Description

Technical Field

[0001] This invention relates to the field of headphone technology, and more particularly to a method, apparatus, charging case, and computer-readable storage medium for pairing wireless headphones. Background Technology

[0002] With the rapid development and continuous innovation of TWS (True Wireless Stereo) earphones in recent years, TWS earphones have gradually replaced traditional Bluetooth earphones and become the choice of more and more users. To solve the problem of battery life in traditional Bluetooth earphones, TWS earphones are generally equipped with a charging case, which extends the battery life of TWS earphones.

[0003] Current TWS charging cases all have buttons for pairing and unpairing the earbuds with communication devices (such as mobile phones). The pairing process involves opening the earbud cover and pressing and holding the function button. Because of the button design, the charging case needs to have openings, which poses a risk to waterproofing, dustproofing, and electrostatic discharge protection. Furthermore, pairing is difficult when the charging case is covered with a protective case, and the hardware design for this button is costly. To overcome the shortcomings of the button design on the charging case, there is an urgent need for a technical solution that allows TWS earbuds to pair with communication devices without requiring buttons on the charging case. Summary of the Invention

[0004] The main objective of this invention is to provide a method, apparatus, charging case, and computer-readable storage medium for pairing wireless earphones, aiming to solve the technical problem of how to achieve pairing between TWS earphones and communication devices without requiring a button design on the charging case.

[0005] To achieve the above objectives, the present invention provides a method for pairing wireless earphones, wherein the method is applied to the charging case of the wireless earphones, and the method includes the following steps:

[0006] Determine the current distance between the device to be paired and the charging case;

[0007] If the current distance is less than or equal to the first preset distance, then determine the open / closed state of the charging case.

[0008] If the lid is in the open state, a pairing command is sent to the target earphone connected to the charging case so that the target earphone is paired with the device to be paired.

[0009] Optionally, before the step of determining the current distance between the device to be paired and the charging case, the method further includes:

[0010] Obtain multiple real-time distances between the device to be paired and the charging case;

[0011] Based on the multiple real-time distances, determine the corresponding distance change trend;

[0012] If the distance change trend is a decreasing trend, then the step of determining the current distance between the device to be paired and the charging box is performed.

[0013] Optionally, after the step of saying that the current distance is less than or equal to a first preset distance, the method further includes:

[0014] Determine the target distance interval corresponding to the current distance;

[0015] Determine the duration of distance maintenance corresponding to the target distance range;

[0016] If the distance is maintained for a duration greater than or equal to a preset duration, then the step of determining the open / closed state of the charging case is executed.

[0017] Optionally, prior to the step of sending a pairing command to the target earphone connected to the charging case, the method further includes:

[0018] If the lid is in the open state, then detect whether the target earphone is connected inside the charging case;

[0019] If a target earphone is connected inside the charging case, then the step of sending a pairing command to the target earphone connected to the charging case is executed;

[0020] If no target earphones are connected in the charging case, the user will be prompted to place the earphones in the charging case.

[0021] Optionally, after the step of determining the current distance between the device to be paired and the charging case, the method further includes:

[0022] If the current distance is less than or equal to the second preset distance, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed; wherein the second preset distance is less than the first preset distance.

[0023] Optionally, after the step of determining the open / closed state of the charging case, the method further includes:

[0024] If the cover is closed, then wireless earphone pairing information is sent to the device to be paired.

[0025] If a connection response command is received from the device to be paired based on the wireless earphone pairing information, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed.

[0026] Optionally, after the step of sending a pairing command to the target earphone connected to the charging case to pair the target earphone with the device to be paired, the method further includes:

[0027] Obtain the pairing result between the target earphone and the device to be paired;

[0028] If the pairing result is successful, the system will respond to the user's action of taking out the earphones and remind the user to close the charging case lid.

[0029] Furthermore, to achieve the above objectives, the present invention also provides a wireless earphone pairing device, the wireless earphone pairing device comprising:

[0030] The distance detection module is used to determine the current distance between the device to be paired and the charging case;

[0031] The lid detection module is used to determine the open / closed state of the charging box if the current distance is less than or equal to a first preset distance.

[0032] The pairing connection module is used to send a pairing command to the target earphone connected to the charging case if the opening / closing state is the open state, so that the target earphone is paired with the device to be paired.

[0033] In addition, to achieve the above objectives, the present invention also provides a charging case, including a processor, a storage unit, and a wireless earphone pairing program stored on the storage unit and executable by the processor, wherein when the wireless earphone pairing program is executed by the processor, the steps of the wireless earphone pairing method described above are implemented.

[0034] The present invention also provides a computer-readable storage medium storing a wireless earphone pairing program, wherein when the wireless earphone pairing program is executed by a processor, it implements the steps of the wireless earphone pairing method described above.

[0035] The wireless earphone pairing method in this invention detects and determines the current distance between the device to be paired and the charging case. When the current distance is less than a first preset distance, that is, when the device to be paired and the charging case are relatively close, it can be assumed that the user intends to pair the earphones in the charging case with the device to be paired. Furthermore, by judging the open / closed state of the charging case, when the open / closed state is that the charging case lid is open, it can be determined that the user intends to pair the earphones in the charging case with the device to be paired. Then, the charging case sends a pairing command to the earphones, thereby controlling the earphones to achieve pairing connection with the device to be paired. This invention eliminates the need for a conventional button design (pairing button) on the charging case, allowing pairing between the earphones and the communication device (the device to be paired) without the need for a pairing button. The user's pairing intention is determined simply by detecting the distance between the earphones and the communication device, automatically establishing a pairing connection. This reduces the hardware design cost of the charging case, resulting in a more seamless and integrated design. It also improves the charging case's waterproof, dustproof, and anti-static capabilities, as well as its intelligence. Furthermore, users no longer need to press and hold the pairing button to pair the earphones with the communication device, significantly enhancing the convenience and efficiency of earphone pairing.

[0048] Those skilled in the art will understand that Figure 1 The hardware structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0049] Continue to refer to Figure 1 , Figure 1 The storage unit 1005, which serves as a computer-readable storage medium, may include an operating system, a user interface module, a network communication module, and a program for pairing wireless earphones.

[0050] exist Figure 1 In this module, the network communication module is mainly used to connect to the server and communicate with it; while the processor 1001 can call the wireless headset pairing program stored in the storage unit 1005 and perform the following operations:

[0051] Determine the current distance between the device to be paired and the charging case;

[0052] If the current distance is less than or equal to the first preset distance, then determine the open / closed state of the charging case.

[0053] If the lid is in the open state, a pairing command is sent to the target earphone connected to the charging case so that the target earphone is paired with the device to be paired.

[0059] Determine the target distance interval corresponding to the current distance;

[0060] Determine the duration of distance maintenance corresponding to the target distance range;

[0061] If the distance is maintained for a duration greater than or equal to a preset duration, then the step of determining the open / closed state of the charging case is executed.

[0062] Furthermore, the processor 1001 can call the wireless earphone pairing program stored in the memory 1005, and also perform the following operations:

[0063] If the lid is in the open state, then detect whether the target earphone is connected inside the charging case;

[0064] If a target earphone is connected inside the charging case, then the step of sending a pairing command to the target earphone connected to the charging case is executed;

[0065] If no target earphones are connected in the charging case, the user will be prompted to place the earphones in the charging case.

[0066] Furthermore, the processor 1001 can call the wireless earphone pairing program stored in the memory 1005, and also perform the following operations:

[0067] If the current distance is less than or equal to the second preset distance, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed; wherein the second preset distance is less than the first preset distance.

[0068] Furthermore, the processor 1001 can call the wireless earphone pairing program stored in the memory 1005, and also perform the following operations:

[0069] If the cover is closed, then wireless earphone pairing information is sent to the device to be paired.

[0070] If a connection response command is received from the device to be paired based on the wireless earphone pairing information, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed.

[0071] Furthermore, the processor 1001 can call the wireless earphone pairing program stored in the memory 1005, and also perform the following operations:

[0072] Obtain the pairing result between the target earphone and the device to be paired;

[0073] If the pairing result is successful, the system will respond to the user's action of taking out the earphones and remind the user to close the charging case lid.

[0074] Based on the hardware structure of the controller described above, various embodiments of the wireless earphone pairing method of the present invention are proposed.

[0075] To facilitate understanding of the various embodiments of the present invention, the embodiments of the technical solution of the present invention are briefly summarized in terms of the overall solution:

[0076] This invention primarily utilizes a UWB (Ultra Wide Band) distance detection (positioning) module or other distance detection modules (such as infrared distance detection modules, ultrasonic distance detection modules, etc.) embedded in the charging case. The distance detection module acquires the distance between the charging case and the device to be paired. Based on this distance and its changes, it initially determines whether the user intends to pair the earphones. Furthermore, it confirms the user's pairing intention by observing the opening and closing of the charging case or other user actions. Once the user's pairing intention is accurately determined, the charging case controls the earphones within it to achieve pairing with the device to be paired. The entire pairing process is simple and quick, providing a user experience far superior to pairing via a pairing button.

[0077] This invention provides a method for pairing wireless earphones.

[0078] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a first embodiment of the wireless earphone pairing method of the present invention. In the first embodiment, the wireless earphone pairing method is applied to the charging case of the wireless earphones, and the method includes the following steps:

[0079] Step S10: Determine the current distance between the device to be paired and the charging case;

[0080] In this embodiment, the distance and position relationship between the charging case and other paired devices can be established by setting one or more distance detection modules, such as a UWB distance detection module, an ultrasonic distance detection module, an infrared distance detection module, and a Bluetooth distance detection module. When setting any of the above distance detection modules, the distance detection module can be placed at any position within the charging case. To maintain a more aesthetically pleasing and integrated appearance, it can be placed inside the charging case shell and not exposed on the visible outer or inner surfaces.

[0081] By replacing the traditional pairing button design with a distance detection module, it is possible to... Figure 6 The difference between the two can be seen in the text. Figure 6 The left side shows a conventional charging case with a pairing button, representing the existing design of charging cases. The right side shows a novel charging case that eliminates the button design, representing the improved design of this invention. It should be noted that the charging cases shown in the figures are merely examples and are not intended to limit the shape or appearance of charging cases.

[0082] Since the device to be paired also has a UWB equidistant detection module, the charging case can detect the current distance between the device and the charging case at a certain detection frequency based on the aforementioned UWB equidistant detection module. The device to be paired refers to a communication device that has not yet completed pairing with the earphones in the charging case. This can be any communication device with earphone pairing and other communication functions, such as a mobile phone, tablet, or laptop; there are no restrictions on this. For example, when a user intends to pair newly purchased earphones or a new mobile phone, they can place the charging case containing the phone or earphones in a location close to the other device. At this time, the charging case can detect the current position between the phone and the charging case.

[0083] In one embodiment, prior to step S10, the method further includes:

[0084] Step a: Obtain the identification information of the communication device, and determine whether the communication device is a device to be paired based on the identification information;

[0085] Step b: If it is a device to be paired, then execute step S10.

[0086] Step c: If the device is already paired, no further action is required.

[0087] In this embodiment, the identification information of the communication device includes, but is not limited to, device identification code, device Bluetooth address, etc. The charging box compares the obtained identification information with the paired identification information table stored in the charging box system. If the identification information exists in the paired identification information table, the communication device is determined to be a paired device, and no processing is required to prevent the communication device that has been paired with the earphone in the charging box from frequently and accidentally pairing. If the identification information does not exist in the paired identification information table or the identification information is empty (i.e., no identification information of the communication device is obtained), the communication device is determined to be a device to be paired, and then the step of determining the current distance between the device to be paired and the charging box is performed to pair the earphones of the device to be paired.

[0088] Please refer to Figure 3 In one embodiment, prior to step S10, the method further includes:

[0089] Step S100: Obtain multiple real-time distances between the device to be paired and the charging case;

[0090] Before determining the current distance between the device to be paired and the charging case, the charging case needs to detect multiple real-time distances between itself and the device to be paired within a preset detection period. That is, multiple real-time distances are acquired at a certain detection frequency within the preset detection period to analyze changes in the distance between the device to be paired and the charging case. For example, if the preset detection period is 1 second and the detection frequency is 3 times / second, then 3 real-time distances will be acquired within that detection period. It should be noted that the detection period and detection frequency can be set according to actual needs and are not limited here, but it is necessary to ensure that at least 2 real-time distances are acquired within the preset detection period.

[0091] Step S110: Determine the corresponding distance change trend based on the multiple real-time distances;

[0092] After acquiring multiple real-time distances, the system compares adjacent real-time distances acquired in chronological order to determine the distance trend between the charging case and the device to be paired. If, for any two adjacent real-time distances, the distance acquired later is smaller than the distance acquired later, it indicates a decreasing distance trend, meaning the charging case and the device to be paired are getting closer. For example, if three real-time distances are acquired in chronological order (15cm, 12cm, and 9cm), it can be seen that the distance between the charging case and the device to be paired is decreasing, indicating a decreasing distance trend.

[0093] If for any two adjacent real-time distances, the real-time distance acquired later is greater than the real-time distance acquired later, it indicates that the corresponding distance change trend is a distance extension trend, meaning the distance between the charging case and the device to be paired is increasing. For example, taking three real-time distances acquired in chronological order (8cm, 13cm, 17cm), we can see that the distance between the charging case and the device to be paired is increasing, i.e., a distance extension trend.

[0094] If there are more than three real-time distances, and if there are both instances where the real-time distance obtained later is less than that obtained later, and instances where the real-time distance obtained later is greater than that obtained later, then the distance change trend is neither a distance shortening trend nor a distance lengthening trend, and the user's behavioral intention is in a pending state. For example, if three real-time distances are obtained, in the order of their acquisition time, they are 10cm, 15cm, and 11cm respectively. It can be seen that the distance between the charging box and the device to be paired is neither a distance shortening trend nor a distance lengthening trend.

[0095] Step S120: If the distance change trend is a distance shortening trend, then perform the step of determining the current distance between the device to be paired and the charging box.

[0096] If the distance trend is a decreasing trend, that is, the user is placing the charging case and the device to be paired closer and closer, it can be reasonably and accurately determined that the user's behavioral intention is to pair the earphones in the charging case with the device to be paired. Then, the step of determining the current distance between the device to be paired and the charging case is executed to further determine the user's clear and true behavioral intention.

[0097] In one embodiment, if the distance change trend is neither a distance shortening trend nor a distance lengthening trend, or if it is neither a distance shortening trend nor a distance lengthening trend, no processing is required. This ensures accurate determination of the user's earphone pairing intention, prevents various possible accidental triggering of pairing operations, and avoids unnecessary interference to the user.

[0098] Step S20: If the current distance is less than or equal to the first preset distance, determine the open / closed state of the charging case.

[0099] The current distance is compared with a first preset distance in the system. If the current distance is less than or equal to the first preset distance, it indicates that the distance between the charging case and the device to be paired is relatively close. This allows for further determination of whether the user's behavior constitutes an intention to pair the earphones. Furthermore, the user's true and explicit behavioral intention can be identified by judging the open / closed state of the charging case. Specifically, a Hall IC (Hall Sensor) device can be built into the charging case to identify the open / closed state of the charging case. It should be noted that the first preset distance can be set according to actual needs, such as 10cm, and is not limited here.

[0100] Please refer to Figure 4 In one embodiment, after step S20, if the current distance is less than or equal to a first preset distance, the method further includes:

[0101] Step S200: Determine the target distance interval corresponding to the current distance;

[0102] In this embodiment, considering that it is difficult for the user to maintain a precise current distance while moving the charging case or the device to be paired, the current distance may not be constant due to hand tremors or attempts to pair at a closer distance. Therefore, after determining that the current distance is less than or equal to a first preset distance, a target distance interval can be determined based on the current distance. The method for determining the target distance interval can be as follows: taking the current distance as a reference, the minimum value of the target distance interval is 0 or any other value less than the current distance, and the maximum value is the sum of the current distance and the preset compensation distance, thereby forming the corresponding target distance interval. The preset compensation distance can be set according to actual needs, such as 2cm. The purpose of setting this compensation distance is mainly to prevent hand tremors from causing the distance between the charging case and the device to be paired to exceed the first preset distance, thus terminating the pairing. For example, if the current distance is 9cm and the first preset distance is 10cm, the target distance interval corresponding to the current distance can be [0, 11], [8, 11], [7, 11], etc.

[0103] Step S210: Determine the duration of distance maintenance corresponding to the target distance interval;

[0104] As long as the current distance between the device to be paired and the charging box is still within the target distance range corresponding to the original current distance, the distance maintenance time can be continuously counted, thereby further identifying the user's behavioral intentions.

[0105] Step S220: If the distance maintenance duration is greater than or equal to a preset duration, then the step of determining the open / closed state of the charging case is executed.

[0106] If the distance is maintained for a duration greater than or equal to a preset duration, it indicates that the user intends to pair the earphones. The user's true intention is then determined by judging the open / closed state of the charging case. The preset duration can be set as needed, such as 1 second or 2 seconds, and is not limited here.

[0107] This embodiment further tracks and confirms that the user's behavioral intent is likely to be the intent to pair the headphones, which further improves the recognition of the user's intent to pair the headphones, thereby accurately pairing the headphones with the device to be paired and preventing accidental pairing.

[0108] Step S30: If the opening / closing state is open, a pairing command is sent to the target earphone connected to the charging case so that the target earphone is paired with the device to be paired.

[0109] When the charging case is determined to be in the open state (i.e., the lid is open), the user's true intention is to pair the earphones. Simultaneously, if the lid is open, the target earphones within the charging case are activated, allowing a pairing command to be sent. The target earphones can be TWS earphones or other earphones connected to the charging case, and can be one or a pair. The charging case has a built-in pop-pin (communication connection terminal) for connecting to the target earphones. After sending the pairing command, the target earphones activate their broadcast mode and appear in the list of available devices for pairing. Upon user interaction, the pairing device receives the pairing information from the target earphones, completing the pairing connection. Furthermore, if the user wishes to cancel the pairing, they can do so through the pairing device itself.

[0110] Please refer to Figure 5 In one embodiment, prior to step S30, which involves sending a pairing command to the target earphone connected to the charging case, the method further includes:

[0111] Step S300: If the opening / closing state is open, then detect whether the target earphone is connected inside the charging case.

[0112] In this embodiment, if the lid is in the open state, that is, the charging case lid is open, it is possible to further detect whether there are target earphones connected inside the charging case, and also to determine the number of target earphones connected inside the charging case.

[0113] Step S310: If a target earphone is connected inside the charging case, then the step of sending a pairing command to the target earphone connected to the charging case is executed.

[0114] If there are target earphones connected to the charging case, the number of target earphones can be determined, and then pairing instructions can be sent to each target earphone connected to the charging case according to the number.

[0115] Step S320: If no target earphone is connected in the charging case, remind the user to place the earphone in the charging case.

[0116] If no target earphones are connected in the charging case, it can generally be determined that there are no earphones in the charging case. This can remind the user to place the earphones in the charging case, thus helping the user to successfully complete the earphone pairing. Another situation where no target earphones are connected in the charging case is that there is poor contact between the target earphones and the charging case. In this case, the user can be reminded to correctly restore the target earphones to their position in the charging case to further complete the earphone pairing.

[0117] The wireless earphone pairing method in this invention detects and determines the current distance between the device to be paired and the charging case. When the current distance is less than a first preset distance, that is, when the device to be paired and the charging case are relatively close, it can be assumed that the user intends to pair the earphones in the charging case with the device to be paired. Furthermore, by judging the open / closed state of the charging case, when the open / closed state is that the charging case lid is open, it can be determined that the user intends to pair the earphones in the charging case with the device to be paired. Then, the charging case sends a pairing command to the earphones, thereby controlling the earphones to achieve pairing connection with the device to be paired. This invention eliminates the need for a conventional button design (pairing button) on the charging case, allowing pairing between the earphones and communication devices without the need for a pairing button. The user's pairing intention is determined simply by detecting the distance between the earphones and the communication device, automatically establishing a pairing connection. This reduces the hardware design cost of the charging case, resulting in a more seamless and integrated design. It also improves the charging case's waterproof, dustproof, and anti-static capabilities, as well as its intelligence. Furthermore, users no longer need to press and hold the pairing button to pair the earphones with the communication device, significantly enhancing the convenience and efficiency of earphone pairing.

[0118] In one embodiment, after step S10, the method further includes:

[0119] If the current distance is less than or equal to the second preset distance, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed; wherein the second preset distance is less than the first preset distance.

[0120] In this embodiment, the second preset distance is less than the first preset distance. For example, if the first preset distance is 10cm, the corresponding second preset distance can be 8cm, 7cm, etc. In addition, the second preset distance can also be 0, that is, the charging box is in contact with the device to be paired.

[0121] If the current distance is less than or equal to a second preset distance, it indicates that the distance between the charging case and the device to be paired is very close, and the user's intention to pair the headphones can be recognized. Considering that many users often forget to open the charging case lid or are unaware that pairing headphones requires opening the lid, this system can automatically adjust the charging case lid to the open state, i.e., automatically open the lid, and execute the step of sending the pairing command to the target headphones connected to the charging case to achieve pairing connection between the target headphones and the device to be paired. Through this embodiment, the pairing needs of more users can be met to the greatest extent, avoiding the inability to pair headphones when users are unaware of or forget the pairing process, and providing greater convenience, choice, and intelligence for pairing connections between headphones and devices to be paired.

[0122] In one embodiment, after step S20, which determines the open / closed state of the charging case, the method further includes:

[0123] If the cover is closed, then wireless earphone pairing information is sent to the device to be paired.

[0124] In this embodiment, if the lid is closed, the target earphone is usually in a dormant state. Considering that some users may forget or not understand the pairing process, in order to further determine the user's true intention, the charging case can simulate the target earphone in the charging case sending wireless earphone pairing information to the device to be paired. Specifically, the earphone identifier or Bluetooth identifier of the target earphone can be obtained, and then the charging case can simulate the broadcast (wireless earphone pairing information) of the target earphone through the UWB module or other communication module using the earphone identifier and the Bluetooth identifier, so that the target earphone is displayed in the device list of the device to be paired.

[0125] If a connection response command is received from the device to be paired based on the wireless earphone pairing information, the opening / closing state of the charging case is adjusted to the open state, and the step of sending a pairing command to the target earphone connected to the charging case is executed.

[0126] If a user sees the target earphones displayed in the device list and performs a pairing operation, the corresponding charging case receives a connection response command from the device to be paired based on the wireless earphone pairing information. At this point, the user's earphone pairing intention can be clearly determined, and the charging case's open / closed state can be adjusted to the open state, that is, the case lid can be automatically opened (popped open), or the user can be prompted to open the case lid. After the case lid is opened and the target earphones are activated, the step of sending a pairing command to the target earphones connected to the charging case is executed, thereby realizing the pairing and connection between the target earphones and the device to be paired.

[0127] This embodiment can more accurately and reliably determine the user's headphone pairing intention. Even if the user forgets or is unclear about some headphone pairing procedures, it can provide the user with maximum headphone pairing convenience, thereby improving headphone pairing efficiency and enhancing the user experience.

[0128] In one embodiment, after step S30, the method further includes:

[0129] Obtain the pairing result between the target earphone and the device to be paired;

[0130] If the pairing result is successful, the system will respond to the user's action of taking out the earphones and remind the user to close the charging case lid.

[0131] In this embodiment, during the pairing process between the device to be paired and the target earphone in the charging case, the pairing result from the target earphone or the device to be paired can be obtained, i.e., the result of successful pairing or failed pairing.

[0132] If the target earbuds successfully pair with the device to be paired, upon receiving a disconnection command from the charging case, it can be determined that the user has removed the target earbuds. In response to the user's earbud removal operation, a timer begins. After a preset duration, the charging case lid can automatically close or remind the user to close the lid, preventing dust and other contaminants from entering the charging case and affecting future use, thus extending the lifespan of both the charging case and the earbuds. The preset duration can be set according to actual needs, for example, 2 seconds. That is, after the user removes the earbuds, if the charging case lid is still open after 2 seconds, it can automatically close the lid or remind the user to close it. The reminder can be given through the charging case's voice function or light function, or a reminder message can be sent to the device to be paired to remind the user to close the lid.

[0133] If pairing between the target earphone and the device to be paired fails, a pairing command can be resent to the target earphone connected to the charging case to ensure successful pairing.

[0155] Optionally, the pairing connection module A30 is further configured to:
