Technical field

[0002] The present application relates to the technical field of electronic devices, and in particular to headphones. [Background Technology]

[0003] With the increasing popularity of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's expectations of electronic devices are becoming increasingly higher. Electronic devices such as headphones and smart glasses have also become widely used in people's daily lives. They can be used in conjunction with terminal devices such as mobile phones and computers to provide users with an auditory feast. However, the part of current headphones that hangs on the human ear has poor elasticity, which has a negative impact on the user's wearing experience.

[0004] [Summary of the invention]

[0005] The present application provides an earphone, which includes a host module and an ear hook. The ear hook has a first end and a second end arranged opposite to each other, and the first end is connected to the host module. The ear hook is used to be hung on the user's ear. The ear hook includes an elastic frame, a covering and a fixed block, and the elastic frame is extended along the extension direction from the first end to the second end. The covering includes a front covering section and a rear covering section, and the front covering section and the rear covering section are connected to each other in the extension direction. The fixed block is arranged at an end of the elastic frame away from the first end, and the front covering section covers the elastic frame and the fixed block. The rear covering section does not cover the elastic frame and the fixed block, but is located downstream of the fixed block in the extension direction. The extension length of the rear covering section along the extension direction is greater than or equal to the extension length of the fixed block along the extension direction. By providing the elastic frame, the elasticity of the ear hook can be improved. By providing the fixed block, the elastic frame can be prevented from piercing the covering, making it easier to process and shape, and the processing accuracy can be effectively improved.

[0006] In some embodiments, the extension length of the rear covering section along the extension direction is 10-25 mm. And / or the extension length of the front covering section along the extension direction is 35-80 mm. And / or the extension length of the fixing block along the extension direction is 6-15 mm.

[0007] In some embodiments, a ratio of an extension length of the front covering segment along the extension direction to an extension length of the rear covering segment along the extension direction is greater than or equal to 2 and less than or equal to 4.5.

[0008] In some embodiments, an end of the elastic skeleton away from the first end is inserted into the fixing block.

[0009] In some embodiments, the connection between the end surface of the fixing block facing the rear covering section and the peripheral side surface of the fixing block is chamfered or configured as a curved surface.

[0010] In some embodiments, a first positioning hole is formed in the front covering section and / or the rear covering section, and the fixing block can be exposed through the first positioning hole.

[0011] In some embodiments, the first positioning hole is opened on the peripheral side of the front covering section and / or the rear covering section, and the peripheral side of the front covering section and / or the rear covering section is also opened with a groove, and the first positioning hole is opened at the bottom of the groove.

[0012] In some embodiments, the first positioning hole is located at one end of the groove, and the other end of the groove extends toward the second end.

[0013] In some embodiments, the host module has a length, width, and thickness that are perpendicular to each other, and the host module is configured to be stacked on the ear along the thickness direction when worn. The first positioning hole extends along the thickness direction. And / or, the fixing block defines a second positioning hole, and the first positioning hole and the second positioning hole are oppositely disposed and communicate with each other.

[0014] In some embodiments, the first positioning hole is configured as a blind hole, thereby facilitating demoulding, providing a beautiful appearance, and having little effect on the strength of the fixing member.

[0015] In some embodiments, the first positioning hole is provided on the side close to the ear when the earphone is worn, so that the earphone has a neater appearance and is less likely to harbor dirt and grime that would affect the appearance.

[0016] In some embodiments, the earphones further include a functional part, which is detachably connected to the first positioning hole. The functional part may be a lanyard connecting the two earphones, or the like.

[0017] In some embodiments, the hardness of the fixing block is greater than that of the covering member. And / or, the front covering section and the rear covering section are integrally formed, and the front covering section is integrally formed to cover the outer periphery of the elastic frame and the fixing block.

[0018] In some embodiments, the host module includes a connecting end connected to the first end of the ear hook and a free end away from the connecting end, and at least a portion of the rear covering section is arranged opposite to the free end.

[0019] In some embodiments, the host module has a length direction, a width direction, and a thickness direction that are perpendicular to each other, and the host module is configured to be stacked on the ear along the thickness direction when worn. The width dimension of the rear covering section is greater than the width dimension of the host module.

[0020] In some embodiments, the host module has an inner side surface facing the ear and an outer side surface facing away from the ear along the thickness direction when worn, and an upper side surface and a lower side surface connecting the inner side surface and the outer side surface, wherein the upper side surface and the lower side surface are spaced apart in the width direction. The second end is located in the rear covering section, and the rear covering section extends beyond the lower side surface in the width direction.

[0021] In some embodiments, at least a portion of the fixing block is located between the extended planes of the upper and lower sides, and the fixing block extends 6-15 mm along the ear hook's extension direction. This arrangement creates a larger lever arm along the length of the host module and reduces titanium wire length, thereby reserving space for components such as the cover (e.g., the rear cover section).

[0022] In some embodiments, a buffer cavity is defined in the rear covering segment, and at least a portion of the buffer cavity is located at a portion of the rear covering segment opposite to the free end.

[0023] In some embodiments, the free end is configured to extend into the concha cavity of the ear when worn, and the free end and the rear covering section are configured to jointly clamp the ear area from the front and back sides of the ear area corresponding to the concha cavity when worn, and the buffer cavity is located in the part of the rear covering section used to clamp the ear area.

[0060] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0062] In conjunction with Figure 1 , the user's ear 500 may include physiological parts such as the external auditory canal 501, the cavum concha 502, the cymba concha 503, the triangular fossa 504, the antihelix 505, the scaphoid 506, the helix 507, and the tragus 508. Although the external auditory canal 501 has a certain depth and extends to the eardrum, for ease of description and in conjunction with Figure 1 , unless otherwise specified, the external auditory canal 501 specifically refers to its entrance away from the eardrum (i.e., the ear canal). Furthermore, physiological parts such as the cavum concha 502, the cymba concha 503, and the triangular fossa 504 have a certain volume and depth; and the cavum concha 502 is directly connected to the external auditory canal 501, which can be simply regarded as the aforementioned ear canal being located at the bottom of the cavum concha 502.

[0063] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. In order to facilitate description and reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears 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 earphones 100", "the earphones 100 are in a wearing state" and "in a wearing state" may refer to the earphones 100 described in this application being worn on the ears of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphones 100 worn by different users and the earphones 100 worn on the ears of the aforementioned simulator, but such differences should be tolerated.

[0064] 2 to 5 , the earphone 100 may include a host module 1 and an ear hook 2. The host module 1 may include a shell assembly 10 and a speaker 13. The host module 1 may also include a battery 14. The ear hook 2 may be hook-shaped, and the earphone 100 may be worn on the user's ear via the ear hook 2. The ear hook 2 may be connected to the shell assembly 10. In the worn state, the shell assembly 10 is located on the front side of the ear, and the ear hook 2 is at least partially located on the back side of the user's ear, so that the earphone 100 is hung on the ear. In addition, the shell assembly 10 may be used to form an accommodating space 101. The speaker 13 may be arranged in the accommodating space 101 to provide air-conducted sound to the external auditory canal of the user's ear. The battery 14 may also be arranged in the accommodating space 101.

[0065] To facilitate description of the shape of the housing assembly 10, this application defines the housing assembly 10 as having a first direction X and a second direction Y, wherein the first direction X may be orthogonal to the second direction Y (see FIG5 ). The first direction X may refer to the length direction of the housing assembly 10, and the second direction Y may refer to the thickness direction of the housing assembly 10.

[0066] The housing assembly 10 is positioned in front of the user's ear along the second direction Y. The housing assembly 10 further comprises a first end 102 and a second end 103 disposed opposite each other along the first direction X. The first end 102 may refer to the portion facing the user's cavum concha 502 during wear, while the second end 103 may refer to the portion further away from the user's cavum concha 502 relative to the first end 102. The second end 103 may be connected to the ear hook 2 and will be referred to as the connecting end 102 hereinafter, while the first end 102 may also be referred to as the free end 103 hereinafter.

[0067] The first end 102 of the housing assembly 10 at least partially extends into the cavum conchae 502 of the user's ear, leaving the user's external auditory canal open. The user's external auditory canal being open means that the housing assembly 10 does not completely block the external auditory canal. Furthermore, due to individual differences between users, when the earphone 100 is worn by different users, the housing assembly 10 may partially block the external auditory canal, but the external auditory canal may still not be completely blocked.

[0068] In summary, when a user wears the earphones 100, the earhook 2 is positioned on the user's ear and partially behind the user's ear. The housing assembly 10 is positioned in front of the user's ear, and the second end 103 of the housing assembly 10 can extend into the user's cavum concha 502. Furthermore, the earhook 2 can be connected to the second end 103 of the housing assembly 10, or a portion near the second end 103. Due to the shape of the ear, the shape of the earhook 2, and the installation position of the first end 102 of the housing assembly 10, the second end 103 of the housing assembly 10 is typically positioned in front of, above, or above-front of the first end 102 when the earphones are worn.

[0069] Optionally, the battery 14 can power the speaker 13. Optionally, when worn, the first end 102 is closer to the cavum concha 502 of the user's ear than the second end 103, and the speaker 13 is positioned closer to the first end 102, while the battery 14 is positioned closer to the second end 103. In this case, the speaker 13 is more likely to emit air-conducted sound toward the user's external auditory canal.

[0070] Optionally, the speaker 13 and the battery 14 are spaced apart in the accommodating space 101 along the first direction X. In this case, the speaker 13 and the battery 14 can be assembled in the housing assembly 10 at the same time, thereby improving assembly efficiency and reducing the use of wires.

[0071] Optionally, the housing assembly 10 may have a partition wall 104 for separating the speaker 13 from the battery 14. In this case, the partition wall 104 may separate the battery 14 from the speaker 13, reducing the possibility of water vapor in the speaker 13 contaminating the battery 14.

[0072] 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 ears in the worn state. In the reference plane defined by the first direction X and the second direction Y. The positive direction of the first axis ZX1 and the projection of the second axis ZX2 in the reference plane are arranged 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 center of gravity of the speaker 13, the geometric center of its end face (such as a circular end face, a runway-shaped end face) or the axis of the centroid. The second axis ZX2 can refer to the axis of symmetry of the battery 14, the axis through the geometric center or the centroid of its two end faces.

[0073] In this case, the speaker 13 and the battery 14 are arranged relative to each other at an angle, which is beneficial to reducing the length of the shell assembly 10 in the first direction X compared to arranging the speaker 13 and the battery 14 side by side, so that the shell assembly 10 can be stably supported when worn and can extend into the concha cavity 502.

[0074] Optionally, the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 projected onto the reference plane is an acute angle. Optionally, the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 projected onto the reference plane is located on the side of the housing assembly 10 facing the user's ear. Optionally, the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 is between 10° and 14°, or between 11° and 14°.

[0075] In this case, the speaker 13 is tilted relatively greatly relative to the battery 14 , and the projected length of the speaker 13 in the first direction X gradually decreases, which is beneficial to reducing the length of the housing assembly 10 in the first direction X.

[0076] Optionally, on the reference plane, the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, the second direction Y has a positive direction pointing to the user's ear, and the intersection angle θ between the projection of the positive direction of the first axis ZX1 in the reference plane and the positive direction of the second direction Y is greater than the intersection angle θ between the projection of the positive direction of the second axis ZX2 in the reference plane and the positive direction of the second direction Y. Optionally, the second axis ZX2 is arranged parallel to the second direction Y. The radial dimension of the speaker 13 may refer to its length in a cross section on the reference plane that is perpendicular to its first axis ZX1. The radial dimension of the battery 14 may refer to its length in a cross section on the reference plane that is perpendicular to its second axis ZX2.

[0077] In this case, because the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, when the speaker 13 is arranged at an angle relative to the second direction Y, the degree of change in its projected length in the first direction X is greater than when the battery 14 is arranged at an angle relative to the second direction Y, thereby facilitating a reduction in the length of the housing assembly 10 in the first direction X. Furthermore, when the speaker 13 is tilted relative to the battery 14, while the second end 103 of the speaker 13 (where the battery 14 is disposed) is in contact with the skin in front of the user's tragus 508, the diaphragm of the speaker 13 can be generally oriented toward the user's external auditory canal, thereby facilitating sound transmission from the speaker 13 toward the user's external auditory canal.

[0078] Optionally, the headset 100 further includes a circuit board 15 disposed in the accommodating space 101. The circuit board 15 controls the speaker 13 to vibrate and produce sound when powered by the battery 14. In addition, the circuit board 15 may also have a radio frequency module for communicating with a mobile terminal.

[0079] Optionally, the circuit board 15 is disposed in the housing assembly 10 and is located on a side of the speaker 13 and battery 14 facing away from the user's ear, and its projection along the second direction Y overlaps with the speaker 13 and battery 14. The overlap of the projection of the circuit board 15 with the speaker 13 and battery 14 may be partial or complete. In this case, the speaker 13 can be disposed on the side closer to the user's ear, which facilitates sound transmission to the user's ear.

[0080] Specifically, the shell assembly 10 includes a first shell 111 and a second shell 112 that match each other along the second direction Y. The first shell 111 is located on the side of the second shell 112 that is away from the user's ear. The speaker 13 and the battery 14 can be fixed to the first shell 111. When worn, the first shell 111 is closer to the user's ear than the second shell 112, and the circuit board 15 is fixed to the second shell 112. In this case, it can facilitate the assembly and disassembly of the earphone 100. Optionally, the circuit board 15 is fixed to the second shell 112 of the shell assembly 10 by hot melting.

[0081] Referring to Figure 6, the headset 100 optionally further includes a charging port 16 disposed on the first housing 111 and a magnetic element 17 disposed between the battery 14 and the first housing 111 along the second axis ZX2. In this case, the headset 100 can be used in conjunction with a charging box having a magnetic charging function. The charging port 16 can extend through the outer wall LS2 of the first housing 111 and be exposed through the outer wall LS2 for contact charging.

[0082] 7 , the charging box 900 may include a lower housing component 910 and an upper housing component 920. The lower housing component 910 may be provided with two contoured grooves 911 for respectively accommodating the earphones 100. The upper housing component 920 may cover the lower housing component 910 to close the contoured grooves 911.

[0083] Furthermore, the charging box 900 may include a main control circuit board arranged in the lower shell assembly 910 and electrode terminals 912 arranged on the main control circuit board. Among them, the electrode terminals 912 can be provided in multiple groups according to needs, for example, two groups. Accordingly, when any earphone 100 is placed in the charging box 900, the charging interface 16 in the earphone 100 can be in one-to-one contact with the electrode terminals 912 in the charging box 900 to meet the requirements of charging, detection and other functions. Accordingly, the electrode terminals 912 may include a positive power supply terminal and a negative power supply terminal, and may further include a detection terminal; the lines connecting them may form a triangle, such as an equilateral triangle, or they may be arranged at intervals along a straight line, for example, spaced apart from each other and collinear.

[0084] Optionally, the electrode terminals 912 may be exposed in the contoured groove 911 . When the earphone 100 is received in the contoured groove 911 , the charging port 16 is electrically connected to the electrode terminals 912 .

[0085] In addition, the charging box 900 may include a magnetic structure (not shown) disposed within the lower shell assembly 910. The magnetic structure may be provided in multiple groups, for example, two groups, as required. After any earphone 100 is placed in the contoured groove 911, the magnetic structure and the magnetic element 17 within the earphone 100 may form a magnetic pairing, so that the charging port 16 and the electrode terminal 912 are in one-to-one contact.

[0086] Several exemplary structures of the ear hook 2 of the headset 200 are shown below. Different exemplary structures can also be combined with each other to obtain other exemplary structures belonging to this embodiment that are not described in detail.

[0087] In order to improve the wearing comfort of the ear hook 2, see the first example structure of the ear hook 2 below:

[0088] As shown in Figure 8, the headset 100 may include a host module 1 and an ear hook 2. The ear hook 2 is curved and has a first end 201 and a second end 202 remote from the first end 201. The first end 201 is connected to the host module 1. The ear hook 2 is used to hang on the user's ear and includes an elastic frame 21 and a covering 22. The elastic frame 21 extends along the extension direction of the ear hook 2. The covering 22 covers the elastic frame 21 and is provided with a buffer cavity 220.

[0089] By providing an ear hook 2 including an elastic skeleton 21 and a covering 22, wherein both the elastic skeleton 21 and the covering 22 have certain elastic limits and can undergo elastic deformation within their respective elastic limits, the user can elastically deform the ear hook 2 to fit the ear when wearing the earphone 100, thereby effectively improving the wearing comfort and stability. Providing a buffer cavity 220 in the covering 22 can make it easier for the covering 22 to undergo elastic deformation when the user wears the earphone 100, and can adapt to different ear widths, thereby better fitting the user's ear and achieving an adaptive function. Moreover, due to the presence of the buffer cavity 220, the contact area between the covering 22 and the user's ear can be increased when the covering 22 contacts the ear, reducing the pressure exerted by the covering 22 on the ear, and improving the user's wearing comfort.

[0090] Furthermore, as shown in FIG. 8 , in the first end 201 and the second end 202 , the buffer cavity 220 is closer to the second end 202 .

[0091] The second end 202 is farther away from the main module 1 than the first end 201. The buffer cavity 220 is set at a position closer to the second end 202. When the user wears it, the part close to the second end 202 can be more easily elastically deformed than the part close to the first end 201. While ensuring the connection stability between the main module 1 and the ear hook 2, the adaptability of the ear hook 2 is improved, effectively improving the wearing comfort of the user.

[0092] Furthermore, as shown in FIG. 9 , the covering member 22 has a rear covering section 222 located at the rear side of the ear when worn, the second end 202 is located at the rear covering section 222 , and the buffer cavity 220 is opened in the rear covering section 222 .

[0093] When the earphone 100 is in the wearing state, the ear hook 2 is hung on the user's ear around the outer circumference of the ear, and the rear covering section 222 is located on the back side of the ear. Opening the buffer cavity 220 in the rear covering section 222 can increase the deformation range of the rear covering section 222, so as to better adapt to the use of users with different ear widths, effectively reduce the pressure exerted by the ear hook 2 on the back side of the user's ear, and provide the user with a better wearing experience.

[0094] Optionally, as shown in Figure 9, the host module 1 includes a connecting end 103 connected to the first end 201 of the ear hook 2 and a free end 102 away from the connecting end 103, at least a portion of the rear covering section 222 is arranged opposite to the free end 102, and at least a portion of the buffer cavity 220 is located in the portion of the rear covering section 222 that is arranged opposite to the free end 102.

[0095] At least a portion of the rear covering section 222 is arranged opposite to the free end 102, and at least a portion of the buffer cavity 220 is located in the portion of the rear covering section 222 that is arranged opposite to the free end 102, so that when the user wears the earphones 100, the rear covering section 222 and the free end 102 are respectively located on both sides of the ear, and the rear covering section 222 located on the back side of the ear can adaptively undergo elastic deformation, effectively reducing the pressure applied to the user's ear when wearing, thereby improving the user's wearing comfort.

[0096] Furthermore, as shown in Figures 8 and 9, the free end 102 is configured to extend into the concha cavity 502 of the ear when worn, and the free end 102 and the rear covering section 222 are configured to jointly clamp the ear area from the front and back sides of the ear area corresponding to the concha cavity 502 when worn, and the buffer cavity 220 is located in the part of the rear covering section 222 for clamping the ear area.

[0097] When the earphone 100 is worn, the free end 102 extends into the concha cavity 502, allowing the rear covering section 222 and the free end 102 to clamp against the front and rear sides of the user's ear. This increases wearing stability and reduces the likelihood of the earphone 100 falling. The portion of the rear covering section 222 that clamps the ear is where relatively greater pressure is applied to the user's ear. Placing the buffer chamber 220 there mitigates the pressure exerted by the rear covering section 222 on the ear, improving the user's wearing experience.

[0098] Optionally, as shown in Figures 8 and 9 , the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to one another. When worn, the host module 1 is configured to be stacked on the ear along the thickness direction Y. The orthographic projection of the buffer cavity 220 on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane.

[0099] The buffer cavity 220 is arranged so that its orthographic projection on a reference plane perpendicular to the longitudinal direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane, that is, the free end 102 and at least a portion of the rear covering section 222 where the buffer cavity 220 is located are relatively clamped on both sides of the ear, so that excessive pressure is not applied when clamping the user's ear, thereby ensuring the fit while improving comfort.

[0100] Optionally, as shown in Figures 9 and 10, the host module 1 has an inner side surface IS facing the ear and an outer side surface OS facing away from the ear along the thickness direction Y when worn, as well as an upper side surface US and a lower side surface LS2 connecting the inner side surface IS and the outer side surface OS, the upper side surface US facing the ear hook 2, and the upper side surface US and the lower side surface LS2 are spaced apart in the width direction Z. The covering member 22 is divided into a front covering section 221 and a rear covering section 222 by the extension plane of the upper side surface US, the first end 201 is located in the front covering section 221, the second end 202 is located in the rear covering section 222, and the buffer cavity 220 is opened in the rear covering section 222.

[0101] The ear hook 2 is arc-shaped and surrounds the main module 1 to locate and fix the main module 1 relative to the user's ear when the user wears it. The size and width of each person's ear are different. The rear covering section 222 arranged opposite to the free end 102 has a larger deformable range due to the buffer cavity 220, so that it can better fit the user's ear when clamping the user's ear, increase the contact area between the rear covering section 222 and the ear, and will not apply excessive pressure to cause discomfort to the user, effectively improving the user's experience.

[0102] Furthermore, as shown in FIG. 9 , a dimension T5 of the buffer cavity 220 in the width direction Z is greater than a dimension T2 of the host module 1 in the width direction Z.

[0103] The buffer cavity 220 is set to have a dimension T5 in the width direction Z that is larger than the dimension T2 of the main module 1 in the width direction Z, so that the buffer cavity 220 has sufficient deformation space to allow the rear covering section 222 to be easily deformed, so that the rear covering section 222 can better fit the structure of the ear when clamping the user's ear, and it is also more convenient for the user to adjust the wearing.

[0104] Optionally, as shown in Figure 9, the covering part 22 includes a front covering section 221 and a rear covering section 222, the front covering section 221 is covered on the elastic skeleton 21, the front covering section 221 and the rear covering section 222 are connected in sequence in the extension direction, the rear covering section 222 does not cover the elastic skeleton 21, and the buffer cavity 220 is formed in the rear covering section 222.

[0105] The stiffness of the elastic skeleton 21 can be greater than the stiffness of the covering member 22, so that the elastic skeleton 21 can support and maintain the relative shape of the ear hook 2. The front covering section 221 is covered on the elastic skeleton 21, so that the user's ear does not directly contact the elastic skeleton 21. While maintaining the relative shape of the ear hook 2, it protects the user's ear and improves the user's comfort. In addition, the rear covering section 222, which clamps the ear together with the free end 102, does not cover the elastic skeleton 21. That is, the rear covering section 222 can be located downstream of the elastic support member in the direction extending from the first end 201 to the second end 202, making it easier for the rear covering section 222 to undergo elastic deformation relative to the front covering section 221, thereby increasing the comfort when fitting with the user's ear. On this basis, the buffer cavity 220 is formed in the rear covering section 222, so that the rear covering section 222 has a larger elastic range and can achieve greater elastic deformation to adapt to different ear widths, thereby improving the applicability and usability of the earphone 100. Optionally, the material of the covering 22 may include elastic non-metallic materials such as silicone or rubber, and the material of the elastic skeleton 21 may include metal materials or non-metallic materials, such as titanium wire, steel wire or elastic plastic parts, etc., which are not limited here.

[0106] Optionally, as shown in Figure 9, the ear hook 2 includes a fixed block 23, which is fixedly arranged at one end of the elastic skeleton 21 close to the second end 202, the front covering section 221 covers the fixed block 23, and the extension length D2 of the rear covering section 222 along the extension direction is greater than the extension length D4 of the fixed block 23 along the extension direction.

[0107] The fixing block 23 is fixedly disposed at one end of the elastic frame 21 near the second end 202, and the front covering section 221 covers the fixing block 23, thereby improving the stability of the fixation between the front covering section 221 and the elastic frame 21. The extension length D2 of the rear covering section 222 along the extension direction is greater than the extension length D4 of the fixing block 23 along the extension direction, so that the rear covering section 222 has a larger extension length, which can provide sufficient contact area when worn by the user, ensuring the user's wearing comfort. Because the rear covering section 222 and the front covering section 221 may bend relative to each other when the ear hook 2 undergoes elastic deformation, the provision of the fixing block 23 can effectively reduce the possibility of the elastic frame 21 puncturing the rear covering section 222, thereby increasing the service life of the earphone 100.

[0108] Optionally, the ratio of the extension length D2 of the rear covering section 222 along the extension direction to the extension length D1 of the front covering section 221 along the extension direction is greater than or equal to one-fifth and less than or equal to one-half, so that the rear covering section 222 has a sufficient contact area with the user's ear when the earphone 100 is worn, and the elastic skeleton 21 covered by the front covering section 221 can provide sufficient supporting strength to maintain the relative shape of the ear hook 2, thereby improving the aesthetics and service life of the earphone 100.

[0109] Optionally, the extension length D1 of the front covering section 221 along the extension direction is 50 to 70 mm. If this value is too small, the ear of the user may be greatly squeezed when wearing the earphones, resulting in poor wearing comfort. If this value is too large, the ear hook 2 may not be able to properly grip the ear of the user when wearing the earphones 100, resulting in an unstable fit.

[0110] Optionally, the extended length D2 of the rear covering section 222 is 10 to 30 mm. Within this length range, the ear hook 2 can be both comfortable and aesthetically pleasing, thereby enhancing the user's experience. If this value is too large, it may extend beyond the user's ear area when worn, adversely affecting both convenience and aesthetics. If this value is too small, the area and length required to clamp the user's ear are too small, making it difficult to properly clamp the ear, resulting in an unstable fit.

[0111] Optionally, as shown in Figures 11a and 12, the ear hook 2 further includes a connector 24, which is fixedly disposed at an end of the elastic frame 21 near the first end 201. The connector 24 is plugged and fixed to the host module 1. The ear hook 2 is plugged and fixed to the host module 1 via the connector 24, effectively improving the connection stability between the ear hook 2 and the host module 1 and facilitating assembly and disassembly.

[0112] 13 , the buffer cavity 220 is enclosed and formed inside the cover 22. The enclosed buffer cavity 220 can effectively prevent impurities such as dust and grease from entering the buffer cavity 220 and damaging the buffer cavity 220, thereby effectively extending the service life of the cover 22.

[0113] Optionally, as shown in FIG8 , the buffer cavity 220 is configured in a hole-like or groove-like shape to better accommodate the elastic deformation of the cover 22 and enhance wearing comfort for the user. In some embodiments, the buffer cavity 220 is configured in a hole-like shape and extends through the cover 22 along the thickness direction Y. In other embodiments, the buffer cavity 220 is configured in the shape of an elongated, curved through-hole, and the curvature of the buffer cavity 220 matches the curvature of the portion of the cover 22 where the buffer cavity 220 is located.

[0114] Optionally, as shown in Figure 14, the number of buffer cavities 220 is at least two, and at least two buffer cavities 220 are spaced apart along the extension direction of the ear hook 2, so that the covering part 22 has a sufficient elastic range, which improves the user's wearing comfort while effectively reducing the possibility of damage due to the excessive width of the user's ear, thereby improving the service life of the ear hook 2.

[0115] Optionally, as shown in Figure 11a, the ear hook 2 also includes a filling piece 25, the hardness of the filling piece 25 is less than the hardness of the covering piece 22, and the filling piece 25 is arranged in the buffer cavity 220, so as to provide certain support for the covering piece 22 without affecting the elastic deformation of the covering piece 22, thereby improving the service life of the covering piece 22 and thus improving the service life of the ear hook 2.

[0116] Optionally, the cover 22 has an inner side facing the host module 1 and an outer side facing away from the inner side, with the inner side being closer to the buffer cavity 220 than the outer side. The inner side of the cover 22 is the side that contacts the user's ear, and the buffer cavity 220 is closer to the inner side, which can achieve a better fit and softness of the cover 22 when worn by the user, thereby improving user comfort.

[0117] In the examples shown in Figures 9 and 13 above, the elastic skeleton 21 and the buffer cavity 220 are spaced apart or adjacent to each other in the extension direction of the ear hook 2. In the examples shown in Figures 15a and 15b, 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 that is perpendicular to the extension direction of the elastic skeleton 21 and passes through the buffer cavity 220, and the buffer cavity 220 is spaced apart from the elastic skeleton 21 in the preset radial direction. With such a configuration, on the basis of the wearing comfort provided by the buffer cavity 220, the elastic skeleton 21 can provide better support strength at the position of the buffer cavity 220, thereby providing higher wearing stability.

[0118] Specifically, the buffer cavity 220 is closer to the main module 1 in a predetermined radial direction than the elastic frame 21, so that the buffer cavity 220 is closer to the ear when worn. Through this arrangement, the buffer cavity 220 can provide elastic cushioning when fitting against the user's ear, achieving a better fit and softness, thereby improving wearing comfort.

[0119] Specifically, the covering member 22 includes a first covering portion 2201 and a second covering portion 2202 located on either side of the buffer cavity 220 along a predetermined radial direction. The first covering portion 2201 and the second covering portion 2202 are spaced apart to form the buffer cavity 220. The first covering portion 2201 is closer to the main module 1 than the second covering portion 2202, thereby contacting the ear. As a result, the first covering portion 2201 is further away from the elastic frame 21, and the buffer cavity 220 provides more space for the first covering portion 2201 to deform, thereby allowing the first covering portion 2201 to more effectively fit the ear and provide a softer fit, effectively improving wearing comfort.

[0120] In an example shown in Figure 15a, the elastic skeleton 21 can be passed through the second covering portion 2202. Optionally, the elastic skeleton 21 extends from the first end of the ear hook 2 to the second end 202 of the ear hook 2. This can provide the ear hook 2 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 it is not easy to puncture the covering part 22 when the covering part 22 is bent, thereby improving the service life. Optionally, the buffer cavity 220 is closer to the second end 202 of the ear hook 2 than the first end 201 and the second end 202 of the ear hook 2.

[0121] In some embodiments, the elastic skeleton 21 further extends to 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 direction in which the ear hook 2 extends from its first end 201 to the second end 202. In other words, the elastic skeleton 21 can extend between the end positions of the buffer cavity 220 and the second end 202. Such an arrangement can provide better support. In other embodiments, the fixing block 23 can be connected to one end of the elastic skeleton 21 extending toward the second end 202 of the ear hook 2, and the fixing block 23 bends and extends from the elastic skeleton 21 to one side of the buffer cavity 220, and bends and extends to 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 direction in which the ear hook 2 extends from its first end 201 to the second end 202. In other words, the fixing block 23 can extend to between the end positions of the buffer cavity 220 and the second end 202. Such an arrangement can not only provide better support, but also make it difficult for the covering 22 to be punctured by the elastic skeleton 21.

[0122] In some embodiments, the end of the elastic skeleton 21 near the second end 202 is inserted into the fixing block 23, and the circumferential dimension of the end of the fixing block 23 away from the elastic skeleton 21 is larger than the circumferential dimension of the end of the fixing block 23 connected to the elastic skeleton 21. By inserting the elastic skeleton 21 into the fixing block 23 to achieve the connection between the elastic skeleton 21 and the fixing block 23, it is beneficial to improve the stability of the connection between the two, and will not affect the support provided by the elastic skeleton 21 for the ear hook 2. In addition, the circumferential dimension of the end of the fixing block 23 away from the elastic skeleton 21 is larger than the circumferential dimension of the end connected to the elastic skeleton 21, which helps to reduce the difficulty of the production process of the fixing block 23 while achieving the bending and extension of the fixing block 23, and is beneficial to improving the strength and service life of the fixing block 23. The fixing block 23 can also have a larger contact area with the covering 22, which is beneficial to reducing the difficulty of processing the ear hook 2 and improving the service life of the ear hook 2.

[0123] Optionally, as shown in Figures 11b and 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 frame 21, and the first positioning hole 223 and the second positioning hole 231 are arranged relative to each other. The relative arrangement of the first positioning hole 223 and the second positioning hole 231 allows an external positioning device to position the fixing block 23 through the first positioning hole 223, making the shape and position dimensions of the various components of the ear hook 2 more precise, which is conducive to improving the yield rate of the ear hook 2. In addition, based on the fact that the circumferential dimension of the end of the fixing block 23 away from the elastic frame 21 is larger than the circumferential dimension of the plugged end, the aperture of the second positioning hole 231 can also be relatively increased, making it easier for the external positioning device to operate and align.

[0124] In some embodiments, as shown in FIG15a , the end of the elastic skeleton 21 close to the first end 201 is inserted into the connector 24, and the extension direction of the end of the elastic skeleton 21 close to the first end 201 intersects with the extension direction of the connector 24. Such a setting can simultaneously achieve a stable connection between the connector 24 and the host module 1 and a stable connection between the elastic skeleton 21 and the connector 24, which is beneficial to improving the connection stability between the elastic skeleton 21 and the connector 24, as well as improving the connection stability between the ear hook 2 and the host module 1.

[0125] Optionally, as shown in Figures 14 and 15a, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. The host module 1 is configured to be superimposed on the ear along the thickness direction Y when worn. The extension direction of the elastic frame 21, located near the first end 201, forms a first angle Q1 with the length direction X, toward the earhook 2. The extension direction of the connector 24 forms a second angle Q2 with the length direction X, toward the earhook 2. The first angle Q1 is smaller than the second angle Q2. By setting the first angle Q1 and the second angle Q2 to two different angles, the elastic frame 21 and the connector 24 intersect with each other. By properly setting the first angle Q1 and the second angle Q2, the end of the elastic frame 21 connected to the connector 24 is brought closer to the center of the cross-section of the earhook 2 while ensuring the stability of the connection between the connector 24 and the host module 1. This facilitates the elastic frame 21 to provide good support for the earhook 2, thereby improving the usability and service life of the earphone 100. Optionally, the first angle Q1 is 70° to 110°, for example, 80°, 85°, 90°, 95°, 100°, etc., and the second angle Q2 is 90° to 130°, for example, 100°, 105°, 110°, 115°, 120°, etc.

[0126] In another example shown in Figure 15b, the elastic skeleton 21 can extend to the second covering portion 2202. Optionally, the ear hook 2 includes a fixed block 23, which is arranged at one end of the elastic skeleton 21 close to the second end 202, and the covering member 22 is covered on the fixed block 23. The fixed block 23 is located on the side of the buffer cavity 220 away from the main module 1, that is, the fixed block 23 can be located in the second covering portion 2202. Through such a setting, the side of the buffer cavity 220 close to the main module 1 can increase the fitting area with the user's ear by deformation when worn, reduce the pressure on the ear, and fit the user's ear more comfortably, on the one hand improving the wearing comfort, and on the other hand such deformation buffering can achieve elastic fit to the human ear, thereby enhancing the wearing stability. Furthermore, the positioning of the fixing block 23 and the portion of the elastic frame 21 on the side of the buffer cavity 220 away from the main module 1 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. Furthermore, the fixing block 23 reduces the possibility of the elastic frame 21 puncturing the second covering portion 2202, thereby improving the stability and reliability of the covering 22.

[0127] Optionally, the fixing block 23 is located between the two ends of the buffer cavity 220 along the extension direction of the ear hook 2, and is closer to the end of the buffer cavity 220 closer to the second end 102. In this way, the buffer cavity 220 can be more largely surrounded in the extension direction of the ear hook 2, which can effectively provide stronger support for the buffer cavity 220 to allow for greater deformation and better fit to the ear. It can also provide stronger support for the entire ear hook 2, ensuring the supporting performance of the entire ear hook 2.

[0128] In order to improve the wearing comfort of the ear hook 2, see the second example structure of the ear hook 2 below:

[0129] As shown in Figure 16, the headset 100 may include a host module 1 and an ear hook 2. The ear hook 2 is connected to the host module 1. The ear hook 2 includes a connecting body 20 and an elastic buffer 26. The connecting body 20 is connected to the host module 1, and the elastic buffer 26 is connected to the connecting body 20. The connecting body 20 forms a first portion of the outer surface of the ear hook 2, and the elastic buffer 26 forms a second portion of the outer surface of the ear hook 2, with at least a portion of the second portion of the outer surface facing the host module 1. The elastic buffer 26 has a lower hardness than the connecting body 20.

[0130] By providing an ear hook 2 comprising a connecting body 20 and an elastic buffer portion 26, the elastic buffer portion 26 has a certain elastic limit and can undergo elastic deformation within this limit. This allows the ear hook 2 to elastically deform to fit the ear when the user wears the headset 100, effectively improving wearing comfort and stability. The elastic buffer portion 26 has a lower hardness than the connecting body 20, and at least a portion of the outer surface of the second portion of the elastic buffer portion 26 facing the host module 1 can directly contact the ear when the user wears the headset 100. The relatively harder connecting body 20 provides support, ensuring the aesthetics of the ear hook 2 while effectively improving wearing comfort.

[0131] Optionally, the elastic buffer portion 26 is detachably connected to the connecting body 20. By providing the elastic buffer portion 26 and the connecting body 20 as two detachably connected parts, production and assembly are facilitated, and when a component is damaged, it can be replaced separately, thereby improving user convenience and extending the service life of the earphone 100.

[0132] Optionally, the elastic buffer portion 26 and the connecting body 20 can be slidably connected to facilitate the installation and disassembly between the elastic buffer portion 26 and the connecting body 20, thereby improving the assembly efficiency and disassembly efficiency of the ear hook 2, and facilitating the subsequent separate replacement of the elastic buffer portion 26 or the connecting body 20.

[0133] In some embodiments, as shown in Figure 17, the elastic buffer portion 26 is provided with a sliding edge 261, and the connecting body 20 is provided with a sliding groove 203. The sliding edge 261 can be slidably embedded in the sliding groove 203, effectively fixing the elastic buffer portion 26 and the connecting body 20, and facilitating installation and disassembly.

[0134] In some embodiments, the elastic buffer portion 26 is bonded or magnetically connected to the connection body 20. Bonding and magnetic connection structures are simple, easy to install and remove, and do not require additional structures to achieve the connection between the elastic buffer portion 26 and the connection body 20, effectively saving production costs and reducing subsequent maintenance costs.

[0135] 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. The host module 1 is used to be stacked on the user's ear when worn, and at least part of the outer surface of the second part is arranged opposite to the free end 102.

[0136] The connection end 103 of the host module 1 is connected to the ear hook 2, and the free end 102 is arranged relative to at least a portion of the outer surface of the second part of the elastic buffer portion 26, so that when the user wears the earphones 100, the free end 102 and at least a portion of the outer surface of the second part are clamped on both sides of the ear, and the elastic buffer portion 26 can adaptively undergo elastic deformation to facilitate wearing by users with different ear sizes, while ensuring the wearing stability of the earphones 100, effectively improving the adaptability of the earphones 100.

[0137] Optionally, as shown in Figures 18 and 19, the extension length D3 of the elastic buffer portion 26 along the extension direction of the ear hook 2 is greater than or equal to one third of the extension length D0 of the ear hook 2 along the extension direction. Then, the elastic buffer portion 26 has sufficient contact length with the user's ear when worn by the user, thereby increasing the contact area between the elastic buffer portion 26 and the ear, thereby better fitting the ear and improving the user's wearing comfort.

[0138] Optionally, as shown in Figure 17, in a partial section along the extension direction of the ear hook 2, an elastic buffer portion 26 and a connecting body 20 can be simultaneously provided in the same cross-section perpendicular to the extension direction of the ear hook 2, and the ratio of the circumferential dimension R1 of the outer edge of the elastic buffer portion 26 to the circumferential dimension R2 of the outer edge of the connecting body 20 is greater than or equal to 0.2 and less than 1. Therefore, while the connecting body 20 provides sufficient support for the ear hook 2 to ensure the relative shape of the ear hook 2, the elastic buffer portion 26 with lower hardness can reduce the discomfort caused by the pressure applied by the ear hook 2 when the user wears it, thereby improving the wearing comfort of the user.

[0139] Optionally, as shown in Figures 16 and 18 , the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. When worn, the host module 1 is configured to be stacked on the user's ear along the thickness direction Y. The orthographic projection of the elastic buffer portion 26 on a reference plane perpendicular to the length direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane. That is, the orthographic projection of the elastic buffer portion 26 on a reference plane parallel to the width direction Z and the thickness direction Y partially overlaps with the orthographic projection of the free end 102 on the reference plane.

[0140] The elastic buffer portion 26 is arranged so that its orthographic projection on a reference plane perpendicular to the longitudinal direction X partially overlaps with the orthographic projection of the free end 102 on the reference plane, that is, the free end 102 and at least a portion of the elastic buffer portion 26 are relatively clamped on both sides of the ear, so that when clamping the user's ear, excessive pressure will not be applied while ensuring stability, thereby ensuring fit and improving comfort.

[0141] Furthermore, as shown in Figures 16 and 18 , the elastic buffer portion 26 is closer to the host module 1 than the connecting body 20. This increases the contact area between the elastic buffer portion 26 (which has a lower hardness) and the user's ear, allowing it to better conform to the ear structure when clamped, providing greater comfort. In some embodiments, the elastic buffer portion 26 can, for example, be closer to the host module 1 than the connecting body 20 in the radial direction of the ear hook 2, where the radial direction of the ear hook 2 is perpendicular to the extension direction of the ear hook 2.

[0142] Furthermore, as shown in Figures 16, 18, and 19, the elastic buffer portion 26 and the connecting body 20 are spliced ​​together. This allows the elastic buffer portion 26 (of lower hardness) to increase the contact area with the user's ear when the earhook 2 is attached to the user's ear, while reducing the contact area with the connecting body 20 (of higher hardness), thereby improving user comfort. In some embodiments, the elastic buffer portion 26 and the connecting body 20 can be spliced ​​together, for example, along the normal direction F of the outer contour of the earhook 2 and along the extension direction of the earhook 2, where the normal direction F of the outer contour of the earhook 2 is perpendicular to the outer contour of the earhook 2. Splicing the elastic buffer portion 26 and the connecting body 20 along the normal direction F of the outer contour of the earhook 2 facilitates positioning and installation, effectively reducing assembly difficulty.

[0143] Optionally, as shown in Figures 16, 18, and 19, the ear hook 2 has a first end 201 and a second end 202 disposed opposite each other. The first end 201 is connected to the main module 1, and the second end 202 is located on an elastic buffer portion 26. The elastic buffer portion 26 is circumferentially closed at the second end 202. The portion of the elastic buffer portion 26 that forms the second end 202 is located below the connecting body 20 in the direction from the first end 201 to the second end 202. The other portion of the elastic buffer portion 26 is located on the side of the connecting body 20 facing the main 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. The elastic buffer 26 is positioned partially on the side of the connecting body 20 facing the host module 1, allowing it to contact the user's ear more than the connecting body 20, thereby improving wearing comfort. The portion of the elastic buffer 26 forming the second end 202 is positioned below the connecting body 20 in the direction from the first end 201 to the second end 202 of the ear hook 2. This increases the contact area between the elastic buffer 26 and the ear, ensuring both wearing comfort and stability. The elastic buffer 26 is circumferentially closed at the second end 202, which reduces the ingress of foreign matter into the elastic buffer 26, preventing damage to the interior of the elastic buffer 26 and increasing its service life.

[0144] Furthermore, as shown in Figures 16 to 19, the first end 201 is connected to the host module 1, and the circumferential dimension R1 of the elastic buffer portion 26 gradually increases or increases in a step-like manner from the first end 201 to the second end 202. Because the first end 201 is connected to the host module 1, the first end 201 requires higher hardness to ensure the connection stability and reliability of the ear hook 2, and needs to provide sufficient support force to maintain the relative position between the ear hook 2 and the host module 1, so as to ensure that the user can wear and use the earphones 100 normally. Therefore, the elastic buffer portion 26 with lower hardness has a smaller circumferential dimension R1 near the first end 201, while the circumferential dimension R1 of the elastic buffer portion 26 gradually increases or increases in a step-like manner from the first end 201 to the second end 202, which can effectively improve the user's comfort.

[0145] Optionally, as shown in Figures 16 to 19, the connecting body 20 and the elastic buffer portion 26 are sequentially connected 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 ends connected to each other in the extension direction of the ear hook 2, thereby improving the aesthetics of the ear hook 2 and the stability of the connection while ensuring wearing comfort. In some embodiments, the circumferential dimension R2 of the connecting body 20 gradually decreases from the end connected to the elastic buffer portion 26 toward the first end 201. In some embodiments, the circumferential dimension R2 of the connecting body 20 gradually decreases and then gradually increases from the end connected to the elastic buffer portion 26 toward the first end 201. In other embodiments, the circumferential dimension R2 of the connecting body 20 at the end connected to the elastic buffer portion 26 is the maximum circumferential dimension of the connecting body 20.

[0146] Optionally, as shown in Figure 20, the connecting body 20 includes an elastic frame 21 and a covering member 22. The covering member 22 covers at least a portion of the elastic frame 21. An elastic buffer portion 26 is connected to the covering member 22. The elastic buffer portion 26 has a lower hardness than the covering member 22, which in turn has a lower hardness than the elastic frame 21. The elastic frame 21 provides primary support to maintain the relative shape of the ear hook 2, preventing deformation that could cause malfunction. The covering member 22 and the elastic buffer portion 26, with decreasing degrees of hardness, prevent direct contact between the elastic frame 21 and the user's ear, thereby improving wearing comfort. Optionally, a buffer cavity 220 can be provided in the ear hook 2, for example, in the covering member 22, the elastic buffer portion 26, or both, to increase its softness and deformability, thereby enhancing user comfort. For details, please refer to the description of the above embodiments.

[0147] In some embodiments, the covering part 22 covers a portion of the elastic skeleton 21, and the elastic buffer part 26 covers another portion of the elastic skeleton 21. The elastic skeleton 21 serves as a support and connection bridge for the ear hook 2, thereby improving the connection stability and reliability of the ear hook 2.

[0148] In some embodiments, the covering part 22 and the elastic buffer portion 26 are connected in sequence along the extension direction. The elastic buffer portion 26 does not cover the elastic skeleton 21, but is located downstream of the elastic skeleton 21 in the extension direction of the ear hook 2, so that the softness and deformable range of the elastic buffer portion 26 will not be affected, thereby maximizing the user's comfort and the applicability of the earphones 100.

[0149] In order to improve the wearing comfort of the ear hook 2, see the third example structure of the ear hook 2 below:

[0150] As shown in Figures 21 to 24, the ear hook 2 has a first end 201 and a second end 202 that are arranged opposite to each other, and the first end 201 is connected to the host module 1. The ear hook 2 is used to be hung on the user's ear 500. The ear hook 2 includes an elastic frame 21, a covering 22 and a fixing block 23. The elastic frame 21 extends along the extension direction from the first end 201 to the second end 202. The covering 22 includes a front covering section 221 and a rear covering section 222. The front covering section 221 and the rear covering section 222 are connected to each other in the extension direction. The fixing block 23 is arranged at an end of the elastic frame 21 away from the first end 201. The front covering section 221 covers the elastic frame 21 and the fixing block 23. The rear covering section 222 does not cover the elastic frame 21 and the fixing block 23, but is located downstream of the fixing block 23 in the extension direction. The extension length D2 of the rear covering section 222 along the extension direction is greater than or equal to the extension length D4 of the fixing block 23 along the extension direction. This arrangement can prevent the elastic frame 21 from piercing the covering member 22, making it easier to process and shape, and can effectively improve the processing accuracy.

[0151] The host module 1 is used to play sound. The ear hook 2 can be connected to the host module 1 through the first end 201, so that the host module 1 can be kept close to or in contact with the user's ear 500. The elastic skeleton 21 can support the covering 22 in the ear hook 2. The elastic skeleton 21 can be deformed to a certain extent. The covering 22 can cover the elastic skeleton 21 and can be deformed accordingly with the deformation of the elastic skeleton 21. In this way, the user can adjust the shape of the ear hook 2 by adjusting the shape of the elastic skeleton 21, so that the ear hook 2 can better adapt to the shape of the user's ear 500, improve the user's wearing comfort, and make the earphone 100 more stable to wear.

[0152] By providing a rear covering section 222 in addition to the front covering section 221 and setting the extension length D2 of the rear covering section 222 along the extension direction to be greater than or equal to the extension length D4 of the fixing block 23 along the extension direction, the rear covering section 222 is ensured to have sufficient length along the extension direction, thereby increasing the length of the ear hook 2 along the extension direction and improving the wearing comfort and stability of the earphone 100. By not covering the elastic frame 21 and the fixing block 23, the rear covering section 222 is not supported by the elastic frame 21 and the fixing block 23, which reduces the force exerted by the rear covering section 222 on the human ear and improves the wearing comfort of the user. Furthermore, by not providing the elastic frame 21 within the rear covering section 222, the material used for the elastic frame 21 can be reduced, thereby reducing costs.

[0153] Without the fixing block 23, there is a risk of the titanium wire piercing the covering member 22 (e.g., the rear covering member 222) of the elastic frame 21 when the rear covering member 222 is elastically bent relative to the front covering member 221. By providing the fixing block 23 at the end of the elastic frame 21 away from the first end 201, direct contact between the end of the elastic frame 21 away from the first end 201 and the rear covering member 222 when the rear covering member 222 is bent relative to the front covering member 221 can be reduced, thereby reducing the risk of the end of the elastic frame 21 away from the first end 201 piercing the covering member 22 (e.g., the rear covering member 222) and reducing the discomfort caused by the end of the elastic frame 21 away from the first end 201.

[0154] Furthermore, the radial dimension of the fixing block 23 perpendicular to the extension direction may be larger than the radial dimension of the elastic frame 21 at the end away from the first end 201 perpendicular to the extension direction. In other words, the circumferential dimension of the fixing block 23 may be larger than the circumferential dimension of the elastic frame 21.

[0155] Optionally, the covering member 22 is made of silicone, plastic or rubber.

[0156] 22 , in some embodiments, the extension length D2 of the rear covering section 222 along the extension direction is 10-25 mm.

[0157] Based on a large-scale model of the human auricle, since the front covering section 221 is closer to the rear hanging position of the ear tip (for suspending the ear hook 2), the further it extends toward the second end 202 of the ear hook 2, the greater the deviation between the ear hook 2 and the natural contour of the human ear may be. Therefore, the further back the ear hook 2 is, the greater the deformability required. By setting the extension length D2 of the rear covering section 222 along the extension direction to be greater than or equal to 10 mm, it is possible to ensure that the rear covering section 222 has sufficient length and deformability along the extension direction, effectively balancing the shape stability (fatigue resistance) and comfort (adaptability to a wider range of people) of the ear hook 2. Furthermore, this configuration of the rear covering section 222 ensures that the fixing block 23 will not puncture the covering 22 of the rear covering section 222.

[0158] By setting the extension length D2 of the rear covering section 222 along the extension direction to be less than or equal to 25 mm, the appearance and structure of the earphone 100 can be made simpler. Furthermore, the extension length D2 of the rear covering section 222 along the extension direction is 12-25 mm. For example, the extension length D2 of the rear covering section 222 along the extension direction is 12 mm, 15 mm, 18 mm, 20 mm, or 22 mm.

[0159] Optionally, an extension length D1 of the front covering section 221 along the extension direction is 35-80 mm.

[0160] By setting the extension length D1 of the front covering section 221 along the extension direction to be greater than or equal to 35 mm, the front covering section 221 can be ensured to have sufficient length along the extension direction, thereby improving the wearing stability of the earphone 100. By setting the extension length D1 of the front covering section 221 along the extension direction to be less than or equal to 70 mm, the force exerted by the front covering section 221 on the human ear can be reduced, improving the user's wearing comfort. At the same time, the material used in the elastic frame 21 can be reduced, thereby reducing costs. For example, the extension length D1 of the front covering section 221 along the extension direction is 40 mm, 45 mm, 48 mm, 50 mm, 55 mm, 60 mm, 65 mm, or 68 mm.

[0161] Optionally, the extension length D4 of the fixing block 23 along the extension direction is 6-15 mm. For example, the extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 may be 8 mm, 10 mm or 12 mm. With such a setting, on the one hand, the fixing block 23 can have a sufficient and reasonable length to cover the end of the elastic skeleton 21, making it more difficult for the elastic skeleton 21 to pierce the covering 22, thereby effectively reducing the probability of the end of the elastic skeleton 21 piercing the covering 22, and also improving the fixing effect between the elastic skeleton 21 and the fixing block 23. On the other hand, the above-mentioned size setting can achieve a better fixing effect between the covering 22 and the fixing block 23, so that the covering 22 better wraps the fixing block 23, thereby achieving a better fixing effect between the fixing block 23 and the elastic skeleton 21.

[0162] 22 , in some embodiments, the ratio of the extension length D1 of the front covering segment 221 along the extension direction to the extension length D2 of the rear covering segment 222 along the extension direction is greater than or equal to 2 and less than or equal to 4.5.

[0163] According to the large-scale model data of the human auricle, since the front covering section 221 is closer to the hanging position at the rear side of the ear tip (for hanging the ear hook 2), the further it extends toward the second end 202 of the ear hook 2, the greater the deviation between the ear hook 2 and the natural contour of the human ear may be. Therefore, the further back the ear hook 2 is, the greater the deformation ability it needs. Under the combination of the sizes of the front covering section 221 and the rear covering section 222, the front covering section 221 can serve as the deformation arm of the rear covering section 222 so that the rear covering section 222 obtains a higher deformation ability, which can well take into account the shape stability (fatigue resistance) and comfort (adaptability to a wider range of people) performance of the ear hook 2.

[0164] For example, the ratio of the extension length D1 of the front cladding section 221 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 2.2-2.5, 2.6-2.8, or 3.0-3.5. Furthermore, the ratio of the extension length D1 of the front cladding section 221 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 3.3-3.4.

[0165] 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 earhook 2 will have low wearing stability. 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 earhook 2 will be less comfortable to wear. 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 earhook 2 can achieve both good wearing stability and comfort.

[0166] 23 , in some embodiments, an end of the elastic skeleton 21 away from the first end 201 is inserted into the fixing block 23 .

[0167] By setting the end of the elastic skeleton 21 away from the first end 201 to be inserted into the fixing block 23, the fixing block 23 can cover the end of the elastic skeleton 21 away from the first end 201, which is conducive to the stable fixation of the fixing block 23 to the end of the elastic skeleton 21 away from the first end 201, thereby reducing the damage to the covering part 22 caused by the end of the elastic skeleton 21 away from the first end 201, and reducing the wearing discomfort caused by the end of the elastic skeleton 21 away from the first end 201.

[0168] 23 , in some embodiments, the connection between the end surface of the fixing block 23 facing the rear cladding section 222 and the peripheral side surface of the fixing block 23 is chamfered or configured as a curved surface. For example, the connection between the end surface of the fixing block 23 facing the rear cladding section 222 and the peripheral side surface of the fixing block 23 forms a curved transition.

[0169] The front covering section 221 provides stronger support for the user's ear 500, while the rear covering section 222 provides weaker support for the user's ear 500. By chamfering or providing a curved surface at the junction between the end surface of the fixing block 23 facing the rear covering section 222 and the peripheral side surface of the fixing block 23, the support for the user's ear 500 at the junction of the rear covering section 222 and the front covering section 221 can be more smoothly transitioned, thereby improving the user's wearing comfort.

[0170] 23 and 25 , in some embodiments, the front covering segment 221 and / or the rear covering segment 222 is provided with a first positioning hole 223 , and the fixing block 23 can be exposed through the first positioning hole 223 .

[0171] During the production process of the ear hook 2, the first positioning hole 223 can avoid the external positioning device, thereby allowing the external positioning device to position the fixing block 23 through the first positioning hole 223, thereby reducing the deformation of the elastic skeleton 21 during the production process of the ear hook 2, making the shape and position dimensions between the various components of the ear hook 2 more precise, and improving the quality yield of the ear hook 2.

[0172] The first positioning holes 223 defined in the front covering section 221 allow external positioning devices to act on the peripheral side surface of the fixing block 23 or the end surface of the fixing block 23 facing away from the rear covering section 222. The first positioning holes 223 defined in the rear covering section 222 allow external positioning devices to act on the end surface of the fixing block 23 facing the rear covering section 222. For example, if both the front covering section 221 and the rear covering section 222 are provided with first positioning holes 223, external positioning devices can act on different positions of the fixing block 23, thereby improving the fixing effect of the positioning block.

[0173] Furthermore, a pair of first positioning holes 223 is provided in the front covering section 221 and / or the rear covering section 222. The two pairs of first positioning holes 223 are arranged opposite each other, so that the opposite sides of the fixing block 23 are exposed through the first positioning holes 223. This arrangement facilitates the positioning of the fixing block 23 and improves the fixing effect of the fixing block 23.

[0174] 23 and 25 , in some embodiments, the first positioning hole 223 is opened on the peripheral side of the front covering section 221 and / or the rear covering section 222 , and a groove 224 is also opened on the peripheral side of the front covering section 221 and / or the rear covering section 222 , and the first positioning hole 223 is opened at the bottom of the groove 224 .

[0175] On the one hand, the groove 224 can reduce the size of the front covering section 221 and / or the rear covering section 222, providing deformation space for the front covering section 221 and / or the rear covering section 222. This makes it easier for the front covering section 221 and / or the rear covering section 222 to deform when subjected to force, making it easier for the user to wear the headset and improving wearing comfort. On the other hand, the groove 224 facilitates the user's tactile identification of the headset 100, facilitating the user's tactile sensing of the headset's posture and position in space, thereby facilitating the user's correct wearing and use of the headset 100 without visual assistance.

[0176] 23 and 25 , in some embodiments, the first positioning hole 223 is located at one end of the groove 224 , and the other end of the groove 224 extends toward the second end 202 .

[0177] This arrangement facilitates the user to simultaneously sense the second end 202 and the groove 224 through tactile sensation, making it easier for the user to sense the posture and position of the earphone 100 in space through tactile sensation. At the same time, the groove 224 is more located in the rear covering section 222, which facilitates the deformation of the rear covering section 222.

[0178] 21 , 23 , and 1 , in some embodiments, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. The host module 1 is configured to be stacked on the ear portion 500 along the thickness direction Y when worn. The first positioning hole 223 extends along the thickness direction Y.

[0179] The covering member 22 can be coated onto the elastic frame 21 by injection molding, and the first positioning holes 223 are also formed in the covering member 22 by injection molding. By configuring the first positioning holes 223 to extend along the thickness direction Y, during the injection molding process, the mold opening direction is consistent with the direction in which the mold is separated from the first positioning holes 223, thereby facilitating demolding of the covering member 22.

[0180] Furthermore, the first positioning hole 223 is provided on the side of the ear hook 2 facing the host module 1 when the earphone is worn. This arrangement is conducive to the ear 500 shielding the first positioning hole 223 when the earphone is worn, thereby improving the appearance of the earphone 100.

[0181] 23 , optionally, the fixing block 23 is provided with a second positioning hole 231 , and the first positioning hole 223 and the second positioning hole 231 are arranged opposite to each other and are in communication.

[0182] The second positioning hole 231 is provided to facilitate an external positioning device to position the fixing block 23 , thereby improving the fixing effect. For example, an external positioning device can be inserted into the second positioning hole 231 to position the fixing block 23 .

[0183] Furthermore, the second positioning hole 231 is a blind hole, which can facilitate demoulding during the injection molding process on one hand, and can prevent the second positioning hole 231 from penetrating the fixing block 23 on the other hand, so that the fixing block 23 can maintain a high strength.

[0184] Furthermore, the second positioning holes 231 are provided in pairs. The two second positioning holes 231 are arranged opposite each other, so that both opposite sides of the fixing block 23 can be fixed through the second positioning holes 231. This arrangement facilitates the positioning of the fixing block 23 and improves the fixing effect of the fixing block 23.

[0185] 22 , in some embodiments, the earphone 100 further includes a functional component 26a, which is detachably connected to the first positioning hole 223. This configuration can improve the aesthetics and functionality of the earphone 100. For example, a user may wear an earphone 200 on each of their left and right ears. The functional component 26a can be configured to detachably connect the two earphones 100 together (e.g., by snapping, bonding, threading, magnetic connection, or connection via an additional fastener), reducing the risk of losing the earphone 100.

[0186] 22 , further, the functional component 26a is a lanyard that can be used to connect two earphones 100. Of course, the functional component 26a can also be an arc-shaped metal component, and two functional components 26a can be spliced ​​together to form a larger arc-shaped structure.

[0187] In some embodiments, the hardness of the fixing block 23 is greater than the hardness of the covering member 22. By setting the fixing block 23 to have a greater hardness, the protective effect of the fixing block 23 on the covering member 22 can be improved. By setting the covering member 22 to have a lower hardness, the wearing comfort of the user can be improved.

[0188] Optionally, the covering member 22 is made of relatively soft plastic, silicone or rubber, and the fixing block 23 is made of relatively hard plastic or metal.

[0189] 22 and 23 , optionally, the front covering section 221 and the rear covering section 222 are integrally formed, and the front covering section 221 is integrally formed around the elastic frame 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.

[0190] Such an arrangement can ensure that the covering member 22 has a good and uniform covering effect, while at the same time ensuring that the front covering section 221 and the rear covering section 222 can be stably connected.

[0191] With reference to Figure 22 , in some embodiments, the host module 1 includes a connection end 103 connected to the first end 201 of the ear hook 2 and a free end 102 distal to the connection end 103. At least a portion of the rear covering section 222 is disposed opposite the free end 102. This arrangement ensures that when the earphone 100 is worn, at least a portion of the rear covering section 222 and the free end 102 are located on either side of the same position on the ear 500. Furthermore, at least a portion of the rear covering section 222 and the free end 102 exert equal force on both sides of the same position on the ear 500, thereby improving wearing comfort.

[0192] With reference to Figure 22 , in some embodiments, the host module 1 includes a connection end 103 connected to the first end 201 of the ear hook 2 and a free end 102 distal to the connection end 103, with the fixing member positioned opposite the free end 102. This arrangement allows the fixing member and the free end 102 to be located on opposite sides of the same position on the ear 500 when the earphone 100 is worn. This further allows the host module 1 and the front covering section 221 to exert equal force on both sides of the ear 500, thereby improving wearing stability.

[0193] In conjunction with FIG. 22 and FIG. 1 , in some embodiments, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to one another. When worn, the host module 1 is configured to be stacked on the ear portion 500 along the thickness direction Y. A dimension T1 of the rear covering section 222 along the width direction Z is greater than a dimension T2 of the host module 1 along the width direction Z.

[0194] Such a configuration can ensure that the rear covering section 222 has a sufficient length along the width direction Z, thereby improving the wearing comfort and stability of the earphone 100.

[0195] 21 and 22 , in some embodiments, the host module 1 has an inner side surface IS facing the ear 500 along the thickness direction Y and an outer side surface OS facing away from the ear 500 when worn, as well as an upper side surface US and a lower side surface LS2 connecting the inner side surface IS and the outer side surface OS. The upper side surface US and the lower side surface 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 surface LS2 in the width direction Z.

[0196] Such a configuration can ensure that the rear covering section 222 has a sufficient length along the width direction Z, thereby improving the wearing comfort of the earphone 100. At the same time, it is beneficial for the ear hook 2 to have a sufficient length along the width direction Z, thereby improving the wearing stability of the earphone 100.

[0197] With reference to Figure 22 , in some embodiments, at least a portion of the fixing block 23 is located between the extension plane of the upper side surface US and the extension plane of the lower side surface LS2, and an extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 is 6-15 mm. For example, a portion of the fixing block 23 is located between the extension plane of the upper side surface US and the extension plane of the lower side surface LS2, and another portion of the fixing block 23 is located on the side of the extension plane of the upper side surface US closer to the first end 201. The extension length D4 of the fixing block 23 along the extension direction of the ear hook 2 can be 8 mm, 10 mm, or 12 mm.

[0198] This arrangement allows at least a portion of the fixing block 23 and the main module 1 to be located on either side of the same location on the ear 500 when the earphone 100 is worn. Furthermore, at least a portion of the rear fixing block 23 and the main module 1 exert equal force on both sides of the same location on the ear 500, thereby improving wearing stability and support. Furthermore, in conjunction with the rear covering segment 222, this effectively enhances wearing comfort. Furthermore, the fixing block 23 at one end of the elastic frame 21 can extend between the plane extending from the upper side US and the plane extending from the lower side LS2 and be configured to the aforementioned dimensions. This, on the one hand, allows the elastic frame 21 and fixing block 23 to have a larger overall force arm relative to the first end 201 of the ear hook 2, thereby enabling deformation in a more force-saving manner when worn. Alternatively, this reduces pressure on the user's ear while maintaining the same clamping effect, improving wearing comfort. Furthermore, it provides better support, allowing the rear covering segment 222 to fit more closely against the ear, further enhancing wearing comfort through its cushioning properties.

[0199] 26 , in some embodiments, the rear covering section 222 defines a buffer cavity 220 , and at least a portion of the buffer cavity 220 is located at a portion of the rear covering section 222 that is opposite to the free end 102 .

[0200] When the earphone 100 is worn, at least a portion of the buffer cavity 220 and the free end 102 are located on either side of the same location on the ear 500. This allows at least a portion of the rear covering section 222 and the free end 102 to exert equal force on both sides of the force arm at the same location on the ear 500. The buffer cavity 220 reduces the size of the rear covering section 222, providing space for deformation. This allows the rear covering section 222 to more easily deform to conform to the shape of the ear 500 when subjected to force, reducing the force on the ear 500 between the free end 102 and the rear covering section 222, making it easier for the user to wear the earphone and improving wearing comfort.

[0201] 1 and 26 , in some embodiments, the free end 102 is configured to extend into the concha cavity 502 of the ear 500 when in a worn state, and the free end 102 and the rear covering section 222 are configured to jointly clamp the ear 500 area from the front and rear sides of the area of ​​the ear 500 corresponding to the concha cavity 502 when in a worn state, and the buffer cavity 220 is located in the portion of the rear covering section 222 used to clamp the ear 500 area.

[0202] By configuring the free end 102 to extend into the concha cavity 502 of the ear 500 when worn, the ear facilitates receiving sound emitted by the earphone 100. When the earphone 100 is worn, at least a portion of the buffer cavity 220 and the free end 102 are located on the front and rear sides of the region of the ear 500 corresponding to the concha cavity 502, respectively. This allows the portion of the rear covering section 222 that grips the ear 500 region and the free end 102 to exert equal force on the front and rear sides of the region of the ear 500 corresponding to the concha cavity 502. The buffer cavity 220 reduces the size of the rear covering section 222, providing room for deformation. This allows the rear covering section 222 to more easily deform to conform to the shape of the ear 500 when subjected to force, reducing the force acting between the free end 102 and the rear covering section 222 on the region of the ear 500 corresponding to the concha cavity 502. This facilitates wearing and enhances wearing comfort.

[0203] With reference to FIG22 , in some embodiments, the buffer cavity 220 is configured as an elongated 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 cladding section 222 along the extension direction is greater than or equal to one-half and less than or equal to four-fifths. For example, the ratio of the extension length T3 of the buffer cavity 220 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is in the range of 0.6-0.7. For example, the ratio of the extension length T3 of the buffer cavity 220 along the extension direction to the extension length D2 of the rear cladding section 222 along the extension direction is one-third.

[0204] Such a configuration can not only provide the buffer cavity 220 with sufficient deformation space for the rear covering section 222, but also maintain good support performance for the rear covering section 222. The buffer cavity 220 is provided to facilitate tactile recognition when taking off or wearing the device.

[0205] In conjunction with Figures 24 and 25 , in some embodiments, the ear hook 2 further includes a connector 24, which is fixedly disposed at an end of the elastic frame 21 near the first end 201 and is plugged and fixed to the host module 1. The extension length T4 of the connector 24 along the extension direction is greater than the extension length D4 of the fixing block 23 along the extension direction.

[0206] The provision of the connector 24 facilitates assembly of the earhook 2 and the host module 1. For example, the connector 24 enables a snap-fit ​​connection between the earhook 2 and the host module 1. By setting the extension length T4 of the connector 24 along the extension direction to be greater than the extension length D4 of the fixing block 23 along the extension direction, the connection stability between the earhook 2 and the host module 1 is improved. Furthermore, this arrangement allows for greater shape precision of the outer periphery of the connector 24 near the end of the host module 1 during injection molding of the earhook 2, thereby enhancing product consistency across the entire earhook 2.

[0207] With reference to Figures 22, 24, and 25, in some embodiments, the elastic frame 21 is inserted into the connector 24, which has a third positioning hole 241 defined around its periphery. The host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. When worn, the host module 1 is configured to be stacked on the ear portion 500 along the thickness direction Y. The third positioning hole 241 extends along the thickness direction Y.

[0208] By setting the third positioning hole 241, during the production process of the ear hook 2, it is convenient for an external positioning device to connect to the plug-in 24 for positioning, thereby reducing the deformation of the elastic skeleton 21 during the production process of the ear hook 2, making the shape and position dimensions between the various components of the ear hook 2 more accurate, and improving the quality yield of the ear hook 2.

[0209] The connector 24 can be formed by injection molding, and the third positioning hole 241 is also formed in the connector 24. By arranging the third positioning hole 241 to extend along the thickness direction Y, during the injection molding process, the mold opening direction is consistent with the direction in which the mold is separated from the third positioning hole 241, thereby facilitating demolding of the connector 24.

[0210] Furthermore, the third positioning hole 241 is a blind hole, which can facilitate demoulding during the injection molding process on one hand, and can prevent the third positioning hole 241 from penetrating the fixing block 23 on the other hand, so that the fixing block 23 can maintain a high strength.

[0211] In some embodiments, as shown in Figures 14 and 15a, the host module 1 has a length direction X, a width direction Z, and a thickness direction Y that are perpendicular to each other. The host module 1 is used to be stacked on the ear along the thickness direction Y when worn. The extension direction of the end of the elastic skeleton 21 close to the first end 201 has a first angle Q1 with the length direction X toward the ear hook 2, and the extension direction of the connector 24 has a second angle Q2 with the length direction X toward the ear hook 2. The first angle Q1 is smaller than the second angle Q2.

[0212] Whether it is the headset 100 or other electronic devices 300 such as computers, mobile phones, tablet computers, etc., they are all provided with a charging interface, a data transmission interface, or both. The following is an exemplary description of exemplary content about the interface of the electronic device 300.

[0213] As shown in FIG27 , an electronic device 300 may include a battery 14 and an interface circuit 310 . The interface circuit 310 is coupled to the battery 14 so that an external charging device can charge the battery 14 via the interface circuit 310 . The electronic device 300 may be a mobile phone, a computer, a headset, or the like. The external charging device may be a power bank, a charging station, or other device that can output power to the electronic device 300 via the interface circuit 310 .

[0214] In some embodiments, as shown in Figures 7, 8 and 27, the electronic device 300 may include a charging box 900 and an earphone 100, the charging box 900 accommodates the earphone 100 and is used to charge the earphone 100, and the interface circuit 310 may be arranged in the charging box 900, so that an external charging device can charge the charging box 900 through the interface circuit 310, so that the charging box 900 can obtain electrical energy from the external charging device, and the charging box 900 can charge the earphone 100 when it is accommodated in the charging box 900.

[0215] For example, as shown in FIG28 , 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). The identification pin A5 (B5) may be used to allow the external charging device to detect the coupling status 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) may be used to continuously transmit the coupling status to the external charging device, allowing the external charging device to monitor the coupling status between the interface circuit 310 and the external charging device in real time and to respond promptly based on the detected coupling status, thereby minimizing safety incidents. In some embodiments, the external charging device may be configured to intermittently detect the coupling status between the interface circuit 310 and the external charging device. For example, the external charging device may detect the coupling status every 5 or 10 seconds, thereby saving energy consumption for the external charging device and the electronic device 300.

[0216] The preset thermistor 312 can be configured to change the coupling state of the interface circuit 310 detected by the external charging device in response to changes in the temperature of the power receiving interface 311. As shown in Figure 28, the preset thermistor 312 can be coupled to identification pin A5 (B5). After detecting changes in the temperature of the power receiving interface 311, the preset thermistor 312 further changes the coupling state between the interface circuit 310 and the external charging device based on the temperature of the power receiving interface 311. The coupling state is then transmitted to the external charging device via identification pin A5 (B5). By providing a preset thermistor 312 and an identification pin A5 (B5) connected to the preset thermistor 312 in the interface circuit 310, when the electronic device 300 is connected to an external charging device for charging through the interface circuit 310, the external charging device can promptly monitor the temperature of the power receiving interface 311, thereby being able to grasp the coupling status of the interface circuit 310 and the external charging device in real time, so as to be able to more sensitively make the next step response based on the detected coupling status, thereby timely protecting the electronic device 300 and minimizing safety accidents.

[0217] In some embodiments, the power receiving interface 311 may be a Type-C interface, and the identification pin A5 (B5) may be a CC (Configuration Channel) pin. Specifically, the Type-C interface is a USB interface standard with a smaller size than both Type-A and Type-B. It is an interface type that can be used for both PCs (master devices) and external devices (slave devices, such as mobile phones, headphones 100, or charging boxes 900). The CC pin is mainly used to identify the type of device plugged into the power receiving interface 311 and communicate, and is also used to confirm the data transmission direction and the forward and reverse insertion direction. In some embodiments, setting the CC pin to be connected to a preset thermistor 312 allows the external charging device to directly receive data information related to the coupling status through the CC pin, improving the efficiency of the external charging device in determining the coupling status between the interface circuit 310 and the external charging device, and also saving internal components and space of the interface circuit 310, thereby improving the space utilization of the interface circuit 310.

[0218] Of course, in other implementations, the power receiving interface 311 may be other interfaces such as Type-A or Type-B, and the identification pin A5 (B5) may be other pins such as the VBUS pin.

[0219] In some embodiments, the resistance of the preset thermistor 312 can change with the temperature of the power receiving interface 311, allowing the external charging device to detect the coupling status via identification pin A5 (B5) based on the resistance of the preset thermistor 312. The preset thermistor 312 can be specifically a sensor resistor, typically characterized by its resistance changing with temperature, i.e., its resistance value varies at different temperatures. Therefore, the resistance of the preset thermistor 312 can directly reflect the temperature change of the power receiving interface 311. By configuring the external charging device to directly detect the coupling status between the external charging device and the interface circuit 310 based on the resistance of the preset thermistor 312, the coupling status determined by the external charging device can be more accurate.

[0220] In some embodiments, identification pin A5 (B5) can be connected to ground via a pre-set thermistor 312. Specifically, the pre-set thermistor 312 is positioned between identification pin A5 (B5) and ground. When the external charging device is connected to the power receiving interface 311, if the temperature of the pre-set thermistor 312 is too high, resulting in a high resistance value, the pre-set thermistor 312 can block the connection between identification pin A5 (B5) and ground. The resistance value of the pre-set thermistor 312 may even approach infinity, disconnecting the external charging device from ground. This allows the external charging device to determine the coupling status with the interface circuit 310 by connecting to ground. Furthermore, the pre-set thermistor 312 is directly connected to identification pin A5 (B5), allowing it to directly detect and reflect temperature changes in the power receiving interface 311 without being affected by other circuit components. This also allows for more accurate communication of the coupling status between the interface circuit 310 and the external charging device to the external charging device.

[0221] In some embodiments, the preset thermistor 312 can be set so that when its resistance is within a predetermined resistance range, the coupling state detected by the external charging device is normal, and when its resistance is not within the predetermined resistance range, the coupling state detected by the external charging device is abnormal.

[0222] The predetermined resistance range may be set with reference to a temperature tolerance threshold of the power receiving interface 311 during normal operation, so that the predetermined resistance range can indicate that the operating temperature of the power receiving interface 311 is normal when coupled to an external charging device.

[0223] When the resistance of the preset thermistor 312 is within the predetermined resistance range, it indicates that the temperature of the power receiving interface 311 is at a normal temperature. At this normal temperature, the power receiving interface 311 can maintain normal functions such as power supply and communication with the external charging device, which further indicates that the external charging device has detected that the coupling status between the power receiving interface 311 and the external charging device is normal.

[0224] When the resistance value of the preset thermistor 312 is outside the preset resistance range, it indicates that the temperature of the power receiving interface 311 detected by the preset thermistor 312 is too high. The power receiving interface 311 at such a high temperature may affect normal communication or power supply with the external charging device. Therefore, the external charging device detects that the coupling state is abnormal.

[0225] For example, the preset resistance range can be 4.9KΩ-5.3KΩ. When the resistance of the preset thermistor 312 is within 4.9KΩ-5.2KΩ, the coupling state detected by the external charging device is normal. When the resistance of the preset thermistor 312 is less than 4.9KΩ or greater than 5.2KΩ, the coupling state detected by the external charging device is abnormal. Of course, in other embodiments, the preset resistance range can also be other values. For example, if a different type of thermistor is used, the preset resistance range can also be other resistance ranges corresponding to the thermistor. For example, the preset resistance range can also be 4.7KΩ-5.4KΩ, 5KΩ-5.5KΩ, and other resistance ranges. This application will not specifically list them one by one here.

[0226] By setting a predetermined resistance range for the preset thermistor 312 and detecting whether the real-time resistance value of the preset thermistor 312 is within the predetermined resistance range to reflect the coupling status between the power receiving interface 311 and the external charging device, the external charging device can obtain a more accurate detection result, thereby improving the safety of the interface circuit 310.

[0227] In some embodiments, the nominal resistance of the preset thermistor 312 can be 4.8KΩ to 5.4KΩ. This configuration allows the preset thermistor 312 to detect a wider operating temperature range, making the preset thermistor 312 more sensitive, thereby enabling the external charging device to more accurately detect the power receiving interface 311. In other embodiments, depending on the model of the thermistor, the nominal resistance of the preset thermistor 312 can also be other resistances corresponding to the 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, which are not specifically limited in this application.

[0228] In some embodiments, the preset thermistor 312 can be set to have a resistance value within a predetermined resistance range when the temperature of the power receiving interface 311 is within a predetermined temperature range, and to have a resistance value outside the predetermined resistance range when the temperature of the power receiving interface 311 is not within the predetermined temperature range.

[0229] Specifically, the predetermined temperature range can be referenced to the normal temperature of the power receiving interface 311 when coupled to an external charging device and capable of 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 power receiving interface 311 is within the predetermined temperature range, the resistance of the preset thermistor 312 is within the predetermined resistance range, and the external charging device detects that the coupling status is normal. If the temperature of the power receiving interface 311 is not within the predetermined temperature range, the resistance of the preset thermistor 312 is not within the predetermined resistance range, and the external charging device detects that the coupling status is abnormal.

[0230] In some embodiments, if the operating temperature of the power receiving interface 311 is within the range of 0°C-45°C, the power receiving interface 311 can normally provide power and communicate with the external charging device. The predetermined temperature range can be set to 0°C-45°C, and the corresponding predetermined resistance range can be set to 4.9KΩ-5.3KΩ. When the external charging device detects a normal coupling state, this indicates that the temperature of the power receiving interface 311 is within the predetermined temperature range of 0°C-45°C, the resistance of the preset thermistor 312 is within the predetermined temperature range of 4.9KΩ-5.3KΩ, and the power receiving interface 311 is operating normally. However, when the temperature of the power receiving interface 311 is greater than 45°C, the power receiving interface 311 is no longer suitable for receiving power or communicating with the external charging device. The resistance of the preset thermistor 312 is outside the predetermined resistance range, for example, less than 4.9KΩ or greater than 5.3KΩ, and the external charging device detects an abnormal coupling state. In some embodiments, if the maximum temperature that the power receiving interface 311 can withstand is 80°C, the predetermined temperature range can be set to 0°C to 75°C. At this time, if the temperature of the power receiving interface 311 exceeds the predetermined temperature range, the resistance of the preset thermistor 312 will approach zero or infinity, and the coupling state detected by the external charging device is abnormal.

[0231] Of course, in other implementations, the predetermined temperature range may also be other values, and the predetermined resistance range corresponding to the predetermined temperature range may also be other values, which are not listed in detail one by one in this application.

[0232] In the aforementioned embodiment, the predetermined resistance range is set based on the normal operating temperature range of the power receiving interface 311, and the coupling status between the power receiving interface 311 and the external charging device is determined based on this range. This allows the external charging device to promptly monitor the temperature of the power receiving interface 311, promptly identify any abnormal conditions in the power receiving interface 311, and promptly respond, thereby improving the operating safety of the interface circuit 310.

[0233] In some embodiments, as shown in FIG29 , the power receiving interface 311 may include a power supply pin A4 (B4), which may be used to receive a charging voltage output by an external charging device when the interface circuit 310 is coupled to the external charging device. The external charging device stops outputting the charging voltage to the power supply pin A4 (B4) upon detecting an abnormal coupling state.

[0234] In some embodiments, the power supply pin A4 (B4) can be a VBUS pin, which can be connected to the pin of the output voltage in the external charging when the external charging device is coupled to the electrical 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).

[0235] Specifically, when the external charging device detects an abnormal coupling state, it can be indicated that the temperature of the power receiving interface 311 exceeds the predetermined temperature range, and the temperature of the power receiving interface 311 is too hot or too cold. At this time, the external charging device stops outputting the charging voltage to the power supply pin A4 (B4), thereby protecting the power receiving interface 311 and minimizing safety accidents.

[0236] In some embodiments, as shown in FIG. 29 , the number of identification pins A5 ( B5 ) may be two, and the number of preset thermistors 312 may also be two, with the two identification pins A5 ( B5 ) and the two preset thermistors 312 corresponding one to one.

[0237] Providing two identification pins A5 (B5) can enhance the power supply communication function between the power receiving interface 311 and the external charging device. Providing two preset thermistors 312 can perform dual detection of the temperature of the power receiving interface 311, thereby making the external charging device more accurate in detecting the temperature of the power receiving interface 311.

[0238] In some embodiments, as shown in FIG. 29 , the number of the power supply pins A4 ( B4 ) may also be two, namely a first power supply pin A4 ( B4 ) and a second power supply pin A4 ( B4 ).

[0239] In some embodiments, as shown in FIG. 29 , the power receiving interface 311 may further include a ground pin, a receiving pin, a transmitting pin, any plug pin, and an auxiliary pin.

[0240] The ground pin is used to connect to a ground line. For example, the ground pin may be a GND pin. Optionally, the number of ground pins may be four, and the four ground pins are respectively a first ground pin A1, a second ground pin A12, a third ground pin B1, and a fourth ground pin B12.

[0241] The transmit pins may include a positive transmit pin and a negative transmit pin. The number of both positive and negative transmit pins can be set to two. The positive transmit pins include a first positive transmit pin A2 and a second positive transmit pin B2, and the negative transmit pins include a first negative transmit pin A3 and a second negative transmit pin B3. The transmit pins are used for high-speed data transmission. After an external device is plugged into the coupling receiving electrical interface 311, the transmit pins are used to transmit data to the external device at high speed.

[0242] The receiving pins may include a positive receiving pin and a negative receiving pin. The number of both the positive receiving pins and the negative receiving pins may be 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 an external device is plugged into the coupling receiving electrical interface 311, the receiving pins are used to receive data transmitted by the external device at high speed.

[0243] The random pins may also include a positive random pin and a negative random pin. For example, the positive random pin is the D+ pin, and the negative random pin is the D- pin. Both the positive random pin and the negative random pin may be provided in pairs. The positive random pins include a first positive random pin A6 and a second positive random pin B6, and the negative random pins include a first negative random pin A7 and a second negative random pin B7. The random pins are used to transmit two sets of USB 2.0 signals. The positive random pins and the negative random pins are cross-connected, so that data is connected when an external device is connected in either direction.

[0244] The auxiliary pin is used to assist the power receiving interface 311 in transmitting auxiliary signals to an external charging device in certain special modes. The auxiliary pin can be an SBU pin. There can be two auxiliary pins, namely a first auxiliary pin A8 and a second auxiliary pin B8.

[0245] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the scope of patent protection of the present application.
