Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of this application.

It is to be understood that the figures so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in orders other than those illustrated or described herein, and that "first," "second," etc. are distinguished Objects are usually of one type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

However, when users use some functions of electronic devices, the power required by the load will jump, causing voltage fluctuations in the hardware circuits. The components in the hardware circuit are affected by voltage fluctuations Loud and prone to making noise.

Specifically, the layout of hardware circuits implemented on printed circuit boards (PCBs) in electronic devices is becoming increasingly compact. In hardware circuits, components such as capacitors are often packaged. The hardware circuit in the electronic device is connected to the load. If the load is in working condition, the required power consumption is unstable and the power consumption is prone to jump, which in turn easily causes the inverse piezoelectric effect, causing the capacitors and other components packaged in the hardware circuit to vibrate and generate noise. .

To this end, embodiments of the present application provide a power circuit control method, device, electronic device, and readable storage medium. In the embodiment of the present application, the electronic device includes a power circuit, a wireless communication unit and a power supply. The power circuit includes a charge pump connected to the wireless communication unit and the power supply respectively. The charge pump is used to control the output current of the power supply. Specifically, when the wireless communication unit is in the wireless communication state, the audio playback mode of the electronic device is detected. When the audio playback mode is the earpiece mode, adjust the operating frequency of the charge pump to the first target frequency. By adjusting the output current of the power supply to the output current corresponding to the first target frequency in advance, the power consumption of the wireless communication unit can be compensated. In this way, sufficient power can be provided to the load, the voltage fluctuation range in the hardware circuit can be reduced, and components in the hardware circuit can be prevented from emitting noise due to voltage jumps.

The control method of the power circuit provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

FIG. 1 is a schematic structural diagram of a power supply circuit provided by an embodiment of the present application. As shown in Figure 1. The power supply circuit 10 includes a charge pump 11 and a wireless communication unit 12 . The power circuit can be configured in electronic equipment, and the power supply in the electronic equipment can be a built-in power supply or an external power supply. For example, the electronic device is a device with wireless communication functions, such as a mobile phone, a tablet computer, a notebook computer, or a handheld computer. As more and more functions are included in electronic devices, their performance becomes more and more complex. The charge pump 11 can be connected to the power supply in the electronic device. The charge pump 11 is used to control the output current of the power supply. As a specific example, a capacitor is used as an energy storage element in the charge pump 11 to perform voltage conversion. Specifically, by adjusting the operating frequency of the charge pump, the voltage change is controlled, thereby changing the output current. For example, by adjusting the operating frequency of the charge pump, the control voltage decreases and the current increases.

Figure 2 is a schematic flowchart of a control method for a power supply circuit provided by an embodiment of the present application. The circuit control method can be used to control the power circuit as shown in Figure 1. As shown in FIG. 1 , the method includes step 210 and step 220 .

Step 210: When the wireless communication unit is in the wireless communication state, detect the audio playback mode of the electronic device.

Specifically, the components in the hardware circuit of electronic equipment are affected by the jump in the power required by the load, and will emit noise. As an example, the load may be a wireless communication unit. The closer the distance between the user and the electronic device, the greater the impact the noise may have on the user.

Optionally, the fact that the wireless communication unit is in the wireless communication state means that the wifi function is on.

In some embodiments, before performing step 210, it may specifically include: detecting whether the wireless communication unit is in a wireless communication state.

When the wireless communication unit is in the wireless communication state, the electronic device may send data or receive data based on the wireless communication unit. Exemplarily, the wireless communication unit may include a wifi communication module. When the wireless communication unit is in the wireless communication state, the electronic device can use the wifi communication module to transmit data. The way to transmit data is to send data or receive data. Among them, when the data transmission rate of the wireless communication module is faster, the required power consumption is higher. By detecting whether the wireless communication unit is in the wireless communication state, it can be judged in time whether the operating frequency of the charge pump needs to be adjusted in advance, and noise can be avoided in advance.

Audio playback modes of the electronic device, for example, earpiece mode and non-earpiece mode, where the non-earpiece mode is such as speaker mode, silent mode, etc. It can be understood that the electronic device may include an audio playback component, and the audio data is played through the audio playback component. For example, the audio playback component may be a receiver, a single speaker, or other components capable of playing audio.

Optionally, the earpiece mode means that the earpiece of the electronic device is in use, such as answering calls through the earpiece, listening to voice information through the earpiece, etc.

Step 220: When the electronic device is in the earpiece mode, adjust the operating frequency of the charge pump to the first target frequency.

Specifically, when the audio playback mode is the earpiece mode, it can be understood that the distance between the user and the electronic device is relatively close. Scenarios where the electronic device is in handset mode, for example, the user uses the electronic device to play a spoken language Audio messages, calls made by users using electronic devices, etc. are not listed here.

The charge pump (Charger pump) operates at different frequencies, allowing the power supply to output different currents. For example, when the operating frequency of the charge pump is higher, the output current of the power supply is larger. When the charge pump operates at the first target frequency, the power supply can stably output a large current, thereby compensating the power consumption of the wireless communication unit in the wireless communication state. The first target frequency can be determined based on the preset frequency working range of the charge pump and the maximum current that the power supply can output.

In some embodiments, when the operating frequency of the charge pump is the first target frequency, the power supply can stably output a large current. Taking a dual-cell power supply in an electronic device and using a 2:1 step-down charge pump as an example, the charge pump can directly adjust the operating frequency of the charge pump to a fixed value in the normal current operating mode (Normal Current Mode, NCM). The frequency is 450kHz, so that the power supply can output large current in advance.

According to the embodiment of the present application, by adjusting the operating frequency of the charge pump to the first target frequency, the power supply can provide sufficient output current, and the transient response capability of the power supply can be improved, thereby providing sufficient power for the load and reducing the cost of the hardware circuit. Voltage fluctuation range, thereby preventing components in the hardware circuit from being affected by voltage jumps and emitting noise.

In some embodiments, after adjusting the operating frequency of the charge pump to the first target frequency, the audio playback mode of the electronic device may continue to be detected. When the audio playback mode is the non-earphone mode, the embodiment of the present application may also include the following steps: when the electronic device is in the non-earphone mode, obtain the distance between the electronic device and the user; adjust the operating frequency of the charge pump to correspond to the distance the second target frequency.

When the wireless communication unit is in working condition, the components in the hardware circuit of the electronic device are affected by the jump in the power required by the load, and will emit noise. When the audio playback component is in non-earphone mode, in order to reduce the impact of noise on the user, the operating frequency of the charge pump can be adjusted according to the preset mapping relationship between the operating frequency and distance. For example, when the distance is smaller, the distance between the electronic device and the user is closer. Therefore, the operating frequency of the charge pump can be increased accordingly.

In some embodiments, a distance sensor may be configured in the electronic device. Alternatively, the distance sensor may be a radar sensor, a laser sensor, an acoustic wave sensor, etc., which are not specifically limited here. Based on distance sensing, the distance between the electronic device and the user can be obtained. Optionally, the electronic device can also be configured with an attitude detection sensor, such as a gyroscope and other detection elements. When acquiring electronic equipment and Before determining the distance between users, the posture information of the electronic device can also be detected to determine whether the user is using the electronic device. If it is determined that the user is using an electronic device, the distance between the electronic device and the user can be obtained; if the user is not using the electronic device, the distance between the electronic device and the user can be stopped.

In the embodiment of the present application, after learning that the user's audio playback component is in non-earphone mode, the distance between the electronic device and the user is obtained to determine whether to adjust the operating frequency of the charge pump, which is conducive to timely adjustment of the operating frequency of the charge pump. is the second target frequency corresponding to the distance. By adjusting the operating frequency of the charge pump to the second target frequency, the voltage fluctuation range in the hardware circuit can be reduced, thereby preventing components in the hardware circuit from emitting noise due to the impact of power jumps, which can effectively reduce noise and avoid impact on users. .

In some embodiments of the present application, adjusting the operating frequency of the charge pump to the second target frequency corresponding to the distance may specifically include: when the distance is greater than or equal to the first threshold, determining the second target based on the power consumption of the wireless communication unit Frequency; adjust the operating frequency of the charge pump to the second target frequency.

Specifically, the above distance is the distance between the electronic device and the user. The first threshold can be preset according to actual application requirements. When the distance is greater than or equal to the first threshold, it can be considered that the distance between the user and the electronic device is relatively far, and the noise in the hardware circuit has less impact on the user. For example, the first threshold may be 10 centimeters. Therefore, according to the power consumption of the wireless communication unit, the second target frequency is determined, that is, the charge pump is controlled to enter the adaptive operating frequency adjustment mode. For example, in the adaptive operating frequency adjustment mode, the electronic device can adjust the operating frequency of the charge pump according to the power consumption of the wireless communication unit in the wireless communication state.

As a specific example, after the charge pump enters the adaptive operating frequency adjustment mode, the power consumption in the wireless communication unit is obtained. When power consumption becomes large, the target output current of the power supply can be determined based on the change in power consumption. Since the charge pump can control the output current of the power supply, the second target frequency of the charge pump can be determined based on the target output current. Continuing to take the dual-cell power supply in electronic equipment and using a 2:1 step-down charge pump as an example. When the working frequency of the charge pump is higher, the output current of the power supply is larger; when the working frequency of the charge pump is lower, The output current of the power supply is smaller. After the charge pump enters the adaptive working frequency adjustment mode and adjusts the working frequency of the charge pump to the second target frequency, the power consumption of the wireless communication unit in the wireless communication state can be satisfied.

In the embodiment of the present application, the second target frequency can be adaptively determined according to the power consumption of the wireless communication unit, so that when the user is far away from the electronic device, the operating frequency of the charge pump can be reduced, while avoiding noise. At the same time, it can also effectively reduce the power consumption caused by excessively high switching frequency.

In some embodiments of the present application, step 220 may specifically include: when the distance is less than the first threshold and the distance is greater than or equal to the second threshold, adjusting the operating frequency of the charge pump to the second target frequency, the second target frequency equal to the first preset frequency.

Specifically, the second threshold can be preset according to actual application requirements. When the distance is less than the first threshold and the distance is greater than or equal to the second threshold, it can be considered that the distance between the user and the electronic device is relatively close, and the impact of noise in the hardware circuit on the user becomes obvious. For example, the second threshold may be 5 centimeters. At this time, the operating frequency of the charge pump can be directly adjusted to a fixed frequency, such as the first preset frequency. In this way, the power supply can stably output a large current, appropriately compensate the power consumption of the wireless communication unit in the wireless communication state, and avoid noise in the circuit caused by large voltage fluctuations in the circuit.

In some embodiments of the present application, step 220 may further include: when the distance is less than the second threshold, adjusting the operating frequency of the charge pump to the second target frequency, and the second target frequency is equal to the second preset frequency, where, The second preset frequency is greater than the first preset frequency.

Specifically, when the distance is less than the second threshold, it can be considered that the distance between the user and the electronic device is very close. If there is noise in the circuit, it will have a significant impact on the user. At this time, the operating frequency of the charge pump can be directly adjusted to the second preset frequency of the fixed frequency. When the charge pump operates at the second preset frequency, the power supply can stably output a large current, thereby compensating the power consumption of the wireless communication unit in the wireless communication state. Taking a dual-cell power supply in an electronic device and using a 2:1 step-down charge pump as an example, the second preset frequency can be, for example, 450 kHz. In this way, the power supply can stably output a large current.

According to the embodiment of the present application, by adjusting the operating frequency of the charge pump to the second preset frequency, since the power supply can provide sufficient output current, the transient response capability of the power supply can be improved. Thereby reducing the voltage ripple in the hardware circuit and reducing the capacitive sound. Therefore, even if the user is close to the electronic device, the noise can be effectively reduced and the impact on the user is reduced.
