[0050] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The exemplary embodiments described below are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0051] The present disclosure provides a vibration intensity control method, which can be applied to electronic devices equipped with motors, such as smart phones, tablet computers, and smart headphones. Figure 1 1 is a flow chart showing a vibration intensity control method according to an exemplary embodiment, including steps 11 to 13:

[0052] In step 11, audio feature data of the currently playing audio is obtained.

[0053] In this embodiment, the processor in the electronic device can obtain audio feature data of the currently playing audio, and the audio feature data may include audio frequency and audio amplitude. The acquisition method may include:

[0054] In the first approach, the audio is played by an electronic device, which may include an encoder for decoding and encoding the audio. The processor can send the audio data to the encoder, which processes the audio data, such as converting the audio protocol, and then outputs the corresponding audio data.

[0055] The processor can sample the audio signal from the output end of the encoder according to a preset detection cycle and obtain the audio data characteristics of the audio signal in the current detection cycle. For example, the processor can perform Fourier transform on the audio signal to obtain the frequency of the audio signal. Taking into account that the audio signal in each detection cycle may be composed of audio signals of multiple frequencies, in this scenario, the processor can use the audio frequency corresponding to the dominant audio signal as the audio frequency of the current detection cycle, where dominance means that the energy of the audio signal of a certain frequency accounts for a proportion of the energy of the audio signal of the current detection cycle that exceeds a preset proportion (such as 50%).

[0056] Method 2: The currently playing audio is played by an audio device outside the electronic device. In this case, the electronic device may include an audio acquisition device, such as a microphone, for acquiring the collected audio signal. The audio acquisition device can sample the audio signal according to a preset detection period. Then, the processor performs Fourier transform on the audio signal to obtain the frequency of the audio signal. Taking into account that the audio signal in each detection period may be composed of audio signals of multiple frequencies, in this scenario, the processor can use the audio frequency corresponding to the dominant audio signal as the audio frequency of the current detection period, where dominance means that the energy of the audio signal of a certain frequency accounts for a proportion of the energy of the audio signal of the current detection period that exceeds a preset proportion (such as 50%).

[0057] In step 12, a target control waveform of the motor in the current detection cycle is obtained according to the audio feature data and a preset correspondence between the audio feature data and the vibration intensity.

[0058] In this embodiment, the electronic device may store a preset correspondence between audio feature data and vibration intensity. This correspondence includes multiple control waveforms, each corresponding to a vibration intensity. Thus, the processor can query this correspondence based on the audio feature data to obtain the control waveform corresponding to the audio feature data, thereby obtaining the target control waveform. In other words, it can obtain the vibration intensity of the motor corresponding to the audio feature data.

[0059] In this embodiment, the corresponding relationship between the above audio feature data and vibration intensity can be obtained in the following way, see Figure 2 ,include:

[0060] In step 21, the processor may obtain an audio sample and process the audio sample in a manner similar to step 11 to obtain an audio frequency range of the audio sample. The audio frequency range refers to a frequency range formed by the minimum and maximum frequencies of the audio sample, for example, 20 Hz to 20 kHz.

[0061] At the same time, the processor can obtain the operating frequency range of the motor. The operating frequency range refers to the frequency range formed by the maximum and minimum frequencies that the vibrator in the motor can reach when working, such as 100Hz to 300Hz. In actual applications, each operating frequency corresponds to a control waveform, and each control waveform can include a certain number of sine waves, the effect is as follows Figure 3 As shown, the number of sine waves is positively correlated with the vibration frequency of the motor.

[0062] In step 22, the processor may establish a correspondence between the audio frequency range and the operating frequency range, and obtain a first control waveform corresponding to the operating frequency of each audio frequency.

[0063] In one example, the correspondence between the audio frequency and the operating frequency can be a frequency-to-frequency correspondence, that is, each audio frequency within the audio frequency range and each operating frequency within the operating frequency range are in a one-to-one correspondence, and the effect is as follows: Figure 4 In this way, in this embodiment, the vibration frequency of the motor follows the precise change of the audio frequency, thereby achieving precise control of the motor operating frequency.

[0064] In another example, considering that the change in vibration intensity caused by adjusting the control waveform within a certain frequency range will not be perceived by the user, for example, when the motor operates at 100Hz and 110Hz, the user cannot feel the change in vibration intensity. Therefore, the processor can establish a one-to-one correspondence between each sub-band in the audio frequency range and each sub-band in the operating frequency range, and the effect is as follows: Figure 5 As shown. For example, if the audio frequency range is divided into 10 sub-bands and the operating frequency range is divided into 10 sub-bands, the first sub-band in the audio frequency range (20-2kHz) corresponds to the first sub-band in the operating frequency range (20-40Hz). In this way, in this embodiment, the motor's vibration frequency can substantially follow the audio frequency, and the user can perceive that the vibration intensity changes continuously with the audio frequency, which can reduce the number of first control waveforms.

[0065] In step 23, the processor may obtain the audio volume range of the audio sample, wherein the audio volume range refers to the audio range formed by the minimum amplitude and the maximum amplitude of the audio signal in the audio sample, and the larger the volume, the larger the amplitude of the corresponding audio signal.

[0066] At the same time, the processor can obtain the voltage amplitude range of the motor. The voltage amplitude range refers to the voltage range formed by the maximum voltage amplitudes of multiple control waveforms corresponding to the motor, and each control waveform corresponds to a maximum vibration amplitude. In other words, each control waveform corresponds to a maximum control voltage, that is, a maximum voltage amplitude, and multiple control waveforms correspond to multiple maximum voltage amplitudes respectively. The maximum and minimum values ​​obtained after sorting these maximum voltage amplitudes form the voltage amplitude range, such as Figure 6 The maximum voltage amplitudes of waveforms C1, C2, and C3 shown in FIG are V1, V2, and V3, respectively.

[0067] In step 24 , the processor may establish a one-to-one correspondence between each audio volume within the audio volume range and each maximum voltage amplitude within the voltage amplitude range, thereby obtaining a correspondence between the audio volume and the maximum voltage amplitude.

[0068] In one example, the correspondence between audio volume and maximum voltage amplitude can be one volume value for each maximum voltage amplitude, i.e., there is a one-to-one correspondence between each audio volume within the audio volume range and each maximum voltage amplitude within the voltage amplitude range. In this way, in this embodiment, the motor vibration amplitude precisely follows the audio volume, achieving precise control of the motor vibration amplitude.

[0069] In another example, considering that changes in the motor's vibration amplitude within a certain range are not perceptible to the user, for example, when the motor is operating at 2.5V and 2.6V, the user cannot sense the change in vibration amplitude. Therefore, the processor can establish a one-to-one correspondence between each sub-volume segment within the audio volume range and each sub-amplitude segment within the voltage amplitude range. In this way, in this embodiment, the motor's vibration amplitude can substantially track changes in the audio volume, and the user can perceive that the vibration amplitude changes continuously with the audio volume, thereby reducing the number of first control waveforms.

[0070] In step 25, for each first control waveform, the processor can adjust the maximum voltage amplitude of the first control waveform based on the correspondence between the audio volume and the maximum voltage amplitude, thereby obtaining a second control waveform corresponding to each audio volume in the audio volume range, and all second control waveforms constitute the correspondence between the audio feature data and the vibration intensity.

[0071] In other words, step 23 only obtains the first control waveforms at different frequencies, and step 25 gives each first control waveform a different maximum voltage amplitude, thereby obtaining several second control waveforms, each of which has a different maximum voltage amplitude. The effect is as follows: Figure 6 As shown, Figure 6 Figure 1 shows three second control waveforms: waveform C1, waveform C2, and waveform C3. Waveforms C1, C2, and C3 have the same frequency, while their maximum voltage amplitudes are V1, V2, and V3, respectively. In other words, the corresponding relationship includes several second control waveforms indexed by audio volume and audio frequency.

[0072] In step 13 , the motor is driven according to the target control waveform to adjust the vibration intensity of the motor to the target vibration intensity corresponding to the target control waveform.

[0073] In this embodiment, the processor can drive the motor according to the above-mentioned target control waveform, or send the above-mentioned target control waveform to the driving circuit of the motor, and the driving circuit drives the motor according to the target control waveform, so that the vibration intensity of the motor can be adjusted to the target vibration intensity corresponding to the target control waveform, for example 2.5G, where G represents the acceleration of gravity.

[0074] At this point, the disclosed embodiment can obtain audio feature data for the currently playing audio. Then, based on the audio feature data and the preset correspondence between audio feature data and vibration intensity, the target control waveform for the motor within the current detection cycle is obtained. The motor is then driven according to the target control waveform to adjust the motor's vibration intensity to the target vibration intensity corresponding to the target control waveform. In this way, the motor's vibration intensity in this embodiment can change in accordance with the currently playing audio, allowing the user to experience different tactile feedback, which is beneficial for improving the user experience.
