The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.

Those skilled in the art will appreciate that the terminal structure shown in fig. 1 does not constitute a limitation of the terminal device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, and a charging program.

In the terminal shown in fig. 1, the network interface 1004 is mainly used for data communication with the background server; the user interface 1003 is mainly used for data communication with a client (user side); when the terminal is a charging box, the processor 1001 may be configured to call the charging program in the memory 1005 and perform the following operations:

Referring to fig. 2 to 3, the present application proposes a charging box 100, the charging box 100 including: a battery 10; a voltage conversion module 20, wherein the voltage conversion module 20 is connected with the battery 10; a control unit 30, wherein the control unit 30 is connected to the voltage conversion module 20, and the control unit 30 is configured to control the voltage conversion module 20 to convert the output voltage of the battery 10 into a charging voltage matched with the charging information according to the charging information of the headset to be charged; and a charging unit connected to the voltage conversion module 20, the charging unit being configured to output the charging voltage.

It should be noted that, in this embodiment, the charging boxes of the existing TWS earphone and ANC earphone are both provided with a rechargeable lithium battery, and meanwhile, a charging circuit is provided inside the earphone, and when the charging box charges the earphone, 3.7V of the internal lithium battery needs to be boosted to 5.0V of the standard USB output voltage, and then the earphone needs to be charged. However, the charging box has the problem of low conversion efficiency in the process of boosting the 3.7V of the lithium battery to 5V, and the charging box can boost the 3.7V to only 4.2-4.3V, so that the charging box has higher circuit efficiency than the common charging box when boosting the 3.7V to 5V. In addition, the charging circuit of the earphone needs to convert the 5V voltage input by the charging box into the charging voltage (generally 2.8V-4.2V) required by the battery, and then the lithium battery is charged by constant current and constant voltage. However, in the process of converting the 5V voltage into the 2.8V-4.2V voltage, the charging circuit inside the earphone generates electric energy loss. Since the in-ear type and semi-in-ear type TWS and ANC earphones are small in size and narrow in internal space, linear voltage reduction and stabilization are generally adopted, and when the external 5V is converted into 2.8V-4.2V, the maximum theoretical electric energy conversion efficiency is only 56% -84%. Therefore, the above-mentioned exemplary earphone charging method has two problems, for the charging box, 3.7V of the built-in lithium battery needs to be boosted to 5V to charge the earphone, resulting in low efficiency of the voltage conversion circuit; for the earphone, the 5V needs to be converted into 2.8-4.2V to charge the battery in the earphone, which causes power loss and low conversion efficiency of the charging circuit. And this embodiment real-time supervision earphone battery charging current is normal to the charging voltage of dynamic adjustment output makes the charging voltage of output be higher than the voltage of treating the rechargeable battery, thereby makes earphone battery charging current normalization, makes the charging voltage of charging box 100 output minimize again, improves the efficiency of charging box 100 voltage conversion circuit and earphone charging circuit then.

Specifically, the charging box 100 houses a battery 10, the battery 10 is used for supplying power to the voltage conversion module 20 and the control unit 30, when charging is started, the control unit 30 outputs a control signal to the voltage conversion module 20, the voltage conversion module 20 converts the 3.7V voltage provided by the battery 10 into a 5.0V voltage according to the control signal, and the charging unit outputs the 5.0V voltage to the earphone to be charged. In the charging process, the control unit 30 obtains charging information of the earphone to be charged in real time, the charging information at least includes one of charging voltage and charging current, and after the charging current and the charging voltage in the earphone to be charged stably reach preset values, the control unit 30 gradually reduces the charging voltage output by the voltage conversion module 20, so that the charging voltage output by the voltage conversion module 20 is gradually reduced from 5.0V. When the charging voltage output by the voltage conversion module 20 is decreased, it is monitored whether the charging current of the earphone to be charged is decreased, if not, the charging voltage output by the voltage conversion module 20 is continuously decreased until the charging current of the earphone to be charged is slightly decreased, at this time, the control unit 30 controls the voltage conversion module 20 to slightly increase the output charging voltage, so that the charging current is restored to a preset normal value, and the earphone battery is stably charged. During charging, as the voltage of the battery of the earphone to be charged increases, the charging current may decrease, and at this time, the control unit 30 controls the voltage conversion module 20 to gradually increase the output charging voltage. The output charging voltage is adjusted in the above way, so that in the constant current charging stage of the earphone battery, the charging current is not lower than the preset rated current value, and in the constant voltage charging stage of the earphone battery, a fixed voltage which is only slightly higher than the earphone battery is also output (the voltage just reaches the voltage required by charging the earphone battery after the line loss and the normal loss of the charging circuit in the earphone), thereby avoiding the excessive voltage (5V output by a common charging box) output by the voltage conversion module 20 from being output to the charging circuit of the earphone, and the excessive electric energy loss in the process of reducing the voltage to 4.2V by the charging circuit of the earphone and then charging the earphone battery. When the earphone battery can be charged normally, the voltage conversion module 20 automatically adjusts the voltage supplied to the earphone charging circuit according to the difference between the line loss of the charging box 100 and the normal loss of the charging circuit inside the earphone, thereby improving the charging efficiency of the charging box 100 and the whole earphone.

Further, referring to fig. 2 to 3, the charging box 100 further includes: the detection module 50 is connected with the control unit 30 and the charging unit, and the detection module 50 is used for detecting charging information of the earphone to be charged; or a receiving module is arranged in the charging box 100, and the receiving module is used for receiving charging information sent by the earphone to be charged.

It should be noted that, in this embodiment, there are two ways for the charging box 100 to obtain the charging information of the headset to be charged, in the way 1, the charging information of the headset to be charged is detected by the detection module 50 in the charging box 100, wherein the detection module 50 is connected to the charging unit, further, the detection module 50 is further connected to the voltage conversion module 20 and the control unit 30 respectively, the detection unit sends the detected charging information to the control unit 30, so that the control unit 30 executes a control operation according to the charging information, and in addition, the detection module 50 is further configured to process the charging voltage output by the voltage conversion module 20 and output the processed charging voltage to the charging unit. The method 2 is to receive charging information sent by the earphone to be charged through a receiving unit in the charging box 100, wherein in the method 2, a control unit inside the earphone to be charged detects a battery charging voltage and a charging current of the earphone in real time, a continuously changing Analog signal is converted into a discrete digital signal through a digital-to-Analog converter (ADC), that is, the charging voltage and the charging current are converted into digital signals, the digital signals are encoded to obtain an encoded signal, and the encoded signal is sent to the control unit 30 of the charging box 100 through a 5V interface for charging the earphone. The charging information of the headset to be charged can be acquired in real time through the detection module 50 and the receiving module in the charging box 100, so that the output charging voltage can be adjusted in time according to the charging information.

Further, referring to fig. 2 to 3, the charging unit includes: a charging circuit 41, wherein the charging circuit 41 is connected with the detection module 50; one end of the charging interface 42 is connected with the charging circuit 41, the other end of the charging interface 42 is connected with the earphone to be charged, and the charging interface 42 is used for outputting the charging voltage to the earphone to be charged; the charging interface is also used for sending the charging information of the earphone to be charged to the charging circuit.

It should be noted that, in this embodiment, the charging unit includes a charging circuit 41, and the charging circuit 41 is connected to the detection module 50 and is used for further processing the charging voltage output by the detection module 50; one end of the charging interface 42 is connected to the charging circuit 41, the other end of the charging interface is connected to the earphone to be charged, and the charging interface 42 is configured to send the charging voltage output by the charging circuit 41 to the earphone to be charged, so as to charge the earphone to be charged. Meanwhile, the charging interface 42 also transmits the coded signal of the control unit inside the earphone to the control unit 30 inside the charging box 100, and the control unit 30 processes the coded signal and outputs accurate voltage and current for charging the earphone.

Referring to fig. 4, fig. 4 is a schematic flowchart of a charging method according to an embodiment of the present application.

While embodiments of the charging method are provided in the present application, it should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.

The charging method is applied to the charging box 100, and the method comprises the following steps:

step S10, acquiring charging information of the earphone to be charged, wherein the charging information at least comprises one of charging voltage and charging current;

in this embodiment, the charging box 100 obtains the charging information of the earphone to be charged in two ways, one is to directly detect the charging information of the charging earphone through the detection module 50 in the charging box 100, the other is to receive the coded signal sent by the earphone to be charged, and obtain the charging information in the earphone to be charged according to the coded signal, wherein the coded signal is obtained by the earphone to be charged by encoding the currently detected charging information, specifically, the control unit in the earphone to be charged detects the charging voltage and the charging current of the battery of the earphone in real time, converts the charging voltage and the charging current into digital signals through the digital-to-analog converter or the analog-to-digital converter, and encodes the digital signals to obtain the coded signal, and sends the coded signal to the control unit 30 of the charging box 100 through the 5V interface for charging the earphone to be charged, wherein the earphone to be charged sends the coded signal to the charging box 100 in real time, so that the charging box 100 can know the current charging situation in time, for example, the earphone to be charged sends a coding signal to the charging box 100 every set time (for example, 10-100 mS).

A step S20 of controlling the voltage conversion module 20 of the charging box 100 to convert the output voltage of the battery 10 into a charging voltage matching the charging information according to the charging information;

referring to fig. 5, in the present embodiment, when charging is started, the control unit 30 outputs a control signal to the voltage conversion module 20, the voltage conversion module 20 converts the 3.7V voltage provided by the battery 10 into a 5.0V voltage according to the control signal, and the charging unit outputs the 5.0V voltage to the headset to be charged. In the charging process, the control unit 30 obtains charging information of the headset to be charged in real time, and when the charging information meets a first set condition, the control unit 30 controls the voltage conversion module 20 to reduce the charging voltage, specifically, when the charging current in the headset to be charged reaches a preset value (e.g., 20-60mA) and the charging voltage reaches a preset value (e.g., 3.0V-3.8V), the control unit 30 gradually reduces the charging voltage output by the voltage conversion module 20, so that the charging voltage output by the voltage conversion module 20 is gradually reduced from 5.0V, wherein the voltage is reduced by a certain amplitude (e.g., 1-5mV) each time. And after the charging voltage is reduced each time, immediately detecting whether the charging current is reduced, if the charging current is not reduced, reducing the charging voltage again, and when the charging current is detected to be reduced by a certain amplitude (such as 0.5-2mA), stopping reducing the voltage, and increasing the voltage by a certain amplitude (such as 1-5mV), so that the charging current is restored to the original preset level. That is, at the beginning of charging, the voltage conversion module 20 converts the 3.7V voltage into the 5.0V voltage and outputs the voltage, and after the charging current and the charging voltage in the earphone to be charged stably reach the preset values, the voltage conversion module 20 converts the 3.7V voltage into the voltage (generally 2.8-4.2V) required by charging the battery of the earphone and outputs the voltage after multiple descending adjustment, detection, fine adjustment and promotion. At this time, the conversion efficiency of converting 3.7V voltage into 2.8-4.2V voltage is higher than that of a common charging box which converts 3.7V voltage into 5.0V voltage to supply to the earphone, and the earphone charging circuit converts 5V into 2.8-4.2V voltage to charge the earphone, that is, the conversion efficiency of the voltage conversion circuit of the charging box 100 and the charging electric energy conversion efficiency of the earphone are improved.

In an embodiment, when the charging voltage output by the voltage conversion module 20 decreases, the control unit 30 monitors in real time whether the charging current of the earphone to be charged decreases, if the charging current does not decrease, that is, the current charging current is not lower than the preset value (e.g., 20-60mA), the control unit 30 continues to decrease the charging voltage output by the voltage conversion module 20 until the charging current of the earphone to be charged decreases slightly, that is, the current charging current is lower than the preset value (e.g., 20-60mA), and at this time, the control unit 30 controls the voltage conversion module 20 to slightly increase the output charging voltage, so that the charging current recovers to the normal preset value (e.g., 20-60mA), and the earphone battery is stably charged, and the output charging voltage is the voltage corresponding to the moment when the charging current reaches the preset value. For example, in the process of decreasing the charging voltage, if the voltage decreases to 4.2V and the charging current does not decrease, the output charging voltage continues to decrease, and when the voltage decreases to 4.1V and the charging current decreases a little (for example, by 0.5 to 2mA), the output charging voltage does not continue to decrease, but the output charging voltage (for example, by 1 to 5mV) is increased in a small range, so that the charging current returns to the normal preset value.

In an embodiment, in the process of charging with the voltage corresponding to the moment when the charging current reaches the set current, the charging current may decrease as the voltage of the battery of the earphone to be charged increases, and at this time, the control unit 30 controls the voltage conversion module 20 to gradually increase the output charging voltage. If the charging current is detected to drop, the charging voltage output currently is increased by a certain amplitude (e.g. 1-5mV each time) so as to enable the charging current to recover the normal preset value for charging.

The output charging voltage is adjusted in the above way, so that in the constant current charging stage of the earphone battery, the charging current is not lower than the preset rated current preset value, and in the constant voltage charging stage of the earphone battery, a fixed voltage which is only slightly higher than the earphone battery is also output (the voltage just reaches the voltage required by charging the earphone battery after the line loss and the normal loss of the charging circuit in the earphone), thereby avoiding the excessive voltage from being converted into redundant heat energy after the voltage of the voltage conversion module 20 is reduced, enabling the earphone battery to be charged normally, and simultaneously, according to the difference between the line loss of the charging box 100 and the normal loss of the charging circuit in the earphone, the voltage conversion module 20 automatically adjusts the voltage supplied to the charging circuit in the earphone, thereby improving the voltage conversion efficiency of the charging box 100 and the charging efficiency of the whole earphone. For example, the battery of the earphone to be charged is 3.3V, the charging box 100 outputs a charging voltage (e.g. 3.4V-3.5V) slightly higher than 3.3V, and keeps a certain voltage difference with the voltage of the battery of the earphone to be charged, and the charging circuit can stably work, so that the voltage conversion efficiency of the charging box 100 is improved, e.g. the voltage is increased from 3.7V to 4.2V, and the voltage is increased from 3.7V to 5.0V as compared with the common earphone charging box; the charging efficiency of the charging circuit in the earphone to be charged on the battery is also improved, for example, the battery of the earphone to be charged is 3.9V, the charging box 100 only outputs a voltage (for example, 4.0-4.1V) slightly higher than 3.9V to the charging circuit of the earphone to be charged, the charging circuit of the earphone to be charged then reduces the voltage of 4.0-4.1V to 3.9V to charge the battery of the earphone, compared with other charging boxes 100, the charging circuit of the earphone firstly increases the voltage of 3.7V to 5.0V, and then reduces the voltage of 5V to 3.9V to charge the battery with high efficiency. If the voltage of the battery 10 of the charging box 100 is 4.0V and the voltage of the battery of the earphone to be charged is 3.3V, the charging box 100 outputs the voltage slightly higher than 3.3V (such as 3.4V-3.5V) to charge the battery of the earphone by adopting a switch type voltage reduction mode, so that the charging efficiency can be further improved.

It should be noted that the charging voltage, the charging current, and the voltage drop and rise amplitude of each charging can be set in an optimal manner according to the factors such as battery characteristics, circuit characteristics, cost, etc., or according to the type of the earphone, which is not limited herein.

Step S30, the charging circuit 41 of the charging box 100 is controlled to output the charging voltage to the headset to be charged.

In this embodiment, after the voltage conversion module 20 of the charging box 100 outputs the converted charging voltage to the detection module 50, the charging voltage is output to the earphone to be charged through the charging circuit 41 and the charging interface 42, wherein the charging box 100 is connected to the earphone to be charged through the charging interface 42.

In this embodiment, by acquiring charging information of the earphone to be charged, the charging information at least includes one of a charging voltage and a charging current; controlling the voltage conversion module 20 of the charging box 100 to convert the output voltage of the battery 10 into a charging voltage matched with the charging information according to the charging information; the charging circuit of the charging box 100 is controlled to output a charging voltage to the headset to be charged. Due to the charging circuit in the earphone, when the built-in battery is charged, certain voltage loss exists, and when the battery is charged, certain internal resistance exists. Therefore, whether earphone battery charging current is normal is monitored in real time, the output charging voltage is dynamically adjusted, the output charging voltage is higher than the voltage of a battery to be charged, the earphone battery charging current is normalized, the charging voltage output by the charging box 100 is minimized, and then the efficiency of the charging box 100 voltage conversion circuit and the earphone charging circuit is improved.
