[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-dropping piece that fixes the two parts (the function box assembly and the ear hook, or the function box assembly and the back hook) is usually arranged on the outside of the function box. The anti-dropping piece 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-dropping piece 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), earphone 100 ( Figure 1 ) and earphone system 1000 ( Figure 6 shown).

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

[0046] Among them, the bone conduction earphone 100 uses the human skeleton as a medium, and the bone conduction earphone 100 converts sound into mechanical vibration, which transmits sound waves through the human skeleton so that the user can hear the sound. The sound of the bone conduction earphone 100 acts on the skeleton, and long-term use will not cause a great impact on the eardrum of the user's ear, which can effectively protect the user's hearing. The air conduction earphone 100 transmits sound through air vibration, and the air conduction earphone 100 has good sound quality and penetration. The earphone 100 of the present application is described by taking the bone conduction earphone 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 part to be connected 13 is provided with a protrusion 132, and the protrusion 132 abuts against the side wall of the function box 11. 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 a control function. 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 work 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 installation cavity 115 is used for installing components such as the battery and circuit board of the headset 100. The box body 111 and the cover body 113 are detachably connected. When the cover body 113 is removed from the box body 111, the battery and circuit board of the headset 100 can be easily installed in the installation cavity 115, and the battery and circuit board of the headset 100 can also be easily repaired and replaced. When the cover body 113 is installed in the box body 111, the box body 111 and the cover body 113 can jointly protect the components inside the installation cavity 115, and can effectively prevent the risk of external dust and water vapor entering the installation cavity 115 and damaging the components in the installation 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 can be bonded and connected using waterproof glue. At this time, the connection between the box body 111 and the cover 113 is relatively stable, the cover 113 is not easy 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 easy to enter the installation cavity 115 from 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 works underwater, external water is not easy to enter the installation cavity 115 from the gap between the box body 111 and the cover 113, which can effectively avoid the problem of external liquid affecting the normal operation of the components in the installation cavity 115. Among them, the waterproof glue can be but is not limited to polyurethane waterproof glue, nano-silicon waterproof glue, acrylate waterproof glue, or ethylene-vinyl acetate copolymer waterproof glue, etc.

[0051] See also Figure 3 and Figure 4 , the member to be connected 13 is used to extend into the plug hole 1113 to connect with the function box 11. The protrusion 132 is provided on the peripheral wall of the member to be connected 13, and when at least part of the member to be connected 13 extends into the plug hole 1113 and is installed in place with the function box 11, the protrusion 132 abuts against the side wall of the function box 11. The protrusion 132 is used to position the installation of the member to be connected 13, which can effectively avoid the problem of the member to be connected 13 not being installed in place or being installed too much, and when the protrusion 132 is in close contact with the side wall of the function box 11, it can also prevent external liquid from entering the plug hole 1113 through the gap between the protrusion 132 and the side wall of the function box 11.

[0052] 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 on the back of the ear, so that the wearing stability of the earphone 100 can be improved, and the earphone 100 is not easy to fall 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 with the skin of the human body. When the earphone 100 is in use, the transducer component 30 can vibrate mechanically to enable the user to hear the sound.

[0053] In the case where the part 13 to be connected is the ear hook 137 of the earphone 100 or the back hook 139 of the earphone 100, a connecting portion 1111 is provided at one end of the box body 111 in the length direction X of the function box 11, and the connecting portion 1111 is used to connect with the part 13 to be connected, so that the function box 11 and the part 13 to be connected can be firmly connected. In the case where the part 13 to be connected includes the ear hook 137 of the earphone 100 and the back hook 139 of the earphone 100, in the length direction X of the function box 11, the ear hook 137 and the back hook 139 are respectively connected to the opposite ends of the function box 11, and in this case, the box body 111 is provided with connecting portions 1111 at both opposite ends of the function box 11 in the length direction X.

[0054] 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 part 1111. The anti-slip part 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 from the outside of the function box 11 into the installation cavity 115 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 on the surface of the function box 11 to install the anti-slip part 15, and 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 function 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. The function box 11 also has better aesthetics.

[0055] 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 connect with the function box 11. The anti-dropping member 15 is located in the installation cavity 115, and the anti-dropping member 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-dropping member 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-dropping member 15 and the function box 11. The waterproof effect of the connection structure 10 is better, which can effectively prevent the problem of external liquid entering the installation cavity 115 and affecting the normal operation of the mainboard compartment in the function box 11.

[0056] The connection structure 10 is further described below with reference to the accompanying drawings.

[0057] See also Figure 3 and Figure 4 In some embodiments, the connecting portion 1111 is further provided with a connecting hole 1115, the connecting hole 1115 is located in the installation cavity 115 and is connected to the plug hole 1113, the part to be connected 13 is provided with a matching hole 131, the matching hole 131 corresponds to the connecting hole 1115, and 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.

[0058] The connecting hole 1115 is provided on the side wall of the connecting portion 1111. The anti-slip member 15 of the present 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 function 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 a direction away from the function 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.

[0059] The anti-detachment part is provided with a connecting hole 1115 and a matching hole 131, so that when the function box 11 is connected to the part 13 to be connected, the connection method between the function box 11 and the part 13 to be connected is relatively simple, and only holes need to be opened on the function box 11 and the part 13 to be connected. The structure of the function box 11 and the part 13 to be connected is relatively simple, the processing is relatively simple, and the connection between the function box 11 and the part 13 to be connected is also relatively stable.

[0060] 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°.

[0061] The extending direction of the matching hole 131 is the same as the extending direction of the connecting hole 1115, so that the anti-dropping member 15 can be conveniently provided with the connecting hole 1115 and the matching hole 131. The extending direction of the plug hole 1113 is the direction in which the member 13 to be connected 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-dropping member 15 is inserted into the connecting portion 1111 and the member 13 to be connected. In the case that the direction in which the member 13 to be connected extends into the connecting portion 1111 is different from the direction in which the anti-dropping member 15 is inserted into the connecting portion 1111, the anti-dropping member 15 can lock the function box 11 and the member 13 to be connected, and can effectively prevent the member 13 to be connected from moving in a direction 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.

[0062] See also Figure 3 and Figure 4 Preferably, 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°. At this time, the anti-dropping member 15 can make the connection between the function box 11 and the to-be-connected member 13 more stable, and can further effectively prevent the to-be-connected member 13 from moving in a direction away from the connecting portion 1111, and the processing of the connecting hole 1115 and the plug hole 1113 is also relatively simple.

[0063] In the case where the extension direction of the connection hole 1115 is perpendicular to the extension direction of the plug hole 1113, in some embodiments, the plug hole 1113 penetrates two opposite side walls of the connection portion 1111, and the connection hole 1115 penetrates the top wall of the connection portion 1111, and the two ends of the top wall connect the two side walls. The connection portion 1111 includes two opposite side walls in the length direction X of the function box 11, and the connection 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 penetrates the connection 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.

[0064] See also Figure 3 and Figure 4 In other embodiments, at least part of the to-be-connected member 13 extends into the installation cavity 115, the anti-dropout member 15 is disposed at one end of the to-be-connected member 13 located in the installation cavity 115, and the anti-dropout member 15 cooperates with the side wall of the connecting portion 1111 to connect the functional box 11 with the to-be-connected member 13. Specifically, in some embodiments, the anti-dropout member 15 is a hook that can be snapped, and the hook is snapped with the side wall of the connecting portion 1111.

[0065] Among them, the anti-slip member 15 is connected to one end of the part to be connected 13. At this time, the anti-slip member 15 and the part to be connected 13 can be an integral structure or a split structure. When the anti-slip member 15 and the part to be connected 13 are an integral structure, the anti-slip member 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 member 15 and the part to be connected 13 is relatively stable. When the anti-slip member 15 and the part to be connected 13 are a split structure, the anti-slip member 15 and the part to be connected 13 are detachably or non-detachably connected. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0066] When the member to be connected 13 is inserted into the plug hole 1113, the member to be connected 13 can drive the anti-dropping member 15 to be inserted into the plug hole 1113. When the member to be connected 13 is plugged in place, the anti-dropping member 15 can be inserted into the installation cavity 115. When the anti-dropping member 15 is a hook, the hook can be abutted against the side wall of the connecting portion 1111. At this time, the cooperation between the anti-dropping member 15 and the side wall of the connecting portion 1111 can effectively limit the movement of the member to be connected 13 in the direction away from the function box 11.

[0067] In the case where the anti-slip component 15 is a hook connected to the component 13 to be connected, the hook can be extended toward the plug-in hole 1113 together with the component 13 to be connected. When the component 13 to be connected is installed in place, the hook is also installed in place (the hook is engaged with the side wall of the connecting portion 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.

[0068] 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 arranged 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.

[0069] When the connected part 13 is an expansion bolt, after the connected part 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 connected part 13 can be tightly abutted against the side wall of the plug hole 1113 (connecting portion 1111), and the friction between the connected part 13 and the side wall of the plug hole 1113 is relatively large. The connection between the connected part 13 and the function box 11 is tighter, and the connected part 13 is not easy to move away from the function box 11, and the connected part 13 is not easy to fall off relative to the function box 11.

[0070] In other embodiments, the anti-dropping member 15 may include a screw penetrating the connection hole 1115 and the matching hole 131, and a hook connected to one end of the member to be connected 13. In this case, when the anti-dropping member 15 connects the function box 11 and the member to be connected 13, the connection between the function box 11 and the member to be connected 13 is more stable, and the problem of the member to be connected 13 being separated from the function box 11 can be further avoided.

[0071] See also Figure 3 and Figure 5 In some embodiments, at least two first protrusions 1117 are spaced apart on one of the box body 111 or the cover body 113.

When the box body 111 and the cover body 113 are connected, the second protrusion 1131 extends into the first adhesive groove 1119, and the second protrusion 1131 and the first adhesive groove 1119 are bonded by waterproof adhesive, so that the box body 111 and the cover body 113 are fixedly connected, and the waterproof performance between the box body 111 and the cover body 113 is also good, 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] See also Figure 3 and Figure 5In another embodiment, a second protrusion 1131 is provided on one side of the box body 111 facing the cover body 113, and at least two first protrusions 1117 are provided on one side of the cover body 113 facing the box body 111.

[0075] The box body 111 of the embodiment of the present application is provided with a first protrusion 1117, and the cover body 113 is provided with a second protrusion 1131. When at least two first protrusions 1117 are provided on the box body 111 and the second protrusion 1131 is provided on the cover body 113, the structure of the function box 11 is relatively simple, and the processing of the function box 11 is relatively simple.

The fourth protrusion may be the same as the second protrusion 1131, or the fourth protrusion may be different from the second protrusion 1131. This application is described by taking the third protrusion being the same as the first protrusion 1117, the second glue groove being the same as the first glue groove 1119, and the fourth protrusion being the same as the second protrusion 1131 as an example. Both the second glue groove and the third glue groove 1133 can be used to load waterproof glue therein.

The number of the third protrusions of the present application is two, and the number of the second glue grooves is one. The number of the fourth protrusions is two, and the number of the third glue grooves 1133 is one.

[0079] See also Figure 3 and Figure 5 In one embodiment, two spaced third protrusions are provided on one side of the box body 111 facing the cover body 113, and two spaced fourth protrusions are provided on one side of the cover body 113 facing the box body 111. In one example, a third protrusion close to 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, and 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 good. 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 close to the center of the installation cavity 115 extends into the second glue groove, and 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 good.

[0080] See also Figure 3 and Figure 5 In another embodiment, two fourth protrusions spaced apart are provided on one side of the box body 111 facing the cover body 113, and two third protrusions spaced apart are provided on one 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, and 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 good. 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, and 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 good.

[0081] The box body 111 of the embodiment of the present application is provided with two spaced third protrusions on one side facing the cover body 113, and the cover body 113 is provided with two spaced fourth protrusions on one side facing the box body 111, and a third protrusion close to 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. At this time, the connection between the box body 111 and the cover body 113 is more stable, and the waterproof effect of the functional box 11 is also better, which can further prevent external liquid from entering the installation cavity 115 through the gap between the box body 111 and the cover body 113.

[0082] See also Figure 3 and Figure 5 In some embodiments, in the thickness direction Y of the function box 11, the height of the third protrusion close to the installation cavity 115 is lower than the height of the third protrusion away from the installation cavity 115. At this time, when the box body 111 is connected to the cover body 113, the fourth protrusion extending into the second glue groove will squeeze the waterproof glue in the second glue groove, and the waterproof glue is easy to overflow from the second glue groove. In the case where the height of the third protrusion close to the installation cavity 115 is lower than the height of the third protrusion away from the installation cavity 115, the waterproof glue can flow into the installation cavity 115 through the third protrusion close to the installation cavity 115, thereby effectively preventing the waterproof glue from overflowing to the outside of the function box 11 and affecting the overall appearance of the function box 11. It can be understood that the waterproof glue has a large viscosity. When the waterproof glue flows into the installation cavity 115 through the third protrusion, the waterproof glue can solidify on the side wall of the installation cavity 115, thereby preventing the waterproof glue from flowing to other components in the installation cavity 115 to affect the operation of other components in the installation 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.

[0083] See also Figure 3 and Figure 5In other embodiments, in the thickness direction Y of the function box 11, the height of the fourth protrusion close to the installation cavity 115 is lower than the height of the fourth protrusion away from the installation cavity 115. At this time, when the box body 111 is connected to the cover body 113, the fourth protrusion extending into the third glue groove 1133 will squeeze the waterproof glue in the third glue groove 1133, and the waterproof glue is easy to overflow from the third glue groove 1133. In the case where the height of the fourth protrusion close to the installation cavity 115 is lower than the height of the fourth protrusion away from the installation cavity 115, the waterproof glue can flow into the installation cavity 115 through the fourth protrusion close to the installation cavity 115, thereby effectively preventing the waterproof glue from overflowing to the outside of the function box 11 and affecting the overall appearance of the function box 11. It can be understood that the waterproof glue has a large viscosity. When the waterproof glue flows into the installation cavity 115 through the fourth protrusion, the waterproof glue can solidify on the side wall of the installation cavity 115, thereby preventing the waterproof glue from flowing to other components in the installation cavity 115 to affect the operation of other components in the installation cavity 115. 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.

[0084] See also Figure 3 and Figure 5 In some other embodiments, in the thickness direction Y of the function box 11, the height of the third protrusion close to the installation cavity 115 is lower than the height of the third protrusion away from the installation cavity 115; the height of the fourth protrusion close to the installation cavity 115 is lower than the height of the fourth protrusion away from the installation cavity 115. In this case, the waterproof glue can be further prevented from overflowing to the outside of the function box 11, and the waterproof agent will not affect the overall appearance of the function box 11, and the appearance of the function box 11 is better. In addition, the materials used for the third protrusion and the fourth protrusion can be less, which can save a certain amount of material cost.

[0085] See also Figure 3 and Figure 4 In some embodiments, the to-be-connected member 13 includes a sleeve 133 and a mounting portion 135. The sleeve 133 includes a sleeve body 1331 and a protrusion 1333 disposed 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-in hole 1113, and the sealing member 1335 abuts against the inner wall of the plug-in hole 1113. The mounting portion 135 passes through the plug-in hole 1113. One end of the mounting portion 135 located in the mounting cavity 115 is connected to the function box 11 through the anti-slip member 15. One end of the mounting portion 135 located outside the mounting cavity 115 extends into the protrusion 1333 to be connected to the sleeve body 1331. The protrusion 1333 is sleeved on the outer wall of the mounting portion 135.

[0086] The protrusion 132 is formed by the sleeve body 1331 and the mounting portion 135. Preferably, the sleeve 133 can be soft glue, and the mounting portion 135 can be hard glue. In the case where the mounting portion 135 is hard glue, when the mounting portion 135 is connected to the function box 11, the connection between the to-be-connected part 13 and the function box 11 is relatively stable. When the sleeve 133 is soft glue, the soft glue can be easily deformed, so that the user can adjust the position and shape of the to-be-connected part 13 to make the to-be-connected part 13 fit the user's head better. At this time, the connection between the sleeve 133 and the mounting portion 135 can be two-color injection 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.

[0087] 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 member to be connected 13 is connected to the function box 11, 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 a 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. Therefore, 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 member to be connected 13 and the plug hole 1113, and the waterproof effect of the connection structure 10 is better.

[0088] See also Figure 3 In some embodiments, the sealing member 1335 includes a plurality of sealing members 1335, and the plurality of sealing members 1335 are sequentially arranged at intervals along the extension direction of the protrusion 1333. Exemplarily, the number of sealing members 1335 may be two, three, four or more. In the case where the number of sealing members 1335 is multiple, the plurality of sealing members 1335 abut against the inner wall of the plug hole 1113, and the connection between the connecting member 13 and the inner wall of the plug hole 1113 is tighter, thereby further enhancing the waterproof effect of the connection structure 10, and external liquid is not easy to enter the installation cavity 115.

[0089] See also Figure 3 In some embodiments, the seal 1335 is a closed annular structure. In this case, the seal 1335 has a relatively simple structure and is relatively easy to process. The seal 1335 can abut against the circumference of the inner wall of the plug hole 1113, and the waterproof effect of the connection structure 10 is better. In other embodiments, the seal 1335 is an intermittent annular structure. In this case, the seal 1335 uses less material, which can save material.

[0090] See also Figure 6The earphone system 1000 of the embodiment of the present application includes the earphone 100 of the above embodiment and a charging box 300, and the charging box 300 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.

[0091] 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-dropping member 15 is located in the installation cavity 115, and the anti-dropping member 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-dropping member 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-dropping member 15 and the function box 11. The waterproof effect of the connection structure 10 is better, which can effectively prevent the problem of external liquid entering the installation cavity 115 and affecting the normal operation of the mainboard compartment in the function box 11.

[0092] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. At the same time, other implementation methods can be derived from the above-mentioned embodiments, so that structural and logical replacements and changes can be made without departing from the scope of this disclosure.

[0093] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
