背景技术Background technique
触觉反馈技术是一种通过硬件与软件结合、辅以作用力或振动等动作的触觉反馈机制，能够模拟人的真实触觉体验。触觉反馈技术在手机、汽车、可穿戴设备、游戏设备等电子设备中广泛应用，通过定制独特的触觉反馈效果提升用户体验。Tactile feedback technology is a tactile feedback mechanism that combines hardware and software, supplemented by actions such as force or vibration, and can simulate the real human tactile experience. Tactile feedback technology is widely used in electronic devices such as mobile phones, automobiles, wearable devices, and gaming devices, and the user experience is improved by customizing unique tactile feedback effects.
电子设备中可以设置通过振动效果模拟触觉反馈效果的振动***。一般的，振动***接收到振动信号，基于振动信号产生电机的电压输入信号，使得电机驱动振动***产生振动信号所需的振动效果。基于振动信号不同的振动幅值、不同的振动时长、及不同的振动频率，可以组合出多种多样的触觉反馈效果。但是，受限于电子设备对振动***的电压输出能力以及振动***中电机的性能，有些振动效果很难被振动***实现。The electronic device may be provided with a vibration system that simulates the tactile feedback effect through the vibration effect. Generally, the vibration system receives the vibration signal and generates the voltage input signal of the motor based on the vibration signal, so that the motor drives the vibration system to generate the vibration effect required by the vibration signal. Based on different vibration amplitudes, different vibration durations, and different vibration frequencies of the vibration signal, a variety of tactile feedback effects can be combined. However, limited by the voltage output capability of the electronic equipment to the vibration system and the performance of the motor in the vibration system, some vibration effects are difficult to achieve by the vibration system.
例如，在某些应用场景下，电子设备的振动***接收到的振动信号可能需要振动***在极短的时间内迅速产生较大强度的振动，但是这种需求需要电子设备为振动***提供一个极大的电压才能够实现，而电子设备的电压输出能力是有限的，无法实现振动信号所要求的振动效果。For example, in certain application scenarios, the vibration signal received by the vibration system of an electronic device may require the vibration system to quickly generate a relatively large amount of vibration in a very short period of time. However, this demand requires the electronic device to provide a very high level of vibration for the vibration system. A large voltage can be achieved, but the voltage output capability of electronic devices is limited, and the vibration effect required by the vibration signal cannot be achieved.

现有的实现方案中，电子设备的振动***接收到的振动信号可能需要振动***在极短的时间内迅速产生较大强度的振动，但是需要电子设备为振动***提供一个极大的电压，振动***才能够实现这种需求，而电子设备的电压输出能力是有限的，从而振动***无法实现振动信号所要求的振动效果。In the existing implementation scheme, the vibration signal received by the vibration system of the electronic device may require the vibration system to rapidly generate a relatively large vibration in a very short time, but the electronic device is required to provide a large voltage for the vibration system. The system can only meet this demand, and the voltage output capability of the electronic device is limited, so the vibration system cannot achieve the vibration effect required by the vibration signal.

图3为本申请信号处理方法一个实施例的流程图，如图3所示，该方法可以包括：FIG. 3 is a flowchart of an embodiment of the signal processing method of this application. As shown in FIG. 3, the method may include:
步骤301：接收第一振动信号，从第一振动信号的第一时刻开始截取预设时长的信号作为第二振动信号，第一时刻的相位为预设相位。Step 301: Receive a first vibration signal, intercept a signal of a preset duration from the first moment of the first vibration signal as the second vibration signal, and the phase at the first moment is the preset phase.
其中，第一时刻也即对应着第二振动信号的起始时刻。Among them, the first moment corresponds to the start moment of the second vibration signal.
步骤302：获取第一拼接信号，第一拼接信号终止时刻的相位为预设相位；第一拼接信号是从使用单频正弦波电压信号驱动电机时电机产生的振动响应曲线的初始时刻开始截取至第二时刻的信号，单频正弦波电压信号的频率是电机的谐振频率，幅值是电机所属电子设备的最大输出电压。Step 302: Obtain the first splicing signal, the phase of the termination time of the first splicing signal is the preset phase; the first splicing signal is intercepted from the initial moment of the vibration response curve generated by the motor when the single frequency sine wave voltage signal is used to drive the motor For the signal at the second moment, the frequency of the single-frequency sine wave voltage signal is the resonance frequency of the motor, and the amplitude is the maximum output voltage of the electronic device to which the motor belongs.
步骤303：对第一拼接信号进行幅值缩放，得到第二拼接信号，第二拼接信号终止时刻的幅值与第二振动信号起始时刻的幅值相等。Step 303: Perform amplitude scaling on the first spliced signal to obtain a second spliced signal, and the amplitude of the end time of the second spliced signal is equal to the amplitude of the start time of the second vibration signal.
步骤304：对第二拼接信号和第二振动信号进行拼接，得到目标振动信号。Step 304: splicing the second splicing signal and the second vibration signal to obtain the target vibration signal.
基于以上方法得到的目标振动信号能够在电子设备的电压输出能力范围内，使得振动***快速产生较大强度的振动，从而使得振动***尽量快速的达到第一振动信号所需的振动效果。The target vibration signal obtained based on the above method can be within the range of the voltage output capability of the electronic device, so that the vibration system quickly generates a relatively large vibration, so that the vibration system can achieve the vibration effect required by the first vibration signal as quickly as possible.
图4为本申请信号处理方法另一个实施例的流程图，如图4所示，该方法可以包括：Fig. 4 is a flowchart of another embodiment of the signal processing method of this application. As shown in Fig. 4, the method may include:
步骤401：接收第一振动信号。Step 401: Receive a first vibration signal.
其中，第一振动信号可以由电子设备中需要进行触觉反馈的应用生成，从而触发处理器执行本申请信号处理方法，进行第一振动信号的处理。需要进行触觉反馈的应用可以包括但不限于：游戏、视频等应用。Wherein, the first vibration signal may be generated by an application that requires tactile feedback in the electronic device, thereby triggering the processor to execute the signal processing method of the present application to process the first vibration signal. Applications that require tactile feedback may include, but are not limited to: games, video and other applications.
步骤402：判断电机产生第一振动信号所需电压大于电子设备的最大输出电压时，从第一振动信号的第一时刻开始截取预设时长的信号作为第二振动信号，第一时刻的相位为预设相位。Step 402: When it is determined that the voltage required by the motor to generate the first vibration signal is greater than the maximum output voltage of the electronic device, a signal of a preset duration is intercepted from the first moment of the first vibration signal as the second vibration signal, and the phase at the first moment is Preset phase.
其中，可以将第一振动信号代入预设的振动***机电耦合方程，计算得到第一振动信号对应的电压信号，电压信号的绝对最大值即为上述电机产生第一振动信号所需电压。The first vibration signal can be substituted into the preset electromechanical coupling equation of the vibration system, and the voltage signal corresponding to the first vibration signal can be calculated. The absolute maximum value of the voltage signal is the voltage required by the motor to generate the first vibration signal.
以上述电机是线性电机为例，振动***机电耦合方程可以为：Taking the above-mentioned motor as a linear motor as an example, the electromechanical coupling equation of the vibration system can be:

其中，m为电机动子的质量，c为电机机械阻尼，k为电机弹簧系数，BL为机电耦合系数，R e为电机线圈电阻，L e为电机线圈电感，i为电流，u为电压，x为位移，

为速度，
Figure PCTCN2020132039-appb-000003
为加速度。其中，速度

可以由位移x一次求导得到，加速度
Figure PCTCN2020132039-appb-000005
可以由位移x两次求导得到，电流为中间耦合量i。方程中涉及的电机动子的质量、电机机械阻尼、电机弹簧系数、机电耦合系数、电机线圈电阻、电机线圈电感等参数的数值可以基于电机预先设置，将第一振动信号作为位移x，相应 的，即可以计算得到电压信号u。 Wherein, m is the mass of the motor mover, c is the motor mechanical damping, k for the motor spring coefficient, BL is the electromechanical coupling coefficient, R e is a motor coil resistance, L e is the motor coil inductance, i is the current, u is voltage, x is the displacement,
Figure PCTCN2020132039-appb-000002
Is the speed,
Figure PCTCN2020132039-appb-000003
Is acceleration. Among them, the speed
Figure PCTCN2020132039-appb-000004
It can be derived from the displacement x once, and the acceleration
Figure PCTCN2020132039-appb-000005
It can be derived from the displacement x twice, and the current is the intermediate coupling quantity i. The values of the motor mover mass, motor mechanical damping, motor spring coefficient, electromechanical coupling coefficient, motor coil resistance, motor coil inductance and other parameters involved in the equation can be preset based on the motor, and the first vibration signal is used as the displacement x, corresponding , That is, the voltage signal u can be calculated.
其中，为了便于拼接，第一时刻可以为第一振动信号的波峰对应的时刻，或者波谷对应的时刻，相应的，预设相位可以为第一振动信号的波峰对应的相位、或者波谷对应的相位。可选地，第一时刻可以为第一振动信号第二个波峰对应的时刻。Among them, in order to facilitate splicing, the first moment may be the moment corresponding to the peak of the first vibration signal or the moment corresponding to the trough. Accordingly, the preset phase may be the phase corresponding to the peak of the first vibration signal or the phase corresponding to the trough. . Optionally, the first moment may be a moment corresponding to the second peak of the first vibration signal.
其中，预设时长的具体取值可以在实际应用中自主设定，本申请实施例不作限定，例如，预设时长可以为：从第一振动信号的第一时刻至终止时刻。Wherein, the specific value of the preset duration can be independently set in practical applications, which is not limited in the embodiment of the present application. For example, the preset duration can be from the first moment of the first vibration signal to the termination moment.
一般的，预设时长不能过短，以避免最终得到的目标振动信号过短，振动***无法产生第一振动信号所需要的振动效果。预设时长的最小值与驱动振动***的电机的性能相关，例如电机性能相对较好，则预设时长的最小值可以相对较小，电机性能相对较差，则预设时长的最小值可以相对较大。Generally, the preset duration cannot be too short to avoid that the final target vibration signal is too short, and the vibration system cannot generate the vibration effect required by the first vibration signal. The minimum value of the preset duration is related to the performance of the motor driving the vibration system. For example, if the motor performance is relatively good, the minimum value of the preset duration can be relatively small, and the motor performance is relatively poor, then the minimum value of the preset duration can be relatively Larger.
参见图5A所示，为一种第一振动信号的波形示意图，假设电机产生图5A所示的第一振动信号所需电压大于电子设备的最大输出电压Vmax；则，Refer to FIG. 5A, which is a schematic diagram of the waveform of a first vibration signal. Assuming that the voltage required by the motor to generate the first vibration signal shown in FIG. 5A is greater than the maximum output voltage Vmax of the electronic device; then,
参见图5B所示，可以从第一振动信号的第二个波峰的位置开始截取之后的所有第一振动信号为第二振动信号。As shown in FIG. 5B, all the first vibration signals after being intercepted from the position of the second peak of the first vibration signal are the second vibration signals.
需要说明的是，基于步骤402可知，本申请实施例中的第一振动信号的长度一般不能过短，以使得步骤402中能够从第一振动信号中找到具有预设相位的第一时刻，从而截取到第二振动信号，第一振动信号的长度与第二振动信号的截取规则有关，也即与第一时刻、以及预设相位相关。举例来说，对于图5A所示第一振动信号，假设第一时刻是第一振动信号的第一个波峰对应的时刻，那么，第一时刻为T/4，T是电机的周期，则第一振动信号的长度需要大于T/4，才能截取到第二振动信号；假设第一时刻是第一振动信号的第二个波峰对应的时刻，那么第一时刻为5T/4，则第一振动信号的长度需要大于5T/4，才能截取到第二振动信号。It should be noted that, based on step 402, it can be known that the length of the first vibration signal in the embodiment of the present application generally cannot be too short, so that the first moment with the preset phase can be found from the first vibration signal in step 402, thereby The second vibration signal is intercepted, and the length of the first vibration signal is related to the interception rule of the second vibration signal, that is, it is related to the first moment and the preset phase. For example, for the first vibration signal shown in FIG. 5A, assuming that the first time is the time corresponding to the first peak of the first vibration signal, then the first time is T/4, and T is the period of the motor, then the first time The length of a vibration signal needs to be greater than T/4 to intercept the second vibration signal; assuming that the first time is the time corresponding to the second peak of the first vibration signal, then the first time is 5T/4, then the first vibration The length of the signal needs to be greater than 5T/4 to intercept the second vibration signal.
通过以上的步骤401～步骤403，即得到步骤301中的第二振动信号。Through the above steps 401 to 403, the second vibration signal in step 301 is obtained.
步骤403：获取第一拼接信号，第一拼接信号终止时刻的相位为预设相位；第一拼接信号是从使用单频正弦波电压信号驱动电机时电机产生的振动响应曲线的初始时刻开始截取至第二时刻的信号，单频正弦波电压信号的频率是电机 的谐振频率，幅值是电机所属电子设备的最大输出电压。Step 403: Obtain the first splicing signal. The phase at the end of the first splicing signal is the preset phase; the first splicing signal is intercepted from the initial moment of the vibration response curve generated by the motor when the single-frequency sine wave voltage signal is used to drive the motor. For the signal at the second moment, the frequency of the single-frequency sine wave voltage signal is the resonance frequency of the motor, and the amplitude is the maximum output voltage of the electronic device to which the motor belongs.
在一种可能的实现方式中，第一拼接信号可以预先设置于电子设备中，则本步骤中可以从电子设备中直接获取该第一拼接信号。此时，步骤402中的预设相位需要与电子设备中预先设置的第一拼接信号的终止时刻的相位相同。In a possible implementation manner, the first splicing signal may be preset in the electronic device, and then the first splicing signal may be directly obtained from the electronic device in this step. At this time, the preset phase in step 402 needs to be the same as the phase at the termination time of the first splicing signal preset in the electronic device.
在另一种可能的实现方式中，第一拼接信号可以实时生成。此时，获取第一拼接信号可以包括：In another possible implementation manner, the first splicing signal can be generated in real time. At this time, acquiring the first splicing signal may include:
计算使用单频正弦波电压信号驱动电机时电机产生的振动响应曲线；单频正弦波电压信号的频率是电机的谐振频率，幅值是电机所属电子设备的最大输出电压；Calculate the vibration response curve of the motor when a single-frequency sine wave voltage signal is used to drive the motor; the frequency of the single-frequency sine wave voltage signal is the resonance frequency of the motor, and the amplitude is the maximum output voltage of the electronic equipment to which the motor belongs;
根据第一振动信号中第一时刻对应的相位，确定振动响应曲线中的第二时刻，第二时刻对应的相位与第一时刻对应的相位相同；Determine the second time in the vibration response curve according to the phase corresponding to the first time in the first vibration signal, and the phase corresponding to the second time is the same as the phase corresponding to the first time;
截取振动响应曲线中从初始时刻至第二时刻的信号，作为第一拼接信号。The signal from the initial moment to the second moment in the vibration response curve is intercepted and used as the first splicing signal.
其中，如果第一时刻是第一振动信号的波峰对应的时刻，那么第二时刻也是振动响应曲线中的波峰对应的时刻；可选地，第二时刻可以是振动响应曲线中第二个波峰对应的时刻；或者，Among them, if the first moment is the moment corresponding to the peak of the first vibration signal, then the second moment is also the moment corresponding to the peak in the vibration response curve; optionally, the second moment may be the second peak corresponding to the vibration response curve. The moment; or,
如果第一时刻是第一振动信号的波谷对应的时刻，那么第二时刻也是振动响应曲线的波谷对应的时刻。If the first moment is the moment corresponding to the trough of the first vibration signal, then the second moment is also the moment corresponding to the trough of the vibration response curve.
对步骤403的实现举例说明：参见图5C所示，实线和虚线构成的信号为振动响应曲线，振动响应曲线中的实线部分为截取的拼接信号，拼接信号的终止时刻对应振动响应曲线的第二时刻，第二时刻为振动响应曲线中第二个波峰对应的时刻。An example of the implementation of step 403: see Figure 5C, the signal formed by the solid line and the dashed line is the vibration response curve, the solid line part of the vibration response curve is the intercepted splicing signal, and the termination time of the splicing signal corresponds to the vibration response curve. The second moment is the moment corresponding to the second peak in the vibration response curve.
步骤404：对第一拼接信号进行幅值缩放，得到第二拼接信号，第二拼接信号终止时刻的幅值与第二振动信号起始时刻的幅值相等。Step 404: Perform amplitude scaling on the first spliced signal to obtain a second spliced signal, and the amplitude of the end time of the second spliced signal is equal to the amplitude of the start time of the second vibration signal.
步骤405：对第二拼接信号和第二振动信号进行拼接，得到目标振动信号。Step 405: Splicing the second splicing signal and the second vibration signal to obtain the target vibration signal.
其中，将第二拼接信号放置于第二振动信号之前进行拼接。Wherein, the second splicing signal is placed before the second vibration signal for splicing.
延续之前的举例，参见图5D所示，长度较短的信号为第一拼接信号，第一拼接信号缩小幅值，使得得到的第二拼接信号的终止时刻的幅值与第二振动信号起始时刻的幅值相同，第二拼接信号与第二振动信号拼接后得到的信号即为 目标振动信号。Continuing the previous example, referring to Figure 5D, the signal with a shorter length is the first splicing signal, and the first splicing signal is reduced in amplitude, so that the obtained second splicing signal has the same amplitude at the end time of the second vibration signal. The amplitudes at the moments are the same, and the signal obtained after the second splicing signal and the second vibration signal are spliced together is the target vibration signal.
得到目标振动信号后，可以根据目标振动信号计算得到电机的电压输入信号，将电压输入信号输入至电机，即可使得电机产生目标振动信号，从而使得电机能够在电子设备的电压输出能力范围内，快速产生较大强度的振动，也即使得振动***在电子设备的电压输出能力范围内尽量快速的达到第一振动信号所需的振动效果。After the target vibration signal is obtained, the voltage input signal of the motor can be calculated according to the target vibration signal, and the voltage input signal is input to the motor to make the motor generate the target vibration signal, so that the motor can be within the voltage output capability of the electronic device. The rapid generation of large-intensity vibration means that the vibration system can achieve the vibration effect required by the first vibration signal as quickly as possible within the voltage output capability of the electronic device.
