[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The embodiments of this application can be applied to electronic devices. This application does not limit the product form of the electronic device, which may include but is not limited to tablet computers, wearable devices, personal computers (PCs), netbooks, etc., and can be selected according to application requirements.

[0038] Figure 1 This is a flowchart illustrating a control method disclosed in an embodiment of this application. See also... Figure 1 As shown, the control method may include:

[0039] Step 101: Obtain the first operating parameters of the first device, wherein the first device is at least one power-consuming device inside the electronic device.

[0040] The first device may be, for example, a CPU, memory, hard drive, cooling fan, or other components of an electronic device. These components are equipped with ceramic capacitors. Therefore, when the first device is in a specific working state, such as in a specific operating frequency range, the ceramic capacitor will exhibit a voltage change effect, which will cause a whistling sound and affect the user experience.

[0041] If the operating voltage of the first device changes too quickly, it will cause a rapid change in the operating frequency of the first device, which may cause its operating frequency to be in a range that is also prone to howling. Therefore, in this embodiment, the first operating parameter can be a parameter that can characterize or reflect the voltage change rate of the first device.

[0042] It should be noted that obtaining the first operating parameters of the first device can be done by simultaneously and independently acquiring the first operating parameters of multiple first devices in the electronic device. That is, the electronic device can independently detect all the first devices that may cause the howling sound, and can also independently control different first devices in the subsequent process. The parameter acquisition and control adjustment processes of different first devices do not interfere with each other, which can ensure the accuracy of the corresponding monitoring and control processes.

[0043] Step 102: If the first operating parameter satisfies the first condition, determine the operating status of the electronic device.

[0044] In this embodiment, the first operating parameter can be, but is not limited to, characterizing the voltage change rate or power change range. As previously mentioned, rapid changes in the operating frequency of the first device can cause whistling; therefore, when the voltage change rate is large, the operating frequency of the first device will inevitably change significantly. Conversely, when the power change range is large, the voltage required by the first device will also change drastically, thus causing a rapid change in the operating frequency of the first device. Therefore, in this embodiment, the first operating parameter can be any parameter that can cause a rapid change in the operating frequency of the first device, and this application is not fixed in this regard.

[0045] The first condition is to satisfy the condition that the first device generates a whistling sound. Based on the above, if the first operating parameter satisfies the first condition, the step of determining the operating state of the electronic device may include: if the voltage change rate exceeds a first set value, determining that the first condition is satisfied and obtaining the operating state of the electronic device; or, if the power change range exceeds a second set value, determining that the first condition is satisfied and obtaining the operating state of the electronic device.

[0046] Step 103: If the operating state indicates that the electronic device is in a first state, control and adjust the parameters of the first device so that the first device operates based on the second operating parameters, and the second operating parameters no longer satisfy the first condition, wherein the second operating parameters are different from the first operating parameters.

[0047] In this embodiment, the operating state of the electronic device is used to assist in determining whether to implement appropriate control to suppress the feedback when the electronic device may emit a feedback sound. It should be noted that the operating state of the electronic device is not logically related to the generation of feedback, but it helps determine whether the feedback will cause significant interference to the user. If the electronic device itself currently has audio output or generates other sounds, the feedback will not have a significant impact on the user; however, if the internal and external environment of the electronic device is relatively quiet, the feedback will interfere with the user and affect the user experience.

[0048] When an electronic device is in the first state, it indicates that the internal and external environment of the device is relatively quiet. If a howling sound were to occur, it would significantly affect the user. Therefore, in this case, the electronic device needs to be controlled to prevent howling. Specifically, this is achieved by adjusting the parameters of the first device so that it operates based on the second operating parameters. Since the second operating parameters do not meet the first condition, the first device will not produce howling when operating based on the second operating parameters. Conversely, if the electronic device is not in the first state, it means that there is already some noise in the internal and external environment of the device. Howling from the electronic device would not significantly interfere with the user, so howling can be allowed without intervention.

[0049] In this embodiment, the control method determines that the electronic device may experience a whistling sound based on the first operating parameters of the first device. It then determines the operating state of the electronic device and, based on the operating state, whether it is necessary to adjust the relevant parameters of the first device so that the user will not notice the whistling sound of the electronic device, thereby improving the user experience.

[0050] In the above embodiments, determining the operating state of the electronic device may include: acquiring the operating power consumption of the electronic device and / or the scenario of the electronic device; and determining the operating state of the electronic device based on the operating power consumption of the electronic device and / or the scenario of the electronic device.

[0051] The power consumption of an electronic device can be obtained based on power consumption statistics of each individual component, or it can be determined based on analysis of the power supply parameters of the power supply unit. The scenario of the electronic device can include application scenarios and ambient sound, where the application scenario represents which applications the electronic device is currently running, and the ambient sound represents the sound conditions of the environment in which the electronic device is currently located.

[0052] In one implementation, the operating state of an electronic device can be determined solely based on its power consumption. If the device's power consumption exceeds a set value, it is in a high-power state. Its cooling modules, such as cooling fans, may operate at high speed, generating noise. Even if the device emits a whistling sound, the noise from the cooling module overlaps, making it indistinguishable to the user. Therefore, when the device is not in its first state, no action is taken, and the whistling sound is allowed. However, if the device's power consumption is below the set value, it can be considered in its first state—a relatively quiet state. In this case, a whistling sound would be very noticeable and abrupt, negatively impacting the user experience.

[0053] In another implementation, the operating state of an electronic device can be determined solely based on the device's context. For example, in scenarios such as gaming, screen mirroring, online meetings, or video conferencing, where the device itself has audio output, it can be considered not in its primary state. Alternatively, if the ambient noise level exceeds the set volume, it can also be considered not in its primary state, and the feedback noise will be at least partially masked by other sounds, not causing significant independent interference to the user. Therefore, feedback noise is permissible in these situations. However, if the electronic device is in an office setting or in a very quiet environment, it can be considered in its primary state, requiring control to prevent feedback noise to avoid disturbing the user.

[0054] Of course, the operating state of an electronic device can also be determined based on both its power consumption and the scenario in which it is used. For example, if it is determined that the power consumption of the electronic device is lower than a set power consumption value, and the scenario of the electronic device conforms to a preset scenario, then it can be determined that the electronic device does not meet the first state. The scenario of the electronic device conforming to the preset scenario may include, but is not limited to, at least one of the following: the application scenario of the electronic device conforms to a preset application scenario, and / or the sound environment in which the electronic device is located conforms to a preset environmental scenario.

[0055] In one example, the electronic device's operating power consumption is lower than the set power consumption value, indicating that the electronic device is in a light-load state and will not emit any noise. The electronic device's scenario matches the preset scenario, which could be that the electronic device is running an application with audio content, or that the ambient sound volume is very high. In this case, the user can already hear some sounds (from the electronic device or the environment), so the howling sound will not significantly affect the user. Therefore, it can be considered that the electronic device is not in the first state, and the electronic device is allowed to generate howling.

[0056] In another example, if the power consumption of the electronic device is higher than the set power consumption value, the electronic device itself will generate some noise from the heat dissipation module, regardless of whether the scenario of the electronic device meets the preset scenario. At this time, the user can also hear some noise, so the howling sound will not significantly affect the user. It can be considered that the electronic device is not in the first state, and the electronic device is allowed to generate howling.

[0057] In another implementation, if the operating power consumption of the electronic device is lower than a set power consumption value, the application scenario of the electronic device does not meet a preset scenario, and the sound environment in which the electronic device is located meets a preset scenario, then it can be determined that the electronic device does not meet the first state. The determination that the sound environment in which the electronic device is located meets a preset scenario can include: acquiring an ambient sound value, and when the ambient sound exceeds a set value, determining that the environment in which the electronic device is located meets a preset scenario.

[0058] In a corresponding example, the electronic device operates at a power consumption lower than the set power consumption value, is in a light load state, and does not emit any noise. The electronic device is not running any applications with audio output content, but the environment around the electronic device is very noisy. Therefore, the howling sound will not significantly affect the user. It can be considered that the electronic device is not in the first state, and the electronic device is allowed to produce howling.

[0059] Furthermore, if the operating power consumption of the electronic device is lower than the set power consumption value, the application scenario of the electronic device does not meet the preset scenario, and the sound environment in which the electronic device is located does not meet the preset scenario, then it can be determined that the electronic device meets the first state. In this case, there is no obvious sound inside or outside the electronic device. If the electronic device produces a howling sound, it will significantly affect the user. Therefore, it is necessary to control and adjust the parameters of the first device so that the first device operates based on the second operating parameters that do not meet the first condition, thereby preventing howling.

[0060] Figure 2 This is a schematic diagram of the control method implementation architecture disclosed in an embodiment of this application. The AI ​​chip is the main execution body of the control method, capable of detecting the voltage change rate and obtaining system power consumption through the processing chip PAC1934. Figure 2 (The power consumption sources are only shown as CPU power supply and GPU power supply as examples.) Then, based on the BIOS (Basic Input Output System), a scheme to suppress the whistling is implemented, including reducing the voltage change rate, turning off power saving and overclocking functions, and setting the operating frequency.

[0061] Figure 3 This is a flowchart illustrating an example implementation of a control method disclosed in an embodiment of this application. (In conjunction with...) Figure 3 As shown, the implementation process of the control method may include:

[0062] 1. When the AI ​​chip detects a voltage change, such as... Figure 4 The change indicated by the solid line suggests that capacitor whistling may occur.

[0063] 2. The AI ​​chip accurately determines the user's current usage mode by real-time detection of the system's underlying power consumption and combining parameters such as OS processes and CPU / GPU utilization. If it is a low-load, idle, or office scenario, it will determine that capacitor whistling will affect the user experience. If it is a high-power (cooling fan speed greater than a certain value) or audio-visual entertainment mode, it will not affect the user experience.

[0064] 3. If it is determined that the issue affects users, parameters such as slew rate (voltage change rate) will be changed to optimize capacitor whistling.

[0065] The above content details the various scenarios corresponding to different operating states of electronic devices, which helps those skilled in the art to better understand and implement the technical solutions of this application.

[0066] In the foregoing embodiments, the step of controlling and adjusting the parameters of the first device if the operating state characterizes the electronic device as being in a first state may include: adjusting the operating frequency of the first device and / or the state of the working units contained in the first device if the operating state characterizes the electronic device as being in a first state.

[0067] As described above, if the electronic device is in the first state, it is necessary to suppress the howling sound generated by the electronic device. The reason for the howling sound may be that the voltage change rate of the first device is relatively large or the power consumption change range is relatively large. Therefore, in this embodiment, the voltage change rate and power consumption change range of the first device can be indirectly limited by narrowing the operating frequency range or power consumption range of the first device.

[0068] Specifically, if the first device is a CPU, disabling the CPU's overclocking function lowers the CPU's upper limit of operating frequency, narrowing its operating frequency range. This prevents the CPU's voltage from fluctuating rapidly, thus avoiding coil whine. Alternatively, disabling the power-saving function of electronic devices prevents their power consumption from dropping to very low values, thus avoiding significant fluctuations in power consumption and indirectly preventing coil whine.

[0069] Based on the disclosure of the foregoing embodiments, the control method may further include: controlling and adjusting the parameters of the second device, including: adjusting the operating frequency and / or the voltage change rate.

[0070] The second device can be a power supply device for an electronic device. Controlling and adjusting the parameters of the second device can involve controlling and adjusting the operating frequency of the power supply device. By adjusting the operating frequency, large fluctuations in device power consumption can be avoided, keeping the overall power consumption of the electronic device within a relatively stable range, thereby effectively preventing the generation of whistling noise.

[0071] Alternatively, controlling the parameters of the second device can involve controlling the rate of voltage change of the power supply device. By reducing the rate of voltage change, the speed at which the power supply voltage of the electronic device changes slows down, thereby reducing the probability of a whistling sound. Figure 4 The embodiments of this application disclose a comparison example diagram before and after voltage change slope adjustment, wherein the solid line represents a larger voltage change rate and the dashed line represents a smaller voltage change rate.

[0072] In other implementations, after controlling and adjusting the parameters of the first device, the control method may further include: after a set time, releasing the control right to adjust the parameters of the first device, so that the first device can operate adaptively based on system requirements.

[0073] In this implementation, after adjusting the parameters of the first device to prevent whistling for a period of time, the system's operational requirements may no longer cause excessive voltage change rates or significant power range fluctuations. Therefore, to better serve users, control over the parameter adjustment of the first device can be released, allowing it to adapt to system requirements and operate without being limited by whistling-related constraints. For example, a CPU, after its overclocking function was previously disabled, can have it restored after a period of time to provide users with comprehensive and rich functionality and a better user experience.
