Description

Technical Field

[0001] The present application relates to the technical field of wireless earphones, and more specifically, to a wireless earphone, a method for detecting its state, an earphone kit, and a storage medium. Background Art

[0002] With the development of technology, wireless earphones have been more and more widely used due to their convenient portability and other characteristics. Since wireless earphones completely eliminate the trouble of wires, they are more favored by users for their more free use. For example, the left and right earbuds of true wireless stereo (TWS) earphones are not connected by wires, and the left and right ears can be connected to a smart terminal device (such as a smartphone) at the same time, or can be used independently, realizing single-ear or dual-ear wearing. In addition, TWS earphones usually come with an earphone charging case, which integrates a mobile power supply. When the TWS earphones are placed in it, the TWS earphones can also be charged.

[0003] Currently, for the state detection of wireless earphones relative to the earphone charging case, a Hall switch is mainly set on the earphone body of the wireless earphone, and a magnet is set on the lid of the earphone charging case. By detecting the high and low levels output by the Hall switch, the position state of the wireless earphone relative to the earphone charging case is determined. For example, when the wireless earphone is inside the earphone charging case and the lid is closed, the magnet on the lid is close to the Hall switch of the wireless earphone, and the Hall switch outputs a high level; when the lid of the earphone charging case is opened, the magnet is far from the Hall switch of the wireless earphone, and the Hall switch outputs a low level.

[0004] However, when the wireless earphone is outside the earphone charging case, but a magnetic object approaches the wireless earphone, the Hall switch of the wireless earphone outputs a high level, and the wireless earphone is misdetected as being in the position state where it is inside the earphone charging case and the lid is closed, resulting in a reduction in the accuracy of the state detection of the wireless earphone. Summary of the Invention

[0005] The present application provides a wireless earphone, a method for detecting its state, an earphone kit, and a storage medium.

[0009] In a fourth aspect, an embodiment of the present application provides a wireless earphone, which includes an earphone body, a sensor group disposed on the earphone body, and a control module; the sensor group includes a transmitter and a receiver.

Therefore, the wireless earphones and the state detection method provided by the embodiments of the present application can detect the position state of the wireless earphones based on the intensity of the reflected signal formed after the detection signal sent by the sensor group is reflected by an obstacle, and do not rely on the traditional magnetic field intensity to detect the position state of the wireless earphones. Therefore, the state detection process of the wireless earphones will not be interfered by an external magnetic field, and the accuracy of the state detection of the wireless earphones can be improved.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0040] Please refer to Figure 1 , the embodiment of the present application provides an earphone kit 10, and the earphone kit 10 includes a wireless earphone 20 and an earphone charging case 30. The wireless earphone 20 is suitable for being charged by the earphone charging case 30, and the earphone charging case 30 can provide electric energy for the wireless earphone 20.

[0041] In this embodiment, please refer to Figure 2, the wireless earphone 20 includes an earphone body 21, a sensor group 22, and a control module 23. The sensor group 22 and the control module 23 are both disposed in the earphone body 21, and the sensor group 22 is electrically connected to the control module 23.

[0042] In some embodiments, the earphone body 21 may include a housing 211 and an audio component 212. One end of the housing 211 may be provided with an ear insertion surface 2111, and the audio component 212 may be disposed inside the housing 211 near the ear insertion surface 2111. The housing 211 can provide mechanical protection for the audio component 212. Among them, the ear insertion surface 2111 may be a surface of the earphone body 21 facing the ear canal when the wireless earphone 20 is worn.

[0043] In some embodiments, the audio component 212 may be electrically connected to the control module 23, and the audio component 212 may be configured to record or play audio under the control of the control module 23.

[0044] In some embodiments, the audio component 212 may include a wireless connection device and a sound-emitting device. The wireless connection device may be electrically connected to the sound-emitting device, and both the wireless connection device and the sound-emitting device may be electrically connected to the control module 23. The wireless connection device may be used to establish a communication connection with a playback terminal. The wireless connection device may be a Bluetooth connection device or a Wireless Local Area Network (WLAN) connection device, as long as it can achieve a wireless connection with the playback terminal. The sound-emitting device may include a microphone, a speaker, etc.

[0045] In this embodiment, the sensor group 22 is configured to send a detection signal X to the outside of the earphone body 21 and is used to receive a reflected signal Y formed after the detection signal X is reflected by an obstacle B, allowing the control module 23 to determine the position state of the wireless earphone 20 relative to the earphone charging case 30 according to the received reflected signal Y.

[0046] In some embodiments, the sensor group 22 may be disposed on one side of the housing 211 facing the ear insertion surface 2111 or on the surface of the ear insertion surface 2111. Further, the sensor group 22 may include a transmitter 221 and a receiver 222. The transmitter 221 and the receiver 222 may be integrally provided or separately spaced, which is not limited herein and may be specifically set according to actual requirements.

[0047] In some embodiments, the type of the sensor group 22 can be a photosensitive sensor, a microwave sensor, a sound-sensitive sensor, or the like. As an example, the sensor group 22 can be an infrared light sensor. Among them, the transmitter 221 can be an infrared light transmitter, and the receiver 222 can be an infrared light receiver. Since the wavelength of infrared light is relatively long, the infrared light sensor has strong anti-interference ability. Therefore, determining the current state of the wireless earphone 20 according to the intensity of the received infrared light can improve the accuracy of the state detection of the wireless earphone 20.

[0048] Please refer to Figure 3 , in some embodiments, the sensor group 22 can be one or more. For example, in some embodiments, the sensor group 22 is multiple. There can be multiple transmitters 221 and multiple receivers 222 in the multiple sensor groups 22. For example, the multiple transmitters 221 can include a first transmitter 2231 and a second transmitter 2241, and the multiple receivers 222 can include a first receiver 2232 and a second receiver 2242. For example, the sensor group 22 can be two. The two sensor groups 22 can include a first sensor group 223 and a second sensor group 224. The first sensor group 223 and the second sensor group 224 can be arranged at intervals on the earphone body 21. The first sensor group 223 can include the above-mentioned first transmitter 2231 and the first receiver 2232, and the second sensor group 224 can include the above-mentioned second transmitter 2241 and the second receiver 2242. Correspondingly, in the two sensor groups 22, the detection signal X can include a first detection signal X1 and a second detection signal X2, and the reflection signal Y can include a first reflection signal Y1 and a second reflection signal Y2. The first transmitter 2231 can be configured to send the first detection signal X1 to the outside of the earphone body 21, and the second transmitter 2241 can be configured to send the second detection signal X2 to the outside of the earphone body 21. The first receiver 2232 can be used to receive the first reflection signal Y1 formed after the first detection signal X1 is reflected by an obstacle, and the second receiver 2242 can be used to receive the second reflection signal Y2 formed after the second detection signal X2 is reflected by an obstacle, which allows the control module 23 to determine the position state of the wireless earphone 20 relative to the earphone charging case 30 according to the received first reflection signal Y1 and the second reflection signal Y2. By respectively arranging the first sensor group 223 and the second sensor group 224 on the earphone body 21, the position states of two different positions on the wireless earphone 20 relative to the earphone charging case 30 can be obtained simultaneously, which can further improve the accuracy of the state detection of the wireless earphone 20.

[0049] In some embodiments, the first sensor group 223 and the second sensor group 224 may be disposed at intervals on one side of the inner housing 211 facing the ear-inward surface 2111. Signal transmission holes may be formed at positions corresponding to the first sensor group 223 and the second sensor group 224 on the ear-inward surface 2111 respectively, and the signal transmission holes may be used to provide a signal transmission channel. The first sensor group 223 and the second sensor group 224 may also be disposed at intervals on the ear-inward surface 2111, which is not limited herein and may be specifically set according to actual requirements.

[0050] In this embodiment, the control module 23 is configured to determine the current state of the wireless earphone 20 according to the intensity of the reflected signal Y and a preset intensity threshold range. Among them, the current state of the wireless earphone 20 includes a plurality of different position states of the wireless earphone 20 relative to the earphone charging case 30. For example, the current state of the wireless earphone 20 may include the in-case state or the worn state of the wireless earphone 20; the intensity threshold range includes a plurality of threshold ranges with non-overlapping ranges. The control module 23 is configured to determine the current state of the wireless earphone 20 according to the relationship between the intensity of the reflected signal Y and the plurality of threshold ranges, and different position states of the wireless earphone 20 can be determined according to different threshold ranges in which the intensity of the reflected signal Y received by the receiver 222 is located, improving the accuracy of the state detection of the wireless earphone 20.

[0051] Among them, the plurality of different position states may include two different position states or more than two different position states. For example, the plurality of different position states may include a first state in which the wireless earphone 20 is located in the earphone charging case 30 and the earphone charging case 30 is closed (the wireless earphone is in the case and the earphone charging case is in the closed-lid state), and a second state in which the wireless earphone 20 is located in the human ear (the wireless earphone is in the worn state). The plurality of different position states may also include a first state in which the wireless earphone 20 is located in the earphone charging case 30 and the earphone charging case 30 is closed (the wireless earphone is in the case and the earphone charging case is in the closed-lid state), a second state in which the wireless earphone 20 is located in the human ear (the wireless earphone is in the worn state), a third state in which the wireless earphone 20 is located in the earphone charging case 30 and the earphone charging case 30 is not closed (the wireless earphone is in the case and the earphone charging case is in the open-lid state), and a fourth state in which the wireless earphone 20 is located outside the earphone charging case 30 and not in the human ear (the wireless earphone is outside the case and not in the worn state).

[0052] Understandably, when the wireless earphones 20 are respectively in the above four states, the detection signal X transmitted by the transmitter 221 can be basically completely reflected by the earphone charging case 30, basically completely reflected by the human ear, not reflected, or partially reflected by the earphone charging case 30. The intensity ranges of the reflected signal Y that the receiver 222 can receive are all different. Four different threshold ranges can be set correspondingly according to the intensity of the reflected signal Y. Therefore, the current state of the wireless earphones 20 can be determined according to the threshold range in which the intensity of the reflected signal Y received by the receiver 222 is located.

[0053] In some embodiments, the control module 23 may include a microcontroller unit (MCU) and a main control circuit. The MCU and the sensor group 22 may be electrically connected through the main control circuit. The MCU may be configured to control the transmitter 221 to transmit the detection signal X and receive the reflected signal Y, and determine the current state of the wireless earphones 20 according to the intensity of the reflected signal Y received by the receiver 222.

[0054] In some embodiments, in order to improve the accuracy of the state detection of the wireless earphones 20, the control module 23 may be configured to determine the current state of the wireless earphones 20 according to the first intensity of the first reflected signal Y1, the second intensity of the second reflected signal Y2, and the intensity threshold range. Therefore, the above-mentioned wireless earphones 20 can determine the position state of the wireless earphones 20 relative to the earphone charging case 30 according to the intensities of multiple reflected signals Y, which can improve the accuracy of the state detection of the wireless earphones 20.

[0055] In some embodiments, the wireless earphones 20 may further include a charging module 24. The charging module 24 may be disposed on the earphone body 21 and electrically connected to the control module 23. The charging module 24 can provide an electrical connection for the wireless earphones 20 when the wireless earphones 20 are charging.

[0056] In some embodiments, the charging module 24 may be disposed at one end of the housing 211 away from the ear insertion surface 2111. The charging module 24 and the control module 23 may be electrically connected through the main control circuit. As an example, the charging module 24 may be a wired charging module, which may include a battery and charging pins. The charging pins and the battery may be electrically connected. The charging pins may be used to conduct the power supply circuit to charge the battery when the wireless earphones 20 are charging. Among them, the charging pins may include Pogo pin connectors, spring sheet connectors, etc. As another example, the charging module 24 may be a wireless charging module, which may include a battery and an electromagnetic coil. The electromagnetic coil may be configured to generate an induced electromotive force to charge the battery when it is in a changing induction magnetic field. The specific setting method of the charging module 24 is not limited herein and may be specifically set according to actual needs.

[0057] In some embodiments, the control module 23 may further be configured to determine the working state of the wireless earphone 20 according to the level state of the charging module 24, and the working state may be used to characterize the charging state and the non-charging state of the wireless earphone.

[0058] As an example, the pins of the charging module 24 may include Pogo pin connectors. When the wireless earphone 20 is connected to the earphone charging case 30, that is, when the earphone charging case 30 charges the wireless earphone 20, the earphone charging case 30 may apply a charging voltage to the Pogo pin connectors, and a first level (high level) may be generated between the Pogo pin connectors; and when the wireless earphone 20 is disconnected from the earphone charging case 30, that is, when the earphone charging case 30 does not charge the wireless earphone 20, the earphone charging case 30 fails to apply a voltage to the Pogo pin connectors, and a second level (low level) may be generated between the Pogo pin connectors. When determining the working state of the wireless earphone 20, the control module 23 may detect the level state of the Pogo pin connectors. When the control module 23 detects that the level state of the Pogo pin connectors is the first level, it may be determined that the wireless earphone 20 is in a charging state; when the control module 23 detects that the level state of the Pogo pin connectors is the second level, it may be determined that the wireless earphone 20 is in a non-charging state.

[0059] In some embodiments, in order to further improve the accuracy of the state detection of the wireless earphone 20, the control module 23 may further be configured to determine whether the earphone charging case 30 is closed when the wireless earphone 20 is received in the earphone charging case 30 according to the intensity of the reflection signal Y, the intensity threshold range, and the working state of the wireless earphone 20. Therefore, the wireless earphone 20 provided by the embodiment of the present application can determine the position state of the wireless earphone 20 relative to the earphone charging case 30 according to the working state of the wireless earphone 20, and at the same time determine whether the earphone charging case 30 is closed when the wireless earphone 20 is received in the earphone charging case 30 according to the intensity of the reflection signal Y, which can further improve the accuracy of the state detection of the wireless earphone 20.

[0060] Please refer to Figure 4 , in this embodiment, the earphone charging case 30 is provided with a storage cavity 31 for storing the wireless earphone 20. When the wireless earphone 20 is received in the storage cavity 31, the earphone charging case 30 can provide mechanical protection for the wireless earphone 20.

[0061] In some embodiments, the earphone charging case 30 may include a case body 32 and a reflector 33. The storage cavity 31 may be provided in the case body 32, and the reflector 33 may be provided on the surface of the case body 32 facing the storage cavity 31. When the wireless earphone 20 is accommodated in the storage cavity 31, the reflector 33 may be disposed opposite to the transmitter 221 to reflect the detection signal X, which can improve the reflection intensity of the detection signal X emitted by the transmitter 221 by the reflector 33.

[0062] In some embodiments, the case body 32 may include a lid 321 and a housing 322, and the lid 321 and the housing 322 may be movably connected. The housing 322 may be provided with a first accommodation cavity 311, and the lid 321 may be provided with a second accommodation cavity 312. The housing 322 may include an end face 3221 adapted to be covered by the lid 321; when the lid 321 is covered on the end face 3221, the first accommodation cavity 311 and the second accommodation cavity 312 may communicate with each other to jointly define the storage cavity 31. When the wireless earphone 20 is accommodated in the storage cavity 31 and the lid 321 is covered on the end face 3221, the wireless earphone 20 can be prevented from being damaged by dust erosion, and the service life of the wireless earphone 20 can be extended.

[0063] In some embodiments, the case body 32 may further include a power supply module 34 adapted to be electrically connected to the charging module 24 of the earphone body 21, and the power supply module 34 may be provided in the housing 322. The control module 23 may further be configured to determine the current state of the wireless earphone 20 according to the level state of the charging module 24 and the reflection signal Y when the power supply module 34 is electrically connected to the charging module 24. The position state of the wireless earphone 20 relative to the earphone charging case 30 can be determined according to the working state of the wireless earphone 20. At the same time, according to the intensity of the reflection signal Y, it can be determined whether the earphone charging case 30 is closed when the wireless earphone 20 is accommodated in the earphone charging case 30, which can further improve the accuracy of the state detection of the wireless earphone 20. Among them, the power supply module 34 may be a wired power supply module or a wireless power supply module. The wired power supply module may be cooperatively connected with a wired charging module, and the wireless power supply module may be cooperatively connected with a wireless charging module. The specific setting manner of the power supply module 34 is not limited herein and may be specifically set according to actual requirements.

[0064] In some embodiments, the reflector 33 may include a metal piece, a metal thin film, a metal compound thin film, a dielectric thin film, etc. that have a high reflection intensity for the detection signal X. As an example, the detection signal X may be an infrared light signal, the reflector 33 may be a copper metal, or a silver (Ag) thin film, or a zinc sulfide (ZnS) / Ag / ZnS thin film, or a titanium dioxide (TiO2) / Ag / TiO2 thin film, etc. In addition, when the detection signal X is an infrared light signal, the reflector 33 may also be a reflection curved surface that has a high reflection intensity for the infrared light signal, and / or a reflection surface with an optical design. The reflector 33 may also be a structure with a reflection curved surface formed by attaching a metal piece, a metal thin film, a metal compound thin film, or a dielectric thin film with a high reflection intensity to the inner curved surface of the headphone charging case 30.

[0065] In an application scenario, the sensor group 22 may be an infrared light sensor. The emitter 221 of the infrared light sensor may be an infrared light emitter, and the receiver 224 of the infrared light sensor may be an infrared light receiver. The infrared light emitter and the infrared light receiver may be arranged in parallel. It can be understood that when using the infrared light sensor to detect the light intensity, the relationship between the light intensity detected by the infrared light sensor and the resistance value of the infrared light sensor may be as Figure 5 shown.

[0066] When the infrared light X3 emitted by the infrared light emitter is reflected by the reflector 33, as Figure 6 shown, the infrared light receiver can basically receive all the reflected infrared light Y3. The light intensity of the reflected infrared light Y3 received by the infrared light receiver is the strongest. The light intensity range of the reflected infrared light Y3 received by the infrared light receiver can be defined as the first threshold range. For example, the first threshold range may be (c, +∞). When the infrared light X3 emitted by the infrared light emitter is basically all reflected by the obstacle B1, as Figure 7 shown, the infrared light receiver can receive most of the reflected infrared light Y3. The light intensity range of the reflected infrared light Y3 received by the infrared light receiver can be defined as the second threshold range. For example, the second threshold range may be (b, c]. When the infrared light X3 emitted by the infrared light emitter is partially reflected by the obstacle B2, as Figure 8 shown, the infrared light receiver can receive part of the reflected infrared light Y3. The light intensity range of the reflected infrared light Y3 received by the infrared light receiver can be defined as the third threshold range. For example, the third threshold range may be (a, b]. When the infrared light X3 emitted by the infrared light emitter is not reflected by the obstacle, as Figure 9As shown, the infrared light receiver does not receive the reflected infrared light Y3. The light intensity range of the reflected infrared light Y3 received by the infrared light receiver can be defined as the fourth threshold range. For example, the fourth threshold range can be (0, a]. Wherein, the reflectivity of the reflector 33 to the infrared light is greater than the reflection intensity of the obstacle B1 to the infrared light. The reflectivity of the obstacle B1 to the infrared light is basically the same as that of the obstacle B2 to the infrared light, and 0 < a < b < c. The obstacle B1 can be a human ear or a part of the structure in the earphone charging case 30 where the reflector 33 is not provided, etc.

[0067] In some embodiments, the reflector 33 can be disposed on the cover body 321 or / and the housing 322. The control module 23 can also be configured to determine the current state of the wireless earphone 20 according to the intensity of the reflected signal Y formed after the detection signal X is reflected by the reflector 33 and the intensity threshold range, which can improve the intensity of the reflected signal Y received by the sensor group 22 and improve the accuracy of the state detection of the wireless earphone 20.

[0068] According to the wireless earphone 20 and the earphone charging case 30 provided in the above embodiments, the present application further provides a plurality of possible embodiments for the wireless earphone 20 and the earphone charging case 30 adapted thereto. In these embodiments, the structure of the wireless earphone 20 can be substantially the same as that of the wireless earphone 20 provided in the above embodiments, and the structure of the earphone charging case 30 can be substantially the same as that of the earphone charging case 30 provided in the above embodiments. The wireless earphone 20 can also include an earphone body 21, a sensor group 22, and a control module 23, which will not be elaborated in this specification. The differences are generally as follows: In different embodiments, the specific installation positions of the sensor group 22 and the reflector 33 may be different, as described below.

[0069] In some embodiments, please refer to Figure 10, the sensor group 22 can be disposed at the first ear insertion position 2112. The first ear insertion position 2112 can be the position on the ear insertion surface 2111 opposite to the end face 3221 when the wireless earphone 20 is received in the receiving cavity 31. The transmitter 221 can be partially located in the first receiving cavity 311. The transmitting end of the transmitter 221 can be opposite to the side of the end face 3221, which means that when the wireless earphone 20 is received in the receiving cavity 31, a part of the structure of the transmitter 221 can be blocked by the housing 322, and another part of the structure of the transmitter 221 can protrude from the end face 3221. When the wireless earphone 20 is received in the receiving cavity 31, the detection signal X transmitted by the transmitter 221 can be reflected by the housing 322 substantially entirely or partially. For example, when the cover 321 of the earphone charging case 30 is covered on the end face 3221, a part of the detection signal X transmitted by the transmitter 221 can be reflected by the housing 322, and another part of the detection signal X transmitted by the transmitter 221 can be reflected by the cover 321, that is, the detection signal X can be reflected by the earphone charging case 30 substantially entirely. When the cover 321 of the earphone charging case 30 is not covered on the end face 3221, the detection signal X transmitted by the transmitter 221 can be partially reflected by the housing 322. Therefore, according to the different intensities of the reflected signal Y received by the receiver 222, the different position states of the cover 321 of the earphone charging case 30 relative to the wireless earphone 20 can be determined when the wireless earphone 20 is located in the earphone charging case 30.

[0070] Understandably, when the wireless earphone 20 is worn, the ear insertion surface 2111 faces the ear canal 40 of the human ear. As Figure 11 shown, the detection signal X transmitted by the transmitter 221 can be reflected by the ear canal 40 to form a reflected signal Y, and the receiver 222 can receive the reflected signal Y.

[0071] Furthermore, in this embodiment, the reflector 33 can be disposed at the first cover position 3211 on the cover 321. The first cover position 3211 can be the position on the cover 321 opposite to the infrared light sensor when the wireless earphone 20 is received in the receiving cavity 31 and the cover 321 is covered on the end face 3221. In addition, the reflector 33 can include two parts of structures. One part of the structure of the reflector 33 can be disposed in the cover 321, and another part of the structure of the reflector 33 can be disposed in the housing 322. When the cover 321 is covered on the end face 3221, the parts of the structure of the reflector 33 respectively disposed on the cover 321 and the housing 322 can be connected to each other so that the reflector 33 can reflect the detection signal X entirely.

[0072] In this embodiment, according to the setting positions of the above-mentioned sensor group 22 and the reflector 33, the control module 23 can be configured to determine the current state of the wireless earphone 20 based on the intensity of the reflected infrared light Y3 formed after the infrared light X3 sent by the infrared light sensor is reflected by an obstacle and the threshold range, including: when the light intensity of the reflected infrared light Y3 received by the infrared light sensor falls within the first threshold range (indicating that the infrared light X3 sent by the infrared light sensor can be reflected by the reflector 33), it is determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 covers the end face 3221, that is, it can be determined that the wireless earphone 20 is in the first state; when the light intensity of the reflected infrared light Y3 falls within the second threshold range (indicating that the infrared light X3 sent by the infrared light sensor can be almost completely reflected by the obstacle), it is determined that the wireless earphone 20 is located in the human ear, that is, it can be determined that the wireless earphone 20 is in the second state; when the light intensity of the reflected infrared light Y3 falls within the third threshold range (indicating that the infrared light X3 sent by the infrared light sensor can be partially reflected by the obstacle), it is determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 does not cover the end face 3221, that is, it can be determined that the wireless earphone 20 is in the third state; when the light intensity of the reflected infrared light Y3 falls within the fourth threshold range (indicating that the infrared light X3 sent by the infrared light sensor cannot be reflected by the obstacle), it is determined that the wireless earphone 20 is outside the earphone charging case 30 and not in the human ear, that is, it can be determined that the wireless earphone 20 is in the fourth state. The corresponding relationship between the threshold range in which the intensity of the reflected infrared light Y3 received by the infrared light sensor is located and the state of the wireless earphone 20 can be as shown in Table 1, and this table can be preset in the control module 23. When the control module 23 determines the state of the wireless earphone 20 based on the intensity of the received reflected infrared light Y3, the state of the wireless earphone 20 can be determined by looking up the table.

[0074]

[0075] In some embodiments, please refer to Figure 12 , the sensor group 22 can be two, and the two sensor groups 22 can include a first sensor group 223 and a second sensor group 224. The first sensor group 223 can be a first infrared light sensor 223, the second sensor group 224 can be a second infrared light sensor 224, and the first infrared light sensor 223 can be disposed at a first ear insertion position 2112. The second infrared light sensor 224 can be disposed at a second ear insertion position 2113. When the wireless earphone 20 is received in the receiving cavity 31 and the cover 321 covers the end face 3221, the second ear insertion position 2113 can be the position on the ear insertion surface 2111 located in the second receiving cavity 312.

[0076] Further, in this embodiment, the reflector 33 may be disposed at the second cover position 3212 on the cover body 321. The second cover position 3212 may be the position on the cover body 321 that is opposite to the second infrared light sensor 224 when the wireless earphone 20 is received in the receiving cavity 31 and the cover body 321 covers the end face 3221, and the reflector 33 is opposite to the second infrared light sensor 224. In addition, the reflector 33 may also be disposed at the first cover position 3211. When the wireless earphone 20 is received in the receiving cavity 31 and the cover body 321 covers the end face 3221, the reflector 33 may be opposite to the first infrared light sensor 223. The reflector 33 may also be composed of two parts. One part of the reflector 33 may be disposed inside the cover body 321, and the other part of the reflector 33 may be disposed inside the housing 322. When the wireless earphone 20 is received in the receiving cavity 31 and the cover body 321 covers the end face 3221, the partial structures of the reflector 33 respectively disposed on the cover body 321 and the housing 322 may be connected, and the reflector 33 may be opposite to the first infrared light sensor 223.

[0077] In this embodiment, according to the installation positions of the above-mentioned sensor group 22 and the reflector 33, the control module 23 can be configured to determine the state of the wireless earphone 20 based on the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223, the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224, and the threshold range, including: when the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223 falls within the second threshold range (indicating that the infrared light X3 emitted by the first infrared light sensor 223 can be completely reflected by the obstacle), and the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224 falls within the first threshold range (indicating that the infrared light X3 emitted by the second infrared light sensor 224 can be reflected by the reflector 33), it can be determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 is covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the first state; when the light intensities of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second infrared light sensor 224 both fall within the second threshold range (indicating that the infrared lights X3 emitted by the first infrared light sensor 223 and the second infrared light sensor 224 can both be completely reflected by the obstacle), it can be determined that the wireless earphone 20 is located in the human ear, that is, it can be determined that the wireless earphone 20 is in the second state; when the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223 falls within the third threshold range (indicating that the infrared light X3 emitted by the first infrared light sensor 223 can be partially reflected by the obstacle), and the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224 falls within the fourth threshold range (indicating that the infrared light X3 emitted by the second infrared light sensor 224 is not reflected by the obstacle), it can be determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 is not covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the third state; when the light intensities of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second infrared light sensor 224 both fall within the fourth threshold range (indicating that the infrared lights emitted by the first infrared light sensor 223 and the second infrared light sensor 224 are not reflected by the obstacle), it can be determined that the wireless earphone 20 is not outside the earphone charging case 30 and not in the human ear, that is, it can be determined that the wireless earphone 20 is in the fourth state. The corresponding relationship between the threshold ranges where the intensities of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second infrared light sensor 224 are located and the state of the wireless earphone 20 can be as shown in Table 2.

[0078] Table 2

[0079]

[0080] In some embodiments, please refer to Figure 13, the first infrared light sensor 223 may be disposed at the third earplug position 2114 of the earplug surface 2111. The third earplug position 2114 may be the position of the wireless earphone 20 within the accommodation cavity 31 and on the earplug surface 2111 within the first accommodation cavity 311. The second infrared light sensor 224 may be disposed at the second earplug position 2113 of the earplug surface 2111.

[0081] Further, in this embodiment, the reflector 33 may include a first reflector 331 and a second reflector 332. The first reflector 331 may be disposed at the first housing position 3221 on the housing 322. The first housing position 3221 may be the position on the housing 322 opposite to the first infrared light sensor when the wireless earphone 20 is accommodated in the accommodation cavity 31. The second reflector 332 may be disposed at the second cover position 3212 on the cover body 321. When the wireless earphone 20 is accommodated in the accommodation cavity 31 and the cover body 321 is covered on the end surface 3221, the first reflector 331 may be opposite to the first infrared light sensor 223, and the second reflector 332 may be opposite to the second infrared light sensor 224.

[0082] In this embodiment, according to the setting positions of the above-mentioned sensor group 22 and the reflector 33, the control module 23 can be configured to determine the current state of the wireless earphone 20 based on the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223, the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224, and the threshold range, including: when the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223 falls within the first threshold range (indicating that the infrared light X3 emitted by the first infrared light sensor 223 can be reflected by the first reflector 331), and the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224 falls within the first threshold range (indicating that the infrared light X3 emitted by the second infrared light sensor 224 can be reflected by the second reflector 332), it can be determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 is covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the first state; when the light intensity threshold ranges of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second infrared light sensor 224 both fall within the second threshold range (indicating that the infrared lights X3 emitted by the first infrared light sensor 223 and the second infrared light sensor 224 can both be completely reflected by the obstacle), it can be determined that the wireless earphone 20 is located in the human ear, that is, it can be determined that the wireless earphone 20 is in the second state; when the light intensity of the reflected infrared light Y3 received by the first infrared light sensor 223 falls within the first threshold range (indicating that the infrared light X3 emitted by the first infrared light sensor 223 can be reflected by the first reflector 331), and the light intensity of the reflected infrared light Y3 received by the second infrared light sensor 224 falls within the fourth threshold range (indicating that the infrared light X3 emitted by the second infrared light sensor 224 may not be reflected by the obstacle), it can be determined that the wireless earphone 20 is located in the earphone charging case 30 and the cover 321 is not covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the third state; when the light intensities of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second sensor group both fall within the fourth threshold range (indicating that the infrared lights X3 emitted by the first infrared light sensor 223 and the second infrared light sensor 224 may not be reflected by the obstacle), it can be determined that the wireless earphone 20 is outside the earphone charging case 30 and not in the human ear, that is, it can be determined that the wireless earphone is in the fourth state. The corresponding relationship between the threshold range in which the intensities of the reflected infrared light Y3 received by the first infrared light sensor 223 and the second infrared light sensor 224 are located and the state of the wireless earphone 20 can be as shown in Table 3.

[0083] Table 3

[0084]

[0085] In some embodiments, please refer to Figure 14, the sensor group 22 can be disposed at the third ear-in position 2114. The transmitter 221 can be located in the first accommodation cavity 311 and face the inner surface of the housing 322. When the wireless earphone 20 is received in the storage cavity 31, the transmitter 221 can be completely blocked by the housing 322, so that when the wireless earphone 20 is received in the storage cavity 31, the detection signal X transmitted by the transmitter 221 can be completely reflected by the housing 322. The position state of the wireless earphone 20 relative to the earphone charging case 30 can be determined according to the intensity of the reflected signal Y received by the receiver 222 and the intensity threshold. Among them, the position state of the wireless earphone 20 relative to the earphone charging case 30 can include the position state of the wireless earphone 20 inside the earphone charging case 30 and the position state of the wireless earphone 20 outside the earphone charging case 30.

[0086] In some embodiments, please refer to Figure 15 , the sensor group 22 can be disposed at the second ear-in position 2113. When the wireless earphone 20 is received in the storage cavity 31 and the cover 321 covers the end face 3221, the transmitter 221 can be located in the second accommodation cavity 312 and face the surface of the cover 321, indicating that the detection signal X transmitted by the transmitter 221 can be completely reflected by the cover 321. The state of the earphone charging case 30 can be determined according to the intensity of the reflected signal Y received by the receiver 222 and the intensity threshold. Among them, the state of the earphone charging case 30 can include the state where the earphone charging case 30 is closed and the state where the earphone charging case 30 is not closed.

[0087] Further, in this embodiment, the reflecting member 33 can be disposed at the second cover position 3212 on the cover 321.

[0088] In this embodiment, according to the set positions of the above-mentioned sensor group 22 and the reflector 33, the control module 23 can be configured to determine the current state of the wireless earphone 20 based on the intensity of the reflected infrared light Y3 formed after the infrared light X3 sent by the infrared light sensor is reflected by an obstacle and the threshold range, including: when the light intensity of the reflected infrared light Y3 received by the infrared light sensor falls within the first threshold range (indicating that the infrared light X3 sent by the infrared light sensor can be reflected by the reflector 33), it can be determined that the wireless earphone 20 is located inside the earphone charging case 30 and the cover 321 is covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the first state (since only when the infrared light sensor receives the reflected infrared light Y3 reflected by the reflector 33, the light intensity of the reflected light Y3 may fall within the first threshold range, so when the light intensity of the received reflected infrared light Y3 is within the first threshold range, without relying on the working state of the wireless earphone 20, that is, regardless of the charging state of the wireless earphone 20, it can be directly determined that the current state of the wireless earphone 20 is the first state); when the light intensity of the reflected infrared light Y3 received by the infrared light sensor falls within the second threshold range (indicating that the infrared light X3 sent by the infrared light sensor can be completely reflected by the obstacle), and the level state of the charging module 24 is the second level (indicating that the working state of the wireless earphone 20 can be a non-charging state), it can be determined that the wireless earphone 20 is located in the human ear, that is, it can be determined that the wireless earphone 20 is in the second state; when the light intensity of the reflected infrared light Y3 received by the infrared light sensor falls within the fourth threshold range (indicating that the infrared light X3 sent by the infrared light sensor may not be reflected by the obstacle), and the level state of the charging module 24 is the first level (indicating that the working state of the wireless earphone 20 can be a charging state), it can be determined that the wireless earphone 20 is located inside the earphone charging case 30 and the cover 321 is not covered on the end face 3221, that is, it can be determined that the wireless earphone 20 is in the third state; when the light intensity of the reflected infrared light Y3 received by the infrared light sensor falls within the fourth threshold range (indicating that the infrared light X3 sent by the infrared light sensor may not be reflected by the obstacle), and the level state of the charging module 24 is the second level, it can be determined that the wireless earphone 20 is outside the earphone charging case 30 and not in the human ear, that is, it can be determined that the wireless earphone 20 is in the fourth state. The corresponding relationship between the threshold range in which the intensity of the reflected infrared light Y3 received by the infrared light sensor is located and the level state of the charging module 24 and the state of the wireless earphone 20 can be as shown in Table 4.

[0089] Table 4

[0090]

[0091] In some embodiments, the sensor group 22 can be an infrared light sensor. To reduce the influence of the external ambient light of the wireless earphone 20 on the infrared light sensor, for example, if there is an infrared camera in the external environment of the wireless earphone 20 or sunlight shines, the light intensity threshold range can be set to be extremely large to distinguish that the reflected infrared light Y3 received by the infrared light sensor is non-ambient light, which can improve the accuracy of the state detection of the wireless earphone 20. Among them, the light intensity threshold range can also be set to be extremely small to distinguish that the reflected infrared light Y3 received by the infrared light sensor is non-ambient light. The specific setting method of the light intensity threshold range is not limited here and can be specifically set according to actual needs.

[0092] In the elaboration of the above embodiments, the vertical storage method is taken as an example to introduce the wireless earphone 20 and the earphone charging case 30. In other embodiments, the storage method of the wireless earphone 20 can also be a horizontal storage method. For example, please refer to Figure 16 , in some embodiments, the wireless earphone 20 can also be accommodated in the storage cavity 31 along a direction parallel to the end face 3221, that is, the wireless earphone 20 can be horizontally stored in the earphone charging case 30. Among them, the position settings of the sensor group 22 and the reflector 33 can refer to the setting methods in the foregoing embodiments and will not be elaborated here.

[0093] In the wireless earphone 20 and the earphone kit 10 provided by the embodiments of the present application, the wireless earphone 20 includes an earphone body 21, a sensor group 22, and a control module 23. The sensor group 22 is arranged on the earphone body. The sensor group 22 includes a transmitter 221 and a receiver 222. The transmitter 221 is configured to send a detection signal X to the outside of the earphone body 21, and the receiver 222 is used to receive a reflection signal Y formed after the detection signal X is reflected by an obstacle. The control module 23 is arranged on the earphone body 21 and is electrically connected to the sensor group 22. The control module 23 is configured to determine the in-case state or the wearing state of the wireless earphone 20 according to the intensity of the reflection signal Y and a preset intensity threshold range. Therefore, the wireless earphone provided by the embodiments of the present application can detect the position state of the wireless earphone 20 based on the intensity of the reflection signal Y formed after the detection signal X sent by the sensor group 22 is reflected by an obstacle, and does not rely on the traditional magnetic field intensity to detect the position state of the wireless earphone 20. Therefore, the state detection process of the wireless earphone 20 will not be interfered by the external magnetic field, and the accuracy of the state detection of the wireless earphone 20 can be improved.

[0094] Furthermore, the reflection signal Y is formed after the detection signal X is reflected by an obstacle. Since the relative positions of the obstacle and the sensor group 22 are different, the intensities of the formed reflection signals Y are also different. The multiple position states of the wireless earphone 20 can be determined according to the different threshold ranges in which the intensity of the received reflection signal Y is located, further improving the accuracy of the state detection of the wireless earphone 20.

[0095] Please refer to Figure 17 . An embodiment of the present application provides a method for detecting the state of a wireless earphone. The method for detecting the state of the wireless earphone can be applied to a wireless earphone 20 as shown in Figure 1 . The wireless earphone 20 is adapted to be received in a receiving cavity 31 within an earphone charging case 30. The wireless earphone 20 may include an earphone body 21, a sensor group 22, and a control module 23. The sensor group 22 and the control module 23 may both be disposed on the earphone body 21. The sensor group 22 may be electrically connected to the control module 23; the sensor group 22 may include a transmitter and a receiver.

[0096] As shown in Figure 17 , the method for detecting the state of the wireless earphone provided in this embodiment may include the following steps: S110 - S130.

[0097] Step S110: Send a detection signal to the outside of the earphone body.

[0098] In an embodiment of the present application, the transmitter may emit a detection signal, and the control module may control the transmitter to send the detection signal to the outside of the earphone body. Among them, the transmitter may include a photosensitive sensor, a microwave sensor, a sound-sensitive sensor, etc.

[0099] In some embodiments, the transmitter may be a photosensitive sensor. For example, the transmitter may be an infrared light sensor, and the detection signal may be an infrared light signal; the control module may control the infrared light sensor to send an infrared light signal to the outside of the earphone body.

[0100] In some embodiments, the transmitter may be a microwave sensor, and the detection signal may be a microwave signal; the control module may control the microwave sensor to send a microwave signal to the outside of the earphone body.

[0101] In some embodiments, the transmitter may be a sound-sensitive sensor, and the detection signal may be a sound signal; the control module may control the sound-sensitive sensor to send a sound signal to the outside of the earphone body.

[0102] Step S120: Receive a reflected signal.

[0103] In an embodiment of the present application, after the control module controls the transmitter to send a detection signal to the outside of the earphone body, it may control the receiver to receive the reflected signal. Among them, the reflected signal is formed based on the detection signal being reflected by an obstacle. Among them, the receiver may be an optical receiver, a microwave receiver, a sound receiver, etc.

[0104] In some embodiments, the receiver can be an optical receiver. For example, the receiver can be an infrared light receiver, and the control module can control the infrared light receiver to receive a reflected infrared light signal formed after the infrared light is reflected by an obstacle.

[0105] In some embodiments, the receiver can be a microwave receiver, and the control module can control the microwave receiver to receive a reflected microwave signal formed after the microwave signal is reflected by an obstacle.

[0106] In some embodiments, the receiver can be a sound receiver, and the control module can control the sound receiver to receive a reflected sound signal formed after the sound signal is reflected by an obstacle.

[0107] Step S130: Determine the in-case state or wearing state of the wireless earphone according to the intensity of the reflected signal and the relationship between the reflected signal and a plurality of preset threshold ranges.

[0108] In the embodiments of the present application, the control module can include a microcontroller unit (MCU) and a main control circuit. The MCU and the sensor group can be electrically connected through the main control circuit. The MCU can be used to control the transmitter to send a detection signal and receive a reflected signal, and control the receiver to receive the reflected signal.

[0109] After the control module controls the receiver to receive the reflected signal, it can determine the current state of the wireless earphone according to the intensity of the reflected signal received by the receiver and the relationship between the reflected signal and a plurality of preset threshold ranges. For example, the current state of the wireless earphone can include the in-case state or the wearing state of the wireless earphone. Among them, the current state of the earphone includes multiple different position states of the earphone relative to the earphone charging case; the ranges of the multiple threshold ranges do not intersect, and the control module can be configured to determine the current state of the wireless earphone according to the relationship between the intensity of the reflected signal and the multiple threshold ranges. It can be understood that the multiple different position states can include two different position states or more than two different position states. For example, the multiple different position states can include a storage state where the wireless earphone is located in the earphone charging case and the earphone charging case is closed, and a wearing state where the wireless earphone is located in the human ear. The multiple different position states can also include a storage state where the wireless earphone is located in the earphone charging case and the earphone charging case is closed, a wearing state where the wireless earphone is located in the human ear, an external state where the wireless earphone is neither located in the earphone charging case nor in the human ear, and other states other than the storage state and the external state.

[0110] In some embodiments, multiple threshold ranges may include a first range and a second range. The lower limit value of the first range may be greater than the upper limit value of the second range. The first range may be used to characterize the stored state of the wireless earphones, and the second range may be used to characterize the worn state of the wireless earphones. When the control module determines that the intensity of the received reflected signal falls within the first range based on the intensity of the received reflected signal, the control module may determine that the wireless earphones are in the stored state. Or when the control module determines that the intensity of the received reflected signal falls within the second range based on the intensity of the received reflected signal, the control module may determine that the wireless earphones are in the worn state.

[0111] The method for detecting the state of the wireless earphones provided by the embodiments of the present application can determine multiple different position states of the wireless earphones according to the intensity of the detected reflected signal and multiple threshold ranges. The method for detecting the state of the wireless earphones provided by the embodiments of the present application can detect the position state of the wireless earphones based on the intensity of the reflected signal formed after the detection signal sent by the sensor group is reflected by an obstacle, and does not rely on the traditional magnetic field intensity to detect the position state of the wireless earphones. Therefore, the process of detecting the state of the wireless earphones will not be interfered by an external magnetic field, and the accuracy of detecting the state of the wireless earphones can be improved.

[0112] Furthermore, the reflected signal is formed after the detection signal is reflected by an obstacle. Since the relative position between the obstacle and the sensor group is different, the intensity of the formed reflected signal is also different. Multiple position states of the wireless earphones can be determined according to different threshold ranges in which the intensity of the received reflected signal is located, further improving the accuracy of detecting the state of the wireless earphones.

[0113] In this embodiment, the earphone charging case may include a case body, and a storage cavity may be arranged in the case body. The case body may include a cover body and a housing body, and the cover body and the housing body may be movably connected. The housing body may be provided with a first accommodation cavity, and the cover body may be provided with a second accommodation cavity. The housing body may include an end face adapted to be covered by the cover body; when the cover body is covered on the end face, the first accommodation cavity and the second accommodation cavity may communicate with each other to jointly define the storage cavity. The sensor group may be arranged at a first ear-in position on the ear-in surface of the wireless earphones, and the first ear-in position may be the position on the ear-in surface opposite to the end face when the wireless earphones are accommodated in the storage cavity. Among them, the ear-in surface may be a side surface of the earphone body facing the ear canal when the wireless earphones are worn. Please refer to Figure 18 , step S130 may include steps: S131 - S132.

[0114] Step S131: If the intensity of the reflected signal falls within the first range, it is determined that the wireless earphones are in the stored state.

[0115] As an implementation manner, the control module can determine that when the intensity of the received reflected signal is within a first range, it indicates that the detection signal transmitted by the transmitter is enhanced and reflected by an obstacle to form a reflected signal, and the control module can determine that the wireless earphone is in a storage state.

[0116] Step S132: If the intensity of the reflected signal falls within a second range, it is determined that the wireless earphone is in a worn state.

[0117] As an implementation manner, the control module can determine that when the intensity of the received reflected signal is within a second range, it indicates that the detection signal transmitted by the transmitter is reflected by an obstacle to form a reflected signal, and the control module can determine that the wireless earphone is in a worn state.

[0118] In some implementation manners, in order to more accurately detect the state of the wireless earphone, the sensor group can be set to two, and the sensor group can include a first sensor group and a second sensor group. The first sensor group and the second sensor group are arranged at intervals on the earphone body, and the position state of different positions of the wireless earphone relative to the earphone charging case can be determined according to different sensor groups, which can improve the accuracy of the state detection of the wireless earphone. Please refer to Figure 19 , step S110 can include steps: S111 - S112.

[0119] Step S111: The transmitter of the first sensor group sends a first detection signal to the outside of the earphone body.

[0120] Step S112: The transmitter of the second sensor group sends a second detection signal to the outside of the earphone body.

[0121] In this embodiment, the first sensor group can be arranged at the second ear - in position. The second ear - in position can be the position on the ear - in surface located in the second accommodation cavity when the wireless earphone is accommodated in the storage cavity and the cover body covers the end surface. The second sensor group can be arranged at the third ear - in position. The third ear - in position can be the position on the ear - in surface located in the first accommodation cavity when the wireless earphone is accommodated in the storage cavity.

[0122] In some implementation manners, step S120 can include steps: S121 - S122.

[0123] Step S121: The receiver of the first sensor group receives a first reflected signal, and the first reflected signal is formed based on the first detection signal being reflected by an obstacle.

[0124] Step S122: The receiver of the second sensor group receives a second reflected signal, and the second reflected signal is formed based on the second detection signal being reflected by an obstacle.

[0125] In this embodiment, step S130 may further include step S133.

[0126] Step S133: Determine the current state of the wireless earphone according to the relationship between the intensity of the first reflection signal and a plurality of preset threshold ranges, and the relationship between the intensity of the second reflection signal and a plurality of preset threshold ranges.

[0127] In this embodiment, the control module may determine that the first intensity falls within a first threshold range according to the first intensity of the first reflection signal received by the first sensor group, and determine that the second intensity falls within a first range according to the second intensity of the second reflection signal received by the second sensor group, and it can be determined that the wireless earphone is in the storage state. The control module may also determine that the first intensity falls within a second range according to the first intensity of the first reflection signal received by the first sensor group, and determine that the second intensity falls within a second range according to the second intensity of the second reflection signal received by the second sensor group, and it can be determined that the wireless earphone is in the wearing state.

[0128] In this embodiment, by respectively arranging two sensor groups on the earphone body, the position states of two different positions on the wireless earphone relative to the earphone charging case can be respectively obtained, which can further improve the accuracy of the state detection of the wireless earphone.

[0129] In some embodiments, in order to more accurately detect the state of the wireless earphone, the wireless earphone may further include a charging module. The charging module may be arranged on the earphone body and may be electrically connected to the control module, so as to determine the position state of the wireless earphone relative to the earphone charging case according to the level state of the charging module. Please refer to Figure 20 , step S130 may further include steps: S134 - S136.

[0130] Step S134: Obtain the level state of the charging module.

[0131] In this embodiment, the charging module may be arranged at one end of the housing away from the ear - in surface. The charging module and the control module may be electrically connected through a main control circuit. As an example, the charging module may be a wired charging module, which may include a battery and charging pins. The charging pins may be electrically connected to the battery, and the charging pins may be used to conduct a power supply circuit when the wireless earphone is charging to charge the battery. Among them, the charging pins may include Pogo pin connectors, spring - piece connectors, etc. As another example, the charging module may be a wireless charging module, which may include a battery and an electromagnetic coil. The electromagnetic coil may be configured to generate an induced electromotive force to charge the battery when it is in a changing induction magnetic field. The specific setting method of the charging module is not limited herein and may be specifically set according to actual requirements.

[0132] Step S135: Determine the working state of the wireless earphone according to the level state of the charging module.

[0133] The control module can also be configured to determine the working state of the wireless earphone according to the level state of the charging module, and the working state can be used to represent the charging state and the non-charging state. As an example, the charging pin can include a Pogo pin connector. When the wireless earphone is connected to the earphone charging case, that is, when the earphone charging case charges the wireless earphone, the earphone charging case can apply a charging voltage to the Pogo pin connector, and a first level (high level) is generated between the Pogo pin connectors; when the wireless earphone is disconnected from the earphone charging case, that is, when the earphone charging case does not charge the wireless earphone, the earphone charging case fails to apply a voltage to the Pogo pin connector, and a second level (low level) is generated between the Pogo pin connectors. When detecting the current state of the wireless earphone, the control module can detect the level state of the Pogo pin connector. When the control module detects that the level state of the Pogo pin connector is the first level, it can be determined that the wireless earphone is in the charging state; when the control module detects that the level state of the Pogo pin connector is the second level, it can be determined that the wireless earphone is in the non-charging state.

[0134] Step S136: Determine whether the earphone charging case is closed when the wireless earphone is accommodated in the earphone charging case according to the relationship between the intensity of the reflected signal and a plurality of preset threshold ranges and the working state.

[0135] In this embodiment, the control module can determine the position state of the wireless earphone inside or outside the earphone charging case according to the working state of the wireless earphone, and can determine the state of whether the earphone charging case is closed or not closed when the wireless earphone is inside the earphone charging case according to the relationship between the intensity of the reflected signal and a plurality of preset threshold ranges, which can improve the accuracy of the state detection of the wireless earphone.

[0136] In some embodiments, in order to distinguish the reflection intensity of the detection signal by the earphone charging case, the earphone charging case can include a reflecting member, and the reflecting member can be disposed on the surface of the case body facing the receiving cavity. When the wireless earphone is accommodated in the receiving cavity, the reflecting member and the transmitter can be oppositely disposed to reflect the detection signal, and the reflecting member is used to enhance the reflection intensity of the detection signal.

[0137] Multiple threshold ranges may include a first range, a second range, and a third range. The lower limit value of the first range may be greater than the upper limit value of the second range, and the lower limit value of the second range may be greater than the upper limit value of the third range. The current state of the wireless earphones may include: a storage state where the wireless earphones are inside the earphone charging case and the earphone charging case is closed, an external state where the wireless earphones are neither inside the earphone charging case nor in the human ear, and other states other than the storage state and the external state.

[0138] In this embodiment, step S130 may further include: determining the relationship between the intensity and the first range, the second range, and the third range according to the intensity of the received reflected signal.

[0139] In this embodiment, the control module determines the relationship between the intensity and the first range, the second range, and the third range according to the intensity of the received reflected signal, including: if the intensity falls within the first range, determining that the current state of the wireless earphones is the storage state; if the intensity falls within the second range, determining that the current state of the wireless earphones is other states; if the intensity falls within the third range, determining that the current state of the wireless earphones is the external state.

[0140] In this embodiment, after the control module controls the receiver to receive the reflected signal, it may determine the intensity threshold range where the intensity is located according to the intensity of the reflected signal, and may determine the current state of the wireless earphones according to the intensity threshold range where the intensity is located. As an example, when the control module determines that the intensity is in the first range according to the intensity of the reflected signal, it may determine that the current state of the wireless earphones is the storage state; when the control module determines that the intensity is in the second range according to the intensity of the reflected signal, it may determine that the current state of the wireless earphones is other states; when the control module determines that the intensity is in the third range according to the intensity of the reflected signal, it may determine that the current state of the wireless earphones is the external state. Among them, the first range may be used to represent that the current state of the wireless earphones is the storage state, the second range may be used to represent that the current state of the wireless earphones is other states, and the third range may be used to represent that the current state of the wireless earphones is the external state.

[0141] In some embodiments, the second range may include a first sub-range and a second sub-range. The lower limit value of the first sub-range may be greater than the upper limit value of the third range, and the upper limit value of the first sub-range is less than the lower limit value of the second sub-range. Other states of the wireless earphones may include a wearing state where the wireless earphones are located in the human ear and an open-lid state where the wireless earphones are located in the earphone charging case and the headphone charging case is not closed. If the intensity falls within the second range, it is determined that the current state of the wireless earphones is other states, including: if the intensity falls within the first sub-range, it is determined that the current state of the wireless earphones is the open-lid state; if the intensity falls within the second sub-range, it is determined that the current state of the wireless earphones is the wearing state.

[0142] In this embodiment, when the control module determines that the intensity is within the second range based on the intensity of the reflected signal, and when it determines that the intensity is within the first sub-range, it can determine that the current state of the wireless earphones is the open-lid state; when the control module determines that the intensity is within the second range based on the intensity of the reflected signal, and when it determines that the intensity is within the second sub-range, it can determine that the current state of the wireless earphones is the wearing state. Among them, the first sub-range can be used to represent that the current state of the wireless earphones is the open-lid state, and the second sub-range can be used to represent that the current state of the wireless earphones is the wearing state.
