Description

Technical Field

[0001] This disclosure relates to the field of vibration motor technology, and more specifically, to a vibration control method, apparatus, and electronic device. Background Technology

[0002] With the rapid development of mobile communication technology and smart terminal technology, smartphones have become an indispensable core electronic device in people's daily lives, work, and social interactions. In order to improve the user interaction experience and the effectiveness of information reminders, haptic feedback has become one of the standard features of smartphones, and the vibration motor, as the core actuator to achieve this function, directly determines the quality of haptic feedback.

[0003] Currently, smartphones commonly use vibration motors to provide haptic feedback. Common types of vibration motors include eccentric rotor motors (ERM) and linear motors (LRA). In scenarios such as incoming calls, receiving messages, typing, touch operation, and gaming, these vibration motors generate vibrations through the mechanical movement of internal moving parts, which are then transmitted to the phone's body and ultimately perceived by the user to achieve a haptic feedback effect.

[0004] However, in actual use, vibration motors often generate high-frequency vibrations during high-frequency vibration. These vibrations typically manifest as a high-pitched sound, a springy sound, or other irregular high-frequency noise. Analysis shows that the generation of these high-frequency vibrations is mainly related to factors such as the motor's structural design, the resonance effect between the vibration frequency and the phone's body, the motor's mounting gap, and the fixing method. The frequency range is usually within the range where the human ear is most sensitive, and it is highly identifiable when propagating in a quiet environment.

[0005] The aforementioned high-frequency vibrations can cause auditory discomfort and noise interference, severely impacting the user experience. Summary of the Invention

[0030] <Method Implementation> This disclosure provides a vibration control method, which can be implemented by an electronic device. Specifically, the vibration control method can be implemented by, for example... Figure 1 The electronic device 1000 shown is implemented.

[0031] Figure 2 This is a flowchart of a vibration control method according to an embodiment of the present disclosure.

[0032] like Figure 2 As shown, the method includes the following steps S2100 to S2300: Step S2100: Obtain a vibration signal that matches the current vibration scenario.

[0033] In this embodiment, the method steps of this embodiment are performed when vibration feedback from an electronic device is required.

[0034] The vibration scenarios in this embodiment may include any one of the following: incoming call reminder, message reminder, typing input, touch operation, and game scenario.

[0035] In some embodiments, a matching vibration signal can be pre-set for each vibration scenario. Under any vibration scenario, the motor can be driven to vibrate according to the vibration signal matching the vibration scenario, so that the electronic device generates vibration feedback matching the vibration scenario.

[0036] In some embodiments, vibration parameters that match each vibration scenario can be preset in advance. Under any vibration scenario, a vibration signal that matches the vibration scenario can be generated according to the vibration parameters that match the vibration scenario, and the motor can be driven to vibrate according to the vibration signal, so that the electronic device generates vibration feedback that matches the vibration scenario.

[0037] Step S2200: Generate a masking signal that matches the vibration signal. The masking signal is used to mask the vibration noise generated by the motor under the drive of the vibration signal.

[0038] When two or more sounds exist simultaneously, one sound may audibly mask another (or other) sound; this phenomenon is called the "masking effect." In this embodiment, the first sound generated by the masking signal driving the motor can audibly mask the second sound generated by the driving signal driving the motor.

[0039] In this embodiment, the closer the frequencies of the first and second sounds are, the greater the masking effect of the first sound on the second sound. The masking effect of the first sound on the second sound is greatest when the frequencies of the first and second sounds are the same. In terms of time, the closer the first sound is to the second sound, the greater the masking effect of the first sound on the second sound, and the latter masking effect is greater than the former masking effect.

[0040] When the first sound is a polyphony composed of multiple sounds, the timbre of the second sound will change because each sound has a different masking value for the second sound.

[0041] In some embodiments, low-frequency sounds significantly mask high-frequency sounds, while high-frequency sounds have a very small masking effect on low-frequency sounds. Therefore, the masking signal can be a low-frequency signal.

[0042] Furthermore, the masking effect of monophonic hearing is greater than that of binaural hearing. Moreover, increasing the sound pressure level of the first sound can broaden the frequency range of masking.

[0043] In some embodiments, generating a masking signal that matches the vibration signal includes: acquiring a target frequency band and a target amplitude; and generating a masking signal based on the target frequency band and the target amplitude.

[0044] In this embodiment, the target frequency band can be a frequency band or a single frequency.

[0045] In some embodiments, the target frequency band may be a fixed value pre-set according to the performance of the motor in the electronic device. For example, the target frequency may be 50-200Hz.

[0046] In some embodiments, obtaining a target frequency band includes: obtaining a first correspondence between a vibration scene and a frequency band; and determining a frequency band corresponding to the current vibration scene based on the first correspondence, as the target frequency band.

[0047] In this embodiment, a corresponding frequency band can be pre-defined for each vibration scenario, and a first correspondence can be established. For example, the frequency band corresponding to the typing input scenario can be 80-150Hz, which can balance the masking effect of the masking signal and the clarity of the tactile feedback generated by the vibration signal. As another example, the frequency band corresponding to the incoming call reminder or message reminder scenario can be 50-200Hz, which can improve the masking effect of the masking signal.

[0048] In some embodiments, the target amplitude may be a fixed value pre-set based on the performance of the motor in the electronic device. For example, the target amplitude may be 1V.

[0049] In some embodiments, obtaining the target amplitude may include: obtaining a second correspondence between vibration scenarios and amplitudes; and determining the amplitude corresponding to the current vibration scenario based on the second correspondence as the target amplitude.

[0050] In this embodiment, a corresponding amplitude can be pre-set for each vibration scenario, and a first correspondence can be established. For example, the amplitude corresponding to the typing input scenario could be 1V, which can balance the masking effect of the masking signal and the clarity of the tactile feedback generated by the vibration signal. As another example, the amplitude corresponding to the incoming call reminder scenario or message reminder scenario could be 1.2V, which can improve the masking effect of the masking signal.

[0051] In some embodiments, the method further includes: acquiring ambient noise signals via a microphone of an electronic device; and adjusting a target amplitude based on the noise signals.

[0052] Specifically, the target amplitude obtained according to any of the foregoing embodiments can be adjusted based on the environmental noise level represented by the noise signal.

[0053] In some embodiments, adjusting the target amplitude based on the noise signal includes: determining a target adjustment ratio corresponding to the amplitude of the noise signal; and adjusting the target amplitude according to the target adjustment ratio.

[0054] In this embodiment, a first mapping data reflecting the mapping relationship between amplitude and adjustment ratio can be preset according to the masking effect curve (such as the equal loudness curve); based on the amplitude of the noise signal and the first mapping data, the adjustment ratio corresponding to the amplitude of the noise signal is obtained as the target adjustment ratio.

[0055] The first mapping data can be the first mapping function, or the first lookup table, etc., and is not limited here.

[0056] For the first mapping function, the dependent variable is the adjustment ratio and the independent variable is the amplitude. Thus, by substituting the amplitude of the noise signal into the first mapping function, the adjustment ratio corresponding to the amplitude of the noise signal can be obtained as the target adjustment ratio.

[0057] For the first lookup table, the adjustment ratio corresponding to the amplitude of the noise signal can be found in the first lookup table as the target adjustment ratio. If the amplitude of the noise signal cannot be found directly in the first lookup table, two values ​​adjacent to the amplitude can be found, and based on these two values ​​and the adjustment ratios corresponding to these two values, an interpolation method can be used to obtain the adjustment ratio corresponding to the amplitude as the target adjustment ratio.

[0058] In some embodiments, adjusting the target amplitude based on the noise signal includes: determining the current ambient noise level based on the noise signal; adjusting the target amplitude according to a target adjustment ratio corresponding to the current ambient noise level; and adjusting the target amplitude according to the target adjustment ratio.

[0059] In this embodiment, multiple environmental noise levels and corresponding adjustment ratios for each level can be pre-set according to the application scenario or specific requirements. The adjustment ratio for lower environmental noise levels is greater than the adjustment ratio for higher environmental noise levels.

[0060] For example, multiple environmental noise levels can include less than 30 dB, greater than or equal to 30 dB and less than or equal to 60 dB, and greater than 60 dB. The adjustment ratio corresponding to less than 30 dB is 120%, the adjustment ratio corresponding to greater than or equal to 30 dB and less than or equal to 60 dB is 100%, and the adjustment ratio corresponding to greater than 60 dB is 50%.

[0061] In this embodiment, a second mapping data reflecting the mapping relationship between the environmental noise level and the adjustment ratio can be preset; based on the current environmental noise level and the second mapping data, the adjustment ratio corresponding to the current environmental noise level is obtained as the target adjustment ratio.

[0062] The second mapping data can be a second mapping function, a second lookup table, etc., and is not limited here.

[0063] For the second mapping function, the dependent variable is the adjustment ratio and the independent variable is the environmental noise level. Thus, by substituting the current environmental noise level into the second mapping function, the adjustment ratio corresponding to the current environmental noise level can be obtained as the target adjustment ratio.

[0064] For the second comparison table, you can find the adjustment ratio corresponding to the current environmental noise level in the second comparison table as the target adjustment ratio.

[0065] This embodiment dynamically adjusts the target amplitude used to generate the masking signal in conjunction with ambient noise, which can enhance the masking effect of the masking signal in a quiet environment and reduce the power consumption of electronic devices in a noisy environment.

[0066] In some embodiments, the masking signal may be a pink noise signal.

[0067] Step S2300: Drive the motor to vibrate according to the vibration signal and the masking signal; wherein the duration of the vibration signal and the masking signal is the same.

[0068] In this embodiment, the motor vibration is driven based on the vibration signal and the masking signal. This can be achieved by providing both the vibration signal and the masking signal to the motor, that is, by superimposing the vibration signal and the masking signal to obtain a superimposed signal, and then driving the motor vibration based on the superimposed signal.

[0069] In this embodiment, the vibration signal and the masking signal have the same duration. The vibration signal and the masking signal can be provided to the motor at the same time, and the supply of the vibration signal and the masking signal to the motor can be stopped at the same time, so that the vibration signal and the masking signal drive the motor to vibrate simultaneously.

[0070] In one example, the vibration spectrum f1 of the acoustic signal generated by the motor under the drive of the vibration signal, and the vibration spectrum f2 of the acoustic signal generated by the motor under the drive of the vibration signal and the masking signal, can be as follows: Figure 3 As shown, the horizontal axis represents frequency and the vertical axis represents amplitude.

[0071] according to Figure 3 It can be seen that the acoustic signal generated by the motor driven by the vibration signal and the masking signal increases in the low-frequency short spectrum, making the vibration sound to the user as if it were masked by low-frequency noise, and the vibration sound is significantly reduced. Moreover, after adding the masking signal, the spectrum of the acoustic signal generated by the motor does not decrease in the high-frequency range, but rather utilizes the acoustic masking effect of the human ear, using the increase of the low-frequency masking signal to mask the high-frequency noise generated by the motor.

[0072] In this embodiment, a masking signal is injected into the vibration signal to drive the motor vibration, which can reduce the vibration noise generated by the motor under the drive of the vibration signal, and does not require changes to the motor structure, thus reducing optimization costs.

[0073] <Device Embodiment> This embodiment provides a vibration control device, such as... Figure 4 As shown, the vibration control device 4000 may include a vibration signal acquisition module 4100, a masking signal generation module 4200, and a motor drive module 4300.

[0074] The vibration signal acquisition module 4100 is used to acquire vibration signals that match the current vibration scenario.

[0075] The masking signal generation module 4200 is used to generate a masking signal that matches the vibration signal, the masking signal being used to mask the vibration noise generated by the motor under the drive of the vibration signal.

[0076] The motor drive module 4300 is used to drive the motor to vibrate according to the vibration signal and the masking signal; wherein the vibration signal and the masking signal have the same duration.

[0077] In some embodiments, the masking signal generation module 4200 is used for: Obtain the target frequency band and target amplitude; The masking signal is generated based on the target frequency band and the target amplitude.

[0078] In some embodiments, obtaining the target frequency band includes: Obtain the first correspondence between vibration scenarios and frequency bands; The frequency band corresponding to the current vibration scenario is determined based on the first correspondence and is used as the target frequency band.

[0079] In some embodiments, obtaining the target amplitude includes: Obtain the second correspondence between vibration scenarios and amplitudes; The amplitude corresponding to the current vibration scenario is determined based on the second correspondence, and is used as the target amplitude.

[0081] In some embodiments, adjusting the target amplitude based on the noise signal includes: Determine the target adjustment ratio corresponding to the amplitude of the noise signal; The target magnitude is adjusted according to the target adjustment ratio.
