[0041] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0042] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0043] Combination Figure 1 The ear 100 of the user may include an external auditory canal 101, a cavum conchae 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid 106, an auricle 107, an antitragus 108 and other physiological parts. Among them, although the external auditory canal 101 has a certain depth and extends to the eardrum, for the convenience of description, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 102, the hymena conchae 103, the triangular fossa 104 and other physiological parts have a certain volume and depth; and the concha cavity 102 is directly connected to the external auditory canal 101, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 102.

[0044] Furthermore, different users may have individual differences, resulting in different shapes, sizes, and other dimensional differences in the ears. For ease of description, and to 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, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, to present the scenario of most users wearing the headphones 10. Taking GRAS KEMAR as an example, the ear simulator can be any one of GRAS 45AC, GRAS 45BC, GRAS 45CC, or GRAS 43AG, etc.; taking HEAD Acoustics as an example, the ear simulator can be any one of HMS II.3, HMS II.3LN, or HMS II.3LN HEC, etc. Therefore, in the present application, descriptions such as "the user wears the earphone 10", "the earphone 10 is in a wearing state", and "in a wearing state" may refer to the earphone 10 described in the present application being worn on the ear of the aforementioned simulator. Of course, precisely because of individual differences among different users, there may be certain differences between the earphone 10 worn by different users and the earphone 10 worn on the ear of the aforementioned simulator, but such differences should be tolerated.

[0045] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the up-down direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear". The former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. They are both for the user's ear. Among them, when observing the ear of the above simulator along the direction of the human coronal axis, it can be obtained Figure 1 Schematic diagram of the front profile of the ear shown.

[0046] As an example, in combination Figures 2 to 4 The earphone 10 may include a movement module 11 and an ear hook portion 12 connected to the movement module 11, the movement module 11 is located on the front side of the ear in the wearing state, and at least part of the ear hook portion 12 is located on the back side of the ear in the wearing state, so that the earphone 10 is hung on the ear in the wearing state. The movement module 11 may have a connecting end CE connected to the ear hook portion 12 and a free end FE not connected to the ear hook portion 12. Further, the movement module 11 may be configured not to block the external auditory canal in the wearing state, so that the earphone 10 acts as an "open earphone". Due to individual differences among different users, when the earphone 10 is worn by different users, the movement module 11 may partially block the external auditory canal, but the external auditory canal is still not blocked.

[0047] Optionally, in some embodiments, the movement module 11 includes a movement housing (in some embodiments of the present application, the movement housing is also referred to as a housing assembly 110), a speaker 111 and a main control circuit board 112, wherein the speaker 111 and the main control circuit board 112 are arranged in a stacked manner in the movement housing, and such an arrangement can effectively improve the space utilization of the earphone 10. Among them, the speaker 111 is a component that can convert an electrical signal into a corresponding sound signal under the control of the main control circuit board 112. The main control circuit board 112 is an integrated circuit module of the earphone 10, on which a variety of control circuits for controlling the speaker 111, Bluetooth, microphone and other earphone 10 components are arranged, for example, a main control circuit. Among them, in this embodiment, the speaker 111 is an air conduction speaker 111, and in other embodiments, the speaker 111 can also be set as a bone conduction speaker 111.

[0048] Optionally, in some embodiments, the housing assembly 110 includes a first housing 1101 and a second housing 1102 that cooperate with each other. Such a configuration can effectively improve the assembly efficiency of the earphone 10 .

[0049] Alternatively, if Figures 5 to 8 As shown, in some embodiments, the ear hook portion 12 includes an elastic connector 122 and a accommodating shell 124, one end of the elastic connector 122 is connected to the movement module 11, and the other end is connected to the accommodating shell 124. In this configuration, the elastic connector 122 can provide elastic force for the movement module 11 located on the front side of the ear and the accommodating shell 124 located on the back side of the ear, so that the elastic connector 122 clamps the front and back sides of the ear through the accommodating shell 124 and the movement module 11, thereby effectively improving the wearing stability of the earphone 10.

[0050] Alternatively, if Figures 5 to 8As shown, in some embodiments, the ear hook portion 12 also includes an elastic covering body 121 covering the elastic connecting member 122 and the periphery of the accommodating shell 124, wherein the elastic covering body 121 is an elastic and flexible member. Such a configuration enables the ear hook portion 12 to abut against the ear through the elastic covering body 121, thereby effectively improving the wearing comfort of the ear hook portion 12, and further effectively improving the wearing comfort of the earphone 10.

[0051] Alternatively, if Figures 5 to 8 As shown, in some embodiments, the housing 124 is formed with a housing 1243, and the housing 1243 is used to accommodate at least part of the internal structural parts of the earphone 10, such as a battery. Further, in some embodiments, the elastic coating body 121 includes a first coating section 1211 and a second coating section 1212, and at least part of the second coating section 1212 is coated on at least part of the periphery of the housing 124 away from the elastic connector 122 by a sleeve method, so as to reduce the risk of damage to the internal structural parts when at least part of the second coating section 1212 is assembled to the part of the housing 124 by other assembly processes, further improve the working stability of the earphone 10, and effectively reduce the assembly complexity of the ear hook part 12. Further, in some embodiments, at least part of the first coating section 1211 is coated on the periphery of the elastic connector 122 by a molding method, which can effectively improve the stability of the ear hook part 12. For example, in some embodiments, at least a portion of the first covering section 1211 may be covered around the periphery of the elastic connector 122 by injection molding.

[0052] Specifically, in this embodiment, the first covering section 1211 and the second covering section 1212 are integrated structures, which can effectively reduce the assembly complexity of the ear hook portion 12. In other embodiments, the first covering section 1211 and the second covering section 1212 can also be split structures.

[0053] Alternatively, if Figure 5As shown, in some embodiments, the accommodating shell 124 includes a first shell 1241 and a second shell 123, one end of the second shell 123 is connected to the other end of the elastic connector 122 (that is, the free end ZY of the elastic connector 122), and the other end is connected to the first shell 1241, so as to cooperate with the first shell 1241 to form a accommodating chamber 1243. An opening 1213 is provided at the free end ZY of the second covering section 1212 away from the elastic connector 122. Specifically, during assembly, the second covering section 1212 can be pulled up from one end of the opening 1213 of the second covering section 1212 to expose the connection between the first shell 1241 and the second shell 123, so that the first shell 1241 can be easily matched and connected with the second shell 123. After the connection is completed, the second covering section 1212 is rolled down and sleeved on at least part of the periphery of the first shell 1241. This arrangement allows the second covering section 1212 to be sleeved on the periphery of the first shell 1241, thereby effectively improving the working stability of the earphone 10 and effectively reducing the assembly complexity of the ear hook portion 12. It should be noted that in some embodiments, the second shell 123 may not be provided, and the elastic connector 122 is directly connected to the first shell 1241, that is, the connection is provided at the free end of the elastic connector 122.

[0054] Preferably, in some embodiments, the housing 124 further includes a boss 1242 disposed in the end direction of the first housing 1241 away from the free end of the elastic connector 122, and the opening 1213 of the second covering section 1212 surrounds the periphery of the side wall disposed on the boss 1242, so that the opening 1213 can form a matching relationship with the boss 1242, thereby effectively improving the connection stability between the elastic covering body 121 and the housing 124, reducing the risk of relative movement between the elastic covering body 121 and the housing 124, and the elastic covering body 121 provided with the opening 1213 can completely cover the periphery of the housing 124 except the boss 1242, ensuring that in the wearing state, the position where the housing 124 is in abutting relationship with the head and the ear can be abutted with the head and the ear through the elastic covering body 121, thereby effectively improving the wearing comfort of the earphone 10. Specifically, in some embodiments, the boss 1242 and the first housing 1241 can be integrated. In some other embodiments, the boss 1242 and the first shell 1241 may be separately provided. For example, in some embodiments, the boss 1242 and the first shell 1241 may be assembled in an assembly manner.

[0055] Alternatively, if Figure 5-8As shown, in some embodiments, the second shell 123 is used as a transition piece connecting the elastic connector 122 and the first shell 1241, and one end of the second shell 123 is connected to the other end of the elastic connector 122 (that is, the end of the elastic connector 122 away from the movement module 11), and the cross-sectional area of ​​the second shell 123 gradually increases along the direction in which the elastic connector 122 is away from the movement module 11, forming an arc transition to improve wearing comfort. Preferably, in some embodiments, the first coating section 1211 is further coated on the periphery of the second shell 123 in a molding manner, which can effectively simplify the coating process of the first coating section 1211, and facilitate the first coating section 1211 to better adhere to the transition area between the elastic connector 122 and the accommodating shell 124.

[0056] Optionally, in some embodiments, the second covering section 1212 is attached to the outer wall of the first shell 1241, and such a configuration can effectively improve the connection stability between the second covering section 1212 and the first shell 1241. For example, in some embodiments, in a natural state (i.e., before being mounted on the first shell 1241), the radial dimension of the covering space formed by the second covering section 1212 is smaller than the radial dimension of the first shell 1241. With such a configuration, when the second covering section 1212 is mounted on the first shell 1241, the first shell 1241 supports the second covering section 1212 inside the second covering section 1212, so that the second covering section 1212 has a tendency to elastically contract toward the first shell 1241, and then attached to the outer wall of the first shell 1241, thereby effectively improving the connection stability between the second covering section 1212 and the first shell 1241. Furthermore, in some embodiments, in a natural state (i.e., not mounted on the first shell 1241), the radial dimension of the opening 1213 can also be set to be smaller than the radial dimension of the boss 1242. With this configuration, when the second covering section 1212 is mounted on the first shell 1241, the edge of the opening 1213 has a tendency to elastically contract toward the boss 1242, further improving the connection stability between the second covering section 1212 and the first shell 1241.

[0057] Alternatively, if Figure 7As shown, in some embodiments, the edge of the opening 1213 contacts the side wall of the boss 1242, or the gap J1 between the edge of the opening 1213 and the side wall of the boss 1242 is less than 0.2 mm. This arrangement can effectively prevent dust, sweat and other impurities from penetrating into the gap between the edge of the first shell 1241 and the side wall of the boss 1242, causing the ear hook 12 to bulge. In addition, when the radial size of the boss 1242 remains unchanged, the smaller the gap J1, the larger the area of ​​the bottom of the second covering section 1212 along the axial direction z1 of the housing 124 and the first housing 1241 abutting against each other, effectively reducing the risk of the second covering section 1212 and the housing 124 being separated.

[0058] See also Figure 7 The boss 1242 is a portion on the accommodating shell 124 that cooperates with the first shell 1241. The larger the radial dimension d1 of the boss 1242 is, the larger the radial dimension of the first shell 1241 will be set after the second covering section 1212 covers the periphery of the accommodating shell 124. This will cause the bottom of the second covering section 1212 along the axial direction z1 of the accommodating shell 124 to lack a large enough area to abut against the first shell 1241, thereby increasing the risk of the second covering section 1212 and the accommodating shell 124 being separated. Therefore, in some embodiments, the radial dimension d1 of the boss 1242 is smaller than the maximum radial dimension d2 of the first shell 1241. Such a configuration can effectively ensure that the bottom of the first shell 1241 (the bottom of the first shell 1241 is the bottom of the second shell 123 away from the axial direction z1 of the first shell 1241) will not be completely occupied by the boss 1242, so that there is a sufficiently large area at the bottom of the first shell 1241 to abut against the second covering section 1212, thereby effectively reducing the risk of the second covering section 1212 being detached from the accommodating shell 124.

[0059] Alternatively, if Figure 7 As shown, in some embodiments, the ratio of the radial dimension d1 of the boss 1242 to the maximum radial dimension d2 of the first shell 1241 is between 0.4 and 0.7. Such a configuration can further ensure that there is a sufficiently large area at the bottom of the first shell 1241 to abut against the second covering section 1212, thereby further reducing the risk of the second covering section 1212 being separated from the accommodating shell 124, while avoiding the difficulty of fitting due to the opening 1213 being too small.

[0060] Optionally, in some embodiments, when observed in the direction X1 toward the outer end surface of the boss 1242, the first shell 1241 and the boss 1242 are arranged in a circular shape. Such an arrangement makes the contour of the edge of the first shell 1241 and the contour of the side wall of the boss 1242 smoother, thereby reducing the risk of tearing when the second covering section 1212 is fitted onto the first shell 1241, thereby effectively improving the structural strength of the second covering section 1212, and setting the boss 1242 in a circular shape effectively improves the aesthetics of the ear hook portion 12 while reducing the molding complexity of the accommodating shell 124 and the second covering section 1212.

[0061] It is worth noting that in some embodiments, the direction X1 toward the outer end surface of the boss 1242 is parallel to the axial direction z1 of the first shell 1241 , and the mating direction of the first shell 1241 and the second shell 123 is parallel to the axial direction z1 of the accommodating shell 124 .

[0062] Optionally, in some embodiments, when observed in the direction toward the outer end of the boss 1242, the first shell 1241 is arranged in a circular shape, that is, along the axial direction z1 of the first shell 1241, the contour of the first shell 1241 is arranged in a circular shape (it should be noted that the circle referred to here can be understood as an elliptical or circular structure such as a perfect circle). For example, the first shell 1241 is an overall cylindrical structure. Such a configuration makes the side periphery of the first shell 1241 present a smooth arc surface, so that the second covering section 1212 abuts against the user's head and ears with a smooth arc surface, thereby effectively improving the wearing comfort of the headset 10. Further, the center of the first shell 1241 (i.e., the center of the circular outline of the first shell 1241 along the axial direction z1 of the first shell 1241) is concentrically arranged with the center of the boss 1242 (the center of the boss 1242 is also the center of the circular outline of the boss 1242 along the axial direction z1 of the first shell 1241), or the distance between the center of the first shell 1241 and the center of the boss 1242 is less than 5 mm. Since the relative position of the center of the first shell 1241 and the center of the boss 1242 will directly affect the relative position relationship between the first shell 1241 and the boss 1242, the first shell 1241 should be coaxially arranged with the boss 1242 as much as possible to ensure that the elastic resultant force of the elastic force of the second covering section 1212 on the first shell 1241 is as parallel as possible to the axial direction z1 of the first shell 1241, so as to prevent the elastic resultant force from affecting the matching stability between the first shell 1241 and the second shell 123, and can also effectively reduce the risk of the second covering section 1212 being separated from the first shell 1241. Therefore, setting the center of the first shell 1241 concentrically with the center of the boss 1242, or ensuring that the distance between the center of the first shell 1241 and the center of the boss 1242 is less than 5 mm, can effectively improve the connection stability between the first shell 1241 and the second shell 123, and can also effectively reduce the risk of the second covering section 1212 being separated from the first shell 1241.

[0063] Moreover, in some embodiments, when in the wearing state, the axial direction z1 of the first shell 1241 is set parallel to the sagittal plane, and the center of the boss 1242 is set concentrically with the center of the first shell 1241, which can effectively prevent the boss 1242 from contacting the user's head and ears, thereby effectively improving the wearing comfort of the headset 10.

[0064] Alternatively, if Figures 5 and 6As shown, in some embodiments, the outer surface of the free end of the first shell 1241 is tapered with an arc-shaped transition in the direction away from the second shell 123 (that is, the axial direction z1 of the first shell 1241 and away from the positive direction of the second shell 123). Such a configuration allows the outer surface of the bottom of the first shell 1241 to be arc-shaped, which can effectively improve the wearing comfort and aesthetics of the ear hook portion 12 to a certain extent while not affecting the connection stability between the second covering section 1212 and the first shell 1241.

[0065] Alternatively, if Figures 5 and 6 As shown, in some embodiments, the outer surface of the free end of the first shell 1241 is spherical, which can effectively improve the aesthetics and wearing comfort of the ear hook portion 12.

[0066] Alternatively, if Figure 8 As shown, in some embodiments, at the position of the boss 1242, the outer surface of the second covering section 1212 is flush with the outer end surface of the boss 1242, or the outer end surface of the boss 1242 protrudes from the outer surface of the second covering section 1212, and the protruding height g1 is not greater than 3 mm. Specifically, the boss 1242 is the part of the accommodating shell 124 exposed from the second covering section 1212, so the outer surface of the second covering section 1212 at the position of the boss 1242 is set flush with the outer end surface of the boss 1242, or the outer end surface of the boss 1242 protrudes from the outer surface of the second covering section 1212, and the protruding height g1 is set to be no more than 3 mm, which can effectively improve the integrity of the ear hook part 12, so as to improve the aesthetics of the earphone 10, and can also effectively reduce the risk of the boss 1242 contacting the ear and the head. Of course, in the actual assembly process, due to limited processing conditions or processing errors, it is difficult to make the outer surface of the second covering section 1212 at the position of the boss 1242 and the outer end surface of the boss 1242 absolutely flush. Therefore, in some embodiments, considering the above limitations, the outer surface of the second covering section 1212 and the outer end surface of the boss 1242 may have a height difference, and the absolute value of the height difference is within 0.01 mm. Such a setting can make the outer surface of the second covering section 1212 and the outer end surface of the boss 1242 almost flush, thereby effectively improving the aesthetics of the earphone 10.

[0067] like Figures 7 and 8As shown, in some embodiments, the second shell 123 includes a main body 1232 and an insertion portion 1231, the main body 1232 is connected to the elastic connecting member 122, the insertion portion 1231 is connected to one end of the main body 1232 facing the accommodating shell 124, the radial dimension of the insertion portion 1231 is smaller than the radial dimension of the main body 1232, and thus an annular table surface is formed at the connection between the insertion portion 1231 and the main body 1232, the accommodating shell 124 has an open end 1244, the insertion portion 1231 is inserted into the accommodating shell 124 from the open end 1244, and the open end 1244 further abuts against the annular table surface, at the position of the open end 1244, the outer surface of the accommodating shell 124 smoothly transitions with the outer surface of the main body 1232, and such a configuration makes the outer surface of the elastic covering body 121 present a smooth transition and a smooth contour as a whole, thereby effectively improving the wearing comfort of the earphone 10. The above method can also effectively reduce the maximum radial dimension of the ear hook portion 12, thereby effectively increasing and reducing the overall structural size of the earphone 10.

[0068] Optionally, in some embodiments, the earphone 10 also includes glue at least filling the space between the outer surface of the first shell 1241 and the second covering section 1212, and the glue maintains a certain distance from the peripheral side wall of the boss 1242. Such a configuration allows the first shell 1241 and the second covering section 1212 to be connected by glue, thereby effectively improving the connection stability between the first shell 1241 and the second covering section 1212, thereby effectively preventing the first shell 1241 and the second covering section 1212 from detaching.

[0069] Optionally, in this embodiment, if Figures 7 and 8 As shown, the first shell 1241 serves as the main body of the accommodating shell 124, and is used to form the accommodating chamber 1243. The second shell 123 serves as an adapter connecting the first shell 2141 and the elastic connecting member 122, and also serves as a cover of the first shell 1241. With such a configuration, during assembly, components such as batteries to be placed in the accommodating chamber 1243 can be pre-placed in the first shell 1241, and then the first shell 1241 and the second shell 123 can be docked, thereby effectively improving the assembly efficiency of components such as batteries.

[0070] Optionally, in some embodiments, the second shell 123 can serve as the main body of the accommodating shell 124, that is, the second shell 123 includes a connecting body (such as the main body 1232 of the above embodiment) connected to the elastic connecting member 122, and the second shell 123 also includes a accommodating body connected to the connecting shell and used to form a accommodating bin 1243 with an opening at one end. Further, the first shell 1241 serves as an end cover of the second shell 123, and is covered on the open end of the second shell 123 where the opening of the accommodating bin 1243 is provided to seal the accommodating bin 1243, wherein the open end of the second shell 123 is provided at the end of the second shell 123 away from the elastic connecting member 122, so that the overall length of the first shell 1241 along the axial direction z1 is smaller than the overall length of the second shell 123 along the axial direction z1. During assembly, the difficulty of sleeve-mounting the second covering end 1212 on the first shell 1241 can be effectively reduced, thereby effectively improving the assembly efficiency and convenience of the first shell 1241 and the second shell 123.

[0071] Alternatively, if Figure 4 , Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments, the earphone 10 further includes a microphone assembly 113, a housing space 1103 is provided inside the housing assembly 110, the microphone assembly 113 is provided in the housing space 1103, two sound inlet holes 1135 are provided on the housing assembly 110 to connect the housing space 1103 with the outside of the housing assembly 110, the sound inlet ends of the two sound inlet holes 1135 are spaced apart from each other, and a mounting groove is provided on the inner surface of the housing assembly 110 corresponding to the housing space 1103 area 1142, the sound outlet ends of the two sound inlet holes 1135 are connected to the mounting groove 1142, the microphone assembly 113 includes a sound guide seat 1132 and a microphone 1131, the sound guide seat 1132 is provided with a sound guide channel 1136, the sound guide seat 1132 is embedded in the mounting groove 1142, the sound input end of the sound guide channel 1136 is connected to the sound outlet ends of the two sound inlet holes 1135 in the mounting groove 1142, and the microphone 1131 is configured to receive the sound output by the sound outlet end of the sound guide channel 1136.

[0072] Specifically, the sound input end of the sound input hole 1135 may refer to one end where the external sound enters the sound input hole 1135, that is, one end connected to the outside world. The sound output end of the sound input hole 1135 may refer to one end where the external sound enters the sound guiding channel 1136 after passing through the sound input hole 1135. The sound input end of the sound guiding channel 1136 refers to one end where the external sound flowing out through the sound output end of the sound input hole 1135 enters the sound guiding channel 1136. The corresponding sound output end of the sound guiding channel 1136 refers to one end where the external sound flows out of the sound guiding channel 1136 after passing through the sound guiding channel 1136. Among them, the path between the sound input end of the sound input hole 1135 and the sound output end of the sound guiding channel 1136 can be referred to as a sound guiding path. Optionally, in some embodiments, the sound guiding channel 1136 can be set to a channel structure form such as a straight-through type, a curved type, a multi-layer surround type, etc.

[0073] Preferably, in some embodiments, two sound inlet holes 1135 are provided on the housing assembly 110, and external sound can flow into the sound guide channel 1136 through the two sound inlet holes 1135 and be transmitted to the microphone 1131, which can effectively improve the sound pickup effect of the microphone 1131. In addition, during the sound pickup process, there may be a large airflow entering the sound inlet holes 1135, and the airflow can enter the housing assembly 110 through one of the sound inlet holes 1135 and flow out through the other sound inlet hole 1135, which can slow down the airflow speed and reduce the probability of the airflow impacting the microphone 1131 through the sound guide channel 1136, thereby reducing the wind noise during sound pickup, thereby effectively improving the sound pickup effect of the microphone 1131.

[0074] Furthermore, in some embodiments, the sound inlet 1135 includes an extension channel connecting the sound inlet end and the sound outlet end of the sound inlet. In the wearing state, at least a portion of the extension channel close to the outside of the shell assembly 110 is tilted toward the back of the human body relative to the sagittal plane of the human body, and the angle between the extension direction of the extension channel and the sagittal plane is greater than or equal to 5° and less than or equal to 40°. This arrangement allows the extension channel of the sound inlet 1135 to extend tilted toward the back of the human ear when the earphone is worn on the human body, thereby reducing the influence of airflow and further improving the sound pickup effect.

[0075] Furthermore, in some embodiments, the mounting groove 1142 disposed on the inner side of the shell assembly 110 can provide a better positioning effect for the sound guide seat 1132 when installing the sound guide seat 1132, thereby effectively improving the installation accuracy and assembly efficiency of the sound guide seat 1132. Furthermore, the mounting groove 1142 is a semi-enclosed area with a single-end opening. After the sound guide seat 1132 is embedded in the area enclosed by the mounting groove 1142 along the groove opening of the mounting groove 1142, it is more conducive to the sealed connection between the mounting groove 1142 and the sound guide seat 1132, so that a better closed area can be formed between the sound input end of the sound guide channel 1136 provided on the sound guide seat 1132 and the sound output ends of the two sound input holes 1135, thereby effectively improving the air tightness of the sound guide path. In this way, not only can the airflow flowing out along the sound output end of the sound input hole 1135 be effectively prevented from flowing in the gap between the sound guide seat 1132 and the mounting groove 1142 to form noise, but the sound guide path with higher air tightness can also effectively reduce the probability of missing frequency bands of sound, thereby effectively improving the sound pickup effect of the microphone 1131.

[0076] Alternatively, if Figures 10 to 13 As shown, in some embodiments, the microphone assembly 113 further includes a circuit board 1133, which is a plate-shaped element provided with a processing circuit of the microphone 1131. Specifically, the sound guide seat 1132 is provided on one side of the circuit board 1133 facing the mounting slot 1142, and the microphone 1131 is provided on the other side of the circuit board 1133 away from the mounting slot 1142. The circuit board 1133 is provided with a connecting hole 1141, and the microphone 1131 is connected to the sound outlet end of the sound guide channel 1136 through the connecting hole 1141. Such a configuration effectively shortens the spatial interval between the microphone 1131 and the processing circuit of the microphone 1131, thereby effectively reducing the wiring distance between the microphone 1131 and the processing circuit of the microphone 1131, and improving the space utilization rate inside the housing assembly 110. Furthermore, in some embodiments, the microphone 1131 can be directly set on the circuit board 1133, and the microphone 1131 is routed through the board body of the circuit board 1133 to be connected to the microphone 1131 processing circuit, thereby eliminating the need to route the microphone 1131 through an additional circuit line, thereby further improving the space utilization inside the shell assembly 110 and effectively simplifying the overall structure of the earphone 10.

[0077] It should be noted that in this embodiment, the circuit board 1133 can be a main control circuit board 112 that integrates the microphone 1131 processing circuit and the main control circuit and other circuits. In other embodiments, the circuit board 1133 can also only have the microphone 1131 processing circuit as an exclusive circuit element of the microphone 1131.

[0078] Furthermore, in some embodiments, the circuit board 1133 also serves as a holding member to press and hold the sound guide seat 1132 in the mounting groove 1142. This arrangement can effectively improve the connection stability between the sound guide seat 1132 and the mounting groove 1142. In addition, the sound guide seat 1132, the circuit board 1133, and the microphone 1131 are stacked in this way, which effectively improves the internal space utilization of the housing assembly 110. Specifically, the side of the circuit board 1133 facing the inner wall is in contact with the side of the sound guide seat 1132 facing the inside of the earphone.

[0079] Alternatively, if Fig.10 and Fig.12 As shown, in some embodiments, the microphone assembly 113 further includes a seal 1137 disposed between the circuit board 1133 and the sound guide seat 1132, and the seal 1137 is disposed around the sound outlet end of the sound guide channel 1136 and the sound inlet end of the communication hole 1141. In this way, the seal 1137 can effectively seal the area between the circuit board 1133 and the sound guide seat 1132, so as to effectively seal the area between the sound outlet end of the sound guide channel 1136 and the sound inlet end of the communication hole 1141, thereby further improving the sound pickup effect of the microphone 1131. The seal 1137 can be a rubber ring, glue, etc.

[0080] Preferably, if Fig.10 and Fig.12 As shown, in some embodiments, an annular groove 1138 is provided on the circuit board 1133 or the sound guide seat 1132, and the seal 1137 is provided in the annular groove 1138, and the sound outlet end of the sound guide channel 1136 and the sound inlet end of the communication hole 1141 are located in the enclosed area of ​​the annular groove 1138. The annular groove 1138 can provide a better positioning for the seal 1137. During the assembly process, the seal 1137 is installed through the annular groove 1138, which can effectively improve the installation accuracy of the seal 1137 and effectively prevent the seal 1137 from blocking the sound outlet end of the sound guide channel 1136 and the sound inlet end of the communication hole 1141 due to the installation error of the seal 1137. In addition, the annular groove 1138 also has a good fixing effect. Installing the seal 1137 in the annular groove 1138 can effectively improve the connection stability between the seal 1137 and the circuit board 1133 and / or the sound guide seat 1132, and prevent the seal 1137 from shifting laterally relative to the sound guide seat 1132 and the circuit board 1133 due to factors such as vibration and extrusion, thereby affecting the sealing effect between the sound output end of the sound channel and the sound input end of the connecting hole 1141.

[0081] Optionally, in some embodiments, the seal 1137 is integrally formed with the sound guide seat 1132 and is arranged to protrude from the sound guide seat 1132 , which can effectively simplify the component structure of the earphone 10 and effectively improve the assembly efficiency of the earphone 10 .

[0082] Optionally, in some embodiments, the sound guide seat 1132 can be made of a material with a certain flexibility such as rubber.

[0083] Alternatively, if Fig.12 As shown, in some embodiments, along the spacing direction X2 between the sound guide seat 1132 and the two sound inlet holes 1135, the sound outlet ends of the two sound inlet holes 1135 are relatively spaced from the sound inlet end of the sound guide channel 1136, so as to form a larger spacing space between the sound inlet end of the sound guide channel and the sound outlet ends of the two sound inlet holes 1135, thereby reducing the flow rate of the airflow to a certain extent, thereby effectively reducing the wind noise during sound pickup, and effectively improving the sound pickup effect of the microphone 1131. In addition, the spacing between the sound inlet end of the sound guide channel 1136 and the sound outlet ends of the two sound inlet holes 1135 can also effectively reduce the probability of the airflow directly flowing into the sound guide channel 1136, thereby effectively reducing the probability of the airflow impacting the microphone 1131, thereby effectively improving the sound pickup effect of the microphone 1131.

[0084] It is worth noting that in any embodiment of the earphone 10 in this document, the spacing direction X2 between the sound guide seat 1132 and the two sound inlet holes 1135 is arranged parallel to the thickness direction X of the shell assembly 110.

[0085] Preferably, if Fig.13 As shown, in some embodiments, the sound outlet ends of the two sound inlet holes 1135 are located at the bottom of the mounting groove 1142, and the bottom of the mounting groove 1142 is provided with a first groove 1139 that is recessed in the direction away from the sound guide seat 1132, and the sound outlet ends of the two sound inlet holes 1135 are connected to each other through the first groove 1139. Specifically, the first groove 1139 provides a communication channel for the two sound inlet holes 1135, so that the airflow flowing in from one of the two sound inlet holes 1135 can smoothly flow along the first groove 1139 to the other of the two sound inlet holes 1135, and then flow out of the earphone 10, thereby effectively slowing down the flow rate of the airflow, thereby effectively improving the sound pickup effect of the microphone 1131. In addition, the first groove 1139 can also effectively expand the spacing distance between the sound outlet ends of the two sound inlet holes 1135 and the sound inlet end of the sound guide channel 1136 and the size of the spacing space, thereby effectively slowing down the flow rate of the airflow, thereby effectively improving the sound pickup effect of the microphone 1131.

[0086] Preferably, if Fig.13As shown, in some embodiments, the groove depth c1 of the first groove 1139 is set to 0.25-0.55 mm, for example, 0.25 mm, 0.30 mm, 0.4 mm, 0.55 mm, etc., which are actual values ​​between 0.25-0.55 mm, so that the space utilization rate of the housing assembly 110 can be effectively ensured, and the sound pickup effect of the microphone 1131 can be effectively improved. Specifically, if the groove depth c1 of the first groove 1139 is too deep, the thickness of the housing assembly 110 must be increased to ensure the hole depth of the sound inlet hole 1135 to ensure the sound guiding effect. Increasing the thickness of the housing assembly 110 will inevitably reduce the size of the internal space of the housing assembly 110 and affect the arrangement of other parts of the earphone 10 when the overall structural size of the earphone 10 remains unchanged. On the contrary, if the groove depth c1 of the first groove 1139 is too shallow, the airflow cannot be well guided from one sound inlet hole 1135 to another sound inlet hole 1135, thereby affecting the sound pickup effect of the microphone 1131.

[0087] Alternatively, if Fig.10 and Fig.11 As shown, in some embodiments, the earphone 10 also includes a sound resistance net 1134, and the bottom of the mounting groove 1142 reserves an annular table 1143 at the sound outlet ends of the two sound inlet holes 1135 and the periphery of the first groove 1139, and the sound guide seat 1132 presses and fixes the sound resistance net 1134 on the annular table 1143, and the sound resistance net 1134 further covers the sound outlet ends of the two sound inlet holes 1135 and the first groove 1139.

[0088] Alternatively, if Fig.12 As shown, in some embodiments, a second groove 1140 is provided on one side of the sound guide seat 1132 facing the two sound inlet holes 1135, which is recessed in a direction away from the two sound inlet holes 1135. The sound outlet ends of the two sound inlet holes 1135 are further connected to each other through the second groove 1140, and the sound inlet end of the sound guide channel 1136 is arranged in the second groove 1140. Specifically, the second groove 1140 cooperates with the first groove 1139 to form a connecting channel of the two sound inlet holes 1135, which can effectively increase the spacing distance between the sound outlet ends of the two sound inlet holes 1135 and the sound inlet end of the sound guide channel, thereby further reducing the flow rate of the airflow, thereby further improving the sound pickup effect of the microphone 1131. Furthermore, a second groove 1140 is provided on the sound guide seat 1132. This can effectively increase the spacing distance between the sound output ends of the two sound input holes 1135 and the sound input end of the sound guide channel while effectively reducing the influence of the first groove 1139 on the space utilization rate of the shell assembly 110 (specifically, how the groove depth c1 of the first groove 1139 affects the space utilization rate of the shell assembly 110 can be found in the above content and will not be elaborated in this article). This can further reduce the flow rate of the airflow and further improve the sound pickup effect of the microphone 1131.

[0089] Preferably, in some embodiments, an annular flange 1144 is provided on one side of the sound guide seat 1132 facing the two sound inlet holes 1135, and the annular flange 1144 is arranged to form a second groove 1140. The annular flange 1144 is embedded in the mounting groove 1142, and the sound resistance net 1134 is pressed and fixed on the annular table 1143. The sound resistance net 1134 further covers the sound outlet ends of the two sound inlet holes 1135 and the first groove 1139.

[0090] Specifically, the acoustic resistance net 1134 is arranged between the sound outlet ends of the two sound inlet holes 1135 and the sound input end of the sound guiding channel 1136 in the above-mentioned manner, which can effectively slow down the flow rate of the airflow flowing in through the two sound inlet holes 1135, thereby effectively reducing the probability of the airflow impacting the microphone 1131 through the sound guiding channel 1136, thereby reducing the wind noise during sound pickup, thereby effectively improving the sound pickup effect of the microphone 1131.

[0091] Optionally, in some embodiments, the extension direction of the mesh of the sound resistance net 1134 is at least partially set to cross the spacing direction X2. Such a setting can effectively increase the airflow blocking effect of the sound resistance net 1134, thereby effectively reducing the probability of the airflow impacting the microphone 1131 through the sound guiding channel 1136, thereby reducing wind noise during sound pickup, thereby effectively improving the sound pickup effect of the microphone 1131.

[0092] Optionally, in some embodiments, the acoustic network includes at least a gauze mesh and a steel mesh stacked along the spacing direction X2, wherein the steel mesh may be a 3D woven mesh, and the angle between the extension direction of the mesh of the steel mesh and the spacing direction X2 is 45°, which can effectively improve the airflow blocking effect of the steel mesh.

[0093] Optionally, in some embodiments, the acoustic network includes at least two layers of steel mesh stacked along the spacing direction X2 to further improve the sound pickup effect.

[0094] Alternatively, if Fig.12 As shown, in some embodiments, the sound guide seat 1132 is supported on the bottom of the mounting groove 1142 , and the projection of the first groove 1139 along the spacing direction X2 falls into the second groove 1140 .

[0095] Preferably, in some embodiments, the groove depth c2 of the second groove 1140 is set to 0.2-0.5 mm, for example, 0.25 mm, 0.30 mm, 0.4 mm, 0.50 mm, etc., which are actual values ​​between 0.25-0.50 mm, so that the structural size of the sound guide seat 1132 can be set more reasonably, so as to ensure the space utilization of the shell assembly 110, and effectively improve the spacing distance between the sound output ends of the two sound input holes 1135 and the sound input end of the sound guide channel, thereby effectively improving the sound pickup effect of the microphone 1131. Specifically, if the groove depth c2 of the second groove 1140 is too large, the structural size of the sound guide seat 1132 will be increased, thereby affecting the space utilization of the shell assembly 110. If the groove depth c2 of the second groove 1140 is too small, the spacing distance between the sound output ends of the two sound input holes 1135 and the sound input end of the sound guide channel will be reduced.

[0096] Optionally, in some embodiments, the projection of the sound input end of the sound guiding channel 1136 along the spacing direction X2 is at least partially located in the spacing area between the two sound input holes 1135. In this way, the projection of the sound input end of the sound guiding channel 1136 along the spacing direction X2 does not completely overlap with the projection of the sound output end of any one of the two sound input holes 1135, thereby effectively preventing the airflow from flowing out along the sound output end of one of the sound input holes 1135 and then directly flowing into the sound guiding channel 1136, thereby effectively improving the sound pickup effect of the microphone 1131.

[0097] Optionally, in some embodiments, the sound input end of the sound guiding channel 1136 has a center line z2 parallel to the spacing direction X2, and the sound output ends of the two sound input holes 1135 both have center lines (z3 and z4) parallel to the spacing direction X2, wherein the center line z2 of the sound input end of the sound guiding channel 1136 is located between the center lines z3 and z4 of the sound output ends of the two sound input holes 1135, and the center line z2 of the sound input end of the sound guiding channel 1136 and the center lines (z3 and z4) of the sound output ends of the two sound input holes 1135 are both located in the same vertical plane, so that the sound guiding channel 1136 is The projection of the sound input end of the sound channel 1136 along the spacing direction X2 includes a first projection portion overlapping with the projection of the sound output end of one of the sound input holes 1135, a second projection portion overlapping with the projection of the sound output end of the other sound input hole 1135, and a third projection portion not overlapping with the projections of the sound output ends of the two sound input holes 1135, wherein the areas of the first projection portion and the second projection portion are equal. Such an arrangement can effectively reduce the difference in sound introduced into the sound guide channel 1136 along the two sound input holes 1135, thereby effectively improving the sound pickup effect of the microphone 1131.

[0098] Optionally, in some embodiments, the two sound inlet holes 1135 have the same structure, which can effectively reduce the difference in sound introduced through the two sound inlet holes 1135 , thereby effectively improving the sound pickup effect of the microphone 1131 .

[0099] Alternatively, if Figure 3 and Figure 4 As shown, in some embodiments, the shell assembly 110 includes a first shell 1101 and a second shell 1102 that mate along a preset mating direction, wherein the preset mating direction is arranged parallel to the thickness direction X of the shell assembly 110, and, in a worn state, along the preset mating direction, the first shell 1101 is arranged close to the ear, and the second shell 1102 is arranged away from the ear, wherein the mounting groove 1142 and two sound input holes 1135 are arranged on the second shell 1102, and the sound input ends of the two sound input holes 1135 are located on the side of the second shell 1102 away from the first shell 1101 along the thickness direction, thereby effectively preventing the sound input ends of the two sound input holes 1135 from being blocked by the ears or head of the user, thereby effectively improving the sound pickup effect of the microphone 1131.

[0100] Alternatively, if Figure 4 , Fig.12 and Fig.13 As shown, the housing assembly 110 further includes a flexible covering layer 1104, which covers at least the outer surface of the second housing 1102 at the position where the sound inlet holes 1135 are provided, wherein the positions of the flexible covering layer 1104 corresponding to the two sound inlet holes 1135 are provided with through holes corresponding to the two sound inlet holes 1135, wherein the two through holes are respectively used as extensions 1155 of the sound inlet ends of the two sound inlet holes 1135, so that the two sound inlet holes 1135 are connected to the inner and outer sides of the housing assembly 110. Further, the flexible covering layer 1104 is provided at the outer surface of the position where the sound inlet holes 1135 are provided on the second housing 1102, and the flexible covering layer 1104 can, to a certain extent, block the noise of the external environment, thereby reducing the noise flowing into the sound guide channel 1136, thereby effectively improving the sound pickup effect of the microphone 1131.

[0101] Optionally, in some embodiments, the flexible covering layer 1104 completely covers the outer surface of the second shell 1102 .

[0102] Alternatively, if Fig.14As shown, in some embodiments, the speaker 111 is an air conduction speaker 111, wherein the speaker 111 includes a diaphragm 1111, a fixing ring 1112 and a basin frame 1114, the diaphragm 1111 includes a vibration body 1111a and an annular fixing portion 1111b connected to the vibration body 1111a and arranged around the periphery of the vibration body 1111a, the fixing ring 1112 is connected and fixed to the annular fixing portion 1111b, and is sleeved on the basin frame 1114, and a first connection length L1 is provided between the annular fixing portion 1111b and the fixing ring 1112 along the axial direction z5 of the speaker 111, and a second connection length L2 is provided along the radial direction of the speaker 111, and the first connection length L1 is greater than the second connection length L2.

[0103] Specifically, the diaphragm 1111 includes a vibration body 1111a and an annular fixing portion 1111b. The vibration body 1111a can move relative to the basin frame 1114 and the annular fixing portion 1111b along the preset vibration direction of the speaker 111 under electromagnetic action to convert the electromagnetic signal into sound. The annular fixing portion 1111b is relatively fixed to the basin frame 1114 through the fixing ring 1112, that is, the fixing ring 1112 is sleeved on one end of the basin frame 1114 and fixedly connected to the basin frame 1114, and the annular fixing portion 1111b is fixedly connected to the fixing ring 1112. In this way, the diaphragm 1111 is fixed to the basin frame 1114 through the fixing ring 1112. The basin frame 1114 is used to fix the sound-generating components including the diaphragm 1111, the magnetic circuit assembly 1115 and the voice coil 1113 in the housing assembly 110. When the diaphragm 1111 is vibrating, part of the vibration energy is transmitted to the basin frame 1114, and then to the housing assembly 110 and even the entire earphone 10, so that the entire earphone 10 generates some noise that interferes with the normal sound of the speaker 111, thereby affecting the sound quality of the earphone 10. Therefore, a fixing ring 1112 is provided between the basin frame 1114 and the diaphragm 1111, so that the diaphragm 1111 is fixedly connected to the basin frame 1114 through the fixing ring 1112, thereby effectively reducing the vibration energy transmitted from the diaphragm 1111 to the basin frame 1114, thereby effectively reducing the noise caused by the earphone 10 and effectively improving the sound quality of the earphone 10. Preferably, the material of the fixing ring 1112 may include a certain flexible material, so that the fixing ring 1112 has structural rigidity and a certain flexibility, which can further reduce the vibration energy transmitted from the diaphragm 1111 to the basin frame 1114, thereby effectively reducing the noise caused by the earphone 10 and effectively improving the sound quality of the earphone 10. Preferably, the fixing ring 1112 and the annular fixing portion 1111b and / or the fixing ring 1112 and the basin frame 1114 can be fixedly connected by glue or the like in a dispensing manner, which can further reduce the vibration energy transmitted from the diaphragm 1111 to the basin frame 1114, thereby effectively reducing the noise caused by the earphone 10 and effectively improving the sound quality of the earphone 10.

[0104] Specifically, in some embodiments, the connection between the annular fixing portion 1111b and the fixing ring 1112 includes a lateral connection (i.e., a first connection length L1 is set between the annular fixing portion 1111b and the fixing ring 1112 as described above) and a radial connection (i.e., a second connection length L2 is set between the annular fixing portion 1111b and the fixing ring 1112 as described above). Preferably, in some embodiments, the connection between the annular fixing portion 1111b and the fixing ring 1112 is mainly a lateral connection, and a radial connection is supplemented (i.e., the first connection length L1 described above is greater than the second connection length L2). Among them, the radial connection method serves as an auxiliary connection between the annular fixing portion 1111b and the fixing ring 1112. On the premise that the lateral connection method is sufficient to maintain the connection stability between the annular fixing portion 1111b and the fixing ring 1112, the radial connection method may not be set between the annular fixing portion 1111b and the fixing ring 1112. In other words, the first connection length L1 cannot be less than zero, and the second connection length L2 can be set to zero.

[0105] It should be noted that the annular fixing portion 1111b and the fixing ring 1112 are connected mainly by lateral connection and supplemented by radial connection. This can ensure the connection stability between the annular fixing portion 1111b and the fixing ring 1112 while effectively reducing the radial size of the fixing ring 1112, thereby effectively reducing the radial size of the speaker 111, and further effectively reducing the overall volume of the speaker 111. Specifically, the diaphragm 1111 is the main component for vibrating and sounding, and its radial dimensions, especially the radial dimensions of the vibration body 1111a, will directly affect the sound quality of the speaker 111. Generally, the larger the radial dimensions of the vibration body 1111a, the better the sound quality of the speaker 111. Therefore, the annular fixing portion 1111b and the fixing ring 1112 are mainly connected through a lateral connection. On the premise of ensuring the connection stability between the annular fixing portion 1111b and the fixing ring 1112, the radial dimension of the vibration body 1111a of the diaphragm 1111 can be made larger (it can also be understood that the speaker 111 can be configured with a diaphragm 1111 with a vibration body 1111a with a larger radial dimension), thereby effectively improving the sound quality of the speaker 111 while effectively reducing the overall volume of the speaker 111.

[0106] Optionally, in some embodiments, the ratio between the first connection length L1 and the second connection length L2 is greater than 4, which can effectively improve the connection stability between the diaphragm 1111 and the fixing ring 1112, effectively improve the sound quality of the speaker 111, and effectively reduce the overall volume of the speaker 111. Specifically, the smaller the ratio of the first connection length L1 to the second connection length L2, the larger the radial size of the fixing ring 1112 is required to connect to the diaphragm 1111, and the larger the radial size of the fixing ring 1112, the larger the radial size of the speaker 111.

[0107] Optionally, preferably, in some embodiments, the first connection length L1 is not less than 0.5 mm, for example, the first connection length L1 can be 0.5 mm, 0.6 mm, 0.8 mm, 0.9 mm, etc., which are actual values ​​not less than 0.5 mm, so as to ensure the connection stability between the fixing ring 1112 and the annular fixing portion 1111b. Specifically, the fixing ring 1112 and the annular fixing portion 1111b are mainly connected by a lateral connection method, and the first connection length L1 should not be too small. If the first connection length L1 is too small, the connection between the fixing ring 1112 and the annular fixing portion 1111b will be unstable, thereby affecting the sound quality of the speaker 111. Preferably, in some embodiments, the first connection length L1 can be any value between 0.5 and 1.5 mm, for example, the first connection length L1 can be 0.5 mm, 0.6 mm, 0.8 mm, 0.9 mm, 1.5 mm, etc., which are actual values ​​between 0.5 and 1.5 mm.

[0108] Preferably, in some embodiments, the second connection length L2 is not greater than 0.2 mm. For example, the second connection length L2 can be 0 mm, 0.1 mm, 0.12 mm, 0.15 mm, etc., which are actual values ​​not greater than 0.2 mm to reduce the radial size of the speaker 111. Specifically, the fixing ring 1112 and the annular fixing portion 1111b are mainly connected by lateral connection. When the connection strength is sufficient, the second connection length L2 can be minimized to control the radial size of the fixing ring 1112 to be smaller, thereby further reducing the radial size of the speaker 111.

[0109] It should be noted that when there is only a lateral connection between the annular fixing portion 1111b and the fixing ring 1112 (that is, when the second connection length L2 is set to zero), there is no ratio between the first connection length L1 and the second connection length L2, or the ratio tends to infinity. At this time, the value of the first connection length L1 should be at least greater than the preset length threshold, and the preset length threshold is the minimum value that can ensure the connection stability between the annular fixing portion 1111b and the fixing ring 1112.

[0110] Alternatively, if Figures 15 to 16As shown, in some embodiments, the fixing ring 1112 includes a cylindrical body 1112a mounted on a basin frame 1114, a height H4 of the cylindrical body 1112a along the axial direction z5 is greater than a radial wall thickness H3 of the cylindrical body 1112a, an annular fixing portion 1111b is connected and fixed to an inner circumference or an outer circumference of the cylindrical body 1112a to form a first connection length L1, the annular fixing portion 1111b is also connected and fixed to an end face of the cylindrical body 1112a (that is, an end face of the cylindrical body 1112a close to the vibrating body 1111a along the axial direction z5) to form a second connection length L2; or the annular fixing portion 1111b is only connected and fixed to the inner circumference or the outer circumference of the cylindrical body 1112a, so that the second connection length L2 is zero.

[0111] It should be noted that the cylindrical body 1112a can be understood as the overall structure of the cylindrical body 1112a being set in a cylindrical shape, wherein along the axial direction z5, the outline of the cylindrical body 1112a can be set based on the structural form of the diaphragm 1111, for example, along the axial direction z5, the overall structural form of the diaphragm 1111 can be runway-shaped, circular or square, etc., and correspondingly, along the axial direction z5, the outline of the cylindrical body 1112a can be set to a runway-shaped, circular or square structural form.

[0112] Specifically, in some embodiments, the annular fixing portion 1111b includes a first folded edge 1111c which is arranged around the outer peripheral side of the vibration body 1111a and connected to the vibration body 1111a, and a second folded edge 1111d which is connected to the first folded edge 1111c, wherein the second folded edge 1111d is an annular folded edge extending along the axial direction z5 of the speaker 111, and the second folded edge 1111d is connected and fixed to the outer peripheral surface or the inner peripheral surface of the cylindrical body 1112a to form a first connection length L1. The first folded edge 1111c is an annular folded edge extending radially along the speaker 111, and the first folded edge 1111c is connected and fixed to the end face of the cylindrical body 1112a (that is, the end face of the cylindrical body 1112a close to the vibration body 1111a along the axial direction z5) to form a second connection length L2, so that the annular fixing portion 1111b is connected and fixed mainly by a lateral connection method and supplemented by a radial connection method (that is, a second connection length L2 is set between the annular fixing portion 1111b and the cylindrical body 1112a), thereby effectively improving the sound quality of the speaker 111 while effectively reducing the overall volume of the speaker 111.

[0113] Alternatively, if Figures 15 to 16As shown, in some embodiments, the diaphragm 1111 is connected and fixed to the inner circumference or outer circumference of the cylindrical body 1112a only by the second folded edge 1111d, that is, only the first connection length L1 is set between the annular fixing portion 1111b and the fixing ring 1112, and the second connection length L2 is set to zero. This can further improve the sound quality of the speaker 111 while further reducing the overall volume of the speaker 111.

[0114] Optionally, in some embodiments, the annular fixing portion 1111b may not be provided with the first folded edge 1111c, and the outer peripheral edge of the vibration body 1111a directly extends toward the axial direction z5 of the speaker 111 to form a second folded edge 1111d. The second folded edge 1111d is connected and fixed to the outer peripheral surface or the inner peripheral surface of the cylindrical body 1112a to form a first connection length L1, thereby further improving the sound quality of the speaker 111 while further reducing the overall volume of the speaker 111.

[0115] Optionally, in some embodiments, the outer circumference of the cylindrical body 1112a is the outer side wall of the cylindrical body 1112a along the radial direction of the speaker 111 , and the inner circumference of the cylindrical body 1112a may be the inner side wall of the cylindrical body 1112a along the radial direction of the speaker 111 .

[0116] Optionally, in some embodiments, the end surface of the cylindrical body 1112a along the axial direction z5 close to the vibration body 1111a is recessed along the axial direction z5 of the speaker 111 to form an annular groove, wherein the inner circumferential surface of the cylindrical body 1112a is the groove wall of the annular groove, and the second folded edge 1111d is inserted into the annular groove 1138 to connect with the groove wall of the annular groove, thereby forming a first connection length L1.

[0117] Alternatively, if Fig.16As shown, in some embodiments, the annular fixing portion 1111b has a thickness H1 in the radial direction, and the thickness H1 is less than the first connection length L1. Specifically, the annular fixing portion 1111b has a thickness in the radial direction, which is the thickness of the second folded edge 1111d. If the thickness H1 of the annular fixing portion 1111b is too large, the radial size of the speaker 111 will increase. If the thickness H1 of the annular fixing portion 1111b is too small, the structural strength of the annular fixing portion 1111b will be affected, thereby affecting the connection stability between the annular fixing portion 1111b and the fixing ring 1112. Therefore, setting the thickness H1 of the annular fixing portion 1111b to be less than the first connection length L1 can effectively reduce the radial size of the speaker 111, thereby reducing the volume of the speaker 111. Moreover, in some embodiments, the thickness H1 of the annular fixing portion 1111b should also be no less than a preset thickness threshold, and the ratio of the first connection length L1 to the thickness H1 is greater than or equal to 5 and less than or equal to 15, which can effectively improve the connection stability between the annular fixing portion 1111b and the fixing ring 1112.

[0118] Alternatively, if Fig.16 As shown, in some embodiments, the ratio between the height H4 of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a is greater than 6.6, and the ratio between the first connection length L1 and the height H4 of the cylindrical body 1112a is greater than 0.4. Specifically, if the ratio between the height H4 of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a directly affects the connection stability between the cylindrical body 1112a and the annular fixing portion 1111b and the radial dimension of the speaker 111, the ratio between the height H4 of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a is set to be greater than 6.6, which can effectively improve the connection stability between the cylindrical body 1112a and the annular fixing member, and can also effectively reduce the overall volume of the speaker 111. Further, the height H4 of the cylindrical body 1112a is designed based on the first connection length L1, so that it can effectively ensure that after the cylindrical body 1112a is connected to the annular fixing portion 1111b, a first connection length L1 of a sufficiently large size can be formed to effectively improve the connection stability between the cylindrical body 1112a and the annular fixing portion 1111b. Therefore, limiting the ratio between the first connection length L1 and the height H4 of the cylindrical body 1112a to be greater than 0.4 can ensure that after the cylindrical body 1112a is connected to the annular fixing portion 1111b, a first connection length L1 of a sufficiently large size can be formed to effectively improve the connection stability between the cylindrical body 1112a and the annular fixing portion 1111b.

[0119] Alternatively, if Figures 15 to 16As shown, in some embodiments, the fixing ring 1112 further includes an annular flange 1112b protruding radially on the outer peripheral surface of the cylindrical body 1112a. Specifically, the annular flange 1112b is disposed at one end of the cylindrical body 1112a close to the basin frame 1114, so that the annular flange 1112b serves as a reinforcing structure of the cylindrical body 1112a, thereby effectively increasing the structural strength of the cylindrical body 1112a, especially the bending strength of the cylindrical body 1112a, and thus effectively improving the connection stability between the cylindrical body 1112a and the annular fixing portion 1111b.

[0120] Alternatively, if Fig.16 As shown, in some embodiments, the ratio between the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a is between 0.66 and 1.0. Specifically, if the ratio between the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a is too large, the radial size of the speaker 111 will be increased, and if the ratio between the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a and the wall thickness H3 of the cylindrical body 1112a is too small, the structural strength of the cylindrical body 1112a will be reduced. Therefore, setting the ratio of the protruding distance of the annular flange 1112b relative to the outer circumferential surface of the cylindrical body 1112a to the wall thickness of the cylindrical body 1112a between 0.66 and 1.0 can effectively improve the structural strength of the cylindrical body 1112a, so as to effectively improve the connection stability between the cylindrical body 1112a and the annular fixing part 1111b, and can also effectively reduce the overall volume of the speaker 111.

[0121] Alternatively, if Fig.14 and Fig.16As shown, in some embodiments, the annular fixing portion 1111b is connected and fixed to the outer circumference of the cylindrical body 1112a, and the radial thickness H1 of the annular fixing portion 1111b is smaller than the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a. Specifically, as described above, the radial thickness H1 of the annular fixing portion 1111b is the thickness of the second folded edge 1111d, wherein the thickness of the second folded edge 1111d is smaller than the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a. Based on this, while the inner circumference of the second folded edge 1111d is connected to the outer circumference of the cylindrical body 1112a, along the axial direction z5 of the speaker 111, the end face of the second folded edge 1111d close to the annular flange 1112b can also be connected to the annular flange 1112b to form a third connection length L3, thereby further improving the connection stability between the annular fixing portion 1111b and the cylindrical body 1112a. Among them, the third connection length L3 is greater than zero, and in some embodiments, the third connection length L3 is greater than or equal to the thickness H1 of the annular fixing portion 1111b in the radial direction, and is less than the protruding distance H2 of the annular flange 1112b relative to the outer circumference of the cylindrical body 1112a, so as to ensure that the second folded edge 1111d has a sufficient connection area on the annular flange 1112b, so that the connection strength at this location is not weaker than that at other locations, and at the same time, it can also be protected by the annular flange 1112b. Further, in some embodiments, the third connection length L3 is equal to the thickness H1 of the annular fixing portion 1111b in the radial direction.

[0122] Alternatively, if Fig.14 and Fig.16 As shown, in some embodiments, as described above, along the radial direction of the speaker 111, the annular flange 1112b and the annular fixing portion 1111b further have a third connection length L3, wherein the third connection length is equal to the thickness H1 of the annular fixing portion 1111b.

[0123] Optionally, in some embodiments, the basin frame 1114 includes an insertion portion 1114a and a support portion 1114b connected to each other in the axial direction, the radial dimension of the support portion 1114b is larger than the radial dimension of the insertion portion 1114a, and an annular table 1114c is formed at the connection between the insertion portion 1114a and the support portion 1114b, the insertion portion 1114a is inserted into the cylindrical body 1112a, and the annular flange 1112b is supported on the annular table 1114c. The basin frame 1114 forms the annular table 1114c in the above manner, and the annular flange 1112b is supported on the annular table 1114c. Such a configuration can effectively increase the connection area between the fixing ring 1112 and the basin frame 1114, thereby effectively improving the connection stability between the fixing ring 1112 and the basin frame 1114. Furthermore, since the vibration direction of the diaphragm 1111 (that is, the preset vibration direction) is parallel to the axial direction z5, when the diaphragm 1111 vibrates, there is a risk that the fixing ring 1112 will fall off the basin frame 1114 along the axial direction z5. Therefore, the fixing ring 1112 is fixed on the annular table 1114c. The annular table 1114c can provide the fixing ring 1112 with a supporting force along the axial direction z5, thereby effectively reducing the risk of the fixing ring 1112 falling off the basin frame 1114 along the axial direction z5, thereby effectively improving the connection stability between the fixing ring 1112 and the basin frame 1114.

[0124] Optionally, in some embodiments, a glue groove 1114d is provided on the annular table 1114c, and the fixing ring 1112 covers the glue groove 1114d. When assembling the fixing ring 1112 and the basin frame 1114, fixing glue can be added into the glue groove 1114d to strengthen the connection stability between the basin frame 1114 and the fixing ring 1112.

[0125] Optionally, in some embodiments, along the radial direction (radial direction of the speaker 111), the glue sol groove is arranged close to the outer peripheral side of the insertion portion 1114a, so that the glue containing groove 1114d is away from the outer peripheral side of the support portion 1114b. When the basin frame 1114 and the fixing ring 1112 are fixedly connected by fixing glue, the risk of the fixing glue overflowing to the outer peripheral side of the support portion 1114b can be reduced.

[0126] Optionally, as described above, the speaker 111 further includes: a magnetic circuit assembly 1115 and a voice coil 1113. The magnetic circuit assembly 1115 is used to form a magnetic gap, and the basin frame 1114 is arranged around the outer periphery of the magnetic circuit assembly 1115 and is relatively fixedly arranged with the magnetic circuit assembly 1115. One end of the voice coil 1113 is fixedly connected to the vibration body 1111a, and the other end extends into the magnetic gap, and is coupled with the magnetic circuit assembly 1115 under the action of an electrical signal, thereby driving the vibration body 1111a to reciprocate along the axial direction z5, thereby generating sound.

[0127] Optionally, in some embodiments, the axial direction z5 of the speaker 111 of any of the above embodiments is arranged parallel to the thickness direction X of the shell assembly 110 .

[0128] Alternatively, if Figures 17 to 22 As shown, in some embodiments, the earphone 10 includes an antenna pattern 115, and the antenna pattern 115 includes a first antenna pattern 115a and a second antenna pattern 115b. The first antenna pattern 115a is a component of the earphone 10 for receiving and / or transmitting Bluetooth signals. A feeding point 1151b for receiving a feeding signal is provided on the first antenna pattern 115a. When a feeding signal (i.e., an alternating electrical signal) is output to the feeding point 1151b on the first antenna pattern 115a, a changing current is formed on the first antenna pattern 115a. The second antenna pattern 115b can be further coupled with the first antenna pattern 115a to disperse the current on the first antenna pattern 115a, thereby preventing the current generated based on the feeding signal from being completely concentrated on the first antenna pattern 115a, thereby effectively reducing the SAR value of the antenna pattern 115.

[0129] Specifically, the main surface of the first antenna pattern 115a is the extension plane of the first antenna pattern 115a. In some embodiments, the main surface of the first antenna pattern 115a is perpendicular to the thickness direction X of the housing assembly 110. In some embodiments, the first antenna pattern 115a has a starting end 1151a (the starting end 1151a has an end point G) and a free end 1152a (the free end 1152a has an end point H), and extends from the end point G of the starting end 1151a to the end point H of the free end 1152a, thereby forming an extension direction. In different embodiments, the extension direction can be a straight line or a curve.

[0130] Optionally, in some embodiments, the first antenna pattern 115a can be bent along its extension direction to form a first semi-enclosed structure with a first opening 115c. That is, the overall structure of the first antenna pattern 115a presents a curved semi-enclosed structure, which can ensure that the length of the first antenna pattern 115a can meet the requirements of transmitting and / or receiving Bluetooth signals, and at the same time effectively improve the space utilization of the first antenna pattern 115a, thereby effectively reducing the overall structural size of the headset 10.

[0131] Specifically, the opening direction of the first antenna pattern 115a is defined as, when observed along the direction toward the main surface of the first antenna pattern 115a, a line connecting the endpoint G of the starting end 1151a and the endpoint H of the free end 1152a of the first antenna pattern 115a forms a line segment GH, and the direction perpendicular to the line segment GH and pointing to the outside of the first semi-closed structure is the first opening direction X3.

[0132] Furthermore, in some embodiments, when observed in the direction toward the main surface of the first antenna pattern 115a, the projection of the second antenna pattern 115b along the direction opposite to the opening direction of the first antenna pattern 115a (i.e., the first opening direction X3) at least partially overlaps with the first antenna pattern 115a. Such a configuration enables the second antenna pattern 115b to be at least partially located inside the first semi-closed structure formed by the first antenna pattern 115a or to be located on one side of the first semi-closed structure along the first opening direction X3. Such a configuration can effectively improve the overall space utilization of the antenna pattern 115, so that the antenna pattern 115 can be arranged on the earphone 10 with a smaller spatial structure size.

[0133] Furthermore, if Figure 20 to Figure 22 As shown, in some embodiments, the arc-chord ratio of the first antenna pattern 115a is not less than 2. Specifically, the arc-chord ratio of the first antenna pattern 115a is the ratio of the extended length of the first antenna pattern 115a to the line segment GH connecting the two end points (end point G and end point H) of the first antenna pattern 115a. The arc-chord ratio of the first antenna pattern 115a is set to be not less than 2. For example, the arc-chord ratio can be 2, 2.5, 3, etc., which can effectively improve the bending degree of the first antenna pattern 115a, thereby effectively improving the space utilization rate of the first antenna pattern 115a. The extended length of the first antenna pattern 115a is the length of the arc GH between the end point G of the starting end 1151a of the first antenna pattern 115a and the end point H of the free end 1152a along the extension direction.

[0134] Alternatively, if Figure 20 to Figure 21As shown, in some embodiments, the first antenna pattern 115a and the second antenna pattern 115b are arranged at intervals, and a grounding point 1154a for grounding is arranged on the second antenna pattern 115b to serve as a parasitic branch of the first antenna pattern 115a. Specifically, the second antenna pattern 115b is connected to the first antenna pattern 115a only by coupling, wherein the feeding point 1151b is arranged on the first antenna pattern 115a and is arranged close to one end point of the first antenna pattern 115a (for example, in some embodiments, the feeding point 1151b is arranged at the end point G of the starting end 1151a of the first antenna pattern 115a), so that the feeding signal is directly transmitted to the first antenna pattern 115a through the feeding point 1151b. Due to the coupling between the first antenna pattern 115a and the second antenna pattern 115b, the feeding signal that originally acts completely on the first antenna pattern 115a can be dispersed to the first antenna pattern 115a and the second antenna pattern 115b respectively by electromagnetic coupling. In other words, after the first antenna pattern 115a and the second antenna pattern 115b are coupled, the current flowing through the antenna pattern 115 due to the excitation of the feeding signal is split into two parts, one part of the current acts on the first antenna pattern 115a, and the other part of the current acts on the second antenna pattern 115b, thereby effectively preventing the current generated based on the feeding signal from being completely concentrated on the first antenna pattern 115a or the second antenna pattern 115b, thereby dispersing the energy hotspots on the antenna pattern 115, and further reducing the SAR value of the antenna pattern 115. Preferably, in some embodiments, the grounding point 1154a is set as far away from the feeding point 1151b as possible, so that the current can be further dispersed, thereby further dispersing the energy hotspots on the antenna pattern 115, and further reducing the SAR value of the antenna pattern 115.

[0135] Preferably, if Figure 20 to Figure 21 As shown, in some embodiments, when the second antenna pattern 115b serves as a parasitic branch of the first antenna pattern 115a, the length of the first antenna pattern 115a (i.e., the arc length of the arc GH along the extension direction of the first antenna pattern 115a) and the length of the second antenna pattern 115b (i.e., the extension length of the second antenna pattern 115b) can be set to be the same, and the length of the first antenna pattern 115a is equal to one quarter of the wavelength of the feeding signal. With this setting, the overall length of the antenna pattern 115 is half the wavelength of the feeding signal, thereby effectively improving the antenna function stability of the antenna pattern 115.

[0136] Alternatively, if Figure 20 to Figure 21As shown, in some embodiments, the second antenna pattern 115b is at least partially arranged in a wave shape, so that the length of the second antenna pattern 115b can be effectively extended within a limited space, and the space utilization rate of the second antenna pattern 115b can be effectively improved. Fig.21 As shown, in some embodiments, the second antenna pattern 115b can also be arranged in a shape of a plurality of “J”-shaped bends connected.

[0137] Alternatively, if Figure 20 to Figure 21 As shown, in some embodiments, the second antenna pattern 115b is at least partially located inside the first semi-closed structure. This configuration allows the second antenna pattern 115b to effectively utilize the area enclosed by the first semi-closed structure, thereby making the second antenna pattern 115b and the first antenna pattern 115a more compact, effectively improving the space utilization of the antenna pattern 115.

[0138] Preferably, in some embodiments, the first antenna pattern 115a includes a first pattern portion 1151 and a second pattern portion 1152 arranged side by side and a third pattern portion 1153 connecting the first pattern portion 1151 and the second pattern portion 1152, so that the first pattern portion 1151, the second pattern portion 1152 and the third pattern portion 1153 are surrounded to form a first semi-enclosed structure. In this embodiment, the first semi-enclosed structure is arranged in a "U" shape. In some embodiments, the first semi-enclosed structure can be a semi-enclosed curved arc structure such as a "C" shape or a "V" shape. Furthermore, in some embodiments, the second antenna pattern 115b is at least partially disposed between the first pattern portion 1151 and the second pattern portion 1152, and the projection of the second antenna pattern 115b along the direction opposite to the opening direction of the first antenna pattern 115a at least partially overlaps with the third pattern portion 1153. In other words, a portion of the second antenna pattern 115b is inserted into the interior of the first semi-closed structure, and the other portion passes through and extends along the opening of the first semi-closed structure (i.e., the first opening 115c), thereby making the second antenna pattern 115b and the first antenna pattern 115a more compact, thereby effectively improving the space utilization of the antenna pattern 115.

[0139] Alternatively, if Fig. 20As shown, in some embodiments, at least part of the second antenna pattern 115b can be reused for detecting touch signals, which can effectively simplify the structure of the earphone 10 and effectively improve the assembly efficiency of the earphone 10. Preferably, in some embodiments, the second antenna pattern 115b includes a main body 1154 arranged in a block shape and an extension 1155 connected to the main body 1154 and arranged in a wave shape. Specifically, the main body 1154 is reused as the touch pattern 116 of the earphone 10 to receive the touch signal. At the same time, the extension 1155 extends the length of the main body 1154 to cooperate with the main body 1154 to help the second antenna pattern 115b form an antenna pattern of sufficient length to disperse the current of the first antenna pattern 115a. Further, in some embodiments, the extension 1155 can also be reused as a component for receiving touch signals, effectively extending the touch area of ​​the main body 1154, thereby effectively improving the touch comfort of the earphone 10. In some embodiments, the extension 1155 can also be an inductor.

[0140] Preferably, in some embodiments, the headset 10 is also provided with a grounding circuit including at least a capacitor, and the first signal end of the capacitor is connected to the grounding point 1154a, and the second signal end of the capacitor is grounded. Such a configuration enables, when at least part of the second antenna pattern 115b is reused for detecting a touch signal, mutual interference between the touch signal and the Bluetooth signal is effectively prevented.

[0141] Alternatively, if Fig. 22As shown, in some embodiments, the second antenna pattern 115b is connected to the first antenna pattern 115a with the feeding point 1151b as a dividing point, and the feeding point 1151b is configured to provide a feeding signal to the first antenna pattern 115a and the second antenna pattern 115b respectively. The feeding signal emitted by the feeding point 1151b is divided into two parts, and flows to the first antenna pattern 115a and the second antenna pattern 115b respectively, effectively dispersing the current to the first antenna pattern 115a and the second antenna pattern 115b respectively, so as to effectively reduce the current intensity loaded on the first antenna pattern 115a and the second antenna pattern 115b, thereby effectively reducing the SAR value of the antenna pattern 115. At the same time, the first antenna pattern 115a and the second antenna pattern 115b are coupled, and the resultant current formed by the feeding signal on the first antenna pattern 115a and the resultant current formed by the feeding signal on the second antenna pattern 115b are in a mutually inhibiting relationship. Based on this, the magnetic field formed by the resultant current on the first antenna pattern 115a and the magnetic field formed by the resultant current on the second antenna pattern 115b weaken each other, thereby effectively reducing the magnetic field strength of the resultant magnetic field of the antenna pattern 115 (that is, the magnetic field formed by the combined electric field on the first antenna pattern 115a and the magnetic field formed by the combined current on the second antenna pattern 115b), thereby reducing the proportion of the normal component of the resultant magnetic field entering the user's head, thereby reducing the human body's absorption rate of the resultant magnetic field, thereby effectively reducing the SAR value of the antenna pattern 115.

[0142] Alternatively, if Fig. 22As shown, in some embodiments, the second antenna pattern 115b is bent along its extension direction (wherein the extension direction of the second antenna pattern 115b is defined with reference to the extension direction of the first antenna pattern 115a) to form a second semi-closed structure with a second opening 115d, so that the second antenna pattern 115b is arranged in an arc shape as a whole. Such arrangement, on the one hand, can effectively improve the space utilization rate of the second antenna pattern 115b, and on the other hand, can also make the current flow direction on the second antenna pattern 115b as a whole arc-shaped, so as to correspond to the arc-shaped current flow direction on the first antenna pattern 115a (the first antenna pattern 115a is bent along its extension direction as described above), so as to be more conducive to forming electromagnetic fields with a mutually inhibiting relationship. Further, in some embodiments, the projection of the first antenna pattern 115a in the opposite direction of the opening direction of the second antenna pattern 115b (i.e., the second opening direction X4) at least partially overlaps with the second antenna pattern 115b, so that the first antenna pattern 115a and the second antenna pattern 115b have overlapping parts in the first opening direction X3 or the second opening direction X4, that is, the first antenna pattern 115a and the second antenna pattern have relatively arranged parts along the first opening direction X3 or the second opening direction X4, and because the currents on the first antenna pattern 115a and the second antenna pattern 115b flow into or out of the feeding point 1151b at the same time, the electromagnetic fields formed by the first antenna pattern 115a and the second antenna pattern 115b at least in the relatively arranged parts along the first opening direction X3 or the second opening direction X4 have a mutual inhibition relationship, thereby effectively reducing the magnetic field strength of the combined magnetic field of the antenna pattern 115, and thereby reducing the proportion of the normal component of the combined magnetic field entering the user's head, so as to reduce the absorption rate of the human body to the combined magnetic field, thereby effectively reducing the SAR value of the antenna pattern 115.

[0143] Specifically, see Fig. 22 The second antenna pattern 115b has a starting end 1156b (the starting end 1156b has an end point K) and a free end 1156a (the free end 1156a has an end point S), and extends from the end point K of the starting end 1156b to the end point S of the free end 1156a, thereby forming an extension direction of the second antenna pattern 115b. Specifically, the second opening direction X4 is defined as, when viewed along the direction toward the main surface of the second antenna pattern 115b, the line connecting the end point K of the starting end 1156b of the second antenna pattern 115b and the end point S of the free end 1156a forms a line segment KS, and the direction perpendicular to the line segment KS and pointing to the outside of the second semi-closed structure is the second opening direction X4.

[0144] Alternatively, if Fig. 22As shown, in some embodiments, in an area near the feeding point 1151b, the first antenna pattern 115a and the second antenna pattern 115b are arranged to extend away from each other with the feeding point 1151b as a starting point, so that in the area near the feeding point 1151b, the first antenna pattern 115a and the second antenna pattern 115b are relatively arranged, so that in the area near the feeding point 1151b, the electromagnetic field formed on the first antenna pattern 115a and the electromagnetic field on the second antenna pattern 115b have a mutual inhibition relationship, further reducing the magnetic field strength of the combined magnetic field of the antenna pattern 115, and thus reducing the proportion of the normal component of the combined magnetic field entering the user's head, so as to reduce the human body's absorption rate of the combined magnetic field, thereby effectively reducing the SAR value of the antenna pattern 115.

[0145] Alternatively, if Fig. 22 As shown, in some embodiments, the free end 1152a of the first antenna pattern 115a and the free end 1156a of the second antenna pattern 115b are arranged adjacent to each other, and in the area near the free end 1152a of the first antenna pattern 115a and the free end 1156a of the second antenna pattern 115b, the first antenna pattern 115a and the second antenna pattern 115b are arranged to extend close to each other with their respective free ends as end points, so that the second opening 115d of the second antenna pattern 115b is arranged opposite to the first opening 115c of the first antenna pattern 115a, so that the combined electromagnetic field (wherein the electromagnetic field is a general term for the magnetic field and the electric field) that can be formed on the first antenna pattern 115a is arranged differently from the combined electromagnetic field formed on the second antenna pattern 115b, thereby effectively reducing the proportion of the normal component of the combined magnetic field finally formed in the area near the antenna pattern 115 entering the user's head, so as to reduce the absorption rate of the human body to the combined magnetic field, and then effectively reduce the SAR value of the antenna pattern 115.

[0146] Preferably, if Fig. 22 As shown, in some embodiments, the spacing distance between the free end 1152a of the first antenna pattern 115a and the free end 1156a of the second antenna pattern 115b is smaller than the opening width of the first antenna pattern 115a and also smaller than the opening width of the second antenna pattern 115b. Such a configuration can effectively improve the overall space utilization of the antenna pattern 115. Specifically, the opening width of the first antenna pattern 115a is defined as the length of the line segment GH between the end point G of the starting end 1151a and the free end 1152a. The spacing distance between the free end 1152a of the first antenna pattern 115a and the free end 1156a of the second antenna pattern 115b is defined as the length of the line segment GS between the end point G of the free end 1152a and the end point S of the free end 1156a.

[0147] Furthermore, in some embodiments, the main plane of the first antenna pattern 115a and the main plane of the second antenna pattern 115b are arranged parallel to or coplanar with each other, based on which the mutual inhibition relationship between the electromagnetic field formed on the first antenna pattern 115a and the electromagnetic field on the second antenna pattern 115b can be further increased, thereby further reducing the proportion of the normal component of the combined magnetic field formed in the vicinity of the antenna pattern 115 that enters the user's head, thereby reducing the human body's absorption rate of the combined magnetic field, and thereby effectively reducing the SAR value of the antenna pattern 115.

[0148] Alternatively, if Fig. 22 As shown, in some embodiments, the arc-chord ratio of the second antenna pattern 115b is not less than 2. Specifically, the second antenna pattern 115b is arranged in an arc shape as a whole, and the length of the second antenna pattern 115b is the length of the arc KS between the end point K of the starting end 1156b of the second antenna pattern 115b and the end point S of the free end 1156a along the extension direction. The arc-chord ratio of the second antenna pattern 115b is the ratio of the length of the arc KS to the length of the line segment KS. Among them, the arc-chord ratio of the second antenna pattern 115b is set to be not less than 2, for example, the arc-chord ratio can be 2, 2.5, 3 and other actual values, which can effectively improve the bending degree of the second antenna pattern 115b, thereby effectively reducing the space occupancy rate of the second antenna pattern 115b. Optionally, in this embodiment, the second semi-enclosed structure is arranged in a "U" shape. In some embodiments, the second semi-enclosed structure can be a semi-enclosed curved arc structure such as a "C" shape or a "V" shape.

[0149] Optionally, in some embodiments, the earphone 10 also includes a touch pattern 116 independent of the antenna pattern 115, and the touch pattern 116 is at least partially disposed in the first semi-enclosed structure and / or the second semi-enclosed structure. This can effectively improve the space utilization of the touch pattern 116 and the antenna pattern 115, thereby effectively reducing the space occupancy of the touch pattern 116 and the antenna pattern 115.

[0150] Optionally, in some embodiments, the antenna pattern 115 is disposed on a side of the second housing 1102 away from the first housing 1101 , so that the clearance height of the antenna pattern 115 can be maximized to improve the performance of the antenna pattern 115 .

[0151] Furthermore, in some embodiments, the main control circuit board 112 and the speaker 111 are stacked in the accommodating space 1103 along the thickness direction X, and the main control circuit board 112 is arranged close to the second shell 1102 relative to the speaker 111 along the thickness direction X. The main control circuit board 112 is provided with a radio frequency circuit connected to the feeding point 1151b and used to output a feeding signal. Based on this arrangement, the distance between the antenna pattern 115 and the main control circuit board 112 can be effectively reduced, thereby effectively shortening the routing between the main control circuit board 112 and the antenna pattern 115, so as to improve the space utilization rate of the shell assembly 110.

Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
