Description

Technical Field

[0001] This invention relates to the field of wireless Bluetooth headsets, and more particularly to a charging case and a control method for wireless headsets. Background Technology

[0002] Currently, True Wireless Stereo (TWS) earbuds do not require a wired connection. The left and right earbuds connect via Bluetooth to form a stereo system, enhancing the user's sound quality experience and making them very popular. Because TWS earbuds are wire-free, and to extend their battery life and facilitate portability, they are usually accompanied by a charging case for storage. In addition, the charging case can also serve as a backup power source to charge the earbuds.

[0003] Existing charging cases require the wireless earbuds to be opened before they can be operated, such as pairing or checking the battery level, which is inconvenient for users. Summary of the Invention

[0004] The present invention provides a control method for a charging case and wireless earphones, which can solve the problem that existing wireless earphones can only be operated after the charging case is opened after being placed in it, thus simplifying the user's operation process.

[0005] To address the aforementioned technical problems, the first technical solution adopted by this invention is to provide a charging case for housing and charging wireless earphones, specifically including an input module, a processing module, and a first communication module. The input module detects user operation commands, the processing module converts the operation commands into control commands, and the first communication module forwards the control commands to the wireless earphones to control them to perform corresponding operations.

[0006] The operation commands include at least one or a combination of wake-up commands, pairing commands, and reset commands. The wake-up command is used to control the wireless earphones to switch from sleep mode to working mode, the pairing command is used to control the wireless earphones to perform Bluetooth pairing and connection, and the reset command is used to control the wireless earphones to restore factory settings.

[0007] The charging case further includes an indicator module for indicating the status of the charging case and / or the wireless earbuds.

[0008] The charging box further includes a power detection module and an indicator module. The power detection module is used to detect the power level of the charging box, and the operation instructions also include a power detection instruction. The power detection module is connected to the processing module, and the indicator module is used to indicate the power level of the charging box.

[0009] The first communication module further receives the battery level of the wireless earphone from the wireless earphone, and the indicator module further indicates the battery level of the wireless earphone.

[0010] The charging case further includes a positioning detection module, which is used to detect whether the wireless earphones are located inside the charging case, and an indication module is used to indicate the positioning status detected by the positioning detection module.

[0011] The operation instructions further include retrieval instructions and editing instructions. The retrieval instructions are used to control the wireless earphone to retrieve the list of playback files stored inside the wireless earphone, which is then displayed by the indicator module. The editing instructions are used to control the wireless earphone to perform corresponding editing operations on the playback files in the playback file list.

[0012] The first communication module further receives the pairing status of the wireless earphone from the wireless earphone, and the indication module further indicates the pairing status of the wireless earphone.

[0013] The charging case includes a box body and a cover, which are fitted together to form an accommodating space. The wireless earphones are housed within the accommodating space, and the box body or the cover is provided with a transparent window that allows the wireless earphones to be observed from the outside of the charging case.

[0014] To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is: to provide a control method for wireless earphones, the method comprising: detecting operation commands input by a user through a charging case; converting the operation commands into control commands; and forwarding the control commands to the wireless earphones to control the wireless earphones to perform corresponding operations. The beneficial effects of the present invention are:

[0015] Unlike existing technologies, this invention provides a control method for a charging case and wireless earphones. The charging case, by incorporating an input module, a processing module, and a first communication module, enables control of the wireless earphones without opening the case lid. The charging case can detect user input commands, convert them into control commands, and forward them to the wireless earphones for control. Therefore, the charging case can control the wireless earphones to perform corresponding operations and change their state based on user input commands. This invention solves the problem that existing wireless earphones require the case to be opened before operation, simplifying the user's workflow. Attached Figure Description

[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please see Figure 1 ,in, Figure 1This is a schematic diagram of a headphone assembly 10 provided in an embodiment of this application. In this embodiment, a headphone assembly 10 is provided, specifically including a charging case 12 and wireless headphones 11. The wireless headphones 11 can be or include any number of audio devices, such as true wireless stereo (TWS) headphones, bone conduction wireless headphones, in-ear wireless headphones, open-back wireless headphones, etc. The wireless headphones 11 can also be or include any wearable device designed to be worn on or around a user's head or ears, such as audio glasses, helmets, hats, and various other types of devices, such as hearing aids, AR devices, VR devices, head, shoulder, or body-worn acoustic devices, etc. These devices may specifically include or be connected to one or more acoustic drivers to generate sound, but may or may not be in contact with the user's ears. Specifically, the wireless headphones 11 may also include a speaker configured to generate sound in response to an audio signal sent to the speaker.

[0029] In this embodiment, the wireless earphone 11 can be housed in the charging case 12 for charging. The wireless earphone 11 includes a first earphone and a second earphone, which can be worn on the user's two ears respectively. The charging case 12 includes a body 121 and a cover 122, which cooperate to form a housing space 123 for housing the wireless earphone 11. The wireless earphone 11 is housed within the housing space 123. The body 121 may contain a battery, a charging management circuit, and charging contacts (not shown), so that after the wireless earphone 11 is placed in the housing, it can be electrically connected to the charging contacts and trigger the charging management circuit to charge the wireless earphone 11.

[0030] In one embodiment, the housing 121 or the cover 122 is provided with a transparent window that allows the wireless earphones 11 to be observed from the outside of the charging case 12, so that the user can directly observe whether the wireless earphones 11 are inside the charging case 12. When it is necessary to confirm whether the wireless earphones 11 are placed in the charging case 12, it is not necessary to open the cover 122 of the charging case 12; the user can directly observe whether the wireless earphones 11 are inside the charging case 12 from the outside. This avoids the situation where the user needs to open the cover 122 to check whether the wireless earphones 11 are inside the charging case 12, making the use of the charging case 12 more convenient. In other embodiments, part or all of the housing 121 and / or the cover 122 is made of transparent material, so that the presence of the wireless earphones 11 can be directly observed.

[0031] In this embodiment, the charging box 12 includes an input module 124, a processing module 125, and a first communication module 126. The input module 124 is used to detect user operation commands. Specifically, the input module 124 is located outside the box body 121 or cover 122 of the charging box 12. The input module 124 enables human-computer interaction and can be a button, capacitive touch, pressure-sensitive, etc.

[0032] The processing module 125 is connected to the input module 124 and is used to convert operation commands into control commands. Specifically, the processing module 125 is used to receive user operation commands detected by the input module 124 and, in response to the operation commands, convert the operation commands into corresponding control commands.

[0033] The first communication module 126 is connected to the processing module 125. The first communication module 126 is used to forward control commands to the wireless earphone 11 to control the wireless earphone 11 to perform corresponding operations. The wireless earphone 11 has a second communication module 111 and an execution module 112 that are connected to each other. The second communication module 111 can receive control commands forwarded by the first communication module 126 of the charging case 12, and the execution module 112 executes the control commands to make the earphone perform corresponding operations.

[0034] By configuring the input module 124, processing module 125, and first communication module 126 connected in sequence, the charging case 12 can control the wireless earphones 11 without opening the cover 122 of the charging case 12. The charging case 12 can detect the user's input operation commands at any time, convert the operation commands into control commands, and forward the control commands to the wireless earphones 11, thereby controlling the wireless earphones 11. Therefore, the charging case 12 can forward the user's control commands from the charging case 12 to the wireless earphones 11 in a communication manner, thereby controlling the wireless earphones 11 to perform corresponding operations and change the state of the wireless earphones 11.

[0035] In an optional embodiment, the operation instructions include at least one or a combination of a wake-up instruction, a pairing instruction, and a reset instruction. The wake-up instruction is used to control the wireless earphone 11 to switch from a sleep state to a working state. Initially, to save power consumption, the wireless earphone 11 may be in a sleep state, with most modules in the wireless earphone 11 in a non-working state. When the input module 124 detects the user's wake-up instruction, the processing module 125 converts the wake-up instruction into a control instruction to control the wireless earphone 11 to exit the sleep state. The first communication module 126 forwards the control instruction to the wireless earphone 11. The second communication module 111 of the wireless earphone 11 receives the control instruction and, through the execution module 112, switches the wireless earphone 11 from the sleep state to the working state.

[0036] The pairing command is used to control the wireless earphone 11 to perform Bluetooth pairing connection. When the input module 124 detects the user's pairing command, the processing module 125 converts the pairing command into a control command to control the Bluetooth pairing of the wireless earphone 11. The first communication module 126 forwards the control command to the wireless earphone 11. The second communication module 111 of the wireless earphone 11 receives the control command and, through the execution module 112, enables the wireless earphone 11 to perform Bluetooth pairing connection with the terminal device.

[0037] The reset command is used to control the wireless headset 11 to restore factory settings. When the input module 124 detects the user's reset command, the processing module 125 converts the reset command into a control command to control the wireless headset 11 to restore factory settings. The first communication module 126 forwards the control command to the wireless headset 11. The second communication module 111 of the wireless headset 11 receives the control command and uses the execution module 112 to restore the wireless headset 11 to factory settings.

[0038] By detecting wake-up commands, pairing commands, and reset commands through the input module 124 of the charging case 12, users can wake up, pair via Bluetooth, and restore factory settings of the wireless earphones 11 through the charging case 12 without opening the cover 122 of the charging case 12. The operation process is simple, the user experience is good, and it can effectively improve the user's efficiency and reduce the user's learning cost.

[0039] In another alternative embodiment, such as Figure 2 As shown, Figure 2 This is a schematic diagram of one structure of the charging box 12 in this embodiment. The user can also input an operation command to control the charging box 12. After the input module 124 detects the user's operation command, the processing module 125 converts the operation command into a control command. The control module 128 of the charging box 12 responds to the control command and controls the charging box 12 to perform the corresponding operation.

[0040] In another optional embodiment, initially, to conserve power, the charging case 12 is in a sleep state, and most modules, including the processing module 125 and the first communication module 126, are in a non-working state. Initially, the input module 124 is in a working state and can detect user commands at any time. Upon detecting a user command, the input module 124 generates a wake-up signal. The processing module 125 and the first communication module 126 respond to the wake-up signal, exiting the sleep state, and the charging case 12 switches from the sleep state to the working state.

[0041] In another alternative embodiment, such as Figure 3 As shown, Figure 3This is a schematic diagram of another structure of the earphone assembly 10 provided in one embodiment of this application. The charging case 12 also includes an indicator module 127, which is used to indicate the status of the charging case 12 and / or the wireless earphone 11. The indicator module 127 is connected to the processing module 125. The indicator module 127 may be a display screen, indicator light, etc.

[0042] The user inputs a control command for the earphones via the charging case 12. After the execution module 112 of the wireless earphones 11 performs the corresponding operation, the execution module 112 generates instruction information and forwards the instruction information to the charging case 12 via the second communication module 111 of the wireless earphones 11. The first communication module 126 of the charging case 12 can receive the instruction information forwarded by the second communication module 111. The processing module 125 generates an instruction command based on the instruction information received by the first communication module 126, and the instruction module 127 indicates the status of the wireless earphones 11 according to the instruction command.

[0043] The user inputs an operation command to control the charging box 12. After the control module 128 of the charging box 12 performs the corresponding operation, the control module 128 generates indication information. The processing module 125 generates indication instructions based on the indication information, and the indication module 127 indicates the status of the charging box 12 based on the indication instructions.

[0044] By setting the indicator module 127, the charging box 12 can control the wireless earphone 11 or the charging box 12 to perform corresponding operations after receiving the user's operation command, and indicate the status of the wireless earphone 11 and / or the charging box 12, so that the user can see the working status of the wireless earphone 11 and / or the charging box 12, which brings convenience to the user in using the charging box 12.

[0045] In another optional embodiment, the indicator module 127 can indicate the battery level of the wireless earphone 11. Specifically, the first communication module 126 can receive the battery level information of the wireless earphone 11 fed back by the second communication module 111 of the wireless earphone 11. The processing module 125 generates a battery level indication command for the wireless earphone 11 based on the battery level information of the wireless earphone 11. The indicator module 127 indicates the battery level of the wireless earphone 11 based on the battery level indication command, so that the user can directly see the battery level of the wireless earphone 11 through the indicator module 127 of the charging case 12.

[0046] In another optional embodiment, the indication module 127 can indicate the pairing status fed back by the wireless earphone 11. Specifically, the first communication module 126 can receive the pairing status of the wireless earphone 11 fed back by the second communication module 111 of the wireless earphone 11. The processing module 125 generates a pairing status command for the wireless earphone 11 based on the pairing status of the wireless earphone 11. The indication module 127 indicates the pairing status of the wireless earphone based on the pairing status command, so that the user can directly see the pairing status of the wireless earphone 11 through the indication module 127 of the charging case 12. Specifically, the indication module 127 can indicate the pairing status fed back by the wireless earphone 11 after the input module 124 detects the user's pairing command and the charging case 12 controls the wireless earphone 11 to perform Bluetooth pairing and connection with the terminal device. For example, the wireless earphone 11 can have two pairing states: paired and unpaired. The indication module can be an indicator light; when the charging case 12 receives paired status information from the wireless earphone 11, the indicator light displays green; when the charging case 12 receives unpaired status information from the wireless earphone 11, the indicator light displays red. Alternatively, the indicator module can be a display screen. The charging case 12 receives pairing status information from the wireless earphones 11 indicating that the earphones have been paired and connected, and the display screen shows the words "Earphones have been paired and connected"; the charging case 12 receives pairing status information from the wireless earphones 11 indicating that the earphones have not been paired and connected, and the display screen shows the words "Earphones have not been paired and connected".

[0047] In another alternative embodiment, such as Figure 4 As shown, the control module 128 may include a power detection module 1281 and a positioning detection module 1282. The power detection module 1281 is connected to the processing module 125 and is used to detect the power level of the battery in the charging case 12. The operation instructions also include power detection instructions. After the input module 124 detects the power detection instruction input by the user, the processing module 125 converts the power detection instruction into a power detection control instruction, and the power detection module 1281 detects the power level of the battery in the charging case 12 in response to the power detection control instruction. Furthermore, the indicator module 127 can also be used to indicate the power level of the charging case 12. The power detection module 1281 feeds back the power level information of the battery in the charging case 12 to the processing module 125. The processing module 125 generates a power level indicator instruction for the charging case 12 based on the power level information, and the indicator module 127 indicates the power level of the charging case 12 based on the power level indicator instruction, so that the user can directly see the power level of the charging case 12 through the indicator module 127. It is worth noting that the indicator module 127 can simultaneously display the battery level of the charging case 12 and the wireless earbuds 11.

[0048] In another optional embodiment, when the wireless earphone 11 cannot be directly observed from the outside of the charging case 12, the control module 128 may further include a positioning detection module 1282. The positioning detection module 1282 is connected to the processing module 125 and is used to detect whether the wireless earphone 11 is positioned (placed) inside the charging case 12. The operation instructions also include a positioning detection instruction. After the input module 124 detects the positioning detection instruction input by the user, the processing module 125 converts the positioning detection instruction into a positioning detection control instruction, and the positioning detection module 1282 detects whether the wireless earphone 11 is located inside the charging case 12 in response to the positioning detection control instruction. Furthermore, the indication module 127 can also be used to indicate the positioning status detected by the positioning detection module 1282. The positioning detection module 1282 feeds back the positioning status detected by the positioning detection module 1282 to the processing module 125. The processing module 125 generates a positioning status indication command based on the positioning status detected by the positioning detection module 1282. The indication module 127 then indicates the positioning status of the wireless earphone 11 according to the positioning status indication command. It is worth noting that the positioning detection command is not a necessary condition for the indication module 127 to indicate the positioning status of the wireless earphone 11. The indication module 127 can also be triggered directly after the wireless earphone 11 is positioned (placed) in the charging case 12.

[0049] In another optional embodiment, the operation instructions further include retrieval instructions and editing instructions. The retrieval instructions control the wireless earphone 11 to display a list of playback files stored internally, which is then shown by the indication module 127. In some cases, the wireless earphone 11 can function as an independent player, in addition to playing audio signals sent from connected external devices, allowing users to store a certain number of audio files on the wireless earphone 11 and play them according to user instructions. Therefore, when the input module 124 detects a user's retrieval instruction, the processing module 125 converts the retrieval instruction into a control instruction for the wireless earphone 11 to retrieve the playback file list. The first communication module 126 forwards this control instruction to the wireless earphone 11, and the second communication module 111 of the wireless earphone 11 receives the control instruction. The execution module 112 then controls the wireless earphone 11 to retrieve the internally stored playback file list and generates playback file list feedback information. The second communication module 111 forwards the playback file list feedback information to the first communication module 126. The charging box 12 indicates the playback file list feedback information through the indicator module 127, so that the user can see the playback file list stored inside the wireless earphone 11.

[0050] In another optional embodiment, the charging case 12 can function as a standalone player, allowing the user to store a certain number of audio files on it. The audio files in the charging case 12 can be forwarded to the wireless earphones 11 via the first communication module 126, enabling the wireless earphones 11 to play the audio files stored in the charging case 12. The operation instructions may further include playback instructions, which control the wireless earphones 11 to play one or more audio files stored in the charging case 12.

[0051] Editing commands can be used to control the wireless earphone 11 to perform corresponding editing operations on the playback files in the playback file list. When the input module 124 detects the user's editing command, the processing module 125 converts the editing command into a control command to control the wireless earphone 11 to perform corresponding editing operations on the playback files in the playback file list. The first communication module 126 forwards the control command to the wireless earphone 11. The second communication module 111 of the wireless earphone 11 receives the control command, and the execution module 112 controls the wireless earphone 11 to perform corresponding editing operations on the playback files in the playback file list. The editing commands may further include deletion commands, copy commands, playback order / mode modification commands, volume / sound quality adjustment commands, etc.

[0052] Please see Figure 5 , Figure 5 This is a flowchart illustrating a control method for a wireless earphone 11 provided in an embodiment of this application. In this embodiment, a control method for a wireless earphone 11 is provided, which can be specifically applied to the earphone assembly 10 involved in the above embodiment; specifically, the earphone assembly 10 may include earphones and an earphone case. The control method for the wireless earphone 11 includes:

[0053] Step S21: Detect the operation command input by the user through the charging box 12;

[0054] Specifically, the system detects the operation commands input by the user through the input module 124 of the charging box 12. Specifically, the charging box 12 has an input module 124 on the outside of the box body 121 or the cover 122. The input module 124 can perform human-computer interaction, and can be a button, capacitive touch, pressure sensing, etc.

[0055] Step S22: Convert the operation instructions into control instructions;

[0056] The processing module 125 is connected to the input module 124 and is used to convert operation commands into control commands. Specifically, the processing module 125 is used to receive user operation commands detected by the input module 124 and, in response to the operation commands, convert the operation commands into corresponding control commands.

[0057] Step S23: Forward the control command to the wireless earphone 11 to control the wireless earphone 11 to perform the corresponding operation.

[0058] The first communication module 126 is connected to the processing module 125. The first communication module 126 is used to forward control commands to the wireless earphone 11 to control the wireless earphone 11 to perform corresponding operations. The wireless earphone 11 has a second communication module 111 and an execution module 112 that are connected to each other. The second communication module 111 can receive control commands forwarded by the first communication module 126 of the charging case 12, and the execution module 112 executes the control commands to make the earphone perform corresponding operations.

[0059] The control method for the wireless earphone 11 provided in this embodiment allows the charging case 12 to control the wireless earphone 11 without opening the cover 122 of the charging case 12. The charging case 12 can detect user input commands at any time, convert the commands into control commands, and forward the control commands to the wireless earphone 11, thereby controlling the wireless earphone 11. Therefore, the charging case 12 can forward user control commands from the charging case 12 to the wireless earphone 11 via communication, thereby controlling the wireless earphone 11 to perform corresponding operations and change its state.

[0060] In another alternative embodiment, such as Figure 6 As shown, Figure 6 This is a flowchart of a control method for a wireless earphone 11 according to another embodiment of this application. The control method for the wireless earphone 11 further includes step S24: the charging case 12 switches from a sleep state to a working state. This step S24 is performed after step S21 and before step S22. In the initial state, to save power consumption, the charging case 12 is in a sleep state, and most modules, such as the processing module 125 and the first communication module 126, are in a non-working state. When the input module 124 detects a user's operation command, the charging case 12 switches from a sleep state to a working state, thereby waking up the modules in the charging case 12 and putting them into working mode.

[0061] The control method for the wireless earphone 11 also includes step S25: determining whether other operation commands input by the user are received within a specified time. The specified time can be a fixed value set at the factory or a preset time changed by the user. Other operation commands can be any one or more operation commands mentioned above. The other operation commands in step S25 and the operation commands in step S21 can be the same operation command or different operation commands.

[0062] If other operation commands input by the user are received within a specified time, the wireless earphone 11 is controlled to perform the corresponding operation. The control method for controlling the wireless earphone 11 to perform the corresponding operation is steps S21, S22, and S23. If no other operation commands input by the user are received within a specified time, the charging case 12 is controlled to switch from the working state to the sleep state. This method can reduce the power consumption of the charging case 12. The initial state is the sleep state, and the charging case 12 is switched from the sleep state to the working state only when the user's operation command is received. After the wireless earphone 11 performs the operation, if no other control commands are received after a period of time, the charging case 12 is switched from the working state to the sleep state, further reducing the power consumption of the charging case 12. If other control commands are received within a period of time, the charging case 12 can continue to perform the operation after receiving the operation command for the first time, preventing the charging case 12 from frequently switching between the sleep state and the working state in a short period of time.

[0063] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
