, and the number (N) of the start vibration cycles in the input waveform is obtained according to the target vibration intensity, that is, when the motor is driven to vibrate by how many start vibration cycles, the vibration intensity of the motor can reach the target vibration intensity. In step 32, the electronic device may select a candidate input waveform with N oscillation starting periods from a plurality of candidate input waveforms according to the number of oscillation starting periods, and use the candidate initial input waveform as the candidate input waveform with the oscillation intensity matching the target oscillation intensity. That is, the candidate input waveform has N oscillation start cycles, and the vibration intensity of the motor can be matched with the target vibration intensity, where matching means that the vibration intensity is the same as the target vibration intensity or the difference between the two is within a set range.
In step 13, the motor is driven to vibrate based on the candidate input waveform.
In this embodiment, the electronic device may drive the motor to vibrate based on the candidate input waveform, so that the vibration intensity of the motor matches the target vibration intensity, and is particularly suitable for a scenario in which the target vibration intensity is an end point of the vibration intensity range corresponding to the candidate input waveform.
It should be noted that, since there is an important vibration intensity in two candidate input waveforms with adjacent numbers of start-up periods, the selection may be as follows: one candidate input waveform is randomly selected, and the candidate input waveform with the smaller number of oscillation starting periods is selected.
In an embodiment, referring to fig. 4, in step 41, the electronic device may further compare the target vibration intensity with the vibration intensity corresponding to the candidate input waveform, and adjust the voltage value of the candidate input waveform based on the target vibration intensity to obtain the target input waveform when the target vibration intensity is different from the vibration intensity corresponding to the candidate input waveform (i.e., the difference between the target vibration intensity and the vibration intensity exceeds the set range). In step 42, the motor is driven to vibrate based on the target input waveform, so that the vibration intensity of the motor is the target vibration intensity. For example, when the vibration intensity exceeds the target vibration intensity, the voltage value may be increased by a set step size; when the vibration intensity is smaller than the target vibration intensity, the voltage value can be reduced according to the set step length until the vibration intensity of the motor is the same as the target vibration intensity, so that the target input waveform is obtained. In this way, in the subsequent process, if the user operates the electronic device, for example, clicks a button, the electronic device may drive the motor to vibrate according to the target input waveform, so that the motor vibrates to the target vibration strength.
To this end, in the embodiment of the present disclosure, the target vibration intensity of the motor may be acquired; selecting a candidate input waveform with the vibration intensity matched with the target vibration intensity from a plurality of candidate input waveforms according to the target vibration intensity; the plurality of candidate input waveforms have different start periods; driving the motor to vibrate based on the candidate input waveform. Therefore, the oscillation starting period of the input waveform can be adjusted by selecting the input waveform in the embodiment, the effect of controlling the oscillation intensity and the oscillation period is achieved, and the accuracy of adjusting the oscillation intensity is improved.
A motor vibration sense control method is described below with reference to a specific scenario. FIG. 5(a) provides a candidate input waveform 1, wherein the candidate input waveform 1 comprises 2 start periods (about 0-230 ms) and 1.5 stop periods (230-410 ms), and the output waveform of the motor is shown in FIG. 5 (b). Fig. 6(a) provides a candidate input waveform 2, the candidate input waveform 2 includes 3 start periods (about 0-350 ms) and 3 stop periods (about 350-640 ms), and the motor output waveform is as shown in fig. 6 (b).
It should be noted that, in the process of reversely driving the motor in the vibration-off period, the motor may be reversely vibrated, so that a vibration-off period is further set for 410-550 ms in fig. 5(a), and 0.5 vibration-off periods is further set for 640-700 ms in fig. 6(a), so that the effect of quickly stopping vibration of the motor can be set according to a specific scene, which is not limited herein.
In the default state, the vibration intensity of the motor is the maximum vibration intensity, such as 0.6G, and the motor is driven to vibrate by using the input waveform 2. During use, the user finds that the vibration intensity is too great, and therefore finds the control slider for the motor tremoly through the menu. The user can press the slider and move the slider closer to the starting point (position). The electronic equipment can acquire the relative position of the sliding block and determine the target vibration strength. Assuming that the target vibration intensity exceeds 0.4G (e.g. 0.45G), the electronic device still drives the motor with the input waveform 2, but the voltage value of the input waveform 2 needs to be adjusted to make the current vibration intensity reach 0.45G.
Assuming that the target vibration intensity is equal to 0.4G, either one of the input waveform 2 and the input waveform 1 may be selected. Alternatively, the start period of the two candidate input waveforms may be compared, for example, in consideration of the fact that the start period of the input waveform 1 is smaller than the start period of the input waveform 2, the input waveform 1 may be selected in the present embodiment, so as to shorten the vibration period.
Assuming that the target vibration intensity is less than 0.4G (e.g. 0.35G), the electronic device may switch from the current input waveform 2 to the input waveform 1 to drive the motor, and since the number of the start periods of the input waveform 1 is less than the number of the start periods of the input waveform 2, the vibration intensity of the motor may become small, and then adjust the voltage value of the input waveform 1, so that the vibration intensity of the motor is equal to or close to the target vibration intensity.
In other words, referring to FIG. 7, as the slider moves from right to left, the relative position of the slider may change from 100% to 1%. The input waveform 2 is used to drive the motor when the vibration intensity is between 100% and 50% (namely the target vibration intensity is more than 0.4G), and the input waveform 1 is used to drive the motor when the vibration intensity is between 50% and 1% (namely the target vibration intensity is less than 0.4G). The effect of controlling the vibration sense of the motor is achieved by different input waveforms having different number of oscillation starting periods, and if the vibration intensity of the motor corresponding to the input waveforms is not matched with the target vibration intensity, the input waveforms can be made to be the same by adjusting the voltage values of the input waveforms.
