Description

Technical Field

[0001] The present application relates to the field of terminals, and more specifically, to a method for wireless reverse charging of electronic devices and electronic devices. Background Art

[0002] With the development of electronic devices, more and more electronic devices support wireless charging. Moreover, some electronic devices not only support wireless charging for themselves, but also support wireless charging for other electronic devices. This function of an electronic device charging other electronic devices using wireless charging is called reverse wireless charging or wireless reverse charging.

[0003] Currently, before an electronic device can wirelessly charge another electronic device, the user must manually turn on the wireless reverse charging switch on the electronic device. Users may often forget to turn on this switch, resulting in reverse charging failure and a reduced user experience. Summary of the Invention

[0004] The present application provides a method and electronic device for wireless reverse charging of an electronic device, which can automatically enable the wireless reverse charging function on an electronic device that supports the wireless reverse charging function (also referred to as an electronic device that provides power or a second electronic device), avoiding the user from manually enabling the function on the second electronic device, thereby improving the user experience.

[0005] In a first aspect, a method for wireless reverse charging of an electronic device is provided, the method comprising: receiving a first operation by a user on a button on a first electronic device, wherein the first electronic device supports a wireless charging function; in response to the first operation, the first electronic device sends first indication information, the first indication information being used to instruct: automatically turning on the wireless reverse charging function; and when a second electronic device receives or detects the first indication information, in response to the first indication information, the second electronic device automatically turns on the wireless reverse charging function. The second electronic device supports the wireless reverse charging function and is configured to wirelessly reverse charge the first electronic device.

[0006] The first aspect provides a method for wireless reverse charging of electronic devices. By setting a button on a first electronic device being wirelessly reverse charged, a user pressing the button triggers the charged electronic device to send a first indication message. The first indication message is used to instruct the electronic device to automatically turn on the wireless reverse charging switch, that is, automatically enable the wireless reverse charging function. When a second electronic device (which supports the wireless reverse charging function and is used to wirelessly reverse charge the first electronic device) receives or detects the first indication message, the wireless reverse charging function is automatically enabled. The second electronic device can then wirelessly reverse charge the first electronic device, eliminating the need for the user to manually enable the function on the main electronic device and improving the user experience.

[0007] Exemplarily, the first electronic device may send the first indication information in a unicast or broadcast manner.

[0008] For example, if sent in the form of unicast (or multicast), the first electronic device can send a first indication message to one or more second electronic devices, and the first indication message is used to instruct: one or more second electronic devices to automatically turn on the wireless reverse charging function. In this way, one or more second electronic devices can receive the first indication message. The first indication message is sent in the form of unicast. Since the second electronic device that receives the first indication message is certain, the effectiveness of the first indication message and the success rate of receiving it can be improved, thereby improving the success rate of the second electronic device automatically turning on the wireless reverse charging function.

[0009] Illustratively, the first electronic device may establish a Bluetooth connection with one or more second electronic devices respectively, and the first electronic device may send the first indication information to the one or more second electronic devices respectively through the Bluetooth communication connection.

[0010] For another example, if the first electronic device is broadcasting, the first instruction information can be broadcasted via Bluetooth. The first instruction information is used to instruct: automatically turn on the wireless reverse charging function. After the second electronic device detects the first instruction information, it automatically turns on the wireless reverse charging function. Sending the first instruction information via Bluetooth broadcast can reduce the communication resources and complexity required to send the first instruction information, making it easier to implement and reducing communication resource consumption.

In this implementation, if the earphone case does not have communication functionality with a second electronic device, the earphone case can transmit the first instruction information via the Bluetooth headset in response to the user's first operation, and the second electronic device automatically enables the wireless reverse charging function upon receiving or detecting the first instruction information. Furthermore, this allows the second electronic device to automatically enable the wireless reverse charging function even if the earphone case does not have communication functionality with the second electronic device, further improving the user experience.

As long as the method provided in the embodiment of the present application can be executed by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be an electronic device, or a functional module in an electronic device that can call a program and execute the program.

[0098] In addition, various aspects or features of the present application can be implemented as methods, devices or products using standard programming and / or engineering techniques. The term "product" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier or medium. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks or magnetic tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks or key drives, etc.). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing and / or carrying instructions and / or data.

[0099] With the development of electronic devices (such as smartphones, tablets, and Bluetooth headsets), more and more electronic devices support wireless charging. The electronic devices are charged through electromagnetic induction between them and wireless charging devices (such as wireless chargers, wireless charging pads, and wireless charging bases), eliminating the need for charging cables and greatly improving the user experience.

[0100] With the development of technology, some electronic devices can not only charge themselves wirelessly, but also charge other electronic devices wirelessly. Of course, other electronic devices also need to support wireless charging. For example, some smartphones can use wireless charging to charge smart watches, smart bracelets, Bluetooth headsets, etc. The function of an electronic device charging other electronic devices using wireless charging is called reverse wireless charging or wireless reverse charging.

[0101] Currently, before an electronic device performs reverse wireless charging, a user needs to manually turn on a wireless reverse charging switch on the electronic device before wireless charging can be performed on other electronic devices.

[0102] For example, assuming that the electronic device is a smartphone, it is necessary to reverse wirelessly charge a true wireless stereo (TWS) headset. TWS headsets are usually equipped with an earphone box (or it can also be called an earphone charging box, charging box, etc.). The earphone box can not only be used to store and charge the TWS headset, but also send relevant instructions to the TWS headset through communication to achieve functions such as pairing and connection of the TWS headset. For example, the earphone box can be connected to the TWS headset with a pogo pin connector to charge the TWS headset and send relevant instructions to the TWS headset. The current charging methods for the earphone box include wired charging and wireless charging.

[0103] For example, Figure 1 The figure shows a schematic diagram of a TWS headset and a headset box. Figure 1 The picture a in the figure shows a TWS headset. Figure 1 The earphone box is shown in Figure b, and the earphone box is in a closed (or shut down) state. Figure 2 The following is a schematic diagram of a TWS headset and headset box. Figure 2 In the example shown, the earphone box is in an unboxing (or opened) state.

[0104] It is understandable that the reverse wireless charging of TWS earphones by smartphones is actually the reverse wireless charging of earphone boxes by smartphones. Figure 3As shown, before the smartphone can reverse wirelessly charge the earphone box, the user needs to manually turn on the "wireless reverse charging" switch on the smartphone's display interface, and then place the earphone box on the smartphone's wireless charging coil area. Figure 4 As shown, the wireless charging coil area of ​​a smartphone is generally located on the back of the phone (the back of the phone can be understood as the non-display surface of the phone, or the opposite side of the display surface (i.e., the front of the phone)). That is to say, after the user manually turns on the "wireless reverse charging" switch of the smartphone, the earphone box is placed on the back of the phone, so that the smartphone can reverse wirelessly charge the earphone box. It can be understood that during the process of reverse wireless charging of the earphone box by the smartphone, the TWS earphones can be stored in the earphone box or not.

[0105] However, because users must manually turn on the wireless reverse charging switch on an electronic device before wireless reverse charging can be used for other electronic devices, users may often forget to turn on this switch, resulting in reverse charging failure. For example, a user may place an earphone case on the back of a phone to start reverse wireless charging, but forget to turn on the switch. As a result, the charging indicator on the earphone case does not light up, and the user may feel that reverse wireless charging is not working, which reduces the user experience.

[0106] In view of this, the present application provides a method for wireless reverse charging of an electronic device, by setting a button on the electronic device being wirelessly reverse charged (a first electronic device, the first electronic device supports a wireless charging function), and after the user presses and clicks the button (i.e., performs a first operation), the first electronic device can be triggered to send a first indication message, and the first indication message is used to indicate that a switch for automatically turning on wireless reverse charging is automatically turned on, i.e., to indicate that the wireless reverse charging function is automatically turned on. When a second electronic device (the electronic device supports the wireless reverse charging function and is used to perform wireless reverse charging for the first electronic device) receives or detects the first indication message, the wireless reverse charging function is automatically turned on. After that, the second electronic device can perform wireless reverse charging for the first electronic device, avoiding the user manually turning on the function on the second electronic device, thereby improving the user experience.

[0107] Optionally, the button on the first electronic device may be a physical button. Of course, this button may also be a touch-sensitive button, which is not limited in the embodiment of the present application.

[0108] For example, the first operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0109] It should be understood that in the embodiment of the present application, the second electronic device can be any electronic device with a reverse wireless charging function, including, for example: a smartphone, a personal computer (PC), a tablet computer, a folding screen device (such as a folding screen mobile phone), a large screen device, a car computer, etc.

[0110] The electronic device being wirelessly reverse charged (or also referred to as the first electronic device) can be any electronic device with a wireless charging function, including, for example, a smartphone, a wearable device (such as a smartwatch, a Bluetooth headset, a smart bracelet, or a headphone box), etc. The specific form of the first electronic device and the second electronic device is not limited in the embodiments of the present application.

[0111] It can be understood that the second electronic device can be used to perform wireless reverse charging for the first electronic device.

[0112] For example, the first electronic device and the second electronic device can communicate with each other via Bluetooth, near field communication (NFC), wireless-fidelity technology ( ) for communication, or using cellular technology (Cellular), etc. The present application embodiment is not limited here.

[0113] It can be understood that in the embodiments of the present application, regardless of the state of the first electronic device, for example, whether the first electronic device is powered on, powered off, in sleep mode, or in working mode, the user can perform a first operation on a button on the first electronic device (for example, the user clicks or presses a button once or multiple times). After the first electronic device receives the user's first operation, it can trigger the first electronic device to send a first indication message. The first indication message is used to indicate: automatically turn on the wireless reverse charging function. When the second electronic device receives or detects the first indication message, it automatically turns on the wireless reverse charging function in response to the first indication message. This avoids the user having to manually turn on the function on the second electronic device, thereby improving the user experience.

[0114] For example, if the first electronic device is powered on or in operation, and a communication connection (e.g., a Bluetooth connection, a Wi-Fi connection, etc.) has been established between the first electronic device and the second electronic device, in this case, the user can perform a first operation on a button on the first electronic device. After the first electronic device receives the user's first operation, it can trigger the first electronic device to send a first indication message to the second electronic device via the communication connection. The first indication message is used to instruct the second electronic device to automatically turn on the wireless reverse charging function. In response to the first indication message, the second electronic device automatically turns on the wireless reverse charging function.

[0115] For another example, if the first electronic device is powered on or in working state, and a communication connection has not been established between the first electronic device and the second electronic device, in this case, the user can perform a first operation on a button on the first electronic device. After the first electronic device receives the user's first operation, one possible implementation method is: the first operation can trigger: establishing a communication connection between the first electronic device and the second electronic device, and the first electronic device sends a first indication message to the second electronic device through the communication connection, and the first indication message is used to instruct: the second electronic device to automatically turn on the wireless reverse charging function; or another possible implementation method is: the first operation can trigger the first electronic device to send a first indication message (sent in the form of a broadcast), and the first indication message is used to instruct: automatically turn on the wireless reverse charging function. After receiving or detecting the first indication message, the second electronic device can automatically turn on the wireless reverse charging function in response to the first indication message.

[0116] For another example, if the first electronic device is in a shutdown or dormant state, in this case, the user can perform a first operation on a button on the first electronic device. After the first electronic device receives the user's first operation, it can trigger: the first electronic device switches from a shutdown or dormant state to a power-on or working (activation) state, a communication connection is established between the first electronic device and the second electronic device, and the first electronic device sends a first indication message to the second electronic device through the communication connection. The first indication message is used to instruct: the second electronic device to automatically turn on the wireless reverse charging function. The second electronic device automatically turns on the wireless reverse charging function in response to the first indication message.

[0117] Of course, if the first electronic device maintains a communication connection with the second electronic device while in sleep mode, the first operation may trigger: the first electronic device switches from sleep mode to working mode, and the first electronic device sends a first indication message to the second electronic device through the communication connection.

[0118] For another example, if the first electronic device is in a powered-off or dormant state, in this case, the user can perform a first operation on a button on the first electronic device. After the first electronic device receives the user's first operation, it can trigger: the first electronic device switches from the powered-off or dormant state to the powered-on or working (activated) state, and the first electronic device sends a first indication message, which is used to instruct: the wireless reverse charging function to be automatically turned on. The second electronic device that receives or detects the first indication message automatically turns on the wireless reverse charging function in response to the first indication message.

[0119] That is to say, in some possible implementations of the present application, the user's first operation may trigger: the first electronic device sends the first indication information; or the first electronic device establishes a Bluetooth connection with the second electronic device, and the first electronic device sends the first indication information through the Bluetooth connection; or the first electronic device is turned on or activated, the first electronic device and the second electronic device establish a Bluetooth connection, and the first electronic device sends the first indication information through the Bluetooth connection; or the first electronic device is turned on or activated, and the first electronic device sends the first indication information.

[0120] Of course, in other possible implementations of the present application, before receiving the first user operation on a key on the first electronic device, the first electronic device may also receive a second user operation on a key on the first electronic device; the second operation may trigger: the first electronic device to establish a Bluetooth connection with the second electronic device; or the first electronic device to be powered on or activated, and the first electronic device to establish a Bluetooth connection with the second electronic device; or the first electronic device to be powered on or activated. Thereafter, the user may perform the first operation on a key on the first electronic device, and upon receiving the first user operation, the first electronic device may trigger: the first electronic device to send the first indication information.

[0121] For example, the second operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0122] Of course, the second operation and the first operation can be continuous operations, for example, the user clicks or presses a button on the first electronic device multiple times (for example, twice). Alternatively, there can be a short interval between the second operation and the first operation. In other words, for the user, the second operation and the first operation can be a single operation as a whole, and this single operation can be: clicking or pressing the button multiple times. Alternatively, the second operation and the first operation can be two separate operations. This embodiment of the present application is not limited here.

[0123] It should be understood that in the embodiment of the present application, when the first electronic device sends the first indication information, it can be sent in a unicast, multicast or broadcast manner.

[0124] For example, if the first electronic device has previously established a communication connection (such as a Bluetooth connection) with one or more second electronic devices, the first electronic device may send the first indication information in a unicast or multicast manner. That is, after the first electronic device receives the user's first operation, it can be triggered: the first electronic device sends the first indication information to one or more second electronic devices through the communication connection. In this case, the first indication information is used to instruct: the second electronic device automatically turns on the wireless reverse charging function. One or more second electronic devices can automatically turn on the wireless reverse charging function in response to the first indication information.

[0125] For another example, if the first electronic device has not previously established a communication connection with other electronic devices, the first electronic device may transmit the first indication information via Bluetooth broadcast. That is, after the first electronic device receives the user's first operation, it may trigger the first electronic device to broadcast the first indication information via Bluetooth. In this case, the first indication information is used to instruct the user to automatically turn on the wireless reverse charging function. The one or more second electronic devices that receive or detect the first indication information may automatically turn on the wireless reverse charging function in response to the first indication information.

[0126] Optionally, if multiple second electronic devices automatically turn on the wireless reverse charging function, the user can place the first electronic device in the wireless charging coil area of ​​a second electronic device (such as a first smartphone) that needs reverse wireless charging according to their needs, thereby performing wireless reverse charging for the first electronic device.

[0127] Optionally, for a second electronic device (such as a tablet computer) that does not need to perform reverse wireless charging for the first electronic device, within a preset time period, if the tablet computer detects that it has not performed reverse wireless charging for the first electronic device, the tablet computer can automatically turn off the wireless reverse charging function, thereby saving power and increasing the usage time of the tablet computer.

[0128] The following describes the method for wireless reverse charging of an electronic device provided by the present application with reference to specific examples.

[0129] In the following examples, reverse wireless charging of a smartphone to a first electronic device is used as an example for explanation, that is, the smartphone is the main electronic device or the second electronic device, and the first electronic device is the electronic device being charged. For example, the first electronic device may include a Bluetooth headset (TWS headset is used as an example for explanation) and an earphone box, and the earphone box supports wireless charging. However, it should be understood that in other implementations of the present application, the main electronic device and / or the electronic device being charged may also be other forms of electronic devices, and the embodiments of the present application are not limited thereto.

[0130] It should also be understood that the following description takes Bluetooth communication or NFC communication between a smartphone and a TWS headset, or between a smartphone and a headset box as an example, but it should be understood that in other implementations of the present application, other communication methods may be used between a smartphone and a TWS headset, or between a smartphone and a headset box, such as using The present invention does not limit the communication.

[0131] Since TWS earphones are usually equipped with an earphone box, a button can be set on the earphone box in the embodiment of the present application. Optionally, this button can be a physical button, that is, the user needs to press this button to trigger the corresponding processing process. Of course, this button can also be a touch button, and the user only needs to touch or click with a finger to trigger the corresponding processing process.

[0132] For example, Figure 5 The figure shows a schematic diagram of a physical button set on the earphone box. The user can press the button with his finger to trigger the earphone box or TWS earphones to send a Bluetooth message to the mobile phone. After the mobile phone receives the Bluetooth message, it can automatically turn on the wireless reverse charging function.

[0133] certainly, Figure 5 This is merely an example and should not limit the embodiments of the present application. For example, in other implementations of the present application, the physical button can be set in other locations or other areas of the earphone box, and the shape of the physical button can also be other shapes (such as a circle, etc.), which are not limited in the embodiments of the present application.

[0134] In some possible implementations, it is assumed that the earphone box does not have Bluetooth functionality and its main function is to store and charge the TWS earphones. In this case, the earphone box may be in a powered-on or powered-off state, and the TWS earphones in the earphone box may also be in a powered-on or powered-off state. These states will be described below. Optionally, in the embodiment of the present application, the powered-off state may also be referred to as a dormant or sleeping state, and the powered-on state may also be referred to as an active state or a working state.

[0135] In the following examples, the method is described by taking TWS earphones, earphone boxes, and smartphones as the execution subjects of the method. As an example and not a limitation, the TWS earphones, earphone boxes, and smartphones in this application may also be chips, chip systems, or processors that support the TWS earphones, earphone boxes, and smartphones to implement the method. The embodiments of this application are not limited here.

[0136] Status 1: The earphone box is powered off or in sleep mode, the TWS earphones are in the earphone box, and the TWS earphones are also powered off or in sleep mode.

[0137] Figure 6 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in state 1. Figure 6 As shown, the method 600 includes:

[0138] S601: The earphone box receives a second operation of a user on a button on the earphone box.

[0139] For example, the second operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0140] S602: In response to the second operation, the earphone box is powered on or activated, and the earphone box controls the TWS earphone to be powered on or activated.

[0141] For example, when a user presses a button on the headset box for the first time, the power supply inside the headset box is connected, and the battery inside the headset box powers up the microcontroller unit (MCU) inside the headset box, causing the MCU inside the headset box to switch from a dormant state to an active state. After the MCU inside the headset box switches from a dormant state to an active state, the MCU inside the headset box begins loading software and other processes. After these processes are completed, the headset box is in the powered-on or activated state.

[0142] Optionally, the earphone box can light up its own indicator light to show the user that the earphone box has been activated.

[0143] Optionally, when the earphone box transitions from a dormant state to an active state, the MCU inside the earphone box can control the earphone box to perform processes such as hardware startup, software loading (boot roader), and button function initialization. After these processes are completed, the earphone box is in an active state, and the earphone box (i.e., the MCU inside the earphone box) can process user commands normally. For example, the earphone box can detect or recognize the user's operation on the button on the earphone box and execute the corresponding instructions or functions corresponding to these operations.

[0144] After the earphone box is activated, since the TWS earphones are stored in the earphone box, the earphone box can control the TWS earphones to change from a dormant state to an active state through the control circuit. For example, the earphone box can control the TWS earphones through the metal contacts between the TWS earphones and the earphone box. In other words, after the earphone box is activated, the earphone box can activate the TWS earphones through the control circuit.

[0145] For example, the MCU in the earphone box can control the TWS earphones to perform hardware startup, software loading (boot roader) and other processing processes. After these processing processes are completed, the TWS earphones are in an activated state.

[0146] That is to say, in state one, the user's second operation on the button on the earphone box is used to trigger: the earphone box is activated, and the earphone box activates the TWS earphones.

[0147] It should be understood that when the TWS headset is activated or started, the Bluetooth of the TWS headset will also enter an activated or working state, so that the TWS headset can establish a Bluetooth connection with the smartphone and establish a Bluetooth transmission channel. In other words, in method 600, "the TWS headset is activated or started" or "the second operation" can trigger "establishing a Bluetooth connection between the TWS headset and the smartphone."

[0148] For example, since the Bluetooth of a smartphone will periodically send paging signals, the Bluetooth of the TWS headset enters the paging scan state after being activated. In this state, the TWS headset can reply to the response information of the smartphone, and the Bluetooth connection link between the TWS headset and the smartphone is established.

[0149] Optionally, in some possible implementations, assuming that there are multiple second electronic devices around the TWS headset (i.e., within the Bluetooth signal coverage range of the TWS headset), if the TWS headset has previously been paired or connected to an electronic device among the multiple second electronic devices (for example, a first smartphone) through Bluetooth, the TWS headset automatically prioritizes Bluetooth connection with the first smartphone to establish a Bluetooth transmission channel.

[0150] Optionally, in some other possible implementations, assuming that there are multiple second electronic devices around the TWS headset, if the TWS headset has not been paired or connected with these multiple second electronic devices before, or if the TWS headset has been paired or connected with multiple (at least two) second electronic devices before, one possible implementation is: the user can choose to connect to the TWS headset through Bluetooth on the Bluetooth connection interface of a second electronic device (for example, a first smartphone) that needs to perform reverse wireless charging for the headset box, and establish a Bluetooth transmission channel. Another possible implementation is: the TWS headset can also be connected to multiple second electronic devices through Bluetooth, so that the TWS headset can establish Bluetooth transmission channels with multiple second electronic devices respectively.

[0151] Of course, if there is only one second electronic device around the TWS headset, regardless of whether the electronic device has been paired or connected to the TWS headset through Bluetooth before, the TWS headset automatically connects to the electronic device through Bluetooth and establishes a Bluetooth transmission channel.

[0152] S603: The earphone box receives a first operation of a button on the earphone box by the user.

[0153] For example, the first operation may be that the user clicks or presses a button on the earphone box once. Of course, in other implementations of the present application, the second operation may also be that the user clicks or presses the button multiple times.

[0154] S604, in response to the first operation, the earphone box sends a second indication message to the TWS earphone, where the second indication message is used to indicate: the TWS earphone instructs the electronic device to automatically turn on the wireless reverse charging function.

[0155] Correspondingly, the TWS headset receives the second indication information.

[0156] For example, since the earphone box is connected to the TWS earphone via a pogo pin connector, the earphone box can send the second indication information to the TWS earphone via the pogo pin connector, that is, the second indication information is directional. In other words, the second indication information can be understood as being sent in unicast form.

[0157] Since the earphone box does not determine which electronic device or electronic devices the TWS earphones will instruct to automatically turn on the wireless reverse charging function, the second indication information sent by the earphone box to the TWS earphones is used to indicate that the TWS earphones instruct the electronic device to automatically turn on the wireless reverse charging function. It can be understood that the "electronic device" indicated by the TWS earphones includes: one or more electronic devices that can receive the first indication information sent by the TWS earphones, such as a smartphone.

[0158] For example, after the user clicks or presses the button once or multiple times (i.e., the first operation), the MCU in the earphone box detects the user's first operation. Since the MCU in the earphone box has previously stored a mapping relationship or correspondence between the user's operation on the button and the corresponding instruction, after the MCU in the earphone box detects the user's operation on the button, according to the instruction corresponding to the operation, the MCU in the earphone box can send the second indication information to the TWS earphone.

[0159] For example, when the earphone box is in an activated state or after it is started, each press or click of a button on the earphone box by the user is used to trigger: the earphone box sends the second indication information to the TWS earphones.

[0160] For example, the MCU in the earphone box transmits the information corresponding to the key action (i.e., the first operation) recorded in the cache (for example, "0X70", which indicates that reverse wireless charging is turned on) to the TWS earphones through the communication link between the earphone box and the TWS earphones.

[0161] Exemplarily, the MCU in the earphone box can send the second indication information to the TWS earphone through the control circuit.

[0162] Of course, the above-mentioned second operation and first operation can be continuous operations. For example, the user continuously clicks or presses the button on the earphone box multiple times (for example, twice). These multiple clicks or presses are used to trigger: the earphone box is turned on, the earphone box activates the TWS earphones, and the MCU in the earphone box sends a second indication message to the TWS earphones. Alternatively, there can be a short interval between the second operation and the first operation, such as an interval of 1 second. That is to say, for the user, the second operation and the first operation can be one operation as a whole, and this operation can be: clicking or pressing the button multiple times. Alternatively, the second operation and the first operation can be two separate operations. The embodiments of the present application are not limited here.

[0163] S605. In response to the second indication information, the TWS headset sends a first indication information to the smartphone, where the first indication information is used to instruct the smartphone to automatically turn on the wireless reverse charging function.

[0164] Correspondingly, the smartphone receives the first indication information.

[0165] Exemplarily, the TWS headset can send the first indication information to the mobile phone through the Bluetooth transmission channel between the TWS headset and the smart phone.

[0166] S606: The smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0167] For example, the smartphone automatically turns on the “wireless reverse charging” switch according to the first instruction information.

[0168] It is understandable that the TWS headset can send a first indication message to one or more second electronic devices that have been connected to it by Bluetooth (i.e., a Bluetooth transmission channel has been established). After receiving the first indication message, the one or more second electronic devices connected to the TWS headset by Bluetooth automatically turn on the wireless reverse charging function. If multiple second electronic devices automatically turn on the wireless reverse charging function, the user can place the earphone box in the wireless charging coil area of ​​a second electronic device (such as a first smartphone) that needs reverse wireless charging according to their needs, thereby performing wireless reverse charging for the earphone box.

[0169] Optionally, for electronic devices that do not need reverse wireless charging for the headphone box, within a preset time period, if the electronic device detects that it has not performed reverse wireless charging for the headphone box, the electronic device can automatically turn off the wireless reverse charging function, thereby saving power and increasing the usage time of the electronic device.

[0170] Optionally, after the smartphone automatically turns on the wireless reverse charging function, the smartphone can notify the user that the wireless reverse charging function has been turned on by vibration, ringtone, voice prompt or displaying a prompt message on the interface, so that the wireless reverse charging function is already in the turned-on state, thereby improving the user experience.

[0171] Optionally, in some possible implementations, after the smartphone automatically turns on the wireless reverse charging function, the user can place the earphone box containing the TWS earphones on the back of the smartphone, for example, Figure 4 As shown, the smartphone can be used to reverse wirelessly charge the earphone box or TWS earphones.

[0172] Alternatively, in some other possible implementations, during the execution of method 600, the user may also place the earphone box containing the TWS earphones on the back of the smartphone. That is, during the entire execution of method 600, the earphone box containing the TWS earphones is located on the back of the smartphone.

[0173] Through the above method, a button is set on the earphone box, and the user's second operation on the button can trigger: the earphone box changes from a dormant state to an active state, and the earphone box activates the TWS earphones. After that, the user's first operation on the button can trigger the earphone box to send a signal to the smartphone through the TWS earphones. After receiving the signal, the smartphone automatically turns on the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, avoiding the user manually turning on the function on the smartphone, and improving the user experience. In addition, through the first operation triggering: the earphone box sends the second indication information to the TWS earphones, and the TWS earphones sends the first indication information to the smartphone, it can avoid the earphone box continuously sending the second information and the TWS earphones continuously sending the first indication information, thereby reducing the power consumption of the earphone box and the TWS earphones, and increasing the usage time of the earphone box.

[0174] Optionally, as a possible implementation, in method 600, the earphone box may be in a closed (or turned off) state. That is, in some possible implementations, if the earphone box is in the closed (or turned off) state, it means that the earphone box is in a powered-off or dormant state.

[0175] Optionally, as another possible implementation, in method 600, the earphone box may also be in an unboxed (or opened) state.

[0176] Optionally, as a possible implementation, if the earphone box is in a closed (or powered off) state, then in method 600, S601 may be replaced by: the user opens the earphone box. That is, the second operation may be the user opening or unpacking the earphone box, and the second operation is used to trigger: the earphone box is powered on or activated, and the earphone box activates the TWS earphones.

[0177] Optionally, as a possible implementation method, in the above-mentioned state one, the user may also only perform the first operation or the second operation on the button on the earphone box. In this case, the first operation or the second operation of the user on the button on the earphone box is used to trigger: the earphone box is activated, the earphone box activates the TWS earphones, the earphone box sends the second indication information to the TWS earphones, and the TWS earphones send the first indication information to the smartphone. After the first operation or the second operation is completed, the earphone box can be activated, the earphone box activates the TWS earphones, and the earphone box can send the second indication information to the TWS earphones. The TWS earphones can respond to the second indication information and send the first indication information to the smartphone, and the smartphone can automatically turn on the wireless reverse charging function according to the first indication information. Optionally, the first operation or the second operation can be that the user clicks or presses the button on the earphone box once or multiple times.

[0178] For example, Figure 7 An example is shown in Figure 6 In the method shown, the schematic diagram of the internal circuit control of the earphone box and TWS earphone is as follows Figure 7 As shown, the earphone box may include: a battery, a power manager (charger), an MCU, and a control circuit. The power manager (charger) is connected to the battery, the MCU, and the control circuit.

[0179] exist Figure 7 In the example shown, the earphone box is initially in a dormant state. When the user presses the button on the earphone box for the first time (i.e., when performing the second operation), the button on the earphone box triggers the power manager (charger) to power on. After the power manager works, it connects the battery and the MCU, controls the battery to power on the MCU, and after powering on, the MCU is in a normal working state and starts loading software, starting hardware, initializing buttons, etc., to control the earphone box to be in a working or active state. At the same time, the MCU activates the TWS earphones through the control circuit, and the TWS earphones start to start and start to establish a Bluetooth connection with the smartphone. When the user presses the button on the earphone box for the second time (i.e., when performing the first operation), the MCU records the button action and passes the instruction corresponding to this action (instructing the mobile phone to automatically turn on the wireless reverse charging function) to the TWS earphones, and the TWS earphones send the instruction to the smartphone via Bluetooth.

[0180] For example, Figure 8 An example is shown in Figure 6 In the method shown, the schematic diagram of the processing flow of the earphone box, TWS earphones and smartphone is as follows: Figure 8 As shown, the earphone box is initially in a dormant state. When the user presses a button on the earphone box (for example, the first time, i.e., performing the second operation), the MCU in the earphone box is powered on and the TWS earphones are activated. When the user presses the button on the earphone box again (for example, the second time, i.e., performing the first operation), the MCU in the earphone box sends the instruction corresponding to the user operation (the second indication information) to the TWS earphones. The TWS earphones transmit the instruction (the first indication information) to the smartphone via the Bluetooth transmission channel. In response to the instruction, the smartphone automatically turns on the wireless reverse charging function.

[0181] State 2: The earphone box is powered off or in sleep mode, the TWS earphones are in the earphone box, and the TWS earphones are powered on or activated.

[0182] Figure 9 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state 2. Figure 9 As shown, the method 900 includes:

[0183] S901: The earphone box receives a second operation of a button on the earphone box by the user.

[0184] For example, the second operation may be that the user clicks or presses a button on the box one or more times.

[0185] S902: In response to the second operation, the earphone box is powered on or activated.

[0186] Since the TWS headset is in an activated state, the Bluetooth of the TWS headset will also enter an activated or working state. In this way, the TWS headset can establish a Bluetooth connection with the smartphone and establish a Bluetooth transmission channel.

[0187] That is to say, in the case of state 2, the user's second operation on the button on the earphone box is used to trigger: activation of the earphone box.

[0188] S903: The earphone box receives a first operation of a button on the earphone box by the user.

[0189] For example, the first operation can be that the user clicks or presses a button on the box once. Of course, in other implementations of the present application, the first operation can also be that the user clicks or presses this button multiple times.

[0190] S904, in response to the first operation, the earphone box sends a second indication message to the TWS earphone, where the second indication message is used to indicate: the TWS earphone instructs the electronic device to automatically turn on the wireless reverse charging function.

[0191] S905. In response to the second indication information, the TWS headset sends a first indication information to the smartphone, where the first indication information is used to instruct the smartphone to automatically turn on the wireless reverse charging function.

[0192] Correspondingly, the smartphone receives the first indication information.

[0193] S906: The smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0194] It can be seen that the difference between method 900 and method 600 is that after the earphone box is turned on or activated, the MCU in the earphone box does not need to activate the TWS earphones again.

[0195] For detailed descriptions of the various steps of method 900, reference may be made to the above descriptions of the corresponding steps in method 600, which will not be repeated here for the sake of brevity.

[0196] Through the above method, a button is set on the earphone box, and the user's second operation on the button can trigger the earphone box to change from a dormant state to an active state. Afterwards, the user's first operation on the button can trigger the earphone box to send a first indication message to the smartphone through the TWS earphones. After receiving the first indication message, the smartphone automatically turns on the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, avoiding the user manually turning on this function on the smartphone, and improving the user experience. In addition, through the first operation trigger: the earphone box sends the second indication message to the TWS earphones, and the TWS earphones sends the first indication message to the smartphone, it can avoid the earphone box continuously sending the second indication message and the TWS earphones continuously sending the first indication message, thereby reducing the power consumption of the earphone box and the TWS earphones, and increasing the usage time of the earphone box.

[0197] Optionally, as a possible implementation, in method 900, the earphone box may be in a closed (or powered off) state.

[0198] Optionally, in some possible implementations, if the earphone box is in a closed (or turned off) state, it means that the earphone box is in a powered-off or dormant state.

[0199] Optionally, as a possible implementation, if the earphone box is in a closed (or powered off) state, then in method 900, S901 may be replaced by: the user opening the earphone box. That is, the second operation may be the user opening or unpacking the earphone box, and the second operation is used to trigger: powering on or activating the earphone box.

[0200] Optionally, as a possible implementation method, in the above-mentioned state two, the user may also only perform the first operation or the second operation on the button on the earphone box. In this case, the first operation or the second operation of the user on the button on the earphone box is used to trigger: the earphone box is activated, the earphone box sends the second indication information to the TWS earphones, and the TWS earphones send the first indication information to the smartphone. After the first operation or the second operation is completed, the earphone box can be activated, the earphone box activates the TWS earphones, and the earphone box can send the second indication information to the TWS earphones. The second indication information is used to indicate: the TWS earphones instruct the electronic device to automatically turn on the wireless reverse charging function. In response to the second indication information, the TWS earphones can send the first indication information to the smartphone, and the smartphone can automatically turn on the wireless reverse charging function according to the first indication information. Optionally, the first operation or the second operation can be that the user clicks or presses the button on the earphone box once or multiple times.

[0201] State three: The earphone box is powered on or activated, the TWS earphones are in the earphone box, and the TWS earphones are powered off or in sleep mode.

[0202] Figure 10 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state three. Figure 10 As shown, the method 1000 includes:

[0203] S1001: The earphone box receives a first operation of a user on a button on the earphone box.

[0204] For example, the first operation may be that the user clicks or presses a button on the box one or more times.

[0205] S1002, in response to the first operation, the earphone box controls the TWS earphone to turn on or activate, and the earphone box sends a second indication information to the TWS earphone, where the second indication information is used to indicate: the TWS earphone instructs the electronic device to automatically turn on the wireless reverse charging function.

[0206] After the TWS headset enters the activated state, the Bluetooth of the TWS headset will also enter the activated or working state, so that the TWS headset can establish a Bluetooth connection with the smartphone and establish a Bluetooth transmission channel. In other words, in method 1000, "the TWS headset is activated or started" or "the first operation" can trigger "establishing a Bluetooth connection between the TWS headset and the smartphone."

[0207] That is to say, in state three, the user's first operation on the button on the earphone box is used to trigger: the earphone box activates the TWS earphones, and the earphone box sends second indication information to the TWS earphones.

[0208] Correspondingly, the TWS headset receives the second indication information.

[0209] S1003, in response to the second indication information, the TWS headset sends a first indication information to the smartphone, where the first indication information is used to instruct: the smartphone to automatically turn on the wireless reverse charging function.

[0210] Correspondingly, the smartphone receives the first indication information.

[0211] S1004: The smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0212] It can be seen that the difference between method 1000 and method 600 is that there is no need to activate the earphone box, and the user can only operate the button on the earphone box once (i.e., the first operation). This operation can be: click or press the button once or multiple times, which can trigger the earphone box to activate the TWS earphones, and the earphone box sends the second indication information to the TWS earphones, and the TWS earphones send the first indication information to the smartphone.

[0213] For detailed descriptions of other steps of method 1000, please refer to the above descriptions of corresponding steps in method 600. For the sake of brevity, they will not be repeated here.

[0214] Through the above method, a button is set on the earphone box. When the user presses or clicks the button, it can be triggered: the earphone box activates the TWS earphones, and the earphone box sends a first indication message to the smartphone through the TWS earphones. After receiving the first indication message, the smartphone automatically turns on the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, avoiding the user from manually turning on the function on the smartphone, and improving the user experience.

[0215] Status 4: The earphone box is powered on or activated, the TWS earphones are in the earphone box, and the TWS earphones are also powered on or activated.

[0216] Figure 11 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state four. Figure 11 As shown, the method 1100 includes:

[0217] S1101: The earphone box receives a first operation of a user on a button on the earphone box.

[0218] For example, the first operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0219] S1102, in response to the first operation, the earphone box sends a second indication message to the TWS earphone, where the second indication message is used to indicate: the TWS earphone instructs the electronic device to automatically turn on the wireless reverse charging function.

[0220] S1103, in response to the second indication information, the TWS headset sends a first indication information to the smartphone, where the first indication information is used to instruct: the smartphone to automatically turn on the wireless reverse charging function.

[0221] Correspondingly, the smartphone receives the first indication information.

[0222] S1104, the smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0223] It can be seen that the difference between method 1100 and method 600 is that the earphone box and the TWS earphones in the earphone box do not need to be activated. The user can only operate the button on the earphone box once (i.e., the first operation), which can be: clicking or pressing the button once or multiple times. This can trigger the earphone box to send the second indication information to the TWS earphones, and the TWS earphones to send the first indication information to the smartphone.

[0224] For detailed descriptions of other steps of method 1100, please refer to the above descriptions of corresponding steps in method 600. For the sake of brevity, they will not be repeated here.

[0225] Through the above method, a button is set on the earphone box. After the user presses or clicks the button, the earphone box can be triggered to send a first indication message to the smartphone through the TWS earphones. After receiving the first indication message, the smartphone automatically turns on the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, avoiding the user from manually turning on this function on the smartphone, and improving the user experience. In addition, through the first operation triggering: the earphone box sends the second indication message to the TWS earphones, and the TWS earphones send the first indication message to the smartphone, it can avoid the earphone box continuously sending the second indication message and the TWS earphones continuously sending the first indication message, thereby reducing the power consumption of the earphone box and the TWS earphones, and increasing the usage time of the earphone box.

[0226] In other possible implementations, the earphone box can also have Bluetooth functionality. For example, a Bluetooth chip can be set up in the earphone box, and the MCU in the earphone box can control the Bluetooth chip. In this case, the main functions of the earphone box include: storing TWS earphones, charging TWS earphones, and communicating with other devices (such as TWS earphones, smartphones, etc.) through Bluetooth. The earphone box can also be in the off (sleep) or on (active) state. These states are described below.

[0227] State 5: The earphone box has Bluetooth functionality and is powered off or in sleep mode. Optionally, the earphone box may contain a TWS earphone (i.e., the TWS earphone is in the earphone box), or the earphone box may not contain a TWS earphone (i.e., the TWS earphone is not in the earphone box).

[0228] Figure 12 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state five. Figure 12 As shown, the method 1200 includes:

[0229] S1201: The earphone box receives a second operation of a user on a button on the earphone box.

[0230] For example, the second operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0231] S1202: In response to the second operation, the earphone box is powered on or activated.

[0232] It is understood that when the earphone box is activated or started, the Bluetooth of the earphone box will also be activated or in operation, so that the earphone box can establish a Bluetooth connection with the smartphone and establish a Bluetooth transmission channel. In other words, in method 1200, "the earphone box is activated or started" or "the second operation" can trigger the establishment of a Bluetooth connection between the earphone box and the smartphone.

[0233] That is to say, in the case of state five, the user's first operation of the button on the earphone box is used to trigger: the earphone box is activated.

[0234] For the process of establishing a Bluetooth connection between the earphone box and the smartphone, please refer to the description of the Bluetooth connection between the TWS earphones and the smartphone in S602 of method 600. For the sake of brevity, it will not be repeated here.

[0235] S1203: The earphone box receives a first operation of a button on the earphone box by the user.

[0236] For example, the first operation may be that the user clicks or presses a button on the earphone box once. Of course, in other implementations of the present application, the first operation may also be that the user clicks or presses the button multiple times.

[0237] S1204: In response to the first operation, the earphone box sends a first instruction message to the smartphone, where the first instruction message is used to instruct the smartphone to automatically turn on the wireless reverse charging function.

[0238] Correspondingly, the smartphone receives the first indication information.

[0239] Exemplarily, the earphone box may send the indication information to the smartphone via a Bluetooth transmission channel between the earphone box and the smartphone.

[0240] S1205: The smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0241] It is understandable that the earphone box can send the first indication information to one or more second electronic devices that have been connected to it by Bluetooth (i.e., a Bluetooth transmission channel has been established). After receiving the first indication information, the one or more second electronic devices connected to the earphone box by Bluetooth automatically turn on the wireless reverse charging function. If multiple second electronic devices automatically turn on the wireless reverse charging function, the user can place the earphone box in the wireless charging coil area of ​​a second electronic device (such as a first smartphone) that needs reverse wireless charging according to their needs.

[0242] Optionally, for electronic devices that do not need reverse wireless charging for the headphone box, within a preset time period, if the electronic device detects that it has not performed reverse wireless charging for the headphone box, the electronic device can automatically turn off the wireless reverse charging function, thereby saving power and increasing the usage time of the electronic device.

[0243] Through the above method, a button is set on the earphone box, and the user's second operation on the button can trigger the earphone box to switch from a dormant state to an active state. After that, the user's first operation on the button can trigger the earphone box to send a signal (i.e., the first indication information) to the smartphone via Bluetooth. After receiving the signal, the smartphone automatically activates the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, avoiding the user's need to manually activate this function on the smartphone, and improving the user experience. In addition, by triggering the earphone box to send the first indication information to the smartphone through the first operation, the earphone box can be prevented from continuously sending the first indication information, thereby reducing the power consumption of the earphone box and increasing the usage time of the earphone box.

[0244] Optionally, as a possible implementation, in method 1200, the earphone box may be in a closed (or shut down) state.

[0245] Optionally, in some possible implementations, if the earphone box is in a closed (or turned off) state, it means that the earphone box is in a powered-off or dormant state.

[0246] Optionally, as another possible implementation, in method 1200, the earphone box may also be in an unboxed (or opened) state.

[0247] Optionally, as a possible implementation, if the earphone box is in a closed (or powered off) state, then in method 1200, S1201 may be replaced by: the user opening the earphone box. That is, the second operation may be the user opening or unpacking the earphone box, and the second operation is used to trigger: powering on or activating the earphone box.

[0248] Alternatively, as a possible implementation, in the aforementioned state five, the user may only perform the first operation or the second operation on the button on the earphone box. In this case, the first operation or the second operation on the button on the earphone box triggers: activation of the earphone box and sending of the first indication information to the smartphone. After the first operation or the second operation is completed, the earphone box can be activated, and the earphone box can send the first indication information to the smartphone.

[0249] State 6: The earphone box has Bluetooth functionality and is powered on or activated. Optionally, the earphone box may contain a TWS earphone (i.e., the TWS earphone is in the earphone box); or the earphone box may not contain a TWS earphone (i.e., the TWS earphone is not in the earphone box).

[0250] It can be understood that when the earphone box is in an activated state, the Bluetooth of the earphone box will also enter an activated or working state, so that the earphone box can establish a Bluetooth connection with the smartphone and establish a Bluetooth transmission channel.

[0251] Figure 13 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state six. Figure 13 As shown, the method 1300 includes:

[0252] S1301: The earphone box receives a first operation of a user on a button on the earphone box.

[0253] For example, the first operation may be that the user clicks or presses a button on the earphone box once or multiple times (for example, twice).

[0254] S1302: In response to the first operation, the earphone box sends a first instruction message to the smartphone, where the first instruction message is used to instruct the smartphone to automatically turn on the wireless reverse charging function.

[0255] Correspondingly, the smartphone receives the first indication information.

[0256] S1303: The smartphone automatically turns on the wireless reverse charging function according to the first instruction information.

[0257] It can be seen that the difference between method 1300 and method 1200 is that there is no need to activate the earphone box.

[0258] For detailed descriptions of each step of method 1300, please refer to the above descriptions of the corresponding steps in method 1200. For the sake of brevity, they will not be repeated here.

[0259] Through the above method, a button is provided on the earphone box, and a user's first operation on the button can trigger the earphone box to send a first instruction message to the smartphone via Bluetooth. After receiving the first instruction message, the smartphone automatically activates the wireless reverse charging function, thereby enabling the smartphone to charge the earphone box, eliminating the need for the user to manually activate this function on the smartphone, and improving the user experience. Furthermore, triggering the earphone box to send the first instruction message through the first operation can prevent the earphone box from continuously sending the first instruction message, thereby reducing the power consumption of the earphone box and increasing the usage time of the earphone box.

[0260] Alternatively, as a possible implementation, if the earphone box is in a closed (or powered off) state, then in method 1300, S1301 may be replaced by: the user opening the earphone box. That is, the first operation may be the user opening or unpacking the earphone box, and the first operation is used to trigger: the earphone box sending the first indication information to the smartphone.

[0261] It should be understood that in the examples shown in states 1 to 6 above, the earphone box or TWS earphones sends the first indication information in unicast form, that is, the first indication information is directional. For example, the earphone box or TWS earphones uses the Bluetooth connection established between the earphone box and the smartphone to send the first indication information to the smartphone, and the first indication information is used to instruct the smartphone to automatically turn on the wireless reverse charging function.

[0262] Optionally, in other implementations of the present application, the earphone box or TWS earphones may also send the first indication information in the form of broadcast, that is, the first indication information is not directional. For example, the earphone box or TWS earphones does not need to establish a communication connection with other electronic devices (including smart phones). In this case, when the earphone box or TWS earphones sends the first indication information, it can be sent in Bluetooth broadcast mode. For example, the earphone box or TWS earphones broadcasts the first indication information via Bluetooth, and the first indication information is used to indicate: automatically turn on the wireless reverse charging function. One or more second electronic devices (for example, including smart phones) that receive or detect the first indication information can automatically turn on the wireless reverse charging function in response to the first indication information.

[0263] In other possible implementations, the earphone case may also be equipped with a magnet and near field communication (NFC) functionality. For example, an NFC chip may be installed in the earphone case, and the earphone case can use NFC to send NFC information to nearby devices. This NFC information indicates that the wireless reverse charging function should be automatically activated. Because the magnet in the earphone case generates a magnetic field, a magnetic sensor (or magnetic inductor) in the smartphone can detect the magnetic field or changes in the magnetic field generated by the magnet in the earphone case. For example, if the earphone case is far from the smartphone, the magnetic sensor in the smartphone may not detect the magnetic field generated by the magnet in the earphone case. However, if the earphone case is close to the smartphone, the magnetic sensor in the smartphone can detect the magnetic field generated by the magnet in the earphone case. For another example, as the distance between the earphone case and the smartphone changes, the magnetic sensor in the smartphone can detect changes in the magnetic field generated by the magnet in the earphone case. Furthermore, as the distance between the earphone case and the smartphone decreases, the magnetic sensor in the smartphone detects that the magnetic field generated by the magnet in the earphone case will become stronger or stronger. Optionally, the earphone case may be in a powered-off (sleep) or powered-on (active) state. These states are described below.

[0264] Alternatively, as a possible implementation, the NFC chip or component in the headset box may not require the headset box to provide power. That is, regardless of whether the headset box is powered off or active, the NFC chip or component in the headset box can continuously send NFC information, which is used to instruct: automatically turn on the wireless reverse charging function. For example, the NFC in the headset box may include active NFC and passive NFC, etc., which are not limited in this embodiment of the present application.

[0265] Status 7: The earphone box has NFC functionality and is equipped with magnets. Optionally, the earphone box can contain TWS earphones (i.e., the TWS earphones are in the earphone box), or the earphone box can also not contain TWS earphones (i.e., the TWS earphones are not in the earphone box).

[0266] Figure 14 The figure shows a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in the case of state seven. Figure 14 As shown, the method 1400 includes:

[0267] S1401: The earphone box sends NFC information, which is used to instruct: automatically turn on the wireless reverse charging function.

[0268] S1402: The smartphone detects the NFC information sent by the earphone box and the magnetic field generated by the magnet of the earphone box.

[0269] S1403, when the smartphone detects the NFC information sent by the earphone box and the magnetic field generated by the magnet of the earphone box, the wireless reverse charging function is automatically turned on.

[0270] Optionally, the NFC information in S1401 may also be referred to as first indication information, and the first indication information is used to indicate: automatically turning on the wireless reverse charging function.

[0271] For example, as a possible implementation method, when the earphone box is relatively close to the smartphone, the smartphone can detect the magnetic field generated by the magnet of the earphone box, and when the smartphone detects the NFC information sent by the earphone box, the smartphone automatically turns on the wireless reverse charging function.

[0272] For another example, as another possible implementation method, when the earphone box is close to the smartphone and the distance between the earphone box and the smartphone changes, for example, when the user moves the earphone box closer and closer to the smartphone, the smartphone can detect the change in the magnetic field generated by the magnet in the earphone box, and when the smartphone detects the NFC information sent by the earphone box, the smartphone automatically turns on the wireless reverse charging function.

[0273] Through the above method, the earphone box has NFC functionality and is equipped with a magnet. The earphone box sends NFC information. When the smartphone detects the NFC information sent by the earphone box and the magnetic field generated by the earphone box's magnet, the wireless reverse charging function is automatically activated, allowing the smartphone to charge the earphone box, eliminating the need for the user to manually activate this function on the smartphone, thereby improving the user experience. Furthermore, the dual protection of NFC information and magnetic field can reduce the probability of smartphone misoperation and improve the accuracy and reliability of the smartphone's automatic activation of the wireless reverse charging function.

[0274] Alternatively, as another possible implementation, if the NFC chip or component in the headset box requires power from the headset box, that is, the MCU in the headset box can control the NFC chip. In this case, the headset box needs to be in an activated state before the NFC chip can be activated, and the NFC chip can only send NFC information after it is activated. For example, in the case described in state eight:

[0275] State 8: The earphone box has NFC functionality and is equipped with a magnet, and is powered off or in sleep mode. Optionally, a button may be provided on the earphone box.

[0276] Optionally, the earphone box may contain a TWS earphone (ie, the TWS earphone is in the earphone box), or the earphone box may not contain a TWS earphone (ie, the TWS earphone is not in the earphone box).

[0277] Figure 15 FIG. 1 is a schematic flow chart of a method for wireless reverse charging of an electronic device provided by the present application in state eight. Figure 15 As shown, the method 1500 includes:

[0278] S1501: The earphone box receives a first operation of a user on a button on the earphone box.

[0279] For example, the first operation may be that the user clicks or presses a button on the earphone box once or multiple times.

[0280] S1502: In response to a first operation on a button on the earphone box, the earphone box is powered on or activated, and the earphone box sends NFC information, where the NFC information is used to instruct: automatically turn on the wireless reverse charging function.

[0281] When the earphone box is in an activated state, the NFC function in the earphone box is enabled, that is, the MCU in the earphone box controls the NFC chip to send NFC information, and the NFC information is used to indicate: automatically turn on the wireless reverse charging function.

[0282] Of course, when the earphone box is in an activated state, the earphone box does not need to continuously send NFC information. In this case, the user's first operation of the button on the earphone box can trigger: the NFC chip in the earphone box sends NFC information.

[0283] That is, in state eight, the user's first operation of the button on the earphone box triggers the earphone box to be activated, and the NFC chip inside the earphone box to send NFC information. Alternatively, the user's first operation of the button on the earphone box triggers the NFC chip inside the earphone box to send NFC information.

[0284] Optionally, the NFC information in S1502 may also be referred to as first indication information, and the first indication information is used to indicate: automatically turning on the wireless reverse charging function.

[0285] S1503, when the smartphone detects the NFC information sent by the earphone box and the magnetic field generated by the magnet of the earphone box, the wireless reverse charging function is automatically turned on.

[0286] Through the above method, the earphone box has NFC function and is provided with a magnet. A button is set on the earphone box, and the user can trigger the first operation of the button: the earphone box changes from a dormant state to an active state, and the earphone box sends NFC information. When the smartphone detects the NFC information sent by the earphone box and the magnetic field generated by the magnet of the earphone box, the wireless reverse charging function is automatically turned on, so that the smartphone can charge the earphone box, avoiding the user from manually turning on the function on the smartphone, thereby improving the user experience. In addition, through the dual protection of NFC information and magnetic field, the probability of misoperation of the smartphone can be reduced, and the accuracy and reliability of the automatic activation of the wireless reverse charging function of the smartphone can be improved. In addition, by triggering the earphone box to send NFC information through the first operation, the earphone box can be prevented from continuously sending NFC information, reducing the power consumption of the earphone box and increasing the usage time of the earphone box.

[0287] Optionally, as a possible implementation method, if the earphone box is in a closed (or powered off) state, in method 1500, S1501 can be replaced by: the user opens the earphone box, that is, the first operation can be the operation of the user opening the earphone box or opening the box, and the first operation is used to trigger: the earphone box is turned on or activated, and the NFC chip in the earphone box sends NFC information; or, the first operation is used to trigger: the NFC chip in the earphone box sends NFC information.

[0288] Optionally, in method 1400 and method 1500, NFC information may also be replaced by Bluetooth information.

[0289] Of course, in the above-mentioned method 1400 and method 1500, if the earphone box does not have the NFC function, or in other words, the earphone box does not have the function of sending the first indication information to the smartphone, in this case, the earphone box can also send the first indication information to the smartphone through the TWS earphones. For example, the earphone box can send a second indication information to the TWS earphones, and the second indication information is used to indicate: the TWS earphones instruct the electronic device to automatically turn on the wireless reverse charging function. The TWS earphones respond to the second indication information and send the first indication information. The first indication information is used to indicate: automatically turn on the wireless reverse charging function.
