Description

Technical Field

[0001] This application relates to the field of smart device technology, and more particularly to a wireless headset and wearable device. Background Technology

[0002] With the continuous improvement of living standards, various smart devices (such as headphones, mobile phones, and wearable devices) have become an indispensable part of people's work, study, and leisure. Among them, wireless headphones are increasingly favored by consumers due to their high portability and small size. Furthermore, as consumers pursue a higher quality of life, their requirements for the wearing comfort of wireless headphones are also constantly increasing.

[0003] Wireless headphones mainly include in-ear and open-back types. Because in-ear wireless headphones can easily cause ear discomfort during prolonged wear, such as ear canal pain and stuffiness, and may even adversely affect hearing, open-back wireless headphones are becoming increasingly popular. Open-back wireless headphones include on-ear and clip-on types. On-ear wireless headphones are prone to falling out during exercise or rapid movement. Clip-on wireless headphones, on the other hand, are prone to insufficient clamping force, reducing the tightness of the fit, or excessive clamping force, causing excessive pressure on the wearer and easily leading to ear discomfort such as pain, thus reducing wearing comfort.

[0037] Compared with the prior art, the beneficial effects of this application are:

[0038] The wireless earphones and wearable devices provided in this application embodiment have an angled connection between the inclined and straight sections of the connecting arm. The clamping arm can rotate relative to the straight section to adjust the opening angle between them. On one hand, this allows the wearer to adjust the angle between the clamping arm and the straight section according to their ear shape, preventing excessive or insufficient clamping force. This reduces discomfort such as a foreign body sensation and pain when wearing the earphones, thus increasing the willingness of wearers, especially the elderly who are hesitant to wear earphones. On the other hand, because the inclined section will slightly sag under gravity after wearing, the angled connection between the inclined and straight sections allows the inclined section to be closer to the ear and fit more snugly when sag. This provides a better enclosure of the earphone within the space formed by the inclined section, straight section, and clamping arm, preventing the earphone from becoming loose during wear. This improves the wearing comfort and user experience of the wireless earphones. Attached Figure Description

[0060] Before explaining the technical solution of this application, the technical concept of this application will be explained first.

[0061] With the development of technology, modern technology and the environment have brought people a more exciting life, enriching their lifestyles and entertainment. Various smart devices (such as headphones, mobile phones, and wearable devices) are ubiquitous in people's work, study, and leisure. Among them, wireless headphones are increasingly favored by consumers due to their high portability and small size. Furthermore, as consumers pursue a higher quality of life, their demands for the wearing comfort of wireless headphones are also constantly increasing.

[0062] Wireless headphones mainly include in-ear and open-back types. However, in-ear wireless headphones can easily cause ear discomfort, such as ear canal pain and stuffiness, and may even adversely affect hearing, due to prolonged wear. Therefore, open-back wireless headphones are becoming increasingly popular. Open-back wireless headphones further include on-ear and clip-on types. On-ear wireless headphones tend to wobble during exercise or rapid movement, affecting the wearing experience and making them prone to falling out. While clip-on wireless headphones are less likely to fall out, due to differences in ear shape, they can either have insufficient clamping force, resulting in a loose fit and causing the headphones to wobble, or excessive clamping force, causing excessive pressure on the wearer and leading to ear discomfort such as pain, thus reducing the wearing experience and comfort.

[0063] To address the aforementioned issues, the inventors attempted to divide the wireless earphone's handle into a connecting section and a clamping section. One end of the connecting section is connected to the earphone body, while the clamping section is rotatable relative to the connecting section and connected to one end of the connecting section. During wear, the opening angle between the connecting section and the clamping section is adjusted by the rotation of the clamping section relative to the connecting section, and the clamping section and the earphone body together clamp the ear. However, while this method can prevent excessive or insufficient clamping force by adjusting the appropriate opening angle between the connecting section and the clamping section, the wireless earphone is still prone to slippage during wear due to excessive space created by the earphone body, connecting section, and clamping section. This causes the sound outlet of the wireless earphone to deviate from its intended direction, affecting the listening experience and wearing comfort.

[0064] In view of this, this application provides a wireless earphone and a wearable device. The wireless earphone features an angled connection between the inclined and straight sections of the connecting arm, and the clamping arm can rotate relative to the straight section to adjust the opening angle between the clamping arm and the straight section. This allows the wearer to adjust the appropriate opening angle between the clamping arm and the straight section according to their ear shape, thus preventing the clamping force of the wireless earphone from being too large or too small. Furthermore, the angled connection between the inclined and straight sections allows the inclined section to be closer to the human ear, resulting in a better enveloping effect of the space formed by the inclined section, the straight section, and the clamping arm on the human ear. This prevents the earphone from becoming loose during wear, reducing discomfort such as foreign body sensation and pain when wearing wireless earphones. This increases the willingness of wearers, especially the elderly who are reluctant to wear earphones, and improves the wearing comfort and user experience of the wireless earphone.

[0065] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0066] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a wireless earphone (in a first state) provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a wireless earphone (in a second state) provided in an embodiment of this application; Figure 3 This is a structural schematic diagram of a wireless earphone worn on a human ear from one perspective, according to an embodiment of this application. Figure 4 This is a schematic diagram of the structure of a wireless earphone worn on the human ear from another perspective, according to an embodiment of this application. Figure 5 This is a cross-sectional view of a wireless earphone provided in an embodiment of this application. In a first aspect, this application provides a wireless earphone 100, which includes an earphone body 1, a connecting arm 2, and a clamping arm 3. The earphone body 1 has a sound outlet 11. The connecting arm 2 includes an inclined section 21 and a straight section 22. One end of the inclined section 21 is connected to the earphone body 1, and the straight section 22 is connected to the other end of the inclined section 21. The straight section 22 and the inclined section 21 are arranged at an angle. The clamping arm 3 is rotatably connected to the straight section 22 and can rotate relative to the connecting arm 2 to change the opening angle θ between the clamping arm 3 and the straight section 22, so that the earphone body 1 is worn on the human ear 300.

[0067] The wireless earphone 100 provided in this application embodiment allows the clamping arm 3 to rotate relative to the straight section 22 to adjust the opening angle θ between the clamping arm 3 and the straight section 22. This enables the wearer to adjust the appropriate opening angle θ between the clamping arm 3 and the straight section 22 according to their ear shape, thereby avoiding situations where the clamping force of the wireless earphone 100 is too large or too small. This helps reduce discomfort such as foreign body sensation and pain when wearing the wireless earphone 100, thus increasing the wearing enthusiasm of wearers, especially the elderly who have a resistance to wearing earphones.

[0068] Considering that the tilted segment 21 of the wireless earphone 100 will sag slightly under gravity after being worn, this application further designs an angled arrangement between the tilted segment 21 and the straight segment 22. This allows the tilted segment 21 to be closer to the human ear 300 and to fit more snugly against the ear 300 when it sags. This results in a better enclosure of the earphone 300 within the space formed by the tilted segment 21, the straight segment 22, and the clamping arm 3, preventing the earphone body 1 from becoming loose during wear. This improves the wearing comfort of the wireless earphone 100 and enhances the user experience. Furthermore, the clamping arm 3 allows adjustment of the opening angle θ between the clamping arm 3 and the straight segment 22, enabling the wireless earphone 100 to be stored in the charging case. This saves space in the charging case and improves its space utilization. In particular, when the wireless earphone 100 is plugged into a wearable device, it facilitates the miniaturization of the wearable device.

[0069] Optionally, the earphone body 1 described above may be cylindrical, block-shaped, spherical, etc., and this embodiment does not limit this. To facilitate the description of the specific structure of the wireless earphone 100, the following description will take the earphone body 1 as a cylindrical shape as an example.

[0070] It is understandable that, such as Figure 1 and Figure 2 As shown, the earphone body 1 is generally cylindrical. The earphone body 1 has a wearing surface P along its cylindrical height direction and a first surface M opposite to the wearing surface P. The wearing surface P is configured to be close to or in contact with the human ear 300 when the earphone body 1 is worn on the human ear 300. The outer peripheral surface of the earphone body 1, the wearing surface P, and the first surface M together form the outer surface of the earphone body 1. When the earphone body 1 is cylindrical, the wearing surface P and the first surface M are two end faces along the extension direction of the earphone body 1 (i.e., the cylindrical height direction).

[0071] Optionally, such as Figure 1 and Figure 2 As shown, the sound outlet 11 is disposed on the first surface M or the outer peripheral surface of the earphone body 1. This allows the sound emitted by the wireless earphone 100 to be transmitted through the sound outlet 11 into the ear canal of the human ear 300, thereby achieving sound transmission from the wireless earphone 100. For example, the sound outlet 11 is disposed on the outer peripheral surface of the earphone body 1, and when the wireless earphone 100 is worn on the human ear 300, the opening of the sound outlet 11 is at least partially oriented towards the ear canal of the human ear 300. This alignment of the sound outlet 11 with the ear canal of the human ear 300 improves the sound output performance of the wireless earphone 100.

[0072] Optionally, a dustproof screen can be installed at the sound outlet 11. The dustproof screen can effectively block dust and other impurities from the external environment from entering the sound outlet 11, which helps to prevent the sound outlet 11 from becoming blocked.

[0073] Optionally, the aforementioned speaker component 13 may include, but is not limited to, an electrodynamic speaker, an electromagnetic speaker, a piezoelectric speaker, an electrostatic speaker, etc.

[0074] Optionally, such as Figure 1As shown, at the connection between the straight section 22 and the inclined section 21, a first included angle α is formed between the straight section 22 and the inclined section 21, with the first included angle α being 90°-180°. Through the obtuse first included angle α, when the earphone body 1 is worn on the human ear 300, the straight section 22 and the inclined section 21 can be closer to the human ear 300, thereby providing a better wrapping effect on the human ear 300 within the space formed by the inclined section 21, the straight section 22, and the clamping arm 3. This prevents the earphone body 1 from becoming loose during wear, improving the wearing comfort of the wireless earphone 100 and enhancing the user experience.

[0075] It is understood that the first included angle α mentioned above is 90°-180°, and can be, for example, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180°, 185°, etc. This embodiment does not limit this.

[0076] Optionally, the first included angle α, which is 90°-180°, can be: 90°-180°; 95°-180°; 100°-180°; 105°-180°; 110°-180°; 115°-180°; 120°-180°; 125°-180°; 130°-180°; 135°-180°; 140°-180°; 140°-175°; or 140°-170°. Alternatively, the first included angle α is 140°-165°. Alternatively, the first included angle α is 140°-160°. Alternatively, the first included angle α is 145°-160°. Alternatively, the first included angle α is 145°-155°. Alternatively, the first included angle α is 145°-150°, etc., and this embodiment does not limit this.

[0077] Optionally, the wireless earphone 100 has a first state and a second state, such as Figure 1 As shown, in the first state, the clamping arm 3 is unfolded relative to the straight section 22, and the earphone body 1 and the clamping arm 3 extend along the extension direction X of the straight section; as Figure 2As shown, in the second state, the clamping arm 3 and the straight section 22 are set at an angle, and the side of the earphone body 1 intended to be worn on the human ear 300 faces the clamping arm 3. Thus, in the first state, by inserting the wireless earphone 100 into the charging case along the extension direction X of the straight section, the wireless earphone 100 can be easily stored. In the second state, the angle between the clamping arm 3 and the straight section 22, and the orientation of the earphone body 1 intended to be worn on the human ear 300 towards the clamping arm 3, allows the earphone body 1 to be worn on the human ear 300, facilitating the wearing of the wireless earphone 100.

[0078] Please combine Figure 6 , Figure 6 This is a partially enlarged view of the connecting arm of a wireless headset provided in an embodiment of this application. As an optional implementation, such as... Figure 5 and Figure 6 As shown, the earphone body 1 has a wearing surface P and a first surface M opposite to the wearing surface P. The wearing surface P is configured to be close to or in contact with the human ear 300 when the earphone body 1 is worn on the human ear 300. The inclined segment 21 has a second surface N opposite to the wearing surface P, and the second surface N is set at an angle to the first surface M. By setting the second surface N of the inclined segment 21 at an angle to the first surface M of the earphone body 1, the inclined segment 21 can be closer to the human ear 300 when the earphone body 1 is worn on the human ear 300. Furthermore, the inclined segment 21 can fit more snugly to the human ear 300 when the straight segment 22 is slightly lowered. This results in a better wrapping effect of the space formed by the inclined segment 21, the straight segment 22, and the clamping arm 3 on the human ear 300, thereby preventing the earphone body 1 from becoming loose during wear. This improves the wearing comfort of the wireless earphone 100 and enhances the user experience.

[0079] Optionally, such as Figure 5 and Figure 6 As shown, a second included angle β is formed between the first surface M and the second surface N (for ease of labeling, the reference numerals for the second included angle β in the figures of this application are all shown at their apex angles), and the supplementary angle of the second included angle β is an acute angle. By setting the second included angle β as an obtuse angle, the inclined segment 21 and the straight segment 22 can better conform to the contour of the human ear 300, thereby providing a better wrapping effect on the human ear 300 within the space formed by the inclined segment 21, the straight segment 22, and the clamping arm 3. This is beneficial for improving the wearing stability of the wireless earphone 100, and thus for improving the wearing comfort of the wireless earphone 100 and the user experience.

[0080] Optionally, the supplementary angle of the second included angle β can be 20°-90°. In this way, the space formed by the inclined section 21, the straight section 22 and the clamping arm 3 can be further improved to enhance the wrapping effect of the human ear 300, which is conducive to further improving the wearing stability of the wireless earphone 100, and thus further improving the wearing comfort of the wireless earphone 100 and the user experience.

[0081] It is understood that the supplementary angle of the second included angle β is 20°-90°, and can be, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. This embodiment does not limit this.

[0082] Optionally, the supplementary angle of the second included angle β is 20°-90°, which can be: 20°-90°; 25°-90°; 30°-90°; 35°-90°; 40°-90°; 45°-90°; 45°-85°; 45°-80°; 45°-75°; 45°-70°; 45°-65°; or 45°-60°. Alternatively, the supplementary angle of the second included angle β is 45°-55°. Alternatively, the supplementary angle of the second included angle β is 45°-50°, etc., but this embodiment does not limit it.

[0083] As an optional implementation method, such as Figure 5 and Figure 6 As shown, the earphone body 1 is cylindrical and extends along the extension direction X of the straight section. This allows the wireless earphone 100 to be directly inserted into the charging case along the extension direction X when stored inside, facilitating storage and saving space in the charging case while improving its space utilization. In particular, when the wireless earphone 100 is connected to a wearable device, it contributes to the miniaturization of the wearable device.

[0084] Optionally, such as Figure 5As shown, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the flat section 22 is 3mm-8mm. By setting the range of the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the flat section 22, the flat section 22 can be made closer to the human ear 300 when worn. This further improves the wrapping effect of the space formed by the inclined section 21, the flat section 22 and the clamping arm 3 on the human ear 300, which is conducive to further improving the wearing stability of the wireless earphone 100, and thus further improving the wearing comfort of the wireless earphone 100 and the user experience.

[0085] Optionally, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the straight section 22 is 3mm-8mm, and can be, for example, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc. This application embodiment does not limit this.

[0086] Optionally, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the straight section 22 is 3mm-8mm. Specifically, it can be 3.5mm-8mm, 4mm-8mm, 4mm-7.5mm, 4mm-7mm, 4mm-6.5mm, or 4mm-6mm. Alternatively, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the straight section 22 may be 4mm-5.5mm. Alternatively, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the straight section 22 may be 4mm-5mm. Alternatively, the minimum distance D between the outer peripheral surface of the earphone body 1 and the outer peripheral surface of the straight section 22 may be 4mm-4.5mm, etc., and this embodiment does not limit this.

[0087] To improve the sound output of the wireless earphone 100, the positions of the sound outlet 11 and the speaker component 13 can be redesigned. Specifically, for example... Figure 5 and Figure 6As shown, the headphone body 1 includes a headphone shell 12, a speaker component 13, and a battery 14. The headphone shell 12 includes an outer casing, which is cylindrical and extends along the extension direction X of the straight section. Along the extension direction of the outer casing, the battery 14 and the speaker component 13 are sequentially disposed inside the outer casing, with the battery 14 located on the side where the front sound cavity of the speaker component 13 is located. The sound outlet 11 is disposed in the outer casing and located between the speaker component 13 and the battery 14. In this manner, when the wireless headphone 100 is worn on the human ear 300, the battery 14 is closer to the wearing surface P. On the one hand, this makes the center of gravity of the wireless headphone 100 closer to the human ear 300, which can prevent the wireless headphone 100 from flipping outward due to the gravity of the side away from the human ear 300 when worn, thus improving the wearing stability of the wireless headphone 100. On the other hand, it allows the sound outlet 11 to be better aligned with the ear canal of the human ear 300 when the wireless headphone 100 is worn, thereby improving the sound output effect of the wireless headphone 100. Furthermore, compared to placing the speaker component 13 closer to the wearing surface P, this method allows the speaker component 13 to be placed away from the auricle of the human ear 300, thus freeing it from the limitations of the auricle size. This allows for the selection of a larger speaker component 13, which in turn provides better sound quality and improves the sound quality of the wireless headphones 100.

[0088] Optionally, the projection of the battery 14 onto a plane perpendicular to the extension direction of the outer casing is located within the projection range of the speaker component 13 onto a plane perpendicular to the extension direction of the outer casing. In this way, on the one hand, the speaker component 13 has a larger size, and the larger speaker component 13 has better sound quality, thus improving the sound quality of the wireless earphone 100; on the other hand, because the battery 14 near the wearing surface P is smaller, the end of the earphone body 1 near the wearing surface P is smaller, allowing the earphone body 1 to better fit the concha of the human ear 300, and avoiding any pressure on the concha of the human ear 300, thus improving the wearing comfort of the wireless earphone 100.

[0089] It is understandable that when the wireless earphone 100 is stored in the charging case, in order to prevent the wireless earphone 100 from falling off, a magnetic component can be provided to allow the wireless earphone 100 to be attached to the charging case. The magnetic component may include one or more, and this embodiment does not limit it.

[0090] Optionally, when there are multiple magnetic components, there can be 1, 2, 3, 4, etc., and this embodiment does not limit this.

[0091] Optionally, when there are multiple magnetic components, the multiple magnetic components can provide attraction in the same direction or attraction in different directions; this embodiment does not limit this. For example, such as... Figure 5 and Figure 6 As shown, the wireless earphone 100 also includes a first magnetic member 41 and a second magnetic member 42. The first magnetic member 41 is disposed inside the outer shell and along the extending direction of the outer shell, the first magnetic member 41 is disposed on the side of the battery 14 opposite to the speaker component 13. The second magnetic member 42 is disposed on the side of the flat section 22 near the earphone body 1 and is located inside the flat section 22. The first magnetic member 41 and the second magnetic member 42 provide better magnetic force when the wireless earphone 100 is stored in the charging case, which helps to prevent the wireless earphone 100 from falling out of the charging case during activities. In particular, when the wireless earphone 100 is plugged into a wearable device, the first magnetic member 41 and the second magnetic member 42 can provide magnetic force in different directions, which helps to firmly attach the wireless earphone 100 to the receiving position of the wearable device.

[0092] To improve the space utilization and miniaturization of the wireless earphone 100, this application also designs the stacking of electronic components such as the circuit board 24 and microphone 25 of the wireless earphone 100, as detailed below:

[0093] As an optional implementation method, such as Figure 5 and Figure 6 As shown, the connecting arm 2 has a microphone hole 23, and a mounting cavity 2a is formed inside the connecting arm 2. The mounting cavity 2a is connected to the microphone hole 23. A circuit board 24 and a microphone 25 are disposed in the mounting cavity 2a. The microphone 25 is electrically connected to the circuit board 24 and is positioned corresponding to the microphone hole 23. By utilizing the internal space of the connecting arm 2 and stacking electronic components such as the circuit board 24 and the microphone 25 within the internal space of the connecting arm 2, the space utilization rate of the connecting arm 2 is improved, which in turn improves the space utilization rate of the wireless earphone 100. Furthermore, placing the microphone 25 inside the connecting arm 2 allows it to be positioned away from the sound outlet 11, thereby avoiding interference from the sound output of the speaker component 13 and improving the sound pickup effect of the microphone 25.

[0094] Please combine Figure 7 , Figure 7This is a schematic diagram of the circuit board structure of a wireless earphone according to an embodiment of this application. Optionally, the circuit board 24 includes a first rigid board 241, a second rigid board 242, and a first flexible board 243. The first rigid board 241 is disposed inside the inclined section 21, the second rigid board 242 is disposed inside the straight section 22, one end of the first flexible board 243 is connected to the first rigid board 241, and the other end of the first flexible board 243 is connected to the second rigid board 242. The first flexible board 243 is electrically connected to the first rigid board 241 and the second rigid board 242. By using a rigid-flex circuit board 24, the circuit board 24 and the microphone 25 can be better arranged within the internal space of the straight section 22 and the inclined section 21 of the connecting arm 2, which is beneficial to further improving the space utilization of the connecting arm 2, thereby further improving the space utilization of the wireless earphone 100.

[0095] Optionally, such as Figure 6 and Figure 7 As shown, the aforementioned microphone 25 includes multiple microphones, which are positioned far apart from each other. For example, two microphones 25 are included: one microphone 25 is located within the inclined section 21 near the end of the earphone body 1, and the other microphone 25 is located within the straight section 22 near the end of the clamping arm 3. By positioning the multiple microphones far apart, on the one hand, the sound wave intensity of the microphones 25 at different positions varies, thereby improving the noise reduction effect of the wireless earphone 100; on the other hand, positioning the multiple microphones far apart reduces signal interference between the microphones 25, which is beneficial for improving the sound pickup effect of the microphones 25. Furthermore, by setting multiple microphones 25, some microphones 25 can be used to enable the wireless earphone 100 to perform call functions, while others can be used to enable the wireless earphone 100 to perform hearing assistance functions, thus providing hearing assistance to elderly people who may have hearing impairments.

[0096] Optionally, such as Figure 6 and Figure 7As shown, the circuit board 24 also includes a second flexible board 244 and a third flexible board 245. The second flexible board 244 is disposed inside the inclined section 21 and is electrically connected to the first rigid board 241. The third flexible board 245 is disposed inside the straight section 22 and is connected to the second rigid board 242. The microphone 25 includes at least two microphones. The sound receiving hole 23 includes a first sub-sound receiving hole 231 and a second sub-sound receiving hole 232. The first sub-sound receiving hole 231 is disposed in the inclined section 21 and the second sub-sound receiving hole 232 is disposed in the straight section 22. Among the at least two microphones 25, one microphone 25 is disposed in the inclined section 21 corresponding to the first sub-sound receiving hole 231 and is electrically connected to the second flexible board 244, and the other microphone 25 is disposed in the straight section 22 corresponding to the second sub-sound receiving hole 232 and is electrically connected to the third flexible board 245. The microphone 25 is connected to the cavity wall of the mounting cavity 2a. In this way, on the one hand, the second flexible circuit board 244 and the third flexible circuit board 245 can realize the electrical connection of the microphone 25; on the other hand, by setting the two microphones 25 in the inclined section 21 and the straight section 22 respectively, the sound pickup effect of the two microphones 25 can be improved and the mutual interference of the two microphones 25 can be avoided, which is conducive to improving the call effect or auxiliary hearing effect of the wireless headset 100.

[0097] In some embodiments, to facilitate the assembly of the wireless earphone 100, at least two of the first rigid board 241, the second rigid board 242, the first flexible board 243, the second flexible board 244, and the third flexible board 245 can be integrally disposed. As an example, the first rigid board 241 and the first flexible board 243 are integrally disposed.

[0098] Another example is that the first flexible board 243 and the second rigid board 242 are integrated into one unit.

[0099] Another example is that the first rigid board 241 and the second flexible board 244 are integrated into one unit.

[0100] Another example is that the second rigid board 242 and the third flexible board 245 are integrated into one unit.

[0101] In another exemplary configuration, the first rigid board 241, the first flexible board 243, and the second flexible board 244 are integrally disposed.

[0102] In another exemplary configuration, the second rigid board 242, the first flexible board 243, and the third flexible board 245 are integrated into one unit.

[0103] In another exemplary configuration, the first rigid board 241, the second rigid board 242, and the first flexible board 243 are integrally formed.

[0104] In another exemplary configuration, the first rigid board 241, the second rigid board 242, the first flexible board 243, and the second flexible board 244 are integrally arranged.

[0105] In another exemplary configuration, the first rigid board 241, the second rigid board 242, the first flexible board 243, and the third flexible board 245 are integrated into one unit.

[0106] Another example, such as Figure 7 As shown, the first rigid board 241, the second rigid board 242, the first flexible board 243, the second flexible board 244, and the third flexible board 245 are integrally arranged.

[0107] The integrated arrangement of the first rigid board 241, the second rigid board 242, the first flexible board 243, the second flexible board 244, and the third flexible board 245 facilitates the assembly of the wireless earphone 100 and helps to reduce the assembly process of the wireless earphone 100.

[0108] As an optional implementation method, such as Figure 5 As shown, the wireless earphone 100 also includes a charging connector 5, which is disposed on the surface of the inclined section 21 near the earphone body 1, and is electrically connected to the circuit board 24. The charging connector 5 on the inclined section 21 enables charging of the wireless earphone 100; furthermore, compared to placing the charging connector 5 on the straight section 22, it avoids friction between the charging connector 5 and the inner wall of the charging case when the wireless earphone 100 is stored inside, thus preventing damage to the charging connector 5 and extending the lifespan of the wireless earphone 100.

[0109] It is understood that there are multiple implementations for the clamping arm 3 to be rotatably connected to the straight section 22. The clamping arm 3 can be rotatably connected to the straight section 22 via a rotating shaft 61; or the clamping arm 3 can be connected to the straight section 22 via an elastic element, or the clamping arm 3 can be rotatably connected to the straight section 22 via the bending of the elastic element, etc. This embodiment does not limit this.

[0110] Optionally, such as Figure 6 As shown, the wireless earphone 100 also includes a connector 6, which connects the straight section 22 and the clamping arm 3. The connector 6 is configured to allow the clamping arm 3 to rotate relative to the straight section 22, thereby changing the opening angle θ between the clamping arm 3 and the straight section 22. Through the connector 6, on the one hand, the clamping arm 3 can be rotatably connected to the straight section 22; on the other hand, the opening angle θ between the clamping arm 3 and the straight section 22 can be maintained, allowing the earphone body 1 to be worn on the human ear 300.

[0111] Optionally, the connector 6 includes a pivot 61 or an elastic element. When the connector 6 includes an elastic element, the elastic element is configured to bend and deform to change the opening angle θ between the clamping arm 3 and the straight section 22. In this way, the clamping arm 3 can be rotatably connected to the straight section 22 via the pivot 61 or the elastic element. Furthermore, the pivot 61 allows for better rotation of the clamping arm 3, thereby adjusting the opening angle θ between the clamping arm 3 and the straight section 22.

[0112] Optionally, the aforementioned rotating shaft 61 includes a single-cell structure damping rotating shaft 61, a spring-loaded damping rotating shaft 61, an overlapping damping rotating shaft 61, etc., and this embodiment does not limit this. By setting the rotating shaft 61 as a damping rotating shaft 61, both the rotation of the clamping arm 3 relative to the straight section 22 and the maintenance of the angle between the clamping arm 3 and the straight section 22 can be achieved. In addition, by using the damping rotating shaft 61, the way the clamping arm 3 can rotate relative to the straight section 22 is simple, which helps to simplify the manufacturing process of the wireless earphone 100, thereby improving the production efficiency of the wireless earphone 100.

[0113] Optionally, the above-mentioned elastic element includes shape memory metal sheet, soft rubber sheet, spring sheet, etc., and this embodiment does not limit it.

[0114] As an optional implementation method, such as Figure 6 As shown, a concave surface 31 is provided on the side surface of the clamping arm 3 near the earphone body 1. The concave surface on the side surface of the clamping arm 3 can increase the rotation angle of the clamping arm 3 relative to the straight section 22, which is beneficial to increase the angle range between the clamping arm 3 and the straight section 22. This allows the distance between the end of the clamping arm 3 away from the straight section 22 and the wearing surface P of the earphone body 1 to be smaller, thereby enabling the wireless earphone 100 to adapt to the ear contour size of more people and improving the applicability of the wireless earphone 100 to a wider range of people.

[0115] Optionally, such as Figure 6 As shown, the angle at which the clamping arm 3 can rotate relative to the straight section 22 is 0°-160°, that is, the opening and closing angle θ between the clamping arm 3 and the straight section 22 is 0°-160°. By setting the range of the angle at which the clamping arm 3 can rotate relative to the straight section 22, the distance between the end of the clamping arm 3 away from the straight section 22 and the wearing surface P of the earphone body 1 can be smaller, thereby enabling the wireless earphone 100 to adapt to the ear contour size of more people, which is beneficial to improving the applicability of the wireless earphone 100 to the target audience.

[0116] It is understood that the angle at which the clamping arm 3 can rotate relative to the straight section 22 is 0°-160°, and can be, for example, 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc. This embodiment does not limit this.

[0117] It is understandable that the first state mentioned above refers to the angle at which the clamping arm 3 can rotate relative to the straight section 22 being 0°, that is, the opening and closing angle θ between the clamping arm 3 and the straight section 22 being 0°.

[0118] As an optional implementation, the headphone body 1 and the tilting section 21 are integrated into one unit.

[0119] Optionally, the inclined section 21 and the straight section 22 are integrated.

[0120] Optionally, the headphone body 1, the tilt section 21, and the straight section 22 are integrated into one unit.

[0121] The above-mentioned method of integrating the earphone body 1, the inclined section 21, and the straight section 22 into one unit can save the assembly process between the earphone body 1, the inclined section 21, and the straight section 22, which is conducive to the assembly of the wireless earphone 100, thereby improving the assembly efficiency of the wireless earphone 100 and thus improving the production efficiency of the wireless earphone 100.

[0122] It is understandable that, in order to facilitate the installation of components such as the speaker component 13, battery 14, circuit board 24, and microphone 25, the bottom shell of the headphone body 1, the tilt section 21, and the straight section 22 can be integrated into one piece, and the top shell of the headphone body 1, the tilt section 21, and the straight section 22 can be integrated into one piece, with the top shell connected to the bottom shell and forming an installation space inside.

[0123] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the structure of a wearable device (wireless earphone plugged into the receiving position) provided in an embodiment of this application; Figure 9This is a schematic diagram of the structure of a wearable device (wireless earphone detached from its housing) provided in an embodiment of this application. In a second aspect, this application also provides a wearable device 200, including a main body 201 and a wireless earphone 100 as described in the first aspect above. The main body 201 is provided with a housing 202, which is configured to allow the wireless earphone 100 to be plugged into and detachably connected to the main body 201. By providing installation space for the wireless earphone 100 through the housing 202 on the wearable device 200, a separate charging case for the wireless earphone 100 is not required, making the wireless earphone 100 easier to carry.

[0124] Optionally, the wearable device 200 mentioned above includes, but is not limited to, watches, bracelets, smart jewelry, and glasses. To facilitate the description of the specific structure of the wearable device 200, a watch will be used as an example below.

[0125] Please combine Figure 10 and Figure 13 , Figure 10 This is a partial cross-sectional view of a wearable device (wireless earphone plugged into the receiving position) provided in an embodiment of this application; Figure 11 yes Figure 10 A magnified view of a section at point C;

[0126] Figure 12 This is a partial cross-sectional view of a wearable device (wireless earphone detached from its housing) provided in an embodiment of this application; Figure 13 yes Figure 12 A magnified view of a portion at point D. As an alternative implementation, such as... Figure 8 and Figure 9 As shown, the earphone body 1 is pluggably connected to the receiving position 202 along the extension direction X of the straight section. This method facilitates the plugging and unplugging of the wireless earphone 100, simplifying the plugging and unplugging process and improving the user experience. Furthermore, it reduces the installation space required for the wireless earphone 100, saving space in the main body 201 of the wearable device 200, thus improving the space utilization of the wearable device 200 and facilitating its miniaturization.

[0127] Optionally, such as Figures 10 to 13As shown, the wearable device 200 also includes a wearable component 203, which is connected to the main body 201. The receiving position 202 includes a first sub-receiving position 2021 and a second sub-receiving position 2022. The first sub-receiving position 2021 and the second sub-receiving position 2022 are connected, and the second sub-receiving position 2022 is disposed between the main body 201 and the wearable component 203. The earphone body 1 and the tilting section 21 are pluggably connected to the first sub-receiving position 2021, and the straight section 22 and the clamping arm 3 are pluggably connected to the second sub-receiving position 2022. By utilizing the space between the wearable component 203 and the main body 201 to set up the second sub-receiving position 202, the space of the main body 201 of the wearable device 200 can be further saved, thereby improving the space utilization rate of the wearable device 200 and facilitating the miniaturization design of the wearable device 200. Furthermore, when the wearable device 200 is a watch, the tilt section 21 is positioned to fit the transition shape between the wearable component 203 and the side surface of the main body 201 where the receiving position 202 is provided, which helps to improve the aesthetics of the wearable device.

[0128] It is understood that when the wearable device 200 is a watch, the wearing component 203 is the watch strap. When the wearable device 200 is eyeglasses, the wearing component 203 is the temple, and so on. This embodiment does not limit this.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
