[0044] The function box assembly of the headset usually includes a control box assembly and a battery box assembly. One end of the function box assembly is connected to the ear hook, and the other end is connected to the back hook. At present, the anti-slip part that fixes the two parts (the function box assembly and the ear hook, or the function box assembly and the back hook) is usually set on the outside of the function box. The anti-slip part extends from the outside of the function box into the inside of the function box to fix the function box assembly and the back hook, and / or the function box assembly and the ear hook. At this time, there will be a certain gap between the anti-slip part and the function box, and external liquid can easily enter the function box from the gap, which will affect the normal operation of the mainboard compartment in the function box. In order to solve this problem, the embodiment of the present application provides a connection structure 10( Figure 2 As shown), earphones 100 ( Figure 1 shown) and earphone system 1000 ( Figure 6 shown).

[0045] See also Figure 1 The earphone 100 of the embodiment of the present application includes a connecting structure 10. In some embodiments, the earphone 100 includes a bone conduction earphone 100 or an air conduction earphone 100.

[0046] Bone conduction earphones 100 use human bones as a medium, converting sound into mechanical vibrations. These mechanical vibrations transmit sound waves through the bones, allowing the user to hear the sound. Since the sound of bone conduction earphones 100 acts on the bones, long-term use will not significantly affect the user's eardrum, effectively protecting the user's hearing. Air conduction earphones 100 transmit sound through air vibrations, offering superior sound quality and penetration. The earphones 100 of this application will be described using bone conduction earphones 100 as an example.

[0047] See also Figure 2 and Figure 3The connection structure 10 of the embodiment of the present application includes a function box 11, a part to be connected 13 and an anti-slip part 15. The function box 11 includes a box body 111 and a cover body 113. The cover body 113 is installed on the box body 111 and together with the box body 111, a mounting cavity 115 is formed. At least one end of the box body 111 is provided with a connecting portion 1111. The connecting portion 1111 is provided with a through plug hole 1113. The plug hole 1113 is used to connect the outside with the mounting cavity 115. The part to be connected 13 is connected to the function box 11, and the plug hole 1113 is used for inserting the part to be connected 13. The anti-slip part 15 is located in the mounting cavity 115. The anti-slip part 15 is used to connect the function box 11 and the part to be connected 13, so that the function box 11 and the part to be connected 13 are fixedly connected.

[0048] Specifically, please combine Figure 1 In some embodiments, the function box 11 includes a battery box 117 for placing batteries and / or a control box 119 with control functions. In some embodiments, the function box 11 includes a control box 119. The control box 119 can be used to control the power on and off of the headset 100 and adjust the volume of the headset 100. In some embodiments, the function box 11 includes a battery box 117. The battery box 117 is used to load batteries, and the batteries are used to power the headset 100 so that the headset 100 can operate normally. The function box 11 of the present application may include a battery box 117 and a control box 119.

[0049] See also Figure 3 The mounting cavity 115 is used to accommodate components such as the battery and circuit board of the headset 100. The case 111 and the cover 113 are detachably connected. When the cover 113 is removed from the case 111, the battery and circuit board of the headset 100 can be easily installed in the mounting cavity 115, which also facilitates the repair and replacement of the battery and circuit board of the headset 100. When the cover 113 is installed in the case 111, the case 111 and the cover 113 can jointly protect the components inside the mounting cavity 115, effectively preventing the risk of external dust and moisture from entering the mounting cavity 115 and damaging the components inside the mounting cavity 115.

[0050] In some embodiments, the cover 113 and the box body 111 are connected by bonding. Preferably, the cover 113 and the box body 111 are bonded together using waterproof glue. In this case, the connection between the box body 111 and the cover 113 is relatively stable, the cover 113 is not likely to fall off relative to the box body 111, and the waterproof effect between the box body 111 and the cover 113 is good, and external liquid is not likely to enter the installation cavity 115 through the gap between the box body 111 and the cover 113. In the case where the earphone 100 is a swimming earphone 100, when the earphone 100 is working underwater, external water is not likely to enter the installation cavity 115 through the gap between the box body 111 and the cover 113, which can effectively prevent external liquid from affecting the normal operation of the components in the installation cavity 115. The waterproof glue can be, but is not limited to, polyurethane waterproof glue, nano-silicone waterproof glue, acrylate waterproof glue, or ethylene-vinyl acetate copolymer waterproof glue.

[0051] See also Figure 3 and Figure 4 The connecting member 13 is used to extend into the plug hole 1113 to connect with the function box 11. In some embodiments, the connecting member 13 includes an ear hook 137 of the earphone 100 and / or a back hook 139 of the earphone 100. When the user wears the earphone 100, the back hook 139 of the earphone 100 is worn on the head, and the ear hook 137 of the earphone 100 is worn behind the ear, thereby improving the wearing stability of the earphone 100 and preventing the earphone 100 from falling off when the user is outdoors or exercising. The back hook 139 is used to connect the battery box 117 and the control box 119. The earphone 100 also includes a transducer component 30, and the ear hook 137 is used to connect the battery box 117 and the transducer component 30, and to connect the control box 119 and the transducer component 30. The transducer component 30 is used to fit against the human skin. When the earphone 100 is in use, the transducer component 30 can vibrate mechanically to enable the user to hear sound.

[0052] In the case where the component 13 to be connected is the ear hook 137 of the headset 100 or the back hook 139 of the headset 100, a connecting portion 1111 is provided at one end of the box body 111 in the longitudinal direction X of the function box 11. The connecting portion 1111 is used to connect to the component 13 to be connected so that the function box 11 and the component 13 to be connected can be firmly connected. In the case where the component 13 to be connected includes the ear hook 137 of the headset 100 and the back hook 139 of the headset 100, the ear hook 137 and the back hook 139 are respectively connected to opposite ends of the function box 11 in the longitudinal direction X of the function box 11. In this case, the box body 111 is provided with connecting portions 1111 at both opposite ends of the function box 11 in the longitudinal direction X.

[0053] See also Figure 3 and Figure 4, the anti-slip part 15 is located in the installation cavity 115 and is connected to the connecting portion 1111. The anti-slip portion is used to make the connection between the function box 11 and the part to be connected 13 more stable, which can effectively avoid the problem of the part to be connected 13 falling off relative to the function box 11. The anti-slip part 15 in the current connection structure 10 usually extends into the installation cavity 115 from the outside of the function box 11 to connect the function box 11 and the part to be connected 13. In order to enhance the waterproof function of the connection structure 10, the outer surface of the function box 11 will be provided with a rubber bag. The rubber bag will increase the cost of the connection structure 10 and affect the overall appearance of the connection structure 10. The anti-slip part 15 of the present application is arranged in the installation cavity 115, so there is no need to open a hole in the surface of the function box 11 to install the anti-slip part 15. External liquid is not easy to enter the installation cavity 115, which can effectively avoid the problem of external liquid affecting the normal operation of the components in the installation cavity 115. Furthermore, the functional box 11 of the present application does not need to be coated with glue on the surface, which can save the material cost of the connection structure 10 and simplify the installation steps of the connection structure 10. In addition, the functional box 11 is more aesthetically pleasing.

[0054] In the connection structure 10 of the embodiment of the present application, the part to be connected 13 extends into the plug hole 1113 to be connected with the function box 11. The anti-slip part 15 is located in the installation cavity 115. The anti-slip part 15 is used to further firmly connect the function box 11 and the part to be connected 13, which can effectively prevent the part to be connected 13 from falling off relative to the function box 11. Compared with the current connection structure 10, in the connection structure 10 of the present application, the anti-slip part 15 can firmly connect the function box 11 and the part to be connected 13 without passing through the function box 11, and external liquid will not enter the installation cavity 115 from the gap between the anti-slip part 15 and the function box 11. The waterproof effect of the connection structure 10 is better, which can effectively prevent external liquid from entering the installation cavity 115 and affecting the normal operation of the mainboard compartment in the function box 11.

[0055] The connection structure 10 will be further described below with reference to the accompanying drawings.

[0056] See also Figure 3 and Figure 4 In some embodiments, the connecting portion 1111 is further provided with a connecting hole 1115, which is located in the installation cavity 115 and communicates with the plug hole 1113. The part to be connected 13 is provided with a matching hole 131, which corresponds to the connecting hole 1115. The anti-slip part 15 is penetrated by the connecting hole 1115 and the matching hole 131 to connect the functional box 11 with the part to be connected 13.

[0057] The connecting hole 1115 is provided on the side wall of the connecting portion 1111. The anti-slip member 15 of this embodiment can be a screw or a screw. At this time, during the installation process of the connecting structure 10, the cover body 113 can be separated from the box body 111 first, and when the part 13 to be connected enters the connecting portion 1111 through the plug hole 1113, and the connecting hole 1115 corresponds to the matching hole 131, the anti-slip member 15 can be sequentially extended into the connecting hole 1115 and the matching hole 131, so that the functional box 11 and the part 13 to be connected are firmly connected, and the anti-slip member 15 can effectively prevent the part 13 to be connected from moving in the direction away from the functional box 11. After the anti-slip member 15 is extended into the connecting hole 1115 and the matching hole 131, the cover body 113 can be bonded to the box body 111 by waterproof glue, so that the waterproof effect of the connecting structure 10 is better, and external liquid is not easy to enter the installation cavity 115.

[0058] A connecting hole 1115 and a matching hole 131 are provided in the anti-detachment portion so that when the function box 11 is connected to the part to be connected 13, the connection method between the function box 11 and the part to be connected 13 is relatively simple, and only holes need to be opened on the function box 11 and the part to be connected 13. The structure of the function box 11 and the part to be connected 13 is relatively simple, the processing is relatively simple, and the connection between the function box 11 and the part to be connected 13 is also relatively stable.

[0059] See also Figure 3 and Figure 4 In some embodiments, the extending direction of the connection hole 1115 is different from the extending direction of the plug hole 1113. In this case, the extending direction of the connection hole 1115 intersects with the extending direction of the plug hole 1113. For example, the angle between the extending direction of the connection hole 1115 and the extending direction of the plug hole 1113 can be 30°, 50°, 65°, or 90°.

[0060] The extending direction of the matching hole 131 is the same as the extending direction of the connecting hole 1115, so that the anti-slip member 15 can be easily inserted into the connecting hole 1115 and the matching hole 131. The extending direction of the plug hole 1113 is the direction in which the connected member 13 extends into the connecting portion 1111, and the extending direction of the connecting hole 1115 and the extending direction of the matching hole 131 are the directions in which the anti-slip member 15 is inserted into the connecting portion 1111 and the connected member 13. When the direction in which the connected member 13 extends into the connecting portion 1111 is different from the direction in which the anti-slip member 15 is inserted into the connecting portion 1111, the anti-slip member 15 can lock the function box 11 and the connected member 13, effectively preventing the connected member 13 from moving away from the connecting portion 1111. When the user uses the earphone 100, the ear hook 137 and / or the back hook 139 are not easy to fall off relative to the function box 11.

[0061] See also Figure 3 and Figure 4Preferably, in some embodiments, the extending direction of the connecting hole 1115 is perpendicular to the extending direction of the plug hole 1113, that is, the angle between the extending direction of the connecting hole 1115 and the extending direction of the plug hole 1113 is 90 degrees. In this case, the anti-drop member 15 can further stabilize the connection between the functional box 11 and the to-be-connected component 13, further effectively preventing the to-be-connected component 13 from moving away from the connecting portion 1111, and the processing of the connecting hole 1115 and the plug hole 1113 is also relatively simple.

[0062] In the case where the extending direction of the connecting hole 1115 is perpendicular to the extending direction of the plug hole 1113, in some embodiments, the plug hole 1113 passes through the two opposite side walls of the connecting portion 1111, and the connecting hole 1115 passes through the top wall of the connecting portion 1111, and the two ends of the top wall connect the two side walls. The connecting portion 1111 includes two opposite side walls in the length direction X of the function box 11, and the connecting portion 1111 includes two opposite top walls in the thickness direction Y of the function box 11. The to-be-connected member 13 extends into the plug hole 1113 along the length direction X of the function box 11, and the anti-slip member 15 is provided with the connecting hole 1115 and the matching hole 131 along the thickness direction Y of the function box 11, so that the function box 11 is fixedly connected to the to-be-connected member 13.

[0063] See also Figure 3 and Figure 4 In other embodiments, at least a portion of the component to be connected 13 extends into the installation cavity 115, and the anti-slip member 15 is provided at one end of the component to be connected 13 located within the installation cavity 115. The anti-slip member 15 cooperates with the side wall of the connecting portion 1111 to connect the functional box 11 to the component to be connected 13. Specifically, in some embodiments, the anti-slip member 15 is a hook that snaps into engagement with the side wall of the connecting portion 1111.

[0064] Wherein, the anti-slip part 15 is connected to one end of the part to be connected 13. At this time, the anti-slip part 15 and the part to be connected 13 can be an integral structure or a split structure. When the anti-slip part 15 and the part to be connected 13 are an integral structure, the anti-slip part 15 and the part to be connected 13 can be integrally formed, the processing steps of the connection structure 10 are relatively simple, and the connection between the anti-slip part 15 and the part to be connected 13 is relatively stable. When the anti-slip part 15 and the part to be connected 13 are a split structure, the anti-slip part 15 and the part to be connected 13 are detachably or non-detachably connected. Wherein, the detachable installation method includes but is not limited to being threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to being welding, gluing connection or interference fit, etc.

[0065] When the connecting member 13 is inserted into the insertion hole 1113, the connecting member 13 can drive the anti-slip member 15 to extend into the insertion hole 1113. When the connecting member 13 is plugged into place, the anti-slip member 15 can extend into the installation cavity 115. In the case where the anti-slip member 15 is a hook, the hook can abut against the side wall of the connecting portion 1111. At this time, the cooperation between the anti-slip member 15 and the side wall of the connecting portion 1111 can effectively limit the movement of the connecting member 13 away from the functional box 11.

[0066] When the anti-slip component 15 is a hook connected to the component to be connected 13, the hook can be extended toward the plug hole 1113 together with the component to be connected 13. When the component to be connected 13 is installed in place, the hook is also installed in place (the hook is engaged with the side wall of the connecting part 1111). There is no need to install the anti-slip component 15 additionally. The installation of the anti-slip component 15 is relatively simple, and the installation steps of the connecting structure 10 are also relatively simple.

[0067] See also Figure 3 and Figure 4 In some embodiments, the connected component 13 includes an expansion bolt, which is inserted into the plug hole 1113 and cooperates with the side wall of the plug hole 1113. The anti-slip component 15 is provided at one end of the expansion bolt located in the installation cavity 115. The anti-slip component 15 is a hook, which is engaged with the side wall of the connecting part 1111.

[0068] When the part to be connected 13 is an expansion bolt, after the part to be connected 13 is inserted into the plug hole 1113, the hook can be extended into the installation cavity 115 to engage with the side wall of the connecting portion 1111. At this time, the part to be connected 13 can be tightly abutted against the side wall of the plug hole 1113 (connecting portion 1111). The friction between the part to be connected 13 and the side wall of the plug hole 1113 is relatively large, and the connection between the part to be connected 13 and the function box 11 is tighter. The part to be connected 13 is not easy to move away from the function box 11, and the part to be connected 13 is not easy to fall off relative to the function box 11.

[0069] In other embodiments, the anti-slip member 15 may include a screw passing through the connecting hole 1115 and the matching hole 131, and a hook connected to one end of the to-be-connected member 13. In this case, when the anti-slip member 15 connects the functional box 11 and the to-be-connected member 13, the connection between the functional box 11 and the to-be-connected member 13 is more stable, which can further prevent the to-be-connected member 13 from being detached from the functional box 11.

[0070] See also Figure 3 and Figure 5In some embodiments, at least two first protrusions 1117 are spaced apart on one of the box body 111 or the cover body 113. The first protrusions 1117 are arranged in a ring shape, and a first glue groove 1119 is formed between two adjacent first protrusions 1117. The other box body 111 or the cover body 113 is provided with a second protrusion 1131 that cooperates with the first glue groove 1119, and the second protrusion cooperates with the first glue groove 1119 in a concave-convex manner.

[0071] The number of first protrusions 1117 can be, but is not limited to, two, three, four, or more. When there are two first protrusions 1117, the number of first adhesive grooves 1119 is one. When there are three first protrusions 1117, the number of first adhesive grooves 1119 can be two. When there are four first protrusions 1117, the number of first adhesive grooves 1119 can be three. In the present application, there are two first protrusions 1117. First adhesive grooves 1119 can be used to load waterproof adhesive. Second protrusion 1131 can have the same annular structure as first protrusion 1117.

[0072] See also Figure 3 and Figure 5 In one embodiment, at least two first protrusions 1117 are spaced apart on a side of the box body 111 facing the cover 113, and a second protrusion 1131 is provided on a side of the cover 113 facing the box body 111. When the box body 111 and the cover 113 are connected, the second protrusions 1131 extend into the first adhesive groove 1119. The second protrusions 1131 and the first adhesive groove 1119 are bonded together with waterproof adhesive, thereby firmly connecting the box body 111 and the cover 113. Furthermore, the waterproof performance between the box body 111 and the cover 113 is improved, and external liquids are not easily able to enter the installation cavity 115 through the gap between the box body 111 and the cover 113.

[0073] See also Figure 3 and Figure 5 In another embodiment, a second protrusion 1131 is provided on the side of the box body 111 facing the cover body 113, and at least two first protrusions 1117 are provided on the side of the cover body 113 facing the box body 111. When the box body 111 and the cover body 113 are connected, the second protrusion 1131 extends into the first adhesive groove 1119. The second protrusion 1131 and the first adhesive groove 1119 are bonded together by waterproof adhesive, thereby firmly connecting the box body 111 and the cover body 113. The waterproof performance between the box body 111 and the cover body 113 is also improved, and external liquid is not easy to enter the installation cavity 115 through the gap between the box body 111 and the cover body 113.

[0074] In the embodiment of the present application, the box body 111 is provided with a first protrusion 1117, and the cover 113 is provided with a second protrusion 1131. When the box body 111 is provided with at least two first protrusions 1117 and the cover 113 is provided with a second protrusion 1131, the structure of the function box 11 is relatively simple, and the processing of the function box 11 is relatively simple.

[0075] See also Figure 3 and Figure 5 In other embodiments, at least two third protrusions are arranged at intervals on one of the box body 111 or the cover body 113, the third protrusions are arranged in a ring shape, and a second glue groove is formed between two adjacent third protrusions; at least two fourth protrusions are arranged at intervals on the other of the box body 111 or the cover body 113, the fourth protrusions are arranged in a ring shape, and a third glue groove 1133 is formed between two adjacent fourth protrusions; one of the third protrusions can be matched with the third glue groove 1133 in a concave-convex manner, and one of the fourth protrusions is matched with the second glue groove in a concave-convex manner.

[0076] The third protrusion may be identical to or different from the first protrusion 1117. The second adhesive groove may be identical to or different from the first adhesive groove 1119. The fourth protrusion may be identical to or different from the second protrusion 1131. This application uses the example of a case where the third protrusion is identical to the first protrusion 1117, the second adhesive groove is identical to the first adhesive groove 1119, and the fourth protrusion is identical to the second protrusion 1131. Both the second adhesive groove 1133 and the third adhesive groove 1133 can be used to store waterproof adhesive.

[0077] The number of third protrusions may be, but is not limited to, two, three, four, or more. When there are two third protrusions, the number of second adhesive grooves is one. When there are three third protrusions, the number of second adhesive grooves may be two. When there are four third protrusions, the number of second adhesive grooves may be three. The number of fourth protrusions may be, but is not limited to, two, three, four, or more. When there are two fourth protrusions, the number of third adhesive grooves 1133 is one. When there are three fourth protrusions, the number of third adhesive grooves 1133 may be two. When there are four fourth protrusions, the number of third adhesive grooves 1133 may be three. In this application, the number of third protrusions is two, and the number of second adhesive grooves is one. The number of fourth protrusions is two, and the number of third adhesive grooves 1133 is one.

[0078] See also Figure 3 and Figure 5In one embodiment, two spaced third protrusions are provided on the side of the box body 111 facing the cover body 113, and two spaced fourth protrusions are provided on the side of the cover body 113 facing the box body 111. In one example, a third protrusion near the center of the installation cavity 115 extends into the third glue groove 1133, and a fourth protrusion away from the center of the installation cavity 115 extends into the second glue groove. Waterproof glue is provided in both the second glue groove and the third glue groove 1133, so that the cover body 113 and the box body 111 can be firmly connected, and the waterproof effect of the functional box 11 is also better. In another example, a third protrusion away from the center of the installation cavity 115 extends into the third glue groove 1133, and a fourth protrusion near the center of the installation cavity 115 extends into the second glue groove. Waterproof glue is provided in both the second glue groove and the third glue groove 1133, so that the cover body 113 and the box body 111 can be firmly connected, and the waterproof effect of the functional box 11 is also better.

[0079] See also Figure 3 and Figure 5 In another embodiment, two fourth protrusions spaced apart are provided on the side of the box body 111 facing the cover body 113, and two third protrusions spaced apart are provided on the side of the cover body 113 facing the box body 111. In one example, a fourth protrusion close to the center of the mounting cavity 115 extends into the second glue groove, and a third protrusion away from the center of the mounting cavity 115 extends into the third glue groove 1133. Waterproof glue is provided in both the second glue groove 1133 and the third glue groove 1133, so that the cover body 113 and the box body 111 can be firmly connected, and the waterproof effect of the functional box 11 is also better. In another example, a fourth protrusion away from the center of the mounting cavity 115 extends into the second glue groove, and a third protrusion close to the center of the mounting cavity 115 extends into the third glue groove 1133. Waterproof glue is provided in both the second glue groove 1133 and the third glue groove 1133, so that the cover body 113 and the box body 111 can be firmly connected, and the waterproof effect of the functional box 11 is also better.

[0080] In the embodiment of the present application, two spaced third protrusions are provided on the side of the box body 111 facing the cover 113, and two spaced fourth protrusions are provided on the side of the cover 113 facing the box body 111. One of the third protrusions near the center of the mounting cavity 115 extends into the third adhesive groove 1133, while the fourth protrusion farther from the center of the mounting cavity 115 extends into the second adhesive groove. This provides a more stable connection between the box body 111 and the cover 113, and enhances the waterproofing of the functional box 11, further preventing external liquids from entering the mounting cavity 115 through the gap between the box body 111 and the cover 113.

[0081] See also Figure 3 and Figure 5In some embodiments, in the thickness direction Y of the functional box 11, the height of the third protrusion near the mounting cavity 115 is lower than the height of the third protrusion farther from the mounting cavity 115. In this case, when the box body 111 is connected to the cover body 113, the fourth protrusion extending into the second adhesive groove will squeeze the waterproof adhesive in the second adhesive groove, causing the waterproof adhesive to easily overflow from the second adhesive groove. When the height of the third protrusion near the mounting cavity 115 is lower than the height of the third protrusion farther from the mounting cavity 115, the waterproof adhesive can flow into the mounting cavity 115 through the third protrusion near the mounting cavity 115, thereby effectively preventing the waterproof adhesive from overflowing to the outside of the functional box 11 and affecting the overall appearance of the functional box 11. It is understandable that the waterproof adhesive has a high viscosity. When the waterproof adhesive flows into the mounting cavity 115 through the third protrusion, the waterproof adhesive can solidify on the sidewalls of the mounting cavity 115, thereby preventing the waterproof adhesive from flowing onto other components within the mounting cavity 115 and affecting the operation of other components within the mounting cavity 115. In addition, when the height of the third protrusion close to the installation cavity 115 is lower than the height of the third protrusion far from the installation cavity 115 , less material can be used for the third protrusion, thereby saving material cost.

[0082] See also Figure 3 and Figure 5 In other embodiments, in the thickness direction Y of the functional box 11, the height of the fourth protrusion near the mounting cavity 115 is lower than the height of the fourth protrusion farther from the mounting cavity 115. In this case, when the box body 111 is connected to the cover body 113, the fourth protrusion extending into the third adhesive groove 1133 will squeeze the waterproof adhesive within the third adhesive groove 1133, causing the waterproof adhesive to easily overflow from the third adhesive groove 1133. When the height of the fourth protrusion near the mounting cavity 115 is lower than the height of the fourth protrusion farther from the mounting cavity 115, the waterproof adhesive can flow into the mounting cavity 115 through the fourth protrusion near the mounting cavity 115, effectively preventing the waterproof adhesive from overflowing outside the functional box 11 and affecting the overall appearance of the functional box 11. It will be appreciated that the waterproof adhesive has a high viscosity, and as the waterproof adhesive flows through the fourth protrusion into the mounting cavity 115, it can solidify on the sidewalls of the mounting cavity 115, thereby preventing the waterproof adhesive from flowing onto other components within the mounting cavity 115 and affecting their operation. In addition, when the height of the fourth protrusion close to the installation cavity 115 is lower than the height of the fourth protrusion far from the installation cavity 115 , less material can be used for the fourth protrusion, thereby saving material cost.

[0083] See also Figure 3 and Figure 5In some other embodiments, in the thickness direction Y of the functional box 11, the height of the third protrusion near the mounting cavity 115 is lower than the height of the third protrusion farther from the mounting cavity 115; and the height of the fourth protrusion near the mounting cavity 115 is lower than the height of the fourth protrusion farther from the mounting cavity 115. This further prevents the waterproofing glue from overflowing onto the exterior of the functional box 11, and the waterproofing agent does not affect the overall appearance of the functional box 11, thereby improving the aesthetics of the functional box 11. Furthermore, less material is required for both the third and fourth protrusions, saving material costs.

[0084] See also Figure 3 In some embodiments, the component to be connected 13 includes a sleeve 133 and a mounting portion 135. The sleeve 133 includes a sleeve body 1331 and a protrusion 1333 provided at one end of the sleeve body 1331. An annular sealing member 1335 is formed on the outer side of the protrusion 1333. The protrusion 1333 extends into the plug hole 1113, and the sealing member 1335 abuts against the inner wall of the plug hole 1113. The mounting portion 135 passes through the plug hole 1113. One end of the mounting portion 135 located in the installation cavity 115 is connected to the functional box 11 via the anti-slip member 15. The end of the mounting portion 135 located outside the installation cavity 115 extends into the protrusion 1333 to connect with the sleeve body 1331. The protrusion 1333 is sleeved on the outer wall of the mounting portion 135.

[0085] Preferably, the sleeve 133 can be made of soft rubber, and the mounting portion 135 can be made of hard rubber. When the mounting portion 135 is made of hard rubber, when the mounting portion 135 is connected to the function box 11, the connection between the component 13 to be connected and the function box 11 is relatively stable. When the sleeve 133 is made of soft rubber, the soft rubber can be easily deformed, thereby facilitating the user to adjust the position and shape of the component 13 to be connected so that the component 13 to be connected fits the user's head better. In this case, the connection between the sleeve 133 and the mounting portion 135 can be a two-color injection molding integral molding, thereby, the connection between the sleeve 133 and the mounting portion 135 is relatively tight, and the sleeve 133 and the mounting portion 135 are not easy to separate.

[0086] The sealing member 1335 protrudes from the side wall of the protruding portion 1333. When the mounting portion 135 is provided with the plug hole 1113, the mounting portion 135 can drive the protruding portion 1333 to extend into the plug hole 1113. When the component to be connected 13 and the functional box 11 are connected in place, the sealing member 1335 can abut against the inner wall of the plug hole 1113 (the inner side wall of the connecting portion 1111). Since the sealing member 1335 is made of soft rubber, when the sealing member 1335 abuts against the inner wall of the plug hole 1113, the sealing member 1335 will be squeezed and deformed to a certain extent. As a result, there is almost no gap between the sealing member 1335 and the inner wall of the plug hole 1113, and it is difficult for external liquid to enter the mounting cavity 115 through the gap between the component to be connected 13 and the plug hole 1113. The waterproof effect of the connection structure 10 is better.

[0087] See also Figure 3 In some embodiments, the sealing member 1335 includes a plurality of sealing members 1335, which are sequentially spaced apart along the extension direction of the protrusion 1333. For example, the number of sealing members 1335 can be two, three, four, or more. When there are multiple sealing members 1335, each of the sealing members 1335 abuts against the inner wall of the insertion hole 1113, creating a tighter connection between the connection member 13 and the inner wall of the insertion hole 1113. This further enhances the waterproofing of the connection structure 10, preventing external liquids from entering the mounting cavity 115.

[0088] See also Figure 3 In some embodiments, the seal 1335 has a closed annular structure. In this case, the seal 1335 has a simpler structure and is easier to manufacture. Furthermore, the seal 1335 can abut against the entire circumference of the inner wall of the insertion hole 1113, improving the waterproofing of the connection structure 10. In other embodiments, the seal 1335 has an intermittent annular structure. In this case, the seal 1335 requires less material, saving material.

[0089] See also Figure 6 The earphone system 1000 of the embodiment of the present application includes the earphone 100 of the embodiment described above and a charging box 300, which is used to charge the earphone 100. The charging box 300 is provided with a charging compartment. When the earphone 100 needs to be charged, the battery box 117 of the earphone 100 can be accommodated in the charging compartment, and the charging box 300 can charge the battery inside the battery box 117.

[0090] In the earphone system 1000 of the embodiment of the present application, the part to be connected 13 extends into the plug hole 1113 to be connected with the function box 11. The anti-slip part 15 is located in the installation cavity 115. The anti-slip part 15 is used to further firmly connect the function box 11 and the part to be connected 13, which can effectively prevent the part to be connected 13 from falling off relative to the function box 11. Compared with the current connection structure 10, in the connection structure 10 of the present application, the anti-slip part 15 can firmly connect the function box 11 and the part to be connected 13 without passing through the function box 11, and external liquid will not enter the installation cavity 115 from the gap between the anti-slip part 15 and the function box 11. The waterproof effect of the connection structure 10 is good, which can effectively prevent external liquid from entering the installation cavity 115 and affecting the normal operation of the mainboard compartment in the function box 11.
