[0002] With the development of modern technology, wireless headphones have become widely used due to their ease of use, and their size is getting smaller and smaller. In order to achieve long battery life, wireless headphones need to be equipped with a matching charging case for charging.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0038] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, system, product, or apparatus that comprises a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, products, or apparatuses.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] In this embodiment, both the first and second wireless earbuds are wireless earbuds. After pairing, they function as a single wireless earbud pair. The wireless earbuds communicate with the charging case using the UART protocol, enabling half-duplex or full-duplex communication. The UART module includes two ports: TXD and RXD. The wireless earbuds and the charging case are connected via a Pogo pin (spring-loaded pin), which serves as the power supply contact point. Specifically, communication between the charging case and the wireless earbuds is initiated by the charging case, which establishes a data transmission link. Data transmission between the wireless earbuds and the charging case is achieved through this link. Communication between the first and second wireless earbuds is also initiated by the charging case, which establishes the data transmission link.

[0041] Optionally, the wireless headphones can be in-ear wireless headphones or ear-hook wireless headphones; this application embodiment does not limit the types.

[0042] Optionally, the charging box can be a wireless charging box or a wired charging box; this application embodiment does not limit the specific type of charging box.

[0043] Wireless earbuds can be stored, charged, and used for communication in the charging case. Once the wireless earbuds are placed in the charging case, the charging case charges the wireless earbuds through the power contact points until the wireless earbuds are fully charged. That is, by default, the wireless earbuds are in the charging state when they are placed in the charging case.

[0044] The charging case may include: a charging case shell and two charging cavities (a first charging cavity and a second charging cavity), the two charging cavities being sized and shaped to receive a pair of wireless earphones (a first wireless earphone and a second wireless earphone); one or more magnetic earphone shell components disposed within the charging cavities, the one or more magnetic earphone shell components being used to magnetically attract and magnetically fix the pair of wireless earphones to the two charging cavities respectively; the charging case also includes multiple power supply contacts for connecting the wireless earphones; the charging case may also include a charging cover, wherein the first charging cavity is sized and shaped to receive the first wireless earphone, and the second charging cavity is sized and shaped to receive the second wireless earphone.

[0045] In one possible implementation, the charging case may also include a sensing area, which may be located at the bottom of the two charging cavities respectively. At least one sensing sensor is provided in the sensing area for monitoring the wireless earphones. The sensing sensor may include a pressure sensor. When the wireless earphones are placed in the charging case, at least one pressure sensor can detect the change in its own pressure and thus detect the wireless earphones.

[0046] In one possible implementation, the charging case may further include a touch area, which may be located on the outer surface of the charging case housing. At least one touch sensor is disposed within the touch area to monitor touch operations. The touch sensor may include a capacitive sensor. When a user touches the touch area, at least one capacitive sensor can detect changes in its own capacitance to recognize the touch operation.

[0047] The wireless earphone may include an earphone shell, a rechargeable battery (e.g., a lithium battery) disposed within the earphone shell, multiple power supply contacts for connecting to a charging device, and a speaker assembly including a driver unit and a directional sound port. The driver unit includes a magnet, a voice coil, and a diaphragm, and is used to emit sound from the directional sound port. The multiple power supply contacts are disposed on the outer surface of the earphone shell, and the number of power supply contacts is the same as the number of power supply contacts in the charging case that is matched with the wireless earphone.

[0048] In one possible implementation, the wireless earphones may further include a touch area, which may be located on the outer surface of the earphone shell. At least one touch sensor is disposed within the touch area for detecting touch operations. The touch sensor may include a capacitive sensor. When a user touches the touch area, at least one capacitive sensor can detect a change in its own capacitance to recognize the touch operation.

[0049] In one possible implementation, the wireless earphone may also include an accelerometer and a three-axis gyroscope, which may be disposed inside the earphone housing. The accelerometer and the three-axis gyroscope are used to identify the actions of picking up and removing the wireless earphone.

[0050] In one possible implementation, the wireless earphones may also include at least one barometric pressure sensor, which can be disposed on the surface of the earphone shell to monitor the air pressure inside the ear after the wireless earphones are worn. The barometric pressure sensor can monitor the tightness of the wireless earphones. When the wireless earphones are detected to be loose, they can send a notification to an electronic device connected to the earphones to alert the user that the earphones are at risk of falling out.

[0051] The embodiments of this application will be described in detail below.

[0052] To better illustrate the embodiments of this application, the communication method between the charging case and the wireless earphones is first described. The wireless earphones and the charging case have various power supply contact point designs, mainly including: designs with two power supply contacts, designs with three power supply contacts, and designs with five power supply contacts. Among them, such as... Figure 1 As shown, in a two-power-point design, the two power-point contacts are a positive and a negative power-point. The negative power-point is used for grounding, and the positive power-point is used for charging. Therefore, to achieve communication between the charging case and the wireless earbuds, a single-wire communication method is required, meaning the charging case and the wireless earbuds share the positive power-point for both charging and communication. In a three-power-point design, one power-point is a negative power-point for grounding, one power-point is used for charging, and the other can be used for communication. A five-power-point design can cover all the functions of the above two designs and provides more functions for production line testing. Therefore, depending on the power-point design, the communication method between the charging case and the wireless earbuds can be: single-wire communication, two-wire communication, or multi-wire communication (three or more wires). However, most wireless earbud manufacturers currently use a two-power-point design for aesthetic and simpler earbud structures; therefore, communication between the charging case and the wireless earbuds via power-point contacts must be a single-wire communication method.

[0053] Please see Figure 2 , Figure 2 This is a schematic diagram of a single-wire communication structure between a charging case and wireless earphones according to an embodiment of this application, applied to, for example... Figure 1 The design of the two power supply contact points shown is as follows: Figure 2 As shown, the charging case, the first wireless earbuds, and the second wireless earbuds are interconnected via a voltage bus (VBUS), enabling communication between each other. The VBUS can be a charging cable that allows the charging case to charge the wireless earbuds through a positive power contact point.

[0054] The first wireless earphone can be a wireless earphone connected to the two charging power contacts of the charging case via two charging power contacts, and the second wireless earphone can be another wireless earphone connected to the two charging power contacts of the charging case via two charging power contacts.

[0055] Based on such Figure 2 The single-wire communication structure and UART communication protocol shown indicate that the charging case and wireless earphones can have two network topologies, network topology A (e.g., Figure 3A ) and network topology B (such as Figure 3B ).

[0056] like Figure 3A As shown, network topology A includes: a charging case, a first wireless earphone, and a second wireless earphone. The first and second wireless earphones are placed in the charging case. The first and second wireless earphones can communicate directly with the charging case, but they cannot communicate directly with each other. They need to use the charging case as a relay to forward data. The charging case can act as a master in the communication, actively initiating communication with the first and / or second wireless earphones, and initiating the process of switching from charging state to communication state. The first and second wireless earphones can act as slaves in the communication, synchronously switching from charging state to communication state and entering data receiving state.

[0057] like Figure 3BNetwork topology B includes: a charging case, a first wireless earphone, and a second wireless earphone. The first and second wireless earphones are placed in the charging case. The first and second wireless earphones can communicate directly with the charging case, and can also communicate directly with each other. When the charging case communicates with the first and / or second wireless earphones, the charging case acts as the master in the communication, and the first and / or second wireless earphones act as slaves. When the first and second wireless earphones communicate, the charging case and the second wireless earphones act as slaves, and the first wireless earphone acts as the master.

[0058] Please see Figure 4 , Figure 4 This application provides a schematic diagram of the structure of a single-wire communication system, which is applied to, for example... Figure 1 The charging case and the first wireless earbuds shown, as well as... Figure 3A Or such as Figure 3B The network topology shown indicates that the charging box can be as follows: Figure 3A Or such as Figure 3B The charging case shown allows the first wireless earbuds to be used as follows: Figure 3A Or such as Figure 3B The system shown includes a charging case and a first wireless earphone. The charging case is connected to the first wireless earphone and can charge and communicate with the first wireless earphone.

[0059] It should be noted that this embodiment demonstrates communication between the charging case and one wireless earphone (first wireless earphone) during charging. Communication between the charging case and another wireless earphone (second wireless earphone) during charging, as well as communication between the charging case and two wireless earphones during charging, can be implemented in the same or similar manner as the system provided in this embodiment. This embodiment does not impose any limitations on this.

[0060] Specifically, the charging case includes a controller, a switching circuit, a first power supply contact, a second power supply contact, and a battery. The first wireless earphone includes a controller, a switching circuit, a first power supply contact, a second power supply contact, a synchronization switching circuit, and a battery. To clearly distinguish the controller, switching circuit, first power supply contact, second power supply contact, and battery in the charging case from those in the first wireless earphone, in this embodiment, the controller, switching circuit, first power supply contact, second power supply contact, and battery in the charging case are respectively referred to as the first controller, first switching circuit, first power supply contact, second power supply contact, and first battery. The controller, switching circuit, first power supply contact, second power supply contact, and battery in the first wireless earphone are respectively referred to as the second controller, second switching circuit, third power supply contact, fourth power supply contact, and second battery. The second and fourth power supply contacts can be negative power supply contacts, and the first and third power supply contacts can be positive power supply contacts.

[0061] It should be noted that the first or second controller mentioned above can be a processor, a microcontroller unit (MCU), or a single-chip microcomputer.

[0062] Optionally, the I / O terminal of the first controller is connected to the control terminal of the first switching circuit, the first selection terminal of the first switching circuit is connected to the first battery, the second selection terminal of the first switching circuit is connected to the transceiver terminal of the UART module in the first controller, the common terminal of the first switching circuit is connected to one end of the first power supply contact, and the second power supply contact is grounded; the other end of the first power supply contact is connected to one end of the third power supply contact, the other end of the third power supply contact is connected to one end of the synchronous switching circuit and the common terminal of the second switching circuit, the other end of the synchronous switching circuit is connected to the control terminal of the second switching circuit, the first selection terminal of the second switching circuit is connected to the second battery, the second selection terminal of the second switching circuit is connected to the transceiver terminal of the UART module in the second controller, and the fourth power supply contact is grounded.

[0063] The synchronous switching circuit controls the switching of the switching circuit according to the input level; the RXD and TXD of the UART module in the first controller are shorted to form a transceiver terminal; the RXD and TXD of the UART module in the second controller are shorted to form a transceiver terminal.

[0064] Please see Figure 5 , Figure 5 This application provides a flowchart illustrating a single-wire communication method, applicable to, for example... Figure 1 The charging case and the first wireless earbuds shown, as well as... Figure 4The system shown can be such that the charging box can be Figure 3A The charging case shown allows the first wireless earbuds to be used as follows: Figure 3A The first wireless earphone shown, the single-wire communication method includes the following steps:

[0065] S501. When the charging case is charging the first wireless earphone through two power supply contact points, if it is detected that the charging case needs to communicate with the first wireless earphone, the charging case switches from the charging state to the communication state by sending a switching control signal to the first wireless earphone.

[0066] It should be noted that the two power supply contact points mentioned above can be the two power supply contact points provided in the charging case for connecting with the two charging power supply contact points of the first wireless earbuds to charge the first wireless earbuds, such as those provided with... Figure 1 The two circular power supply contacts of the first wireless earphone correspond to the two power supply contacts in the charging case.

[0067] The charging case may be equipped with a monitoring device to monitor the communication needs between the charging case and the first wireless earphone. When the charging case needs to communicate with the first wireless earphone, the monitoring device sends the monitoring results to the first controller, and the first controller can control the working status of the charging case according to the monitoring results.

[0068] Optionally, the charging case switches from a charging state to a communication state by sending a switching control signal to the first wireless earphone, including: the charging case controls the I / O terminal of the first controller to send a switching control signal to the first wireless earphone, controlling the first switching circuit to switch from a first selection terminal to a second selection terminal.

[0069] Specifically, the method by which the first switching circuit switches from the first selection terminal to the second selection terminal according to the switching control signal can be set by the designer according to the practical scenario and user needs. It can also be set according to the specific circuit structure in the charging box. For example, through software programming, when the first controller receives the monitoring result, the first controller I / O terminal outputs a high-level signal. When the control terminal of the first switching circuit receives the high-level signal, the first selection terminal of the first switching circuit is disconnected, and the second selection terminal is turned on, thereby realizing the switching of the first switching circuit from the first selection terminal to the second selection terminal. As long as it can be guaranteed that the first switching circuit can switch from the first selection terminal to the second selection terminal according to the switching control signal, this embodiment does not impose any restrictions on this.

[0070] The first switching circuit can be a single-pole double-throw control switch.

[0071] S502, the first wireless earphone switches from charging state to communication state.

[0072] Optionally, the first wireless earphone switching from the charging state to the communication state includes: controlling the second switching circuit to switch from the first selection terminal to the second selection terminal through a synchronous switching circuit.

[0073] The synchronous switching circuit controls the switching of the second switching circuit according to the switching control signal. The output signal of the synchronous switching circuit is synchronized with the switching control signal. That is, when the switching control signal switches the first switching circuit from the first selection terminal to the second selection terminal, the synchronous switching circuit also switches the second switching circuit from the first selection terminal to the second selection terminal.

[0074] Specifically, the implementation method of controlling the second switching circuit to switch from the first selection terminal to the second selection terminal through the synchronous switching circuit can be set by the designer according to the practical scenario and user needs, or it can be set according to the specific circuit structure in the charging box. For example, when the level of the input signal received by the synchronous switching circuit changes from low to high, the synchronous switching circuit outputs a high-level signal. When the control terminal of the second switching circuit receives the high-level signal, the first selection terminal of the second switching circuit is disconnected, and the second selection terminal is turned on, thereby realizing the switching of the second switching circuit from the first selection terminal to the second selection terminal. As long as it can be guaranteed that the second switching circuit can switch from the first selection terminal to the second selection terminal through the synchronous switching circuit, this embodiment does not impose any restrictions on this.

[0075] The second switching circuit can be a single-pole double-throw control switch.

[0076] S503, the charging box calls the UART module integrated in the first controller to send first data to the first wireless earphone.

[0077] In this configuration, the RXD and TXD terminals of the UART module in the first controller are shorted to form a transceiver terminal, and the charging case sends first data to the first wireless earphone through the transceiver terminal of the UART module in the first controller.

[0078] Optionally, the first data includes control instructions for controlling the first wireless headset and / or query instructions for obtaining information about the first wireless headset.

[0079] It is understood that the aforementioned first data can be data sent from the charging case to the first wireless earphone. The specific data type of the first data, i.e. the data type sent from the charging case to the first wireless earphone, can be set by the designer according to the practical scenario and user needs. For example, when the charging case needs to send control commands to the first wireless earphone, the first data can only include control commands; when the charging case also needs to send information query commands to the first wireless earphone, the first data can also include information query commands. This embodiment does not impose any restrictions on this.

[0080] The aforementioned control commands include, but are not limited to: pairing control commands, reset control commands, factory reset control commands, and OTA upgrade control commands. The aforementioned information query commands include, but are not limited to: version number query commands and battery level query commands.

[0081] S504. The first wireless earphone receives the first data and determines whether the first data is data sent by the first wireless earphone through the second controller. If it is, the first data is directly filtered or not processed. If it is not, the first data is analyzed through the second controller to obtain the analysis result, and the corresponding operation is performed according to the analysis result.

[0082] In this configuration, the RXD and TXD terminals of the UART module in the second controller are shorted to form a transceiver terminal, and the first wireless earphone receives the first data through the transceiver terminal of the UART module in the second controller.

[0083] Specifically, the second controller can decode the first data to obtain decoded data, and execute corresponding operations based on the instructions corresponding to the decoded data. The specific type of instruction can be set by the designer according to the practical scenario and user needs. For example, if the charging case needs to control the first wireless earbuds to restore factory settings during charging, the instruction can include a factory reset control instruction. The charging case can control the first wireless earbuds to restore factory settings by sending the factory reset control instruction. During charging, if the charging case also needs to obtain the battery level information of the first wireless earbuds, the instruction can also include a battery level query instruction, causing the first wireless earbuds to send their own battery level information to the charging case according to the battery level query instruction. This embodiment does not impose any restrictions as long as the first wireless earbuds can execute the corresponding operation according to the instruction corresponding to the first data.

[0084] S505, the first wireless earphone calls the UART module integrated in the second controller to send second data to the charging box.

[0085] The first wireless earphone sends second data to the charging case via the transceiver terminal of the UART module in the second controller.

[0086] Optionally, the second data includes status information for responding to control commands and / or query result information for responding to query commands.

[0087] S506. The charging box receives the second data and determines whether the second data is data sent by the charging box through the first controller. If it is, the second data is directly filtered or not processed. If it is not, the second data is analyzed through the first controller to obtain the analysis result, and the corresponding operation is performed according to the analysis result.

[0088] Specifically, the first controller can decode the second data to obtain decoded data, and execute corresponding operations based on the response instructions corresponding to the decoded data. The specific type of response instruction can be set by the designer according to the practical scenario and user needs. For example, if the first wireless earbuds need to respond to a factory reset control instruction sent by the charging case, the response instruction can include the factory reset status information of the first wireless earbuds. The charging case can then determine whether the first wireless earbuds have completed the factory reset operation based on the status information sent by the first wireless earbuds. If the first wireless earbuds also need to report their battery level information to the charging case, the response instruction can also include the battery level information of the first wireless earbuds. This embodiment does not impose any restrictions as long as the charging case can execute the corresponding operation based on the response instructions corresponding to the second data.

[0089] It should be noted that this embodiment demonstrates communication between the charging case and one wireless earphone (first wireless earphone) during charging. Communication between the charging case and another wireless earphone (second wireless earphone) during charging, as well as communication between the charging case and two wireless earphones during charging, can be achieved in the same or similar manner as the method provided in this embodiment. This embodiment does not impose any limitations on this.

[0090] As can be seen, the single-wire communication method and related products described in the embodiments of this application above achieve single-wire communication between the wireless earphones and the charging case by shorting the RXD and TXD of the UART in the controller into a single wire and adding a switching circuit. Applying this technology to wireless earphone products, especially to binaural wireless earphones with two power contact point charging interfaces and their matching charging cases, satisfies both the charging case's charging and communication functions for the wireless earphones, while maintaining a simple and aesthetically pleasing structure, reducing hardware resource consumption and software development difficulty, thereby lowering product costs.

[0091] Please see Figure 6 , Figure 6 A flowchart illustrating another single-wire communication method provided in this application embodiment, applied to, for example... Figure 1 The charging case, the first wireless earbuds, and the second wireless earbuds shown are as follows: Figure 4 The system shown can be such that the charging box can be Figure 3B The charging case shown allows the first wireless earbuds to be used as follows: Figure 3B The first wireless earphone shown, the second wireless earphone can be as follows: Figure 3B The second wireless earphone shown, the single-wire communication method includes the following steps:

[0092] S601. When the charging case is charging the first wireless earphone through two power supply contact points and charging the second wireless earphone through two other power supply contact points, if it is detected that the charging case needs to communicate with the first wireless earphone, the charging case switches the charging case connected to the first wireless earphone from the charging state to the communication state by sending a switching control signal to the first wireless earphone.

[0093] It should be noted that the two power supply contact points mentioned above can be the two power supply contact points provided in the charging case for connecting with the two charging power supply contact points of the first wireless earbuds to charge the first wireless earbuds, such as those provided with... Figure 1 The two circular power supply contacts of the first wireless earphone correspond to the two power supply contacts in the charging case; the other two power supply contacts can be two additional power supply contacts in the charging case used to connect with the two charging power supply contacts of the second wireless earphone to charge the second wireless earphone, such as...

[0094] It should be noted that the first and second wireless earbuds are identical in structure and function, and the single-wire communication system between the second wireless earbud and the charging case is the same as that between the first wireless earbud and the charging case. To clearly distinguish the controllers and switching circuits in the charging case, the first wireless earbud, and the second wireless earbud, this embodiment refers to the controller and switching circuit in the charging case as the first controller, the first switching circuit (for communicating with the first wireless earbud), and the third switching circuit (for communicating with the second wireless earbud), respectively; the controller and switching circuit in the first wireless earbud as the second controller and the second switching circuit, respectively; and the controller and switching circuit in the second wireless earbud as the third controller and the fourth switching circuit, respectively.

It can also be set according to the specific circuit structure in the charging box. For example, through software programming, when the first controller receives the monitoring result, the first controller I / O terminal outputs a high-level signal. When the control terminal of the first switching circuit receives the high-level signal, the first selection terminal of the first switching circuit is disconnected, and the second selection terminal is turned on, thereby realizing the switching of the first switching circuit from the first selection terminal to the second selection terminal. As long as it can be guaranteed that the first switching circuit can switch from the first selection terminal to the second selection terminal according to the switching control signal, this embodiment does not impose any restrictions on this.

For example, when the level of the input signal received by the first synchronous switching circuit changes from low to high, the first synchronous switching circuit outputs a high-level signal. When the control terminal of the second switching circuit receives the high-level signal, the first selection terminal of the second switching circuit is disconnected, and the second selection terminal is turned on, thereby realizing the switching of the second switching circuit from the first selection terminal to the second selection terminal. As long as it can be guaranteed that the second switching circuit can switch from the first selection terminal to the second selection terminal through the first synchronous switching circuit, this embodiment does not impose any restrictions on this.

When the control terminal of the third switching circuit receives the high-level signal, the first selection terminal of the third switching circuit is disconnected, and the second selection terminal is turned on, thereby realizing the switching of the third switching circuit from the first selection terminal to the second selection terminal. As long as it can be guaranteed that the third switching circuit can switch from the first selection terminal to the second selection terminal according to the switching control signal, this embodiment does not impose any restrictions on this.

[0129] It is understood that the aforementioned third data can be data sent from the first wireless earphone to the second wireless earphone. The specific data type of the third data, i.e., the data type sent from the first wireless earphone to the second wireless earphone, can be set by the designer according to the practical scenario and user needs.

The aforementioned information query commands include, but are not limited to: version number query commands and battery level query commands.

[0131] S610. The second wireless earphone receives the third data and determines whether the third data is data sent by the second wireless earphone through the third controller. If it is, the third data is directly filtered or not processed.

[0133] Specifically, the third controller can decode the third data to obtain decoded data, and execute corresponding operations based on the instructions corresponding to the decoded data. The specific type of instruction can be set by the designer according to the practical scenario and user needs. For example, if the first wireless earphone needs to control the second wireless earphone to restore factory settings while charging, the instruction can include a factory reset control instruction.

If it is, the fourth data is directly filtered or not processed. If it is not, the fourth data is analyzed by the second controller to obtain the analysis result, and the corresponding operation is performed according to the analysis result.

[0138] Specifically, the second controller can decode the fourth data to obtain decoded data, and execute corresponding operations based on the response instructions corresponding to the decoded data.
