[0001] This application is a divisional application of the Chinese Patent Application No. 202311507126.3, filed on November 10, 2023, with the title of “Earphone”. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic devices, in particular to earphones. BACKGROUND

[0003] With the continuous popularity of electronic devices, electronic devices have become an indispensable social and entertainment tool in people's daily life, and people's requirements for electronic devices are also getting higher and higher. Earphones, smart glasses and other electronic devices have been widely used in people's daily life, which can be used in cooperation with terminal devices such as mobile phones and computers to provide users with an auditory feast.

[0004] However, the ear hook of the existing earphone is difficult to balance the wearing stability and comfort, and cannot meet the needs. SUMMARY

[0005] The present application provides an earphone, which comprises a host module and an ear hook. The ear hook has a first end connected to the host module and a second end away from the first end, and is used to hang on the user's ear. The ear hook comprises an elastic skeleton and a covering piece. The elastic skeleton is arranged along the extension direction of the ear hook, and the covering piece is wrapped on the elastic skeleton. The covering piece is provided with a buffer cavity, which is arranged in a closed manner in the interior of the covering piece and is closer to the second end.

[0006] In the above manner, by setting the ear hook comprising the elastic skeleton and the covering piece, both of which have a certain elastic limit and can elastically deform within their respective elastic limits, the user can elastically deform the ear hook to fit the ear when wearing the earphone, effectively improving the comfort and stability of wearing. By setting the buffer cavity in the covering piece, the covering piece is more likely to elastically deform when the user wears the earphone, which can adapt to different ear widths and better fit the user's ear, achieving the function of self-adaptation. The buffer cavity is arranged in a closed manner in the interior of the covering piece, which can effectively prevent impurities such as dust and grease from entering the buffer cavity and causing damage to the buffer cavity, effectively prolonging the service life of the covering piece. At the same time, the deformation and resilience of the closed buffer cavity are more uniform, which is conducive to improving the wearing comfort and stability.

[0007] In some embodiments, the covering piece has a rear covering section located at the rear side of the ear in the wearing state, and the second end is located in the rear covering section. The buffer cavity is opened in the rear covering section.

[0008] In some embodiments, the host module includes a connecting end connected to the first end and a free end away from the connecting end, the free end is configured to extend into the concha of the ear in the wearing state, the free end and the rear covering section are configured to jointly hold the ear region from the front and rear sides of the ear region corresponding to the concha in the wearing state, and the buffer cavity is located at the part of the rear covering section for holding the ear region.

[0009] In some embodiments, the host module has a length direction, a width direction and a thickness direction perpendicular to each other, and a size of the buffer cavity in the width direction is greater than a size of the host module in the width direction.

[0010] In some embodiments, the elastic framework has a preset radial direction perpendicular to the extension direction of the elastic framework and passing through the buffer cavity, and the buffer cavity is spaced apart from the elastic framework in the preset radial direction.

[0011] In some embodiments, the buffer cavity is closer to the host module than the elastic framework in the preset radial direction, so that the buffer cavity is closer to the ear in the wearing state.

[0012] In some embodiments, the covering member includes a first covering part and a second covering part located on both sides of the buffer cavity along the preset radial direction, the first covering part and the second covering part are spaced apart to form the buffer cavity, the first covering part is closer to the host module than the second covering part for contacting the ear, and the elastic framework is arranged in the second covering part.

[0013] In some embodiments, the elastic framework extends from the first end to the second end.

[0014] In some embodiments, the ear hook includes a fixing block fixedly arranged at one end of the elastic framework close to the second end.

[0015] In some embodiments, the rigidity of the elastic framework is greater than the rigidity of the covering member.

[0016] In some embodiments, the material of the elastic framework is a non-metallic material. BRIEF DESCRIPTION OF DRAWINGS

[0049] The application will be described in further detail below with reference to the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustration of the application and do not limit the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, and all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application.

[0050] Reference to "embodiments" in this application means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the application can be combined with other embodiments.

[0051] In combination with Figure 1 , the ear 500 of the user can include physiological parts such as the external auditory canal 501, the concha cavity 502, the concha crus 503, the triangular fossa 504, the antihelix 505, the scapha 506, the helix 507, and the tragus 508. Among them, although the external auditory canal 501 has a certain depth and extends to the tympanic membrane of the ear, in order to facilitate description, in combination with Figure 1 , the external auditory canal 501 specifically refers to the entrance (i.e. the ear hole) away from the tympanic membrane without special description. Further, the concha cavity 502, the concha crus 503, the triangular fossa 504 and other physiological parts have a certain volume and depth; and the concha cavity 502 is directly connected with the external auditory canal 501, that is, the aforementioned ear hole can be simply regarded as located at the bottom of the concha cavity 502.

[0052] Further, different users can have individual differences, resulting in different sizes of the ear, such as different shapes and sizes. In order to facilitate description and reduce (even eliminate) individual differences of different users, a simulator containing the head and its (left and right) ear can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR. 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" can refer to the earphone 100 described in this application being worn on the ear of the aforementioned simulator. Of course, because different users have individual differences, the earphone 100 worn by different users may have certain differences from the earphone 100 worn on the ear of the aforementioned simulator, but such differences should be tolerated.

[0053] Referring to Figures 2 to 5The earphone 100 can include a main module 1 and an ear hook 2. The main module 1 can include a housing assembly 10 and a speaker 13. The main module 1 can also include a battery 14. The ear hook 2 can be hook-shaped, and the earphone 100 can be worn on the ear of a user through the ear hook 2. The ear hook 2 can be connected to the housing assembly 10. In the wearing state, the housing assembly 10 is located on the front side of the ear, and the ear hook 2 is at least partially located on the rear side of the ear of the user, so that the earphone 100 is hung on the ear. In addition, the housing assembly 10 can be used to form a receiving space 101. The speaker 13 can be arranged in the receiving space 101 to provide air conduction sound to the external auditory canal of the ear of the user. The battery 14 can also be arranged in the receiving space 101.

[0054] 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 can be orthogonal to the second direction Y (see FIG. 1A). Figure 5 ) Wherein the first direction X can refer to the length direction of the housing assembly 10, and the second direction Y can be the thickness direction of the housing assembly 10.

[0055] The housing assembly 10 is stacked on the front side of the ear of the user along the second direction Y. The housing assembly 10 further has a first end 102 and a second end 103 which are arranged opposite to each other along the first direction X. Wherein the first end 102 can refer to the part that faces the concha cavity 502 of the user during wearing, and the second end 103 can refer to the part that is farther away from the concha cavity 502 of the user than the first end 102. The second end 103 can be connected to the ear hook 2, which can be referred to as the connecting end 102 hereinafter, and the first end 102 can also be referred to as the free end 103 hereinafter.

[0056] The first end 102 of the housing assembly 10 at least partially extends into the concha cavity 502 of the ear of the user, and makes the external auditory canal of the ear of the user in an open state. Wherein the external auditory canal of the user in an open state means that the housing assembly 10 does not completely close the external auditory canal. In addition, due to individual differences of different users, when the earphone 100 is worn by different users, the housing assembly 10 can partially block the external auditory canal, but the external auditory canal is still not completely blocked.

[0057] In summary, when the user wears the earphone 100, the ear hook 2 is hung on the ear of the user and partially located on the rear side of the ear of the user, the housing assembly 10 is located on the front side of the ear of the user, and the second end 103 of the housing assembly 10 can extend into the concha cavity 502 of the user. In addition, the ear hook 2 can be connected to the second end 103 of the housing assembly 10 or the part close to the second end 103. Due to the shape of the ear, the shape of the ear hook 2 and the mounting position of the first end 102 of the housing assembly 10, the second end 103 of the housing assembly 10 is usually located in front of, above or front and above the first end 102 during wearing.

[0058] 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 close to the first end 102, and the battery 14 is arranged close to 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.

[0059] Optionally, the speaker 13 and the battery 14 are arranged spaced apart in the first direction X in the accommodating space 101. In this case, the speaker 13 and the battery 14 can be assembled in the shell assembly 10 at the same time, thereby being able to improve the assembly efficiency and reduce the use of lead wires.

[0060] Optionally, the shell assembly 10 can have a partition wall 104 for spacing the speaker 13 and the battery 14 apart. In this case, the partition wall 104 can space the battery 14 and the speaker 13 apart, reducing the possibility of water vapor in the speaker 13 polluting the battery 14.

[0061] Optionally, referring to 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 ear in the wearing state. In a 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 to intersect. Among them, the first axis ZX1 can be parallel to the vibration direction of the diaphragm of the speaker 13, and pass through the geometric center or the centroid of the barycenter of the speaker 13, the end face (such as a circular end face, a track-shaped end face). The second axis ZX2 can pass through the symmetry axis of the battery 14, pass through the geometric center or the centroid of the two end faces.

[0062] In this case, the speaker 13 and the battery 14 are arranged to be relatively inclined, which is conducive 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, thereby enabling the shell assembly 10 to be stably supported and to extend into the concha cavity 502 when worn.

[0063] Optionally, the intersection angle θ of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in the projection of the reference plane is an acute angle. Optionally, the intersection angle θ of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in the projection of the reference plane is located on the side of the shell 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°.

[0064] In this case, the inclination degree of the loudspeaker 13 relative to the battery 14 is relatively large, and the projection length of the loudspeaker 13 in the first direction X gradually decreases, thereby facilitating the reduction of the length of the shell assembly 10 in the first direction X.

[0065] Optionally, in the reference plane, the radial dimension of the loudspeaker 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 in parallel with the second direction Y. The radial dimension of the loudspeaker 13 can refer to the length of the loudspeaker 13 in the cross section of the loudspeaker 13 in the reference plane perpendicular to the first axis ZX1 of the loudspeaker 13. The radial dimension of the battery 14 can refer to the length of the battery 14 in the cross section of the battery 14 in the reference plane perpendicular to the second axis ZX2 of the battery 14.

[0066] In this case, since the radial dimension of the loudspeaker 13 is greater than the radial dimension of the battery 14, when the loudspeaker 13 is arranged to be inclined relative to the second direction Y, the change degree of the projection length of the loudspeaker 13 in the first direction X is greater than that of the battery 14 arranged to be inclined relative to the second direction Y, thereby facilitating the reduction of the length of the shell assembly 10 in the first direction X. In addition, the loudspeaker 13 is inclined relative to the battery 14, and while the second end 103 of the loudspeaker 13 (where the battery 14 is arranged) is in contact with the skin in front of the tragus 508 of the user, the diaphragm of the loudspeaker 13 can be substantially directed toward the external auditory canal of the user, thereby facilitating the sound propagation of the loudspeaker 13 to the external auditory canal of the user.

[0067] Optionally, the earphone 100 further comprises a circuit board 15 arranged in the accommodating space 101. The circuit board 15 controls the loudspeaker 13 to vibrate and sound when the battery 14 supplies power. In addition, the circuit board 15 can also have a radio frequency module for communication connection with a mobile terminal.

[0068] Optionally, the circuit board 15 is arranged in the shell assembly 10 and located on the side of the loudspeaker 13 and the battery 14 away from the user's ear, and the projection of the circuit board 15 along the second direction Y overlaps the loudspeaker 13 and the battery 14. The projection of the circuit board 15 overlapping the loudspeaker 13 and the battery 14 can be partial overlap or complete overlap. In this case, the loudspeaker 13 can be arranged on the side close to the user's ear, thereby facilitating the sound transmission to the user's ear.

[0069] Specifically, the shell assembly 10 comprises a first shell 111 and a second shell 112 which are matched with each other along the second direction Y. The first shell 111 is located on the side of the second shell 112 which is away from the user's ear. The loudspeaker 13 and the battery 14 can be fixed on the first shell 111 which is closer to the user's ear than the second shell 112 in the wearing state, and the circuit board 15 is fixed on the second shell 112. In this case, it can play a role of facilitating the assembly and disassembly of the earphone 100. Alternatively, the circuit board 15 is fixed on the second shell 112 of the shell assembly 10 by means of hot melting.

[0070] Referring to Figure 6 Alternatively, the earphone 100 further comprises a charging interface 16 arranged on the first shell 111 and a magnetic attraction element 17 arranged between the battery 14 and the first shell 111 along the second axis ZX2. In this case, the earphone 100 can be used with a charging box with magnetic attraction 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.

[0071] Referring to Figure 7 The charging box 900 can comprise a lower shell assembly 910 and an upper shell assembly 920. The lower shell assembly 910 can be provided with two profiled grooves 911 for accommodating the two earphones 100 respectively. The upper shell assembly 920 can be covered on the lower shell assembly 910 to close the profiled grooves 911.

[0072] Further, the charging box 900 can comprise a master control circuit board arranged in the lower shell assembly 910 and electrode terminals 912 arranged on the master control circuit board. The electrode terminals 912 can be arranged in multiple groups, for example, two groups, according to requirements. Accordingly, when any earphone 100 is put into 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 terminals 912 can comprise a positive power supply terminal and a negative power supply terminal, and can further comprise a detection terminal; the wires between them can form a triangle, for example, an equilateral triangle, or can be arranged along a straight line, for example, spaced apart and collinear.

[0073] Alternatively, the electrode terminals 912 can be exposed to the profiled grooves 911. When the earphone 100 is accommodated in the profiled grooves 911, the charging interface 16 is electrically connected with the electrode terminals 912.

[0074] In addition, the charging box 900 can include a magnetic attraction structure (not shown in the figure) arranged in the lower shell assembly 910. Among them, the magnetic attraction structure can be arranged in multiple groups according to needs, for example, two groups. After any earphone 100 is placed in the profiled groove 911, the magnetic attraction structure and the magnetic attraction element 17 in the earphone 100 can form a magnetic attraction pairing, so that the charging interface 16 and the electrode terminal 912 are in one-to-one corresponding contact.

[0075] The following shows several exemplary structures of the ear hook 2 of the earphone 200. Different exemplary structures can also be combined with each other to obtain other exemplary structures not described in detail that belong to the present embodiment.

[0076] In order to improve the wearing comfort of the ear hook 2, see the following first example structure of the example ear hook 2:

[0077] As shown in Figure 8 , the earphone 100 can include a main machine 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 main machine module 1. The ear hook 2 is used to hang on the ear of the user, and the ear hook 2 includes a elastic skeleton 21 and a cladding piece 22, the elastic skeleton 21 is arranged along the extension direction of the ear hook 2, and the cladding piece 22 is cladded on the elastic skeleton 21, and the cladding piece 22 is provided with a buffer cavity 220.

[0078] By arranging the ear hook 2 including the elastic skeleton 21 and the cladding piece 22, both of which have a certain elastic limit and can elastically deform within their respective elastic limits, the user can elastically deform the ear hook 2 to fit the ear when wearing the earphone 100, effectively improving the comfort and stability of wearing. By arranging the buffer cavity 220 in the cladding piece 22, the cladding piece 22 can more easily elastically deform when the user wears the earphone 100, and can adapt to different ear widths, thereby better fitting the user's ear and achieving the function of self-adaptation. Moreover, due to the existence of the buffer cavity 220, when the cladding piece 22 contacts the ear, the contact area between the cladding piece 22 and the user's ear can be increased, the pressure exerted by the cladding piece 22 on the ear can be reduced, and the wearing comfort of the user can be improved.

[0079] Further, as shown in Figure 8 , among the first end 201 and the second end 202, the buffer cavity 220 is closer to the second end 202.

[0080] The second end 202 is farther away from the host module 1 than the first end 201. The buffer cavity 220 is arranged closer to the second end 202. The part close to the second end 202 is more likely to elastically deform than the part close to the first end 201 when the user wears the earphone 100. The stability of the connection between the host module 1 and the ear hook 2 is ensured, the adaptability of the ear hook 2 is improved, and the wearing comfort of the user is effectively improved.

[0081] Further, as shown in Figure 9 , the cover member 22 has a rear cover section 222 located at the rear side of the ear in the wearing state. The second end 202 is located at the rear cover section 222, and the buffer cavity 220 is arranged in the rear cover section 222.

[0082] In the wearing state, the ear hook 2 is hung around the outer periphery of the ear of the user. The rear cover section 222 is located at the rear side of the ear. Arranging the buffer cavity 220 in the rear cover section 222 can improve the deformable range of the rear cover section 222, thereby better adapting to users with different ear widths, effectively reducing the pressure applied by the ear hook 2 to the rear side of the user's ear, and providing a better wearing experience for the user.

[0083] Optionally, as shown in Figure 9 , 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. At least part of the rear cover section 222 is arranged opposite to the free end 102. At least part of the buffer cavity 220 is arranged in the part of the rear cover section 222 opposite to the free end 102.

[0084] At least part of the rear cover section 222 is arranged opposite to the free end 102. At least part of the buffer cavity 220 is arranged in the part of the rear cover section 222 opposite to the free end 102. When the user wears the earphone 100, the rear cover section 222 and the free end 102 are located on both sides of the ear, respectively. The rear cover section 222 located at the rear side of the ear can elastically deform adaptively, effectively reducing the pressure applied to the user's ear when wearing, and improving the wearing comfort of the user.

[0085] Further, as shown in Figure 8 and Figure 9 , the free end 102 is arranged to extend into the concha cavity 502 of the ear in the wearing state. The free end 102 and the rear cover section 222 are arranged to jointly clamp the ear region from the front and rear sides of the ear region corresponding to the concha cavity 502 in the wearing state. The buffer cavity 220 is located in the part of the rear cover section 222 for clamping the ear region.

[0086] The free end 102 of the earphone 100 extends into the concha cavity 502 in the wearing state, so that the rear covering section 222 and the free end 102 can be clamped on the front and back sides of the user's ear when the user wears the earphone 100, increasing the stability of wearing and reducing the possibility of the earphone 100 falling. The part of the rear covering section 222 used for clamping the ear region is a part that applies relatively large pressure to the user's ear, and the setting of the buffer cavity 220 in this part can reduce the pressure applied by the rear covering section 222 to the ear, improving the user's wearing experience.

[0087] Optionally, as shown in Figure 8 and Figure 9 , the host module 1 has a length direction X, a width direction Z and a thickness direction Y perpendicular to each other, and the host module 1 is used to be stacked along the thickness direction Y on the ear in the wearing state. The front projection of the buffer cavity 220 on a reference plane perpendicular to the length direction X partially overlaps the front projection of the free end 102 on the reference plane.

[0088] The buffer cavity 220 is set to partially overlap the front projection of the free end 102 on a reference plane perpendicular to the length direction X, that is, the free end 102 and at least part of the rear covering section 222 where the buffer cavity 220 is located are clamped on both sides relative to the ear, so that when clamping the user's ear, it will not apply excessive pressure, ensuring the fit while improving comfort.

[0089] Optionally, as shown in Figure 9 and Figure 10 , the host module 1 has an inner side IS facing the ear and an outer side OS away from the ear along the thickness direction Y in the wearing state, and an upper side US and a lower side LS2 connecting the inner side IS and the outer side OS, the upper side US faces the ear hook 2, and the upper side US and the lower side LS2 are spaced apart in the width direction Z. The covering piece 22 is divided into a front covering section 221 and a rear covering section 222 by the extension plane of the upper side 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.

[0090] The ear hook 2 surrounds the host module 1 in an arc shape to position and fix the position of the host module 1 relative to the user's ear when the user wears it, and the size and width of everyone's ear are different. The rear covering section 222 opposite to the free end 102 has a larger deformable range due to the opening of the buffer cavity 220, so that it can better fit the user's ear when clamping the user's ear, increase the contact area of the rear covering section 222 with the ear, and will not apply excessive pressure to cause the user to be uncomfortable, effectively improving the user's use feeling.

[0091] Further, as shown in Figure 9As shown, the size T5 of the buffer cavity 220 in the width direction Z is greater than the size T2 of the main module 1 in the width direction Z.

[0092] The size T5 of the buffer cavity 220 in the width direction Z is greater than the size T2 of the main module 1 in the width direction Z, so that the buffer cavity 220 has sufficient deformation space to make the rear covering section 222 easy to deform, so that the rear covering section 222 can better fit the structure of the ear when clamping the user's ear, and the user is more convenient when adjusting the wearing.

[0093] Optionally, as shown, Figure 9 The covering member 22 includes a front covering section 221 and a rear covering section 222, the front covering section 221 is covered on the elastic framework 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 framework 21, and the buffer cavity 220 is formed in the rear covering section 222.

[0094] The rigidity of the elastic framework 21 can be greater than the rigidity of the covering member 22, so that the elastic framework 21 can support and maintain the relative shape of the ear hook 2, and the front covering section 221 is covered on the elastic framework 21, so that the user's ear does not directly contact the elastic framework 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 framework 21, that is, the rear covering section 222 can be located downstream of the elastic support 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 elastically deform relative to the front covering section 221, thereby increasing the comfort when fitting 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 greater elastic deformation to adapt to different ear widths, improve the application range and use of the earphone 100. Optionally, the material of the covering member 22 can include a non-metallic material such as silicone or rubber that has elasticity, and the material of the elastic framework 21 can include a metallic material or a non-metallic material, such as titanium wire, steel wire, or elastic plastic parts, etc., which are not limited herein.

[0095] Optionally, as shown, Figure 9 The ear hook 2 includes a fixed block 23, the fixed block 23 is fixedly arranged at one end of the elastic framework 21 close to the second end 202, the front covering section 221 is covered on the fixed block 23, and the extension length D2 of the rear covering section 222 in the extension direction is greater than the extension length D4 of the fixed block 23 in the extension direction.

[0096] The fixed block 23 is fixedly arranged at one end of the elastic framework 21 close to the second end 202, and the front covering section 221 covers the fixed block 23, thereby improving the stability of the fixation between the front covering section 221 and the elastic framework 21. The extension length D2 of the rear covering section 222 along the extension direction is greater than the extension length D4 of the fixed block 23 along the extension direction, so that the rear covering section 222 has a greater extension length, which can provide sufficient contact area when the user wears, thereby ensuring the wearing comfort of the user. Since the rear covering section 222 and the front covering section 221 can be relatively bent when the ear hook 2 is elastically deformed, the arrangement of the fixed block 23 can effectively reduce the possibility of the elastic framework 21 puncturing the rear covering section 222, thereby increasing the service life of the earphone 100.

[0097] 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 sufficient contact area with the ear of the user in the wearing state of the earphone 100, and the elastic framework 21 covered by the front covering section 221 can provide sufficient support strength to maintain the relative shape of the ear hook 2, thereby improving the appearance and service life of the earphone 100.

[0098] 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, the user's ear will be squeezed too much when wearing, and the wearing comfort is not high. If the value is too large, the ear hook 2 cannot hold the ear well when the user wears the earphone 100, which leads to unstable wearing.

[0099] Optionally, the extension length D2 of the rear covering section 222 is 10-30 mm. Within this length range, the ear hook 2 can have both comfort and appearance, thereby improving the user's use experience. If the value is too large, it can exceed the ear area of the user when wearing, thereby adversely affecting the convenience and appearance of use. If the value is too small, the area and length of the ear held when wearing are too small, which cannot hold the ear well, leading to unstable wearing.

[0100] Optionally, as shown in Figure 11a and Figure 12 , the ear hook 2 further includes a connector 24, which is fixedly arranged at one end of the elastic framework 21 close to the first end 201, and the connector 24 is fixedly connected with the host module 1. The ear hook 2 is fixedly connected 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.

[0101] Optionally, as shown in Figure 13As shown, the buffer cavity 220 is in a closed arrangement and formed in the interior of the covering member 22. The closed buffer cavity 220 can effectively prevent impurities such as dust and grease from entering the buffer cavity 220 and causing damage to the buffer cavity 220, thereby effectively improving the service life of the covering member 22.

[0102] Optionally, as shown, Figure 8 the buffer cavity 220 is in a hole or groove arrangement, thereby better adapting to the elastic deformation of the covering member 22 and improving the wearing comfort of the user. In some embodiments, the buffer cavity 220 is in a hole arrangement and extends through the covering member 22 along the thickness direction Y. In other embodiments, the buffer cavity 220 is in a long and curved through-hole arrangement, and the bending direction of the buffer cavity 220 matches the bending direction of the part of the covering member 22 where the buffer cavity 220 is formed.

[0103] Optionally, as shown, Figure 14 the number of buffer cavities 220 is at least two, and the at least two buffer cavities 220 are arranged at intervals along the extension direction of the ear hook 2, thereby allowing the covering member 22 to have a sufficient elastic range, improving the wearing comfort of the user, effectively reducing the possibility of damage due to the excessive width of the user's ear, and improving the service life of the ear hook 2.

[0104] Optionally, as shown, Figure 11a the ear hook 2 further comprises a filler 25, the hardness of the filler 25 being less than the hardness of the covering member 22, and the filler 25 being arranged in the buffer cavity 220, thereby providing certain support for the covering member 22 without affecting the elastic deformation of the covering member 22, improving the service life of the covering member 22, and thereby improving the service life of the ear hook 2.

[0105] 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 closer to the buffer cavity 220 than the outer side. The inner side of the covering member 22 is the side that contacts the user's ear, and the closer proximity of the buffer cavity 220 to the inner side can achieve better fit and softness of the covering member 22 when worn by the user, thereby improving the user's wearing comfort.

[0106] In the above examples involving Figure 9 , Figure 13 , etc., the elastic framework 21 and the buffer cavity 220 are arranged at intervals or adjacent to each other in the extension direction of the ear hook 2. However, Figure 15a and Figure 15bIn the shown example, 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 extending 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 being able to provide higher wearing stability.

[0107] Specifically, the buffer cavity 220 is closer to the main machine module 1 than the elastic skeleton 21 in the preset radial direction, so that the buffer cavity 220 is closer to the ear in the wearing state. Through the above arrangement, the buffer cavity 220 can provide elastic buffering when fitting the user's ear, so as to have better fitting degree and softness, and improve the wearing comfort.

[0108] Specifically, the cover 22 includes a first cover portion 2201 and a second cover portion 2202 located on both sides of the buffer cavity 220 along the preset radial direction; the first cover portion 2201 and the second cover portion 2202 are spaced apart to form the buffer cavity 220, and the first cover portion 2201 is closer to the main machine module 1 than the second cover portion 2202 for contacting the ear. In this way, the first cover portion 2201 is farther away from the elastic skeleton 21, and the buffer cavity 220 provides a larger space for deformation of the first cover portion 2201, thereby enabling the first cover portion 2201 to more effectively fit the ear and provide a softer fitting feeling, effectively improving the wearing comfort.

[0109] As shown in an example, Figure 15a The elastic skeleton 21 can be provided through the second cover portion 2202. Alternatively, the elastic skeleton 21 extends from the first end of the ear hook 2 to the second end 202 of the ear hook 2. In this way, the ear hook 2 can be provided with more complete and stronger support, 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 the cover 22 is not easily pierced when being bent, thereby improving the service life. Alternatively, the buffer cavity 220 is closer to the second end 202 of the ear hook 2 than the first end 201 of the ear hook 2.

[0110] In some embodiments, the elastic framework 21 further extends above the buffer cavity 220 (i.e. above the portion of the buffer cavity 220 close to the second end 202 of the ear hook 2) in the extending direction of the ear hook 2 from the first end 201 to the second end 202. That is, the elastic framework 21 can extend between the end position of the buffer cavity 220 and the second end 202. Such arrangement can provide better support. In other embodiments, the fixing block 23 can be connected to the end of the elastic framework 21 extending towards the second end 202 of the ear hook 2, the fixing block 23 extends from the elastic framework 21 towards the side of the buffer cavity 220 and bends and extends above the buffer cavity 220 (i.e. above the portion of the buffer cavity 220 close to the second end 202 of the ear hook 2) in the extending direction of the ear hook 2 from the first end 201 to the second end 202. That is, the fixing block 23 can extend between the end position of the buffer cavity 220 and the second end 202. Such arrangement can provide better support and prevent the cover 22 from being easily punctured by the elastic framework 21.

[0111] In some embodiments, the end of the elastic framework 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 framework 21 is greater than the circumferential dimension of the end of the fixing block 23 connected to the elastic framework 21. By inserting the elastic framework 21 into the fixing block 23 to achieve the connection between the elastic framework 21 and the fixing block 23, the connection stability between the two can be improved without affecting the support provided by the elastic framework 21 to the ear hook 2. Moreover, the circumferential dimension of the end of the fixing block 23 away from the elastic framework 21 is greater than the circumferential dimension of the end of the fixing block 23 connected to the elastic framework 21, which helps to reduce the production process difficulty of the fixing block 23 while achieving the bending extension of the fixing block 23, and improves the strength and service life of the fixing block 23. Moreover, the fixing block 23 and the cover 22 can have a larger contact area, which helps to reduce the processing difficulty of the ear hook 2 and improve the service life of the ear hook 2.

[0112] Optionally, as shown in Figure 11b and Figure 15a , 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 framework 21, and the first positioning hole 223 and the second positioning hole 231 are oppositely arranged. The oppositely arranged first positioning hole 223 and second positioning hole 231 can allow external positioning devices to position the fixing block 23 through the first positioning hole 223, so that the shape and position size between the components of the ear hook 2 are more accurate, which helps to improve the yield of the ear hook 2. Moreover, on the basis that the circumferential dimension of the end of the fixing block 23 away from the elastic framework 21 is greater than the circumferential dimension of the end connected to the elastic framework 21, the aperture of the second positioning hole 231 can also be relatively increased, which is more convenient for the operation and alignment of external positioning devices.

[0113] In some embodiments, as shown in Figure 15a The elastic skeleton 21 is inserted into the connector 24 at an end close to the first end 201, and the extension direction of the end of the elastic skeleton 21 close to the first end 201 and the extension direction of the connector 24 intersect with each other. Such arrangement can realize stable connection between the connector 24 and the host module 1 and stable connection between the elastic skeleton 21 and the connector 24 at the same time, which is conducive to improving the connection stability between the elastic skeleton 21 and the connector 24 and the connection stability between the ear hook 2 and the host module 1.

[0114] Optionally, as shown in Figure 14 and Figure 15a The host module 1 has a length direction X, a width direction Z and a thickness direction Y perpendicular to each other, the host module 1 is used to be stacked along the thickness direction Y on the ear 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 included angle Q1 towards the ear hook 2, the extension direction of the connector 24 and the length direction X have a second included angle Q2 towards the ear hook 2, and the first included angle Q1 is smaller than the second included angle Q2. By setting the first included angle Q1 and the second included angle Q2 as two included angles with different angles, the elastic skeleton 21 and the connector 24 intersect with each other, and by reasonably setting the angle of the first included angle Q1 and the second included angle Q2, the end of the elastic skeleton 21 connected with 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 included angle Q1 is 70°-110°, for example, it can be 80°, 85°, 90°, 95°, 100°, etc., and the second included angle Q2 is 90°-130°, for example, it can be 100°, 105°, 110°, 115°, 120°, etc.

[0115] As shown in Figure 15bIn another example shown, the elastic frame 21 can extend to the second covering portion 2202. Optionally, the ear hook 2 includes a fixing block 23, which is disposed at the end of the elastic frame 21 near the second end 202, and the covering member 22 covers the fixing block 23. The fixing block 23 is located on the side of the buffer cavity 220 away from the main unit module 1, that is, the fixing block 23 can be located in the second covering portion 2202. With this arrangement, the side of the buffer cavity 220 near the main unit module 1 can increase the contact area with the user's ear through deformation during wearing, reducing pressure on the ear and fitting the user's ear more comfortably. On the one hand, this improves wearing comfort, and on the other hand, this deformation buffer can achieve elastic tightness to the ear, thereby enhancing wearing stability. Furthermore, the fixing block 23 and the elastic skeleton 21 are located on the side of the buffer cavity 220 away from the main unit module 1. This enhances the support strength of the ear hook 2 without affecting the deformation of the buffer cavity 220, allowing the buffer cavity 220 to deform more stably, thereby ensuring a comfortable fit and wearing stability with the user's ear. Additionally, the fixing block 23 reduces the possibility of the elastic skeleton 21 puncturing the second covering part 2202, improving the stability and reliability of the covering part 22.

[0116] 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 closer to the end of the buffer cavity 220 near the second end 102. In this way, the buffer cavity 220 can be surrounded more extensively in the extension direction of the ear hook 2, which can effectively provide stronger support for the buffer cavity 220 to deform more and fit the ear better, and can also provide stronger support for the entire ear hook 2, ensuring the support performance of the entire ear hook 2.

[0117] To improve the wearing comfort of ear hook 2, please refer to the second example structure of ear hook 2 below:

[0118] like Figure 16 As shown, the earphone 100 may include a main unit module 1 and an ear hook 2. The ear hook 2 is connected to the main unit module 1. The ear hook 2 includes a connecting body 20 and an elastic buffer portion 26. The connecting body 20 is connected to the main unit module 1, and the elastic buffer portion 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 portion 26 forms a second portion of the outer surface of the ear hook 2, with at least a portion of the second portion of the outer surface facing the main unit module 1. The hardness of the elastic buffer portion 26 is less than the hardness of the connecting body 20.

[0119] By setting the ear hook 2 including the connecting body 20 and the elastic buffer part 26, the elastic buffer part 26 has a certain elastic limit and can elastically deform within the elastic limit, so that the user can elastically deform the ear hook 2 to fit the ear when wearing the earphone 100, effectively improving the comfort and stability of wearing. The hardness of the elastic buffer part 26 is less than that of the connecting body 20, and at least part of the second part outer surface of the elastic buffer part 26 can be directly contacted with the ear when the user wears the earphone 100, while the relatively high hardness of the connecting body 20 plays a supporting role, effectively improving the wearing comfort of the user while ensuring the aesthetics of the ear hook 2.

[0120] Optionally, the elastic buffer part 26 and the connecting body 20 are detachably connected. By setting the elastic buffer part 26 and the connecting body 20 as two parts that can be detachably connected, it is convenient for production and assembly, and the user's convenience and the service life of the earphone 100 can be improved when a certain part is damaged.

[0121] Optionally, the elastic buffer part 26 and the connecting body 20 are slidably connected, which facilitates the installation and disassembly between the elastic buffer part 26 and the connecting body 20, thereby improving the assembly and disassembly efficiency of the ear hook 2, and facilitating the subsequent individual replacement of the elastic buffer part 26 or the connecting body 20.

[0122] In some embodiments, as shown in Figure 17 The elastic buffer part 26 is provided with a sliding edge 261, and the connecting body 20 is provided with a sliding groove 203, and the sliding edge 261 is slidably embedded in the sliding groove 203, effectively fixing the elastic buffer part 26 and the connecting body 20, and facilitating installation and disassembly.

[0123] In some embodiments, the elastic buffer part 26 and the connecting body 20 are adhesively or magnetically attached. The adhesion and magnetic attachment structure is simple, convenient to install and disassemble, and does not need to set an additional structure to realize the connection between the elastic buffer part 26 and the connecting body 20, effectively saving production costs and reducing subsequent maintenance costs.

[0124] Optionally, as shown in Figure 16 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, and the host module 1 is used to be stacked on the ear of the user in the wearing state, and at least part of the second part outer surface is arranged opposite to the free end 102.

[0125] The connecting end 103 of the host module 1 is connected with the ear hook 2, and the free end 102 is arranged opposite to at least part of the outer surface of the second part of the elastic buffer 26, so that when the user wears the earphone 100, the free end 102 and the at least part of the outer surface of the second part are clamped on both sides of the ear, and the elastic buffer 26 can be elastically deformed to facilitate the wearing of users with different ear sizes, while ensuring the stability of the wearing of the earphone 100, the adaptability of the earphone 100 is effectively improved.

[0126] Optionally, as shown in Figure 18 and Figure 19 , the extension length D3 of the elastic buffer 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, so that the elastic buffer 26 has sufficient contact length with the user's ear when the user wears it, thereby improving the contact area between the elastic buffer 26 and the ear, better fitting the ear, and improving the wearing comfort of the user.

[0127] Optionally, as shown in Figure 17 , in a part of the extension direction of the ear hook 2, the elastic buffer 26 and the connecting body 20 can be simultaneously arranged 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 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 26 with lower hardness can reduce the discomfort caused by the pressure applied by the ear hook 2 when the user wears it, and improve the wearing comfort of the user.

[0128] Optionally, as shown in Figure 16 and Figure 18 , the host module 1 has a length direction X, a width direction Z and a thickness direction Y 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 26 on a reference plane perpendicular to the length direction X partially overlaps the orthographic projection of the free end 102 on the reference plane, that is, the orthographic projection of the elastic buffer 26 on the reference plane parallel to the width direction Z and the thickness direction Y partially overlaps the orthographic projection of the free end 102 on the reference plane.

[0129] The elastic buffer 26 is arranged to have an orthographic projection on a reference plane perpendicular to the length direction X partially overlapping the orthographic projection of the free end 102 on the reference plane, that is, the free end 102 and at least part of the elastic buffer 26 are clamped on both sides of the ear, so that when the ear of the user is clamped, the stability is ensured without applying excessive pressure, the fitting degree is ensured while the comfort is improved.

[0130] Further, as shown inFigure 16 and Figure 18 As shown, the elastic buffer portion 26 is closer to the main unit module 1 than the connecting body 20, thereby increasing the contact area between the less rigid elastic buffer portion 26 and the user's ear. This allows for a better fit to the ear structure when holding the user's ear, resulting in greater comfort. In some embodiments, the elastic buffer portion 26 may be closer to the main unit module 1 in the radial direction of the ear hook 2 than the connecting body 20, wherein the radial direction of the ear hook 2 is perpendicular to the extending direction of the ear hook 2.

[0131] Furthermore, such as Figure 16 , Figure 18 and Figure 19 As shown, the elastic buffer 26 and the connecting body 20 are spliced ​​together, thereby increasing the contact area between the less rigid elastic buffer 26 and the user's ear when the ear hook 2 is hung on the user's ear, and reducing the contact area between the more rigid connecting body 20 and the user's ear, thus improving user comfort. In some embodiments, the elastic buffer 26 and the connecting body 20 can be spliced ​​together, for example, in the normal F of the outer contour of the ear hook 2 and in the extending direction of the ear hook 2, wherein the normal F of the outer contour of the ear hook 2 is perpendicular to the outer contour of the ear hook 2. The splicing of the elastic buffer 26 and the connecting body 20 in the normal F of the outer contour of the ear hook 2 facilitates positioning and installation, effectively reducing assembly difficulty.

[0132] Optionally, such as Figure 16 , Figure 18 and Figure 19 As shown, the ear hook 2 has a first end 201 and a second end 202 arranged opposite to each other. The first end 201 is connected to the main unit module 1, and the second end 202 is located in the elastic buffer portion 26, which is circumferentially closed at the second end 202. The portion of the elastic buffer portion 26 forming the second end 202 is located below the connecting body 20 in the direction from the first end 201 to the second end 202 of the ear hook 2, while the other portion is located on the side of the connecting body 20 facing the main unit module 1. The splicing of the elastic buffer portion 26 and the connecting body 20 reduces assembly difficulty and improves the stability and reliability of the connection. By positioning a portion of the elastic buffer 26 on the side of the connecting body 20 facing the main module 1, the elastic buffer 26 makes greater contact with the user's ear compared to the connecting body 20, thereby improving user comfort. Furthermore, the portion of the elastic buffer 26 forming the second end 202 is located below the connecting body 20 in the direction from the first end 201 to the second end 202 of the ear hook 2, which helps to increase the contact area between the elastic buffer 26 and the ear, improving both wearing comfort and stability. The elastic buffer 26 is circumferentially closed at the second end 202, reducing the entry of external impurities into the elastic buffer 26 and preventing damage to its internal structure, thus increasing its lifespan.

[0133] Further, as shown in Figures 16 to 19 the first end 201 is connected to the host module 1, the circumferential size R1 of the elastic buffer portion 26 gradually increases or stepwise increases from the first end 201 to the second end 202. The first end 201 needs higher hardness to ensure the stability and reliability of the connection of the ear hook 2 to the host module 1, and needs to provide sufficient support force to maintain the relative position between the ear hook 2 and the host module 1, so that the user can normally wear and use the earphone 100, and therefore the circumferential size R1 of the elastic buffer portion 26 with lower hardness is smaller near the first end 201, and the circumferential size R1 of the elastic buffer portion 26 gradually increases or stepwise increases from the first end 201 to the second end 202, which can effectively improve the user's comfort.

[0134] Optionally, as shown in Figures 16 to 19 the connecting body 20 and the elastic buffer portion 26 are connected in sequence along the extension direction of the ear hook 2, and the second end 202 is located at the elastic buffer portion 26. The elastic buffer portion 26 and the connecting body 20 can smoothly transition at the end connected to each other in the extension direction of the ear hook 2, thereby improving the appearance and stability of the connection of the ear hook 2 while ensuring the comfort of wearing. In some embodiments, the circumferential size R2 of the connecting body 20 gradually decreases from the end connected to the elastic buffer portion 26 to the first end 201. In some embodiments, the circumferential size R2 of the connecting body 20 gradually decreases from the end connected to the elastic buffer portion 26 to the first end 201, and then gradually increases. In other embodiments, the circumferential size R2 of the connecting body 20 at the end connected to the elastic buffer portion 26 is the maximum circumferential size of the connecting body 20.

[0135] Optionally, as shown in Figure 20 the connecting body 20 includes an elastic skeleton 21 and a cladding 22, the cladding 22 is cladded on at least part of the elastic skeleton 21, the elastic buffer portion 26 is connected to the cladding 22, the hardness of the elastic buffer portion 26 is less than the hardness of the cladding 22, and the hardness of the cladding 22 is less than the hardness of the elastic skeleton 21. The elastic skeleton 21 provides main support to maintain the relative shape of the ear hook 2, avoiding the user from being unable to normally use due to deformation of the ear hook 2, and the cladding 22 and the elastic buffer portion 26 with hardness decreasing in sequence can avoid the elastic skeleton 21 with higher hardness from directly contacting the user's ear, thereby improving the comfort of the user. Optionally, a buffer cavity 220 is provided in the ear hook 2, which can be provided in the cladding 22, or in the elastic buffer portion 26, or in the cladding 22 and the elastic buffer portion 26, to increase the softness and the deformable range, thereby improving the comfort of the user. For details, please refer to the description of the above embodiments.

[0136] In some embodiments, the cover 22 covers part of the elastic framework 21, and the elastic buffer 26 covers another part of the elastic framework 21, and the elastic framework 21 serves as a support and a connecting bridge of the ear hook 2, and improves the connection stability and reliability of the ear hook 2.

[0137] In some embodiments, the cover 22 and the elastic buffer 26 are sequentially connected in the extension direction, the elastic buffer 26 does not cover the elastic framework 21, but is located downstream of the elastic framework 21 in the extension direction of the ear hook 2, so that the softness and the deformable range of the elastic buffer 26 are not affected, and the user's use comfort and the application range of the earphone 100 are maximized.

[0138] In order to improve the wearing comfort of the ear hook 2, see the following example of the third example structure of the ear hook 2:

[0139] In combination Figures 21 to 24 As shown in the figure, the ear hook 2 has a first end 201 and a second end 202 arranged away from each other, and the first end 201 is connected to the host module 1. The ear hook 2 is used to hang on the user's ear 500. Among them, the ear hook 2 includes an elastic framework 21, a cover 22 and a fixed block 23, the elastic framework 21 is arranged along the extension direction from the first end 201 to the second end 202. The cover 22 includes a front cover section 221 and a rear cover section 222, the front cover section 221 and the rear cover section 222 are connected to each other in the extension direction, the fixed block 23 is arranged at one end of the elastic framework 21 away from the first end 201, and the front cover section 221 is covered on the elastic framework 21 and the fixed block 23. The rear cover section 222 does not cover the elastic framework 21 and the fixed block 23, but is located downstream of the fixed block 23 in the extension direction. The extension length D2 of the rear cover section 222 along the extension direction is greater than or equal to the extension length D4 of the fixed block 23 along the extension direction. In this way, the elastic framework 21 can be prevented from piercing the cover 22, it is easier to process and form, and the processing accuracy can be effectively improved.

[0140] The host module 1 is used to realize the playing of sound. The ear hook 2 is 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 framework 21 can support the cover 22 in the ear hook 2. The elastic framework 21 can be deformed to a certain extent. The cover 22 can cover the elastic framework 21 and can be deformed accordingly with the deformation of the elastic framework 21. In this way, the user can adjust the shape of the ear hook 2 by adjusting the shape of the elastic framework 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 wear more stable.

[0141] By setting the rear covering section 222 on the basis of the front covering section 221, the extension length D2 of the rear covering section 222 in the extension direction is set to be greater than or equal to the extension length D4 of the fixed block 23 in the extension direction, so that the rear covering section 222 has sufficient length in the extension direction, the length of the ear hook 2 in the extension direction can be increased, and the wearing comfort and stability of the earphone 100 can be improved. By setting the rear covering section 222 not to cover the elastic framework 21 and the fixed block 23, the rear covering section 222 is not supported by the elastic framework 21 and the fixed block 23, so that the force of the rear covering section 222 on the human ear can be reduced, and the wearing comfort of the user can be improved. At the same time, the elastic framework 21 is not arranged in the rear covering section 222, so that the material of the elastic framework 21 can be reduced, and the cost can be reduced.

[0142] If the fixed block 23 is not arranged, when the rear covering section 222 is relatively bent relative to the front covering section 221, the elastic framework 21 has a risk of piercing the covering member 22 (for example, the rear covering section 222). Here, by arranging the fixed block 23 at the end of the elastic framework 21 away from the first end 201, the direct contact of the end of the elastic framework 21 away from the first end 201 with the rear covering section 222 when the rear covering section 222 is bent relative to the front covering section 221 can be reduced, so that the risk of the end of the elastic framework 21 away from the first end 201 piercing the covering member 22 (for example, the rear covering section 222) can be reduced, and the discomfort caused by the end of the elastic framework 21 away from the first end 201 can be reduced.

[0143] Further, the radial dimension of the fixed block 23 perpendicular to the extension direction can be greater than the radial dimension of the end of the elastic framework 21 away from the first end 201 perpendicular to the extension direction. In other words, the circumferential dimension of the fixed block 23 can be greater than the circumferential dimension of the elastic framework 21.

[0144] Optionally, the material of the covering member 22 is silicone, plastic or rubber.

[0145] In combination Figure 22 In some embodiments, the extension length D2 of the rear covering section 222 in the extension direction is 10-25 mm.

[0146] According to the large model data of the human ear, as the front covering section 221 is closer to the hanging position of the ear tip rear side (for the ear hook 2 to hang), the farther the ear hook 2 extends to the second end 202, the greater the deviation of the ear hook 2 from the natural contour of the human ear, and the greater the deformation ability required for the ear hook 2. By setting the extension length D2 of the rear covering section 222 in the extension direction to be greater than or equal to 10 mm, the rear covering section 222 can have sufficient length and deformation ability in the extension direction, and the shape stability (fatigue resistance) and comfort (adaptability to a wider population) of the ear hook 2 can be well balanced. In addition, when the rear covering section 222 is thus set, the fixing block 23 can not pierce the covering member 22 of the rear covering section 222.

[0147] By setting the extension length D2 of the rear covering section 222 in the extension direction to be less than or equal to 25 mm, the appearance structure of the earphone 100 can be more concise. Further, the extension length D2 of the rear covering section 222 in the extension direction is 12-25 mm. For example, the extension length D2 of the rear covering section 222 in the extension direction is 12 mm, 15 mm, 18 mm, 20 mm, or 22 mm.

[0148] Optionally, the extension length D1 of the front covering section 221 in the extension direction is 35-80 mm.

[0149] By setting the extension length D1 of the front covering section 221 in the extension direction to be greater than or equal to 35 mm, the front covering section 221 can have sufficient length in the extension direction, improving the wearing stability of the earphone 100. By setting the extension length D1 of the front covering section 221 in the extension direction to be less than or equal to 70 mm, the force of the front covering section 221 on the human ear can be reduced, the wearing comfort of the user can be improved, and the material of the elastic skeleton 21 can be reduced, thereby reducing the cost. For example, the extension length D1 of the front covering section 221 in the extension direction is 40 mm, 45 mm, 48 mm, 50 mm, 55 mm, 60 mm, 65 mm, or 68 mm.

[0150] Optionally, the extension length D4 of the fixing block 23 in the extension direction is 6-15 mm. For example, the extension length D4 of the fixing block 23 in the extension direction of the ear hook 2 can be 8 mm, 10 mm, or 12 mm. In this way, on the one hand, the fixing block 23 can have sufficient and reasonable length to cover the end of the elastic skeleton 21, making it difficult for the elastic skeleton 21 to pierce the covering member 22, thereby effectively reducing the probability of the end of the elastic skeleton 21 piercing the covering member 22, and also improving the fixing effect of the elastic skeleton 21 and the fixing block 23. On the other hand, the above size setting can enable the covering member 22 and the fixing block 23 to have good fixing effect, so that the covering member 22 better wraps the fixing block 23, and the fixing effect between the fixing block 23 and the elastic skeleton 21 is also better.

[0151] In combination Figure 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.

[0152] According to the large model data of the human auricle, since the front covering section 221 is closer to the position of hanging behind the ear tip (for the ear hook 2 to hang), the farther the ear hook 2 extends to the second end 202, the greater the deviation of the ear hook 2 from the natural contour of the human ear, and thus the greater the deformation ability required for the ear hook 2 to the rear. 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 a deformation force arm for the rear covering section 222 to obtain higher deformation ability, and the shape stability (fatigue resistance) and comfort (adaptability to a wider population) of the ear hook 2 can be well balanced.

[0153] For example, 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 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 covering section 221 along the extension direction to the extension length D2 of the rear covering section 222 along the extension direction is in the range of 3.3-3.4.

[0154] 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 good wearing stability and comfort at the same time.

[0155] In combination Figure 23 In some embodiments, the end of the elastic framework 21 away from the first end 201 is inserted into the fixed block 23.

[0156] By setting the end of the elastic framework 21 away from the first end 201 to be inserted into the fixed block 23, the fixed block 23 can cover the end of the elastic framework 21 away from the first end 201, which is conducive to the stable fixation of the fixed block 23 to the end of the elastic framework 21 away from the first end 201, thereby reducing the damage of the end of the elastic framework 21 away from the first end 201 to the covering piece 22 and reducing the discomfort caused by the end of the elastic framework 21 away from the first end 201.

[0157] In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved. Figure 23 In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved.

[0158] The front covering section 221 provides stronger support to the user's ear 500, while the rear covering section 222 provides weaker support to the user's ear 500. By chamfering or curving the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23, the support provided by the rear covering section 222 and the front covering section 221 to the user's ear 500 can be more smoothly transitioned at the junction, thereby improving the user's wearing comfort.

[0159] In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved. Figure 23 In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved. Figure 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.

[0160] In the production process of the ear hook 2, the first positioning hole 223 can avoid external positioning devices, thereby allowing the external positioning devices to position the fixing block 23 through the first positioning hole 223, and thus the deformation of the elastic framework 21 during the production process of the ear hook 2 can be reduced, the shape and position size between the components of the ear hook 2 can be more accurate, and the quality rate of the ear hook 2 can be improved.

[0161] The first positioning hole 223 provided in the front covering section 221 can be used by external positioning devices 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 external positioning devices to act on the end surface of the fixing block 23 facing the rear covering section 222. For example, the front covering section 221 and the rear covering section 222 are both provided with the first positioning hole 223, so that the external positioning devices can act on different positions of the fixing block 23, which is conducive to improving the fixing effect of the positioning block.

[0162] Further, the first positioning hole 223 is provided in pairs on the front covering section 221 and / or the rear covering section 222. The two first positioning holes 223 are oppositely arranged, so that the opposite sides of the fixing block 23 can be exposed through the first positioning hole 223. In this way, the fixing block 23 can be positioned, and the fixing effect of the fixing block 23 can be improved.

[0163] In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved. Figure 23 In some embodiments, the connecting part between the end surface of the rear covering section 222 and the peripheral side surface of the fixing block 23 is chamfered or curved. Figure 25In some embodiments, the first positioning hole 223 is arranged on the circumferential side of the front covering section 221 and / or the rear covering section 222, and the circumferential side of the front covering section 221 and / or the rear covering section 222 is further provided with a groove 224, and the first positioning hole 223 is arranged on the groove bottom of the groove 224.

[0164] 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 a deformation space for the deformation of the front covering section 221 and / or the rear covering section 222, so that the front covering section 221 and / or the rear covering section 222 is more easily deformed when stressed, 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 correctly wear and use the earphone 100 without using vision.

[0165] In combination Figure 23 and Figure 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 in the direction close to the second end 202.

[0166] In this way, it is convenient for the user to simultaneously sense the second end 202 and the groove 224 through touch, so that the user is more easily to sense the posture and position of the earphone 100 in space through touch. At the same time, the groove 224 is more located at the rear covering section 222, which is conducive to the deformation of the rear covering section 222.

[0167] In combination Figure 21 , Figure 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 perpendicular to each other, and the host module 1 is used to be stacked on the ear 500 along the thickness direction Y in the wearing state. The first positioning hole 223 extends along the thickness direction Y.

[0168] The covering member 22 can be covered on the elastic framework 21 by injection molding, and the first positioning hole 223 is formed on the covering member 22 by injection molding. By arranging the first positioning hole 223 to extend along the thickness direction Y, the opening direction of the mold is consistent with the direction of the mold away from the first positioning hole 223 during the injection molding process, so as to facilitate the demolding of the covering member 22.

[0169] Further, the first positioning hole 223 is arranged on the side of the ear hook 2 facing the host module 1 in the wearing state. In this way, it is convenient for the ear 500 to shield the first positioning hole 223 in the wearing state, and improve the appearance of the earphone 100.

[0170] In combination Figure 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 oppositely arranged and communicated.

[0171] By arranging the second positioning hole 231, the fixing block 23 can be positioned by an external positioning device, which is beneficial to improve the fixing effect. For example, the external positioning device can be inserted into the second positioning hole 231 to position the fixing block 23.

[0172] Further, the second positioning hole 231 is a blind hole, which can facilitate demolding during injection molding, and can also prevent the second positioning hole 231 from penetrating through the fixing block 23, so that the fixing block 23 can maintain a high strength.

[0173] Further, the second positioning hole 231 is arranged in pairs. The two second positioning holes 231 are oppositely arranged, so that the opposite sides of the fixing block 23 can be fixed through the second positioning holes 231. In this way, the fixing block 23 can be positioned and the fixing effect of the fixing block 23 can be improved.

[0174] In combination with Figure 22 In some embodiments, the earphone 100 further comprises a functional piece 26a, which is detachably connected to the first positioning hole 223. In this way, the appearance and functionality of the earphone 100 can be improved. For example, the user wears one earphone 200 on each of the left ear and the right ear. The functional piece 26a can be arranged to detachably connect the two earphones 100 together (for example, clamping, bonding, threaded connection, magnetic attraction connection, or through additional fixing pieces, etc.), which reduces the risk of losing the earphone 100.

[0175] In combination with Figure 22 Further, the functional piece 26a is a hanging rope, which can be used to connect the two earphones 100 together. Of course, the functional piece 26a can also be an arc-shaped metal piece, and the two functional pieces 26a can be spliced to form a larger arc-shaped structure.

[0176] In some embodiments, the hardness of the fixing block 23 is greater than the hardness of the cladding piece 22. By arranging the fixing block 23 to have a greater hardness, the protection effect of the fixing block 23 on the cladding piece 22 can be improved. By arranging the cladding piece 22 to have a smaller hardness, the wearing comfort of the user can be improved.

[0177] Optionally, the material of the cladding piece 22 is a relatively soft plastic, silicone or rubber, and the material of the fixing block 23 is a relatively hard plastic or metal.

[0178] In combination with Figure 22 and Figure 23Optionally, the front covering section 221 and the rear covering section 222 are integrally formed, and the front covering section 221 integrally covers the outer periphery of the elastic framework 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.

[0179] In this way, the covering member 22 has a good and uniform covering effect, and the front covering section 221 and the rear covering section 222 can be stably connected.

[0180] In combination Figure 22 In some embodiments, 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, and at least part of the rear covering section 222 is arranged opposite to the free end 102. In this way, in the wearing state of the earphone 100, at least part 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 at least part of the rear covering section 222 and the free end 102 exert equal force arms on both sides of the same position of the ear 500, so as to improve the wearing comfort.

[0181] In combination Figure 22 In some embodiments, 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, and the fixing member is arranged opposite to the free end 102. In this way, in the wearing state of the earphone 100, the fixing member and the free end 102 are respectively located on both sides of the same position of the ear 500, and the host module 1 and the front covering section 221 exert equal force arms on both sides of the ear 500, so as to improve the wearing stability.

[0182] In combination Figure 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 perpendicular to each other, and the host module 1 is used to be stacked on the ear 500 along the thickness direction Y in the wearing state. The size T1 of the rear covering section 222 along the width direction Z is greater than the size T2 of the host module 1 along the width direction Z.

[0183] In this way, the rear covering section 222 has sufficient length along the width direction Z, and the wearing comfort and stability of the earphone 100 are improved.

[0184] In combination Figure 21 And Figure 22In some embodiments, the main module 1 has an inner side IS facing the ear 500 along the thickness direction Y and an outer side OS facing away from the ear 500 in the wearing state, and an upper side US and a lower side LS2 connecting the inner side IS and the outer side OS, the upper side US and the lower side LS2 are spaced apart in the width direction Z. The second end 202 is located at the rear covering section 222, and the rear covering section 222 extends beyond the lower side LS2 in the width direction Z.

[0185] In this way, the rear covering section 222 can have sufficient length in the width direction Z, improving the wearing comfort of the earphone 100, and at the same time facilitating the ear hook 2 to have sufficient length in the width direction Z, improving the wearing stability of the earphone 100.

[0186] In combination Figure 22 In some embodiments, at least part 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 6-15mm. For example, part 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 part 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 can be 8mm, 10mm or 12mm.

[0187] In this way, at least part of the fixing block 23 can be located on both sides of the same position of the ear 500 with the main module 1 in the wearing state of the earphone 100, further making at least part of the rear fixing block 23 exert force on both sides of the same position of the ear 500 with the main module 1, improving the stability and support of the wearing, and cooperating with the rear covering section 222 to effectively improve the wearing comfort. 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 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, thereby being able to deform in a more labor-saving manner in the wearing state, in another aspect, the same clamping effect can be maintained to reduce the pressure applied to the user's ear, improving the wearing comfort, on the other hand, better support can be improved, and the rear covering section 222 can be more tightly attached to the ear, further providing better comfort for wearing through the buffering capacity.

[0188] In combination Figure 26 In some embodiments, the rear covering section 222 is provided with a buffer cavity 220, and at least part of the buffer cavity 220 is located at the part of the rear covering section 222 opposite to the free end 102.

[0189] In the wearing state of the earphone 100, at least part of the buffer cavity 220 is located on the two sides of the free end 102 at the same position of the ear 500, further making at least part of the rear covering section 222 and the free end 102 exert force arm equivalence on the two sides of the ear 500 at the same position. 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 stressed, reduce the force acting on the ear 500 between the free end 102 and the rear covering section 222, facilitate the user to wear, and improve the wearing comfort.

[0190] In combination Figure 1 and Figure 26 In some embodiments, the free end 102 is arranged to extend into the concha cavity 502 of the ear 500 in the wearing state, and the free end 102 and the rear covering section 222 are arranged to jointly clamp the area of the ear 500 from the front and rear sides of the area of the ear 500 corresponding to the concha cavity 502 in the wearing state, and the buffer cavity 220 is located at the part of the rear covering section 222 for clamping the area of the ear 500.

[0191] By arranging the free end 102 to extend into the concha cavity 502 of the ear 500 in the wearing state, the ear is facilitated to receive the sound emitted by the earphone 100. In the wearing state of the earphone 100, at least part of the buffer cavity 220 is located on the two sides of the free end 102 at the same position of the ear 500 corresponding to the concha cavity 502, further making the part of the rear covering section 222 for clamping the area of the ear 500 and the free end 102 exert force arm equivalence on the two sides of the ear 500 corresponding to the concha cavity 502. 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 stressed, reduce the force acting on the area of the ear 500 corresponding to the concha cavity 502 between the free end 102 and the rear covering section 222, facilitate the user to wear, and improve the wearing comfort.

[0192] In combination Figure 22 In some embodiments, the buffer cavity 220 is arranged in the shape of a long strip-shaped through hole or 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 covering 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 covering 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 covering section 222 along the extension direction is one-third.

[0193] In this way, the buffer cavity 220 can provide sufficient deformation space for the rear covering section 222, and the rear covering section 222 can maintain good support performance. The buffer cavity 220 facilitates tactile recognition when the earphone is taken off or worn.

[0194] In combination Figure 24 and Figure 25 In some embodiments, the ear hook 2 further comprises a connector 24 fixedly arranged at one end of the elastic framework 21 close to the first end 201, and the connector 24 is fixedly connected with 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 fixed block 23 along the extension direction.

[0195] The connector 24 facilitates the assembly of the ear hook 2 and the host module 1. For example, the ear hook 2 and the host module 1 can be buckled together through 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 fixed block 23 along the extension direction, the connection stability of the ear hook 2 and the host module 1 can be improved. In addition, in this way, the shape precision of the outer periphery of the connector 24 close to the host module 1 can be higher when the ear hook 2 is injection molded, so that the product consistency of the entire ear hook 2 is better.

[0196] In combination Figure 22 , Figure 24 and Figure 25 In some embodiments, the elastic framework 21 is arranged in 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 perpendicular to each other, and the host module 1 is arranged in the ear 500 along the thickness direction Y in the wearing state. The third positioning hole 241 extends along the thickness direction Y.

[0197] By arranging the third positioning hole 241, the connector 24 can be positioned by an external positioning device during the production process of the ear hook 2, so that the deformation of the elastic framework 21 during the production process of the ear hook 2 can be reduced, the shape and position size between the components of the ear hook 2 are more accurate, and the quality yield of the ear hook 2 is improved.

[0198] The connector 24 can be formed by injection molding, and the third positioning hole 241 is formed in the connector 24 by injection molding. By arranging the third positioning hole 241 to extend along the thickness direction Y, the opening direction of the mold is consistent with the direction in which the mold is separated from the third positioning hole 241 during the injection molding process, so that the connector 24 can be easily demolded.

[0199] Further, the third positioning hole 241 is a blind hole, which on one hand can facilitate demolding during injection molding, and on the other hand can make the third positioning hole 241 not penetrate the fixing block 23, so that the fixing block 23 can maintain a high strength.

[0200] In some embodiments, as shown in Figure 14 and Figure 15a , the host module 1 has a length direction X, a width direction Z and a thickness direction Y perpendicular to each other, the host module 1 is used to be stacked along the thickness direction Y on the ear in the wearing state, the extension direction of the elastic framework 21 at one end close to the first end 201 has a first included angle Q1 with the length direction X towards the ear hook 2, and the extension direction of the connector 24 has a second included angle Q2 with the length direction X towards the ear hook 2, the first included angle Q1 is smaller than the second included angle Q2.

[0201] Whether it is a headset 100 or other electronic device 300 such as a computer, a mobile phone, a tablet computer, etc., a charging interface, a data transmission interface, or both, will be provided. The following will exemplarily describe the exemplary content of the electronic device 300 with respect to the interface.

[0202] As shown in Figure 27 , the electronic device 300 can include a battery 14 and an interface circuit 310. Among them, the interface circuit 310 is coupled to the battery 14, so that the external charging device can charge the battery 14 through the interface circuit 310. Among them, the electronic device 300 can be a mobile phone, a computer, a headset device, etc. The external charging device can be a power bank, a charging pile, etc. which can output electric energy to the electronic device 300 through the interface circuit 310.

[0203] In some embodiments, as shown in Figure 7 , Figure 8 and Figure 27 , the electronic device 300 can include a charging box 900 and a headset 100, the charging box 900 contains the headset 100 and is used to charge the headset 100, and the interface circuit 310 can be arranged in the charging box 900, so that the external charging device can charge the charging box 900 through the interface circuit 310, so that the charging box 900 can obtain electric energy from the external charging device, and the charging box 900 can charge the headset 100 when the headset 100 is contained in the charging box 900.

[0204] Exemplarily, as shown in Figure 28As shown, the interface circuit 310 may include a power receiving interface 311 and a preset thermistor 312. The power receiving interface 311 may include an identification pin A5 (B5), which is used by the external charging device to detect the coupling state between the interface circuit 310 and the external charging device when the interface circuit 310 is coupled to the external charging device. The identification pin A5 (B5) continuously transmits the coupling state to the external charging device, enabling the external charging device to monitor the coupling state in real time and react promptly based on the detected coupling state, thus minimizing the risk of safety accidents. In some embodiments, the external charging device may be configured to intermittently detect the coupling state between the interface circuit 310 and the external charging device; for example, the external charging device may detect the coupling state every 5 seconds or 10 seconds, saving energy for both the external charging device and the electronic device 300.

[0205] The preset thermistor 312 can be configured to change the coupling state of the interface circuit 310 detected by the external charging device according to the temperature change of the powered interface 311. For example... Figure 28 As shown, the preset thermistor 312 can be coupled to the identification pin A5 (B5). After detecting a temperature change in the powered interface 311, the preset thermistor 312 further changes the coupling state between the interface circuit 310 and the external charging device according to the temperature of the powered interface 311. 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 for charging through the interface circuit 310, the external charging device can monitor the temperature of the powered interface 311 in a timely manner. This allows for real-time monitoring of the coupling state between the interface circuit 310 and the external charging device, enabling more sensitive responses based on the detected coupling state. This, in turn, protects the electronic device 300 and minimizes the risk of accidents.

[0206] In some embodiments, the power receiving interface 311 can be a Type-C interface, and the identification pin A5 (B5) can be a CC (Configuration Channel) pin. Specifically, the Type-C interface is a USB interface shape standard, which has a smaller size than Type-A and Type-B, and is an interface type that can be applied to both a PC (master device) and an external device (slave device, such as a mobile phone, earphone 100, or charging box 900). The CC pin is mainly used for identifying the type of device inserted into the power receiving interface 311 and for communication, and is also used to confirm the data transmission direction and the plug-in direction. In some embodiments, the CC pin is connected to the preset thermistor 312, so that the external charging device can directly receive the data information related to the coupling state through the CC pin, improve the efficiency of the external charging device in judging the coupling state between 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.

[0207] Of course, in other embodiments, the power receiving interface 311 can be a Type-A or Type-B interface, and the identification pin A5 (B5) can be a VBUS pin or other pin.

[0208] In some embodiments, the resistance value 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 value of the preset thermistor 312 through the identification pin A5 (B5). The preset thermistor 312 can be a sensor resistor, which typically has the characteristic that its resistance value changes according to the temperature change, i.e., its resistance value is different at different temperatures. Therefore, the resistance value of the preset thermistor 312 can directly reflect the temperature change of the power receiving interface 311. By setting the external charging device to directly detect the coupling state between the external charging device and the interface circuit 310 according to the resistance value of the preset thermistor 312, the coupling state obtained by the external charging device can be more accurate.

[0209] In some embodiments, the identification pin A5 (B5) can be grounded through the preset thermistor 312. Specifically, the preset thermistor 312 is arranged between the identification pin A5 (B5) and the ground wire. When the external charging device is connected with the powered interface 311, if the temperature of the preset thermistor 312 is too high to cause the resistance of the preset thermistor 312 to be too high, 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 can approach infinity to disconnect the connection between the external charging device and the ground, so that the external charging device can also judge the coupling condition with the interface circuit 310 by connecting with the ground. Moreover, the preset thermistor 312 is directly connected with the identification pin A5 (B5), so that the preset thermistor 312 can directly detect and reflect the temperature change of the powered interface 311, and is not easily affected by other circuit components, and can also more accurately transmit the coupling state information of the interface circuit 310 and the external charging device to the external charging device.

[0210] In some embodiments, the preset thermistor 312 can be set to a resistance value in a predetermined resistance range, and the coupling state detected by the external charging device is normal, and the resistance value is not in the preset resistance range, and the coupling state detected by the external charging device is abnormal.

[0211] The predetermined resistance range can be set with reference to the temperature threshold of the powered interface 311 in normal working condition, so that the predetermined resistance range can represent the normal working temperature of the powered interface 311 when coupled with the external charging device.

[0212] When the resistance value of the preset thermistor 312 is in the predetermined resistance range, it indicates that the temperature of the powered interface 311 is in a normal temperature, and in the normal temperature, the powered interface 311 can maintain normal power supply, communication and other functions between the powered interface 311 and the external charging device, and further indicates that the external charging device detects that the coupling state between the powered interface 311 and the external charging device is normal.

[0213] When the resistance value of the preset thermistor 312 is not in the preset resistance range, it indicates that the temperature of the powered interface 311 detected by the preset thermistor 312 is in an excessively high temperature, and the powered interface 311 in the excessively high temperature can affect the normal communication or power supply function between the powered interface 311 and the external charging device, so that the external charging device detects that the coupling state is abnormal.

[0214] For example, the preset resistance range can be 4.9KΩ-5.3KΩ. When the preset thermistor 312's resistance is within 4.9KΩ-5.2KΩ, the coupling state detected by the external charging device is normal. When the preset thermistor 312's resistance 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 can also be other values. For example, if different models of thermistors are used, the preset resistance range can also be other resistance ranges corresponding to the thermistors. For example, the preset resistance range can also be 4.7KΩ~5.4KΩ, 5KΩ~5.5KΩ, etc. This application will not specifically list them all here.

[0215] By setting a predetermined resistance range for the preset thermistor 312, the real-time resistance value of the preset thermistor 312 can be detected to reflect the coupling status between the power receiving interface 311 and the external charging device. This allows the external charging device to obtain more accurate detection results, thereby improving the safety of the interface circuit 310.

[0216] In some embodiments, the nominal resistance of the preset thermistor 312 can be 4.8KΩ to 5.4KΩ. This setting allows the preset thermistor 312 to detect a wider operating temperature range, making it more sensitive and thus enabling the external charging device to 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 can also be other resistors corresponding to that thermistor. For example, the nominal resistance of the preset thermistor 312 can also be 4.5KΩ to 5.5KΩ, 4.9KΩ to 5.3KΩ, or other values. This application does not make specific limitations here.

[0217] In some embodiments, the preset thermistor 312 can be configured such that its resistance is within a predetermined resistance range when the temperature of the power receiving interface 311 is within a predetermined temperature range, and its resistance is not within the predetermined resistance range when the temperature of the power receiving interface 311 is not within the predetermined temperature range.

[0218] Specifically, the predetermined temperature range can be referenced to the normal temperature of the powered interface 311 when it is coupled to an external charging device and can perform normal power supply, communication, and other operations. The predetermined resistance range is configured to correspond to the predetermined temperature range. Therefore, if the temperature of the powered 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 powered 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.

[0219] In some implementations, if the operating temperature of the power receiving interface 311 is within the range of 0℃-45℃, the power receiving interface 311 can achieve normal power supply and communication with the external charging device. Therefore, the predetermined temperature range can be set to 0℃-45℃, and the corresponding predetermined resistance range can be set to 4.9KΩ-5.3KΩ. When the coupling state detected by the external charging device is normal, it indicates that the temperature of the power receiving interface 311 is within the predetermined temperature range of 0℃-45℃, the resistance value of the preset thermistor 312 is within the range of 4.9KΩ-5.3KΩ, and the power receiving interface 311 is in normal working condition. However, when the temperature of the power receiving interface 311 is greater than 45℃, the power receiving interface 311 is no longer suitable for receiving power or communication from the external charging device. In this case, the resistance value of the preset thermistor 312 will exceed 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 will be abnormal. In some implementations, 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. 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 will be abnormal.

[0220] Of course, in other embodiments, the predetermined temperature range can be other values, and the predetermined resistance range corresponding to the predetermined temperature range can also be other values, which will not be specifically listed here.

[0221] In the aforementioned embodiments, a predetermined resistance range is set according to the normal operating temperature range of the power receiving interface 311, and the coupling state between the power receiving interface 311 and the external charging device is determined based on this. This enables the external charging device to monitor the temperature of the power receiving interface 311 in a timely manner, promptly grasp any abnormalities in the power receiving interface 311, and react accordingly, thereby improving the operational safety of the interface circuit 310.

[0222] In some implementations, such as Figure 29 As shown, the power receiving interface 311 may include a power supply pin A4 (B4), which can be used to receive the charging voltage output by the external charging device when the interface circuit 310 is coupled with the external charging device. Specifically, the external charging device stops outputting charging voltage to the power supply pin A4 (B4) when it detects an abnormal coupling state.

[0223] In some implementations, the power supply pin A4 (B4) can be a VBUS pin, which can be connected to the pin that outputs the voltage during external charging when the external charging device is coupled to the power receiving 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).

[0224] Specifically, when the external charging device detects an abnormal coupling state, it indicates that the temperature of the power receiving interface 311 exceeds the predetermined temperature range, or that the temperature of the power receiving interface 311 is too hot or too cold. At this time, the external charging device will stop outputting charging voltage to the power supply pin A4 (B4) to protect the power receiving interface 311 and minimize the occurrence of safety accidents.

[0225] In some implementations, such as Figure 29 As shown, there can be two identification pins A5 (B5) and two preset thermistors 312. The two identification pins A5 (B5) and the two preset thermistors 312 correspond one-to-one.

[0226] Setting two identification pins A5 (B5) can enhance the power communication function between the power receiving interface 311 and the external charging device. Setting two preset thermistors 312 can perform dual detection of the temperature of the power receiving interface 311, thereby making the external charging device's detection of the temperature of the power receiving interface 311 more accurate.

[0227] In some implementations, such as Figure 29 As shown, the number of power supply pins A4 (B4) can also be two, namely the first power supply pin A4 (B4) and the second power supply pin A4 (B4).

[0228] In some implementations, such as Figure 29 As shown, the power receiving interface 311 may also include a ground pin, a receive pin, a transmit pin, an arbitrary plug-in pin, and an auxiliary pin.

[0229] The grounding pin is used to connect to the ground wire. For example, the grounding pin can be the GND pin. Optionally, there can be four grounding pins, namely the first grounding pin A1, the second grounding pin A12, the third grounding pin B1, and the fourth grounding pin B12.

[0230] The transmitting pins can include positive transmitting pins and negative transmitting pins. The number of the positive transmitting pins and the negative transmitting pins can also be set to two. The positive transmitting pins include a first positive transmitting pin A2 and a second positive transmitting pin B2, and the negative transmitting pins include a first negative transmitting pin A3 and a second negative transmitting pin B3. The transmitting pins are used for high-speed transmission of data. After the external device is plugged into the receiving electrical interface 311, the transmitting pins are used for high-speed transmission of data to the external device.

[0231] The receiving pins can include positive receiving pins and negative receiving pins. The number of the positive receiving pins and the negative receiving pins can also be set to two. The positive receiving pins include a first positive receiving pin A10 and a second positive receiving pin B10, and the negative receiving pins include a first negative receiving pin A11 and a second negative receiving pin B11. After the external device is plugged into the receiving electrical interface 311, the receiving pins are used for high-speed reception of data transmitted by the external device.

[0232] The arbitrary connecting pins can also include positive arbitrary connecting pins and negative arbitrary connecting pins. For example, the positive arbitrary connecting pins are D+ pins, and the negative arbitrary connecting pins are D- pins. The number of the positive arbitrary connecting pins and the negative arbitrary connecting pins can also be set to two. The positive arbitrary connecting pins include a first positive arbitrary connecting pin A6 and a second positive arbitrary connecting pin B6, and the negative arbitrary connecting pins include a first negative arbitrary connecting pin A7 and a second negative arbitrary connecting pin B7. The arbitrary connecting pins are used for transmission of two groups of signals of USB 2.0. The positive arbitrary connecting pins and the negative arbitrary connecting pins are cross-connected, so that data is connected when the external device is connected in any direction.

[0233] The auxiliary pins are used for transmission of auxiliary signals between the receiving electrical interface 311 and the external charging device in some special modes. The auxiliary pins can be SBU pins. The number of the auxiliary pins can be two, which are a first auxiliary pin A8 and a second auxiliary pin B8.

[0234] The above description is only some embodiments of the present application, and does not limit the protection scope of the present application. Any equivalent device or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
