and secondly, inputting the temperature into an offset network model to obtain the target frequency offset output by the offset network model.
In the first mode, the terminal device is provided with a frequency offset list. The frequency offset list includes a corresponding relationship between a set temperature range and a set frequency offset, where in different corresponding relationships, the temperature ranges are different, and the frequency offsets corresponding to different temperature ranges are different. And the terminal equipment acquires the temperature range included by the corresponding relation, determines the temperature range to which the acquired temperature belongs, namely a target temperature range, and takes the frequency offset corresponding to the target temperature range in the frequency offset list as the target temperature offset corresponding to the acquired temperature.
In one example, the frequency offset list is shown in table 1, and the temperature ranges included in the set correspondence relationship include: -20 to 25 ℃, 25 to 30 ℃ and 30 to 80 ℃, and when the temperature of the collected terminal device is-10 ℃, of-20 to 25 ℃, 25 to 30 ℃ and 30 to 80 ℃, the target temperature range to which-10 ℃ belongs is-20 to 25 ℃, the corresponding target frequency offset is-2 Hertz (HZ); and when the acquired temperature of the terminal equipment is 20 ℃, and the target temperature range is 25-30 ℃, the corresponding target frequency offset is 0 HZ.

| 30-80 | +5 |
Wherein in table 1, the frequency offset is-2, indicating that the sampling frequency of the resonator device is decreased by 2HZ, and +5 indicating that the sampling frequency of the resonator device is increased by 5 HZ.
In the embodiment of the invention, the frequency offset has three types of positive numbers, zero numbers and negative numbers. When the frequency offset is positive, the sampling frequency of the resonance device is increased in a representation mode; when the frequency offset is zero, the sampling frequency of the characterization resonance device is unchanged; the characterization reduces the sampling frequency of the resonant device when the frequency offset is negative.

After the terminal equipment determines the target frequency offset, the sampling frequency of a driving signal for driving the resonance device to vibrate is adjusted through the target frequency offset so as to adjust the sampling frequency of the resonance device, the sampling frequency is consistent with the natural frequency of the resonance device, and the vibration of the resonance device in the terminal equipment is controlled to be corrected.
Alternatively, as shown in fig. 2, S103 includes:
and S1031, acquiring a reference frequency of a driving signal for driving the resonance device to vibrate.
Here, the reference frequency is a sampling frequency of a drive signal that drives the resonance device to vibrate set by the terminal device. Optionally, the reference frequency of the driving signal is the same in different scenarios.

F＝F ref+ Δ F formula (1).
In one example, the vibration time of the resonance device is t1 to t2, wherein the waveform of the drive signal before the correction based on the target frequency is as shown in fig. 3, the sampling frequency during the period from t1 to t2 is the reference frequency, and the magnitude of the reference frequency is f1, and when the temperature of the electronic device is 40 ℃, the waveform of the drive signal after the correction based on the target frequency is as shown in fig. 4, the sampling frequency during the period from t1 to t2 is the target frequency, and the magnitude of the target frequency is f2, wherein f1< f 2.
S1033, driving the resonance device to vibrate at the target frequency.
The terminal equipment drives the resonance device to vibrate by using the driving signal with the sampling frequency as the target frequency, so that the sampling frequency is adaptive to the natural frequency of the resonance device, and the vibration of the terminal equipment is corrected.
In the embodiment of the invention, when the sampling frequency of the driving signal is adjusted, the waveform of the driving signal is not adjusted, so that after the vibration of the resonance device in the terminal equipment is controlled based on the target frequency offset, the resonance device can continuously perform different vibrations in different scenes, thereby meeting the requirements of multiple scenes and enabling a user to distinguish different scenes according to the current vibration condition.
In the embodiment of the present invention, after S103, as shown in fig. 5, the method further includes:
and S104, detecting the vibration frequency of the resonance device.
Here, the frequency of the vibration when the resonance device is driven at the obtained sampling frequency corrected for the sampling frequency of the drive signal based on the target frequency offset amount is detected, thereby monitoring the correction effect of the current target frequency offset amount.
Alternatively, when the temperature of the terminal device belongs to the temperature range corresponding to the current target frequency offset, the frequency of the vibration of the resonance device is detected.
And S105, correcting the target frequency offset according to the detected frequency to obtain the corrected target frequency offset.
And the terminal equipment corrects the target frequency offset according to the correction effect of the detected current target frequency offset. Alternatively, when the correction effect reaches the expected correction effect, the current target frequency offset is not corrected. Optionally, when the correction effect does not reach the expected correction effect, the current target frequency offset is corrected.
And when the terminal equipment corrects the target frequency offset to obtain the corrected target frequency offset, controlling the vibration of the resonance device by using the corrected target frequency offset.
Optionally, a reference frequency of a drive signal driving the resonant device to vibrate is used as a measure of the effectiveness of the correction. At this time, S105 includes: comparing the detected frequency with a reference frequency of a drive signal driving the resonating means to vibrate; and when the frequency difference value between the detected frequency and the reference frequency is greater than a specified frequency difference threshold value, correcting the target frequency offset through the frequency difference value to obtain the corrected target frequency offset.
When the frequency difference between the detected frequency and the reference frequency is greater than a specified frequency difference threshold, the characteristic correction effect does not reach the expected correction effect, and the target frequency offset needs to be corrected. And when the frequency difference value between the detected frequency and the reference frequency is not greater than a specified frequency difference threshold value, representing that the correction effect reaches the expected correction effect without correcting the target frequency offset.
The method for correcting the target frequency offset includes: and correcting the target frequency offset through the frequency difference value of the detected frequency and the reference frequency to obtain the corrected target frequency offset. Here, the corrected target frequency shift amount Δ FSchoolCan be calculated by equation (2):
ΔF school＝F Difference (D)+ Δ F equation (2);
wherein, FDifference (D)Is the difference in frequency between the detected frequency and the reference frequency.
In the embodiment of the invention, the target frequency offset or the offset network model is updated after the corrected target frequency offset is obtained.
Optionally, when the manner in which the terminal device determines the target frequency offset corresponding to the temperature is the first manner, the target frequency offset in the correspondence between the temperature range and the frequency offset is updated based on the corrected target frequency offset.
Here, the target frequency offset in the frequency offset list is updated to the corrected target frequency offset.
In an example, the correspondence relationship of the frequency offset list is shown in table 1, when the temperature is 40 ℃, the target frequency offset is 5HZ, and the corrected target frequency offset obtained by correcting the target frequency offset is 6HZ, and then the updated frequency offset list is shown in table 2.

| Temperature range, unit: degree centigrade | Frequency offset, unit: HZ |
| -20-25 | -2 |
| 25-30 | 0 |
| 30-80 | +6 |
Optionally, when the mode of determining the target frequency offset corresponding to the temperature by the terminal device is the mode two, the parameter of the offset network model is updated based on the corrected target frequency offset.
And the terminal equipment updates the parameters of the offset network model based on the current temperature and the corrected target frequency offset, so that the offset network model is output, the frequency offset output by the offset network model aiming at the input temperature adapts to the service condition of the terminal equipment, and the sampling frequency of the driving signal is kept to be adapted to the natural frequency of the resonance device.
In the embodiment of the invention, the target frequency offset or the parameters of the offset network model in the corresponding relation are updated through the corrected target frequency offset, so that the corresponding relation between the temperature range for determining the target frequency offset and the frequency offset or the offset network model is subjected to feedback regulation through a correction effect to accurately determine the frequency offset for eliminating the vibration deviation of the resonance device caused by the temperature, and a frequency offset list stored in the terminal equipment and the offset network model can be dynamically adjusted along with the adjustment of the deviation of the natural frequency of the resonance device in the terminal equipment.
