[0056] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0057] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0058] The following earphone embodiment of the present application describes an exemplary structure of the earphone 100.

[0059] like Figure 1 As shown, the earphone 100 may include a core component 1, an ear hook component 2 and a back hook component 3. The number of core components 1 may be two. The two core components 1 are respectively used to transmit vibration and / or sound to the left ear and right ear of the user. The two core components 1 may be the same or different. For example, one core component 1 may be provided with a microphone, while the other core component 1 may not be provided with a microphone. For another example, one core component 1 may be provided with a button and a corresponding circuit board, while the other core component 1 may not be provided with the button and the corresponding circuit board. The two core components 1 may be the same in the core module (such as a speaker module). The core component 1 described later in this article can be considered to be described in detail by taking one of the two core components 1 as an example. The number of ear hook components 2 may be two, and the two ear hook components 2 can be hung on the left ear and right ear of the user, respectively, so that the core component 1 can fit the user's face. For example, one ear hook component 2 may be provided with a battery, and the other ear hook component 2 may be provided with a control circuit, etc. One end of the earhook assembly 2 is connected to the core assembly 1, and the other end of the earhook assembly 2 is connected to the back-hook assembly 3. The back-hook assembly 3 connects the two earhook assemblies 2. The back-hook assembly 3 is designed to wrap around the back of the user's neck or head and provide a clamping force, allowing the two core assemblies 1 to clamp to the sides of the user's face and the earhook assemblies 2 to be more securely attached to the user's ears. Of course, the earphones 100 can also include no back-hook assembly 3, and the core assembly 1 can be worn on the user's ears via the earhook assemblies 2.

[0060] The following content mainly describes the structure of the core component 1 and other parts of the earphone 100 by way of example.

[0061] like Figure 2 As shown, the core assembly 1 may include a housing assembly 10 , a bone conduction speaker 11 and an air conduction speaker 12 .

[0062] Optionally, the housing assembly 10 may be provided with a mutually isolated accommodating cavity 1001 and an accommodating cavity 1002. The housing assembly 10 may also be referred to as a core housing assembly 10. The bone conduction speaker 11 is provided in the accommodating cavity 1001.

[0063] The air conduction speaker 12 conducts sound into the user's ear canal through the principle of air vibration, and the bone conduction speaker 11 conducts sound to the user through bone conduction vibration. Optionally, the sealing of the accommodating chamber 1001 is greater than the sealing of the accommodating chamber 1002. Sealing can be considered as airtightness. Since the accommodating chamber 1002 in which the air conduction speaker 12 is placed needs to be connected to the outside world to facilitate the conduction of sound waves through the air, the bone conduction speaker 11 and the air conduction speaker 12 are set separately and independently, and there is no need to set the bone conduction speaker 11 in the accommodating chamber 1002. Since the accommodating chambers 1001 are independent of each other, the sealing of the accommodating chamber 1001 can be set higher, thereby effectively improving the sealing effect of the bone conduction speaker 11, thereby preventing the bone conduction speaker 11 from being eroded and damaged by external environmental factors, while ensuring the sound quality of the air conduction speaker 12. In addition, when the bone conduction speaker 11 and the air conduction speaker 12 of the earphone 100 work simultaneously, the mutual interference between the bone conduction speaker 11 and the air conduction speaker 12 can be effectively reduced, thereby effectively improving the sound quality of the earphone 100.

[0064] Optionally, the housing assembly 10 may include a housing 101, a housing 102, and a housing 103, wherein the housing 101 and the housing 102 cooperate with each other to form a receiving chamber 1001. The housing 101 and / or the housing 102 further form a portion of the receiving chamber 1002, and the housing 103 may form another portion of the receiving chamber 1002. Furthermore, the housing 103 cooperates with the housing 101 and / or the housing 102 to form the receiving chamber 1002. Optionally, at least the housing 101 and the housing 102 cooperate to form the receiving chamber 1001, and at least the housing 103 cooperates with the housing 101 to form the receiving chamber 1002.

[0065] Optionally, the vibration direction of the bone conduction speaker 11 is arranged to intersect with the vibration direction of the air conduction speaker 12, and the housing 101 and the housing 102 cooperate with each other along the vibration direction of the bone conduction speaker 11. The housing 103 cooperates with the housing 101 and / or the housing 102 along the vibration direction of the air conduction speaker 12.

[0066] The vibration direction of the bone conduction speaker 11 may also be referred to as the bone conduction vibration direction X1 in this article, and the vibration direction of the air conduction speaker 12 may also be referred to as the air conduction vibration direction X2 in this article, wherein the bone conduction vibration direction X1 and the air conduction vibration direction X2 are not parallel to each other but are arranged in a cross-direction. For example, the bone conduction vibration direction X1 and the air conduction vibration direction X2 are arranged perpendicularly or approximately perpendicularly (for example, 90°±10°). When the bone conduction speaker 11 and the air conduction speaker 12 are working simultaneously, the bone conduction speaker 11 and the air conduction speaker 12 vibrate and work along the bone conduction vibration direction X1 and the air conduction vibration direction X2, respectively. Since the vibration directions of the two are arranged in a cross-direction, the influence of the vibration of the bone conduction speaker 11 on the sound quality of the air conduction speaker 12 caused by the vibration of the two in the same direction can be effectively alleviated.

[0067] See also Figure 2 Optionally, the housing assembly 10 may also be provided with a pressure relief hole 1081 for connecting the accommodating chamber 1002 with the external environment. The pressure relief hole 1081 is provided to extend toward the side where the accommodating chamber 1001 is located. The housing assembly 10 is provided with a pressure relief hole 1081 for relieving pressure for the air conduction speaker 12. The pressure relief hole 1081 connects the accommodating chamber 1002 with the external environment, and the pressure relief hole 1081 extends from the connection point with the accommodating chamber 1002 toward the side where the accommodating chamber 1001 is located.

[0068] The housing assembly 10 may include a partition wall 1012 for isolating the accommodating chamber 1001 from the accommodating chamber 1002. At least a portion of the partition wall 1012 extends toward the side of the accommodating chamber 1001 and forms a portion of the hole wall of the pressure relief hole 1081. The partition wall 1012 is provided on the housing 101. The housing 101 is provided with a sub-accommodating chamber 1010 and a sub-accommodating chamber 1011 located on opposite sides of the partition wall 1012. The opening direction of the sub-accommodating chamber 1010 is provided along the wall surface of the partition wall 1012. Specifically, the opening direction of the sub-accommodating chamber 1010 is parallel or approximately parallel to the wall surface of the partition wall 1012. The opening direction of the sub-accommodating chamber 1011 is provided to intersect the wall surface of the partition wall 1012. Housing 102 is provided with a sub-accommodating chamber 1020, which covers the open end of sub-accommodating chamber 1010. Sub-accommodating chamber 1020 and sub-accommodating chamber 1010 cooperate to form accommodating chamber 1001. Housing 103 is provided with a sub-accommodating chamber 1030, which covers the open end of sub-accommodating chamber 1011. Sub-accommodating chamber 1030 and sub-accommodating chamber 1011 cooperate to form accommodating chamber 1002.

[0069] The following mainly describes the structure of the ear hook component 2 and other parts of the headset 100.

[0070] Combine Figures 3 to 5 The ear hook assembly 2 may include a shell assembly 20 and a button assembly 21. The shell assembly 20 includes a shell 201 and a shell 202. The shell 201 is provided with a receiving cavity 2010. The receiving cavity 2010 has at least one open end 2011. The button assembly 21 is at least partially inserted into the receiving cavity 2010 through the open end 2011. The button assembly 21 cooperates with the shell 201 to form a glue groove 210 visible from the outside of the shell 201 through the open end 2011. The shell 202 is covered on the open end 2011 of the shell 201 and covers the glue groove 210. The open end 2011 refers to the end of the shell 201 where the opening is provided.

[0071] Optionally, a circuit board 28 may be disposed within the housing 2010. The circuit board 28 is used to convert and process electrical signals to support various functions of the headset 100. The button assembly 21 is configured to respond to user pressure and move relative to the circuit board 28, thereby triggering the operation of the circuit board 28. For example, when pressed by the user, the button assembly 21 triggers the circuit board 28 to enable functions such as turning the headset 100 on and off, switching playback content, and increasing or decreasing the volume.

[0072] Combine Figure 9 A battery 29 may also be provided in the accommodating cavity 2010. In some embodiments, one of the housing components 20 of the two ear hook components 2 contains a battery 29, and the other housing component 20 contains a circuit board 28. The two housing components 20 may be the same or different.

[0073] Optionally, one side of the circuit board 28 can be connected to the wire in the accommodating cavity 2010, and the other side of the circuit board 28 is close to the open end 2011 and abuts against the key assembly 21. The circuit board 28 can be assembled into the accommodating cavity 2010 through the open end 2011. By covering the open end 2011 of the shell 201 with the shell 202, the circuit board 28 can be confined to the accommodating cavity 2010. By providing the shell 202 to block the glue groove 210, the appearance of the earphone 100 can be made more beautiful. The shell 202 can also confine part of the key assembly 21 in the accommodating cavity, thereby limiting the key assembly 21 from separating from the shell 201. Optionally, the shell 202 partially or completely blocks the glue groove 210.

[0074] Glue may be provided between the key assembly 21 and the housing 201. Here, "glue" is a general term and can be in various forms, such as solid glue, liquid glue, or semi-solid glue, to provide sealing or fixing. The glue can form a seal between the key assembly 21 and the housing 201, improving the waterproof performance of the earphone 100. The glue can also act as an adhesive to fix the earphones 100. During dispensing, the glue can be in a fluid form, for example, and solidify after a period of time.

[0075] Without the glue groove 210, glue would need to be pre-applied between the button assembly 21 and the housing 201 along the insertion direction before the button assembly 21 is inserted and installed. During the insertion and installation of the button assembly 21, the button assembly 21 could easily squeeze the glue into the housing 2010, affecting the normal operation of the earphone 100. The glue groove 210 is used to hold the glue. By providing the glue groove 210, the glue can be dispensed after the button assembly 21 is inserted and installed, effectively preventing the glue from being pressed into the housing 2010 by the button assembly 21. By setting the glue containing groove 210 to be visible from the outside of the shell 201 through the open end 2011, the glue dispensing operation is facilitated, and the amount of glue dispensed is controlled, thereby reducing the probability of poor sealing of the earphone 100 due to too little glue dispensed. At the same time, the probability of glue seeping onto the outer surface of the shell 201 or seeping into the containing cavity 2010 due to too much glue dispensed is reduced, thereby reducing the adverse effects on the appearance of the earphone 100 and the working state of the earphone 100.

[0076] like Figure 4 、 Figure 6 and Figure 8 As shown, the key assembly 21 may include a key bracket 211, an annular protrusion 2110 is provided on the outer wall surface of the key bracket 211, an annular support table 2012 is provided on the inner wall surface of the shell 201, the annular protrusion 2110 is supported on the annular support table 2012, and the annular protrusion 2110 is sunk a certain distance relative to the opening end 2011, and on the side of the annular protrusion 2110 facing the opening end 2011, the outer wall surface of the key bracket 211 and the inner wall surface of the shell 201 cooperate with each other to form a glue groove 210.

[0077] By positioning the annular projection 2110 on the annular support surface 2012, the annular support surface 2012 restricts the movement of the key holder 211 into the accommodating cavity 2010, thereby ensuring that the key holder 211 is stably supported on the housing 201. During assembly of the key holder 211, the annular support surface 2012 serves to position the key holder 211, facilitating its proper installation and improving assembly efficiency. Furthermore, the support of the annular projection 2110 on the annular support surface 2012 narrows and tortuously creates a flow path for the glue to flow into the accommodating cavity 2010, thereby reducing the amount of glue that flows from the glue groove 210 into the accommodating cavity 2010 during dispensing.

[0078] By setting the annular protrusion 2110 to be sunken a certain distance relative to the open end 2011, the annular protrusion 2110 can form the bottom wall of the adhesive groove 210. Compared to forming the adhesive groove 210 by integral molding, forming the adhesive groove 210 by abutting the button bracket 211 and the housing 201 is a split molding method, which can make the assembly of the earphone 100 more flexible and easier.

[0079] Alternatively, as Figure 5 and Figure 6 As shown, the outer end surface of the key bracket 211, facing away from the accommodating cavity 2010, protrudes beyond the open end 2011. The key assembly 21 includes an elastic pressing member 212 disposed on the outer end surface. The housing 202 is provided with a key hole 2020, through which the elastic pressing member 212 is exposed. By arranging the outer end surface of the key bracket 211, facing away from the accommodating cavity 2010, protruding beyond the open end 2011, the glue in the glue groove 210 can be restricted from flowing toward the key assembly 21 when the glue overflows.

[0080] When a user presses the button assembly 21 on the side facing away from the accommodating cavity 2010, the elastic pressing member 212 elastically deforms. When the user releases the button assembly 21, the elastic pressing member 212 deforms and recovers. The user's pressing action is transmitted to the switch circuit on the circuit board 28 through the elastic deformation or recovery of the elastic pressing member 212, thereby triggering the circuit board 28 to operate. The provision of the button hole 2020 allows the elastic pressing member 212 to deform and recover, and also allows the user's pressing action to be transmitted to the circuit board 28.

[0081] Alternatively, as Figure 5 As shown, the button assembly 21 includes an external pressing member 213. A portion of the external pressing member 213 is inserted into the button hole 2020, while another portion protrudes from the outer surface of the housing 202 to facilitate user pressure. The external pressing member 213 abuts against the elastic pressing member 212, and the user's pressing action is transmitted to the elastic pressing member 212 through the external pressing member 213.

[0082] like Figure 5 and Figure 6 As shown, in the insertion direction of the key assembly 21 relative to the accommodating cavity 2010, the housing 201 includes a first wall portion 2013 and a second wall portion 2014 connected to each other. The second wall portion 2014 is located on the side of the first wall portion 2013 away from the opening end 2011. The annular support table 2012 is located at the connection between the first wall portion 2013 and the second wall portion 2014. Specifically, the inner wall surface of the first wall portion 2013 and the inner wall surface of the second wall portion are connected by the annular support table 2012. The key bracket 211 includes an insertion portion 2111 located on the side of the annular protrusion 2110 away from the opening end 2011. The insertion portion 2111 is inserted into the space enclosed by the second wall portion 2014.

[0083] Optionally, the outer circumference of the insertion portion 2111 can match the inner circumference of the second wall portion 2014. The second wall portion 2014 can position the insertion portion 2111, limiting the relative movement between the key bracket 211 and the housing 201, so that the glue groove 210 can be stable, which is conducive to glue dispensing.

[0084] like Figure 5 and Figure 6 As shown, the housing assembly 20 further includes an elastic covering layer 203 covering the outer surface of the housing 201. On the side of the open end 2011, the housing 201 has an exposed portion 201a not covered by the elastic covering layer 203. The exposed portion 201a is inserted into the housing 202, and the housing 202 abuts against the elastic covering layer 203 along the insertion direction of the exposed portion 201a relative to the housing 202.

[0085] Providing an elastic coating 203 on the outer surface of the housing 201 improves the user's grip comfort when holding the earphone 100 and also increases friction. By inserting the exposed portion 201a of the housing 201 into the housing 202, the housing 201 can position the housing 202, limiting relative movement between the two housings 201 and 202, thereby improving the connection stability between the two housings 201 and 202.

[0086] By arranging the exposed portion 201a of the housing 201 to be uncovered by the elastic coating 203, the elastic coating 203 can be prevented from interfering with the connection between the housing 201 and the housing 202. By arranging the housing 202 to abut the elastic coating 203 along the insertion direction of the exposed portion 201a relative to the housing 202, the outer surface of the housing 202 and the outer surface of the elastic coating 203 can be flush at the abutment point. On the one hand, this makes the housing 202 and the elastic coating 203 more tightly connected at the abutment point, thereby achieving a better sealing effect, reducing the ingress of debris and moisture, and increasing the service life of the elastic coating 203. On the other hand, the flushness at the abutment point can reduce the discomfort caused to the user when being touched, making the earphone 100 more integrated and comfortable, and also making the earphone 100 more beautiful in appearance.

[0087] Furthermore, the shell 202 is not covered by the elastic covering layer 203, so that the button assembly 21 is spaced apart from the elastic covering layer 203 on the side away from the accommodating cavity 2010, thereby preventing the elastic covering layer 203 from interfering with the user's pressing of the button assembly 21 and affecting the user's pressing feel.

[0088] like Figure 5 and Figure 6 As shown, the exposed portion 201a cooperates with the housing 202 to form a glue-containing gap 2003 for communicating with the glue-containing groove 210. The glue-containing gap 2003 can accommodate glue, thereby forming a seal between the exposed portion 201a and the housing 202, and can also play a role in fixing the exposed portion 201a and the housing 202.

[0089] Optionally, the outer end surface of the key bracket 211 facing away from the accommodating cavity 2010 can be configured to protrude from the open end 2011, so that when glue overflows the glue-receiving groove 210, it can flow into the glue-receiving gap 2003. Optionally, before assembling the housing 201 and the housing 202, glue can be dispensed on the outside of the exposed portion 201a or on the inside of the housing 202, so that after the exposed portion 201a and the housing 202 form the glue-receiving gap 2003, the glue can be filled in the glue-receiving gap 2003.

[0090] like Figure 5 and Figure 6 As shown, in the insertion direction of the key assembly 21 relative to the accommodating cavity 2010, the depth H1 of at least part of the glue containing groove 210 is greater than or equal to 0.2 mm. For example, the depth H1 of at least part of the glue containing groove 210 can be 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, or 0.5 mm. Optionally, in the vertical direction of the insertion direction of the key assembly 21 relative to the accommodating cavity 2010, the width L1 of at least part of the glue containing groove 210 is greater than or equal to 0.4 mm. For example, the width L1 of at least part of the glue containing groove 210 can be 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, or 0.8 mm.

[0091] With such a configuration, on the one hand, there can be enough glue in the glue groove 210 so that the glue can have a sufficient sealing or fixing effect. On the other hand, based on the fact that the capacity of the glue groove 210 can accommodate enough glue, since the glue gap 2003 is connected to the glue groove 210, a small amount of glue can be allowed to overflow into the glue gap 2003, further sealing between the shell 201 and the shell 202, thereby enhancing the sealing performance. Moreover, since the existence of the glue gap 2003 can retain glue, the risk of excessive glue seeping out to the outer surface of the shell 201 is alleviated.

[0092] like Figure 3 and Figure 7 As shown, the housing 201 is further provided with a receiving groove 2004 communicating with the receiving cavity 2010. The earphone 100 further includes an interface component 22, which is inserted into the receiving groove 2004, and the housing 202 is configured to partially cover the interface component 22.

[0093] The interface assembly 22 can be used to connect to an external power source to charge the headset 100. The interface assembly 22 can also be used to connect to an external device to transfer data between the external device and the headset 100. For example, the interface assembly 22 can be a Type-C interface, or other types of interfaces, such as a mini-USB interface. Furthermore, the interface assembly 22 can be connected to the circuit board 28 within the accommodating cavity 2010. An external device or external power source can be connected to the interface assembly 22 via the accommodating slot 2004.

[0094] By setting the shell 202 to partially cover the interface component 22, the shell 202 can stop the interface component 22, and limit the interface component 22 from moving out of the shell 202 in a direction away from the accommodating cavity 2010, which is beneficial to the structural stability of the earphone 100 and facilitates the assembly of the interface component 22.

[0095] like Figure 3 、 Figure 7 and Figure 8 As shown, the earphone 100 further includes a dustproof plug 23, which includes a plug body 231 and a fixing portion 232. The fixing portion 232 is located on the shell 201 between the button assembly 21 and the interface assembly 22 through the shell 202. The plug body 231 is connected to the fixing portion 232 and is used to selectively cover the interface assembly 22.

[0096] The dustproof plug 23 can protect the interface component 22 when it blocks the interface component 22. For example, the dustproof plug 23 can be waterproof and dustproof, and can also reduce the risk of mechanical damage to the interface component 22.

[0097] Furthermore, the dust plug 23 may be deformable. Deformation of the dust plug 23 allows the plug body 231 and the fixing portion 232 to move relative to each other. By moving relative to the fixing portion 232, the plug body 231 can switch between blocking the interface assembly 22 and not blocking the interface assembly 22. Specifically, the plug body 231 can block the interface assembly 22 by being inserted into the receiving slot 2004.

[0098] like Figure 7 As shown, the fixing portion 232 can pass through the housing 202 and extend onto the housing 201 between the button assembly 21 and the interface assembly 22, thereby reducing the space occupied by the fixing portion 232 on the outer surface of the housing 202 and improving space utilization. Specifically, the fixing portion 232 can have a groove 2321, and the housing 202 can have a through hole 202a, through which the fixing portion 232 is inserted into the housing 202. The wall of the through hole 202a can be inserted into the groove 2321, thereby being constrained by the groove 2321, so that the bottom wall of the groove 2321 is arranged opposite the wall of the through hole 202a, thereby limiting the relative movement between the housing 202 and the fixing portion 232.

[0099] The dust plug 23 can be made of an elastic material, such as silicone, rubber, etc., so as to facilitate the insertion of the plug body 231 into the receiving groove 2004 and the insertion of the fixing portion 232 into the housing 202, while allowing the dust plug 23 to have deformation ability.

[0100] like Figures 9 to 11As shown, the earhook assembly 2 may include a housing assembly 26. The housing assembly 26 includes a housing 261 and a housing 262 that cooperate with each other. The first of the housings 261 and 262 is provided with a glue-receiving groove 2601. The glue-receiving groove 2601 includes at least a first sidewall 2602 proximal to the interior of the housing assembly 26, a second sidewall 2603 distal to the interior of the housing assembly 26, and a bottom wall connecting the first sidewall 2602 and the second sidewall 2603. The second of the housings 261 and 262 is inserted into the glue-receiving groove 2601, forming a first gap 2604 between the housing 261 and the first sidewall 2602, and a second gap 2605 between the housing 261 and the second sidewall 2603. In the spacing direction between the first sidewall 2602 and the second sidewall 2603, the width L2 of the first gap 2604 is greater than the width L3 of the second gap 2605. The housing 261 may also be referred to as the first housing, and the housing 262 may also be referred to as the second housing.

[0101] For example, a glue containing groove 2601 is provided on the shell 262 , and the shell 261 is inserted into the glue containing groove 2601 .

[0102] The housing 261 and the housing 262 are connected to form a housing cavity 2600 between the housing 261 and the housing 262. The housing cavity 2600 can be used to accommodate some components of the earphone 100. For example, the housing cavity 2600 can be provided with a battery 29. The battery 29 can be used to power the earphone 100.

[0103] Alternatively, as Figure 4 As shown, a circuit board 28 may be disposed within the housing cavity 2600. The circuit board 28 is used to convert and process electrical signals to support various functions of the headset 100. For example, the circuit board 28 may support the headset 100 in performing functions such as powering on and off, switching playback content, and increasing and decreasing the volume. In some embodiments, the two ear hook assemblies 2 may include a housing assembly 20 and a housing assembly 26, one of which contains a battery 29 and the other contains a circuit board 28.

[0104] Glue may be provided between the housing 261 and the housing 262. The glue can form a seal between the housing 262 and the housing 261, thereby improving the waterproof performance of the earphone 100. The glue can also provide a secure fit through adhesion. During dispensing, the glue can be in a fluid form and solidify after a period of time.

[0105] The glue holding groove 2601 can be used to hold glue. By setting the glue holding groove 2601 to be exposed to the outside along the insertion direction of the second one of the shell 261 and the shell 262, the glue dispensing operation is facilitated. By providing the glue holding groove 2601, when dispensing glue into the glue holding groove 2601, it is convenient to control the amount of glue dispensed, thereby reducing the risk of poor sealing of the earphone 100 due to too little glue dispensed, and at the same time reducing the probability of glue infiltrating onto the outer surfaces of the shell 261 and the shell 262 or infiltrating into the accommodating cavity 2600 due to excessive glue dispensed, thereby reducing the adverse effects on the working state of the earphone 100 and the appearance of the earphone 100.

[0106] During the assembly process, glue can be dispensed first, and then the second of the housings 261 and 262 can be inserted into the glue groove 2601, so that the glue fills the first gap 2604 and the second gap 2605, respectively. By setting the width L2 of the first gap 2604 to be greater than the width L3 of the second gap 2605, the second gap 2605 can retain more glue. During the process of inserting the second of the housings 261 and 262 into the glue groove 2601, the glue tends to flow into the second gap 2605, thereby reducing the probability of glue flowing onto the outer surfaces of the housings 261 and 262, which helps maintain the good appearance of the earphone 100.

[0107] Optionally, the second one of the housing 261 and the housing 262 has a connecting boss 2609 , and the connecting boss 2609 is inserted into the glue containing groove 2601 .

[0108] like Figures 11 to 13 As shown, positioning ribs 2606 are provided on the first sidewall 2602 and / or the second sidewall 2603. The positioning ribs 2606 are used to define the widths of the first gap 2604 and the second gap 2605. For example, the positioning ribs 2606 can be provided on the first sidewall 2602. In the spacing direction between the first sidewall 2602 and the second sidewall 2603, the positioning ribs 2606 can prevent the second of the housings 261 and 262 from contacting the first sidewall 2602. When the second of the housings 261 and 262 abuts the positioning ribs 2606, the height of the protrusion of the positioning ribs 2606 can serve as the width L2 of the first gap 2604. When the second of the housings 261 and 262 does not abut the positioning ribs 2606, the width L2 of the first gap 2604 is greater than the height of the protrusion of the positioning ribs 2606. Furthermore, during the design stage of the shell assembly 26, in the spacing direction between the first side wall 2602 and the second side wall 2603, the width L2 of the first gap 2604 can be set to be greater than or equal to the protruding height of the positioning rib 2606, and the width L3 of the second gap 2605 can be set to be less than the protruding height of the positioning rib 2606, so that the width L2 of the first gap 2604 is greater than the width L3 of the second gap 2605.

[0109] For another example, a positioning rib 2606 may be provided on the second sidewall 2603. During the design phase of the housing assembly 26, in the spacing direction between the first sidewall 2602 and the second sidewall 2603, the width L3 of the second gap 2605 may be set equal to the protruding height of the positioning rib 2606, and the width L2 of the first gap 2604 may be set greater than the protruding height of the positioning rib 2606, thereby making the width L2 of the first gap 2604 greater than the width L3 of the second gap 2605. During the assembly process of inserting the second of the housings 261 and 262 into the adhesive receiving groove 2601, the second of the housings 261 and 262 must be kept in contact with the positioning rib 2606, so that the width L3 of the second gap 2605 is equal to the protruding height of the positioning rib 2606, and thus the width L3 of the second gap 2605 is smaller than the width L2 of the first gap 2604.

[0110] For another example, positioning ribs 2606 are provided on both the first side wall 2602 and the second side wall 2603. In the direction of separation between the first side wall 2602 and the second side wall 2603, the protruding height of the positioning ribs 2606 on the first side wall 2602 is greater than the protruding height of the positioning ribs 2606 on the second side wall 2603. During the assembly process of inserting the second of the housings 261 and 262 into the adhesive receiving groove 2601, the second of the housings 261 and 262 must be kept in contact with the positioning ribs 2606 on the second side wall 2603, so that the width L2 of the first gap 2604 is greater than the width L3 of the second gap 2605.

[0111] Optionally, there are two or more positioning ribs 2606 , and the two or more positioning ribs 2606 are distributed at intervals.

[0112] In some embodiments, combined Figure 12 and Figure 13 , the positioning rib 2606 is set on the first side wall 2602.

[0113] In some embodiments, combined Figure 10 and Figure 11 The difference between the width L2 of the first gap 2604 and the width L3 of the second gap 2605 is greater than or equal to 0.05 mm. For example, the difference between the width L2 of the first gap 2604 and the width L3 of the second gap 2605 may be 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm.

[0114] Such a configuration ensures that when the second of the shells 261 and 262 is inserted into the glue groove 2601 , the amount of glue flowing into the second gap 2605 is within an acceptable range, thereby preventing the glue from flowing onto the outer surfaces of the shells 261 and 262 .

[0115] As the height of first gap 2604 relative to the bottom wall of adhesive groove 2601 changes at different locations, the width L2 of first gap 2604 may vary. As the height of second gap 2605 relative to the bottom wall of adhesive groove 2601 changes at different locations, the width L3 of second gap 2605 may vary. Therefore, it is necessary to compare the width L2 of first gap 2604 and the width L3 of second gap 2605 at the same height relative to the bottom wall of adhesive groove 2601 and calculate the difference between the width L2 of first gap 2604 and the width L3 of second gap 2605.

[0116] like Figure 10 and Figure 11 As shown, in the insertion direction of the shell 261 and the shell 262, the height of the end of the first gap 2604 away from the bottom wall relative to the bottom wall is greater than the height of the end of the second gap 2605 away from the bottom wall relative to the bottom wall.

[0117] Compared to the second gap 2605, the first gap 2604 has a larger width, and the glue tends to flow into the first gap 2604. By setting the height of the end of the first gap 2604 facing away from the bottom wall relative to the bottom wall to be greater than the height of the end of the second gap 2605 facing away from the bottom wall relative to the bottom wall, the first gap 2604 can accommodate more glue, thereby reducing the probability of glue flowing into the interior of the housing assembly 26 through the first gap 2604.

[0118] In some embodiments, combined Figure 10 and Figure 11 The height difference H2 between the end of the first gap 2604 away from the bottom wall and the end of the second gap 2605 away from the bottom wall is greater than or equal to 0.5 mm. For example, the height difference H2 between the end of the first gap 2604 away from the bottom wall and the end of the second gap 2605 away from the bottom wall can be 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm.

[0119] Such a configuration allows the first gap 2604 to accommodate more glue than the second gap 2605 during the process of inserting the second of the shells 261 and 262 into the glue holding groove 2601, so that the glue can flow more into the first gap 2064 during the squeezing process, while reducing the amount of glue flowing from the second gap 2604 to the interior of the shell assembly 26 within an acceptable range, or preventing the glue from flowing into the interior of the shell assembly 26.

[0120] like Figure 10 and Figure 11As shown, the adhesive containing groove 2601 includes a third sidewall 2607 connected to the first sidewall 2602. The third sidewall 2607 is farther from the bottom wall of the adhesive containing groove 2601 than the first sidewall 2602. A third gap 2608 is formed between the second of the housings 261 and 262 and the third sidewall 2607. In the spacing direction, the width of the third gap 2608 gradually increases in the direction away from the bottom wall. For example, the third sidewall 2607 is located in the housing 262 and forms the third gap 2608 with the housing 261.

[0121] When a large amount of glue flows into the second gap 2605 and overflows from the second gap 2605, the third gap 2608 can be used to accommodate the glue overflowing from the second gap 2605. By providing the third gap 2608, the risk of glue flowing from the second gap 2605 to the outer surfaces of the housing 261 and the housing 262 can be reduced.

[0122] In the spacing direction, by setting the width of the third gap 2608 to gradually increase in the direction away from the bottom wall of the glue holding groove 2601, the glue holding capacity of the third gap 2608 can be increased, further reducing the risk of glue flowing to the outer surfaces of the shell 261 and the shell 262.

[0123] Optionally, in the process of inserting the second one of the shells 261 and 262 into the glue groove 2601, the third side wall 2607 can also play a guiding role, facilitating the insertion of the second one of the shells 261 and 262 into the glue groove 2601, thereby improving assembly efficiency.

[0124] like Figure 10 and Figure 11 As shown, the width of part of the third gap 2608 may be greater than the width L2 of the first gap 2604 .

[0125] The width of the portion of third gap 2608 near the bottom wall of glue-receiving groove 2601 is smaller, reducing the amount of glue that can be accommodated by third gap 2608. By setting the width of the portion of third gap 2608 away from the bottom wall of glue-receiving groove 2601 to be greater than the width L2 of first gap 2604, the amount of glue that can be accommodated by third gap 2608 can be increased, reducing the risk of glue flowing onto the outer surfaces of housing 261 and housing 262.

[0126] like Figure 10 and Figure 11 As shown, the height of one end of the first gap 2604 away from the bottom wall of the glue containing groove 2601 relative to the bottom wall of the glue containing groove 2601 is greater than the height of one end of the third gap 2608 away from the bottom wall of the glue containing groove 2601 relative to the bottom wall of the glue containing groove 2601, that is, there is a height difference H3.

[0127] By setting the height of one end of the first gap 2604 away from the bottom wall of the glue containing groove 2601 relative to the bottom wall of the glue containing groove 2601 to be greater than the height of one end of the third gap 2608 away from the bottom wall of the glue containing groove 2601 relative to the bottom wall of the glue containing groove 2601, the first gap 2604 can accommodate more glue, thereby reducing the probability of glue flowing into the interior of the shell assembly 26.

[0128] On the other hand, the first side wall 2602 can play a limiting role. Specifically, the third gap 2608 can play a guiding role. When the second of the shells 261 and 262 is inserted into the glue groove 2601, the second of the shells 261 and 262 will move toward the first side wall 2602. By setting the height of the end of the first gap 2604 away from the bottom wall relative to the bottom wall to be greater than the height of the end of the third gap 2608 away from the bottom wall relative to the bottom wall, when the second of the shells 261 and 262 moves toward the first side wall 2602, the first side wall 2602 can play a limiting role, so that the second of the shells 261 and 262 can be smoothly inserted into the glue groove 2601, thereby improving assembly efficiency.

[0129] like Figure 10 and Figure 11 As shown, the shell assembly 26 may include an elastic coating 263 partially covering the outer surface of the shell 261, a glue groove 2601 is set on the shell 262, and the exposed part of the shell 261 not covered by the elastic coating 263 is inserted into the glue groove 2601.

[0130] Specifically, the exposed portion of the shell 261 that is not covered by the elastic coating 263 may be the connecting boss 2609 .

[0131] Providing an elastic coating 263 on the outer surface of the housing 261 can improve the comfort of the user when holding the earphone 100 and can also increase friction.

[0132] By inserting the exposed portion of the shell 261 into the glue groove 2601, the shell 261 can position the shell 262, limit the relative movement between the shell 261 and the shell 262, and improve the connection stability between the shell 261 and the shell 262.

[0133] By arranging the exposed portion of the shell 261 to be not covered by the elastic coating 263 , it is possible to prevent the elastic coating 263 from interfering with the connection between the shell 261 in the glue-containing groove 2601 and the shell 262 .

[0134] Furthermore, the shell 262 abuts against the elastic coating 263 along the exposed portion relative to the insertion direction of the shell 262, so that the outer surface of the shell 262 and the outer surface of the elastic coating 263 are flush at the abutment point. On the one hand, the shell 262 and the elastic coating 263 are tighter at the abutment point, which can achieve a better sealing effect, reduce the entry of debris and water vapor, and increase the service life of the elastic coating 263. On the other hand, being flush at the abutment point can reduce the discomfort caused to the user when being touched, making the earphone 100 more integrated and comfortable, and also making the earphone 100 more beautiful in appearance.

[0135] Furthermore, the shell 262 is not covered by the elastic coating 263 , and the outer surface area of ​​the shell 262 may be smaller than the outer surface area of ​​the shell 261 . Users tend to hold the shell 261 to hold the earphone 100 , so the elastic coating 263 may not be provided on the outer surface of the shell 262 .

[0136] like Figure 14 and Figure 15 As shown, the ear hook assembly 2 may include a housing assembly 20, an interface assembly 22, a retaining member 25, a circuit board 28, and a wire assembly 24. Optionally, the earphone 100 may further include a wearing assembly 30 and a dust plug 23.

[0137] Alternatively, as Figures 15 to 18 As shown, the housing assembly 20 includes a housing 201, which is provided with a receiving slot 2004 and a receiving cavity 2010 communicating with the receiving slot 2004. The interface assembly 22 is inserted into the receiving slot 2004. The circuit board 28 is disposed in the receiving cavity 2010. The wire assembly 24 electrically connects the circuit board 28 and the interface assembly 22.

[0138] By separating the interface assembly 22 and the circuit board 28, rather than directly soldering the interface assembly 22 to the circuit board 28, and instead connecting the interface assembly 22 and the circuit board 28 using a wire assembly 24, the interface assembly 22 can be installed in a more flexible position and posture. Furthermore, a receiving slot 2004 and a receiving cavity 2010 communicating with the receiving slot 2004 are strategically positioned within the housing 201 to accommodate the interface assembly 22 and the circuit board 28, respectively. This facilitates flexible use of the space within the housing 201, facilitating the separate installation of the interface assembly 22 and the circuit board 28, and easing assembly of the earphones 100, effectively reducing assembly difficulty.

[0139] Combine Figure 16 As shown, in the insertion direction f2 of the interface component 22 relative to the receiving groove 2004, the circuit board 28 maintains a certain distance from the interface component 22.

[0140] By maintaining a certain distance between the interface component 22 and the circuit board 28 in the insertion direction f2 of the interface component 22 relative to the accommodating groove 2004, the interface component 22 can effectively reduce the encroachment of the space of the accommodating cavity 2010 accommodating the circuit board 28, effectively reduce the possibility of the interface component 22 interfering with the circuit board 28, improve the effectiveness of the operation of the interface component 22 and the circuit board 28, and improve the reliability and service life of the earphones 100.

[0141] Alternatively, as Figures 16 to 19 As shown, the housing 201 is provided with an insertion slot 2001 separated from the receiving slot 2004 by a partition wall 2018, wherein the partition wall 2018 is provided with a connecting slot 2019 connecting the insertion slot 2001 and the receiving slot 2004. The wearing assembly 30 includes an inserting member 33, which includes an inserting body 331 inserted into the insertion slot 2001. The locking member 25 is configured to be inserted from the receiving slot 2004 through the connecting slot 2019 and is used to lock the inserting body 331 into the insertion slot 2001. The interface assembly 22 is inserted into the receiving slot 2004.

[0142] The partition wall 2018 is provided to form an isolated insertion slot 2001 and a receiving slot 2004, which are respectively used to accommodate the insertion member 33 and the interface assembly 22. While effectively limiting the installation of the insertion member 33 and the interface assembly 22, the insertion member 33 and the interface assembly 22 do not interfere with each other and do not occupy each other's space, facilitating assembly and disassembly, and facilitating the maintenance and care of the earphone 100. The connecting slot 2019 provided on the partition wall 2018 is used to accommodate the retaining member 25 to retain the insertion body 331 in the insertion slot 2001. The retaining member 25 retains the insertion body 331 in position without being exposed to the outside of the housing 201. This improves the stability and reliability of the installation of the insertion body 331 while maintaining the appearance of the earphone 100, effectively enhancing the aesthetics of the earphone 100. In addition, setting the connecting groove 2019 on the partition wall 2018 can improve the utilization of space, achieve a compact arrangement inside the shell assembly 20, and reduce the volume of the earphone 100.

[0143] Optionally, the rear end portion of the shell assembly 20 (i.e., the end portion where the notch of the receiving groove 2004 and the notch of the insertion groove 2001 are provided, which faces away from the ear when worn) is tilted. On the one hand, this is to reduce the volume and weight of the entire shell assembly 2 and miniaturize the entire earphone 100. On the other hand, it is easy to open the mold and demold in manufacturing, which reduces the manufacturing difficulty and makes the earphone 100 more beautiful. The interface assembly 22 is arranged at the rear end portion which is tilted, so that the slope area that is not easily utilized can be effectively utilized, making the overall structure more compact and the space utilization rate high. Moreover, the interface assembly 22 is arranged at the rear end portion instead of on the lower side, which has less impact on the placement stability of the earphone when in use. In addition, the wire connecting the interface assembly 22 is not likely to shake with the interface assembly 22 and cause unnecessary friction, and the wire is also not likely to rub against the area where it is placed.

[0144] Optionally, the interface assembly 22 and the housing 202 are fixed by dispensing glue to achieve fixation between the interface assembly 22 and the housing 202, as well as fixation and sealing between the connection points of the interface assembly 22 and the housing 202. Optionally, a silicone member (not shown) is provided between the interface assembly 22 and the housing 202, the silicone member having an interference fit with the interface assembly 22 and the housing 202, and the interface assembly 22 and the housing 202 are fixed by a fixing structure such as a snap screw, thereby achieving fixation between the interface assembly 22 and the housing 202, as well as fixation and sealing between the connection points of the interface assembly 22 and the housing 202.

[0145] Furthermore, if Figure 18 As shown, the position of the communication groove 2019 is set so that the locking member 25 is visible from the outside of the housing 201 along the insertion direction f3 of the locking member 25 relative to the communication groove 2019.

[0146] The connecting groove 2019 is visible from the outside of the shell 201, that is, the position of the connecting groove 2019 is clearly exposed to the outside of the shell 201, so that the position of the locking member 25 is clear and the operation is convenient when the locking member 25 is inserted along the insertion direction f3 relative to the connecting groove 2019, which effectively reduces the difficulty of assembly and facilitates assembly and disassembly.

[0147] Alternatively, as Figures 16 to 18 As shown, the housing assembly 20 further includes a housing 202 , which is connected to the housing 201 and is used to shield the communicating groove 2019 and the locking member 25 .

[0148] The connection between the housing 202 and the housing 201 conceals the connecting groove 2019 and the retaining member 25, preventing them from being visible from the outside of the earphone 100, thereby improving the aesthetics of the earphone 100. Compared to an integrated housing, the separately connected housing 201 and housing 202 allow the retaining member 25 to be installed when the housing 202 is not connected to the housing 201, which is convenient and easy to install. After the retaining member 25 is inserted, the connecting housing 202 and housing 201 conceal the connecting groove 2019 and the retaining member 25, ensuring both ease of assembly and aesthetics of the earphone 100.

[0149] Furthermore, if Figure 16 and Figure 19 As shown, the housing 202 is further configured to be able to stop the locking member 25 in the opposite direction of the insertion direction f3 of the locking member 25 relative to the communicating groove 2019.

[0150] While covering the connecting groove 2019 and the locking piece 25, the shell 202 can stop the locking piece 25 to provide support for the locking piece 25, thereby preventing the locking piece 25 from moving in the opposite direction of the insertion direction f3 of the locking piece 25 relative to the connecting groove 2019 during the use of the earphone 100, thereby causing the inserting piece 33 to loosen and affecting the use of the earphone 100, thereby improving the stability of the connection and increasing the service life of the earphone 100.

[0151] Alternatively, as Figure 18 and Figure 19 As shown, the interface assembly 22 includes a main body 221 and a cable assembly 222. The main body 221 is provided with a first guide cavity 2210, and the cable assembly 222 is disposed in the first guide cavity 2210. The housing 202 is provided with a second guide cavity 2022, and the housing 202 is connected to the housing 201, and the second guide cavity 2022 is connected to the first guide cavity 2210.

[0152] By connecting the shell 202 with the shell 201 so that the first guide cavity 2210 and the second guide cavity 2022 are docked, the interface assembly 22 does not need to set up a complete guide cavity for the wiring part 222, but uses the shell 202 to construct the second guide cavity 2022, which can reduce the overall volume of the shell assembly 20 and make the shell assembly 20 more compact.

[0153] The cable portion 222 protrudes from the first guide cavity 2210 and extends into the second guide cavity 2022. In this manner, the first guide cavity 2210 and the second guide cavity 2022 accommodate the cable portion 222, making it easier to connect the cable portion 222.

[0154] like Figure 19As shown, the interface assembly 22 may further include a flange portion 223, which is provided on a side of the main body 221 away from the accommodating cavity 2010. The housing 201 is provided with a first support surface 2015, on which the flange portion 223 is supported, and the housing 202 is configured to shield the flange portion 223.

[0155] By providing the flange portion 223 and the first support surface 2015, with the flange portion 223 supported on the first support surface 2015, the support provided by the first support surface 2015 on the flange portion 223 improves the stability and reliability of the installation of the interface assembly 22, effectively limiting the installation of the interface assembly 22. Furthermore, the housing 202 is configured to shield the flange portion 223, preventing it from being exposed outside the housing assembly 20. This prevents the user from seeing the flange portion 223 from outside the earphones 100, effectively improving the aesthetics of the earphones 100.

[0156] like Figure 19 As shown, the housing 202 can further press the flange portion 223 onto the first support surface 2015 .

[0157] The flange portion 223 is pressed by the shell 202 to press the flange portion 223 onto the first support table 2015, so that the flange portion 223 is tightly supported on the first support table 2015, thereby improving the supporting effect of the first support table 2015 on the flange portion 223, thereby making the limiting installation of the shell component 20 on the interface component 22 more stable and reliable, reducing the possibility of shaking of the interface component 22, and effectively improving the fixing effect.

[0158] like Figure 19 As shown, a glue containing groove 2016 is provided on the first supporting table 2015 , and the flange portion 223 covers the glue containing groove 2016 .

[0159] Glue groove 2016 can accommodate sealant, so that when the interface assembly 22 is installed, the sealant contained in the groove 2016 can fill the gap between the interface assembly 22 and the housing 201, improving the sealing performance. In addition, the use of sealant can effectively fix the interface assembly 22 and increase the stability of the connection between the interface assembly 22 and the housing 201.

[0160] like Figure 18 and Figure 19 As shown, the first supporting table 2015 , the flange portion 223 and the glue receiving groove 2016 are arranged to surround the receiving groove 2004 in a closed manner around the insertion direction f2 of the interface component 22 relative to the receiving groove 2004 .

[0161] The first support surface 2015, flange 223, and adhesive groove 2016 all enclose the receiving groove 2004 around the interface assembly 22. Specifically, the flange 223 surrounds the interface assembly 22 and is supported on the first support surface 2015. This effectively increases the contact area between the first support surface 2015 and the flange 223, and ensures that the support force provided by the first support surface 2015 to the interface assembly 22 is uniform and reliable. This effectively improves the support effect of the first support surface 2015 on the interface assembly 22, improves the fixing effect, and increases the service life of the earphone 100. In addition, the adhesive groove 2016 encloses the receiving groove 2004 around the interface assembly 22, allowing for complete adhesive dispensing around the receiving groove 2004 when the interface assembly 22 is installed, effectively improving the sealing effect.

[0162] Optionally, combined Figure 18 and Figure 19 The shell 201 is further provided with a second supporting surface 2017 , and the inner end surface of the main body 221 facing the accommodating cavity 2010 is supported on the second supporting surface 2017 .

[0163] By setting a second support table 2017 to support the inner end surface of the main body 221 facing the accommodating cavity 2010, the first support table 2015 and the second support table 2017 can jointly support the interface component 22, thereby improving the stability of the interface component 22 and further reducing the possibility of shaking of the interface component 22.

[0164] Alternatively, as Figure 20 and Figure 21 As shown, the locking member 25 includes two pins 251 arranged side by side and a connecting portion 252 connecting the two pins 251. The insertion body 331 is provided with two slots 335. The two pins 251 are respectively inserted into the two slots 335. The connecting portion 252 is arranged in the connecting groove 2019 and interferes with the groove wall of the connecting groove 2019 at least in the opposite direction of the insertion direction f1 of the insertion groove 2001 of the insertion body 331.

[0165] The locking member 25 is used to lock and limit the insertion body 331 to achieve the limited installation of the insertion member 33. By arranging two pins 251 side by side on the locking member 25, and the insertion body 331 is provided with two slots 335 that cooperate with the two pins 251 to connect the locking member 25 and the insertion body 331, the two pins 251 can be correspondingly inserted into the two slots 335. The simultaneous action of the two pins 251 can improve the stability of the connection and improve the locking effect.

[0166] The connecting portion 252 is arranged in the connecting groove 2019, and the connecting portion 252 interferes with the groove wall of the connecting groove 2019 at least in the opposite direction of the insertion direction f1 of the insertion main body 331 relative to the insertion groove 2001, so that the groove wall of the connecting groove 2019 provides supporting force to the connecting portion 252, thereby reducing the overall height of the locking member 25 and improving the stability and reliability of the connection.

[0167] like Figure 19 and Figure 21 As shown, the connecting portion 252 can be sunk into the communicating groove 2019 , and a glue containing groove 2023 communicating with the communicating groove 2019 can be provided on the shell 202 .

[0168] The adhesive groove 2023 can accommodate sealant. When the housing 202 is installed, the sealant contained in the adhesive groove 2023 can fill the gaps between the housing 202 and the connecting groove 2019 and the connecting portion 252, thereby improving the sealing performance. The use of sealant can also effectively fix the retaining member 25 and the housing 202, thereby increasing the stability of the connection between the housing 201, the housing 202, and the retaining member 25.

[0169] Alternatively, as Figure 19 As shown, the first support surface 2015 is further provided on the partition wall 2018. The flange portion 223 is supported on the first support surface 2015.

[0170] By providing the flange portion 223 and the support table 2015 , and the flange portion 223 being supported on the first support table 2015 , the support of the flange portion 223 by the support table 2015 can improve the stability and reliability of the installation of the interface component 22 , and effectively limit the installation of the interface component 22 .

[0171] like Figure 19 As shown, the flange portion 223 can be further configured to stop the locking member 25 in the opposite direction of the insertion direction f3 of the locking member 25 relative to the communicating groove 2019.

[0172] By setting the flange portion 223 to stop the locking member 25 in the opposite direction of the insertion direction f3 of the locking member 25 relative to the connecting groove 2019, further supporting force is provided for the locking member 25, and the locking member 25 is further stopped and limited, making the structure more stable and firm, further reducing the possibility of shaking or loosening of the locking member 25, and increasing the service life of the earphone 100.

[0173] Alternatively, as Figure 16As shown, the interface assembly 22 is positioned at an acute angle with respect to the insertion direction f2 of the receiving slot 2004 and the insertion direction f1 of the insert 33 with respect to the insertion slot 2001. Specifically, the insert body 331 is positioned at an acute angle with respect to the insertion direction f1 of the insertion slot 2001 and the insertion direction f2 of the interface assembly 22 with respect to the receiving slot 2004. The second support surface 2017 is positioned on the side of the interface assembly 22 facing away from the insert 33, while the inner end surface of the main body 221 is suspended in the air, facing the side of the insert 33.

[0174] On the basis that the insertion direction f2 of the interface component 22 relative to the accommodating groove 2004 and the insertion direction f1 of the insert 33 relative to the insertion groove 2001 are set at an acute angle, the inner end face of the main body 221 is supported on the second support table 2017 on the side facing away from the insert 33, and is suspended on the side facing the insert 33. While effectively supporting and fixing the interface component 22, the volume of the shell component 20 is reduced, thereby improving the space utilization inside the shell component 20.

[0175] Alternatively, as Figure 16 As shown, the side of the interface component 22 facing the interior of the housing 201 is arranged to extend beyond the partition wall 2018 in the insertion direction f2 of the interface component 22 relative to the accommodating groove 2004.

[0176] On the basis that the insertion direction f2 of the interface component 22 relative to the accommodating groove 2004 and the insertion direction f1 of the insertion part 33 relative to the insertion groove 2001 are set at an acute angle, the interface component 22 extends beyond the partition wall 2018, thereby further fully utilizing the space inside the shell component 20 without interfering with the insertion body 331, thereby improving the space utilization rate inside the shell component 20, making the structure inside the shell component 20 more compact, and improving the integration and tightness of the structure, thereby reducing the volume of the shell component 20, and then reducing the volume of the earphone 100, making the earphone 100 more convenient to wear and carry, and improving the usability of the earphone 100.

[0177] like Figures 22 to 24 As shown, the interface assembly 22 is inserted into the receiving slot 2004. The interface assembly 22 is used to connect to a corresponding external interface, allowing the headset 100 to be electrically connected to other devices for charging, data transmission, and other functions. The dust plug 23 can be partially fixed to the housing assembly 20 through the mutual cooperation of the housing 201 and the housing 202, and can selectively cover the interface assembly 22.

[0178] Optionally, the wearing component 30 may include an insert 33. The insert 33 may be inserted into the housing component 20 so that the wearing component 30 is fixed to the housing 201. The wearing component 30 is used to be worn on the auricle, neck, back of the head, etc. to fix the earphone 100 in a certain position.

[0179] Alternatively, as Figures 23 to 24 As shown, the earphone 100 further includes a button assembly 21 disposed in the housing 201 and exposed outside the housing 202 . Specifically, the button assembly 21 is used to be operated by the user to implement a human-computer interaction function with the earphone 100 .

[0180] Specifically, if Figures 23 to 24 As shown, the dust plug 23 may include a plug body 231 and a fixing portion 232. The fixing portion 232 may be positioned on the housing 201 by the housing 202. The plug body 231 is connected to the fixing portion 232 and is used to selectively shield the interface assembly 22.

[0181] The plug body 231 is movable relative to the interface assembly 22, thereby selectively covering or exposing the interface assembly 22. The fixing portion 232 is connected to the plug body 231 to pull the plug body 231, so that the plug body 231 can still be connected to the housing assembly 20 through the fixing portion 232 when the interface assembly 22 is exposed, thereby preventing the plug body 231 from falling off the earphone 100.

[0182] The dust plug 23 is provided to selectively shield the interface assembly 22. When the interface assembly 22 is not connected to a corresponding plug, the dust plug 23 can shield it, thereby preventing dust particles and other impurities from falling into the interface assembly 22 and clogging the interface assembly 22, thereby affecting the use of the interface assembly 22. The fixing portion 232 of the dust plug 23 is restrained on the housing 201 by the housing 202, and the dust plug 23 is then fixed by the housing 201 and the housing 202 together. This makes the assembly of the dust plug 23 more stable, eliminates the need for direct fixing to the housing 201, avoids the need for a corresponding fixing position on the housing 201, simplifies the structure of the housing 201 and the housing 202, and also simplifies the assembly method of the dust plug 23.

[0183] like Figures 23 to 28 As shown, the main body 221 can be provided with a first guide cavity 2210, the wiring portion 222 is provided in the first guide cavity 2210, the shell 202 is provided with a second guide cavity 2022, the second guide cavity 2022 is docked with the first guide cavity 2210, and the plug body 231 is configured to be able to be selectively inserted into or removed from the first guide cavity 2210.

[0184] Specifically, the main body 221 is used to connect to the external interface corresponding to the interface assembly 22. The cable portion 222 protrudes from the first guide cavity 2210 and extends into the second guide cavity 2022. The cable portion 222 is used to electrically connect the earphones 100 to an external device after the external interface is inserted. In this way, the first guide cavity 2210 and the second guide cavity 2022 both accommodate the cable portion 222, making it easier to connect the cable portion 222.

[0185] Optionally, the plug body 231 can be inserted into the first guide cavity 2210 through the second guide cavity 2022 to shield the interface assembly 22. The shape of the plug body 231 can be adapted to the first guide cavity 2210 and the cable routing portion 222, so that the cable routing portion 222 does not easily obstruct the insertion of the plug body 231 into the first guide cavity 2210. By providing the second guide cavity 2022 to interface with the first guide cavity 2210, the interface assembly 22 does not need to have a complete guide cavity, which can reduce the volume of the interface assembly 22 and, in turn, the volume of the entire housing assembly 20.

[0186] By docking the second guide cavity 2022 with the first guide cavity 2210, the interface assembly 22 can be pressed between the housing 201 and the housing 202, thereby improving the installation convenience of the interface assembly 22. Moreover, the insertion portion of the plug body 231 is configured to adapt to the second guide cavity 2022 and the first guide cavity 2210, so that the plug body 231 can be fixed relative to the interface assembly 22 after being inserted into the first guide cavity 2210, and is not likely to fall out of the first guide cavity 2210 and the second guide cavity 2022.

[0187] Optionally, when the plug body 231 is inserted into the first guide cavity 2210, the side thereof facing away from the interface assembly 22 can completely cover the second guide cavity 2022 to completely shield the interface assembly 22, so that impurities such as dust and metal particles are not easily dropped into the interface assembly 22.

[0188] Optionally, the plug body 231 may be an elastomer made of elastic materials such as silicone and rubber, thereby facilitating the selective insertion or removal of the plug body 231 into the first guide cavity 2210 without damaging the interface assembly 22 during the process.

[0189] By setting the second guide cavity 2022 and the first guide cavity 2210, the plug body 231 can be easily selectively inserted into or removed from the first guide cavity 2210, so that the plug body 231 can selectively cover the interface component 22, thereby reducing the occurrence of impurities such as dust and metal particles falling into the interface component 22.

[0190] Alternatively, as Figures 23 to 28 As shown, the inserting member 33 is inserted into the inserting slot 2001, and the fixing portion 232 is located on the side of the interface component 22 away from the inserting member 33. Figure 24 As shown, the fixing portion 232 and the insert 33 are respectively located on both sides of the interface assembly 22, so that the positions of the dust plug 23 and the insert 33 will not affect each other, and can save space in the earphone 100 and improve the space utilization of the earphone 100.

[0191] Optionally, the fixing portion 232 is located between the button assembly 21 and the interface assembly 22. Such a configuration can save the usage space of the headset 100, reduce the volume of the headset 100, and improve the space utilization of the headset 100.

[0192] In some embodiments, as Figures 24 to 29 As shown, the housing 202 can be connected to the housing 201, and the fixing portion 232 can be pressed and retained on the housing 201. Specifically, the housing 202 can cover the housing 201, and the fixing portion 232 can be partially disposed on the housing 201 and retained on the housing 201 under the pressure of the housing 202. This arrangement can make the assembly of the dust plug 23 more convenient and also facilitate the disassembly and maintenance of the earphone 100.

[0193] Alternatively, as Figure 25 As shown, a positioning hole 235 may be provided on the first of the fixing part 232 and the shell 201, and a positioning column 236 may be provided on the second of the fixing part 232 and the shell 201. The positioning column 236 is inserted into the positioning hole 235, and the shell 202 presses the fixing part 232 to be positioned on the shell 201 at the periphery of the positioning hole 235.

[0194] The positioning holes 235 and positioning posts 236 allow the fixing portion 232 to engage with the housing 201. The housing 202 then presses the positioning posts 236 against the positioning holes 235, securing the fixing portion 232 to the housing 201. This arrangement facilitates assembly and disassembly of the fixing portion 232, the housing 201, and the housing 202. It also makes the earphone 100 more compact, allowing the fixing portion 232 to be securely secured to the housing 201.

[0195] Optionally, the fixing portion 232 may be an elastic body, the positioning hole 235 may be provided on the fixing portion 232, the positioning post 236 may be provided on the housing 201, and the insertion depth of the positioning post 236 relative to the positioning hole 235 may be less than the hole depth of the positioning hole 235. Specifically, the positions of the positioning hole 235 on the fixing portion 232 and the positioning post 236 on the housing 201 may correspond to each other, the positioning post 236 is inserted into the positioning hole 235, and the extension direction of the positioning post 236 may be as follows: Figure 25 As shown by the arrow I in the middle, the housing 202 can be pressed toward the positioning post 236 in the extending direction of the positioning post 236 , so that the fixing portion 232 can be fixed to the housing 201 after the housing 201 and the housing 202 are relatively connected and fixed.

[0196] The fixing portion 232 may be made of an elastic material such as silicone or rubber. The insertion depth of the positioning hole 235 is smaller than the depth of the positioning hole 235, so that the fixing portion 232 has a certain amount of compression space in the extension direction of the positioning post 236 and can elastically deform under the pressure of the housing 202 and the housing 201, thereby being fixed and restrained by the housing 201 and the housing 202. This allows the fixing portion 232 to be more firmly restrained on the housing 201 and is less likely to loosen, thereby improving the structural tightness and stability of the earphone 100.

[0197] In other embodiments, Figures 26 to 27 As shown, the housing 202 can be connected to the housing 201, and the fixing portion 232 can be connected to the housing 202. The housing 202 and the housing 201 can be fixed to each other, and the fixing portion 232 can be connected to the housing 202 and can also be limited to the housing 201.

[0198] Alternatively, as Figure 27 As shown, a mounting hole 2021 may be provided on the shell 202, and the dust plug 23 may further include a connecting column 233 connected to the fixing portion 232 and a locking portion 234 connected to the connecting column 233, the connecting column 233 is inserted into the mounting hole 2021, and the fixing portion 232 and the locking portion 234 are respectively locked on both sides of the shell 202.

[0199] Specifically, one end of the fixing portion 232 can be connected to the plug body 231, and the end away from the plug body 231 is connected to the connecting post 233. The fixing portion 232 and the locking portion 234 are respectively provided at both ends of the connecting post 233. The plug body 231 is connected and fixed to the housing 202 via the fixing portion 232 and the locking portion 234. The locking portion 234 is located in the gap between the housing 202 and the housing 201, and can be blocked by the housing 202 and fixed relative to the housing 202 and the housing 201, thereby preventing the plug from moving toward the housing 202 and falling off the housing 202.

[0200] Optionally, the locking portion 234 is an elastic body and is configured to pass through the mounting hole 2021 under the action of external traction. Among them, the locking portion 234 can be an elastic body such as silicone or rubber, which can be elastically deformed under the action of external force and can return to its original shape after the external force is removed.

[0201] Based on the above description, the dust plug 23 may further include a pulling portion 237, which may be connected to the end of the locking portion 234 facing away from the connecting post 233. The pulling portion 237 is configured to be pulled and, under the action of an external pulling force, drive the locking portion 234 through the mounting hole 2021, thereby completing the assembly of the fixing portion 232. Furthermore, after passing through the mounting hole 2021, the locking portion 234 can be compressed within the gap between the housing 202 and the housing 201, thereby securing the housing 202 and the housing 201 relative to each other and preventing rotation or loosening. It also prevents the dust plug 23 from falling out of the mounting hole 2021. After the locking portion 234 passes through the mounting hole 2021 and is secured, the pulling portion 237 can be removed, for example, by shearing it off. This saves space within the housing 201 and improves the space utilization of the earphone 100.

[0202] By setting the locking portion 234 as an elastomer, the dust plug 23 can be easily assembled to simplify the assembly process of the earphone 100, and the dust plug 23 can be easily disassembled and repaired, while also making the connection structure of the earphone 100 tighter and more stable.

[0203] like Figures 28 to 31 As shown, the shell assembly 10 is provided with an insertion groove 1008. The wearing assembly 27 includes a wire assembly 271 and an insert 272, the insert 272 includes an insert body 2721 that can be inserted into the insertion groove 1008, the wire assembly 271 is inserted into the insert body 2721, and has an exposed portion 2711 exposed from the inner end surface of the insert body 2721 facing the inside of the shell assembly 10, wherein the insert 272 also includes an annular rib 2722 protruding from the inner end surface, the annular rib 2722 is arranged around the exposed portion 2711, so that the inner annular surface of the annular rib 2722 forms a first glue-containing groove 2723 on the periphery of the exposed portion 2711. The annular rib 2722 and the insert body 2721 can be integrally formed. The annular rib 2722 can also be considered as a part of the insert body 2721.

[0204] By filling the first glue groove 2723 with glue, the assembly gap between the wire assembly 271 and the insertion body 2721 is sealed to achieve a waterproof seal. Furthermore, because the first glue groove 2723 is formed by the inner annular surface of the annular rib 2722 around the outer periphery of the exposed portion 2711 of the wire assembly 271, the connection between the wire assembly 271 and the insertion body 2721 can be tightened, improving the stability of the connection between the wire assembly 271 and the insertion body 2721.

[0205] See Figures 28 to 33Optionally, the outer annular surface of the annular rib 2722 cooperates with the groove wall to form a second glue-receiving groove 2724. The second glue-receiving groove 2724 contains glue for the assembly gap between the housing assembly 10 and the insertion body 2721, thereby providing a corresponding waterproof seal. Furthermore, by filling the second glue-receiving groove 2724 with glue, the connection between the housing assembly 10 and the insertion body 2721 can be further tightened, preventing the insertion body 2721 from shaking in the housing assembly 10.

[0206] In some embodiments, the second glue-containing groove 2724 is arranged in a ring shape around the annular rib 2722, so that the sealant can achieve a more comprehensive ring-shaped seal around the annular rib 2722, thereby reducing the entry of water vapor and the like into the shell assembly 10 from the gap between the insertion body 2721 and the groove wall of the insertion groove 1008.

[0207] See Figures 28 to 32 Optionally, in the insertion direction of the insert 272 relative to the insertion slot 1008, the depth of the first glue groove 2723 is greater than the depth of the second glue groove 2724, so that the first glue groove 2723 can accommodate more glue, thereby improving the fixing effect and sealing effect of the wire assembly 271, and the shallower second glue groove 2724 can enable the insertion body 2721 to have more area with the insertion slot 1008, thereby improving the insertion and fixing effect, and the glue in the second glue groove 2724 can also have a good sealing effect.

[0208] In some embodiments, as Figure 31 As shown, the outer ring surface of the annular rib 2722 includes a first sub-outer ring surface 2725, a connecting surface 2726 and a second sub-outer ring surface 2728. The first sub-outer ring surface 2725 is closer to the interior of the shell assembly 10 than the second sub-outer ring surface 2728. The gap between the first sub-outer ring surface 2725 and the groove wall is larger than the gap between the second sub-outer ring surface 2728 and the groove wall. The connecting surface 2726 is connected to the first sub-outer ring surface 2725 and the second sub-outer ring surface 2728. The first sub-outer ring surface 2725, the connecting surface 2726 and the groove wall of the insertion groove 1008 cooperate to form a second glue-containing groove 2724.

[0209] See Figures 28 to 33 In some embodiments, in a direction perpendicular to the insertion direction of the insert 272 relative to the insertion groove 1008 , a width H4 of the first glue containing groove 2723 is greater than a width H5 of the second glue containing groove 2724 . Figure 33The width H5 shown is only marked on the annular rib 2722, but should be understood as the distance between the first sub-outer annular surface 2725 of the annular rib 2722 and the corresponding groove wall of the insertion groove 1008. This configuration allows, on the one hand, the first glue-receiving groove 2723 to accommodate more glue, thereby improving the fixation and sealing effect on the wire assembly 271. On the other hand, less glue can be used to meet the sealing requirements of the second glue-receiving groove 2724. Furthermore, because the width H5 of the second glue-receiving groove 2724 is less than the width H4 of the first glue-receiving groove 2723, the distance between the outer annular surface of the annular rib 2722 and the groove wall can be shortened, which can increase the glue application pressure in the second glue-receiving groove 2724, allowing the sealant in the second glue-receiving groove 2724 to further enter the gap between the outer annular surface of the annular rib 2722 and the groove wall.

[0210] See Figure 29 and Figure 30 In some embodiments, the shell assembly 10 is provided with a accommodating cavity 1001, which is communicated with the insertion groove 1008. The shell assembly 10 includes a limiting member 1009 located between the accommodating cavity 1001 and the insertion groove 1008. The limiting member 1009 is used to abut the insertion body 2721, specifically, it can abut the annular rib 2722 to limit the insertion depth of the insertion body 2721 relative to the insertion groove 1008.

[0211] See Figures 30 to 31 In some embodiments, when viewed from one side of the accommodating cavity 1001, at least a portion of the first glue containing groove 2723 and / or the second glue containing groove 2724 is not blocked by the limiting member 1009, making it easier to apply sealant to the first glue containing groove 2723 and the second glue containing groove 2724. For example, at least a portion of the first glue containing groove 2723 is not blocked by the limiting member 1009. For another example, at least a portion of the second glue containing groove 2724 is not blocked by the limiting member 1009. For another example, at least a portion of the first glue containing groove 2723 and a portion of the second glue containing groove 2724 are not blocked by the limiting member 1009. In this way, it can be ensured that the glue is filled from the side of the first glue containing groove 2723 and / or the second glue containing groove 2724 that is not blocked by the limiting member 1009.

[0212] See Figure 29 and Figure 30 In some embodiments, when observed from one side of the accommodating cavity 1001, the area of ​​the first glue containing groove 2723 blocked by the limiting member 1009 is smaller than the area of ​​the area not blocked by the limiting member 1009, and / or the area of ​​the second glue containing groove 2724 blocked by the limiting member 1009 is smaller than the area of ​​the area not blocked by the limiting member 1009.

[0213] Since the area blocked by the limiting member 1009 is smaller than the area not blocked by the limiting member 1009 , the area available for glue application can be effectively increased, further improving the efficiency of glue application.

[0214] See Figure 29 and Figure 30 In some embodiments, the opening of the first glue receiving groove 2723 in the area not blocked by the stopper 1009 is closer to the accommodating cavity 1001 than the opening of the area blocked by the stopper 1009, and / or the opening of the second glue receiving groove 2724 in the area not blocked by the stopper 1009 is closer to the accommodating cavity 1001 than the opening of the area blocked by the stopper 1009. This further facilitates the application of glue and improves the probability of glue application.

[0215] In some embodiments, in the direction from the side not blocked by the limiting member 1009 to the side blocked by the limiting member 1009, the bottom of the first glue containing groove 2723 is inclined toward a direction away from the accommodating cavity 1001, and / or the bottom of the second glue containing groove 2724 is inclined toward a direction away from the accommodating cavity 1001, so as to facilitate the glue to flow along the bottom of the groove from the side not blocked by the limiting member 1009 to the side blocked by the limiting member 1009, thereby improving the glue application efficiency.

[0216] See Figure 29 In some embodiments, the wearing component 27 further includes an elastic metal wire 273 and a covering 274. The elastic metal wire 273 and the wire assembly 271 are configured to penetrate the insertion body 2721 from the outer end surface of the insertion body 2721 facing away from the interior of the shell assembly 10. The covering 274 is configured to cover the side of the insertion body 2721 facing away from the interior of the shell assembly 10 along the circumference of the insertion body 2721, and expose the side of the insertion body 2721 facing the interior of the shell assembly 10.

[0217] See Figure 29 and Figure 30 The covering member 274 circumferentially covers the insertion body 2721 that is not inserted into the insertion slot 1008. The covering member 274 can be a rubber member or a silicone member. This can provide waterproofing, protect the elastic wire 273 and the wire assembly 271 that are not inserted into the housing assembly 10, and the insertion body 2721, and improve the appearance quality of the earphone 100.

[0218] The above content mainly describes the core component 1 and the ear hook component 2, and the following content mainly describes the structure of the back hanging component 3 and other parts of the earphone 100.

[0219] like Figure 34As shown, the rear hanging component 3 includes a wearing component 30. The wearing component 30 may include an elastic metal wire 31, a wire component 32, an insert 33 and a covering component 34.

[0220] Optionally, the elastic metal wire 31 may be made of titanium alloy, or other metals or alloys that can provide elasticity, which is not limited here. The insert 33 is fixed to the end of the elastic metal wire 31 .

[0221] Optionally, the insert 33 further includes an insert body 331, and the conductor assembly 32 has an exposed portion 320 that extends from the main body covering portion 341 to the insert body 331. Optionally, the covering assembly 34 includes a main body covering portion 341 and an extended covering portion 342. The main body covering portion 341 is used to cover the elastic metal wire 31 and the outer periphery of the conductor assembly 32. The extended covering portion 342 is used to cover the outer periphery of the exposed portion 320 of the conductor assembly 32, and the extended covering portion 342 partially covers the insert body 331 along its circumference.

[0222] The inventors of the present application have discovered in long-term research that after the above-mentioned wearing component 30 is connected and matched with the shell components 20, 26, etc., glue can be further applied for fixation, and the glue often directly contacts the wire component 32. Since the adhesion between the plastic material (for example, Teflon) on the outer surface of the wire component 32 and the glue is not good, on the one hand, it will lead to unstable fixing effect, and on the other hand, the sealing between the plug-in structure and the shell component 20 / 26 is also poor. Also, because the wire component 32 is relatively soft, the yield rate of the connection and matching between the wearing component 30 and the shell component 20, 26 is low. Therefore, by adding an extension coating portion 342 to protect the exposed portion 320, the glue does not need to directly contact the exposed portion of the wire component 32, and the adhesion effect with the glue can be enhanced through the extension coating portion 342, thereby improving the fixing effect and sealing effect, and also improving the installation yield rate of the wearing component 30. Furthermore, the extension covering portion 342 partially covers the insertion body 331 in the circumferential direction of the insertion body 331 , so that the insertion body 331 is partially exposed in the circumferential direction to ensure the structural strength during plug-in mating.

[0223] like Figure 35 As shown, optionally, the thickness D20 of the epitaxial covering portion 342 is smaller than the thickness D21 of the main covering portion 341 , and the epitaxial covering portion 342 is connected to the main covering portion 341 to form a step structure.

[0224] Optionally, the extension covering portion 342 is integrally formed with the main covering portion 341. Specifically, the extension covering portion 342 and the main covering portion 341 are integrally formed by injection molding, compression molding, or the like. Of course, the extension covering portion 342 can also be provided separately from the main covering portion 341. For example, the extension covering portion 342 can be pre-formed into a tubular shape and fitted around the outer periphery of the exposed portion 320.

[0225] Optionally, a receiving groove 332 is provided on the surface of the insertion body 331, wherein the receiving groove 332 has an opening 333 in a cross section perpendicular to the insertion direction cz of the insertion body 331. The exposed portion 320 is provided within the receiving groove 332, and the extension covering portion 342 is integrally formed with the main body covering portion 341. When viewed from the opening direction of the opening 333 of the receiving groove 332, at least a portion of the exposed portion 320 located within the receiving groove 332 has an externally visible area, and the externally visible area is covered by the extension covering portion 342. Furthermore, the length direction of the receiving groove 332 is provided along the insertion direction cz. It can be understood that the length direction of the receiving groove 332 is the same as the insertion direction cz.

[0226] Optionally, the extension covering portion 342 fills the gap between the exposed portion 320 and the wall of the receiving groove 332 .

[0227] Alternatively, as Figure 35 and Figure 40 As shown, the cover assembly 34 further includes an extended insertion portion 343 integrally formed with the main body cover portion 341. The extended insertion portion 343 contacts the end surface of the insertion body 331 facing the main body cover portion 341. The extended insertion portion 343 can be inserted into the insertion slot 2001 of the housing assembly 20 along with the insertion body 331. The provision of the extended insertion portion 343 can increase the insertion depth of the insertion body 331, thereby improving structural stability.

[0228] like Figure 36 As shown, the insert 33 further includes an extension positioning portion 334 protruding from the end surface of the insert body 331, and the extension positioning portion 334 is embedded in the extension insert portion 343. By arranging the extension positioning portion 334 to be embedded in the extension insert portion 343, the contact interface area between the insert body 331 and the covering component 34 is increased, thereby improving the stability between the insert 33 and the covering component 34.

[0229] In other embodiments, when the extended insertion portion 343 is not provided, the extended positioning portion 334 protrudes from the end face of the insertion body 331 facing the main body covering portion 341, and the extended positioning portion 334 is embedded in the main body covering portion 341, which can also increase the area of ​​the contact interface between the insertion body 331 and the covering component 34.

[0230] Optionally, the elastic metal wire 31 is passed through the extended positioning portion 334 to improve the fixing effect between the elastic metal wire 31 and the insert 33 .

[0231] Alternatively, as Figure 35 As shown, in a cross section perpendicular to the insertion direction cz of the insertion body 331, the insertion body 331 has a length direction G2 and a width direction G3. The exposed portion 320 and the elastic wire 31 can be spaced apart along the width direction G3. By arranging the exposed portion 320 and the elastic wire 31 along the width direction G3 of the insertion body 331, the workability of the insertion piece 33 is improved.

[0232] like Figure 37 As shown, in other embodiments, the exposed portion 320 and the elastic wire 31 are spaced apart along the length direction G2. Since the insertion body 331 has a relatively limited size in the width direction G3, the exposed portion 320 and the elastic wire 31 are spaced apart along the length direction G2 of the insertion body 331 to improve the space utilization of the connector 33.

[0233] like Figure 36 As shown, the insertion body 331 is provided with two slots 335 arranged at intervals along the length direction G2 , and the exposed portion 320 and the elastic metal wire 31 are located between the two slots 335 in the length direction G2 .

[0234] Optionally, the width of the extension covering portion 342 covering the insertion body 331 in the circumferential direction of the insertion body 331 is less than or equal to one-quarter of the maximum circumferential length of the insertion body 331. The maximum circumferential length is the maximum circumference of the insertion body 331 on a reference plane perpendicular to the insertion direction cz without covering the exposed portion 320 and the extension covering portion.

[0235] The housing assembly 20 of the earhook assembly 2 is provided with an insertion slot 2001. The aforementioned extension coating portion 342 and extension insertion portion 343 are inserted into the insertion slot 2001 along with the insertion body 331. Furthermore, the earhook assembly 100 includes a sealant (not shown) for sealing the gap between the insertion body 331 and the extension coating portion 342 and the walls of the insertion slot 2001. The sealant wets the surface of the extension coating portion 342 more than the surface of the wire assembly 32.

[0236] like Figure 38As shown, the wire assembly 32 includes a wire body 321 and an insulating coating 322 surrounding the outer periphery of the wire body 321. Optionally, the insulating coating 322 is made of polytetrafluoroethylene, and the outer coating 342 is made of silicone. The sealant has a greater degree of wettability on the surface of the outer coating 342 than the sealant 2002 does on the surface of the insulating coating 322. This arrangement improves the bonding between the sealant and the outer coating 342, effectively enhancing the sealing and fixing effects, and thereby ensuring that the earphone 100 has a good waterproof effect.

[0237] An exemplary structure of the wearing assembly 30 is described above. Another exemplary structure of the wearing assembly 30 is described below.

[0238] like Figure 39 As shown, the wearing assembly 30 can specifically include an elastic metal wire 31, a wire assembly 32, an insert 33, and a covering assembly 34'. The insert 33 is fixed to the end of the elastic metal wire 31. The insert 33 also includes an insert body 331. The covering assembly 34' includes a main body covering portion 341', which is used to cover the outer periphery of the elastic metal wire 31 and the wire assembly 32. The wire assembly 32 has an exposed portion 320 exposed from the main body covering portion 341' and extending to the insert body 331.

[0239] like Figure 40 As shown, the insertion body 331 is provided with a channel 336. The exposed portion 320 of the wire assembly 32 is passed through the channel 336. For example, the channel 336 on the insertion body 331 can be pre-formed, and the exposed portion 320 is subsequently inserted into and passed through the channel 336.

[0240] By adding a channel 336 to the insert body 331 to protect the exposed portion 320, the glue can be bonded to the insert body 331 without directly contacting the exposed portion of the wire assembly 32. This enhances the adhesive effect, thereby improving the fixing and sealing effects, and improving the installation yield of the wearable assembly 30. Furthermore, by being arranged in the channel 336 to surround the exposed portion 320, the insert body 331 can better protect the wire assembly 32.

[0241] Optionally, the hole wall of the channel 336 is closed along the circumference of the exposed portion 320 and surrounds the outer periphery of the exposed portion 320 .

[0242] Alternatively, as Figure 39As shown, the covering assembly 34' also includes an extension covering portion 342' integrally formed with the main covering portion 341', and the extension covering portion 342' covers the insertion body 331 along the circumference of the insertion body 331 at one end facing the main covering portion 341', and exposes the other end of the insertion body 331 away from the main covering portion 341', thereby improving the waterproof effect of the end face of the insertion body 331 facing the main covering portion 341'.

[0243] In the insertion direction cz of the insertion body 331 , the covering length L6 of the extension covering portion 342 ′ covering the insertion body 331 is between 0.2 mm and 2.0 mm.

[0244] Referring to the above embodiment, optionally, the insert 33 further includes an extension positioning portion 334 (the extension positioning portion 334 can refer to Figure 36 The extension positioning portion 334 protrudes from the end surface of the insertion body 331 facing the main body covering portion 341', and the extension positioning portion 334 is embedded in the main body covering portion 341'. Similarly, the elastic metal wire 31 is provided in the extension positioning portion 334.

[0245] Referring to the above embodiment, in a cross-section perpendicular to the insertion direction cz of the insertion body 331 relative to the insertion slot 2001, the insertion body 331 has a length direction G2 and a width direction G3. Optionally, the exposed portion 320 and the elastic wire 31 can be spaced apart along the length direction G2, or they can be spaced apart along the width direction G3. By arranging the exposed portion 320 and the elastic wire 31 spaced apart along the width direction G3 of the insertion body 331, the workability of the insertion member 33 is improved. Of course, the arrangement of the exposed portion 320 and the elastic wire 31, as well as the arrangement of the slot, can refer to the above embodiment. The housing assembly 20 of the earhook assembly 2 is provided with an insertion slot 2001. The extended covering portion 342' and the channel 336 described above are inserted into the insertion slot 2001 along with the insertion body 331.

[0246] Optionally, the earphone 100 further includes a sealant (not shown), which is used to seal the gap between the insertion body 331 and the groove wall of the insertion groove 2001, wherein the wettability of the sealant on the surface of the insertion body 331 is greater than the wettability of the sealant on the surface of the wire assembly 32.

[0247] like Figure 38 As shown, the wire assembly 32 includes a wire body 321 and an insulating coating 322 covering the outer periphery of the wire body 321 , and the wettability of the sealant on the surface of the extension coating 342 is greater than the wettability of the sealant on the surface of the insulating coating 322 .

[0248] Optionally, the insulating coating 322 may be made of polytetrafluoroethylene, and the insert body 331 may be made of metal. The extended cladding portion 342 may be made of silicone. Alternatively, the insert body 331 may be made of any combination of one or more metals or alloys, without limitation. By making the insulating coating of high-temperature-resistant and insulating polytetrafluoroethylene, the insulating coating is prevented from melting when the conductor body generates excessive heat.

[0249] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
