Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a wireless headphone system and a wireless headphone. Background Technology

[0002] In recent years, the appearance and experience of wearable products have received increasing attention. The demand for miniaturized wireless earbuds, such as true wireless stereo (TWS) earbuds, has become increasingly strong, and the relationship between earbuds and their charging cases (such as earbud cases) has become more and more diverse.

[0003] Currently, the relationship between the earphones and the charging case can be detected by placing a single-axis Hall sensor and a magnet at the corresponding position on the case. However, a single-axis Hall sensor can only be set to one threshold, primarily used to detect the presence or absence of a magnetic field, and its magnetic field threshold is not adjustable. This results in limited earphone position / status information, allowing only two state transitions: entering / leaving the case. Furthermore, the opening / closing status of the charging case must be detected and determined by the case itself, and communicated to the earphones via an electrical or signal connection mechanism (e.g., communication pins). Therefore, if the charging case malfunctions—for example, if it loses power or the pins connecting to the earphones are excessively corroded—it cannot promptly notify the earphones of the opening / closing status. This leads to delayed earphone power-on and inability to connect to mobile phones or other electronic devices immediately after the earphones are removed from the case, potentially causing dropped audio and impacting the user experience for calls and music playback. Summary of the Invention

[0004] In view of this, it is necessary to provide a wireless headphone system and wireless headphones that can independently detect multiple location / status information, effectively improving the user experience.

[0005] Firstly, this application provides a wireless earphone system. The wireless earphone system includes wireless earphones and a housing. The housing includes a lower cover, an upper cover, and a storage cavity, in which the wireless earphones can be stored. A first magnet is disposed on the upper cover. The wireless earphone includes a processor and a magnetic sensor coupled to the processor. The magnetic sensor is used to detect the magnetic field vector around the wireless earphones and transmit the detected magnetic field vector to the processor. The processor determines the state of the wireless earphones based on the received magnetic field vector, wherein the state of the wireless earphones includes at least a closed-in-the-case state, an open-in-the-case state, and an out-of-the-case state. Obviously, the wireless earphones can detect multiple position / state information of the earphones relative to the housing (e.g., at least the above three state information), and their detection can be independent of the housing. In this way, it can avoid the inability to notify the earphones in time due to abnormalities in the housing, which would prevent the earphones from connecting to mobile phones and other electronic products in time after being opened and removed from the housing, thus affecting the user experience of calls, music listening, etc. Through the solution of the embodiments of this application, the wireless earphones can independently determine their own state without relying on communication with the housing, thereby effectively improving the user experience.

[0006] In one possible design, the wireless earbuds can also control and power on / off based on the magnetic field vector detected by a magnetic sensor. In this design, the wireless earbuds can independently determine their own power on / off status and do not rely on communication with the charging case, thus effectively improving the user experience.

[0007] In one possible design, a second magnet is provided on the lower cover. Clearly, by adding a magnet, such as a second magnet, to the lower cover, the difference in the magnetic field vector detected by the magnetic sensor becomes more pronounced during opening, closing, and removal of the earphones from the case. This effectively increases the accuracy of the wireless earphone's status detection, resulting in more precise status detection. Furthermore, if the magnets (e.g., the first and second magnets) on the upper and lower covers have the same magnetic direction, the upper and lower covers can close quickly within a certain distance. The user would then need to overcome the attraction between the upper and lower covers to open the case smoothly, improving the tactile feedback when opening and closing the case.

[0008] In one possible design, a third magnet is provided on the top cover to magnetically attach the wireless earphones to it. Clearly, by including the third magnet on the top cover, the wireless earphones can be effectively magnetically attached to it.

[0009] In one possible design, the wireless earbuds' state also includes the open-case / closed-case state. The processor can determine the open-case / closed-case state based on the magnetic field vector. Clearly, by placing a third magnet on the case, the wireless earbuds can detect more position / state information, such as the open-case / closed-case state. This detection can be independent and does not rely on communication with the case, thus effectively improving the user experience.

[0010] In one possible design, the third magnet is spaced apart from the first magnet, or the third magnet is connected to the first magnet. Obviously, the first and third magnets can be independent magnets, spaced apart. Alternatively, the first and third magnets can be placed (or connected) together to form a single, large magnet. Alternatively, the third magnet can be omitted, and the size of the first magnet can be adjusted directly to form a large magnet. In other words, in this embodiment, by setting at least two magnets, at least four states can be detected.

[0011] In one possible design, the magnetic sensor is a triaxial Hall sensor. Clearly, by using a triaxial Hall sensor, the earphones can read the magnitude of the magnetic field along the x, y, and z axes. This not only allows for the detection of at least three positions / states of wireless earphones (e.g., earphones out of the case, earphones in the case with the lid closed, earphones in the case with the lid open), but also provides scalability for extending to multiple states, achieving multi-state detection in one device with strong scalability. Furthermore, by combining it with current electrical and wireless communication mechanisms (e.g., power on / off, battery level, binaural interaction, left / right ear recognition, etc.), more reliable and diverse state detection can be achieved. Moreover, by using a triaxial Hall sensor, this application demonstrates strong anti-interference capabilities, allowing for harsher external magnetic field environments, which the product can utilize to achieve a better user experience.

[0012] In one possible design, the magnetic sensor is positioned at the central axis of the wireless earphone. Clearly, by placing the magnetic sensor at the central axis of the wireless earphone, it is possible to accurately detect various position / state information without distinguishing between the earphone's orientation or whether it is the left or right ear. This overcomes the limitations of existing technologies that can only detect in a single direction and only detect earphones entering or leaving the case, achieving 360-degree rotation detection without blind spots.

[0013] In one possible design, the wireless earphones can rotate freely within the housing. Free rotation of the wireless earphones means that they can rotate at a certain angle (e.g., 45 degrees) or achieve 360-degree rotation within the housing.

[0014] In one possible design, the wireless earbuds also include a magnet for magnetically attaching to the charging case, allowing the earbuds to be stored within it. Clearly, this application, by incorporating a magnetic sensor, possesses strong anti-interference capabilities, allowing for harsher magnetic field environments, which the product can utilize to achieve a better user experience.

[0015] In one possible design, the case also features an adsorption magnet for closing the lower and upper covers. The magnet is positioned away from the wireless earbuds. Clearly, this application, by incorporating a magnetic sensor, offers strong anti-interference capabilities, allowing for harsher external magnetic field environments, which the product can utilize to achieve a better user experience. Furthermore, by keeping the magnet away from the earbuds, interference from the magnetic field generated by the magnet can be effectively prevented from affecting the magnetic induction intensity collected by the earbuds' magnetic sensor.

[0016] In one possible design, the box is an earphone case.

[0017] In one possible design, the housing serves as a carrier, which can be one of the following: a watch, glasses, necklace, bracelet, wristband, ring, power bank, adapter, handbag, suitcase, headband, tie, mobile phone, water cup, mouse, pen, notebook, racket, ball, or bicycle. The carrier and the wireless earphones constitute a fusion product. Clearly, the wireless earphones in this application are adaptable to TWS earphones and applicable to both existing and unrealized fusion products in the industry, such as earphones and watches, earphones and necklaces, and earphone cases with glasses. Furthermore, multi-level magnetic environment detection can be achieved for products of different forms. Moreover, by cooperating with the magnets in the housing, the magnetization direction can be optimized to make the detection more accurate.

[0018] Secondly, this application also provides a wireless earphone. The wireless earphone can be stored in a storage cavity of a case. The wireless earphone includes a processor and a magnetic sensor coupled to the processor; the magnetic sensor is used to detect the magnetic field vector around the wireless earphone and transmit the detected magnetic field vector to the processor; the processor determines the state of the wireless earphone based on the received magnetic field vector, wherein the state of the wireless earphone includes at least a closed-in-case state, an open-in-case state, and an unopened-in-case state.

[0019] In one possible design, the magnetic sensor is a triaxial Hall sensor.

[0020] In one possible design, the magnetic sensor is positioned at the central axis of the wireless earphone.

[0021] In one possible design, the wireless earphones can rotate freely within the storage cavity.

[0022] In one possible design, the wireless earphones are cylindrical or near-cylindrical in shape.

[0023] In one possible design, the wireless earphones also include a magnet for attracting the housing so that the wireless earphones are housed within the housing.

[0043] Explanation of main component symbols

[0044]

[0045]

[0046] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0048] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set", "connected", and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In recent years, the appearance and experience of wearable products have received increasing attention. The demand for miniaturized wireless earbuds, such as true wireless stereo (TWS) earbuds, has become increasingly strong, and the relationship between earbuds and their charging cases (such as earbud cases) has become more and more diverse.

[0051] Currently, the state relationship between the earphones and the housing can be detected by placing a single-axis Hall sensor and a magnet at the corresponding position on the housing. For an example, please refer to [link / reference]. Figure 1a In the first scenario, when the user opens the case, the case detects the opening event and wakes up the earphones, at which point the earphones are in the open-case-and-place state. Then, when the user removes the earphones, the earphones detect the exit event, at which point the earphones are in the exit-case-and-place state.

[0052] Please refer to the following: Figure 1b In the second scenario, when the user inserts the earbuds, the earbuds detect an "insertion into case" event, and are in the "open case" state. Then, when the user closes the case, the case detects a "closed case" event and notifies the earbuds, putting them in the "closed case" state. Simultaneously, the case notifies or controls the earbuds to power off to conserve battery power.

[0053] Clearly, in the above solution, the earphone's power-on status is limited by the charging case; that is, the charging case needs to detect the opening event and wake up the earphones via an electrical connection mechanism (e.g., charging pin). If the charging case malfunctions, for example, when it runs out of power or the pins connecting to the earphones are excessively corroded, the charging case cannot promptly notify the earphones of the detected opening status, leading to a delay in the earphone's power-on. Consequently, the earphones cannot connect to mobile phones or other electronic devices immediately after being removed from the case, easily causing dropped audio and affecting the user experience for calls and music playback. Furthermore, the earphone's status determination cannot be independent of the charging case. After powering on, the earphones need to obtain the charging case's status (e.g., whether the case is open or closed) and must interact with the charging case via an electrical connection mechanism (e.g., charging pin); that is, the earphone's status determination depends on the charging case's electrical communication mechanism. Additionally, as users focus on user experience, many products add magnets to achieve a better experience, leading to increasingly complex magnetic field environments, which significantly increases the challenge for single-axis Hall effect sensors. Therefore, for projects / products with complex magnetic field environments, existing earphone position / status information detection solutions are insufficient to meet the development needs of product functions.

[0054] Therefore, this application provides a wireless earphone and a wireless earphone system. The wireless earphone can detect the position / state information of various earphones relative to the charging case, and this detection is independent of the charging case. This avoids the inability to promptly notify the earphones due to abnormalities in the charging case, thus preventing the earphones from connecting to mobile phones or other electronic devices immediately after being opened and removed from the case, affecting the user experience for calls and music playback. The solution in this application allows the earphones to independently determine their own state without relying on communication with the charging case, thereby effectively improving the user experience. Furthermore, the wireless earphone in this application reduces the earphones' requirements for the magnetic and electrical environment of the charging case, simplifying product design and reliably detecting the state of various earphones relative to the charging case.

[0055] Please see Figure 2a This illustration shows a schematic diagram of a wireless earphone system provided in an embodiment of this application. Figure 2a As shown, the wireless headphone system 100 may include a wireless headphone 11 and a housing 12.

[0056] The wireless earphones 11 include a pair of earphone bodies that can be used with the user's left and right ears, such as a pair of earphone bodies 111. The wireless earphones 11 can be earbuds, over-ear earphones, or in-ear earphones, etc. For example, the wireless earphones 101 can be true wireless stereo (TWS) earphones. For example, the charging case 12 is an earphone case used to store the earphone bodies 111. For example, the charging case 12 includes two storage cavities 121. The storage cavities 121 are used to store the earphone bodies 111.

[0057] It should be noted that, Figure 2a The schematic diagram illustrating one product form of a wireless earphone system is provided by way of example only. The wireless earphones provided in this application include, but are not limited to, [examples of wireless earphones]. Figure 2a The wireless earphone 11 shown includes, but is not limited to, the housing. Figure 2a The box 12 shown. For example, the wireless earphone system provided in the embodiments of this application can also be Figure 2b The wireless headphone system 200 shown is an example. Figure 2b As shown, the wireless earphone system 200 includes wireless earphones 21 and a housing 22. The wireless earphones 21 include two earphone bodies 211. The housing 22 includes a housing cavity 221 for housing the earphone bodies 211. Of course, in some embodiments, the wireless earphones may also include only one earphone body, which will not be described in detail here.

[0058] Please see Figure 3 , Figure 3 A schematic diagram of the structure of a wireless earphone body 300 is shown. The earphone body 300 can be stored in a case. The earphone body 300 may include a processor 301, a memory 302, a sensor module 303, a wireless communication module 304, an audio module 305, a power module 306, and multiple input / output interfaces 307, etc.

[0059] The processor 301 may include one or more interfaces for connecting to other components of the headphone body 300. For example, these interfaces may include: I / O interfaces (also called I / O pins), interrupt pins, and data bus interfaces. The data bus interface may include one or more of SPI, I2C, and I3C interfaces. For instance, in this embodiment, the processor 301 can connect to a magnetic sensor via I / O pins, interrupt pins, or the data bus interface.

[0060] The memory 302 can be used to store program code, such as program code for charging the earphone body 300, wireless pairing and connection between the earphone body 300 and other electronic devices, or wireless communication between the earphone body 300 and electronic devices. The memory 302 can also store a Bluetooth address for uniquely identifying the wireless earphone. Additionally, the memory 302 can store connection data of electronic devices previously successfully paired with the wireless earphone. For example, this connection data can be the Bluetooth address of an electronic device that has been successfully paired with the wireless earphone. Based on this connection data, the wireless earphone can automatically pair with the electronic device without needing to configure the connection, such as performing authentication. The aforementioned Bluetooth address can be a media access control (MAC) address. The processor 301 can be used to execute the aforementioned application code, calling relevant modules to implement the functions of the earphone body 300 in this embodiment. For example, implementing the charging function, wireless communication function, audio data playback function, and location / status information detection function (e.g., opening and closing the case and entering / exiting the box). The processor 301 can include one or more processing units, which can be independent devices or integrated into one or more processors 301. The processor 301 may be an integrated control chip or a circuit comprising various active and / or passive components, and the circuit is configured to perform the functions of the processor 301 described in the embodiments of this application. The processor of the earphone body 300 may be a microprocessor.

[0061] Sensor module 303 includes magnetic sensor 303A. Magnetic sensor 303A is used to detect the magnetic field around the earphone body 300. Processor 301 can execute the method of this embodiment to detect various states of the earphone body 300, such as insertion / removal from the case, opening / closing the cover, etc., based on changes in the magnetic field detected by magnetic sensor 303A. For example, magnetic sensor 303A is a triaxial Hall sensor.

[0062] It should be understood that in other embodiments, the sensor module 303 may also include other sensors, which are not limited herein. For example, the sensor module 303 may also include a distance sensor and / or a proximity light sensor. The processor 301 can determine whether the earphone body 300 is being worn by a user based on data collected by the distance sensor or the proximity light sensor. For example, the processor 301 can use data collected by the distance sensor to detect whether there is an object near the earphone body 300, thereby determining whether the earphone body 300 is being worn by a user. When it is determined that the earphone body 300 is being worn, the processor 301 can turn on the speaker of the earphone body 300. As another example, the sensor module 303 may also include a bone conduction sensor. The earphone body 300 combined with the bone conduction sensor constitutes a bone conduction earphone. For example, using the bone conduction sensor, the processor 301 can acquire the vibration signal of the sound-emitting bone block, parse the voice signal, and realize the voice function. As another example, the sensor module 303 may also include a touch sensor, a fingerprint sensor, an ambient light sensor, and / or other sensors. For example, a touch sensor is disposed on the outer surface of the earphone body 300 for detecting the user's touch operation. Fingerprint sensors are used to detect a user's fingerprint and identify the user. Ambient light sensors can adaptively adjust parameters (such as volume) based on the perceived brightness of the ambient light.

[0063] The wireless communication module 304 can be used to support data exchange between the earphone body 300 and other electronic devices or housings, including Bluetooth (BT), Global Navigation Satellite System (GNSS), Wireless Local Area Networks (WLAN) (such as Wireless Fidelity (Wi-Fi) networks), Frequency Modulation (FM), Near Field Communication (NFC), and Infrared (IR) technologies. For example, the wireless communication module 304 can be a Bluetooth chip. The earphone body 300 can pair with and establish a wireless connection with the Bluetooth chips of other electronic devices through the Bluetooth chip, thereby enabling wireless communication between the earphone body 300 and other electronic devices. For example, in this embodiment, the wireless communication module 304 can be used to send the remaining battery power of the housing to the electronic device with which the earphone body 300 has established a wireless connection (such as a Bluetooth connection) after the processor 301 determines that the earphone body 300 has been removed from the housing.

[0064] In addition, the wireless communication module 304 may also include an antenna. The wireless communication module 304 receives electromagnetic waves through the antenna, modulates and filters the electromagnetic wave signal, and sends the processed signal to the processor 301. The wireless communication module 304 may also receive signals to be transmitted from the processor 301, modulate and amplify them, and then convert them into electromagnetic waves for radiation through the antenna.

[0065] The audio module 305 can be used to manage audio data and enable the input and output of audio signals to the headset body 300. For example, the audio module 305 can acquire audio signals from or transmit audio signals to the wireless communication module 304, enabling functions such as making and receiving calls, playing music, activating / deactivating the voice assistant of an electronic device connected to the headset, and receiving / sending user voice data through the headset body 300. The audio module 305 may include a speaker (or earpiece, receiver) assembly for outputting audio signals, a microphone (or microphone, transducer), and a microphone recording circuit that works with the microphone. The speaker can be used to convert audio electrical signals into sound signals and play them. The microphone can be used to convert sound signals into audio electrical signals. The audio module 305 (such as a speaker, also called a "horn") includes a magnet. The magnetic field around the headset body 300 includes the magnetic field generated by this magnet. The magnetic field generated by this magnet affects the magnitude of the magnetic induction intensity collected by the magnetic sensor 303A of the headset body 300.

[0066] The power module 306 provides system power to the earphone body 300, supplying power to its various modules. It also supports the earphone body 300 in receiving charging inputs. The power module 306 may include a power management unit (PMU) and a battery (i.e., the first battery). The PMU may include a charging circuit, a voltage drop regulation circuit, a protection circuit, and a power measurement circuit. The charging circuit receives external charging inputs. The voltage drop regulation circuit transforms the electrical signal input to the charging circuit and outputs it to the battery to complete charging. It can also transform the electrical signal input from the battery and output it to other modules such as the audio module 305 and the wireless communication module 304. The protection circuit prevents overcharging, over-discharging, short circuits, or overcurrent. In some embodiments, the power module 306 may also include a wireless charging coil for wirelessly charging the earphone body 300. Additionally, the power management unit can monitor parameters such as battery capacity, battery cycle count, and battery health status (leakage, impedance).

[0067] Multiple input / output interfaces 307 can be used to provide a wired connection for charging or communication between the earphone body 300 and the housing. For example, the input / output interface 307 may include an earphone electrical connector. The earphone electrical connector is used to conduct and transmit current. When the earphone body 300 is placed inside the housing's storage cavity, the earphone body 300 can establish an electrical connection with an electrical connector in the housing via the earphone electrical connector (e.g., the earphone electrical connector makes direct contact with the electrical connector in the housing). After this electrical connection is established, the housing can charge the battery in the earphone body 300 through the current transmission function of the earphone electrical connector and the electrical connector in the housing. For example, the earphone electrical connector can be a pogo pin, spring pin, spring contact, conductive block, conductive patch, conductive sheet, pin, plug, contact pad, jack, or socket, etc. The specific type of electrical connector is not limited in this application embodiment. In other embodiments, after the electrical connection is established, the earphone body 300 can also communicate data with the housing, for example, it can receive pairing commands from the housing.

[0068] It is understood that the structure illustrated in the embodiments of this application does not constitute a specific limitation on the headphone body 300. It may have a more... Figure 3 The illustrated components may include more or fewer parts, two or more parts may be combined, or different component configurations may be used. For example, the earphone body 300 may also have a magnet (such as a magnetic magnet) on its shell for attaching to the charging case, allowing the earphone body 300 to be housed within the case. The magnetic field around the earphone body 300 includes the magnetic field generated by this magnet. The magnetic field generated by this magnet affects the magnetic field vector (including magnetic field strength / magnitude and magnetic field direction) collected by the magnetic sensor 303A of the earphone body 300. As another example, the outer surface of the earphone body 300 may also include components such as buttons, indicator lights (indicating battery level, incoming / outgoing calls, pairing mode, etc.), a display screen (displaying relevant user information), and a dust filter (for use with the earpiece). The buttons may be physical buttons or touch buttons (used in conjunction with a touch sensor), used to trigger operations such as power on / off, pause, play, record, start charging, and stop charging.

[0069] Please see Figure 4 , Figure 4 A schematic diagram of a wireless earphone case 400 is shown. The case 400 is used to store the earphone body. The case 400 may include a lower cover 401 and an upper cover 402. The lower cover 401 and the upper cover 402 can be fastened together to store the earphone body. For example, the case 400 includes two storage cavities 403a and 403b. The two storage cavities 403a and 403b are respectively used to store the corresponding earphone body.

[0070] It is understood that in some embodiments, the housing 400 may contain one or more magnets. For example, the one or more magnets may include a first magnet and a second magnet. The first magnet and the second magnet are correspondingly configured with the magnetic sensor of the wireless earphone, so that when the wireless earphone is placed in the housing, the magnetic sensor of the wireless earphone can sense the vector generated by the first magnet and the second magnet. The first magnet is disposed on the upper cover 402, and the second magnet is disposed on the lower cover 401, both corresponding to the magnetic sensor of the wireless earphone. For example, the first magnet and the second magnet are respectively disposed on the upper cover 402 and the lower cover 401, and are disposed corresponding to the receiving cavities 403a and 403b of the housing 400. Thus, when the earphone is stored in the receiving cavities 403a and 403b of the housing 400, the magnetic field around the earphone includes at least the magnetic field generated by the first magnet and the second magnet. The magnetic field generated by the first magnet and the second magnet affects the magnetic field vector collected by the magnetic sensor of the earphone.

[0071] It is understood that, in the embodiments of this application, the quantity, shape, size, and other parameters of the first and second magnets are not limited. For example, such as... Figure 4 As shown, the housing 400 can provide one first magnet and one second magnet for each earphone body. For example, a first magnet 405a and a second magnet 404a are provided for the earphone body corresponding to the left storage cavity 403a, and a first magnet 405b and a second magnet 404b are provided for the earphone body corresponding to the right storage cavity 403b. Of course, the number of first magnets and second magnets provided by the housing 400 for each earphone body can be adjusted according to specific circumstances, as long as it is ensured that the magnetic field generated by the first magnet and the second magnet affects the magnetic field vector collected by the magnetic sensor of the earphone body. For example, in other embodiments, the housing 400 can provide two or more first magnets and two or more second magnets for each earphone body.

[0072] It is understood that the specific placement of the first and second magnets is not limited in the embodiments of this application. For example, the first and second magnets may also be disposed between the two receiving cavities 403a and 403b, so that the two earphone bodies can share the same first and second magnets. For example, in one embodiment, one first magnet and one second magnet may be provided. The first and second magnets are disposed in the middle position or other suitable position of the two earphone bodies, so that the magnetic sensors in both earphone bodies can collect the magnetic field generated by the first and second magnets.

[0073] It is understood that in this embodiment of the application, the second magnet may be omitted from the housing 400, that is, only the first magnet is provided on the upper cover 402. It is only necessary to ensure that the magnetic field generated by the first magnet will affect the magnetic field vector collected by the magnetic sensor of the earphone body.

[0074] It is understood that, in the embodiments of this application, the housing 400 may also have one or more other magnets inside. For example, magnets for attracting wireless earphones (such as the earphone body of wireless earphones) so that the wireless earphones are housed in the housing cavities 403a, 403b; and / or magnets for attracting the lower cover 401 and the upper cover 402 of the housing 400 to close, etc., are not limited here.

[0075] It is understood that in this embodiment, the housing 400 may further include a housing power module and multiple input / output interfaces. The housing power module can supply power to the electrical components in the housing 400, and may include a housing battery (i.e., a second battery). In some embodiments, the input / output interfaces may be housing electrical connectors, which are electrically connected to the electrodes of the housing power module and can be used to conduct and transmit current. For example, the housing 400 may include two pairs of housing electrical connectors corresponding to two earphone bodies, respectively. When a pair of housing electrical connectors in the housing 400 establishes an electrical connection with two earphone electrical connectors in the earphone body, the housing 400 can charge the battery in the earphone body using its own housing battery.

[0076] It is understood that in some other embodiments, at least one touch control may also be provided on the housing 400, which can be used to trigger functions such as pairing reset of the wireless earbuds or charging of the wireless earbuds. The housing 400 may also be provided with one or more power indicator lights to indicate to the user the battery level in the housing 400 and the battery level in each earbud body in the housing 400.

[0077] It is understood that in other embodiments, the housing 400 may also include components such as a processor, memory, charging interface, and wireless charging coil, which will not be described in detail here.

[0078] The wireless earphone and its location information detection method in the following embodiments can both be implemented in a wireless earphone with the above-described hardware structure. For example, Embodiments 1 and 2 will be used as examples to describe the implementation methods of this application in conjunction with the accompanying drawings.

[0079] Example 1:

[0080] Embodiment 1 of this application provides a wireless earphone. Please refer to it as well. Figures 5a to 5f ,in, Figure 5a This is a diagram showing the wireless earphones placed inside the case. Figure 5b for Figure 5a The image shows a sectional view along line AA of the wireless earphones after they have been placed in the earphone case. Figure 5c for Figure 5a The diagram shows the hardware structure of the earphone body in the wireless earphone. Figure 5d for Figure 5aThe diagram shows the wireless earphones in the case-opening and case-placed state. Figure 5e for Figure 5a The diagram shows the wireless earphones in the case-out state. Figure 5f for Figure 5a The diagram shows the location of the magnetic sensor in the wireless earphone.

[0081] The wireless earphones consist of two earphone units, 500a and 500b. Both earphone units, 500a and 500b, are housed within the charging case 600. Figures 5a to 5d As shown, the housing 600 includes a lower cover 601 and an upper cover 602. The lower cover 601 and the upper cover 602 can be fastened together to house the earphone bodies 500a and 500b. For example, the housing 600 includes two storage cavities 603a and 603b. The two storage cavities 603a and 603b can be used to house the corresponding earphone bodies. For example, storage cavity 603a is used to house earphone body 500a, and storage cavity 603b is used to house earphone body 500b.

[0082] For example, in this embodiment of the application, the housing 600 is provided with a first magnet and a second magnet for each earphone body 500a and 500b. For instance, earphone body 500a is provided with a first magnet 605a and a second magnet 604a, and earphone body 500b is provided with a first magnet 605b and a second magnet 604b. It is understood that, for ease of description, the following embodiments will use the left-side storage cavity 603a, earphone body 500a, first magnet 605a, and second magnet 604a as examples for illustration.

[0083] The first magnet 605a is disposed on the upper cover 602, and the second magnet 604a is disposed on the lower cover 601, both corresponding to the earphone body 500a. For example, the first magnet 605a and the second magnet 604a are respectively disposed on the upper cover 602 and the lower cover 601, corresponding to the storage cavity 603a of the housing 600. Thus, when the earphone body 500a is stored in the storage cavity 603a, the magnetic field around the earphone body 500a includes at least the magnetic fields generated by the first magnet 605a and the second magnet 604a. The magnetic fields generated by the first magnet 605a and the second magnet 604a affect the magnetic field vector collected by the magnetic sensor of the earphone body 500a (details below).

[0084] It is understood that, in the embodiments of this application, the positions of the first magnet 605a and the second magnet 604a relative to the earphone body 500a are not limited. For example, as Figure 5a The first magnet 605a and the second magnet 604a on the left side can be symmetrically arranged relative to the left earphone body 500a.

[0085] For example, such as Figure 5bAs shown, the housing 600 is also provided with an adsorption magnet 606. The adsorption magnet 606 is used to achieve the closed adsorption of the lower cover 601 and the upper cover 602 of the housing 600. In this embodiment, the specific position of the adsorption magnet 606 on the housing 600 is not limited. For example, the adsorption magnet 606 can be provided on the lower cover 601 or the upper cover 602. Correspondingly, the upper cover 602 or the lower cover 601 is provided with a corresponding magnet, soft magnet, etc., to cooperate with the adsorption magnet 606 to achieve the closed adsorption of the lower cover 601 and the upper cover 602. As another example, the adsorption magnet 606 can be provided at a position in the housing 600 away from the storage cavity 603 to prevent the magnetic field generated by the adsorption magnet 606 from interfering with the magnetic induction intensity collected by the magnetic sensor of the earphone body 500.

[0086] It is understood that the type and shape of the earphone body 500a are not limited in the embodiments of this application. For example, the earphone body 500a can be an earbud, over-ear, or in-ear earphone. As another example, the shape of the earphone body 500a can be cylindrical, quasi-cylindrical (e.g., bullet-shaped), etc. (see...) Figure 5b It is understandable that when the earphone body 500a is cylindrical or near-cylindrical, it can rotate freely within the storage cavity 603a of the housing 600. The position of the earphone body 500a within the storage cavity 603a does not affect the three-axis Hall sensor within the earphone body 500a's detection of the earphone's entry into the case, exit from the case, opening, and closing states. The free rotation of the earphone body 500a means that it can rotate at a certain angle (e.g., 45 degrees) or achieve 360-degree rotation within the storage cavity 603a.

[0087] Please refer to the following: Figure 5c The headphone body 500a may include a magnetic sensor 501 and a processor 502. The magnetic sensor 501 is coupled to the processor 502. It can be understood that when the headphone body 500a is... Figure 3 When the earphone body 300 is shown, the magnetic sensor 501 can be... Figure 3 The magnetic sensor 303A shown can be processed by a processor 502. Figure 3 The processor 301 is shown. The functions and connection relationships of the magnetic sensor 501 and the processor 502 can be found in [reference needed]. Figure 3 The embodiments shown are not described in detail here.

[0088] It is understood that in this embodiment of the application, the magnetic sensor 501 is a triaxial Hall sensor, which is used to detect the magnetic field vector (e.g., the magnitude of the magnetic field along the x, y, and z axes) around the headphone body 500, and transmit the detected magnetic field vector to the processor 502.

[0089] For example, when the earphone body 500a is stored in the storage cavity 603a of the case 600, and the case 600 is closed (see...). Figure 5a and Figure 5b When the headphone body 500a is in use, the magnetic field around it can include at least the magnetic field generated by the magnet in the headphone body 500a and the magnetic field generated by the housing 600, that is, the combined magnetic field generated by the magnet in the headphone body 500a and the magnet in the housing 600. For example, the magnetic field generated by the magnet in the headphone body 500a can include the magnetic field generated by the magnet in the speaker (also called a "horn"). The magnetic field generated by the housing 600 includes at least the magnetic field generated by the first magnet 605a and the magnetic field generated by the second magnet 604a.

[0090] Optionally, the magnetic field generated by the magnet in the earphone body 500a may further include: a magnetic field generated by the magnet used to attract the housing 600, allowing the earphone body 500a to be housed within the housing cavity 603a of the housing 600. The magnetic field generated by the housing 600 may also include a magnetic field generated by the magnet 606 used for the closing attraction between the lower cover 601 and the upper cover 602. Optionally, the magnetic field generated by the housing 600 may further include a magnetic field generated by the magnet used to attract the earphone body 500a, allowing the earphone body 500a to be housed within the housing cavity 603a of the housing 600, and a magnetic field generated by a magnet used to enhance the pressure between the charging pins of the housing 600 and the earphone body 500a. The charging pins of the housing 600 and the earphone body 500a may be electrical connectors between the housing 600 and the earphone body 500a.

[0091] Similarly, please refer to the following: Figure 5d When the earphone body 500a is stored in the storage cavity 603a of the housing 600 and the housing 600 is opened, the magnetic field around the earphone body 500a can include at least the magnetic field generated by the magnet in the earphone body 500a and the magnetic field generated by the housing 600, that is, the combined magnetic field generated by the magnet in the earphone body 500a and the magnet in the housing 600.

[0092] Please refer to the following: Figure 5e When the earphone body 500a is outside the housing 600, the magnetic field around the earphone body 500a can include the magnetic field generated by the magnet in the earphone body 500a.

[0093] Of course, when the earphone body 500a is placed outside the case 600, but the distance between the earphone body 500a and the case 600 is relatively close, the magnet in the case 600 will also affect the magnetic field around the earphone body 500a. However, compared to the state inside the case (including the closed and open states), the influence of the magnet in the case 600 on the magnetic field around the earphone body 500a is relatively small and can be ignored when the earphone body 500a is out of the case. In this embodiment, for ease of description, the influence of the magnet in the case 600 on the magnetic field around the earphone body 500a is ignored when the earphone body 500a is out of the case.

[0094] In summary, when the earphone body 500a is in the closed-case state, the magnetic sensor 501 can detect the combined magnetic field vector (hereinafter referred to as the first magnetic field vector) generated by the magnet in the earphone body 500a and the magnet in the case 600. When the earphone body 500a is in the open-case state, the magnetic sensor 501 can also detect the combined magnetic field vector (hereinafter referred to as the second magnetic field vector) generated by the magnet in the earphone body 500a and the magnet in the case 600. When the earphone body 500a is out of the case, the magnetic sensor 501 can detect the magnetic field vector (hereinafter referred to as the third magnetic field vector) generated by the magnet in the earphone body 500a.

[0095] It is understandable that when the earphone body 500a is in the open-case-placed state, since the top cover 602 is open, the influence of the magnet on the top cover 602 on the earphone body 500a in the open-case-placed state is less than the influence of the magnet on the earphone body 500a in the closed-case-placed state. That is, the first magnetic field vector and the second magnetic field vector are not the same. Furthermore, since the magnetic sensor 501 can only detect the magnetic field vector generated by the magnet inside the earphone body 500a when the earphone body 500a is out of the case, the third magnetic field vector is also different from the first and second magnetic field vectors.

[0096] Therefore, it can be seen that the magnetic field vector detected by the magnetic sensor 501 is different when the earphone body 500a is in different states (such as closed case, open case, or out of case). Thus, in this embodiment, the wireless earphone can detect the corresponding magnetic field vector through the magnetic sensor 501, and the processor 502 can process the magnetic field vector to determine or detect the position information of the wireless earphone, such as whether the wireless earphone is in a closed case, open case, or out of case state.

[0097] For example, the processor 502 processes the aforementioned magnetic field vector, which can be, but is not limited to, pre-setting different vector thresholds corresponding to different states. Thus, when the processor 502 determines that the magnetic field vector sensed by the magnetic sensor 501 meets the preset vector threshold, it indicates that the earphone body 500a is in the corresponding state. For instance, it can be set that when the processor 502 determines that the magnetic field vector sensed by the magnetic sensor 501 meets the first vector threshold, the earphone body 500a is in the closed-case state. When the processor 502 determines that the magnetic field vector sensed by the magnetic sensor 501 meets the second vector threshold, the earphone body 500a is in the open-case state. When the processor 502 determines that the magnetic field vector sensed by the magnetic sensor 501 meets the third vector threshold, the earphone body 500a is in the unopened-case state.

[0098] It is understandable that the wireless earphones utilize a magnetic sensor 501, a triaxial Hall sensor, to determine various complex positions such as when the earphones are closed and placed in the case, open and placed in the case, or out of the case, based on changes in the magnetic field under different states. This reduces the earphones' requirements for the magnetic and electrical environment of the case 600, simplifying product design and reliably detecting the earphones' relative positions to the case. Furthermore, the detection results will not be misjudged due to problems with the electrical connection mechanism between the case 600 and the earphone body 500a, or corrosion of the electrical connection pins. In other words, the detection of magnetic induction intensity and the determination of position / state information can be independent of the case 600 and does not depend on the electrical connection between the case 600 and the wireless earphones. Even if the electrical connection mechanism between the case 600 and the wireless earphones malfunctions, or the electrical connection pins are corroded, the wireless earphones can still obtain their own position / state information in a timely manner and then perform corresponding operations based on this information, such as controlling the power on / off of the earphones or controlling automatic pairing between the earphones and electronic devices. In addition, the wireless earphones can also resist interference from the magnetic environment outside the case, resulting in higher reliability.

[0099] It is understood that in other embodiments, the wireless earphones can also control and realize the power on / off of the wireless earphones based on the magnetic field vector detected by the magnetic sensor 501. In this way, the wireless earphones can independently determine their own power on / off status and state, without relying on communication with the housing 600, thereby effectively improving the user experience.

[0100] I understand, please refer to the above as well. Figure 5fFor example, the magnetic sensor 501 is positioned at the central axis of the earphone body 500a. In this way, the wireless earphone can detect various position / state information of the earphone without distinguishing the orientation of the earphone body 500a or the left / right ear. Furthermore, by setting the magnetic sensor 501 as a triaxial Hall sensor and positioning it at the central axis of the earphone body 500a, the aforementioned position / state information can be accurately detected even when the earphone body 500a rotates freely within the housing cavity 603. Of course, in other embodiments, the position of the magnetic sensor 501 is not limited to this; it can be adjusted according to actual conditions and is not limited here.

[0101] It is understood that in this embodiment, in order to make the difference in the magnetic field vector detected by the magnetic sensor 501 more obvious when the earphone body 500a is in different states (e.g., closed and placed in the case, open and placed in the case, or removed from the case), the number, size, etc. of the first magnet 605 and the second magnet 604 can be adjusted as needed, or multiple other magnets can be provided in the case 600.

[0102] It is understood that in other embodiments, the second magnet 604a may be omitted depending on the actual situation. That is, the first magnet 605a is only provided on the upper cover 602 of the housing 600. The earphone body 500a can also use the first magnet 605a to determine or detect the position / status information of the wireless earphone.

[0103] Of course, in this embodiment, by adding a magnet, such as a second magnet 604a, to the lower cover 601, the difference in the magnetic field vector detected by the magnetic sensor 501 can be made more obvious, thereby effectively increasing the accuracy of the wireless earphone's status detection, thus achieving a more accurate status detection effect for the wireless earphone. Furthermore, [the following is a continuation of the previous sentence] Figure 5b If the magnets (such as the first magnet 605a and the second magnet 604a) on the upper cover 602 and the lower cover 601 have the same magnetic direction, the upper cover 602 and the lower cover 601 can be effectively closed, which increases the feel.

[0104] Example 2:

[0105] Embodiment 2 of this application provides a wireless earphone. Please refer to it as well. Figures 6a to 6e The wireless earphones consist of two earphone bodies, 700a and 700b. The two earphone bodies, 700a and 700b, are housed inside the charging case 800.

[0106] Understandable, such as Figures 6a to 6eAs shown, the difference between Embodiment 2 and Embodiment 1 is that, in addition to the first magnet 805a and the second magnet 804a, the housing 800 also has a third magnet 807a corresponding to the earphone body 700a. The third magnet 807a is disposed on the upper cover 802 to attract the earphone body 700a to the upper cover 802. Alternatively, the third magnet 807a can also cooperate with the first magnet 805a to attract the earphone body 700a to the upper cover 802. Of course, in other embodiments, the wireless earphone is not limited to using the third magnet 807a to attract the earphone body 700a; other attraction structures can also be used to attract the earphone body 700a to the upper cover 802.

[0107] It is understood that, compared to Embodiment 1, Embodiment 2 has a third magnet 807a on the housing 800. Therefore, the earphone body 700a has at least four states: closed and inserted into the housing, open and inserted into the housing (including the open and inserted state with the lower cover and the open and inserted state with the upper cover), and removed from the housing. For example, ... Figure 6a and Figure 6b As shown, the earphone body 700a is in the closed case position. Figure 6c As shown, the earphone body 700a is in the open case / case position with the top cover on. Figure 6d As shown, the earphone body 700a is in the open case / case position with the bottom cover on. Figure 6e As shown, the earphone body 700a is in the unpacked state.

[0108] Similar to Embodiment 1, the magnetic field vector detected by the earphone body 700a is different when it is in different states (e.g., closed and placed in the case, open and placed in the case with the bottom cover, open and placed in the case with the top cover, or out of the case). Therefore, in Embodiment 2, the wireless earphone can detect different magnetic field vectors and process them to determine or detect the position / state information of the earphone, such as when the earphone is in the closed and placed in the case, open and placed in the case with the bottom cover, open and placed in the case with the top cover, or out of the case.

[0109] It is understood that in the above embodiments, the second magnet 804a and the third magnet 807a are independent magnets, arranged alternately. Of course, in other embodiments, the first magnet 805a and the third magnet 807a can also be combined. For example, as in Embodiment 1, the first magnet 805a and the third magnet 807a can be arranged (or connected) together to form a single unit, i.e., a large magnet. As another example, in other embodiments, the third magnet 807a can be omitted, and the size of the first magnet 805a can be directly adjusted to extend to the position of the third magnet 807a in the figure, thereby forming a large magnet. In other words, in the embodiments of this application, by setting at least two magnets (e.g., the first magnet and the second magnet), at least four states can be detected.

[0110] It is understood that the other parts of Embodiment 2 are similar to Embodiment 1. For details, please refer to Embodiment 1, which will not be repeated here.

[0111] It is understandable that the following will be discussed in conjunction with Embodiment 1, Embodiment 2, and... Figure 7 The above-mentioned preset vector thresholds will be explained.

[0112] Please refer to the following: Figure 7 First, based on the project requirements, a list of earphone status relationships that need to be determined for wireless earphones can be compiled (S701).

[0113] For example, when wireless headphones are used in a first type of housing (e.g., housing 600), their headphone status is generally: open and inserted into the housing, closed and inserted into the housing, out of the housing, out of the housing with interference. As another example, when wireless headphones are used in a second type of housing (e.g., housing 800), their headphone status is generally: open and inserted into the housing (lower cover), open and inserted into the housing (upper cover), closed and inserted into the housing, out of the housing, out of the housing with interference.

[0114] For example, in one embodiment, the earphone state can be determined by whether the housing is provided with a third magnet for attaching the earphone body to the top cover. For instance, when the housing is not provided with a third magnet for attaching the earphone body to the top cover, it indicates that the housing is of the first type shown in Embodiment 1, and the wireless earphones include at least the four earphone states described above. When the housing is provided with a third magnet for attaching the earphone body to the top cover, it indicates that the housing is of the second type shown in Embodiment 2, and the wireless earphones include at least the five earphone states described above.

[0115] Of course, it is understandable that with further technological development in the future, more relationships may be needed, such as the charging case being on a wireless charging dock, or the earphones being on a wireless charging dock (the earphones support wireless charging products), etc. Therefore, for the above-mentioned integrated products, the states that need to be detected are more diverse, depending on the form of the integrated body. For example, when the earphones are integrated with a necklace, it is necessary to detect whether the earphones are on the necklace; when the earphones are integrated with a helmet, it is necessary to detect whether the earphones are inside the helmet; when the earphones are integrated with glasses, it is necessary to detect whether the earphones are on the glasses, etc. In the embodiments of this application, for the sake of simplicity, the above-mentioned earphone states are not limited, and the above four or five common earphone states are mainly used as examples for explanation.

[0116] Next, based on the headphone state relationship determined above, different magnets are preset so that different magnetic fields exist under different headphone state relationships (S702).

[0117] It is understandable that the required number of magnets varies depending on the complexity of the project. For example, when distinguishing between the four earphone states (open case and in case, closed case and in case, out of case, external interference), two magnets can be placed on the top and bottom cases respectively (see Example 1). When distinguishing between the five earphone states (open case and in case on the bottom case, open case and in case on the top case, closed case and in case, out of case, out of case interference), at least two magnets can also be set. Of course, to enhance the adsorption experience, the number of magnets can be adjusted (e.g., increased) appropriately (see Example 2). As another example, when it is necessary to check the charging dock's position, the charging dock can also be equipped with corresponding magnets as needed, for example, the minimum magnet requirement is three or more, which can be selected according to the number of different charging docks. As yet another example, fusion products need to add different magnets to different fusion bodies for N fusion bodies (differences in position, shape, etc. will result in different magnetic fields) to meet the detection of multiple fusion bodies. It is understood that other magnetic fields that do not meet the above state conditions can be considered as external interference.

[0118] Third, perform magnetic simulation to obtain the magnetic field vector (S703) under different magnetic fields.

[0119] For example, in Embodiment 1, a first magnet 605a and a second magnet 604a can be preset, and magnetic simulation can be performed to obtain the magnetic field vectors under different magnetic fields (e.g., the wireless earphones are in the closed case state, the open case state, and the out case state). As another example, in Embodiment 2, a first magnet 805a, a second magnet 804a, and a third magnet 807a can be preset, and magnetic simulation can be performed to obtain the magnetic field vectors under different magnetic fields (e.g., the wireless earphones are in the closed case state, the open case state attached to the lower cover state, the open case state attached to the upper cover state, and the out case state).

[0120] Finally, based on the differences in the simulated magnetic field under each state, different vector thresholds (S704) are selected.

[0121] For example, based on the above description, the relationship between various headphone states and vector thresholds can be obtained as shown in Table 1.

[0122] Table 1. Simulated magnetic field values ​​and threshold relationships under various conditions.

[0123]

[0124]

[0125] For another example, please refer to Table 2 below, which shows the magnetic field simulation under various states when the wireless earphone is applied to the second type of housing (e.g., housing 800 in embodiment 2), and the selected or set vector threshold values ​​for each state. Parameter 'a' refers to the magnetic field vector sensed by the earphone body 700 when only a single magnet is set (e.g., only the first magnet 805a is set, without the second magnet 804a and the third magnet 807a).

[0126] Of course, in this embodiment, the size, shape, material, and other parameters of the magnets included in the box 800 are not limited. For example, the size, shape, and material parameters of the first magnet 805a, the second magnet 804a, and the third magnet 807a of the box 800 can be set to be consistent or adjusted according to the actual situation.

[0127] Table 2. Simulated magnetic field values ​​and vector threshold relationships under various headphone states in Example 2.

[0128] state Magnetic field (vector) Simulation theoretical value Vector threshold Close the lid and put it in the box strongest 2.24 a millitalas (mT) Vector sum >2a mT The cap adheres to the top cover when opened. Strong 1.4a mT 1.2a mT < vector sum < 2a mT The cap is opened and the lower cover is adsorbed. weak a mT 0.5a mT < vector sum < 1.2a mT Out of box Weakest <a mT, approximately 0 Vector sum <0.5a mT

[0129] As can be understood from Table 2, the earphone body 700a detects the magnetic field vector sum under different states using a magnetic sensor and transmits it to the processor. The processor then determines the state of the earphone body 700a based on the received magnetic field vector sum and a preset vector threshold. For example, when the processor determines that the vector sum meets the first vector threshold (e.g., vector sum > 2a mT), it determines that the earphone body 700a is in the closed case-placed state. As another example, when the processor determines that the vector sum meets the second vector threshold (e.g., 1.2a mT < vector sum < 2a mT), it determines that the earphone body 700a is in the open case-attached state. As another example, when the processor determines that the vector sum meets the third vector threshold (e.g., 0.5a mT < vector sum < 1.2a mT), it determines that the earphone body 700a is in the open case-attached state. As yet another example, when the processor determines that the vector sum meets the fourth vector threshold (e.g., vector sum < 0.5a mT), it determines that the earphone body 700a is in the case-out state.

[0130] It is understood that in the above simulation process, the vector threshold is set using the vector sum (i.e., the absolute value of the vector). Of course, in other embodiments, it is not limited to the vector sum; the threshold can also be set based on other parameters, such as vector direction, three-axis projection, three-view projection, or projection onto a specific plane. This is not limited here. It is understood that the greater the difference in vector thresholds, the higher the accuracy of the three-axis Hall sensor used for detection, and the stronger the system stability and product consistency.

[0131] In summary, taking Example 1 as an example, the following explains the detection principle of various position / state information (e.g., three types of position / state information) of the earphone body 500a in cooperation with the magnetic sensor 501 and the processor 502. In Example 1, the magnetic sensor 501 can be used to detect the magnetic field vector around the earphone body 500a. The processor 502 can be used to respond to the magnetic field vector transmitted by the magnetic sensor 501, compare the magnetic field vector with a preset vector threshold, and thus determine the state of the earphone body 500a.

[0132] Based on the aforementioned Figure 2- Figure 4 , Figures 5a-5f , Figures 6a-6e , Figure 7 The following describes a method for detecting the location / status information of a wireless earphone provided in this application, illustrated in some embodiments.

[0133] See Figure 8 , Figure 8 A flowchart illustrating a method for detecting the location / status information of a wireless earphone according to an embodiment of this application is shown. This method can be applied to Figure 2- Figure 3 , Figures 5a-5f , Figures 6a-6eThe wireless earphone shown is an example of a wireless earphone body 500a. For instance, the earphone body 500a may include a magnetic sensor 501 and a processor 502. Of course, the earphone body 500a may also include other components. For example, the earphone body 500a could be... Figure 3 The earphone body 300 is shown. (As shown) Figure 8 As shown, the method may include:

[0134] S801, the earphone body detects the magnetic field vector around the earphone body.

[0135] For example, referring to Embodiment 1, the magnetic field vector around the earphone body 500a can be detected by the magnetic sensor 501 in the earphone body 500a. Also, referring to Embodiment 2, the magnetic field vector around the earphone body can be detected by the magnetic sensor in the earphone body 700a.

[0136] S802, the earphone body determines the position / state information of the earphone body based on the detected magnetic field vector and the preset vector threshold.

[0137] For example, S801 can be executed by the magnetic sensor in the earphone body, and S802 can be executed by the processor in the earphone body.

[0138] It is understood that, in the embodiments of this application, the specific method for detecting the position / state information of the earphone body by cooperating with the magnetic sensor and the processor can be referred to the above embodiments 1 and 2. Figure 7 A detailed introduction is not required here.

[0139] It is understood that the housings shown in the above embodiments are all earphone housings. Of course, the type of housing is not limited in the embodiments of this application. For example, the housing can also be other mechanisms that can be used to store wireless earphones, thus, the housing and wireless earphones can constitute various types of integrated products.

[0140] Among them, converged products refer to wireless earphones that can be used in various forms such as portable TWS earphones, health and sports easy-to-store watches, audio glasses (with functions such as quick shooting, video recording, external sound playback, and virtual 3D), stylish smart necklaces, bracelets, wristbands, rings, power banks, adapters, handbags, suitcases, head-mounted devices, ties, mobile phones, water cups, mice, pens, notebooks, rackets, balls, and bicycles. For example, wireless earphones and watches can form a Bluetooth calling watch, wireless earphones and glasses can form audio glasses, wireless earphones and necklaces can form a smart necklace, and so on. All of the above products include a housing or carrier (hereinafter referred to as the carrier) for storing the wireless earphones.

[0141] It is understandable that for fusion products with multiple components, the shape of the carrier can be recognized. Furthermore, this embodiment, by setting a three-axis Hall sensor, can read the magnitude of the magnetic field in x, y, and z directions, thus satisfying the state recognition of various products (i.e., second-level recognition). In other words, this fusion product can generate second-level recognition based on the recognition results of different shapes. For example, when the carrier is recognized as a necklace, after Bluetooth pairing, it switches to the smart necklace function, with two states recognized at the second level (on the chain, off the chain). As another example, when the carrier is recognized as an earphone case, after Bluetooth connection and pairing, it switches to the TWS earphone function, with three states recognized at the second level (earphone out of case, earphone in case with lid closed, earphone in case with lid open). As yet another example, when the carrier is recognized as a watch, after Bluetooth connection and pairing, it switches to the smart watch storage function, with four states recognized at the second level (earphone out of case, earphone in case with lid closed, earphone in case with lid on top, earphone in case with lid on bottom). Of course, watches and the like may also have other different state combinations, which are not limited here. It is understandable that the above-mentioned morphological recognition of the carrier can also be an alternating magnetic field recognition. For example, when the carrier's magnetic field senses the device matching, the carrier modulates the magnetic field vector through an electrical signal to complete magnetic vector communication and achieve device ID recognition.

[0142] In summary, this application has at least the following beneficial effects:

[0143] (1) The multi-position / state information detection method in this application is simple and easy to implement. It uses at least one magnet and at least one magnetic sensor (e.g., a triaxial Hall sensor). By reading the magnitude of the magnetic field in the x, y, and z axes through the magnetic sensor, it can not only be applied to the detection of at least three positions / state information (e.g., earphones out of the case, earphones in the case with the lid closed, earphones in the case with the lid open) in current TWS earphones, but also has the potential for mass production for the expansion of multiple states, achieving multiple state detection in one device with strong scalability. In addition, by combining it with the current electrical and wireless communication interaction mechanisms (e.g., power on / off, battery level, binaural interaction, left / right ear recognition, etc.), more reliable and diversified state detection can be achieved.

[0144] (2) This application, by placing a three-axis Hall sensor at the central axis of the earphone body, can accurately detect multiple position / state information without distinguishing the earphone's orientation or left / right ear position. This overcomes the shortcomings of existing technologies that can only detect in a single direction and only detect earphones entering and leaving the case, achieving 360-degree rotation detection without blind spots. Furthermore, by setting the aforementioned three-axis Hall sensor, this application has strong anti-interference capabilities, allowing for harsher magnetic field environments, while the product can utilize these environments to achieve a better user experience.

[0145] (3) The wireless earphone in this application is adaptable to TWS earphone form factors, and is also applicable to existing and unrealized integrated products in the industry, such as earphones and watches, earphones and necklaces, and earphone cases and glasses. In addition, multi-level magnetic environment detection can be achieved for products of different forms. Furthermore, by cooperating with the magnets in the case, the detection can be made more accurate by optimizing the magnetization direction of the magnets (for example, making the magnetization directions of the two magnets the same).

[0146] (4) The wireless earphones in this application can also be applied to TWS earphones of special shapes or other integrated products, such as cylindrical, quasi-cylindrical (bullet-shaped) earphones that can rotate freely in the housing cavity. In addition, by cooperating with the magnets in the housing, the magnetization direction of the magnets can be optimized to make the detection more accurate.

[0147] It should be understood that the various embodiments of this application can be combined arbitrarily, for example, they can be used individually or in combination with each other to achieve different technical effects, and there is no limitation thereto.

[0148] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
