[0046] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0047] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0048] Combination Figure 1 The user's ear 500 may include an external auditory canal 501, a concha 502, a cymba 503, a triangular fossa 504, an antihelix 505, a scaphoid 506, a helix 507, and a tragus 508. Although the external auditory canal 501 has a certain depth and extends to the eardrum, for the sake of convenience, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 501 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 502, the hymena conchae 503, the triangular fossa 504 and other physiological parts have a certain volume and depth; and the concha cavity 502 is directly connected to the external auditory canal 501, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 502.

[0049] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. For the convenience of description, and to reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears, such as GRAS 45BC KEMAR, can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards. Therefore, in this application, descriptions such as "the user wears the earphone 100", "the earphone 100 is in a wearing state" and "in a wearing state" may refer to the earphone 100 described in this application being worn on the ear of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphone 100 worn by different users and the earphone 100 worn on the ear of the aforementioned simulator, but such differences should be tolerated.

[0050] See also Figures 2 to 5, the earphone 100 may include a host module 1 and an ear hook 2, and the host module 1 may include a shell assembly 10 and a speaker 13. The host module 1 may also include a battery 14. The ear hook 2 may be in a hook shape, and the earphone 100 may be worn on the user's ear through the ear hook 2. The ear hook 2 may be connected to the shell assembly 10. In the wearing state, the shell assembly 10 is located on the front side of the ear, and the ear hook 2 is at least partially located on the back side of the user's ear, so that the earphone 100 is hung on the ear. In addition, the shell assembly 10 may be used to form an accommodating space 101. The speaker 13 may be arranged in the accommodating space 101 to provide air-conducted sound to the external auditory canal of the user's ear. The battery 14 may also be arranged in the accommodating space 101.

[0051] For the convenience of describing the shape of the housing assembly 10, the present application defines that the housing assembly 10 has a first direction X and a second direction Y, wherein the first direction X may be orthogonal to the second direction Y (see Figure 5 ). The first direction X may refer to the length direction of the housing assembly 10 , and the second direction Y may refer to the thickness direction of the housing assembly 10 .

[0052] The housing assembly 10 is stacked on the front side of the user's ear along the second direction Y. The housing assembly 10 further has a first end 102 and a second end 103 disposed opposite to each other along the first direction X. The first end 102 may refer to a portion facing the user's concha cavity 502 during wearing, and the second end 103 may refer to a portion further away from the user's concha cavity 502 relative to the first end 102. The second end 103 may be connected to the ear hook 2, and may be referred to as the connection end 102 hereinafter, while the first end 102 may also be referred to as the free end 103 hereinafter.

[0053] The first end 102 of the shell assembly 10 at least partially extends into the concha cavity 502 of the user's ear, and the external auditory canal of the user's ear is in an open state. The user's external auditory canal is in an open state means that the shell assembly 10 does not completely close the external auditory canal. In addition, due to individual differences between different users, when the earphone 100 is worn by different users, the shell assembly 10 may partially block the external auditory canal, but the external auditory canal is still not completely blocked.

[0054] In summary, when the user wears the earphone 100, the ear hook 2 is hung on the ear of the user and is partially located behind the ear of the user, the shell assembly 10 is located in front of the ear of the user, and the second end 103 of the shell assembly 10 can extend into the user's concha cavity 502. In addition, the ear hook 2 can be connected to the second end 103 of the shell assembly 10 or a portion close to the second end 103. Due to the shape of the ear, the shape of the ear hook 2 and the installation position of the first end 102 of the shell assembly 10, the second end 103 of the shell assembly 10 is usually located in front of, above or front-upper of the first end 102 during wearing.

[0055] Optionally, the battery 14 can supply power to the speaker 13. Optionally, in the wearing state, the first end 102 is closer to the concha cavity 502 of the user's ear than the second end 103, the speaker 13 is arranged near the first end 102, and the battery 14 is arranged near the second end 103. In this case, it is more conducive for the speaker 13 to emit air conduction sound to the user's external auditory canal.

[0056] Optionally, the speaker 13 and the battery 14 are spaced apart in the accommodating space 101 along the first direction X. In this case, the speaker 13 and the battery 14 can be assembled in the housing assembly 10 at the same time, thereby improving assembly efficiency and reducing the use of leads.

[0057] Optionally, the housing assembly 10 may have a partition wall 104 for separating the speaker 13 from the battery 14. In this case, the partition wall 104 can separate the battery 14 from the speaker 13, reducing the possibility that the water vapor in the speaker 13 contaminates the battery 14.

[0058] Alternatively, see Figure 5 , the speaker 13 has a first axis ZX1. The battery 14 has a second axis ZX2. The first axis ZX1 and the second axis ZX2 respectively have positive directions pointing to the user's ears in the worn state. In the reference plane defined by the first direction X and the second direction Y. The positive direction of the first axis ZX1 and the projection of the second axis ZX2 in the reference plane are arranged crosswise. Among them, the first axis ZX1 can be parallel to the vibration direction of the diaphragm of the speaker 13, and pass through the center of gravity of the speaker 13, the geometric center or the centroid of its end face (such as a circular end face, a runway-shaped end face). The second axis ZX2 can refer to the axis passing through the axis of symmetry of the battery 14, and the axis passing through the geometric center or the centroid of its two end faces.

[0059] In this case, the speaker 13 and the battery 14 are arranged relatively tilted, which is beneficial to reducing the length of the shell assembly 10 in the first direction X compared to arranging the speaker 13 and the battery 14 side by side, so that the shell assembly 10 can be stably supported and extended into the concha cavity 502 when worn.

[0060] Optionally, the intersection angle θ of the projection of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in the reference plane is an acute angle. Optionally, the intersection angle θ of the projection of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in the reference plane is located on the side of the housing assembly 10 facing the user's ear. Optionally, the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 is between 10° and 14° or between 11° and 14°.

[0061] In this case, the speaker 13 is tilted relatively greatly relative to the battery 14 , and the projected length of the speaker 13 in the first direction X will gradually decrease, which is beneficial to shortening the length of the housing assembly 10 in the first direction X.

[0062] Optionally, on the reference plane, the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, the second direction Y has a positive direction pointing to the user's ear, and the intersection angle θ between the projection of the positive direction of the first axis ZX1 in the reference plane and the positive direction of the second direction Y is greater than the intersection angle θ between the projection of the positive direction of the second axis ZX2 in the reference plane and the positive direction of the second direction Y. Optionally, the second axis ZX2 is arranged parallel to the second direction Y. Among them, the radial dimension of the speaker 13 may refer to the length of the direction perpendicular to its first axis ZX1 in the cross section on the reference plane. The radial dimension of the battery 14 may refer to the length of the direction perpendicular to its second axis ZX2 in the cross section on the reference plane.

[0063] In this case, since the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, when the speaker 13 is arranged obliquely relative to the second direction Y, the change in the projected length of the speaker 13 in the first direction X is greater than when the battery 14 is arranged obliquely relative to the second direction Y, thereby facilitating the reduction of the length of the housing assembly 10 in the first direction X. In addition, the speaker 13 is inclined relative to the battery 14, and while the second end 103 of the speaker 13 (where the battery 14 is disposed) is attached to the skin in front of the user's tragus 508, the diaphragm of the speaker 13 can be roughly oriented toward the user's external auditory canal, thereby facilitating the sound propagation of the speaker 13 toward the user's external auditory canal.

[0064] Optionally, the headset 100 further includes a circuit board 15 disposed in the accommodating space 101. The circuit board 15 controls the speaker 13 to vibrate and emit sound when the battery 14 supplies power. In addition, the circuit board 15 may also have a radio frequency module for communication connection with a mobile terminal.

[0065] Optionally, the circuit board 15 is disposed on the housing assembly 10 and is located on the side of the speaker 13 and the battery 14 away from the user's ear, and the projection along the second direction Y overlaps with the speaker 13 and the battery 14. The overlap of the projection of the circuit board 15 and the speaker 13 and the battery 14 may be partial overlap or complete overlap. In this case, the speaker 13 can be disposed on the side close to the user's ear, which is conducive to transmitting sound to the user's ear.

[0066] Specifically, the shell assembly 10 includes a first shell 111 and a second shell 112 that match each other along the second direction Y. The first shell 111 is located on the side of the second shell 112 that is away from the user's ear. The speaker 13 and the battery 14 can be fixed to the first shell 111, and the first shell 111 is closer to the user's ear than the second shell 112 when worn, and the circuit board 15 is fixed to the second shell 112. In this case, it can facilitate the assembly of the headset 100 and the disassembly and repair of the headset 100. Optionally, the circuit board 15 is fixed to the second shell 112 of the shell assembly 10 by hot melting.

[0067] See also Figure 6 Optionally, the earphone 100 further includes a charging interface 16 disposed on the first shell 111 and a magnetic element 17 disposed between the battery 14 and the first shell 111 along the second axis ZX2. In this case, the earphone 100 can be used in conjunction with a charging box with a magnetic charging function. The charging interface 16 can penetrate the outer wall surface LS2 of the first shell 111 and be exposed through the outer wall surface LS2 for contact charging.

[0068] See also Figure 7 The charging box 900 may include a lower shell component 910 and an upper shell component 920. The lower shell component 910 may be provided with two contoured grooves 911 for accommodating the earphone 100 respectively. The upper shell component 920 may cover the lower shell component 910 to close the contoured groove 911.

[0069] Furthermore, the charging box 900 may include a main control circuit board arranged in the lower shell assembly 910 and electrode terminals 912 arranged on the main control circuit board. Among them, the electrode terminals 912 can be set in multiple groups, such as two groups, as required. Accordingly, when any earphone 100 is placed in the charging box 900, the charging interface 16 in the earphone 100 can be in one-to-one contact with the electrode terminals 912 in the charging box 900 to meet the requirements of charging, detection and other functions. Accordingly, the electrode terminal 912 may include a positive power supply terminal and a negative power supply terminal, and may further include a detection terminal; the lines connecting them may form a triangle, such as an equilateral triangle, or they may be spaced apart along a straight line, such as spaced apart from each other and collinear.

[0070] Optionally, the electrode terminal 912 may be exposed in the contoured groove 911 . When the earphone 100 is received in the contoured groove 911 , the charging interface 16 is electrically connected to the electrode terminal 912 .

[0071] In addition, the charging box 900 may include a magnetic attraction structure (not shown) disposed in the lower shell assembly 910. The magnetic attraction structure may be provided in multiple groups, for example, two groups, as required. After any earphone 100 is placed in the contoured groove 911, the magnetic attraction structure and the magnetic attraction element 17 in the earphone 100 may form a magnetic attraction pair, so that the charging interface 16 is in one-to-one contact with the electrode terminal 912.

[0072] Several exemplary structures of the ear hook 2 of the headset 200 are shown below. Different exemplary structures can also be combined with each other to obtain other exemplary structures belonging to this embodiment that are not described in detail.

[0073] In order to improve the wearing comfort of the ear hook 2, see the first example structure of the ear hook 2 as follows:

[0074] like Figure 8 As shown, the headset 100 may include a host module 1 and an ear hook 2. The ear hook 2 is arranged in a curved shape and has a first end 201 and a second end 202 away from the first end 201, and the first end 201 is connected to the host module 1. The ear hook 2 is used to be hung on the ear of the user, and the ear hook 2 includes an elastic frame 21 and a covering 22, the elastic frame 21 is extended along the extension direction of the ear hook 2, the covering 22 is covered on the elastic frame 21, and the covering 22 is provided with a buffer cavity 220.

[0075] By providing an ear hook 2 including an elastic skeleton 21 and a covering 22, wherein both the elastic skeleton 21 and the covering 22 have certain elastic limits and can be elastically deformed within their respective elastic limits, the ear hook 2 can be elastically deformed to fit the ear when the user wears the earphone 100, thereby effectively improving the wearing comfort and stability. By providing a buffer cavity 220 in the covering 22, the covering 22 can be more easily elastically deformed when the user wears the earphone 100, and can adapt to different ear widths, thereby better fitting the user's ear and realizing an adaptive function. In addition, due to the presence of the buffer cavity 220, when the covering 22 contacts the ear, the contact area between the covering 22 and the user's ear can be increased, thereby reducing the pressure exerted by the covering 22 on the ear and improving the user's wearing comfort.

[0076] Furthermore, if Figure 8 As shown, in the first end 201 and the second end 202 , the buffer cavity 220 is closer to the second end 202 .

[0077] The second end 202 is farther away from the main module 1 than the first end 201. The buffer cavity 220 is set at a position closer to the second end 202. This can ensure that the part close to the second end 202 is more prone to elastic deformation than the part close to the first end 201 when the user wears it. While ensuring the connection stability between the main module 1 and the ear hook 2, the adaptability of the ear hook 2 is improved, effectively improving the wearing comfort of the user.

[0078] Furthermore, if Fig. 9 As shown, the covering member 22 has a rear covering section 222 located at the rear side of the ear when worn, the second end 202 is located at the rear covering section 222 , and the buffer cavity 220 is opened in the rear covering section 222 .

[0079] When the earphone 100 is in the wearing state, the ear hook 2 is hung on the user's ear around the outer circumference of the ear, and the rear covering section 222 is located at the rear side of the ear. Opening the buffer cavity 220 in the rear covering section 222 can increase the deformation range of the rear covering section 222, so as to better adapt to the use of users with different ear widths, effectively reduce the pressure exerted by the ear hook 2 on the back side of the user's ear, and provide the user with a better wearing experience.

[0080] Alternatively, if Fig. 9 As shown, the host module 1 includes a connecting end 103 connected to the first end 201 of the ear hook 2 and a free end 102 away from the connecting end 103, at least a portion of the rear covering section 222 is arranged opposite to the free end 102, and at least a portion of the buffer cavity 220 is located at a portion of the rear covering section 222 that is arranged opposite to the free end 102.

[0081] At least a portion of the rear covering section 222 is arranged opposite to the free end 102, and at least a portion of the buffer cavity 220 is located at the portion of the rear covering section 222 that is arranged opposite to the free end 102, so that when the user wears the earphone 100, the rear covering section 222 and the free end 102 are respectively located on both sides of the ear, and the rear covering section 222 located on the back side of the ear can adaptively undergo elastic deformation, thereby effectively reducing the pressure applied to the user's ear when wearing, thereby improving the user's wearing comfort.

[0082] Furthermore, if Figure 8 and Fig. 9 As shown, the free end 102 is configured to extend into the concha cavity 502 of the ear when in the worn state, and the free end 102 and the rear covering section 222 are configured to clamp the ear area from the front and back sides of the ear area corresponding to the concha cavity 502 when in the worn state, and the buffer cavity 220 is located in the portion of the rear covering section 222 for clamping the ear area.

[0083] When the earphone 100 is worn, the free end 102 extends into the concha cavity 502, so that the rear covering section 222 and the free end 102 can be clamped on the front and rear sides of the ear of the user when the user wears the earphone 100, thereby increasing the wearing stability and reducing the possibility of the earphone 100 falling off. The portion of the rear covering section 222 used for clamping the ear area is the portion that applies relatively large pressure to the ear of the user, and arranging the buffer cavity 220 in this portion can reduce the pressure applied to the ear by the rear covering section 222, thereby improving the wearing experience of the user.

[0084] Alternatively, if Figure 8 and Fig. 9 As shown, the host module 1 has a length direction X, a width direction Z and a thickness direction Y which are perpendicular to each other, and the host module 1 is used to be stacked on the ear along the thickness direction Y when worn. The orthographic projection of the buffer cavity 220 on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane.

[0085] The buffer cavity 220 is arranged so that its orthographic projection on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane, that is, the free end 102 and at least a portion of the rear covering section 222 where the buffer cavity 220 is located are relatively clamped on both sides of the ear, so that excessive pressure is not applied when clamping the user's ear, thereby ensuring the fit while improving comfort.

[0086] Alternatively, if Fig. 9 and Fig.10 As shown, the host module 1 has an inner side surface IS facing the ear and an outer side surface OS away from the ear along the thickness direction Y in the wearing state, and an upper side surface US and a lower side surface LS2 connecting the inner side surface IS and the outer side surface OS, the upper side surface US faces the ear hook 2, and the upper side surface US and the lower side surface LS2 are spaced apart in the width direction Z. The covering member 22 is divided into a front covering section 221 and a rear covering section 222 by the extension plane of the upper side surface US, the first end 201 is located in the front covering section 221, the second end 202 is located in the rear covering section 222, and the buffer cavity 220 is opened in the rear covering section 222.

[0087] The ear hook 2 is arc-shaped and surrounds the main module 1 to position and fix the main module 1 relative to the user's ear when the user wears it. The size and width of each person's ear are different. The rear covering section 222 arranged opposite to the free end 102 has a larger deformation range due to the buffer cavity 220, so that it can better fit the user's ear when clamping the user's ear, increase the contact area between the rear covering section 222 and the ear, and will not apply excessive pressure to cause discomfort to the user, thereby effectively improving the user's experience.

[0088] Furthermore, if Fig. 9As shown, the dimension T5 of the buffer cavity 220 in the width direction Z is greater than the dimension T2 of the host module 1 in the width direction Z.

[0089] The buffer cavity 220 is set to have a dimension T5 in the width direction Z that is larger than the dimension T2 of the main module 1 in the width direction Z, so that the buffer cavity 220 has sufficient deformation space to allow the rear covering section 222 to be easily deformed, so that the rear covering section 222 can better fit the structure of the ear when clamping the user's ear, and it is also more convenient for the user to adjust the wearing.

[0090] Alternatively, if Fig. 9 As shown, the covering member 22 includes a front covering section 221 and a rear covering section 222. The front covering section 221 covers the elastic skeleton 21. The front covering section 221 and the rear covering section 222 are connected in sequence in the extension direction. The rear covering section 222 does not cover the elastic skeleton 21. The buffer cavity 220 is formed in the rear covering section 222.

[0091] The rigidity of the elastic skeleton 21 can be greater than the rigidity of the covering member 22, so that the elastic skeleton 21 can support and maintain the relative shape of the ear hook 2, and the front covering section 221 is covered on the elastic skeleton 21, so that the user's ear does not directly contact the elastic skeleton 21, while maintaining the relative shape of the ear hook 2, protecting the user's ear and improving the user's comfort. In addition, the rear covering section 222 that clamps the ear together with the free end 102 does not cover the elastic skeleton 21, that is, the rear covering section 222 can be located downstream of the elastic support member in the extension direction from the first end 201 to the second end 202, so that the rear covering section 222 is more likely to undergo elastic deformation relative to the front covering section 221, thereby increasing the comfort when fitting with the user's ear. On this basis, the buffer cavity 220 is formed in the rear covering section 222, so that the rear covering section 222 has a larger elastic range and can achieve a larger elastic deformation to adapt to different ear widths, thereby improving the scope of application and the sense of use of the earphone 100. Optionally, the material of the covering 22 may include elastic non-metallic materials such as silicone or rubber, and the material of the elastic skeleton 21 may include metal materials or non-metallic materials, such as titanium wire, steel wire or elastic plastic parts, etc., which are not limited here.

[0092] Alternatively, if Fig. 9 As shown, the ear hook 2 includes a fixing block 23, which is fixedly disposed at one end of the elastic skeleton 21 close to the second end 202, the front covering section 221 covers the fixing block 23, and the extension length D2 of the rear covering section 222 along the extension direction is greater than the extension length D4 of the fixing block 23 along the extension direction.

[0093] The fixing block 23 is fixedly disposed at one end of the elastic skeleton 21 close to the second end 202, and the front covering section 221 covers the fixing block 23, thereby improving the stability of the fixing between the front covering section 221 and the elastic skeleton 21. The extension length D2 of the rear covering section 222 along the extension direction is greater than the extension length D4 of the fixing block 23 along the extension direction, so that the rear covering section 222 has a larger extension length, which can provide sufficient contact area when worn by the user, thereby ensuring the wearing comfort of the user. Since the rear covering section 222 and the front covering section 221 may be relatively bent when the ear hook 2 undergoes elastic deformation, the setting of the fixing block 23 can effectively reduce the possibility of the elastic skeleton 21 piercing the rear covering section 222, thereby increasing the service life of the earphone 100.

[0094] Optionally, the ratio of the extension length D2 of the rear covering section 222 along the extension direction to the extension length D1 of the front covering section 221 along the extension direction is greater than or equal to one-fifth and less than or equal to one-half, so that the rear covering section 222 has a sufficient contact area with the user's ear when the earphone 100 is worn, and the elastic skeleton 21 covered by the front covering section 221 can provide sufficient supporting strength to maintain the relative shape of the ear hook 2, thereby improving the aesthetics and service life of the earphone 100.

[0095] Optionally, the extension length D1 of the front covering section 221 along the extension direction is 50-70 mm. If the value is too small, it will cause a large squeeze on the user's ears when worn, and the wearing comfort is not high. If the value is too large, when the user wears the earphone 100, the ear hook 2 cannot clamp the ear well, resulting in an unstable wearing.

[0096] Optionally, the extension length D2 of the rear covering section 222 is 10 to 30 mm. Within this length range, the ear hook 2 can be both comfortable and aesthetically pleasing, thereby improving the user's sense of use. If the value is too large, it may exceed the user's ear area when worn, thereby adversely affecting the convenience and aesthetics of use. If the value is too small, the area and length of the user's ear when worn are too small, and the ear cannot be clamped well, resulting in unstable wearing.

[0097] Alternatively, if Fig.11a and Fig.12 As shown, the ear hook 2 also includes a connector 24, which is fixedly disposed at one end of the elastic frame 21 close to the first end 201, and the connector 24 is plugged and fixed with the host module 1. The ear hook 2 is plugged and fixed with the host module 1 through the connector 24, which effectively improves the connection stability between the ear hook 2 and the host module 1 and facilitates assembly and disassembly.

[0098] Alternatively, if Fig.13As shown, the buffer cavity 220 is closed and formed inside the covering member 22. The closed buffer cavity 220 can effectively prevent impurities such as dust, grease, etc. from entering the buffer cavity 220 and damaging the buffer cavity 220, thereby effectively improving the service life of the covering member 22.

[0099] Alternatively, if Figure 8 As shown, the buffer cavity 220 is arranged in a hole shape or a groove shape, so as to better adapt to the elastic deformation of the covering member 22 and improve the wearing comfort of the user. In some embodiments, the buffer cavity 220 is arranged in a hole shape and penetrates the covering member 22 along the thickness direction Y. In other embodiments, the buffer cavity 220 is arranged in a long and curved through-hole shape, and the curvature direction of the buffer cavity 220 matches the curvature direction of the portion of the covering member 22 where the buffer cavity 220 is opened.

[0100] Alternatively, if Fig.14 As shown, the number of the buffer cavities 220 is at least two, and at least two buffer cavities 220 are spaced apart along the extension direction of the ear hook 2, so that the covering part 22 has a sufficient elastic range, which improves the wearing comfort of the user while effectively reducing the possibility of damage due to the excessive width of the user's ear, thereby improving the service life of the ear hook 2.

[0101] Alternatively, if Fig.11a As shown, the ear hook 2 also includes a filling piece 25, the hardness of which is less than that of the covering piece 22. The filling piece 25 is arranged in the buffer cavity 220, so as to provide certain support for the covering piece 22 without affecting the elastic deformation of the covering piece 22, thereby improving the service life of the covering piece 22 and thus improving the service life of the ear hook 2.

[0102] Optionally, the covering member 22 has an inner side facing the host module 1 and an outer side facing away from the inner side, and the inner side is arranged closer to the buffer cavity 220 than the outer side. The inner side of the covering member 22 is the side in contact with the ear of the user, and the buffer cavity 220 is closer to the inner side, so that the covering member 22 has a better fit and softness when worn by the user, thereby improving the user's comfort.

[0103] In the above mentioned Fig. 9 , Fig.13 In the examples shown in FIG. 1 and FIG. 2 , the elastic skeleton 21 and the buffer cavity 220 are arranged spaced apart or adjacent to each other in the extension direction of the ear hook 2. Fig.15a and Fig.15bIn the example shown, the elastic skeleton 21 and the buffer cavity 220 are spaced apart in the radial direction of the elastic skeleton 21. Specifically, the elastic skeleton 21 has a preset radial direction perpendicular to the extension direction of the elastic skeleton 21 and passing through the buffer cavity 220, and the buffer cavity 220 is spaced apart from the elastic skeleton 21 in the preset radial direction. In this way, on the basis of the buffer cavity 220 providing wearing comfort, the elastic skeleton 21 can provide better support strength at the position of the buffer cavity 220, thereby providing higher wearing stability.

[0104] Specifically, the buffer cavity 220 is closer to the host module 1 in the preset radial direction than the elastic skeleton 21, so that the buffer cavity 220 is closer to the ear when worn. Through the above arrangement, the buffer cavity 220 can provide elastic buffering when fitting the user's ear, so that it has better fit and softness, and improves wearing comfort.

[0105] Specifically, the covering member 22 includes a first covering portion 2201 and a second covering portion 2202 located on both sides of the buffer cavity 220 along a preset radial direction; the first covering portion 2201 and the second covering portion 2202 are arranged at intervals to form the buffer cavity 220, and the first covering portion 2201 is closer to the host module 1 than the second covering portion 2202, so as to contact the ear. In this way, the first covering portion 2201 is further away from the elastic skeleton 21, and the buffer cavity 220 provides a larger space for the deformation of the first covering portion 2201, thereby enabling the first covering portion 2201 to fit the ear more effectively and provide a softer fit, thereby effectively improving the wearing comfort.

[0106] like Fig.15a In an example shown, the elastic skeleton 21 can be inserted into the second covering portion 2202. Optionally, the elastic skeleton 21 extends from the first end 201 of the ear hook 2 to the second end 202 of the ear hook 2. This can provide a more complete and stronger support for the ear hook 2, thereby effectively improving the wearing stability. In addition, the elastic skeleton 21 extends from the first end 201 of the ear hook 2 to the second end 202 of the ear hook 2, and it is not easy to puncture the covering 22 when the covering 22 is bent, thereby improving the service life. Optionally, the buffer cavity 220 is closer to the second end 202 of the ear hook 2 between the first end 201 and the second end 202 of the ear hook 2.

[0107] In some embodiments, the elastic skeleton 21 further extends to the top of the buffer cavity 220 (i.e., the top of the portion of the buffer cavity 220 close to the second end 202 of the ear hook 2) in the direction of extension of the ear hook 2 from its first end 201 to the second end 202. That is, the elastic skeleton 21 can extend between the end positions of the buffer cavity 220 and the second end 202. Such a setting can provide better support. In other embodiments, the fixing block 23 can be connected to one end of the elastic skeleton 21 extending to the second end 202 of the ear hook 2, and the fixing block 23 bends and extends from the elastic skeleton 21 to one side of the buffer cavity 220, and bends and extends to the top of the buffer cavity 220 (i.e., the top of the portion of the buffer cavity 220 close to the second end 202 of the ear hook 2) in the direction of extension of the ear hook 2 from its first end 201 to the second end 202. That is, the fixing block 23 can extend between the end positions of the buffer cavity 220 and the second end 202. Such a setting can not only provide better support, but also make the covering 22 not easily punctured by the elastic skeleton 21.

[0108] In some embodiments, the end of the elastic skeleton 21 close to the second end 202 is inserted into the fixing block 23, and the circumferential dimension of the end of the fixing block 23 away from the elastic skeleton 21 is larger than the circumferential dimension of the end of the fixing block 23 plugged with the elastic skeleton 21. By inserting the elastic skeleton 21 into the fixing block 23 to achieve the connection between the elastic skeleton 21 and the fixing block 23, it is helpful to improve the connection stability between the two, and will not affect the support provided by the elastic skeleton 21 for the ear hook 2. The circumferential dimension of the end of the fixing block 23 away from the elastic skeleton 21 is larger than the circumferential dimension of the end plugged with the elastic skeleton 21, which helps to reduce the difficulty of the production process of the fixing block 23 while realizing the bending and extension of the fixing block 23, and is helpful to improve the strength and service life of the fixing block 23. The fixing block 23 and the covering member 22 can also have a larger contact area, which is helpful to reduce the processing difficulty of the ear hook 2 and improve the service life of the ear hook 2.

[0109] Alternatively, if Fig.11b and Fig.15a As shown, the ear hook 2 is provided with a first positioning hole 223, and the fixing block 23 is provided with a second positioning hole 231. The second positioning hole 231 is located at the end of the fixing block 23 away from the elastic frame 21, and the first positioning hole 223 and the second positioning hole 231 are arranged opposite to each other. The first positioning hole 223 and the second positioning hole 231 arranged opposite to each other can allow an external positioning device to position the fixing block 23 through the first positioning hole 223, so that the shape and position dimensions of the various components of the ear hook 2 are more accurate, which is conducive to improving the yield rate of the ear hook 2. And on the basis that the circumferential dimension of the end of the fixing block 23 away from the elastic frame 21 is larger than the circumferential dimension of the plugged end, the aperture of the second positioning hole 231 can also be relatively increased, which is more convenient for the operation and alignment of the external positioning device.

[0110] In some embodiments, such as Fig.15a As shown, one end of the elastic skeleton 21 close to the first end 201 is inserted into the connector 24, and the extension direction of the end of the elastic skeleton 21 close to the first end 201 intersects with the extension direction of the connector 24. Such a setting can simultaneously achieve a stable connection between the connector 24 and the host module 1 and a stable connection between the elastic skeleton 21 and the connector 24, which is beneficial to improving the connection stability between the elastic skeleton 21 and the connector 24, and is beneficial to improving the connection stability between the ear hook 2 and the host module 1.

[0111] Alternatively, if Fig.14 and Fig.15a As shown, the host module 1 has a length direction X, a width direction Z and a thickness direction Y which are perpendicular to each other. The host module 1 is used to be stacked on the ear along the thickness direction Y in the wearing state. The extension direction of the end of the elastic skeleton 21 close to the first end 201 and the length direction X have a first angle Q1 toward the ear hook 2, and the extension direction of the connector 24 and the length direction X have a second angle Q2 toward the ear hook 2, and the first angle Q1 is smaller than the second angle Q2. By setting the first angle Q1 and the second angle Q2 to two angles of different sizes, the elastic skeleton 21 and the connector 24 can be crossed with each other, and by reasonably setting the angle sizes of the first angle Q1 and the second angle Q2, while ensuring the connection stability between the connector 24 and the host module 1, the end of the elastic skeleton 21 connected to the connector 24 is closer to the center of the cross section of the ear hook 2, which is more conducive to the elastic skeleton 21 providing good support for the ear hook 2, thereby improving the use feeling and service life of the earphone 100. Optionally, the first angle Q1 is 70° to 110°, for example, 80°, 85°, 90°, 95°, 100°, etc., and the second angle Q2 is 90° to 130°, for example, 100°, 105°, 110°, 115°, 120°, etc.

[0112] like Fig.15bIn another example shown, the elastic skeleton 21 can extend to the second covering portion 2202. Optionally, the ear hook 2 includes a fixing block 23, which is arranged at one end of the elastic skeleton 21 close to the second end 202, and the covering member 22 is covered on the fixing block 23. The fixing block 23 is located on the side of the buffer cavity 220 away from the main module 1, that is, the fixing block 23 can be located in the second covering portion 2202. Through such a configuration, the side of the buffer cavity 220 close to the main module 1 can increase the fitting area with the user's ear through deformation when worn, reduce the pressure on the ear, and can fit the user's ear more comfortably, which improves the wearing comfort on the one hand, and on the other hand, such deformation buffer can achieve elastic fit to the human ear, thereby enhancing the wearing stability. Moreover, the fixed block 23 and the part of the elastic skeleton 21 located on the side of the buffer cavity 220 away from the host module 1 can enhance the support strength of the ear hook 2 without affecting the deformation of the buffer cavity 220, and can make the buffer cavity 220 produce a more stable deformation, thereby ensuring the fit comfort and wearing stability with the user's ear. Furthermore, the fixed block 23 can reduce the possibility of the elastic skeleton 21 piercing the second covering part 2202, and improve the stability and reliability of the covering part 22.

[0113] Optionally, the fixing block 23 is located between the two ends of the buffer cavity 220 along the extension direction of the ear hook 2, and is closer to the end of the buffer cavity 220 close to the second end 102. In this way, the buffer cavity 220 can be more surrounded in the extension direction of the ear hook 2, which can effectively provide stronger support for the buffer cavity 220 to deform more and better fit the ear, and can also provide stronger support for the entire ear hook 2, ensuring the support performance of the entire ear hook 2.

[0114] In order to improve the wearing comfort of the ear hook 2, see the second example structure of the ear hook 2 as follows:

[0115] like Fig.16 As shown, the earphone 100 may include a host module 1 and an ear hook 2. The ear hook 2 is connected to the host module 1. The ear hook 2 includes a connecting body 20 and an elastic buffer 26, the connecting body 20 is connected to the host module 1, and the elastic buffer 26 is connected to the connecting body 20. The connecting body 20 forms a first portion of the outer surface of the ear hook 2, and the elastic buffer 26 forms a second portion of the outer surface of the ear hook 2, and at least part of the second portion of the outer surface faces the host module 1. The hardness of the elastic buffer 26 is less than the hardness of the connecting body 20.

[0116] By providing an ear hook 2 including a connecting body 20 and an elastic buffer 26, the elastic buffer 26 has a certain elastic limit and can be elastically deformed within its elastic limit, so that when a user wears the headset 100, the ear hook 2 can be elastically deformed to fit the ear, effectively improving the wearing comfort and stability. The hardness of the elastic buffer 26 is less than the hardness of the connecting body 20, and at least a portion of the outer surface of the second part of the elastic buffer 26 facing the host module 1 can directly contact the ear when the user wears the headset 100, while the connecting body 20 with a relatively high hardness plays a supporting role, ensuring the aesthetics of the ear hook 2 while effectively improving the wearing comfort of the user.

[0117] Optionally, the elastic buffer portion 26 is detachably connected to the connecting body 20. By setting the elastic buffer portion 26 and the connecting body 20 as two detachably connected parts, production and assembly are facilitated, and when a component is damaged, it can be replaced separately, thereby improving user convenience and the service life of the headset 100.

[0118] Optionally, the elastic buffer portion 26 and the connecting body 20 can be slidably connected to facilitate installation and disassembly between the elastic buffer portion 26 and the connecting body 20, thereby improving the assembly efficiency and disassembly efficiency of the ear hook 2, and facilitating the subsequent separate replacement of the elastic buffer portion 26 or the connecting body 20.

[0119] In some embodiments, Fig.17 As shown, the elastic buffer portion 26 is provided with a sliding edge 261, and the connecting body 20 is provided with a sliding groove 203. The sliding edge 261 can be slidably embedded in the sliding groove 203, which effectively fixes the elastic buffer portion 26 and the connecting body 20 and facilitates installation and disassembly.

[0120] In some embodiments, the elastic buffer portion 26 is bonded or magnetically connected to the connection body 20. The bonding and magnetic connection structures are simple, easy to install and disassemble, and no additional structure is required to achieve the connection between the elastic buffer portion 26 and the connection body 20, effectively saving production costs and reducing subsequent maintenance costs.

[0121] Alternatively, if Fig.16 As shown, the host module 1 includes a connecting end 103 connected to one end of the ear hook 2 and a free end 102 away from the connecting end 103. The host module 1 is used to be overlapped on the user's ear when worn, and at least part of the outer surface of the second part is arranged opposite to the free end 102.

[0122] The connection end 103 of the host module 1 is connected to the ear hook 2, and the free end 102 and at least a portion of the outer surface of the second portion of the elastic buffer portion 26 are arranged relative to each other, so that when the user wears the earphone 100, the free end 102 and at least a portion of the outer surface of the second portion are clamped on both sides of the ear, and the elastic buffer portion 26 can adaptively undergo elastic deformation to facilitate wearing by users with different ear sizes, while ensuring the wearing stability of the earphone 100, the adaptability of the earphone 100 is effectively improved.

[0123] Alternatively, if Fig.18 and Fig.19 As shown, the extension length D3 of the elastic buffer portion 26 along the extension direction of the ear hook 2 is greater than or equal to one third of the extension length D0 of the ear hook 2 along the extension direction. The elastic buffer portion 26 has a sufficient contact length with the user's ear when worn by the user, thereby increasing the contact area between the elastic buffer portion 26 and the ear, thereby better fitting the ear and improving the user's wearing comfort.

[0124] Alternatively, if Fig.17 As shown, in a partial section along the extension direction of the ear hook 2, an elastic buffer portion 26 and a connecting body 20 can be simultaneously provided in the same cross-section perpendicular to the extension direction of the ear hook 2, and the ratio of the circumferential dimension R1 of the outer edge of the elastic buffer portion 26 to the circumferential dimension R2 of the outer edge of the connecting body 20 is greater than or equal to 0.2 and less than 1, so that while the connecting body 20 provides sufficient support for the ear hook 2 to ensure the relative shape of the ear hook 2, the elastic buffer portion 26 with lower hardness can reduce the discomfort caused by the pressure applied by the ear hook 2 when the user wears it, thereby improving the wearing comfort of the user.

[0125] Alternatively, if Fig.16 and Fig.18 As shown, the host module 1 has a length direction X, a width direction Z and a thickness direction Y that are perpendicular to each other, and the host module 1 is used to be stacked on the ear of the user along the thickness direction Y in the wearing state. The orthographic projection of the elastic buffer portion 26 on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane, that is, the orthographic projection of the elastic buffer portion 26 on the reference plane parallel to the width direction Z and the thickness direction Y partially overlaps with the orthographic projection of the free end 102 on the reference plane.

[0126] The elastic buffer portion 26 is arranged so that its orthographic projection on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane, that is, the free end 102 and at least a portion of the elastic buffer portion 26 are relatively clamped on both sides of the ear, so that when clamping the user's ear, excessive pressure is not applied while ensuring stability, thereby ensuring fit and improving comfort.

[0127] Furthermore, if Fig.16 and Fig.18 As shown, the elastic buffer portion 26 is closer to the host module 1 than the connecting body 20, thereby increasing the contact area between the elastic buffer portion 26 with lower hardness and the user's ear, and can better fit the structure of the ear when clamping the user's ear, and the comfort is higher. In some embodiments, the elastic buffer portion 26 can be closer to the host module 1 than the connecting body 20 in the radial direction of the ear hook 2, wherein the radial direction of the ear hook 2 is perpendicular to the extension direction of the ear hook 2.

[0128] Furthermore, if Fig.16 , Fig.18 and Fig.19 As shown, the elastic buffer portion 26 and the connecting body 20 are spliced, so that when the ear hook 2 is hung on the ear of the user, the contact area between the elastic buffer portion 26 with lower hardness and the ear of the user is increased, and the contact area between the connecting body 20 with higher hardness and the ear of the user is reduced, thereby improving the user's comfort. In some embodiments, the elastic buffer portion 26 and the connecting body 20 can be spliced ​​with each other in the normal direction F of the outer contour of the ear hook 2 and the extension direction of the ear hook 2, for example, wherein the normal direction F of the outer contour of the ear hook 2 is a direction perpendicular to the outer contour of the ear hook 2. The splicing of the elastic buffer portion 26 and the connecting body 20 in the normal direction F of the outer contour of the ear hook 2 facilitates positioning and installation, effectively reducing the difficulty of assembly.

[0129] Alternatively, if Fig.16 , Fig.18 and Fig.19 As shown, the ear hook 2 has a first end 201 and a second end 202 that are arranged opposite to each other, the first end 201 is connected to the host module 1, and the second end 202 is located at the elastic buffer portion 26, and the elastic buffer portion 26 is closed along the circumferential direction at the second end 202. The part of the elastic buffer portion 26 that forms the second end 202 is located below the connection body 20 in the direction from the first end 201 to the second end 202 of the ear hook 2, and the other part of the elastic buffer portion 26 is located on the side of the connection body 20 facing the host module 1. The splicing of the elastic buffer portion 26 and the connection body 20 can reduce the difficulty of assembly and improve the stability and reliability of the connection. A part of the elastic buffer 26 is arranged to be located on the side of the connection body 20 facing the host module 1, so that the elastic buffer 26 contacts the user's ear more than the connection body 20, thereby improving the user's wearing comfort, and the part of the elastic buffer 26 that forms the second end 202 is located below the connection body 20 in the direction of the ear hook 2 from the first end 201 to the second end 202, which is conducive to increasing the contact area between the elastic buffer 26 and the ear, and improving the wearing stability while ensuring the wearing comfort. The elastic buffer 26 is closed along the circumferential direction at the second end 202, which can reduce the entry of foreign impurities into the elastic buffer 26, avoid damage to the elastic buffer 26, and increase the service life of the elastic buffer 26.

[0130] Furthermore, if Figures 16 to 19 As shown, the first end 201 is connected to the host module 1, and the circumferential dimension R1 of the elastic buffer portion 26 gradually increases or increases in a stepwise manner from the first end 201 to the second end 202. Since the first end 201 is connected to the host module 1, the first end 201 needs a higher hardness to ensure the connection stability and reliability of the ear hook 2, and needs to provide sufficient supporting force to maintain the relative position between the ear hook 2 and the host module 1, so as to ensure that the user can wear and use the earphone 100 normally. Therefore, the elastic buffer portion 26 with lower hardness has a smaller circumferential dimension R1 at a position close to the first end 201, and the circumferential dimension R1 of the elastic buffer portion 26 gradually increases or increases in a stepwise manner from the first end 201 to the second end 202, which can effectively improve the user's comfort.

[0131] Alternatively, if Figures 16 to 19 As shown, the connecting body 20 and the elastic buffer part 26 are sequentially connected along the extension direction of the ear hook 2, and the second end 202 is located at the elastic buffer part 26. The elastic buffer part 26 and the connecting body 20 can smoothly transition in the extension direction of the ear hook 2 at the ends connected to each other, thereby ensuring the wearing comfort while improving the aesthetics of the ear hook 2 and the stability of the connection. In some embodiments, the circumferential dimension R2 of the connecting body 20 gradually decreases from the end connected to the elastic buffer part 26 toward the first end 201. In some embodiments, the circumferential dimension R2 of the connecting body 20 first gradually decreases and then gradually increases from the end connected to the elastic buffer part 26 toward the first end 201. In other embodiments, the circumferential dimension R2 of the connecting body 20 at the end connected to the elastic buffer part 26 is the maximum circumferential dimension of the connecting body 20.

[0132] Alternatively, if Fig. 20 As shown, the connecting body 20 includes an elastic skeleton 21 and a covering 22, the covering 22 covers at least a part of the elastic skeleton 21, and the elastic buffer part 26 is connected to the covering 22, the hardness of the elastic buffer part 26 is less than the hardness of the covering 22, and the hardness of the covering 22 is less than the hardness of the elastic skeleton 21. The elastic skeleton 21 provides the main support to maintain the relative shape of the ear hook 2 to avoid the user's inability to use it normally due to the deformation of the ear hook 2, and the covering 22 and the elastic buffer part 26 with successively decreasing hardness can avoid the elastic skeleton 21 with higher hardness from directly contacting the user's ear, thereby improving the wearing comfort of the user. Optionally, a buffer cavity 220 is provided in the ear hook 2, for example, it can be provided in the covering 22, or in the elastic buffer part 26, or in the covering 22 and the elastic buffer part 26, so as to increase its softness and deformable range and improve the user's comfort. For details, please refer to the description of the above embodiment.

[0133] In some embodiments, the covering 22 covers a portion of the elastic skeleton 21, and the elastic buffer portion 26 covers another portion of the elastic skeleton 21. The elastic skeleton 21 serves as a support and connecting bridge for the ear hook 2, thereby improving the connection stability and reliability of the ear hook 2.

[0134] In some embodiments, the covering 22 and the elastic buffer portion 26 are connected sequentially in the extension direction. The elastic buffer portion 26 does not cover the elastic skeleton 21, but is located downstream of the elastic skeleton 21 in the extension direction of the ear hook 2, so that the softness and deformation range of the elastic buffer portion 26 will not be affected, thereby maximizing the user comfort and the applicability of the earphone 100.

[0135] In order to improve the wearing comfort of the ear hook 2, see the third example structure of the ear hook 2 as follows:

[0136] Combination Figure 21 to Figure 24 As shown, the ear hook 2 has a first end 201 and a second end 202 that are arranged opposite to each other, and the first end 201 is connected to the host module 1. The ear hook 2 is used to be hung on the ear 500 of the user. Among them, the ear hook 2 includes an elastic frame 21, a covering 22 and a fixing block 23, and the elastic frame 21 is extended along the extension direction from the first end 201 to the second end 202. The covering 22 includes a front covering section 221 and a rear covering section 222, and the front covering section 221 and the rear covering section 222 are connected to each other in the extension direction. The fixing block 23 is arranged at an end of the elastic frame 21 away from the first end 201, and the front covering section 221 covers the elastic frame 21 and the fixing block 23. The rear covering section 222 does not cover the elastic frame 21 and the fixing block 23, but is located downstream of the fixing block 23 in the extension direction. The extension length D2 of the rear covering section 222 along the extension direction is greater than or equal to the extension length D4 of the fixing block 23 along the extension direction. Such a configuration can prevent the elastic skeleton 21 from piercing the covering member 22, making it easier to process and shape, and can effectively improve the processing accuracy.

[0137] The host module 1 is used to play sounds. The ear hook 2 can be connected to the host module 1 through the first end 201, so that the host module 1 can be kept close to or in contact with the user's ear 500. The elastic skeleton 21 can support the covering 22 in the ear hook 2. The elastic skeleton 21 can be deformed to a certain extent. The covering 22 can cover the elastic skeleton 21, and can be deformed accordingly with the deformation of the elastic skeleton 21. In this way, the user can adjust the shape of the ear hook 2 by adjusting the shape of the elastic skeleton 21, so that the ear hook 2 can better adapt to the shape of the user's ear 500, improve the user's wearing comfort, and make the earphone 100 more stable to wear.

[0138] By setting the rear covering section 222 on the basis of the front covering section 221, and setting the extension length D2 of the rear covering section 222 along the extension direction to be greater than or equal to the extension length D4 of the fixing block 23 along the extension direction, it can be ensured that the rear covering section 222 has a sufficient length along the extension direction, and the length of the ear hook 2 along the extension direction can be increased, thereby improving the wearing comfort and stability of the earphone 100. By setting the rear covering section 222 not to cover the elastic skeleton 21 and the fixing block 23, the rear covering section 222 is not supported by the elastic skeleton 21 and the fixing block 23, and the force of the rear covering section 222 on the human ear can be reduced, thereby improving the wearing comfort of the user. At the same time, the elastic skeleton 21 is not set in the rear covering section 222, which can reduce the material used for the elastic skeleton 21 and reduce the cost.

[0139] If the fixing block 23 is not provided, when the rear covering section 222 is relatively elastically bent relative to the front covering section 221, there is a risk that the titanium wire will pierce the covering member 22 (e.g., the rear covering section 222) of the elastic skeleton 21. Here, by providing the fixing block 23 at the end of the elastic skeleton 21 away from the first end 201, the direct contact between the end of the elastic skeleton 21 away from the first end 201 and the rear covering section when the rear covering section 222 is bent relative to the front covering section 221 can be reduced, thereby reducing the risk of the end of the elastic skeleton 21 away from the first end 201 piercing the covering member 22 (e.g., the rear covering section 222), and reducing the wearing discomfort caused by the end of the elastic skeleton 21 away from the first end 201.

[0140] Furthermore, the radial dimension of the fixing block 23 perpendicular to the extension direction may be greater than the radial dimension of the elastic skeleton 21 at one end away from the first end 201 perpendicular to the extension direction. In other words, the circumferential dimension of the fixing block 23 may be greater than the circumferential dimension of the elastic skeleton 21 .

[0141] Optionally, the covering member 22 is made of silicone, plastic or rubber.

[0142] Combination Fig. 22 In some embodiments, the extension length D2 of the rear covering section 222 along the extension direction is 10-25 mm.

[0143] According to the large-scale model data of the human auricle, since the front covering section 221 is closer to the hanging position at the rear side of the ear tip (for the ear hook 2 to hang), the further it extends toward the second end 202 of the ear hook 2, the greater the deviation between the ear hook 2 and the natural contour of the human ear may be. Therefore, the further back the ear hook 2 is, the greater the deformation capacity is needed. By setting the extension length D2 of the rear covering section 222 along the extension direction to be greater than or equal to 10 mm, it can be ensured that the rear covering section 222 has sufficient length and deformation capacity along the extension direction, and the shape stability (fatigue resistance) and comfort (adaptation to a wider range of people) performance of the ear hook 2 can be well taken into account. In addition, when the rear covering section 222 is set in this way, it can be ensured that the fixing block 23 will not puncture the covering 22 of the rear covering section 222.

[0144] By setting the extension length D2 of the rear covering section 222 along the extension direction to be less than or equal to 25 mm, the appearance structure of the earphone 100 can be made more concise. Furthermore, the extension length D2 of the rear covering section 222 along the extension direction is 12-25 mm. For example, the extension length D2 of the rear covering section 222 along the extension direction is 12 mm, 15 mm, 18 mm, 20 mm or 22 mm.

[0145] Optionally, an extension length D1 of the front covering section 221 along the extension direction is 35-80 mm.

[0146] By setting the extension length D1 of the front covering section 221 along the extension direction to be greater than or equal to 35 mm, it can be ensured that the front covering section 221 has sufficient length along the extension direction, thereby improving the wearing stability of the earphone 100. By setting the extension length D1 of the front covering section 221 along the extension direction to be less than or equal to 70 mm, the force exerted by the front covering section 221 on the human ear can be reduced, thereby improving the wearing comfort of the user, and at the same time, the material used for the elastic skeleton 21 can be reduced, thereby reducing the cost. For example, the extension length D1 of the front covering section 221 along the extension direction is 40 mm, 45 mm, 48 mm, 50 mm, 55 mm, 60 mm, 65 mm, or 68 mm.

[0147] Optionally, the extension length D4 of the fixing block 23 along the extension direction is 6-15 mm. For example, the extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 may be 8 mm, 10 mm or 12 mm. With such a configuration, on the one hand, the fixing block 23 can have a sufficient and reasonable length to cover the end of the elastic skeleton 21, making it more difficult for the elastic skeleton 21 to pierce the covering 22, thereby effectively reducing the probability of the end of the elastic skeleton 21 piercing the covering 22, and also improving the fixing effect between the elastic skeleton 21 and the fixing block 23. On the other hand, the above-mentioned size setting can achieve a better fixing effect between the covering 22 and the fixing block 23, so that the covering 22 better wraps the fixing block 23, thereby making the fixing effect between the fixing block 23 and the elastic skeleton 21 better.

[0148] Combination Fig. 22 In some embodiments, the ratio of the extension length D1 of the front covering section 221 along the extension direction to the extension length D2 of the rear covering section 222 along the extension direction is greater than or equal to 2 and less than or equal to 4.5.

[0149] According to the large model data of the human auricle, since the front covering section 221 is closer to the hanging position at the rear side of the ear tip (for hanging the ear hook 2), the further it extends to the second end 202 of the ear hook 2, the greater the deviation between the ear hook 2 and the natural contour of the human ear may be. Therefore, the further back the ear hook 2 is, the greater the deformation ability is required. Under the combination of the sizes of the front covering section 221 and the rear covering section 222, the front covering section 221 can serve as the deformation arm of the rear covering section 222 so that the rear covering section 222 obtains a higher deformation ability, which can well take into account the shape stability (fatigue resistance) and comfort (adaptability to a wider range of people) performance of the ear hook 2.

[0150] For example, the ratio of the extension length D1 of the front cladding section 221 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 2.2-2.5, 2.6-2.8 or 3.0-3.5. Further, the ratio of the extension length D1 of the front cladding section 221 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 3.3-3.4.

[0151] If the ratio of the extension length D1 of the front covering section 221 along the extension direction to the extension length D2 of the rear covering section 222 along the extension direction is less than 2, the wearing stability of the ear hook 2 is low. If the ratio of the extension length D1 of the front covering section 221 along the extension direction to the extension length D2 of the rear covering section 222 along the extension direction is greater than 4, the wearing comfort of the ear hook 2 is poor. By setting the ratio of the extension length D1 of the front covering section 221 along the extension direction to the extension length D2 of the rear covering section 222 along the extension direction to be greater than or equal to 2 and less than or equal to 4.5, the ear hook 2 can have both good wearing stability and comfort.

[0152] Combination Fig.23 In some embodiments, one end of the elastic skeleton 21 away from the first end 201 is inserted into the fixing block 23 .

[0153] By setting the end of the elastic skeleton 21 away from the first end 201 to be inserted into the fixing block 23, the fixing block 23 can cover the end of the elastic skeleton 21 away from the first end 201, which is beneficial for the fixing block 23 to be stably fixed to the end of the elastic skeleton 21 away from the first end 201, thereby reducing the damage of the end of the elastic skeleton 21 away from the first end 201 to the covering part 22 and reducing the wearing discomfort caused by the end of the elastic skeleton 21 away from the first end 201.

[0154] Combination Fig.23 In some embodiments, the connection between the end surface of the fixing block 23 facing the rear cladding section 222 and the peripheral side surface of the fixing block 23 is chamfered or set as a curved surface. For example, the connection between the end surface of the fixing block 23 facing the rear cladding section 222 and the peripheral side surface of the fixing block 23 is a curved surface transition.

[0155] The front covering section 221 has a stronger supporting effect on the user's ear 500, while the rear covering section 222 has a weaker supporting effect on the user's ear 500. By chamfering or setting the connection between the end surface of the fixing block 23 facing the rear covering section 222 and the peripheral side surface of the fixing block 23 as a curved surface, the supporting effect of the rear covering section 222 and the front covering section 221 on the user's ear 500 at the junction can be more smoothly transitioned, thereby improving the wearing comfort of the user.

[0156] Combination Fig.23 and Fig.25 In some embodiments, the front covering section 221 and / or the rear covering section 222 is provided with a first positioning hole 223 , and the fixing block 23 can be exposed through the first positioning hole 223 .

[0157] During the production process of the ear hook 2, the first positioning hole 223 can avoid the external positioning device, thereby allowing the external positioning device to position the fixing block 23 through the first positioning hole 223, thereby reducing the deformation of the elastic skeleton 21 during the production process of the ear hook 2, making the shape and position dimensions of the various components of the ear hook 2 more precise, thereby improving the quality yield of the ear hook 2.

[0158] The first positioning hole 223 provided in the front covering section 221 can be used by an external positioning device to act on the peripheral side surface of the fixing block 23 or the end surface of the fixing block 23 away from the rear covering section 222. The first positioning hole 223 provided in the rear covering section 222 can be used by an external positioning device to act on the end surface of the fixing block 23 facing the rear covering section 222. For example, the first positioning hole 223 is provided in both the front covering section 221 and the rear covering section 222, so that the external positioning device can act on different positions of the fixing block 23, which is conducive to improving the fixing effect of the positioning block.

[0159] Further, the first positioning holes 223 are provided in pairs in the front covering section 221 and / or the rear covering section 222. The two first positioning holes 223 are arranged in pairs opposite to each other, so that the opposite sides of the fixing block 23 can be exposed through the first positioning holes 223. Such arrangement facilitates the positioning of the fixing block 23 and improves the fixing effect of the fixing block 23.

[0160] Combination Fig.23 and Fig.25In some embodiments, the first positioning hole 223 is opened on the peripheral side of the front covering section 221 and / or the rear covering section 222, and a groove 224 is also opened on the peripheral side of the front covering section 221 and / or the rear covering section 222, and the first positioning hole 223 is opened at the bottom of the groove 224.

[0161] On the one hand, the groove 224 can reduce the size of the front covering section 221 and / or the rear covering section 222, and provide deformation space for the front covering section 221 and / or the rear covering section 222 to deform, so that the front covering section 221 and / or the rear covering section 222 are more easily deformed when subjected to force, which can facilitate the user to wear and improve the wearing comfort. On the other hand, the groove 224 facilitates the user to identify the earphone 100 through touch, which is conducive to the user to sense the posture and position of the earphone 100 in space through touch, so that the user can wear and use the earphone 100 correctly when not using vision.

[0162] Combination Fig.23 and Fig.25 In some embodiments, the first positioning hole 223 is located at one end of the groove 224 , and the other end of the groove 224 extends toward the second end 202 .

[0163] This arrangement is conducive to the user to simultaneously sense the second end 202 and the groove 224 through touch, making it easier for the user to sense the posture and position of the earphone 100 in space through touch. At the same time, the groove 224 is more located in the rear covering section 222, which is conducive to the deformation of the rear covering section 222.

[0164] Combination Fig.21 , Fig.23 and Figure 1 In some embodiments, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. The host module 1 is used to be stacked on the ear 500 along the thickness direction Y when worn. The first positioning hole 223 is extended along the thickness direction Y.

[0165] The covering member 22 can be coated on the elastic frame 21 by injection molding, and the first positioning hole 223 is formed in the covering member 22 by injection molding. By setting the first positioning hole 223 to extend along the thickness direction Y, during the injection molding process, the mold opening direction is consistent with the direction in which the mold is separated from the first positioning hole 223, thereby facilitating demolding of the covering member 22.

[0166] Furthermore, the first positioning hole 223 is provided on the side of the ear hook 2 facing the host module 1 in the wearing state. Such a configuration is conducive to the ear 500 shielding the first positioning hole 223 in the wearing state, thereby improving the appearance of the headset 100.

[0167] Combination Fig.23Optionally, the fixing block 23 is provided with a second positioning hole 231 , and the first positioning hole 223 and the second positioning hole 231 are arranged opposite to each other and are connected.

[0168] The second positioning hole 231 is provided to facilitate an external positioning device to position the fixing block 23 , which is beneficial to improving the fixing effect. For example, an external positioning device can be inserted into the second positioning hole 231 to position the fixing block 23 .

[0169] Furthermore, the second positioning hole 231 is a blind hole, which can facilitate demoulding during the injection molding process on one hand, and can prevent the second positioning hole 231 from penetrating the fixing block 23 on the other hand, so that the fixing block 23 can maintain a relatively high strength.

[0170] Furthermore, the second positioning holes 231 are provided in pairs. The two second positioning holes 231 in a pair are arranged opposite to each other, so that the two opposite sides of the fixing block 23 can be fixed through the second positioning holes 231. Such arrangement facilitates the positioning of the fixing block 23 and improves the fixing effect of the fixing block 23.

[0171] Combination Fig. 22 In some embodiments, the earphone 100 further includes a functional part 26a, which is detachably connected to the first positioning hole 223. Such a configuration can improve the appearance and functionality of the earphone 100. For example, the user's left ear and right ear each wear an earphone 200. The functional part 26a can be configured to detachably connect the two earphones 100 together (for example, by snapping, bonding, threading, magnetic connection, or connection through an additional fixing member, etc.), thereby reducing the risk of losing the earphone 100.

[0172] Combination Fig. 22 Further, the functional part 26a is a lanyard, which can be used to connect two earphones 100. Of course, the functional part 26a can also be an arc-shaped metal part, and two functional parts 26a can be spliced ​​to form a larger arc-shaped structure.

[0173] In some embodiments, the hardness of the fixing block 23 is greater than the hardness of the covering member 22. By setting the fixing block 23 to have a greater hardness, the protective effect of the fixing block 23 on the covering member 22 can be improved. By setting the covering member 22 to have a smaller hardness, the wearing comfort of the user can be improved.

[0174] Optionally, the material of the covering member 22 is relatively soft plastic, silicone or rubber, and the material of the fixing block 23 is relatively hard plastic or metal.

[0175] Combination Fig. 22 and Fig.23Optionally, the front covering section 221 and the rear covering section 222 are integrally formed, and the front covering section 221 is integrally covered on the outer periphery of the elastic skeleton 21 and the fixing block 23. For example, the front covering section 221 and the rear covering section 222 are integrally formed by injection molding.

[0176] Such an arrangement can make the covering member 22 have a good and uniform covering effect, and at the same time make the front covering section 221 and the rear covering section 222 stably connected.

[0177] Combination Fig. 22 In some embodiments, the host module 1 includes a connection end 103 connected to the first end 201 of the ear hook 2 and a free end 102 away from the connection end 103, and at least a portion of the rear covering section 222 is arranged opposite to the free end 102. In this way, when the earphone 100 is worn, at least a portion of the rear covering section 222 and the free end 102 are respectively located on both sides of the same position of the ear 500, and further, at least a portion of the rear covering section 222 and the free end 102 at the same position of the ear 500 exert equal force on both sides of the force arm, so as to improve wearing comfort.

[0178] Combination Fig. 22 In some embodiments, the host module 1 includes a connection end 103 connected to the first end 201 of the ear hook 2 and a free end 102 away from the connection end 103, and the fixing part is arranged opposite to the free end 102. In this way, when the earphone 100 is worn, the fixing part and the free end 102 are respectively located on both sides of the same position of the ear 500, and further, the host module 1 and the front covering section 221 exert equal force on the force arms on both sides of the ear 500 to improve the wearing stability.

[0179] Combination Fig. 22 and Figure 1 In some embodiments, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other, and the host module 1 is used to be stacked on the ear 500 along the thickness direction Y when worn. The dimension T1 of the rear covering section 222 along the width direction Z is greater than the dimension T2 of the host module 1 along the width direction Z.

[0180] Such a configuration can ensure that the rear covering section 222 has a sufficient length along the width direction Z, thereby improving the wearing comfort and stability of the earphone 100.

[0181] Combination Fig.21 and Fig. 22In some embodiments, the host module 1 has an inner side surface IS facing the ear 500 and an outer side surface OS away from the ear 500 along the thickness direction Y in the wearing state, and an upper side surface US and a lower side surface LS2 connecting the inner side surface IS and the outer side surface OS, and the upper side surface US and the lower side surface LS2 are arranged at intervals in the width direction Z. The second end 202 is located at the rear covering section 222, and the rear covering section 222 extends over the lower side surface LS2 in the width direction Z.

[0182] Such a configuration can ensure that the rear covering section 222 has a sufficient length along the width direction Z, thereby improving the wearing comfort of the earphone 100 . At the same time, it is beneficial for the ear hook 2 to have a sufficient length along the width direction Z, thereby improving the wearing stability of the earphone 100 .

[0183] Combination Fig. 22 In some embodiments, at least a portion of the fixing block 23 is located between the extension plane of the upper side US and the extension plane of the lower side LS2, and the extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 is 6-15 mm. For example, a portion of the fixing block 23 is located between the extension plane of the upper side US and the extension plane of the lower side LS2, and another portion of the fixing block 23 is located on the side of the extension plane of the upper side US close to the first end 201, and the extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 may be 8 mm, 10 mm, or 12 mm.

[0184] Such arrangement enables at least part of the fixing block 23 and the host module 1 to be located on both sides of the same position of the ear 500 when the earphone 100 is worn, and further enables at least part of the rear fixing block 23 and the host module 1 to exert equal force on both sides of the force arm at the same position of the ear 500, thereby improving the stability and support of wearing, and effectively improving the wearing comfort in cooperation with the rear covering section 222. Moreover, the fixing block 23 at one end of the elastic skeleton 21 can extend between the extension plane of the upper side US and the extension plane of the lower side LS2 and be set to the above-mentioned size, on the one hand, the elastic skeleton 21 and the fixing block 23 as a whole can have a larger force arm relative to the first end 201 of the ear hook 2, and thus can be deformed in a more labor-saving manner when worn. In other words, the pressure applied to the user's ear can be reduced while maintaining the same clamping effect, thereby improving the wearing comfort. On the other hand, it can provide better support, and enable the rear covering section 222 to be more closely attached to the human ear, further providing better wearing comfort through buffering capacity.

[0185] Combination Fig.26 In some embodiments, the rear covering section 222 is provided with a buffer cavity 220 , and at least a portion of the buffer cavity 220 is located at a portion of the rear covering section 222 that is opposite to the free end 102 .

[0186] When the earphone 100 is worn, at least part of the buffer cavity 220 and the free end 102 are located on both sides of the same position of the ear 500, further allowing at least part of the rear covering section 222 and the free end 102 to exert equal force on both sides of the force arm at the same position of the ear 500. The buffer cavity 220 can reduce the size of the rear covering section 222, provide deformation space for the deformation of the rear covering section 222, make it easier for the rear covering section 222 to deform when subjected to force to adapt to the shape of the ear 500, reduce the force on the ear 500 between the free end 102 and the rear covering section 222, make it easier for users to wear, and improve wearing comfort.

[0187] Combination Figure 1 and Fig.26 In some embodiments, the free end 102 is configured to extend into the concha cavity 502 of the ear 500 when in a worn state, the free end 102 and the rear covering section 222 are configured to clamp the ear 500 area from the front and back sides of the ear 500 area corresponding to the concha cavity 502 when in a worn state, and the buffer cavity 220 is located in the portion of the rear covering section 222 for clamping the ear 500 area.

[0188] By setting the free end 102 to extend into the concha cavity 502 of the ear 500 in the wearing state, the ear can receive the sound emitted by the earphone 100. When the earphone 100 is worn, at least part of the buffer cavity 220 and the free end 102 are respectively located at the front and rear sides of the ear 500 region corresponding to the concha cavity 502, so that the part of the rear covering section 222 used to clamp the ear 500 region and the free end 102 at the front and rear sides of the ear 500 region corresponding to the concha cavity 502 can exert equal force. The buffer cavity 220 can reduce the size of the rear covering section 222, provide deformation space for the deformation of the rear covering section 222, make the rear covering section 222 more easily deformed to adapt to the shape of the ear 500 when subjected to force, reduce the force on the ear 500 region corresponding to the concha cavity 502 between the free end 102 and the rear covering section 222, can facilitate the user to wear, and improve the wearing comfort.

[0189] Combination Fig. 22 In some embodiments, the buffer cavity 220 is arranged in the shape of a long strip through hole or a groove, and the ratio of the extension length T3 of the buffer cavity 220 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is greater than or equal to one half, and less than or equal to four fifths. For example, the ratio of the extension length T3 of the buffer cavity 220 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 0.6-0.7. For example, the ratio of the extension length T3 of the buffer cavity 220 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is one third.

[0190] Such arrangement can not only provide the buffer cavity 220 with sufficient deformation space for the rear covering section 222, but also maintain good supporting performance of the rear covering section 222. The buffer cavity 220 is arranged to facilitate tactile recognition when taking off and wearing.

[0191] Combination Fig.24 and Fig.25 In some embodiments, the ear hook 2 further includes a connector 24, which is fixedly disposed at one end of the elastic frame 21 close to the first end 201, and the connector 24 is plugged and fixed to the host module 1. The extension length T4 of the connector 24 along the extension direction is greater than the extension length D4 of the fixing block 23 along the extension direction.

[0192] By providing the connector 24, it is convenient to assemble the ear hook 2 and the host module 1. For example, the ear hook 2 and the host module 1 can be snap-connected by the connector 24. By setting the extension length T4 of the connector 24 along the extension direction to be greater than the extension length D4 of the fixing block 23 along the extension direction, it is helpful to improve the connection stability between the ear hook 2 and the host module 1. In addition, such a setting can make the shape accuracy of the outer periphery of the connector 24 close to one end of the host module 1 higher when the ear hook 2 is injection molded, so that the product consistency of the overall ear hook 2 is better.

[0193] Combination Fig. 22 , Fig.24 and Fig.25 In some embodiments, the elastic skeleton 21 is inserted into the connector 24, and the connector 24 is provided with a third positioning hole 241 on the peripheral side. The host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. The host module 1 is used to be stacked on the ear 500 along the thickness direction Y in the wearing state. The third positioning hole 241 is extended along the thickness direction Y.

[0194] By setting the third positioning hole 241, during the production process of the ear hook 2, it is convenient for an external positioning device to position the docking plug 24, thereby reducing the deformation of the elastic skeleton 21 during the production process of the ear hook 2, making the shape and position dimensions of the various components of the ear hook 2 more accurate, thereby improving the quality yield of the ear hook 2.

[0195] The connector 24 can be formed by injection molding, and the third positioning hole 241 is also formed by injection molding in the connector 24. By setting the third positioning hole 241 to extend along the thickness direction Y, during the injection molding process, the mold opening direction is consistent with the direction in which the mold is separated from the third positioning hole 241, thereby facilitating demoulding of the connector 24.

[0196] Furthermore, the third positioning hole 241 is a blind hole, which can facilitate demoulding during the injection molding process on one hand, and can prevent the third positioning hole 241 from penetrating the fixing block 23 on the other hand, so that the fixing block 23 can maintain a relatively high strength.

[0197] In some embodiments, Fig.14 and Fig.15a As shown, the host module 1 has a length direction X, a width direction Z and a thickness direction Y that are perpendicular to each other. The host module 1 is used to be stacked on the ear along the thickness direction Y when worn. The extension direction of the elastic skeleton 21 at one end close to the first end 201 has a first angle Q1 with the length direction X toward the ear hook 2, and the extension direction of the connector 24 has a second angle Q2 with the length direction X toward the ear hook 2, and the first angle Q1 is smaller than the second angle Q2.

[0198] Whether it is the headset 100 or other electronic devices 300 such as computers, mobile phones, tablet computers, etc., they are all provided with a charging interface, a data transmission interface, or both. The following is an exemplary description of exemplary contents of the interface of the electronic device 300.

[0199] like Fig. 27 As shown, the electronic device 300 may include a battery 14 and an interface circuit 310. The interface circuit 310 is coupled to the battery 14 so that an external charging device can charge the battery 14 via the interface circuit 310. The electronic device 300 may be a mobile phone, a computer, an earphone device, or the like. The external charging device may be a power bank, a charging pile, or the like that can output electrical energy to the electronic device 300 via the interface circuit 310.

[0200] In some embodiments, Figure 7 , Figure 8 as well as Fig. 27 As shown, the electronic device 300 may include a charging box 900 and an earphone 100. The charging box 900 accommodates the earphone 100 and is used to charge the earphone 100. The interface circuit 310 may be arranged in the charging box 900 so that an external charging device can charge the charging box 900 via the interface circuit 310, thereby enabling the charging box 900 to obtain electrical energy from the external charging device, and when the earphone 100 is accommodated in the charging box 900, the charging box 900 can charge it.

[0201] For example, Fig.28As shown, the interface circuit 310 may include a power receiving interface 311 and a preset thermistor 312. Among them, the power receiving interface 311 may include an identification pin A5 (B5), and the identification pin A5 (B5) may be used for the external charging device to detect the coupling state of the interface circuit 310 and the external charging device when the interface circuit 310 is coupled with the external charging device, and continuously transmit the coupling state to the external charging device, so that the external charging device can grasp the coupling state of the interface circuit 310 and the external charging device in real time, and can react in time according to the detected coupling state to avoid causing safety accidents as much as possible. In some embodiments, the external charging device can be configured to intermittently detect the coupling state of the interface circuit 310 and the external charging device, for example, the external charging device can detect the coupling state every 5s or 10s, saving energy consumption of the external charging device and the electronic device 300.

[0202] The preset thermistor 312 may be configured to change the coupling state of the interface circuit 310 detected by the external charging device as the temperature of the power receiving interface 311 changes. Fig.28 As shown, the preset thermistor 312 can be coupled to the identification pin A5 (B5). After detecting the temperature change of the power receiving interface 311, the preset thermistor 312 further changes the coupling state of the interface circuit 310 and the external charging device according to the temperature of the power receiving interface 311, and the coupling state is transmitted to the external charging device through the identification pin A5 (B5). By setting the preset thermistor 312 and the identification pin A5 (B5) connected to the preset thermistor 312 in the interface circuit 310, when the electronic device 300 is connected to the external charging device through the interface circuit 310 for charging, the external charging device can monitor the temperature of the power receiving interface 311 in time, so that the coupling state of the interface circuit 310 and the external charging device can be grasped in real time, so as to be able to make the next step response more sensitively according to the detected coupling state, so as to protect the electronic device 300 in time and avoid safety accidents as much as possible.

[0203] In some embodiments, the power receiving interface 311 may be a Type-C interface, and the identification pin A5 (B5) may be a CC (Configuration Channel) pin. Specifically, the Type-C interface is a USB interface appearance standard, which has a smaller volume than both Type-A and Type-B. It is an interface type that can be applied to both PCs (master devices) and external devices (slave devices, such as mobile phones, headphones 100 or charging boxes 900). The CC pin is mainly used to identify the type of device and communication inserted into the power receiving interface 311, and is also used to confirm the data transmission direction and the forward and reverse insertion direction. In some embodiments, setting the CC pin to be connected to the preset thermistor 312 can enable the external charging device to directly receive the relevant data information of the coupling state through the CC pin, improve the efficiency of the external charging device in judging the coupling state of the interface circuit 310 and the external charging device, and save the internal components and space of the interface circuit 310, thereby improving the space utilization of the interface circuit 310.

[0204] Of course, in other implementations, the power receiving interface 311 may be other interfaces such as Type-A or Type-B, and the identification pin A5 (B5) may be other pins such as a VBUS pin.

[0205] In some embodiments, the resistance of the preset thermistor 312 can change with the temperature change of the power receiving interface 311, so that the external charging device can detect the coupling state according to the resistance of the preset thermistor 312 via the identification pin A5 (B5). The preset thermistor 312 can be a sensor resistor, and its typical feature is that its resistance value can change with the change of temperature, that is, its resistance value is different at different temperatures, so the resistance of the preset thermistor 312 can directly reflect the temperature change of the power receiving interface 311. Setting the external charging device to directly detect the coupling state of the external charging device and the interface circuit 310 according to the resistance of the preset thermistor 312 can make the coupling state obtained by the external charging device more accurate.

[0206] In some embodiments, the identification pin A5 (B5) can be grounded via a preset thermistor 312. Specifically, the preset thermistor 312 is set between the identification pin A5 (B5) and the ground line. When the external charging device is connected to the power receiving interface 311, if the temperature of the preset thermistor 312 is too high, resulting in the preset thermistor 312 having a too high resistance, the preset thermistor 312 can block the connection between the identification pin A5 (B5) and the ground, and even the resistance of the preset thermistor will approach infinity to disconnect the connection between the external charging device and the ground, so that the external charging device can also determine the coupling status with the interface circuit 310 by connecting to the ground. Moreover, the preset thermistor 312 is directly connected to the identification pin A5 (B5), so that the preset thermistor 312 can directly detect and reflect the temperature change of the power receiving interface 311, and is not easily affected by other circuit components, and can also more accurately transmit the coupling status information of the interface circuit 310 and the external charging device to the external charging device.

[0207] In some embodiments, the preset thermistor 312 can be set so that when its resistance is within a predetermined resistance range, the coupling state detected by the external charging device is normal, and when its resistance is not within the preset resistance range, the coupling state detected by the external charging device is abnormal.

[0208] The predetermined resistance range may be set with reference to a temperature tolerance threshold of the power receiving interface 311 during normal operation, so that the predetermined resistance range can indicate that the operating temperature of the power receiving interface 311 is normal when coupled to an external charging device.

[0209] When the resistance value of the preset thermistor 312 is within the predetermined resistance range, it indicates that the temperature of the power receiving interface 311 is at a normal temperature. Under the normal temperature, the power receiving interface 311 can maintain normal power supply, communication and other functions with the external charging device, which further indicates that the external charging device detects that the coupling state between the power receiving interface 311 and the external charging device is normal.

[0210] When the resistance value of the preset thermistor 312 is not within the preset resistance range, it means that the temperature of the power receiving interface 311 detected by the preset thermistor 312 is too high. The power receiving interface 311 at the too high temperature may affect the normal communication or power supply functions with the external charging device. Therefore, the coupling state detected by the external charging device is abnormal.

[0211] For example, the preset resistance range may be 4.9KΩ-5.3KΩ. When the resistance of the preset thermistor 312 is within 4.9KΩ-5.2KΩ, the coupling state detected by the external charging device is normal. When the resistance of the preset thermistor 312 is less than 4.9KΩ or greater than 5.2KΩ, the coupling state detected by the external charging device is abnormal. Of course, in other embodiments, the preset resistance range may also be other values. For example, if different types of thermistors are used, the preset resistance range may also be other resistance ranges corresponding to the thermistors. For example, the preset resistance range may also be 4.7KΩ~5.4KΩ, 5KΩ~5.5KΩ, and other resistance ranges. This application will not list them one by one in detail.

[0212] By setting a predetermined resistance range of the preset thermistor 312 and detecting whether the real-time resistance value of the preset thermistor 312 is within the preset resistance range to reflect the coupling state between the power receiving interface 311 and the external charging device, the external charging device can obtain a more accurate detection result, thereby improving the safety of the interface circuit 310.

[0213] In some embodiments, the nominal resistance of the preset thermistor 312 may be 4.8KΩ to 5.4KΩ. This setting allows the preset thermistor 312 to detect a wider range of operating temperatures, making the preset thermistor 312 more sensitive, thereby making the external charging device detect the power receiving interface 311 more accurately. In other embodiments, depending on the model of the thermistor, the nominal resistance of the preset thermistor 312 may also be other resistances corresponding to the thermistor, for example, the nominal resistance of the preset thermistor 312 may also be 4.5KΩ to 5.5KΩ, 4.9KΩ to 5.3KΩ, and other values, which are not specifically limited in this application.

[0214] In some embodiments, the preset thermistor 312 can be set to have a resistance value within a predetermined resistance range when the temperature of the power receiving interface 311 is within a predetermined temperature range, and to have a resistance value not within the predetermined resistance range when the temperature of the power receiving interface 311 is not within the predetermined temperature range.

[0215] Specifically, the predetermined temperature range can refer to the normal temperature of the power receiving interface 311 when it is coupled to the external charging device and can realize normal power supply, communication and other operations, and the predetermined resistance range is configured to correspond to the predetermined temperature range. Therefore, if the temperature of the power receiving interface 311 is within the predetermined temperature range, the resistance value of the preset thermistor 312 is within the predetermined resistance range, and the coupling state detected by the external charging device is normal. If the temperature of the power receiving interface 311 is not within the predetermined temperature range, the resistance value of the preset thermistor 312 is not within the predetermined resistance range, and the coupling state detected by the external charging device is abnormal.

[0216] In some embodiments, if the operating temperature of the power receiving interface 311 is within the range of 0°C-45°C, the power receiving interface 311 can realize normal power supply, communication and other operations with the external charging device, then the predetermined temperature range can be set to 0°C-45°C, and the predetermined resistance range corresponding to the predetermined temperature range can be set to 4.9KΩ-5.3KΩ. When the coupling state detected by the external charging device is normal, it means that the temperature of the power receiving interface 311 is within the predetermined temperature range of 0°C-45°C, the resistance value of the preset thermistor 312 is within 4.9KΩ-5.3KΩ, and the power receiving interface 311 is in a normal working state. When the temperature of the power receiving interface 311 is greater than 45°C, the power receiving interface 311 is not suitable for receiving power or communication from the external charging device, then the resistance value of the preset thermistor 312 is correspondingly beyond the predetermined resistance range, for example, less than 4.9KΩ or greater than 5.3KΩ, and the coupling state detected by the external charging device is abnormal. In some embodiments, if the maximum temperature that the power receiving interface 311 can withstand is 80°C, the predetermined temperature range can be set to 0°C to 75°C. At this time, if the temperature of the power receiving interface 311 exceeds the predetermined temperature range, the resistance of the preset thermistor 312 will approach zero or infinity, and the coupling state detected by the external charging device is abnormal.

[0217] Of course, in other implementations, the predetermined temperature range may also be other values, and the predetermined resistance range corresponding to the predetermined temperature range may also be other values, which are not listed in detail one by one in this application.

[0218] In the above-mentioned embodiment, the predetermined resistance range is set according to the normal working temperature range of the power receiving interface 311, and the coupling state of the power receiving interface 311 and the external charging device is obtained based on this, so that the external charging device can timely monitor the temperature of the power receiving interface 311, timely grasp the abnormal situation of the power receiving interface 311 and respond in time, thereby improving the working safety of the interface circuit 310.

[0219] In some embodiments, Fig.29 As shown, the power receiving interface 311 may include a power supply pin A4 (B4), which may be used to receive a charging voltage output by an external charging device when the interface circuit 310 is coupled to the external charging device. When the external charging device detects that the coupling state is abnormal, it stops outputting the charging voltage to the power supply pin A4 (B4).

[0220] In some embodiments, the power supply pin A4 (B4) can be a VBUS pin, which can be connected to the pin of the output voltage in the external charging when the external charging device is coupled to the receiving power interface 311, so that the power supply pin A4 (B4) can receive the charging voltage output by the external charging device, thereby enabling the external charging device to charge the electronic device 300 through the power supply pin A4 (B4).

[0221] Specifically, when the external charging device detects that the coupling state is abnormal, it can be said that the temperature of the power receiving interface 311 exceeds the predetermined temperature range, and the temperature of the power receiving interface 311 is overheated or too cold. At this time, the external charging device stops outputting the charging voltage to the power supply pin A4 (B4), thereby protecting the power receiving interface 311 and avoiding safety accidents as much as possible.

[0222] In some embodiments, Fig.29 As shown, the number of the identification pins A5 (B5) can be two, and the number of the preset thermistors 312 can also be two, and the two identification pins A5 (B5) and the two preset thermistors 312 correspond one to one.

[0223] Setting two identification pins A5 (B5) can enhance the power supply communication function between the power receiving interface 311 and the external charging device, and setting two preset thermistors 312 can perform dual detection of the temperature of the power receiving interface 311, so that the external charging device can detect the temperature of the power receiving interface 311 more accurately.

[0224] In some embodiments, Fig.29 As shown, the number of the power supply pins A4 ( B4 ) may also be two, namely a first power supply pin A4 ( B4 ) and a second power supply pin A4 ( B4 ).

[0225] In some embodiments, Fig.29 As shown, the power receiving interface 311 may further include a ground pin, a receiving pin, a sending pin, any plug pin and an auxiliary pin.

[0226] The ground pin is used to connect the ground wire. For example, the ground pin may be a GND pin. Optionally, the number of the ground pins may be 4, and the four ground pins are respectively a first ground pin A1, a second ground pin A12, a third ground pin B1 and a fourth ground pin B12.

[0227] The sending pin may include a positive sending pin and a negative sending pin. The number of the positive sending pin and the negative sending pin may also be set to two. The positive sending pin includes a first positive sending pin A2 and a second positive sending pin B2, and the negative sending pin includes a first negative sending pin A3 and a second negative sending pin B3. The sending pin is used to transmit data at high speed. After the external device is plugged into the coupling receiving electrical interface 311, the sending pin is used to send the transmitted data to the external device at high speed.

[0228] The receiving pin may include a positive receiving pin and a negative receiving pin. The number of the positive receiving pin and the negative receiving pin may also be set to two, the positive receiving pin includes a first positive receiving pin A10 and a second positive receiving pin B10, and the negative receiving pin includes a first negative receiving pin A11 and a second negative receiving pin B11. After the external device is plugged into the coupling receiving electrical interface 311, the receiving pin is used to receive data transmitted by the external device at high speed.

[0229] Any plug pin may also include a positive any plug pin and a negative any plug pin. For example, the positive any plug pin is a D+ pin, and the negative any plug pin is a D- pin. The positive any plug pin and the negative any plug pin may also be set to two, the positive any plug pin includes a first positive any plug pin A6 and a second positive any plug pin B6, and the negative any plug pin includes a first negative any plug pin A7 and a second negative any plug pin B7. Any plug pins are used to transmit two groups of signals of USB2.0. The positive any plug pin and the negative any plug pin are cross-connected, so that the data is connected when the external device is connected in any direction.

[0230] The auxiliary pin is used to assist the power receiving interface 311 and the external charging device in transmitting auxiliary signals in some special modes. The auxiliary pin can be an SBU pin. The number of auxiliary pins can be 2, namely a first auxiliary pin A8 and a second auxiliary pin B8.

[0231] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
