[0043] <Method Embodiment>
[0044] The present disclosure provides a driving method for a vibration exciter. Figure 1 is a flowchart of a driving method for a vibration exciter according to an embodiment of the present disclosure. As Figure 1 shown, the method includes steps S1100 to S1300 as follows:
[0045] Step S1100, determining a target acting force that the vibration exciter needs to generate.
[0046] The target acting force in this embodiment can be set according to the installation angle of the vibration exciter in the electronic device, can also be set according to the vibration scenario of the vibration device, or can also be set according to the actual needs of the user, and is not limited herein.
[0047] In this embodiment, the direction of the target acting force can be parallel to the vibration direction of the vibration exciter. For example, the direction of the target acting force can be the forward vibration direction of the vibration exciter or the reverse vibration direction of the vibration exciter.
[0048] Step S1200, adjusting the duty cycle of the first driving signal according to the target acting force to obtain a second driving signal; wherein, the first driving signal is a signal that enables the vibration exciter to generate positive and negative symmetric vibrations.
[0049] The duty cycle of this embodiment can be the ratio of the duration of the positive half-cycle of the corresponding drive signal to the period duration of the drive signal, or the ratio of the duration of the negative half-cycle of the corresponding drive signal to the period duration of the drive signal, or the ratio of the duration of the positive half-cycle of the corresponding drive signal to the duration of the negative half-cycle of the drive signal.
[0050] In some embodiments, the first duration of the positive half-cycle of the first drive signal is equal to the first duration of the negative half-cycle of the first drive signal.
[0051] In some embodiments, the first drive signal can be a signal that is symmetric about the positive and negative time axes. Specifically, within one period, the waveform of the first drive signal above and below the time axis has the same shape, only with opposite signs. Flipping the waveform above the time axis along the time axis can completely coincide with the waveform below.
[0052] In some embodiments, the first drive signal is any one of a sine wave signal, a cosine wave signal, a rectangular wave signal, and a square wave signal.
[0053] In some embodiments, the period duration of the first drive signal is equal to the period duration of the second drive signal.
[0054] In some embodiments, the duty cycle of the first drive signal can be adjusted according to the direction of the target acting force to obtain the second drive signal.
[0055] Specifically, when the direction of the target acting force is the negative vibration direction, the duty cycle of the first drive signal can be increased; when the direction of the target acting force is the positive vibration direction, the duty cycle of the first drive signal can be decreased.
[0056] In this embodiment, the way to adjust the duty cycle can be to adjust the duty cycle according to a set step size. For example, when the duty cycle of the first drive signal is 50% and the set step size is 20%, increasing the duty cycle of the first drive signal can result in a duty cycle of 70% for the obtained second drive signal; decreasing the duty cycle of the first drive signal can result in a duty cycle of 30% for the obtained second drive signal.
[0057] In some embodiments, adjusting the duty cycle of the first drive signal according to the target acting force to obtain the second drive signal includes: determining a target duty cycle that matches the target acting force; adjusting the duty cycle of the first drive signal to the target duty cycle to obtain the second drive signal.
[0058] In this embodiment, first mapping data reflecting the mapping relationship between the acting force and the duty cycle can be preset; according to the target acting force and the first mapping data, the duty cycle corresponding to the target acting force is obtained as the target duty cycle.
[0059] The first mapping data may be a first mapping function, a first look-up table, etc., which is not limited herein.
[0060] For the first mapping function, the dependent variable of the first mapping function is the duty cycle, and the independent variable is the acting force. In this way, by substituting the target acting force into the first mapping function, the duty cycle corresponding to the target acting force can be obtained as the target duty cycle.
[0061] For the first look-up table, the duty cycle corresponding to the target acting force can be found in the first look-up table as the target duty cycle. If the target acting force cannot be directly found in the first look-up table, two adjacent values to the target acting force can be found, and based on these two values and the duty cycles respectively corresponding to these two values, the duty cycle corresponding to the target acting force can be obtained by interpolation as the target duty cycle.
[0062] In this embodiment, when the direction of the target acting force is the positive vibration direction of the vibration exciter, the target acting force can be a positive number; when the direction of the target acting force is the negative vibration direction of the vibration exciter, the target acting force can be a negative number.
[0063] In some embodiments, determining the target duty cycle matching the target acting force includes: determining the duty cycle adjustment amount matching the target acting force, and obtaining the target duty cycle based on the duty cycle and the duty cycle of the first drive signal.
[0064] In this embodiment, second mapping data reflecting the mapping relationship between the acting force and the duty cycle adjustment amount can be preset; based on the target acting force and the second mapping data, the duty cycle adjustment amount corresponding to the target acting force can be obtained.
[0065] The second mapping data may be a second mapping function, a second look-up table, etc., which is not limited herein.
[0066] For the second mapping function, the dependent variable of the second mapping function is the duty cycle adjustment amount, and the independent variable is the acting force. In this way, by substituting the target acting force into the second mapping function, the duty cycle adjustment amount corresponding to the target acting force can be obtained.
[0067] For the second look-up table, the duty cycle adjustment amount corresponding to the target acting force can be found in the second look-up table. If the target acting force cannot be directly found in the second look-up table, two adjacent values to the target acting force can be found, and based on these two values and the duty cycle adjustment amounts respectively corresponding to these two values, the duty cycle adjustment amount corresponding to the target acting force can be obtained by interpolation.
[0068] In this embodiment, when the direction of the target acting force is the positive vibration direction of the vibration exciter, the target acting force can be a positive number; when the direction of the target acting force is the negative vibration direction of the vibration exciter, the target acting force can be a negative number.
[0069] In this embodiment, the duty cycle adjustment amount can be a positive number or a negative number.
[0070] According to the duty cycle and the duty cycle of the first driving signal, the target duty cycle can be obtained by determining the sum of the duty cycle of the first driving signal and the duty cycle adjustment amount as the target duty cycle.
[0071] Through this embodiment, a target duty cycle matching the target acting force can be obtained, so that the second driving signal obtained according to the target duty cycle can drive the vibration exciter to generate the target acting force, achieving a heterophase vibration effect.
[0072] In some embodiments, adjusting the first driving signal to the second driving signal according to the target duty cycle includes: obtaining the second duration of the positive half-cycle and the second duration of the negative half-cycle according to the target duty cycle and the period duration of the first driving signal; adjusting the first driving signal according to the second duration of the positive half-cycle and the second duration of the negative half-cycle to obtain the second driving signal.
[0073] Specifically, the duration of the positive half-cycle of the adjusted second driving signal is the second duration of the positive half-cycle, and the duration of the negative half-cycle of the second driving signal is the second duration of the negative half-cycle.
[0074] In this embodiment, the first driving signal and the second driving signal can both be periodic signals. Then, it can be to adjust the waveform within any one period of the first driving signal and then adjust the waveforms within other periods to be the same as the waveform within this period; it can also be to adjust the waveforms within each period of the first driving signal simultaneously, which is not limited here.
[0075] In some embodiments, adjusting the first driving signal according to the second duration of the positive half-cycle and the second duration of the negative half-cycle of the second driving signal includes: when the first duration of any half-cycle is greater than the second duration of any half-cycle, compressing the waveform of any half-cycle of the first driving signal according to the second duration of any half-cycle; or, when the first duration of any half-cycle is less than the second duration of any half-cycle, stretching the waveform of any half-cycle of the first driving signal according to the second duration of any half-cycle; where any half-cycle is the positive half-cycle or the negative half-cycle.
[0076] Specifically, when the first duration of the positive half-cycle of the first driving signal is greater than the second duration of the positive half-cycle, the waveform of the positive half-cycle of the first driving signal is compressed so that the duration of the compressed waveform of the positive half-cycle is the second duration of the positive half-cycle. Correspondingly, when the first duration of the negative half-cycle of the first driving signal is greater than the second duration of the negative half-cycle, the waveform of the negative half-cycle of the first driving signal is compressed so that the duration of the compressed waveform of the negative half-cycle is the second duration of the negative half-cycle.
[0077] Furthermore, when the first duration of the positive half-cycle of the first driving signal is less than the second duration of the positive half-cycle, the waveform of the positive half-cycle of the first driving signal is stretched so that the duration of the compressed waveform of the positive half-cycle is the second duration of the positive half-cycle. Correspondingly, when the first duration of the negative half-cycle of the first driving signal is less than the second duration of the negative half-cycle, the waveform of the negative half-cycle of the first driving signal is stretched so that the duration of the compressed waveform of the negative half-cycle is the second duration of the negative half-cycle.
[0078] In an embodiment where the first driving signal is a sine wave, after stretching the waveform of the positive half-cycle of the first driving signal and compressing the waveform of the negative half-cycle of the first driving signal, the obtained second driving signal can be as shown in Figure 2 Waveform 1; after compressing the waveform of the positive half-cycle of the first driving signal and stretching the waveform of the negative half-cycle of the first driving signal, the obtained second driving signal can be as shown in Figure 2 Waveform 2.
[0079] In an embodiment where the first driving signal is a square wave, after stretching the waveform of the positive half-cycle of the first driving signal and compressing the waveform of the negative half-cycle of the first driving signal, the obtained second driving signal can be as shown in Figure 3 Waveform 3; after compressing the waveform of the positive half-cycle of the first driving signal and stretching the waveform of the negative half-cycle of the first driving signal, the obtained second driving signal can be as shown in Figure 3 Waveform 4.
[0080] Through this embodiment, by adjusting the first driving signal to the second driving signal, the second driving signal can drive the vibration exciter to generate a target acting force, achieving a heterophase vibration effect.
[0081] Step S1300, drive the vibration exciter according to the second driving signal so that the vibration exciter generates a target acting force.
[0082] In this embodiment, when the ratio of the duration of the positive half - cycle to the period duration in the second driving signal is 30%, the waveform of the acceleration generated by driving the vibration exciter to vibrate can be as shown in Figure 4 ; when the ratio of the duration of the positive half - cycle to the period duration in the second driving signal is 70%, the waveform of the acceleration generated by driving the vibration exciter to vibrate can be as shown in Figure 5 .
[0083] In some embodiments, when adjusting the duty cycle, the resonance effect of the oscillator of the vibration exciter will first increase and then decrease, resulting in the force generated by the vibration exciter increasing first and then decreasing. That is, when the duty cycle is near the median value of 0 to 50% and 50% to 100% (such as 25% or 75%), the vibration exciter can generate the maximum force more easily.
[0084] Through the embodiments of the present disclosure, by adjusting the duty cycle of the first driving signal according to the target force required to be generated by the vibration exciter to obtain the second driving signal, and then driving the vibration exciter according to the second driving signal, the vibration exciter can generate the target force and achieve the out - of - phase vibration effect. In addition, in this embodiment, the out - of - phase vibration effect can be generated by driving only one vibration exciter with the second driving signal, which can reduce the number of vibration exciters required to be set in the electronic device and reduce the hardware cost of the electronic device.
