Description

Technical Field

[0001] The present application relates to the field of earphone technology, and more specifically, to a connection structure, an earphone, and an earphone system. Background Art

[0002] Typically, the transducer assembly (which can also be a battery box assembly or a control box assembly) is connected to the ear hook, and the seal between the two is usually achieved by adding a sealing ring. Specifically, the sealing ring is first assembled on the transducer assembly or the ear hook, and then the sealing glue is injected to complete the seal. Since the sealing ring is added and the sealing glue is combined, the labor and material costs increase, and the waterproof effect of this method is not good. External liquid entering the transducer assembly will affect the sound quality of the transducer assembly. Utility Model Content

DETAILED DESCRIPTION

[0032] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0035] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0036] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Typically, the transducer assembly (which may also be a battery box assembly or a control box assembly) is connected to the ear hook, and the seal between the two is usually achieved by adding a sealing ring. Specifically, the sealing ring is first assembled on the transducer assembly or the ear hook, and then the sealing glue is injected to complete the seal. Since the sealing ring is added and the sealing glue is combined, the labor and material costs increase, and the waterproof effect of this method is not good. External liquid entering the transducer assembly will affect the sound quality of the transducer assembly. In order to solve this problem, the embodiment of the present application provides a connection structure 100 ( Figure 2 As shown), earphones 1000 ( Figure 1 shown) and earphone system 10000 ( Figure 5 shown).

[0039] See also Figure 1 The earphone 1000 of the embodiment of the present application includes a connection structure 100. In some embodiments, the earphone 1000 includes a bone conduction earphone 1000 and an air conduction earphone 1000.

[0040] Bone conduction earphones 1000 use human bones as a medium, converting sound into mechanical vibrations. These mechanical vibrations transmit sound waves through the human bones, allowing the user to hear the sound. Since the sound of bone conduction earphones 1000 acts on the bones, long-term use will not significantly affect the user's eardrum, effectively protecting the user's hearing. Air conduction earphones 1000 transmit sound through air vibrations, offering superior sound quality and penetration. The earphones 1000 of this application will be described using bone conduction earphones 1000 as an example.

[0041] See also Figures 2 to 4 The connection structure 100 of the embodiment of the present application includes an installation box 10 and a connection component 30. The installation box 10 is provided with a connection hole 11 communicating with the outside. The connection component 30 is connected to the installation box 10, and the connection hole 11 is used for the connection component 30 to extend into. The connection component 30 includes a connection body 31 and a connection member 33. At least a portion of the connection member 33 is sleeved on the connection body 31. The connection body 31 and the connection member 33 are integrally formed by two-color injection molding. At least a portion of the connection member 33 sleeved on the connection body 31 protrudes in a direction away from the connection body 31 to form an annular sealing portion 331. The sealing portion 331 abuts against the side wall of the connection hole 11.

[0042] Specifically, see Figure 1 and Figure 2 The installation box 10 is used to house the battery, circuit board, and other components of the headset 1000. In some embodiments, the installation box 10 includes a battery compartment 101 for storing batteries, a control box 103 with control functions, and / or a transducer box 105 with a vibration function. In some embodiments, the installation box 10 may include the control box 103. The control box 103 can be used to control the headset 1000's power on and off and adjust the headset's volume. In other embodiments, the installation box 10 may include the battery compartment 101. The battery compartment 101 is used to hold batteries, which power the headset 1000 to ensure proper operation. In still other embodiments, the installation box 10 may include the transducer box 105, which may house a vibration component. When the headset 1000 is in use, the transducer box 105 can be placed against the human skin. When powered, the vibration component drives the transducer box 105 to vibrate. The vibration of the transducer box 105 transmits sound waves through the human skeleton, allowing the user to hear the sound. In some further embodiments, the installation box 10 may include a control box 103 , a battery box 101 , and a transducer box 105 .

[0043] See also Figure 3 and Figure 4The connecting assembly 30 is configured to extend into the connecting hole 11 to connect to the installation box 10. A wire may be provided within the connecting assembly 30. When the connecting assembly 30 is connected to the installation box 10, the wire within the connecting assembly 30 can electrically connect to components within the installation box 10. In certain embodiments, the connecting assembly 30 includes an ear hook 301 for the earphone 1000 and / or a back hook 303 for the earphone 1000. When a user wears the earphone 1000, the back hook 303 is worn on the head, while the ear hook 301 is worn behind the ear. This improves the wearing stability of the earphone 1000 and prevents it from falling off when the user is outdoors or exercising. The back hook 303 is used to connect the battery compartment 101 and the control box 103. The ear hook 301 is used to connect the battery compartment 101 and the transducer box 105, and to connect the control box 103 and the transducer box 105.

[0044] When the installation box 10 is a transducer box 105, the connecting component 30 may be an ear hook 301, in which case a connecting hole 11 is provided at one end of the installation box 10. When the installation box 10 is a control box 103 or a battery box 101, the connecting component 30 may include an ear hook 301 and a back hook 303. In this case, the installation box 10 is provided with connecting holes 11 at opposite ends in the longitudinal direction of the installation box 10. One connecting hole 11 of the installation box 10 is used for inserting the ear hook 301, and the other connecting hole 11 of the installation box 10 is used for inserting the back hook 303. This application is described by taking the installation box 10 as a transducer box 105 and the connecting component 30 including the ear hook 301 as an example.

[0045] The connector 33 is primarily used to position the wires of the earphone 1000, while the connector body 31 is primarily used to securely connect the connector assembly 30 to the mounting box 10. At least a portion of the connector 33 is sleeved onto the connector body 31. When at least a portion of the connector assembly 30 extends into the connecting hole 11, at least a portion of the connector body 31 and at least a portion of the connector 33 can both extend into the connecting hole 11. The connector 33 also serves to seal the gap between the connector assembly 30 and the sidewall of the connecting hole 11.

[0046] The connecting body 31 and the connecting member 33 of this application are made of different materials. By using a two-shot injection molding process to form an integral part of the connecting body 31 and the connecting member 33, the connecting assembly 30 requires fewer processing steps and is more convenient to manufacture. Furthermore, the connection between the connecting body 31 and the connecting member 33 is tighter, making them less likely to become loose.

[0047] See also Figure 3 and Figure 4Preferably, in some embodiments, the hardness of the connecting body 31 is greater than the hardness of the connecting member 33. In this case, after the connecting assembly 30 is inserted into the connecting hole 11, the connection strength between the connecting assembly 30 and the installation box 10 is high, and the connecting assembly 30 is not likely to fall off relative to the installation box 10. If the hardness of the connecting body 31 is less than the hardness of the connecting member 33, the connection strength between the connecting assembly 30 and the installation box 10 is low, and the connecting assembly 30 is likely to fall off relative to the installation box 10, resulting in a poor user experience.

[0048] In some embodiments, the connecting body 31 is made of hard rubber, and the connecting member 33 is made of soft rubber. When the connecting body 31 is made of hard rubber, the connection between the connecting assembly 30 and the installation box 10 is more stable when the connecting body 31 is connected to the installation box 10, and the connection strength between the connecting assembly 30 and the installation box 10 is higher. When the connecting member 33 is made of soft rubber, the soft rubber can easily deform, allowing the user to adjust the position and shape of the connecting member 33 to better fit the connecting assembly 30 to the user's head. The soft rubber can be, but is not limited to, rubber, silicone, thermoplastic elastomer, or polyvinyl chloride.

[0049] The connecting member 33 is sleeved on the partial structure of the connecting body 31 and is provided with a sealing portion 331. The sealing portion 331 is used to seal the gap between the connecting component 30 and the connecting hole 11 to prevent external liquid from entering the installation box 10 through the gap between the connecting component 30 and the connecting hole 11. When the connecting component 30 and the connecting hole 11 are connected in place, the annular sealing portion 331 can abut against the entire circle of the side wall of the connecting hole 11. Since the sealing portion 331 is made of soft rubber, when the sealing portion 331 abuts against the inner wall of the connecting hole 11, the sealing portion 331 will be squeezed and deformed to a certain extent. As a result, there is almost no gap between the sealing portion 331 and the side wall of the connecting hole 11, and it is difficult for external liquid to enter the installation box 10 through the gap between the connecting component 30 and the connecting hole 11. The waterproof effect of the connection structure 100 is better. Furthermore, when the sealing portion 331 abuts the side wall of the connection hole 11, the friction between the sealing portion 331 and the side wall of the connection hole 11 is relatively large, thereby improving the connection stability between the connection assembly 30 and the installation box 10, and the connection assembly 30 is not easily loosened relative to the installation box 10. The provision of the sealing portion 331 on the connector 33 of the present application can effectively improve the waterproof level of the connection structure 100 and also improve the connection strength between the connection assembly 30 and the installation box 10. The structure of the connection assembly 30 is also relatively simple, and the processing is relatively simple, and the installation of the connection structure 100 is also relatively simple.

[0050] In the connection structure 100 of the embodiment of the present application, the connection body 31 and the connection member 33 are integrally formed by double-color injection molding, and the connection member 33 is sleeved on at least a portion of the connection body 31 and protrudes in a direction away from the connection body 31 to form an annular sealing portion 331. Compared with the current connection structure 100, the connection structure 100 of the present application does not require an additional sealing ring, and the connection between the connection component 30 and the installation box 10 is relatively simple, which can effectively save manpower and material costs. In addition, when the connection component 30 is connected to the installation box 10, the sealing portion 331 abuts the side wall of the connection hole 11, and the connection strength between the connection component 30 and the installation box 10 is high. The waterproof effect of the connection structure 100 is also good, and it is difficult for external liquid to flow into the interior of the installation box 10 through the gap between the connection component 30 and the side wall of the connection hole 11.

[0051] The connection structure 100 will be further described below with reference to the accompanying drawings.

[0052] See also Figure 3 and Figure 4 In some embodiments, the connector 33 includes a main body portion 333 and a protrusion 335 connected to each other, and the outer side of the protrusion 335 protrudes to form a sealing portion 331; the connecting body 31 includes a first connecting portion 311 and a second connecting portion 313 connected to each other, the main body portion 333 is sleeved on the first connecting portion 311, and the protrusion 335 is sleeved on the second connecting portion 313. A protrusion 315 extending toward the connector 33 is provided on one side of the first connecting portion 311 close to the second connecting portion 313, and a recess 3331 is formed on the inner side of the main body portion 333, and the protrusion 315 cooperates with the recess 3331.

[0053] When the connecting assembly 30 is connected to the installation box 10, the second connecting portion 313 and the protrusion 335 extend into the connecting hole 11, and the sealing portion 331 on the protrusion 335 abuts the sidewall of the connecting hole 11, thereby enhancing the connection strength between the connecting assembly 30 and the installation box 10 and improving the waterproof effect of the connecting structure 100. During the two-color injection molding process between the connecting body 31 and the connecting member 33, after the molten connecting member 33 solidifies on the surface of the connecting body 31, the body 333 forms a recess 3331 at a position corresponding to the protrusion 315. When the protrusion 315 is provided on a side of the first connecting portion 311 near the second connecting portion 313 and the recess 3331 is formed on the inner side of the body 333, the protrusion 315 cooperates with the recess 3331 to increase the connection area between the first connecting portion 311 and the body 333, thereby improving the connection strength between the connecting body 31 and the connecting member 33 and preventing the connecting member 33 from loosening relative to the connecting body 31.

[0054] The number of protrusions 315 may be, but is not limited to, one, two, three, four or more. When the number of protrusions 315 is one, the protrusion 315 may be provided at any position on the side of the first connecting portion 311 close to the second connecting portion 313. The number of recesses 3331 may also be one, and the position of the recess 3331 corresponds to the position of the protrusion 315. In this case, the structure of the connecting body 31 is relatively simple and the processing is relatively simple. When the number of protrusions 315 is multiple, the multiple protrusions 315 may be uniformly or non-uniformly provided on the side of the first connecting portion 311 close to the second connecting portion 313. The number of recesses 3331 may be the same as the number of protrusions 315, and the positions of the multiple recesses 3331 correspond to the positions of the multiple protrusions 315 respectively. In this case, the connection strength between the connecting body 31 and the connecting member 33 is relatively high.

[0055] See also Figure 3 and Figure 4 In some embodiments, the protrusion 315 and the main body 333 both abut against the side wall of the installation box 10.

[0056] After the connection assembly 30 and the installation box 10 are installed in place, the end of the main body 333 near the protrusion 335 will abut the outer wall of the connection hole 11 (the side wall of the installation box 10), thereby positioning the installation of the connection assembly 30. The main body 333 of the present application is made of soft rubber. When the soft rubber (main body 333) abuts the outer wall of the connection hole 11, the abutment strength of the main body 333 on the outer wall of the connection hole 11 is poor, resulting in poor installation and positioning of the connection assembly 30. Moreover, external liquid can easily flow into the connection hole 11 through the gap between the main body 333 and the outer wall of the connection hole 11, and the waterproof effect of the connection structure 100 is poor.

[0057] When a protrusion 315 is provided on the first connecting portion 311 and the protrusion 315 and the body portion 333 jointly abut the outer wall of the connecting hole 11, since the protrusion 315 is made of hard rubber, the protrusion 315 and the body portion 333 can jointly make hard contact with the outer wall of the connecting hole 11. In this case, the connection strength between the connecting assembly 30 and the installation box 10 is relatively high. Furthermore, the protrusion 335 and the body portion 333 effectively position the connecting assembly 30 for installation. Once the connecting assembly 30 is in place, the connecting assembly 30 can be effectively prevented from further extending toward the connecting hole 11. Furthermore, when the protrusion 315 and the body portion 333 make hard contact with the outer wall of the connecting hole 11, there is virtually no gap between the body portion 333 and the sidewall of the connecting hole 11, making it difficult for external liquid to flow into the connecting hole 11 through the gap between the body portion 333 and the outer wall of the connecting hole 11, thereby improving the waterproofing effect of the connecting structure 100.

[0058] See also Figure 3 and Figure 4In some embodiments, the sealing portion 331 includes a plurality of sealing portions 331, and the plurality of sealing portions 331 are sequentially spaced apart along the extension direction of the protrusion 335. For example, the number of sealing portions 331 may be two, three, four, or more. In the case where there are a plurality of sealing portions 331, the plurality of sealing portions 331 all abut against the side wall of the connection hole 11, the connection between the connection component 30 and the inner wall of the connection hole 11 is tighter, the connection strength between the connection component 30 and the installation box 10 is higher, and the waterproof effect of the connection structure 100 can be further enhanced, so that external liquids are not easily able to enter the installation cavity 13.

[0059] See also Figure 3 and Figure 4 In some embodiments, the sealing portion 331 has a closed annular structure. In this case, the sealing portion 331 has a simpler structure and is easier to process. Furthermore, the sealing portion 331 can abut against the inner wall of the connection hole 11 all around, improving the waterproofing of the connection structure 100. In other embodiments, the sealing portion 331 has an intermittent annular structure. In this case, the sealing portion 331 requires less material, saving material.

[0060] See also Figure 3 and Figure 4 In some embodiments, a first boss 314 is formed between the first connecting portion 311 and the second connecting portion 313 , a second boss 336 is formed between the main body portion 333 and the protruding portion 335 , and the first boss 314 cooperates with the second boss 336 .

[0061] The outer diameter of the first connecting portion 311 is greater than the outer diameter of the second connecting portion 313, thereby forming a first boss 314 at the connection between the first connecting portion 311 and the second connecting portion 313. The outer diameter of the main body 333 is greater than the outer diameter of the protrusion 335, thereby forming a second boss 336 at the connection between the main body 333 and the protrusion 335. When the first boss 314 and the second boss 336 cooperate, the connection area between the connector 33 and the connecting body 31 is increased, thereby further strengthening the connection between the connector 33 and the connecting body 31, and preventing the connector 33 from loosening relative to the connecting body 31.

[0062] Furthermore, when the first boss 314 and the second boss 336 are engaged, a stepped surface is formed on one side of the main body 333 of the connecting assembly 30 near the protrusion 335. As the connecting assembly 30 is inserted into the connecting hole 11, the stepped surface can be used to position the connecting assembly 30. When the stepped surface abuts the outer wall of the connecting hole 11, the connecting assembly 30 and the mounting box 10 are properly installed. This simplifies installation of the connecting assembly 30 and the mounting box 10 and effectively avoids misalignment.

[0063] See also Figure 3and Figure 4 Furthermore, in some embodiments, the connecting body 31 also includes a third connecting portion 317 extending from the second connecting portion 313, and the third connecting portion 317 is connected to the side wall of the connecting hole 11 through a sealing adhesive. The outer side wall of the third connecting portion 317 is provided with a wavy pattern, and the wavy pattern is used to enhance the adhesion of the sealing adhesive.

[0064] When the third connecting portion 317 is connected to the side wall of the connecting hole 11 by the sealing adhesive, the connection between the connecting assembly 30 and the installation box 10 is more stable, and the connecting assembly 30 is not easy to get loose relative to the installation box 10. In addition, it is not easy for external liquid to enter the installation box 10 through the gap between the third connecting portion 317 and the side wall of the connecting hole 11. The abutment between the sealing portion 331 of the present application and the side wall of the connecting hole 11 can form a first waterproof structure, and a second waterproof structure can be formed between the third connecting portion 317, the sealing adhesive and the side wall of the connecting hole 11. As a result, the waterproof effect of the connecting structure 100 is better, and it is difficult for external liquid to enter the installation box 10 from the connecting hole 11, thereby avoiding the problem of external liquid affecting the normal operation of the components in the installation box 10.

[0065] See also Figure 3 and Figure 4 Furthermore, in some embodiments, the mounting box 10 is provided with a mounting cavity 13, which is connected to the connecting hole 11; the connecting body 31 also includes a fourth connecting portion extending from the third connecting portion 317, and the fourth connecting portion is a hook, which extends into the mounting cavity 13 to engage with the inner wall of the connecting hole 11.

[0066] The mounting cavity 13 is used to mount the battery, circuit board, and other components of the headset 1000. When the connecting assembly 30 is connected to the mounting box 10, the fourth connecting portion can extend into the mounting cavity 13. The fourth connecting portion is connected to one end of the third connecting portion 317. The fourth connecting portion and the third connecting portion 317 can be an integral structure or a separate structure. When the fourth connecting portion and the third connecting portion 317 are an integral structure, the fourth connecting portion and the third connecting portion 317 can be integrally formed, the processing steps of the connecting assembly 30 are relatively simple, and the connection between the fourth connecting portion and the third connecting portion 317 is relatively stable. When the fourth connecting portion and the third connecting portion 317 are a separate structure, the fourth connecting portion and the third connecting portion 317 can be detachably or non-detachably connected. Removable mounting methods include, but are not limited to, threaded connection, screw connection, or snap connection. Non-detachable mounting methods include, but are not limited to, welding, gluing, or interference fit.

[0067] When the third connecting portion 317 extends into the connecting hole 11, the third connecting portion 317 can drive the fourth connecting portion to extend into the connecting hole 11. When the connecting component 30 is installed in place, the fourth connecting portion can extend into the installation cavity 13. When the fourth connecting portion is a hook, the hook can abut against the inner side wall of the connecting hole 11. At this time, the cooperation between the fourth connecting portion and the inner side wall of the connecting hole 11 can effectively limit the movement of the connecting component 30 in the direction away from the installation box 10. After the connecting component 30 and the installation box 10 are installed in place, the step surface of the main body 333 is used to limit the connecting component 30 from continuing to move toward the installation cavity 13, and the fourth connecting portion is used to limit the movement of the connecting component in the direction away from the installation box 10. As a result, the connection between the connecting component 30 and the installation box 10 is relatively stable, and the connecting component 30 is difficult to fall off relative to the installation box 10.

[0068] See also Figure 3 and Figure 4 In some embodiments, a third cavity 3171 is defined within the third connecting portion 317. The connecting structure 100 further includes a fixing member, a portion of which extends into the third cavity 3171, while another portion of the fixing member presses the third connecting portion 317 against the sidewall of the connecting hole 11. The fixing member may be a pin. After the connecting assembly 30 is installed, the pin extends into the third cavity 3171 and presses the third connecting portion 317 against the sidewall of the connecting hole 11, thereby further strengthening the connection between the third connecting portion 317 and the installation box 10, thereby strengthening the connection between the connecting assembly 30 and the installation box 10.

[0069] See also Figure 3 and Figure 4 In some embodiments, a third cavity 3171 is provided inside the third connecting portion 317, and a fourth cavity is provided inside the fourth connecting portion. The third cavity 3171 and the fourth cavity are connected. The fourth cavity is used to provide a deformation space for the force deformation of the fourth connecting portion during the process of inserting the fourth connecting portion into the connecting hole 11. After the fourth connecting portion is inserted into place again, the fourth connecting portion restores its original shape to engage with the inner wall of the connecting hole 11.

[0070] The outer diameter of the hook (fourth connecting portion) can be larger than the outer diameter of the connecting hole 11, so that when the hook is in the installation cavity 13, the hook can engage with the inner sidewall of the connecting hole 11. When the connecting assembly 30 extends into the connecting hole 11, the hook is squeezed by the sidewall of the connecting hole 11, and the hook can deform toward the fourth cavity. When the third cavity 3171 is connected to the fourth cavity, the deformation of the hook can drive the third connecting portion 317 to deform toward the third cavity 3171. Conversely, the deformation of the third connecting portion 317 can also drive the deformation of the hook. As a result, when the hook is squeezed by the sidewall of the connecting hole 11, the hook is more easily deformed, thereby facilitating the hook's extension into the installation cavity 13. When the hook passes through the connecting hole 11 and enters the installation cavity 13, the hook is no longer squeezed and can return to its original shape to engage with the inner sidewall of the connecting portion. When the third connection portion 317 is provided with the third cavity 3171 and the fourth connection portion is provided with the fourth cavity, the fourth connection portion can be conveniently extended into the installation cavity 13 through the connection hole 11 .

[0071] See also Figure 3 and Figure 4 In some embodiments, a first cavity 3111 is defined within the first connecting portion 311, a second cavity 3131 is defined within the second connecting portion 313, a third cavity 3171 is defined within the third connecting portion 317, and a fourth cavity is defined within the fourth connecting portion. The first cavity 3111, the second cavity 3131, the third cavity 3171, and the fourth cavity are connected, and the fourth cavity is connected to the outside. In this case, the connecting body 31 is easier to form and uses less material, which can save material costs. The overall weight of the connecting assembly 30 is also lower, making the earphone 1000 lighter overall, easier to handle and carry, and providing a better user experience.

[0072] See also Figure 5 The earphone system 10000 of the embodiment of the present application includes the earphone 1000 of the above embodiment and a charging box 3000, which is used to charge the earphone 1000. The charging box 3000 is provided with a charging compartment. When the earphone 1000 needs to be charged, the battery box 101 of the earphone 1000 can be accommodated in the charging compartment, and the charging box 3000 can charge the battery inside the battery box 101.

[0073] In the earphone system 10000 of the embodiment of the present application, the connecting body 31 and the connecting member 33 are integrally formed by double-color injection molding. At least a portion of the connecting member 33 is sleeved on the connecting body 31 and protrudes in a direction away from the connecting body 31 to form an annular sealing portion 331. Compared with the current connection structure 100, the connection structure 100 of the present application does not require an additional sealing ring, and the connection between the connecting component 30 and the installation box 10 is relatively simple, which can effectively save manpower and material costs. In addition, when the connecting component 30 is connected to the installation box 10, the sealing portion 331 abuts the side wall of the connecting hole 11, the connection strength between the connecting component 30 and the installation box 10 is high, and the waterproof effect of the connecting structure 100 is also good. It is difficult for external liquid to flow into the interior of the installation box 10 through the gap between the connecting component 30 and the side wall of the connecting hole 11.
