Description

Technical Field

[0001] This application relates to the field of charging case technology, and in particular to a wireless earphone charging method, device, system, chip, and electronic device. Background Technology

[0002] Currently, when wireless earbuds are inserted into the charging case, the charging case detects the insertion and provides power to the charging circuit of the wireless earbuds through a boost circuit, thereby charging the battery of the wireless earbuds.

[0003] When wireless earphone batteries are charging, the current in their charging circuit may not be the same as the current value when the charging case's boost circuit is most efficient. This will reduce the charging efficiency of the charging case and reduce the number of times the charging case powers the wireless earphone batteries.

[0004] Therefore, how to improve the charging efficiency of the charging case to increase the number of times the charging case can supply power has become an urgent problem to be solved. Summary of the Invention

[0005] Based on the above situation, the main purpose of this application is to provide a wireless earphone charging method, device, system, chip and electronic device to improve the charging efficiency of the charging case and increase the number of times the charging case can be powered.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A wireless earphone charging method, applied to a charging case, includes the following steps: Step S100: In response to detecting that the wireless earphone has entered the charging case, reading the load current IOP value corresponding to the highest efficiency value of the boost circuit of the charging case; Step S300: Determining charging information based on the IOP value and sending the charging information to the wireless earphone, so that the wireless earphone configures its charging circuit according to the charging information, so that the charging circuit operates at a target current value; Step S500: Providing power to the configured charging circuit of the wireless earphone through the boost circuit to charge the wireless earphone.

[0008] In one optional approach, step S300 specifically includes: converting the IOP value into a binary IOP value; sending the binary IOP value as charging information to the wireless earphone, so that the wireless earphone configures its charging circuit according to the charging information; the charging circuit is configured to operate at the IOP value; or the wireless earphone has multiple charging levels, and the target current value corresponding to the charging circuit under different charging levels is different, and the difference between the target current corresponding to the charging level configured for the charging circuit and the IOP value is the smallest.

[0009] In one optional approach, step S300 specifically includes: determining the charging level information of the wireless earphone based on the IOP value, wherein the charging level information represents the target current value corresponding to the operation of the charging circuit; and sending the charging level information as charging information to the wireless earphone so that the wireless earphone configures the charging circuit according to the charging level information.

[0010] In one alternative approach, determining the charging level information of the wireless earphones based on the IOP value includes: determining the charging level information corresponding to the current value with the smallest difference from the IOP value among multiple current values ​​corresponding to multiple charging level information as the charging level information to be sent to the wireless earphones.

[0011] In one alternative approach, the charging level information corresponding to the wireless earbuds is pre-stored in the charging case; or, before step S300, the charging case obtains the charging level information corresponding to the wireless earbuds.

[0012] In this embodiment, the charging case reads its IOP value and sends the corresponding charging information to the wireless earphone. After receiving the charging information, the wireless earphone configures its charging circuit according to the received information, so that the charging circuit operates at the target current value. The charging case provides power to the wireless earphone's charging circuit through a boost circuit. The wireless earphone stores the power obtained from the charging case into its battery according to the configured charging circuit. During the charging process described above, the current value in the load circuit of the charging case (i.e., the wireless earphone's charging circuit) is the target current value set according to the charging information. The charging information is determined based on the IOP value, which corresponds to the load current corresponding to the highest efficiency value of the boost circuit of the charging case. Therefore, setting the wireless earphone's charging circuit to operate at the target current value, i.e., setting the load circuit of the charging case's boost circuit to operate at the target current value, can make the charging case's boost circuit maintain a high charging efficiency, thereby increasing the number of discharge cycles of the charging case's battery.

[0042] The present application is described below based on embodiments, but the present application is not limited to these embodiments. In the following detailed description of the present application, some specific details are described in detail, but well-known methods, processes, flows, and elements are not described in detail in order to avoid obscuring the substance of the present application.

[0043] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0044] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0045] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0046] Currently, when traditional wireless earbuds are inserted into the charging case, the charging case detects the insertion and activates the boost circuit (i.e., the charging case controls the working state of the boost circuit). The wireless earbuds then activate the charging circuit, thereby using the charging case to charge the earbuds' batteries.

[0047] The drawback of the above method is that after the wireless earphones enable the charging circuit, the charging current of the wireless earphone battery depends entirely on the user configuration. That is, the user can change the operating parameters of the wireless earphones' charging circuit through relevant operations or settings, thereby adjusting the charging current.

[0048] The efficiency of the boost circuit in the charging case varies with the load current. The efficiency of the boost circuit increases as the load current increases. When the load current increases to a certain value (denoted as "IOP"), the efficiency no longer increases. When the load current is greater than the IOP value, the efficiency gradually decreases. Figure 1 This is a schematic diagram illustrating the variation of the efficiency of the charging case boost circuit with load current in an embodiment of this application, as shown below. Figure 1As shown, when the load current of the charging case's boost circuit is less than 130mA, the charging efficiency of the boost circuit increases with the increase of the load current; when the load current is equal to 130mA (IOP), the charging efficiency of the boost circuit reaches its maximum efficiency of 89.9%; when the load current of the charging case's boost circuit is greater than 130mA, the charging efficiency of the boost circuit decreases with the increase of the load current. The charging current of the wireless earbuds is different from the current value corresponding to the highest efficiency of the charging case's boost circuit, causing the charging case's boost circuit to not operate in its most efficient state, thus reducing the number of times the charging case charges the wireless earbuds' battery.

[0049] Based on this, the inventors of this application discovered that the charging case can send the charging information corresponding to the current value (i.e., IOP value) of the charging circuit when the charging case boost circuit is at its highest efficiency to the wireless earphones, so that the wireless earphones can configure the charging circuit according to the charging information, thereby improving the efficiency of the charging case boost circuit, keeping the charging case boost circuit in a high-efficiency working state, and increasing the number of discharges when the charging case charges the wireless earphones.

[0050] This application applies to wireless earbuds, and particularly to charging true wireless earbuds. This application can be used for charging a single earbud in a pair when placed in the charging case, or for charging both earbuds in a pair when placed in the charging case simultaneously.

[0051] Figure 2 Please refer to the schematic diagram of the frame of the wireless earphones and charging case provided in the embodiments of this application. Figure 2 The charging case's circuitry includes a General Purpose Input / Output (GPIO) interface, control circuitry, charging circuitry, boost circuitry, and a battery. The wireless earbuds' circuitry also includes a GPIO interface, control circuitry, charging circuitry, and a battery. After the wireless earbuds are placed in the charging case, specifically after the earbuds enter the case and their electrical contacts make contact with the charging case's electrical contacts, the boost circuitry within the charging case begins operating, converting the low voltage of the charging case's battery to a high voltage to meet the charging needs of the earbuds' battery. The charging case's charging circuitry, using a constant current / constant voltage control algorithm, converts the high voltage output from the boost circuitry into a voltage suitable for charging the earbuds' battery and controls the current magnitude to ensure safe and efficient battery charging. The control circuitry within the wireless earbuds detects the charging signal from the charging case and charges the battery within the earbuds according to the charging voltage and current of the charging case, enabling the earbuds' battery to store electrical energy. Both the charging case and the control circuitry within the wireless earbuds monitor the charging process in real time to ensure normal charging status. When the control circuits in the charging case and the wireless earbuds detect that the wireless earbuds battery is fully charged or has reached the preset charging level, the charging process is terminated.

[0052] Figure 3 This is a flowchart illustrating a wireless earphone charging method provided in an embodiment of this application. The method is executed by a wireless earphone charging device, which can be a charging case or a control unit within the charging case (which can be the control circuit described above or a separate control chip). Please refer to... Figure 3 The method includes the following steps:

[0053] Step S100: In response to detecting that the wireless earbuds have entered the charging case, read the load current IOP value corresponding to the highest efficiency value of the boost circuit of the charging case.

[0054] When the wireless earbuds are inside the charging case, they may be in one of two states: a charging state, in which the wireless earbuds draw a relatively large current from the charging case, typically above the mA level; and a fully charged state, in which the wireless earbuds are not actually charging, but at least some of their circuitry (e.g., control circuitry) is active and draws current from the charging case. In this case, the current drawn (or consumed) by the wireless earbuds is relatively small, typically below the mA level, and may even be in the μA level. In this embodiment, detecting that the wireless earbuds have entered the charging case, i.e., detecting that the wireless earbuds are in the case and are charging, can be confirmed by detecting that the wireless earbuds are fully placed in the charging case and electrically connected to the charging contacts of the charging case (e.g., pogo pin contact). Furthermore, the charging case can be controlled by a built-in charging controller (e.g., Figure 2 The control circuit shown determines whether the earbuds are charging and charges them accordingly. The charging controller detects the current in the charging case; when the current is high (usually above mA), it indicates that the earbuds are charging. When the earbuds are charging, the charging controller controls the charging circuit to provide appropriate charging current and voltage to ensure a safe and efficient charging process. When the earbuds are fully charged, the charging controller detects that the charging current has decreased to a certain level (e.g., below μA) and cuts off the charging circuit to prevent overcharging. In addition, the charging case can also detect that the wireless earbuds are in the case and charging through communication with the earbuds.

[0055] When the charging case detects that the wireless earbuds are in the charging case and charging, it reads the IOP value stored there. The IOP value is the load current value corresponding to the highest efficiency of the boost circuit. That is, when the load current increases to the IOP value, the charging efficiency of the boost circuit no longer increases accordingly, but rather gradually decreases with increasing load current. Specifically, Figure 1 The 130mA in (130mA 89.9%) is... Figure 1The IOP value corresponds to the charging case. The magnitude of the IOP value is determined by the circuitry of the charging case. Therefore, the IOP value of a certain charging case is also stored in that charging case. When the IOP value is needed, the charging case can directly read its IOP value from its own memory.

[0056] Step S300: Determine the charging information based on the IOP value and send the charging information to the wireless earphone so that the wireless earphone can configure its charging circuit according to the charging information, so that the charging circuit operates at the target current value.

[0057] The IOP value is the load current value corresponding to the highest efficiency of the boost circuit of the charging case. The charging information determined by the IOP value can be the IOP value itself, the charging signal information of the charging case corresponding to the IOP value, or the load voltage value information corresponding to the highest efficiency of the boost circuit of the charging case, etc.

[0058] As one embodiment, the charging circuit can be configured in ways including but not limited to adjusting the resistance and / or inductance values ​​of the charging circuit.

[0059] Preferably, the charging case can send charging information to the wireless earbuds via a built-in communication module. Furthermore, the communication module can send the charging information to the wireless earbuds in the form of data packets via wireless communication technologies such as Bluetooth and Wi-Fi.

[0060] The configuration of the charging circuit for wireless earbuds includes setting charging control parameters. These parameters, such as charging current and voltage, are set based on charging information and the earbuds' charging needs. These parameters affect charging speed and efficiency and need to be adjusted according to actual conditions. Furthermore, after receiving charging information from the charging case, the control circuit within the earbuds monitors the charging process in real time. It needs to ensure that the charging circuit operates at the target current value during charging. Alternatively, after the earbuds' battery has charged to the preset level at the target current value, the earbuds can be further configured to optimize the charging circuit performance, such as reducing charging noise. The target current value is the current value that the earbuds can configure to match the charging information.

[0061] Step S500: Power is supplied to the wireless earphone's configured charging circuit via a boost circuit to charge the wireless earphone.

[0062] like Figure 2As shown, the boost circuit inside the charging case converts the low voltage of the charging case battery into a high voltage and outputs it to the wireless earbuds to provide the power required for charging the earbuds' batteries. The charging circuit inside the wireless earbuds stores the power into the earbuds' batteries to complete the charging process. When the control circuits inside the charging case and the wireless earbuds detect that the earbuds' batteries are fully charged or have reached a preset charge level, they control the charging process to end.

[0063] In this embodiment, the charging case reads its IOP value and sends the corresponding charging information to the wireless earphone. After receiving the charging information, the wireless earphone configures its charging circuit according to the received information, so that the charging circuit operates at the target current value. The charging case provides power to the wireless earphone's charging circuit through a boost circuit. The wireless earphone stores the power obtained from the charging case into its battery according to the configured charging circuit. During the charging process described above, the current value in the load circuit of the charging case (i.e., the wireless earphone's charging circuit) is the target current value set according to the charging information. The charging information is determined based on the IOP value, which corresponds to the load current corresponding to the highest efficiency value of the boost circuit of the charging case. Therefore, setting the wireless earphone's charging circuit to operate at the target current value, i.e., setting the load circuit of the charging case's boost circuit to operate at the target current value, can make the charging case's boost circuit maintain a high charging efficiency, thereby increasing the number of discharge cycles of the charging case's battery.

[0064] Specifically, firstly, the charging efficiency of the charging case's boost circuit is related to the load current; the charging efficiency is highest when the load current is IOP. For details, please refer to [link / reference needed]. Figure 1Secondly, the charging efficiency affects the number of times the charging case can be charged. The higher the charging efficiency of the boost circuit, the more times the battery in the charging case can be discharged. When the charging case detects the earphones entering, the battery in the charging case discharges. At this time, the input power of the charging case boost circuit = the voltage of the charging case battery * the output current of the charging case battery. The wireless earphones are charged using the current provided by the charging case. At this time, the output power of the charging case boost circuit = the voltage of the boost circuit * the load current (i.e., the charging current of the wireless earphones). The charging efficiency of the charging case boost circuit = output power / input power. The input power of the charging case boost circuit is fixed (the output of the charging case battery is fixed). The boost voltage provided by the charging case boost circuit is constant (e.g., 5V), while the load current depends on the settings of the wireless earphones. (For example, set to 15mA or 20mA). According to the formula Charging Efficiency = Output Power / Input Power, when the input power of the boost circuit is the same, that is, when the electrical energy released by the charging case is the same, the higher the charging efficiency of the boost circuit, the higher the output power of the boost circuit. The higher the output power, the higher the load current. The higher the load current, the more charge flows into the wireless earphone battery. Therefore, when the electrical energy output by the charging case battery is the same, the higher the charging efficiency of the boost circuit, the more electrical energy is stored by the wireless earphone battery. Therefore, when the charging amount of the charging case battery is constant, the higher the charging efficiency, the more times the charging case charges the wireless earphone.

[0065] Figure 4 This is a schematic diagram of the current change in the wireless earphone charging circuit provided in an embodiment of this application, as shown below. Figure 4 As shown in the embodiment of this application, when the charging case is charging the wireless earphones, the charging case detects that the wireless earphones have entered the charging case. Then, the boost circuit of the charging case receives the enable signal sent by the control circuit and converts the low voltage of the charging case battery to a high voltage. After the boost circuit of the charging case is enabled, the control circuit of the wireless earphones also sends an enable signal to its charging circuit. The wireless earphones adjust the current of the charging circuit of the wireless earphones according to the IOP value. At this time, the current value of the charging circuit of the wireless earphones is the IOP value (or a current value close to the IOP value). Figure 5 A schematic diagram of current change in a wireless earphone charging circuit provided in another embodiment of this application is shown below. Figure 5As shown, in a traditional charging case, when charging wireless earbuds, the charging case detects the earbuds entering the case. Then, the charging case's boost circuit receives an enable signal from the control circuit, converting the low voltage of the charging case battery to a high voltage. After the boost circuit is enabled, the wireless earbuds' control circuit also sends an enable signal to its charging circuit. The wireless earbuds adjust the current of their charging circuit according to the default charging level setting (e.g., set to the maximum current for fast charging). In this case, the current value of the wireless earbuds' charging circuit is not equal to the IOP value but is actually greater than it. Compared to the traditional charging case method, where the load current is set by the wireless earbuds according to the default charging level setting (e.g., set to the maximum current for fast charging), this embodiment sets the load circuit of the charging case's boost circuit to operate at the target current value. This allows the charging case's boost circuit to maintain higher charging efficiency, thereby increasing the number of discharge cycles of the charging case battery.

[0066] When the charging information is an IOP value, in one optional manner, step S300 specifically includes the following sub-steps:

[0067] S311 converts the IOP value to a binary IOP value.

[0068] S312 sends the binary IOP value as charging information to the wireless earphone so that the wireless earphone configures its charging circuit according to the charging information; the charging circuit is configured to work at the IOP value; or the wireless earphone has multiple charging levels, and the target current value corresponding to the charging circuit under different charging levels is different, and the difference between the target current corresponding to the charging level configured for the charging circuit and the IOP value is the smallest.

[0069] For example, when the IOP value is 20 (mA), 20 is first converted to binary to get 10100, and then 10100 is sent to the wireless earphone. After the wireless earphone receives 10100, it configures the charging circuit current to be 20mA.

[0070] The charging case converts the IOP value into binary before sending it to the wireless earbuds, which improves the transmission speed of charging information from the charging case to the wireless earbuds.

[0071] After receiving the IOP value sent by the charging case, the wireless earbuds select the charging level corresponding to the current value with the smallest difference from the IOP value from multiple charging levels of the charging circuit as the charging level that matches the IOP value; then the charging circuit of the wireless earbuds is configured according to the charging level that matches the IOP value so that the charging circuit works at the target current value.

[0072] In some cases, because wireless earbuds have charging levels, each corresponding to a fixed current value, if the IOP value is not equal to the current value corresponding to all charging levels of the wireless earbuds, the wireless earbuds cannot configure the target current value of the charging circuit to be the IOP value after receiving the IOP value. Therefore, the charging case can send the IOP value to the wireless earbuds, which then determine the charging level that matches the IOP value; alternatively, the charging case can determine the charging level that matches the IOP value and send the charging level information to the wireless earbuds. In one optional approach, step S300 specifically includes the following sub-steps:

[0073] S321, determine the charging level information of the wireless earphone based on the IOP value, wherein the charging level information represents the target current value corresponding to the operation of the charging circuit.

[0074] The charging level of wireless earphones refers to the current level of the charging circuit when the wireless earphone charging circuit is working. For example, the first charging level corresponds to 10mA, the second charging level corresponds to 12mA, and the third charging level corresponds to 14mA. This means that when the wireless earphone charging circuit is working, if the first charging level is selected, the current value in the wireless earphone charging circuit can be maintained at 10mA, the second charging level will be maintained at 12mA, and the third charging level will be maintained at 14mA. In some cases, the IOP value and the current value corresponding to the charging level of the wireless earphones are not equal. Therefore, the charging case can first determine the charging level information of the wireless earphones based on the IOP value. Preferably, the charging level closest to the IOP value is set as the charging level information of the wireless earphones. For example, if the IOP value is 11mA, then 10mA or 12mA can be used as the charging level information of the wireless earphones. In order to quickly determine the charging level information of the wireless earphones, the charging case can also take the charging level corresponding to the largest current value among the current values ​​smaller than the IOP value as the charging information and send it to the wireless earphones. For example, if the IOP value is 11mA, then 10mA can be used as the charging level information of the wireless earphones.

[0075] S322 sends the charging level information as charging information to the wireless earphones so that the wireless earphones can configure the charging circuit according to the charging level information.

[0076] The wireless earbuds configure the current of their charging circuit based on the charging level information sent by the charging case. For example, if the wireless earbuds receive a charging level information of 10mA, meaning the target current value is 10mA, then the wireless earbuds configure the charging circuit to maintain the current value of the charging circuit at 10mA during operation.

[0077] In order to make the target current value determined based on the charging information closer to the IOP value, in one optional embodiment, S321 includes:

[0078] S321a: Among the multiple current values ​​corresponding to multiple charging level information, the charging level information corresponding to the current value with the smallest difference from the IOP value is determined as the charging level information to be sent to the wireless earphone.

[0079] For example, in the charging levels of wireless earbuds, the first charging level corresponds to 10mA, the second charging level corresponds to 12mA, and the third charging level corresponds to 14mA, with an IOP value of 11.3. The charging case then sends the second charging level, corresponding to 12mA, which has the smallest difference from 11.3, to the wireless earbuds. Based on the received charging information corresponding to the second charging level, the wireless earbuds configure their charging circuit to the second charging level, so that the difference between the operating current value and the IOP value in the wireless earbuds' charging circuit is minimized.

[0080] Similarly, when the charging case sends the charging information as the IOP value rather than the charging level of the wireless earbuds, the wireless earbuds can select the charging level corresponding to the current value with the smallest difference from the IOP value from multiple charging levels in the charging circuit to configure the charging circuit of the wireless earbuds so that the charging circuit works at the target current value.

[0081] In one alternative approach, the charging level information corresponding to the wireless earbuds is pre-stored in the charging case.

[0082] If the charging case needs to convert IOP values ​​to the charging level information of the wireless earbuds, then the charging case needs to store multiple charging levels of the wireless earbuds.

[0083] In another alternative approach, prior to step S300, the wireless earphone charging method further includes:

[0084] S290: The charging case obtains the charging level information corresponding to the wireless earbuds.

[0085] There are multiple communication methods between wireless earbuds and the charging case. For example, the charging case can communicate with the wireless earbuds through a built-in communication module, which may include wireless communication modules such as Bluetooth and Wi-Fi. Alternatively, the charging case may have a GPIO interface, through which it establishes GPIO communication with the wireless earbuds.

[0086] After the wireless earbuds are inserted into the charging case, the charging case can achieve GPIO communication between the charging case and the wireless earbuds by electrically connecting to the charging contacts of the wireless earbuds (such as contact with the pogo pin).

[0087] GPIO is a hardware interface used to enable bidirectional communication in computers or other electronic devices. In communication between the charging case and the wireless earbuds, the GPIO interface is used to connect the charging case and the wireless earbuds so that data can be transferred between them.

[0088] In another alternative, the charging case establishes a Bluetooth Low Energy (BLE) connection with the wireless earbuds.

[0089] BLE is a short-range communication technology used for wireless data transmission between various electronic devices. Compared to traditional Bluetooth technology, BLE technology has advantages such as low power consumption, low cost, and short range, making it particularly suitable for the communication needs of low-power devices such as smart wearable devices and IoT devices.

[0090] During the process of establishing a BLE connection between the charging case and the wireless earbuds, the charging case and the wireless earbuds act as the master and slave devices respectively in the BLE communication, so that data can be transmitted between the charging case and the wireless earbuds.
