Description

An air-conducting loudspeaker and headphones [Technical Field]

[0001] This application relates to the technical field of electronic devices, specifically to an air-conducting speaker and headphones. [Background Technology]

[0002] With the increasing prevalence of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's demands for these devices are also rising. Headphones and smart glasses, for example, are widely used in daily life, working in conjunction with mobile phones, computers, and other terminal devices to provide users with an auditory feast. The size of headphones greatly affects the user experience; therefore, the air-conducting speaker, as a crucial component for headphone sound production, should not only maintain good sound quality but also have a small structural size to meet the miniaturization requirements of headphones. However, traditional air-conducting speaker designs cannot effectively address the problem of degraded sound quality caused by the reduction in the size of the air-conducting speaker.

[0030] In some embodiments, the sound guide seat has an annular flange on one side facing the two sound inlets. The annular flange surrounds and forms a second groove. The annular flange is embedded in the mounting groove and presses and fixes the acoustic barrier mesh onto the annular platform.

[0031] In some embodiments, the sound guide is supported on the bottom of the mounting groove, and the projection of the first groove along the interval direction falls into the second groove.

[0032] In some embodiments, the groove depth of the second groove is set to 0.2 to 0.5 mm.

[0033] In some implementations, the projection of the sound inlet end of the sound guide channel along the spacing direction is at least partially located in the spacing region between the two sound inlets.

[0034] In some embodiments, the sound inlet 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 near the outside of the housing assembly is inclined toward the rear of the human body relative to the sagittal plane, 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°.

[0035] This application provides an earphone, which includes a mechanism module and an ear hook connected to the mechanism module. In the wearing state, the mechanism module is located on the front side of the ear, and at least a portion of the ear hook is hung on the back side of the ear. The ear hook includes an elastic connector, a housing, and an elastic cover. One end of the elastic connector is connected to the mechanism module, and the other end is connected to the housing. The elastic cover includes a first cover section and a second cover section. At least a portion of the first cover section is molded to cover the periphery of the elastic connector, and at least a portion of the second cover section is fitted to cover at least a portion of the periphery of the housing away from the elastic connector.

[0036] In some embodiments, the housing includes a first housing covered by a second covering section and a boss disposed at the end of the first housing away from the elastic connector. The second covering section is bag-shaped and has an opening at the free end away from the elastic connector for the first housing to be inserted into the second covering section. The opening surrounds the periphery of the side wall of the boss.

[0037] In some embodiments, the ratio of the radial dimension of the boss to the maximum radial dimension of the first housing is between 0.4 and 0.7.

[0038] In some embodiments, the edge of the opening contacts the side wall of the boss, or the gap between the edge of the opening and the side wall of the boss is less than 0.2 mm.

[0039] In some embodiments, both the opening and the boss are circular when viewed from the direction of the outer end face of the boss.

[0040] In some embodiments, when viewed from the outer end face of the boss, the first housing is circular, and the center of the first housing is concentric with the center of the boss, or the distance between the center of the first housing and the center of the boss is less than 5 mm.

[0041] In some embodiments, the outer surface of the free end of the first housing is provided in a tapered shape with an arc transition in the direction away from the elastic connector.

[0042] In some embodiments, the outer surface of the free end of the first housing is spherically shaped.

[0043] In some embodiments, at the boss position, the outer surface of the second covering section is flush with the outer end face of the boss, or the outer end face of the boss protrudes beyond the outer surface of the second covering section, and the protrusion height is not greater than 3mm.

[0044] In some embodiments, the housing further includes a second housing, one end of which is connected to the other end of the elastic connector, and the other end is connected to the end of the first housing opposite to the boss, to form a housing, and the first covering section further covers the periphery of the second housing in a molded manner.

[0045] In some embodiments, the second housing includes a main body and an insertion part. The main body is connected to an elastic connector, and the insertion part is connected to the end of the main body facing the receiving housing. The radial dimension of the insertion part is smaller than the radial dimension of the main body, thereby forming an annular platform at the connection between the insertion part and the main body. The receiving housing has an open end, and the insertion part is inserted into the receiving housing from the open end. The open end further abuts against the annular platform. At the open end position, the outer surface of the receiving housing smoothly transitions with the outer surface of the main body.

[0046] In some embodiments, the earphones also include adhesive that is at least filled between the outer surface of the first housing and the second covering section, with the adhesive spaced apart from the peripheral sidewall of the boss.

[0047] In some embodiments, the second covering segment is attached to the outer wall of the first housing.

[0048] In some embodiments, under natural conditions, the radial dimension of the enclosing space formed by the second enclosing segment is smaller than the radial dimension of the first shell.

[0049] This application provides an earphone, which includes an antenna pattern, comprising a first antenna pattern and a second antenna pattern. The first antenna pattern has a feed point for receiving a feed signal. The first antenna pattern is bent along its extension direction to form a first semi-closed structure with a first opening. The second antenna pattern is coupled to the first antenna pattern to disperse the current on the first antenna pattern. When viewed along the direction toward the main surface of the first antenna pattern, the projection of the second antenna pattern in the opposite direction of the opening direction of the first antenna pattern at least partially coincides with the first antenna pattern.

[0050] In some implementations, the arc-to-chord ratio of the first antenna pattern is not less than 2.

[0051] In some embodiments, the first antenna pattern and the second antenna pattern are spaced apart, and the second antenna pattern has a grounding point for grounding, serving as a parasitic branch of the first antenna pattern.

[0052] In some implementations, the second line pattern is at least partially wavy.

[0053] In some implementations, the second antenna pattern is at least partially located inside the semi-enclosed structure.

[0054] In some embodiments, the first antenna pattern includes a first pattern portion and a second pattern portion arranged side by side, and a third pattern portion connecting the first pattern portion and the second pattern portion. The second antenna pattern is at least partially disposed between the first pattern portion and the second pattern portion, and the projection of the second antenna pattern in the opposite direction of the opening direction of the first antenna pattern at least partially overlaps with the third pattern portion.

[0055] In some implementations, the second antenna pattern is at least partially used as a touch pattern for detecting touch signals.

[0056] In some embodiments, the second antenna pattern includes a main body portion arranged in a block shape and an extension portion connected to the main body portion and arranged in a wavy shape.

[0057] In some implementations, the second antenna pattern is connected to the first antenna pattern at a feed point, which is configured to simultaneously provide feed signals to both the first antenna pattern and the second antenna pattern.

[0058] In some embodiments, the second antenna pattern is bent along its extension direction to form a second semi-closed structure with a second opening, and the projection of the first antenna pattern in the opposite direction of the opening of the second antenna pattern at least partially overlaps with the second antenna pattern.

[0059] In some implementations, in the region near the feed point, the first antenna pattern and the second antenna pattern are arranged to extend away from each other from the feed point.

[0060] In some embodiments, the free ends of the first antenna pattern and the free ends of the second antenna pattern are arranged adjacent to each other. In the region near the free ends of the first antenna pattern and the second antenna pattern, the first antenna pattern and the second antenna pattern are arranged to extend close to each other with their respective free ends as endpoints.

[0061] In some embodiments, the spacing between the free ends of the first antenna pattern and the free ends of the second antenna pattern is smaller than the opening width of the first antenna pattern and the opening width of the second antenna pattern.

[0062] In some implementations, the arc-to-chord ratio of the second line pattern is not less than 2.

[0063] In some embodiments, the headphones also include a touch pattern, which is at least partially disposed on the first semi-closed structure and / or the second semi-closed structure.

[0064] The beneficial effects of this application are as follows: The air-conducting loudspeaker includes a diaphragm, a fixing ring, and a frame. The diaphragm includes a vibrating body and an annular fixing part connected to the vibrating body and surrounding the vibrating body. The fixing ring is connected and fixed to the annular fixing part and is fitted onto the frame. The annular fixing part and the fixing ring have a first connection length along the axial direction of the air-conducting loudspeaker and a second connection length along the radial direction of the air-conducting loudspeaker. The first connection length is greater than the second connection length. This arrangement allows the annular fixing part and the fixing ring to be connected primarily by a lateral connection and secondarily by a radial connection. This ensures the connection stability between the annular fixing part and the fixing ring while effectively reducing the radial dimension of the fixing ring, thereby effectively reducing the radial dimension of the loudspeaker and thus effectively reducing the overall volume of the loudspeaker. Furthermore, as the main component that vibrates and produces sound, the radial dimension of the diaphragm, especially the radial dimension of the vibrating body, directly affects the sound quality of the speaker. Generally, the larger the radial dimension of the vibrating body, the better the sound quality of the speaker. Therefore, the annular fixing part and the fixing ring are mainly connected by a lateral connection method. This allows the radial dimension of the vibrating body of the diaphragm to be made larger while ensuring the connection stability between the annular fixing part and the fixing ring (which can also be understood as the speaker being able to be equipped with a diaphragm with a larger radial dimension). This effectively improves the sound quality of the speaker while also effectively reducing the overall size of the speaker. [Attached Image Description]

Detailed Implementation Methods

[0088] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0089] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0090] Referring to Figure 1, the user's ear 100 may include physiological parts such as the external auditory canal 101, the concha 102, the cymba conchae 103, the triangular fossa 104, the antihelix 105, the scaphoid fossa 106, the helix 107, and the antitragus 108. While the external auditory canal 101 has a certain depth and extends to the tympanic membrane, for ease of description and in conjunction with Figure 1, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance (i.e., the ear canal) away from the tympanic membrane. Furthermore, the physiological parts such as the concha 102, the cymba conchae 103, and the triangular fossa 104 have a certain volume and depth; and the concha 102 is directly connected to the external auditory canal 101, meaning the aforementioned ear canal can be simply considered as being located at the bottom of the concha 102.

[0091] Furthermore, individual differences may exist among different users, resulting in variations in ear shape, size, and other dimensional differences. To facilitate description and reduce (or even eliminate) these individual differences, a simulator containing the head and its (left and right) ears can be manufactured based on ANSI:S3.36, S3.25 and IEC:60318-7 standards. Examples include the GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, to represent the scenario of most users wearing headphones 10. Taking the GRAS KEMAR as an example, the ear simulator can be any one of the GRAS 45AC, GRAS 45BC, GRAS 45CC, or GRAS 43AG; taking HEAD Acoustics as an example, the ear simulator can be any one of the HMS II.3, HMS II.3LN, or HMS II.3LN HEC. Therefore, in this application, descriptions such as "the user is wearing the earphone 10," "the earphone 10 is in a wearing state," and "in a wearing state" can refer to the earphone 10 being worn on the ears of the aforementioned simulator. Of course, due to individual differences among users, the earphone 10 may differ from the earphone 10 being worn on the ears of the aforementioned simulator when worn by different users, but such differences should be tolerable.

[0092] It should be noted that in medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the left-right direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left-right direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical 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 "back side of the ear." The former refers to the side of the ear that is away from the head, while the latter refers to the side of the ear that faces the head. Both refer to the user's ear. Specifically, by observing the ear of the simulator along the direction of the human coronal axis, a schematic diagram of the front contour of the ear shown in Figure 1 can be obtained.

[0093] As an example, referring to Figures 2 to 4, the earphone 10 may include a mechanism module 11 and an ear hook portion 12 connected to the mechanism module 11. The mechanism module 11 is located on the front side of the ear when worn, and at least part of the ear hook portion 12 is located on the back side of the ear when worn, so that the earphone 10 is hung on the ear when worn. The mechanism module 11 may have a connection end CE connected to the ear hook portion 12 and a free end FE not connected to the ear hook portion 12. Furthermore, the mechanism module 11 may be configured not to block the external auditory canal when worn, making the earphone 10 an "open-back earphone". Due to individual differences among users, when the earphone 10 is worn by different users, the mechanism module 11 may partially cover the external auditory canal, but the external auditory canal will still not be blocked.

[0094] Optionally, in some embodiments, the mechanism module 11 includes a mechanism housing (in some embodiments of this application, the mechanism housing is also referred to as housing assembly 110), a speaker 111, and a main control circuit board 112. The speaker 111 and the main control circuit board 112 are stacked within the mechanism housing, which effectively improves the space utilization of the earphone 10. The speaker 111 is a component that converts electrical signals into corresponding sound signals 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, and it is provided with various control circuits for controlling components of the earphone 10 such as the speaker 111, Bluetooth, and microphone, for example, a main control circuit. In this embodiment, the speaker 111 is an air conduction speaker 111; in other embodiments, the speaker 111 can also be configured as a bone conduction speaker 111.

[0095] Optionally, in some embodiments, the housing assembly 110 includes a first housing 1101 and a second housing 1102 that cooperate with each other, which can effectively improve the assembly efficiency of the earphone 10.

[0096] Optionally, as shown in Figures 5 to 8, in some embodiments, the ear hook portion 12 includes an elastic connector 122 and a housing 124. One end of the elastic connector 122 is connected to the mechanism module 11, and the other end is connected to the housing 124. With this configuration, the elastic connector 122 can provide elastic force to the mechanism module 11 located on the front side of the ear and the housing 124 located on the back side of the ear, so that the elastic connector 122 clamps the front and rear sides of the ear through the housing 124 and the mechanism module 11, thereby effectively improving the wearing stability of the earphone 10.

[0097] Optionally, as shown in Figures 5 to 8, in some embodiments, the ear hook portion 12 further includes an elastic cover 121 covering the periphery of the elastic connector 122 and the housing 124. The elastic cover 121 is a flexible member with elasticity. This arrangement allows the ear hook portion 12 to abut against the ear through the elastic cover 121, thereby effectively improving the wearing comfort of the ear hook portion 12 and thus effectively improving the wearing comfort of the earphone 10.

[0098] Optionally, as shown in Figures 5 to 8, in some embodiments, the housing 124 forms a receiving compartment 1243 for accommodating at least a portion of the internal structural components of the earphone 10, such as a battery. Further, in some embodiments, the elastic cover 121 includes a first covering segment 1211 and a second covering segment 1212. At least a portion of the second covering segment 1212 is fitted over the periphery of at least a portion of the housing 124 away from the elastic connector 122, reducing the risk of damage to the internal structural components when assembling at least a portion of the second covering segment 1212 into this portion of the housing 124 using other assembly processes. This further improves the operational stability of the earphone 10 and effectively reduces the assembly complexity of the ear hook portion 12. Further, in some embodiments, at least a portion of the first covering segment 1211 is molded over the periphery of the elastic connector 122, thus effectively improving the stability of the ear hook portion 12. For example, in some embodiments, at least a portion of the first covering segment 1211 may be covered around the elastic connector 122 by injection molding.

[0099] Specifically, in this embodiment, the first covering section 1211 and the second covering section 1212 are an integrated structure, which effectively reduces the assembly complexity of the ear hook part 12. In other embodiments, the first covering section 1211 and the second covering section 1212 may also be separate structures.

[0100] Optionally, as shown in FIG5, in some embodiments, the accommodating housing 124 includes a first housing 1241 and a second housing 123. One end of the second housing 123 is connected to the other end of the elastic connector 122 (i.e., the free end ZY of the elastic connector 122), and the other end is connected to the first housing 1241 to cooperate with the first housing 1241 to form an 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 rolled up from the opening 1213 end of the second covering section 1212 to expose the connection between the first housing 1241 and the second housing 123, thereby allowing the first housing 1241 to easily cooperate and connect with the second housing 123. After the connection is completed, the second covering segment 1212 is rolled down and fitted onto at least a portion of the outer periphery of the first housing 1241. This arrangement allows the second covering segment 1212 to cover the outer periphery of the first housing 1241 in a fitted manner, thereby effectively improving the working stability of the earphone 10 and reducing the assembly complexity of the ear hook 12. It should be noted that in some embodiments, the second housing 123 may not be provided, and the elastic connector 122 may be directly connected to the first housing 1241, that is, the connection point is located at the free end of the elastic connector 122.

[0101] Preferably, in some embodiments, the housing 124 further includes a boss 1242 disposed at the end of the first housing 1241 away from the free end of the elastic connector 122. The opening 1213 of the second covering section 1212 is disposed around the periphery of the side wall of the boss 1242. This arrangement allows the opening 1213 to form a mating relationship with the boss 1242, thereby effectively improving the connection stability between the elastic covering 121 and the housing 124, reducing the risk of relative movement between the elastic covering 121 and the housing 124. Furthermore, the elastic covering 121 with the opening 1213 can completely cover the periphery of the housing 124 except for the boss 1242, ensuring that when worn, the position where the housing 124 abuts against the head and ears can abut against the head and ears through the elastic covering 121, thereby effectively improving the wearing comfort of the headphones 10. Specifically, in some embodiments, the boss 1242 and the first housing 1241 can be integrally disposed. In other embodiments, the boss 1242 and the first housing 1241 can be separately configured. For example, in some embodiments, the boss 1242 and the first housing 1241 can be assembled by means of assembly.

[0102] Optionally, as shown in Figures 5-8, in some embodiments, the second housing 123 serves as a connector between the elastic connector 122 and the first housing 1241. One end of the second housing 123 is connected to the other end of the elastic connector 122 (i.e., the end of the elastic connector 122 away from the movement module 11). Along the direction of the elastic connector 122 away from the movement module 11, the cross-sectional area of ​​the second housing 123 gradually increases, forming an arc-shaped transition to improve wearing comfort. Preferably, in some embodiments, the first covering segment 1211 is further molded to cover the periphery of the second housing 123. This effectively simplifies the covering process of the first covering segment 1211 and facilitates better attachment of the first covering segment 1211 to the transition area between the elastic connector 122 and the housing 1241.

[0103] Optionally, in some embodiments, the second covering segment 1212 is attached to the outer wall of the first housing 1241. This arrangement can effectively improve the connection stability between the second covering segment 1212 and the first housing 1241. For example, in some embodiments, in the natural state (i.e., before being fitted onto the first housing 1241), the radial dimension of the covering space formed by the second covering segment 1212 is smaller than the radial dimension of the first housing 1241. With this arrangement, when the second covering segment 1212 is fitted onto the first housing 1241, the first housing 1241 supports the second covering segment 1212 from within, thereby causing the second covering segment 1212 to have a tendency to elastically contract towards the first housing 1241, thus attaching to the outer wall of the first housing 1241, thereby effectively improving the connection stability between the second covering segment 1212 and the first housing 1241. Furthermore, in some embodiments, in the natural state (i.e. before being fitted onto the first housing 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 setting, when the second covering segment 1212 is fitted onto the first housing 1241, the edge of the opening 1213 tends to elastically contract toward the boss 1242, further improving the connection stability between the second covering segment 1212 and the first housing 1241.

[0104] Optionally, as shown in Figure 7, in some embodiments, the edge of the opening 1213 contacts the sidewall of the boss 1242, or the gap J1 between the edge of the opening 1213 and the sidewall of the boss 1242 is less than 0.2 mm. This configuration effectively prevents dust, sweat, and other impurities from seeping into the space between the second covering section 1212 and the housing 124 along the gap between the edge of the first housing 1241 and the sidewall of the boss 1242, thus preventing bulging of the ear loop portion 12. Furthermore, when the radial dimension of the boss 1242 remains constant, the smaller the gap J1, the larger the area where the bottom of the second covering section 1212 abuts against the first housing 1241 along the axial direction z1 of the housing 124, effectively reducing the risk of the second covering section 1212 detaching from the housing 124.

[0105] Referring further to Figure 7, the boss 1242 is the part on the housing 124 that mates with the first housing 1241. The larger the radial dimension d1 of the boss 1242, the larger the radial dimension of the first housing 1241 will be after the second covering section 1212 covers the periphery of the housing 124. This will result in the second covering section 1212 lacking a sufficiently large area at the bottom along the axial direction z1 of the housing 124 to abut against the first housing 1241, thereby increasing the risk of the second covering section 1212 detaching from the housing 124. Therefore, in some embodiments, the radial dimension d1 of the boss 1242 is smaller than the maximum radial dimension d2 of the first housing 1241. This arrangement can effectively ensure that the bottom of the first housing 1241 (the bottom of the first housing 1241 is the bottom away from the second housing 123 along the axial direction z1 of the first housing 1241) is not completely occupied by the boss 1242, so that the bottom of the first housing 1241 has a sufficiently large area to abut against the second covering section 1212, effectively reducing the risk of the second covering section 1212 detaching from the housing 124.

[0106] Optionally, as shown in FIG7, in some embodiments, the ratio of the radial dimension d1 of the boss 1242 to the maximum radial dimension d2 of the first housing 1241 is between 0.4 and 0.7. This setting can further ensure that the bottom of the first housing 1241 has a sufficiently large area to abut against the second covering section 1212, thereby further reducing the risk of the second covering section 1212 detaching from the housing 124, while avoiding the difficulty of fitting due to the opening 1213 being too small.

[0107] Optionally, in some embodiments, when viewed from the direction X1 toward the outer end face of the boss 1242, the first housing 1241 and the boss 1242 are arranged in a circular shape. This arrangement makes the contour of the edge of the first housing 1241 and the contour of the side wall of the boss 1242 smoother, reducing the risk of tearing when the second covering section 1212 is fitted onto the first housing 1241, thereby effectively improving the structural strength of the second covering section 1212. Furthermore, setting the boss 1242 in a circular shape effectively improves the aesthetics of the ear loop portion 12 while reducing the molding complexity of the housing 124 and the second covering section 1212.

[0108] It is worth noting that in some embodiments, the direction X1 toward the outer end face of the boss 1242 is parallel to the axial direction z1 of the first housing 1241, and the mating direction of the first housing 1241 and the second housing 123 is parallel to the axial direction z1 of the accommodating housing 124.

[0109] Optionally, in some implementations, when viewed from the direction of the outer end of the boss 1242, the first housing 1241 is circular, that is, along the axial direction z1 of the first housing 1241, the outline of the first housing 1241 is circular (it should be noted that the circle referred to here can be understood as an ellipse or a circular or similar structure). For example, the first housing 1241 is cylindrical in shape. This arrangement makes the outer side of the first housing 1241 have a smooth arc surface, so that the second covering section 1212 can contact the user's head and ears with a smooth arc surface, thereby effectively improving the wearing comfort of the headphones 10. Furthermore, the center of the first housing 1241 (that is, the center of the circular outline of the first housing 1241 along the axial direction z1) and the center of the boss 1242 (that is, the center of the boss 1242 along the axial direction z1 of the first housing 1241 and the center of the circular outline of the boss 1242) are concentrically arranged, or the distance between the center of the first housing 1241 and the center of the boss 1242 is less than 5mm. Since the relative position of the center of the first housing 1241 and the center of the boss 1242 directly affects their relative positional relationship, the first housing 1241 should be coaxially aligned with the boss 1242 as much as possible. This ensures that the resultant elastic force of the elastic force exerted by the second covering segment 1212 on the first housing 1241 is as parallel as possible to the axial direction z1 of the first housing 1241, preventing the resultant elastic force from affecting the fit stability between the first housing 1241 and the second housing 123, and effectively reducing the risk of the second covering segment 1212 detaching from the first housing 1241. Therefore, setting the center of the first housing 1241 and the center of the boss 1242 concentrically, or ensuring that the distance between the center of the first housing 1241 and the center of the boss 1242 is less than 5mm, can effectively improve the connection stability between the first housing 1241 and the second housing 123, while also effectively reducing the risk of the second covering segment 1212 detaching from the first housing 1241.

[0110] Furthermore, in some embodiments, when worn, the axial direction z1 of the first housing 1241 is arranged parallel to the sagittal plane, and the center of the protrusion 1242 is set to be concentric with the center of the first housing 1241, which can effectively prevent the protrusion 1242 from contacting the user's head and ears, thereby effectively improving the wearing comfort of the earphone 10.

[0111] Optionally, as shown in Figures 5 and 6, in some embodiments, the outer surface of the free end of the first housing 1241 has a gradually tapering arc-shaped transition in the direction away from the second housing 123 (that is, the axial direction z1 of the first housing 1241 and the positive direction away from the second housing 123). This configuration makes the outer surface of the bottom of the first housing 1241 arc-shaped, which can effectively improve the wearing comfort and aesthetics of the ear hook 12 to a certain extent, without affecting the connection stability between the second covering section 1212 and the first housing 1241.

[0112] Optionally, as shown in Figures 5 and 6, in some embodiments, the outer surface of the free end of the first housing 1241 is spherically shaped, which can effectively improve the aesthetics and wearing comfort of the ear hook 12.

[0113] Optionally, as shown in FIG8, 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 face of the boss 1242, or the outer end face of the boss 1242 protrudes from the outer surface of the second covering section 1212, and the protrusion height g1 is not greater than 3mm. Specifically, the boss 1242 is the part that accommodates the housing 124 exposed in the second covering section 1212. Therefore, setting the outer surface of the second covering section 1212 at the position of the boss 1242 to be flush with the outer end face of the boss 1242, or setting the outer end face of the boss 1242 to protrude from the outer surface of the second covering section 1212, and setting the protrusion height g1 to be not greater than 3mm, can effectively improve the integrity of the ear hook 12, thereby improving the aesthetics of the earphone 10, and can also effectively reduce the risk of the boss 1242 contacting the ear and 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 absolutely flush with the outer end face of the boss 1242. Therefore, in some embodiments, considering the above limitations, the outer surface of the second covering section 1212 and the outer end face of the boss 1242 can have a height difference, and the absolute value of the height difference is within 0.01mm. This setting can make the outer surface of the second covering section 1212 and the outer end face of the boss 1242 almost flush, thereby effectively improving the aesthetics of the earphone 10.

[0114] As shown in Figures 7 and 8, in some embodiments, the second housing 123 includes a main body 1232 and an insertion part 1231. The main body 1232 is connected to the elastic connector 122, and the insertion part 1231 is connected to the end of the main body 1232 facing the receiving housing 124. The radial dimension of the insertion part 1231 is smaller than the radial dimension of the main body 1232, thereby forming an annular platform at the connection between the insertion part 1231 and the main body 1232. The receiving housing 124 has an open end 1244. The insertion part 1231 is inserted into the receiving housing 124 from the open end 1244, and the open end 1244 further abuts against the annular platform. At the position of the open end 1244, the outer surface of the receiving housing 124 smoothly transitions with the outer surface of the main body 1232. This arrangement makes the outer surface of the elastic cover 121 present a smooth transition and a smooth contour, effectively improving the wearing comfort of the earphone 10. The above method can also effectively reduce the maximum radial dimension of the ear hook 12, thereby effectively improving and reducing the overall structural size of the earphone 10.

[0115] Optionally, in some embodiments, the earphone 10 further includes adhesive that is at least filled between the outer surface of the first housing 1241 and the second covering section 1212. The adhesive is spaced apart from the peripheral sidewall of the boss 1242. This arrangement allows the first housing 1241 and the second covering section 1212 to be connected by adhesive, effectively improving the connection stability between the first housing 1241 and the second covering section 1212, thereby effectively preventing the first housing 1241 and the second covering section 1212 from detaching.

[0116] Optionally, in this embodiment, as shown in Figures 7 and 8, the first housing 1241 serves as the main body of the housing 124 and is used to form the accommodating compartment 1243. The second housing 123 serves as a connector connecting the first housing 2141 and the elastic connector 122, and also as a cover for the first housing 1241. With this configuration, during assembly, components such as batteries that are placed in the accommodating compartment 1243 can be pre-placed in the first housing 1241, and then the first housing 1241 and the second housing 123 can be docked, thereby effectively improving the assembly efficiency of components such as batteries.

[0117] Optionally, in some embodiments, the second housing 123 can serve as the main body of the housing 124. That is, the second housing 123 includes a connecting body (e.g., the main body 1232 in the above embodiment) connected to the elastic connector 122, and also includes a receiving body connected to the connecting housing and used to form a receiving compartment 1243 with an opening at one end. Further, the first housing 1241 serves as an end cap of the second housing 123, covering the open end of the second housing 123 where the receiving compartment 1243 is located, to seal the receiving compartment 1243. The open end of the second housing 123 is located at the end of the second housing 123 away from the elastic connector 122. This makes the overall length of the first housing 1241 along the axial direction z1 smaller than the overall length of the second housing 123 along the axial direction z1. During assembly, this effectively reduces the difficulty of fitting the second covering end 1212 onto the first housing 1241, thereby effectively improving the assembly efficiency and ease of assembly of the first housing 1241 and the second housing 123.

[0118] Optionally, as shown in Figures 4, 9, 10, and 11, in some embodiments, the earphone 10 further includes a microphone assembly 113. A receiving space 1103 is provided inside the housing assembly 110, and the microphone assembly 113 is disposed within the receiving space 1103. Two sound inlets 1135 are provided on the housing assembly 110, connecting the receiving space 1103 and the outside of the housing assembly 110. The sound inlets of the two sound inlets 1135 are spaced apart from each other, corresponding to the area within the receiving space 1103 of the housing assembly 110. The surface is provided with a mounting groove 1142, and the sound output ends of the two sound inlets 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 inlet end of the sound guide channel 1136 is connected to the sound output ends of the two sound inlets 1135 in the mounting groove 1142. The microphone 1131 is configured to receive the sound output from the sound output end of the sound guide channel 1136.

[0119] Specifically, the sound inlet end of the sound inlet 1135 can refer to the end where external sound enters the sound inlet 1135, that is, the end connected to the outside world. The sound outlet end of the sound inlet 1135 can refer to the end where external sound enters the sound guiding channel 1136 after passing through the sound inlet 1135. The sound inlet end of the sound guiding channel 1136 refers to the end where external sound exiting through the sound outlet end of the sound inlet 1135 enters the sound guiding channel 1136. Correspondingly, the sound outlet end of the sound guiding channel 1136 refers to the end where external sound exits the sound guiding channel 1136 after passing through the sound guiding channel 1136. The path from the sound inlet end of the sound inlet 1135 to the sound outlet end of the sound guiding channel 1136 can be called the sound guiding path. Optionally, in some embodiments, the sound guiding channel 1136 can be configured as a straight-through type, a curved type, a multi-layer surround type, or other channel structure forms.

[0120] Preferably, in some embodiments, the housing assembly 110 is provided with two sound inlets 1135. External sound can flow into the sound guide channel 1136 through the two sound inlets 1135 and be transmitted to the microphone 1131, thus effectively improving the sound pickup effect of the microphone 1131. In addition, during the sound pickup process, there may be a large airflow entering the sound inlets 1135. The airflow can enter into the housing assembly 110 through one sound inlet 1135 and flow out through the other sound inlet 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. This can reduce wind noise during sound pickup and thus effectively improve the sound pickup effect of the microphone 1131.

[0121] Furthermore, in some embodiments, the inlet hole 1135 includes an extended channel connecting the inlet end and the outlet end of the inlet hole. In the wearing state, at least a portion of the extended channel near the exterior of the housing assembly 110 is inclined towards the rear of the human body relative to the sagittal plane, and the angle between the extension direction of the extended channel and the sagittal plane is greater than or equal to 5° and less than or equal to 40°. This arrangement ensures that when the headphones are worn, the extended channel of the inlet hole 1135 extends inclined towards the back of the ear, thereby reducing the impact of airflow and further improving sound pickup.

[0122] Furthermore, in some embodiments, the mounting groove 1142 disposed inside the housing assembly 110 can provide a better positioning effect for the sound guide 1132 when it is installed, thereby effectively improving the installation accuracy and assembly efficiency of the sound guide 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. This allows for the formation of a better closed area between the end of the sound guide seat 1132 where the sound guide channel 1136 is located and the end of the two sound inlets 1135, effectively improving the airtightness of the sound guide path. This not only effectively prevents the airflow from flowing out along the sound outlet of the sound inlet 1135 from flowing in the gap between the sound guide seat 1132 and the mounting groove 1142 and forming noise, but also the sound guide path with higher airtightness can effectively reduce the probability of frequency band loss of sound, thereby effectively improving the sound pickup effect of the microphone 1131.

[0123] Optionally, as shown in Figures 10 to 13, in some embodiments, the microphone assembly 113 further includes a circuit board 1133. The circuit board 1133 is a plate-shaped element with a microphone 1131 processing circuit. Specifically, the sound guide 1132 is disposed on the side of the circuit board 1133 facing the mounting groove 1142, and the microphone 1131 is disposed on the other side of the circuit board 1133 away from the mounting groove 1142. The circuit board 1133 is provided with a connecting hole 1141, through which the microphone 1131 communicates with the sound output end of the sound guide channel 1136. This arrangement effectively shortens the spatial interval between the microphone 1131 and the microphone 1131 processing circuit, thereby effectively reducing the wiring distance between the microphone 1131 and the microphone 1131 processing circuit and improving the space utilization rate inside the housing assembly 110. Furthermore, in some embodiments, the microphone 1131 can be directly mounted on the circuit board 1133. The microphone 1131 is connected to the microphone 1131 processing circuit through the circuit board 1133, thereby eliminating the need for additional circuit lines to route the microphone 1131. This further improves the space utilization inside the housing assembly 110 while effectively simplifying the overall structure of the earphone 10.

[0124] It should be noted that in this embodiment, the circuit board 1133 may be a main control circuit board 112 that integrates the microphone 1131 processing circuit and the main control circuit. In other embodiments, the circuit board 1133 may only be provided with the microphone 1131 processing circuit as a dedicated circuit element for the microphone 1131.

[0125] Furthermore, in some embodiments, the circuit board 1133 also acts as a support, pressing and fixing the sound guide 1132 within the mounting groove 1142. This arrangement effectively improves the connection stability between the sound guide 1132 and the mounting groove 1142. Moreover, the stacked arrangement of the sound guide 1132, circuit board 1133, and microphone 1131 effectively improves the utilization rate of the internal space of the housing assembly 110. Specifically, the side of the circuit board 1133 facing the inner wall abuts against the side of the sound guide 1132 facing the inside of the earphone.

[0126] Optionally, as shown in Figures 10 and 12, in some embodiments, the microphone assembly 113 further includes a seal 1137 disposed between the circuit board 1133 and the sound guide 1132. The seal 1137 is disposed around the sound outlet end of the sound guide channel 1136 and the sound inlet end of the connecting hole 1141. This arrangement allows the seal 1137 to effectively seal the area between the circuit board 1133 and the sound guide 1132, thereby effectively sealing the area between the sound outlet end of the sound guide channel 1136 and the sound inlet end of the connecting hole 1141, further improving the sound pickup effect of the microphone 1131. The seal 1137 can be a rubber ring, adhesive, etc.

[0127] Preferably, as shown in Figures 10 and 12, in some embodiments, an annular groove 1138 is provided on the circuit board 1133 or the sound guide seat 1132, and the sealing member 1137 is disposed in the annular groove 1138. The sound outlet end of the sound guide channel 1136 and the sound inlet end of the connecting hole 1141 are located within the area enclosed by the annular groove 1138. The annular groove 1138 can provide better positioning for the sealing member 1137. During the assembly process, installing the sealing member 1137 through the annular groove 1138 can effectively improve the installation accuracy of the sealing member 1137 and effectively prevent the sealing member 1137 from blocking the sound outlet end of the sound guide channel 1136 and the sound inlet end of the connecting hole 1141 due to installation errors. Furthermore, 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 or / and the sound guide seat 1132, and prevent the seal 1137 from shifting relative to the sound guide seat 1132 and the circuit board 1133 due to vibration, compression and other factors, which would affect the sealing effect between the sound outlet end of the sound channel and the sound inlet end of the connecting hole 1141.

[0128] Optionally, in some embodiments, the seal 1137 is integrally formed with the sound guide seat 1132 and protrudes from the sound guide seat 1132, which can effectively simplify the composition structure of the earphone 10 and thus effectively improve the assembly efficiency of the earphone 10.

[0129] Optionally, in some embodiments, the sound guide seat 1132 may be made of a flexible material such as rubber.

[0130] Optionally, as shown in Figure 12, in some embodiments, along the spacing direction X2 between the sound guide 1132 and the two sound inlets 1135, the sound outlets of the two sound inlets 1135 and the sound inlet of the sound guide channel 1136 are relatively spaced apart, so as to form a larger gap between the sound inlet of the sound guide channel and the sound outlets of the two sound inlets 1135, thereby reducing the airflow velocity to a certain extent, and thus effectively reducing wind noise during sound pickup, thereby effectively improving the sound pickup effect of the microphone 1131. Furthermore, the spaced arrangement between the sound inlet of the sound guide channel 1136 and the sound outlets of the two sound inlets 1135 can also effectively reduce the probability of airflow directly flowing into the sound guide channel 1136, thereby effectively reducing the probability of airflow impacting the microphone 1131, and thus effectively improving the sound pickup effect of the microphone 1131.

[0131] It is worth noting that in any embodiment of the earphone 10 described herein, the spacing direction X2 between the sound guide 1132 and the two sound inlets 1135 is parallel to the thickness direction X of the housing assembly 110.

[0132] Preferably, as shown in FIG13, in some embodiments, the sound outlets of the two inlet holes 1135 are located at the bottom of the mounting groove 1142. The bottom of the mounting groove 1142 is provided with a first groove 1139 recessed in the direction away from the sound guide seat 1132, and the sound outlets of the two 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 inlet holes 1135, so that the airflow flowing in from one of the two inlet holes 1135 can flow smoothly along the first groove 1139 to the other of the two inlet holes 1135, and then flow out of the earphone 10, thereby effectively slowing down the airflow velocity and thus effectively improving the sound pickup effect of the microphone 1131. Furthermore, the first groove 1139 can also effectively increase the spacing distance and the size of the spacing space between the sound outlets of the two inlet holes 1135 and the inlet end of the sound guide channel 1136, thereby effectively slowing down the airflow velocity and thus effectively improving the sound pickup effect of the microphone 1131.

[0133] Preferably, as shown in FIG13, in some embodiments, the groove depth c1 of the first groove 1139 is set to 0.25-0.55mm, for example, actual values ​​between 0.25mm and 0.55mm such as 0.25mm, 0.30mm, 0.4mm, and 0.55mm. This ensures efficient space utilization of the housing assembly 110 while effectively improving the sound pickup effect of the microphone 1131. 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 depth of the inlet hole 1135 to ensure sound conduction. Increasing the thickness of the housing assembly 110, without changing the overall structural dimensions of the earphone 10, will inevitably reduce the internal space of the housing assembly 110, affecting the arrangement of other components of the earphone 10. Conversely, if the groove depth c1 of the first groove 1139 is too shallow, it will be difficult to guide airflow from one inlet hole 1135 to the other, thus affecting the sound pickup effect of the microphone 1131.

[0134] Optionally, as shown in Figures 10 and 11, in some embodiments, the earphone 10 further includes an acoustic barrier 1134. The bottom of the mounting groove 1142 has a pre-reserved annular platform 1143 around the sound outlet ends of the two sound inlets 1135 and the first groove 1139. The sound guide seat 1132 presses and fixes the acoustic barrier 1134 onto the annular platform 1143. The acoustic barrier 1134 further covers the sound outlet ends of the two sound inlets 1135 and the first groove 1139.

[0135] Optionally, as shown in Figure 12, in some embodiments, the sound guide 1132 has a second groove 1140 recessed in the direction away from the two sound inlets 1135 on the side facing the two sound inlets 1135. The sound outlets of the two sound inlets 1135 are further connected to each other through the second groove 1140, and the sound inlet of the sound guide channel 1136 is disposed in the second groove 1140. Specifically, the second groove 1140 cooperates with the first groove 1139 to form a connecting channel between the two sound inlets 1135. This can effectively increase the distance between the sound outlets of the two sound inlets 1135 and the sound inlet of the sound guide channel, thereby further reducing the airflow velocity and further improving the sound pickup effect of the microphone 1131. Furthermore, by providing a second groove 1140 on the sound guide seat 1132, the space utilization rate of the housing assembly 110 can be effectively increased while effectively reducing the impact of the first groove 1139 on the space utilization rate of the housing assembly 110 (the specific impact of the groove depth c1 of the first groove 1139 on the space utilization rate of the housing assembly 110 can be found in the above description, which will not be elaborated here). This further reduces the airflow velocity and further improves the sound pickup effect of the microphone 1131.

[0136] Preferably, in some embodiments, the sound guide seat 1132 is provided with an annular flange 1144 on the side facing the two sound inlets 1135. The annular flange 1144 surrounds and forms a second groove 1140. The annular flange 1144 is embedded in the mounting groove 1142 and presses and fixes the sound barrier 1134 on the annular platform 1143. The sound barrier 1134 further covers the sound outlet ends of the two sound inlets 1135 and the first groove 1139.

[0137] Specifically, the acoustic barrier 1134 is disposed between the sound outlet of the two sound inlets 1135 and the sound inlet of the sound guide channel 1136 in the manner described above. This effectively slows down the flow rate of the airflow flowing in through the two sound inlets 1135, thereby effectively reducing the probability of the airflow impacting the microphone 1131 through the sound guide channel 1136. This reduces wind noise during sound pickup and effectively improves the sound pickup effect of the microphone 1131.

[0138] Optionally, in some embodiments, the extension direction of the mesh of the acoustic barrier 1134 is at least partially set to intersect with the spacing direction X2. This setting can effectively increase the blocking effect of the acoustic barrier 1134 on the airflow, thereby effectively reducing the probability of the airflow impacting the microphone 1131 through the sound guide channel 1136, thereby reducing wind noise during sound pickup and effectively improving the sound pickup effect of the microphone 1131.

[0139] Optionally, in some embodiments, the acoustic network includes at least a mesh and a steel mesh stacked along the spacing direction X2. The steel mesh can be a 3D woven mesh, with the angle between the extension direction of the mesh openings and the spacing direction X2 being 45°, thus effectively improving the steel mesh's airflow blocking effect.

[0140] Optionally, in some embodiments, the acoustic network includes at least two layers of steel mesh stacked along the X2 interval direction to further improve the sound pickup effect.

[0141] Optionally, as shown in FIG12, 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 interval direction X2 falls into the second groove 1140.

[0142] Preferably, in some embodiments, the groove depth c2 of the second groove 1140 is set to 0.2–0.5 mm, for example, actual values ​​between 0.25 and 0.50 mm such as 0.25 mm, 0.30 mm, 0.4 mm, and 0.50 mm. This allows for a more reasonable structural dimension setting of the sound guide 1132, ensuring the space utilization of the housing assembly 110 while effectively increasing the distance between the sound outlets of the two sound inlets 1135 and the sound inlet 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, it will increase the structural dimension of the sound guide 1132, thus affecting the space utilization of the housing assembly 110. If the groove depth c2 of the second groove 1140 is too small, it will reduce the distance between the sound outlets of the two sound inlets 1135 and the sound inlet of the sound guide channel.

[0143] Optionally, in some embodiments, the projection of the sound inlet end of the sound guide channel 1136 along the spacing direction X2 is at least partially located in the gap region between the two sound inlets 1135. This arrangement ensures that the projection of the sound inlet end of the sound guide channel 1136 along the spacing direction X2 does not completely overlap with the projection of the sound outlet end of either of the two sound inlets 1135, thereby effectively preventing airflow from flowing directly into the sound guide channel 1136 after exiting along the sound outlet end of one of the sound inlets 1135, thus effectively improving the sound pickup effect of the microphone 1131.

[0144] Optionally, in some embodiments, the sound-conducting channel 1136 has a center line z2 parallel to the spacing direction X2 at its inlet end, and the sound-exit ends of the two inlet holes 1135 each have a center line (z3 and z4) parallel to the spacing direction X2. The center line z2 of the sound-conducting channel 1136 at its inlet end is located between the center lines z3 and z4 of the sound-exit ends of the two inlet holes 1135, and the center line z2 of the sound-conducting channel 1136 and the center lines (z3 and z4) of the sound-exit ends of the two inlet holes 1135 are all located in the same vertical plane. This ensures that the sound-conducting channel 1136 has a center line z2 parallel to the spacing direction X2 at its inlet end, and the sound-exit ends of the two inlet holes 1135 are all located in the same vertical plane. The projection of the sound inlet end of the sound channel 1136 along the interval direction X2 includes a first projection portion that overlaps with the projection of the sound outlet end of one of the sound inlets 1135, a second projection portion that overlaps with the projection of the sound outlet end of the other sound inlet 1135, and a third projection portion that does not overlap with the projections of the sound outlet ends of the two sound inlets 1135 respectively. The areas of the first projection portion and the second projection portion are equal. This arrangement can effectively reduce the sound difference introduced into the sound channel 1136 along the two sound inlets 1135 respectively, thereby effectively improving the sound pickup effect of the microphone 1131.

[0145] Optionally, in some embodiments, the two sound inlets 1135 have the same structure, which can effectively reduce the difference in sound introduced along the two sound inlets 1135 respectively, thereby effectively improving the sound pickup effect of the microphone 1131.

[0146] Optionally, as shown in Figures 3 and 4, in some embodiments, the housing assembly 110 includes a first housing 1101 and a second housing 1102 that fit together along a preset mating direction. The preset mating direction is parallel to the thickness direction X of the housing assembly 110. In the wearing state, along the preset mating direction, the first housing 1101 is located closer to the ear, and the second housing 1102 is located away from the ear. The mounting groove 1142 and two sound inlets 1135 are disposed on the second housing 1102, and the sound inlets of the two sound inlets 1135 are located on the side of the second housing 1102 away from the first housing 1101 along the thickness direction. This effectively prevents the sound inlets of the two sound inlets 1135 from being blocked by the user's ear or head, thereby effectively improving the sound pickup effect of the microphone 1131.

[0147] Optionally, as shown in Figures 4, 12, and 13, the housing assembly 110 further includes a flexible covering layer 1104. The flexible covering layer 1104 covers at least the outer surface of the second housing 1102 where the sound inlets 1135 are located. The flexible covering layer 1104 has through holes corresponding to the two sound inlets 1135 at positions corresponding to the two sound inlets 1135. Each through hole serves as an extension 1155 of the sound inlet end of the two sound inlets 1135, allowing the two sound inlets 1135 to connect the inner and outer sides of the housing assembly 110. Furthermore, the flexible covering layer 1104 is provided on the outer surface of the second housing 1102 where the sound inlets 1135 are located. The flexible covering layer 1104 can, to a certain extent, block noise from the external environment, thereby reducing noise flowing into the sound guide channel 1136 and effectively improving the sound pickup effect of the microphone 1131.

[0148] Optionally, in some embodiments, the flexible cover layer 1104 completely covers the outer surface of the second housing 1102.

[0149] Optionally, as shown in FIG14, in some embodiments, the loudspeaker 111 is an air-conducting loudspeaker 111, wherein the loudspeaker 111 includes a diaphragm 1111, a fixing ring 1112, and a frame 1114. The diaphragm 1111 includes a vibrating body 1111a and an annular fixing part 1111b connected to the vibrating body 1111a and surrounding the vibrating body 1111a. The fixing ring 1112 is connected and fixed to the annular fixing part 1111b and is sleeved on the frame 1114. The annular fixing part 1111b and the fixing ring 1112 have a first connection length L1 along the axial direction z5 of the loudspeaker 111 and a second connection length L2 along the radial direction of the loudspeaker 111. The first connection length L1 is greater than the second connection length L2.

[0150] Specifically, the diaphragm 1111 includes a vibrating body 1111a and an annular fixing part 1111b. Under electromagnetic influence, the vibrating body 1111a can move relative to the frame 1114 and the annular fixing part 1111b along a preset vibration direction of the speaker 111 to convert electromagnetic signals into sound. The annular fixing part 1111b is fixed to the frame 1114 via a fixing ring 1112. That is, the fixing ring 1112 is sleeved on one end of the frame 1114 and fixedly connected to the frame 1114, and the annular fixing part 1111b is fixedly connected to the fixing ring 1112. This arrangement allows the diaphragm 1111 to be fixed to the frame 1114 via the fixing ring 1112. The frame 1114 is used to fix the sound-generating components, including the diaphragm 1111, magnetic circuit assembly 1115, and voice coil 1113, within the housing assembly 110. When the diaphragm 1111 vibrates, some of the vibration energy is transmitted to the frame 1114, and then to the housing assembly 110 and even the entire headphone 10. This causes noise in the headphone 10 that interferes with the normal sound production of the speaker 111, thus affecting the sound quality of the headphone 10. Therefore, a fixing ring 1112 is provided between the frame 1114 and the diaphragm 1111 so that the diaphragm 1111 is fixedly connected to the frame 1114 through the fixing ring 1112. This effectively reduces the vibration energy transmitted from the diaphragm 1111 to the frame 1114, thereby effectively reducing the noise caused by the headphone 10 and effectively improving the sound quality of the headphone 10. Preferably, the fixing ring 1112 may be made of a flexible material, so that the fixing ring 1112 has structural rigidity while also having a certain degree of flexibility. This can further reduce the vibration energy transmitted from the diaphragm 1111 to the frame 1114, thereby effectively reducing the noise of the headphones 10 and effectively improving the sound quality of the headphones 10. Preferably, the fixing ring 1112 and the annular fixing part 1111b and / or the fixing ring 1112 and the frame 1114 can be fixedly connected by adhesive or the like using a dispensing method. This can further reduce the vibration energy transmitted from the diaphragm 1111 to the frame 1114, thereby effectively reducing the noise of the headphones 10 and effectively improving the sound quality of the headphones 10.

[0151] Specifically, in some embodiments, the connection between the annular fixing part 1111b and the fixing ring 1112 includes a lateral connection (i.e., as described above, a first connection length L1 is provided between the annular fixing part 1111b and the fixing ring 1112) and a radial connection (i.e., as described above, a second connection length L2 is provided between the annular fixing part 1111b and the fixing ring 1112). Preferably, in some embodiments, the connection between the annular fixing part 1111b and the fixing ring 1112 is mainly a lateral connection, supplemented by a radial connection (i.e., the first connection length L1 described above is greater than the second connection length L2). The radial connection serves as an auxiliary connection between the annular fixing part 1111b and the fixing ring 1112. Provided that the lateral connection is sufficient to maintain the connection stability between the annular fixing part 1111b and the fixing ring 1112, the radial connection may not be provided between the annular fixing part 1111b and the fixing ring 1112. In other words, the first connection length L1 cannot be less than zero, while the second connection length L2 can be set to zero.

[0152] It should be noted that the annular fixing part 1111b and the fixing ring 1112 are connected by a lateral connection as the main method and a radial connection as the auxiliary method. This can ensure the connection stability between the annular fixing part 1111b and the fixing ring 1112, while also effectively reducing the radial dimension of the fixing ring 1112, thereby effectively reducing the radial dimension of the speaker 111 and thus effectively reducing the overall volume of the speaker 111. Specifically, as the main component for sound generation, the radial dimension of the diaphragm 1111, especially the radial dimension of the vibrating body 1111a, directly affects the sound quality of the speaker 111. Generally, the larger the radial dimension of the vibrating body 1111a, the better the sound quality of the speaker 111. Therefore, the annular fixing part 1111b and the fixing ring 1112 are mainly connected by a lateral connection. Under the premise of ensuring the connection stability between the annular fixing part 1111b and the fixing ring 1112, the radial dimension of the vibrating body 1111a of the diaphragm 1111 can be made larger (which can also be understood as the speaker 111 being able to be equipped with a diaphragm 1111 with a larger radial dimension of the vibrating body 1111a). This effectively improves the sound quality of the speaker 111 while also effectively reducing the overall size of the speaker 111.

[0153] Optionally, in some embodiments, the ratio between the first connection length L1 and the second connection length L2 is greater than 4. This effectively improves the connection stability between the diaphragm 1111 and the fixing ring 1112, thereby improving the sound quality of the speaker 111 while also effectively reducing the overall size 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 dimension of the fixing ring 1112 needs to be to connect with the diaphragm 1111; conversely, the larger the radial dimension of the fixing ring 1112, the larger the radial dimension of the speaker 111.

[0154] 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 an actual value of not less than 0.5 mm, such as 0.5 mm, 0.6 mm, 0.8 mm, or 0.9 mm, to ensure the connection stability between the fixing ring 1112 and the annular fixing part 1111b. Specifically, the fixing ring 1112 and the annular fixing part 1111b are mainly connected by a lateral connection. The first connection length L1 should not be too small. If the first connection length L1 is too small, it will cause the connection between the fixing ring 1112 and the annular fixing part 1111b to 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 an actual value between 0.5 and 1.5 mm, such as 0.5 mm, 0.6 mm, 0.8 mm, 0.9 mm, or 1.5 mm.

[0155] Preferably, in some embodiments, the second connection length L2 is no greater than 0.2 mm. For example, the second connection length L2 can be an actual value no greater than 0.2 mm, such as 0 mm, 0.1 mm, 0.12 mm, or 0.15 mm, to reduce the radial dimension of the speaker 111. Specifically, the fixing ring 1112 and the annular fixing part 1111b are mainly connected by a lateral connection. When the connection strength is sufficient, the second connection length L2 can be minimized to control the radial dimension of the fixing ring 1112 to be smaller, thereby further reducing the radial dimension of the speaker 111.

[0156] It should be noted that when there is only a lateral connection between the annular fixing part 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 be infinitely large. In this case, 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 part 1111b and the fixing ring 1112.

[0157] Optionally, as shown in Figures 15 and 16, in some embodiments, the fixing ring 1112 includes a cylindrical body 1112a sleeved on the basin frame 1114. The height H4 of the cylindrical body 1112a along the axial direction z5 is greater than the wall thickness H3 of the cylindrical body 1112a along the radial direction. The annular fixing part 1111b is connected and fixed to the inner or outer circumferential surface of the cylindrical body 1112a to form a first connection length L1. The annular fixing part 1111b is also connected and fixed to the end face of the cylindrical body 1112a (that is, the end face of the cylindrical body 1112a near the vibrating body 1111a along the axial direction z5) to form a second connection length L2. Alternatively, the annular fixing part 1111b is only connected and fixed to the inner or outer circumferential surface of the cylindrical body 1112a, so that the second connection length L2 is zero.

[0158] It should be noted that the cylindrical body 1112a can be understood as having an overall cylindrical structure. Along the axial direction z5, the outline of the cylindrical body 1112a can be set based on the structural shape of the diaphragm 1111. For example, along the axial direction z5, the overall structural shape of the diaphragm 1111 can be racetrack-shaped, circular, or square, etc. Correspondingly, along the axial direction z5, the outline of the cylindrical body 1112a can be set as a racetrack-shaped, circular, or square structural shape, etc.

[0159] Specifically, in some embodiments, the annular fixing part 1111b includes a first folded edge 1111c surrounding the outer periphery of the vibrating body 1111a and connected to the vibrating body 1111a, and a second folded edge 1111d connected to the first folded edge 1111c. The second folded edge 1111d is an annular folded edge extending along the axial direction z5 of the speaker 111. The second folded edge 1111d is connected and fixed to the outer or inner periphery 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. 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 on the side close to the vibrating body 1111a along the axial direction z5) to form a second connection length L2. In this way, the annular fixing part 1111b is connected and fixed in a way that is mainly lateral connection and secondarily radial connection (that is, the second connection length L2 is set between the annular fixing part 1111b and the cylindrical body 1112a). This effectively improves the sound quality of the speaker 111 while also effectively reducing the overall size of the speaker 111.

[0160] Optionally, as shown in Figures 15 and 16, in some embodiments, the diaphragm 1111 is connected and fixed to the inner or outer circumferential surface of the cylindrical body 1112a only through the second folded edge 1111d. That is, only the first connection length L1 is provided between the annular fixing part 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.

[0161] Optionally, in some embodiments, the annular fixing part 1111b may not have the first folded edge 1111c. The outer periphery of the vibrating body 1111a extends directly toward the axial direction z5 of the speaker 111 to form the second folded edge 1111d. The second folded edge 1111d is connected and fixed to the outer or inner periphery of the cylindrical body 1112a to form the first connection length L1. This further improves the sound quality of the speaker 111 while also further reducing the overall volume of the speaker 111.

[0162] Optionally, in some embodiments, the outer peripheral surface of the cylindrical body 1112a is the outer sidewall of the cylindrical body 1112a along the radial direction of the speaker 111. The inner peripheral surface of the cylindrical body 1112a can be the inner sidewall of the cylindrical body 1112a along the radial direction of the speaker 111.

[0163] Optionally, in some embodiments, the end face of the cylindrical body 1112a near the vibrating body 1111a along the axial direction z5 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.

[0164] Optionally, as shown in FIG16, in some embodiments, the annular fixing portion 1111b has a radial thickness H1, which is less than the first connection length L1. Specifically, the radial thickness of the annular fixing portion 1111b is the thickness of the second folded edge 1111d. If the thickness H1 of the annular fixing portion 1111b is too large, it will increase the radial dimension of the speaker 111. If the thickness H1 of the annular fixing portion 1111b is too small, it will affect the structural strength of the annular fixing portion 1111b, 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 dimension of the speaker 111, thereby reducing the volume of the speaker 111. Furthermore, in some embodiments, the thickness H1 of the annular fixing part 1111b should not be 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 part 1111b and the fixing ring 1112.

[0165] Optionally, as shown in FIG16, 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 part 1111b and the radial dimension of the speaker 111, then 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. This can effectively improve the connection stability between the cylindrical body 1112a and the annular fixing part, while also effectively reducing the overall volume of the speaker 111. Furthermore, the height H4 of the cylindrical body 1112a is designed based on the first connection length L1. This effectively ensures that after the cylindrical body 1112a is connected to the annular fixing part 1111b, a sufficiently large first connection length L1 can be formed, thereby effectively improving the connection stability between the cylindrical body 1112a and the annular fixing part 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 ensures that after the cylindrical body 1112a is connected to the annular fixing part 1111b, a sufficiently large first connection length L1 can be formed, thereby effectively improving the connection stability between the cylindrical body 1112a and the annular fixing part 1111b.

[0166] Optionally, as shown in Figures 15 and 16, in some embodiments, the fixing ring 1112 further includes an annular flange 1112b that protrudes radially onto the outer peripheral surface of the cylindrical body 1112a. Specifically, the annular flange 1112b is disposed at one end of the cylindrical body 1112a near the frame 1114, thus making the annular flange 1112b 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 further effectively improving the connection stability between the cylindrical body 1112a and the annular fixing part 1111b.

[0167] Optionally, as shown in FIG16, in some embodiments, the ratio of the protrusion distance H2 of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a to the wall thickness H3 of the cylindrical body 1112a is between 0.66 and 1.0. Specifically, if the ratio of the protrusion distance H2 of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a to the wall thickness H3 of the cylindrical body 1112a is too large, the radial dimension of the speaker 111 will increase; if the ratio of the protrusion distance H2 of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a to the wall thickness H3 of the cylindrical body 1112a is too small, the structural strength of the cylindrical body 1112a will decrease. Therefore, the ratio between the protrusion distance of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a and the wall thickness of the cylindrical body 1112a is set between 0.66 and 1.0, which can effectively improve the structural strength of the cylindrical body 1112a, thereby effectively improving the connection stability between the cylindrical body 1112a and the annular fixing part 1111b, and also effectively reducing the overall volume of the speaker 111.

[0168] Optionally, as shown in Figures 14 and 16, in some embodiments, the annular fixing part 1111b is connected and fixed to the outer peripheral surface of the cylindrical body 1112a, and the radial thickness H1 of the annular fixing part 1111b is less than the protrusion distance H2 of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a. Specifically, as described above, the radial thickness H1 of the annular fixing part 1111b is the thickness of the second folded edge 1111d. The thickness of the second folded edge 1111d is less than the protrusion distance H2 of the annular flange 1112b relative to the outer peripheral surface of the cylindrical body 1112a. Based on this, while the inner peripheral surface of the second folded edge 1111d is connected to the outer peripheral surface of the cylindrical body 1112a, along the axial direction z5 of the speaker 111, the end face of the second folded edge 1111d near the annular flange 1112b can also be connected to the annular flange 1112b to form a third connection length L3. This can further improve the connection stability between the annular fixing part 1111b and the cylindrical body 1112a. In this embodiment, the third connection length L3 is greater than zero. In some embodiments, the third connection length L3 is greater than or equal to the radial thickness H1 of the annular fixing portion 1111b, and less than the protrusion distance H2 of the annular flange 1112b relative to the outer circumferential surface of the cylindrical body 1112a. This ensures that the second folded edge 1111d has sufficient connection area on the annular flange 1112b, so that the connection strength at this location is not weaker than at other locations, while also being protected by the annular flange 1112b. Further, in some embodiments, the third connection length L3 is equal to the radial thickness H1 of the annular fixing portion 1111b.

[0169] Optionally, as shown in Figures 14 and 16, in some embodiments, as described above, the annular flange 1112b and the annular fixing portion 1111b further have a third connection length L3 along the radial direction of the speaker 111, wherein the third connection length is equal to the thickness H1 of the annular fixing portion 1111b.

[0170] Optionally, in some embodiments, the basin frame 1114 includes an insertion portion 1114a and a support portion 1114b connected to each other along the axial direction. The radial dimension of the support portion 1114b is larger than that of the insertion portion 1114a, thereby forming an annular platform 1114c 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 platform 1114c. By forming the annular platform 1114c in the above manner, and with the annular flange 1112b supported on the annular platform 1114c, the basin frame 1114 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 (i.e., the preset vibration direction) is parallel to the axial direction z5, there is a risk that the fixing ring 1112 may fall off the basin frame 1114 along the axial direction z5 when the diaphragm 1111 vibrates. Therefore, the fixing ring 1112 is fixed on the annular platform 1114c. The annular platform 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, and thus effectively improving the connection stability between the fixing ring 1112 and the basin frame 1114.

[0171] Optionally, in some embodiments, an adhesive groove 1114d is provided on the annular platform 1114c, and a retaining ring 1112 covers the adhesive groove 1114d. When assembling the retaining ring 1112 and the basin frame 1114, the connection stability between the basin frame 1114 and the retaining ring 1112 can be strengthened by adding fixing glue into the adhesive groove 1114d.

[0172] Optionally, in some embodiments, the adhesive reservoir is located near the outer periphery of the insertion portion 1114a along the radial direction (radial direction of the speaker 111), so that the adhesive reservoir 1114d is far away from the outer periphery of the support portion 1114b. When the frame 1114 and the retaining ring 1112 are fixedly connected by adhesive, the risk of adhesive overflowing to the outer periphery of the support portion 1114b can be reduced.

[0173] Optionally, as described above, the loudspeaker 111 further includes a magnetic circuit assembly 1115 and a voice coil 1113. The magnetic circuit assembly 1115 forms a magnetic gap, and the frame 1114 surrounds the outer periphery of the magnetic circuit assembly 1115 and is fixedly disposed relative to it. One end of the voice coil 1113 is fixedly connected to the vibrating body 1111a, and the other end extends into the magnetic gap and couples with the magnetic circuit assembly 1115 under the action of an electrical signal, thereby driving the vibrating body 1111a to reciprocate along the axial direction z5, thus producing sound.

[0174] 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 housing assembly 110.

[0175] Optionally, as shown in Figures 17 to 22, in some embodiments, the earphone 10 includes an antenna pattern 115, which 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 feed point 1151b for receiving a feed signal is provided on the first antenna pattern 115a. When a feed signal (i.e., an alternating electrical signal) is output to the feed point 1151b on the first antenna pattern 115a, a changing current is formed on the first antenna pattern 115a. Furthermore, the second antenna pattern 115b can be coupled to the first antenna pattern 115a to disperse the current on the first antenna pattern 115a, thereby preventing the current generated based on the feed signal from being completely concentrated on the first antenna pattern 115a, and thus effectively reducing the SAR value of the antenna pattern 115.

[0176] Specifically, the main surface of the first antenna pattern 115a, i.e., the extended plane of the first antenna pattern 115a, is disposed perpendicular to the thickness direction X of the housing assembly 110 in some embodiments. In some embodiments, the first antenna pattern 115a has a starting end 1151a (the starting end 1151a has an endpoint G) and a free end 1152a (the free end 1152a has an endpoint H), and extends from the endpoint G of the starting end 1151a to the endpoint 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.

[0177] Optionally, in some embodiments, the first antenna pattern 115a may be bent along its extension direction to form a first semi-closed structure with a first opening 115c. That is, the overall structure of the first antenna pattern 115a presents a curved semi-closed structure, which ensures that the length of the first antenna pattern 115a meets the requirements for Bluetooth signal transmission and / or reception, while also effectively improving the space utilization of the first antenna pattern 115a, thereby effectively reducing the overall structural size of the earphone 10.

[0178] Specifically, the opening direction of the first antenna pattern 115a is defined as follows: when viewed along the direction towards the main surface of the first antenna pattern 115a, the line segment GH formed by connecting the endpoint G of the starting end 1151a and the endpoint H of the free end 1152a of the first antenna pattern 115a is perpendicular to the line segment GH and points to the outside of the first semi-closed structure, which is the first opening direction X3.

[0179] Furthermore, in some embodiments, when viewed along the direction toward the main surface of the first antenna pattern 115a, the projection of the second antenna pattern 115b in the opposite direction to the opening direction (i.e., the first opening direction X3) of the first antenna pattern 115a at least partially coincides with the first antenna pattern 115a. This arrangement ensures that the second antenna pattern 115b is at least partially located inside the first semi-enclosed structure formed by the first antenna pattern 115a or on one side of the first semi-enclosed structure along the first opening direction X3. This arrangement effectively improves the overall space utilization of the antenna pattern 115, allowing the antenna pattern 115 to be arranged on the earphone 10 with a smaller spatial structure size.

[0180] Further, as shown in Figures 20 to 22, in some embodiments, the arc-to-chord ratio of the first antenna pattern 115a is not less than 2. Specifically, the arc-to-chord ratio of the first antenna pattern 115a is the ratio of the extension length of the first antenna pattern 115a to the line segment GH connecting the two endpoints (endpoint G and endpoint H) of the first antenna pattern 115a. Setting the arc-to-chord ratio of the first antenna pattern 115a to not less than 2, for example, this arc-to-chord ratio can be 2, 2.5, 3, etc., can effectively increase the bending degree of the first antenna pattern 115a, thereby effectively improving the space utilization of the first antenna pattern 115a. The extension length of the first antenna pattern 115a is the length of the arc GH between the endpoint G of the starting end 1151a and the endpoint H of the free end 1152a along the extension direction of the first antenna pattern 115a.

[0181] Optionally, as shown in Figures 20 and 21, in some embodiments, the first antenna pattern 115a and the second antenna pattern 115b are spaced apart. The second antenna pattern 115b is provided with a grounding point 1154a for grounding, serving 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 through coupling. A feed point 1151b is located on the first antenna pattern 115a and close to one end of the first antenna pattern 115a (for example, in some embodiments, the feed point 1151b is located at the end point G of the starting end 1151a of the first antenna pattern 115a). Thus, a feed signal is directly transmitted to the first antenna pattern 115a through the feed point 1151b. Due to the coupling between the first antenna pattern 115a and the second antenna pattern 115b, the feed signal that originally acted entirely on the first antenna pattern 115a can be distributed to both the first antenna pattern 115a and the second antenna pattern 115b through 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 feed 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. This effectively prevents the current generated by the feed 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 effectively reducing the SAR value of the antenna pattern 115. Preferably, in some embodiments, the grounding point 1154a is set as far away from the feed point 1151b as possible, which can further disperse the current, thereby further dispersing the energy hotspots on the antenna pattern 115 and further reducing the SAR value of the antenna pattern 115.

[0182] Preferably, as shown in Figures 20 and 21, 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 feed signal. This setting enables the overall length of the antenna pattern 115 to be half the wavelength of the feed signal, thereby effectively improving the antenna functional stability of the antenna pattern 115.

[0183] Optionally, as shown in Figures 20 and 21, in some embodiments, the second line pattern 115b is at least partially wavy, which can effectively extend the length of the second line pattern 115b within a limited space while also effectively improving the space utilization of the second line pattern 115b. For example, as shown in Figure 21, in some embodiments, the second line pattern 115b can also be configured as a shape with multiple "V" shaped bends connected together.

[0184] Optionally, as shown in Figures 20 and 21, in some embodiments, the second antenna pattern 115b is at least partially located inside the first semi-enclosed structure. This arrangement allows the second antenna pattern 115b to effectively utilize the area enclosed by the first semi-enclosed structure, thereby making the second antenna pattern 115b and the first antenna pattern 115a more compact and effectively improving the space utilization of the antenna pattern 115.

[0185] 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, such that the first pattern portion 1151, the second pattern portion 1152, and the third pattern portion 1153 form a first semi-enclosed structure. In this embodiment, the first semi-enclosed structure is U-shaped. In some embodiments, the first semi-enclosed structure may be a C-shaped, V-shaped, or other semi-enclosed curved structure. 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. The projection of the second antenna pattern 115b in the opposite direction 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 another portion extends through and through the opening of the first semi-closed structure (i.e., the first opening 115c). Based on this, the second antenna pattern 115b and the first antenna pattern 115a are more compact, effectively improving the space utilization of the antenna pattern 115.

[0186] Optionally, as shown in FIG20, in some embodiments, at least a portion of the second antenna pattern 115b can be reused for detecting touch signals, which can effectively simplify the structure of the earphone 10 and thus effectively improve the assembly efficiency of the earphone 10. Preferably, in some embodiments, the second antenna pattern 115b includes a block-shaped main body 1154 and a wavy extension 1155 connected to the main body 1154. Specifically, the main body 1154 is reused as the touch pattern 116 of the earphone 10 to receive touch signals. 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.

[0187] Preferably, in some embodiments, the earphone 10 is further provided with a grounding circuit including at least a capacitor, and the first signal terminal of the capacitor is connected to the grounding point 1154a and the second signal terminal of the capacitor is grounded. This arrangement effectively prevents mutual interference between the touch signal and the Bluetooth signal when at least a portion of the second antenna pattern 115b is multiplexed for detecting the touch signal.

[0188] Optionally, as shown in FIG22, in some embodiments, the second antenna pattern 115b is connected to the first antenna pattern 115a with a feed point 1151b as the dividing point. The feed point 1151b is configured to provide feed signals to both the first antenna pattern 115a and the second antenna pattern 115b. This causes the feed signal emitted by the feed point 1151b to be divided into two parts, which flow to the first antenna pattern 115a and the second antenna pattern 115b respectively, effectively distributing the current to the first antenna pattern 115a and the second antenna pattern 115b respectively, thereby effectively reducing the current intensity loaded on the first antenna pattern 115a and the second antenna pattern 115b, and thus effectively reducing the SAR value of the antenna pattern 115. Meanwhile, the first antenna pattern 115a and the second antenna pattern 115b are coupled, and the combined current formed by the feed signal on the first antenna pattern 115a and the combined current formed by the feed signal on the second antenna pattern 115b are mutually inhibiting. Based on this, the magnetic field formed by the combined current on the first antenna pattern 115a and the magnetic field formed by the combined current on the second antenna pattern 115b weaken each other, thereby effectively reducing the magnetic field strength of the combined magnetic field of antenna pattern 115 (that is, the magnetic field formed by the superposition of 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 combined magnetic field entering the user's head, so as to reduce the absorption rate of the combined magnetic field by the human body, and thus effectively reducing the SAR value of antenna pattern 115.

[0189] Optionally, as shown in FIG22, 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. This makes the second antenna pattern 115b generally curved. This arrangement can effectively improve the space utilization of the second antenna pattern 115b. On the other hand, it can also make the current flow on the second antenna pattern 115b generally arc-shaped, corresponding to the arc-shaped current flow on the first antenna pattern 115a (as described above, the first antenna pattern 115a is bent along its extension direction), which is more conducive to forming an electromagnetic field with mutual inhibition. Furthermore, in some embodiments, the projection of the first antenna pattern 115a in the opposite direction to the opening direction (i.e., the second opening direction X4) of the second antenna pattern 115b at least partially overlaps with the second antenna pattern 115b. This arrangement results in an overlap between the first antenna pattern 115a and the second antenna pattern 115b in the first opening direction X3 or the second opening direction X4. That is, the first antenna pattern 115a and the second antenna pattern 115b are positioned opposite each other in the first opening direction X3 or the second opening direction X4. Since the currents on the first antenna pattern 115a and the second antenna pattern 115b flow into or out of the feed point 1151b simultaneously, the electromagnetic fields formed by the first antenna pattern 115a and the second antenna pattern 115b at least in the oppositely positioned portions along the first opening direction X3 or the second opening direction X4 have a mutual inhibition relationship. This effectively reduces the magnetic field strength of the combined magnetic field of the antenna pattern 115, thereby reducing the proportion of the normal component of the combined magnetic field entering the user's head, thus reducing the absorption rate of the combined magnetic field by the human body, and effectively reducing the SAR value of the antenna pattern 115.

[0190] Specifically, referring to Figure 22, the second antenna pattern 115b has a starting end 1156b (the starting end 1156b has an endpoint K) and a free end 1156a (the free end 1156a has an endpoint S), and extends from the endpoint K of the starting end 1156b to the endpoint S of the free end 1156a, thus forming the extension direction of the second antenna pattern 115b. Specifically, the second opening direction X4 is defined as follows: when viewed along the direction towards the main surface of the second antenna pattern 115b, the line segment KS formed by connecting the endpoint K of the starting end 1156b and the endpoint S of the free end 1156a of the second antenna pattern 115b is perpendicular to this line segment KS and points towards the outside of the second semi-closed structure, which is the second opening direction X4.

[0191] Optionally, as shown in FIG22, in some embodiments, in the region near the feed point 1151b, the first antenna pattern 115a and the second antenna pattern 115b are arranged to extend away from each other with the feed point 1151b as the starting point. This arrangement makes the first antenna pattern 115a and the second antenna pattern 115b relatively arranged in the region near the feed point 1151b. This results in the electromagnetic field formed on the first antenna pattern 115a and the electromagnetic field on the second antenna pattern 115b mutually inhibiting each other in the region near the feed point 1151b. This further reduces the magnetic field strength of the combined magnetic field of the antenna pattern 115, 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 combined magnetic field by the human body, and thus effectively reduce the SAR value of the antenna pattern 115.

[0192] Optionally, as shown in FIG22, in some embodiments, the free ends 1152a of the first antenna pattern 115a and the free ends 1156a of the second antenna pattern 115b are arranged adjacent to each other. In the region near the free ends 1152a of the first antenna pattern 115a and the free ends 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 endpoints. This arrangement makes the second opening 115d of the second antenna pattern 115b opposite to the first opening 115c of the first antenna pattern 115a. This makes the combined electromagnetic field (where electromagnetic field is a general term for magnetic field and electric field) that can be formed on the first antenna pattern 115a and the combined electromagnetic field formed on the second antenna pattern 115b mutually exclusive. This effectively reduces the proportion of the normal component of the combined magnetic field that is ultimately formed in the vicinity of the antenna pattern 115 entering the user's head, thereby reducing the absorption rate of the combined magnetic field by the human body and effectively reducing the SAR value of the antenna pattern 115.

[0193] Preferably, as shown in FIG22, in some embodiments, the spacing 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. This arrangement 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 endpoint G of the starting end 1151a and the free end 1152a. The spacing 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 endpoint G of the free end 1152a and the endpoint S of the free end 1156a.

[0194] Furthermore, in some embodiments, the principal plane of the first antenna pattern 115a and the principal plane of the second antenna pattern 115b are arranged parallel to each other or coplanarly. Based on this, 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 entering the user's head, so as to reduce the absorption rate of the human body to the combined magnetic field and thus effectively reduce the SAR value of the antenna pattern 115.

[0195] Optionally, as shown in Figure 22, in some embodiments, the arc-to-chord ratio of the second antenna pattern 115b is not less than 2. Specifically, the second antenna pattern 115b is generally arranged in a curved arc shape, and the length of the second antenna pattern 115b is the length of the arc KS between the endpoint K of the starting end 1156b and the endpoint S of the free end 1156a along the extension direction. The arc-to-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. Setting the arc-to-chord ratio of the second antenna pattern 115b to not less than 2, for example, the arc-to-chord ratio can be 2, 2.5, 3, etc., can effectively increase the degree of bending 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.

[0196] Optionally, in some embodiments, the earphone 10 also includes a touch pattern 116 independent of the antenna pattern 115. The touch pattern 116 is at least partially disposed in the first semi-closed structure and / or the second semi-closed structure, which 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.

[0197] Optionally, in some embodiments, the antenna pattern 115 is disposed on the side of the second housing 1102 opposite to the first housing 1101, thereby maximizing the utilization of the net height of the antenna pattern 115 to improve the performance of the antenna pattern 115.

[0198] 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 disposed close to the second housing 1102 relative to the speaker 111 along the thickness direction X. The main control circuit board 112 is provided with an radio frequency circuit connected to the feed point 1151b and used to output the feed 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 traces between the main control circuit board 112 and the antenna pattern 115, so as to improve the space utilization of the housing assembly 110.

[0199] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
