Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a tuning method, device, electronic equipment and computer-readable storage medium. Background Art

[0002] Smart PA (smart audio power amplifier) ​​is commonly used in smart phones, tablets, smart doorbells and other fields. Specifically, the chip has a built-in smart PA. The typical PA output power is usually 5.7W, and the PA drive can reach 10W after Boost. In order to prevent the speaker from being damaged by being under high driving power for a long time, the maximum output of the PA is usually limited. Currently, the maximum PA power of most speakers is usually 12W. When the audio file being played contains an audio signal greater than 12W, the audio file cannot be played according to the required power due to the limitation of the PA maximum power, and the optimal sound quality and loudness cannot be achieved, which affects the sound effect of the device.

[0003] In view of this, how to provide a tuning method, device, electronic device and computer-readable storage medium that solve the above technical problems has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0014] Optionally, the predicting the power supply parameters of the speaker at the next moment based on the power supply parameters at previous moments and the power supply parameters at the current moment includes:

[0015] Using a linear regression fitting algorithm to determine whether the fitting curves corresponding to the power supply parameters at the current moment and the power supply parameters at the previous moments converge, and if so, performing linear regression fitting on the power supply parameters at the current moment and the power supply parameters at the previous moments to obtain a new fitting curve;

[0016] The power supply parameters of the speaker at the next moment are obtained based on the new fitting curve.

[0017] Optionally, before using a linear regression fitting algorithm to determine whether the fitting curves corresponding to the power supply parameters at the current moment and the power supply parameters at the previous moments converge, the method further includes:

[0018] Calculating the residual between the power supply parameter at the current moment and the power supply parameter at the previous moment;

[0019] If the residual does not exceed the preset residual threshold, proceed to the next step.

[0020] Optionally, also include:

[0021] When the fitting curves corresponding to the power supply parameters at the current moment and the power supply parameters at the previous moments do not converge, or when the residual exceeds the preset residual threshold, the power supply parameters of the speaker at the next moment are obtained based on the fitting curves corresponding to the power supply parameters at the previous moments.

[0022] Optionally, the power supply parameters include current and voltage.

[0023] Optionally, also include:

[0024] When the temperature value reaches a second temperature threshold, the control device is restarted; the second temperature threshold is greater than the first temperature threshold.

[0025] The present invention also provides a tuning device, which is applied to an electronic device provided with a speaker, comprising:

[0026] The acquisition module is used to obtain the power supply parameters of the speaker at the current moment;

The method is applied to an electronic device equipped with a speaker, including: obtaining the power supply parameters of the speaker at the current moment; when the total number of previous moments is greater than a preset number, predicting the power supply parameters of the speaker at the next moment based on the power supply parameters of the previous moments and the power supply parameters of the current moment; determining the target output power of the audio power amplifier based on the power supply parameters at the next moment; when the target output power is greater than the output threshold of the audio power amplifier, judging that the speaker temperature has not reached the first temperature threshold; if so, canceling the output threshold setting of the audio power amplifier.

[0036] It can be seen that during the operation of the electronic device, the embodiment of the present invention obtains the power supply parameters of the speaker at the current moment. When the total number of previous moments is greater than the preset number, the power supply parameters of the speaker at the next moment are predicted based on the power supply parameters at the current moment and the power supply parameters of previous moments. The target output power of the audio power amplifier PA is obtained based on the power supply parameters at the next moment, and then the target output power is compared with the output threshold of the PA. When the target output power is greater than the output threshold of the PA, the temperature of the speaker is further obtained. When the temperature of the speaker does not reach the first temperature threshold, the output threshold setting of the PA is canceled. Therefore, when the audio signal at the next moment is played, the PA can output the output power actually required to drive the speaker to meet the audio signal at the next moment, thereby improving the overall maximum output power and loudness of the whole machine, and improving the speaker performance, sound quality and sound effect.

[0040] The embodiments of the present invention provide a tuning method, device, electronic device, and computer-readable storage medium, which improve the overall maximum output power and loudness of the entire device during use, and enhance the performance, sound quality, and sound effects of the speaker.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0042] Please refer to Figure 1 , Figure 1 A flow chart of a tuning method provided in an embodiment of the present invention. The tuning method is applied to an electronic device equipped with a speaker, and includes:

[0043] S110: Obtain the power supply parameters of the speaker at the current moment;

[0044] It should be noted that, in the embodiment of the present invention, during the process of driving the speaker, the power supply parameters of the speaker at the current moment are obtained, which may specifically include the current and voltage of the speaker at the current moment.

[0045] S120: When the total number of previous moments is greater than a preset number, predicting the power supply parameters of the speaker at the next moment based on the power supply parameters of the previous moments and the power supply parameters of the current moment;

[0046] Specifically, after the device is started, the speaker is driven according to each audio signal of the audio file to be played. During the operation of the speaker, the power supply parameters are obtained at each moment starting from the start of the audio file playback. For the current moment, if the total number of previous moments is greater than a preset value, it means that there are sufficient data points to predict the power supply parameters of the speaker at the next moment. Specifically, the power supply parameters of the next moment can be predicted based on the power supply parameters of the previous moments and the power supply parameters of the current moment. If the total number of previous moments does not reach the preset number, the power supply parameters of the speaker at the next moment are not predicted. At the next moment, power output continues in the existing manner of the audio power amplifier PA. Until the total number of previous moments reaches the preset number, the power supply parameters of the next moment are predicted.

[0047] S130: Determine a target output power of the audio power amplifier based on the power supply parameters at the next moment;

[0048] Specifically, after determining the power supply parameters at the next moment, the target output power of the audio power amplifier PA is further determined based on the power supply parameters, thereby predicting the power required for the audio signal to be played at the next moment. That is, if the speaker has the power supply parameters at the next moment, what should be the output power of the PA? The output power of the PA is thus determined to further determine whether the output power is greater than the output threshold of the PA.

[0049] S140: When the target output power is greater than the output threshold of the audio power amplifier, it is determined that the speaker temperature has not reached the first temperature threshold. If it has reached the first temperature threshold, the process proceeds to S150;

[0050] S150: Cancel the output threshold setting of the audio power amplifier.

[0051] Specifically, after determining the target output power of the PA at the next moment, the target output power is compared with the output threshold of the PA. When the target output power is greater than the output threshold, it means that the power required for the audio signal to be played at the next moment is greater than the output threshold of the PA. In order to make the sound signal played by the speaker meet the actual needs of the audio signal and ensure that the speaker is not damaged, the output threshold setting of the PA can be canceled if the speaker temperature does not reach the first temperature threshold. That is, when it is predicted that the target output power of the PA required at the next moment is greater than the output threshold and the speaker temperature does not reach the first temperature threshold, the output threshold setting of the PA is canceled. Therefore, when the next moment arrives, the actual power required for the audio signal can be determined based on the corresponding audio signal, and the PA can output the power to drive the speaker, so that the sound played by the speaker is more in line with actual needs and the sound quality is improved.

[0052] Specifically, in practical applications, a temperature sensor can be placed near the speaker to monitor the speaker's temperature. For example, in practical applications, for audio signals with large dynamic ranges, such as drum sounds and gunshots, with dynamic ranges exceeding 80dB, the above-mentioned method provided in the embodiments of the present invention can control the PA's signal compression ratio in real time, adjust the PA signal, and maximize the use of the speaker's stroke range, thereby achieving better bass effect and loudness.

[0053] Furthermore, before canceling the output threshold setting of the audio power amplifier, the method may further include:

[0054] It is determined whether the output threshold setting of the audio power amplifier has been canceled. If not, the step of canceling the output threshold setting of the audio power amplifier is performed.

[0055] It should be noted that in actual application, when it is determined that the output threshold setting of the PA can be canceled, it can be further determined whether the output threshold setting of the PA has been canceled. If it has been canceled, the operation is terminated; if it has not been canceled, the step of setting the output threshold of the audio power amplifier is executed.

[0056] Additionally, the method may further include:

[0057] When the speaker temperature reaches the first temperature threshold, it is determined whether the audio power amplifier has canceled the output threshold setting. If so, the output threshold setting of the audio power amplifier is restored. If not, the process ends.

[0058] It should also be noted that when it is detected that the speaker temperature reaches the first temperature value, it is further determined whether the PA has canceled the output threshold setting. If canceled, the PA output threshold setting is restored to further ensure that the speaker will not be damaged due to excessive temperature.

[0059] Furthermore, the process of predicting the power supply parameters of the speaker at the next moment based on the power supply parameters at previous moments and the power supply parameters at the current moment in S120 may specifically include:

[0060] A linear regression fitting algorithm is used to determine whether the fitting curves corresponding to the current power supply parameters and the power supply parameters at previous moments converge. If converged, a linear regression fitting is performed on the current power supply parameters and the power supply parameters at previous moments to obtain a new fitting curve;

[0061] The power supply parameters of the speaker at the next moment are obtained based on the new fitting curve.

[0062] It should be noted that it is possible to specifically determine whether the power supply parameters at the current moment converge with the fitting curves corresponding to the power supply parameters at the previous moments. If converged, a linear regression fitting can be performed based on the power supply parameters at the current moment and the power supply parameters at the previous moments to obtain a new fitting curve, and the power supply parameters at the next moment are obtained based on the new fitting curve, that is, the power supply parameters of the speaker at the next moment are predicted.

[0063] Furthermore, before using the linear regression fitting algorithm to determine whether the fitting curves corresponding to the power supply parameters at the current moment and the power supply parameters at the previous moments converge, the method may further include:

[0064] Calculate the residual between the power supply parameters at the current moment and the power supply parameters at the previous moment;

[0065] Proceed to the next step if the residual does not exceed the preset residual threshold.

[0066] Specifically, before determining whether convergence has occurred, it is also possible to first determine whether the point corresponding to the power supply parameter at the current moment is an abnormal point. If it is an abnormal point, the power supply parameter at the next moment is obtained and prediction is continued. If it is not an abnormal point, the subsequent step of using a linear regression fitting algorithm to determine whether the fitting curve corresponding to the power supply parameter at the current moment and the power supply parameter at each previous moment has converged is performed. Specifically, the residual between the power supply parameter at the current moment and the power supply parameter at the previous moment can be calculated. If the residual is greater than a preset residual threshold, it means that the point corresponding to the power supply parameter at the current moment is an abnormal point. Otherwise, it is a normal point. In the case where the residual exceeds the preset residual threshold, the power supply parameter at the next moment is used as the power supply parameter at the current moment, and the process returns to the step of obtaining the power supply parameter of the speaker at the current moment.

[0067] Furthermore, the method may further include:

[0068] When the fitting curves corresponding to the power supply parameters at the current moment and the power supply parameters at the previous moments do not converge, or when the residual exceeds the preset residual threshold, the power supply parameters of the speaker at the next moment are obtained based on the fitting curves corresponding to the power supply parameters at the previous moments.

[0069] It is understood that the above-described adjustments in the embodiments of the present invention can make the PA output power greater than its output threshold, thereby better meeting the actual requirements of the audio file. However, for audio signals with low dynamic range but high high-frequency components, the speaker voice coil will heat up rapidly, and the speaker may suffer irreversible damage due to overheating. Therefore, in order to further protect the speaker operating at high power or large stroke for a long time, the method may also include:

[0070] When the temperature value of the speaker is greater than a second temperature threshold, the control device is restarted, and the second temperature threshold is greater than the first temperature threshold.

[0071] That is to say, in the embodiment of the present invention, a temperature sensor can be set near the speaker, and the temperature of the speaker can be monitored by obtaining the temperature sensor. The temperature value of the temperature sensor is compared with a second temperature threshold. When the temperature value of the temperature sensor is greater than the second temperature threshold (for example, 70°C), it means that the temperature of the speaker is too high. At this time, the MCU (Microcontroller Unit) can be used to control the device to restart to prevent the speaker from being damaged due to overheating.

[0072] Furthermore, in order to facilitate subsequent maintenance of the speaker, the method may further include:

[0073] Based on the power supply parameters at the current moment, determine the working power of the speaker at the current moment;

[0074] Record the current working power.

[0075] It can be seen that, during the operation of the electronic device, the embodiment of the present invention obtains the power supply parameters of the speaker at the current moment. When the total number of previous moments is greater than the preset number, the power supply parameters of the speaker at the next moment are predicted based on the power supply parameters at the current moment and the power supply parameters of previous moments. The target output power of the audio power amplifier PA is obtained based on the power supply parameters at the next moment, and then the target output power is compared with the output threshold of the PA. When the target output power is greater than the output threshold of the PA, the temperature of the speaker is further obtained. When the temperature of the speaker does not reach the first temperature threshold, the output threshold setting of the PA is canceled, so that when the audio signal at the next moment is played, the PA can output the output power actually required to meet the audio signal at the next moment to drive the speaker, thereby improving the overall maximum output power and loudness of the whole machine, and improving the speaker performance, sound quality and sound effect.

[0076] Based on the above embodiment, an embodiment of the present invention further provides a tuning device, which is applied to an electronic device provided with a speaker, and includes:
