Description

Technical Field

[0001] The present application relates to the field of earphone technology, and more specifically, to a function box assembly, earphones, and an earphone system. Background Art

[0002] A function box assembly typically includes a function box and buttons on the box, which users can manipulate to adjust the volume, for example. These buttons typically have two connected triggers; pressing one trigger increases the volume, while pressing the other decreases it. However, because users often operate the buttons blindly and the buttons are relatively small, it's easy for the two triggers to interact, causing both the volume increase and volume decrease to be triggered simultaneously, rendering the volume unusable.

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] The function box assembly usually includes a function box and a button set on the function box. The user can adjust the volume, etc. by operating the button. The button usually includes two connected trigger parts. Pressing one trigger part can increase the volume, and pressing the other trigger part can decrease the volume. However, since users usually operate the buttons blindly and the buttons are small in size, it is easy for the two trigger parts to be linked, resulting in the increase and decrease of the volume being triggered at the same time, resulting in the situation where the volume cannot be adjusted. In order to solve this problem, the embodiment of the present application provides a function box assembly 100 ( Figure 2 As shown), earphones 1000 ( Figure 1 shown) and earphone system 10000 ( Figure 6 shown).

[0043] See also Figure 1The earphone 1000 of the embodiment of the present application includes a function box assembly 100. In some embodiments, the earphone 1000 includes a bone conduction earphone 1000 and an air conduction earphone 1000.

[0044] 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.

[0045] The function box assembly 100 includes a battery box assembly 103 and / or a control box assembly 101. In some embodiments, the function box assembly 100 may include a control box assembly 101. The control box assembly 101 may be used to control the power on and off of the headset 1000 and adjust the volume of the headset 1000. In other embodiments, the function box assembly 100 may include a battery box assembly 103. The battery box assembly 103 includes a battery, which is used to power other components of the headset 1000 so that the headset 1000 can operate normally. In still other embodiments, the function box assembly 100 may include a battery box assembly 103 and a control box assembly 101. This application is described by taking the function box assembly 100 as the control box assembly 101 as an example.

[0046] See also Figure 1 In some embodiments, the earphone 1000 further includes an ear hook 500, a back hook 700, and a transducer box assembly 300. The ear hook 500 is used to connect the battery box assembly 103 and the transducer box assembly 300, and to connect the control box assembly 101 and the transducer box assembly 300. The back hook 700 is used to connect the battery box assembly 103 and the control box assembly 101. When the user wears the earphone 1000, the back hook 700 of the earphone 1000 is worn on the head, and the ear hook 500 of the earphone 1000 is worn behind the ear, thereby improving the wearing stability of the earphone 1000. When the user is outdoors or exercising, the earphone 1000 is not likely to fall off. When the user uses the earphone 1000, the transducer box assembly 300 can fit against the human skin, and the transducer box assembly 300 can mechanically vibrate to enable the user to hear the sound.

[0047] See also Figures 2 to 4The function box assembly 100 of the embodiment of the present application includes a box body 10 and a button 30. The box body 10 is provided with a control area 11 for installing the button 30, and the control area 11 is provided with at least two button areas 111. The button 30 is provided in the control area 11, and the button 30 includes at least two triggering parts 31 corresponding to the button areas 111. The box body 10 and the button 30 are connected by a spacer 1132 so that the triggering part 31 is spaced apart from the button area 111; the spacer 1132 is located between two adjacent button areas 111, and the button 30 can rotate around the spacer 1132 so that one of the triggering parts 31 contacts the corresponding button area 111.

[0048] Specifically, the box body 10 is used to install other components of the function box assembly 100. For example, the box body 10 can install components such as a circuit board and a button 30. The control area 11 is used to install control components (for example, the button 30) of the function box assembly 100.

[0049] See also Figures 2 to 4 The button 30 is installed in the control area 11 and is at least partially exposed from the control area 11 to facilitate user operation of the button 30. For example, the user can control the power on and off of the headset 1000 through the button 30, the user can also control the volume of the headset 1000 through the button 30, and the user can also switch audio by operating the button 30. This application uses the button 30 as an example of a volume button 30 that can control the volume of the headset 1000. In this case, the button 30 may include two trigger parts 31, and the control area 11 may include two button areas 111. The two trigger parts 31 correspond to the two button areas 111 respectively. When the user presses one of the trigger parts 31 and the trigger part 31 contacts the corresponding button area 111, the volume of the headset 1000 can be increased. When the user presses the other trigger part 31 and the trigger part 31 contacts the corresponding button area 111, the volume of the headset 1000 can be decreased.

[0050] See also Figure 3 and Figure 4The spacer 1132 can be provided on the case 10 and located between the two key areas 111. That is, in the thickness direction Z of the key 30, the spacer 1132 is also located between the two triggering portions 31. When the key 30 is not subjected to external force, the two triggering portions 31 of the key 30 are spaced apart from the two key areas 111. When the user presses the area between the two triggering portions 31, this area abuts against the spacer 1132, preventing further pressing. This prevents the area between the two triggering portions 31 from being pressed, which could cause the two triggering portions 31 to move in a coordinated manner. When a user applies external force to one of the triggering portions 31, the button 30 can rotate using the spacer portion 1132 as a fulcrum. At this time, the triggering portion 31 subjected to the external force rotates downward to contact the corresponding key area 111, thereby adjusting the volume of the headset 1000. The other triggering portion 31 rotates upward, further away from the corresponding key area 111. In other words, the other triggering portion 31 does not contact the corresponding key area 111, thereby effectively preventing the two triggering portions 31 from synergizing and contacting both key areas 111 at the same time. If both triggering portions 31 contact both key areas 111 at the same time, the button 30 cannot adjust the volume of the headset 1000.

[0051] When the spacer 1132 is located between the two key zones 111, the spacer 1132 can be similar to the fulcrum of a seesaw, and the key 30 can be similar to the seesaw. When one triggering portion 31 is pressed, the spacer 1132 allows that triggering portion 31 to be pressed individually, thereby preventing the other triggering portion 31 from being pressed simultaneously due to a coordinated action. As a result, the pressed triggering portion 31 can accurately trigger the corresponding key zone 111, effectively adjusting the volume of the headset 1000.

[0052] In the function box assembly 100 of the embodiment of the present application, the box body 10 and the button 30 are connected by a spacer 1132, the trigger portion 31 is spaced apart from the button area 111, and the spacer 1132 is located between two adjacent button areas 111. When the user presses one of the trigger portions 31, the button 30 can rotate around the spacer 1132 and make the trigger portion 31 contact the corresponding button area 111 to adjust the function of the headset 1000. When the button 30 rotates around the spacer 1132, the other trigger portion 31 can be spaced apart from the corresponding button area 111. Compared to the current function box assembly 100, the present application is provided with a spacer 1132. The spacer 1132 allows the trigger portion 31 to be pressed separately, and the two trigger portions 31 will not be linked to each other, thereby avoiding the problem of both trigger portions 31 contacting the corresponding button area 111 at the same time, resulting in the inability to adjust the function of the headset 1000.

[0053] The function box assembly 100 will be further described below with reference to the accompanying drawings.

[0054] See also Figures 3 to 5 In some embodiments, the control area 11 is provided with a supporting portion 113, which extends from the side wall of the box body 10 and forms a mounting hole 1131. The supporting portion 113 includes a supporting body 1133 and a spacer 1132 protruding from the supporting body 1133 toward the button 30.

[0055] The supporting portion 113 supports the button 30 and the waterproof member 50 of the function box assembly 100. The mounting hole 1131 allows the button 30 to contact the control elements within the key area 111 to adjust the volume of the earphone 1000. A circuit board is provided within the housing 10, which may include a volume increase switch and a volume decrease switch. The locations of the volume increase and volume decrease switches may correspond to the locations of the mounting holes 1131. The volume increase switch is located within one key area 111, while the volume decrease switch is located within the other key area 111. The button 30 is mounted on the supporting portion 113 and corresponds to the mounting hole 1131. When the trigger portion 31 for increasing the volume of the earphone 1000 is pressed, the button 30 can rotate relative to the spacer 1132. When the trigger portion 31 contacts the volume increase switch within the corresponding key area 111, the volume of the earphone 1000 is effectively increased. When the trigger portion 31 for reducing the volume of the earphone 1000 is pressed, the button 30 can rotate relative to the spacer 1132. When the trigger portion 31 contacts the volume reduction switch in the corresponding button area 111, the volume of the earphone 1000 can be effectively reduced.

[0056] The supporting body 1133 and the spacer 1132 can be an integral structure or a split structure. In the case where the supporting body 1133 and the spacer 1132 are an integral structure, the supporting body 1133 and the spacer 1132 can be integrally formed, the processing steps of the box body 10 are relatively simple, and the connection between the supporting body 1133 and the spacer 1132 is relatively stable. In the case where the supporting body 1133 and the spacer 1132 are split structures, the supporting body 1133 and the spacer 1132 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. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit.

[0057] See also Figures 3 to 5 Furthermore, in some embodiments, the functional box assembly 100 also includes a waterproof component 50, which is arranged in the control area 11 and is integrally molded with the supporting body 1133 by two-color injection molding. The waterproof component 50 covers the opening of the mounting hole 1131 toward the interior of the box body 10.

[0058] The waterproof component 50 is used to prevent external liquid from entering the interior of the box body 10 through the mounting hole 1131, so as to prevent the external liquid from affecting the normal operation of the components inside the box body 10. The waterproof component 50 is connected to the supporting body 1133 and covers the mounting hole 1131. The material of the waterproof component 50 of the present application is different from that of the supporting body 1133. In the case of two-color injection molding between the waterproof component 50 and the supporting body 1133, the connection between the waterproof component 50 and the supporting body 1133 is relatively tight, which can effectively prevent external liquid from entering the interior of the box body 10 through the gap between the waterproof component 50 and the supporting body 1133. The functional box assembly 100 has a good waterproof effect, and the connection strength between the waterproof component 50 and the supporting body 1133 is high, and the waterproof component 50 is not easy to loosen relative to the supporting body 1133.

[0059] See also Figures 3 to 5 In some embodiments, the hardness of the waterproof member 50 is less than the hardness of the box body 10. When the button 30 is installed in the box body 10, the button 30 corresponds to the waterproof member 50. When a trigger portion 31 is pressed to adjust the volume of the earphone 1000, the trigger portion 31 can contact the corresponding volume switch on the circuit board through the waterproof member 50. When the hardness of the waterproof member 50 is less than the hardness of the box body 10, the waterproof member 50 can be deformed when subjected to external force. When the trigger portion 31 is pressed, the trigger portion 31 can apply pressure to the waterproof member 50, so that the waterproof member 50 can be deformed. The trigger portion 31 can contact the corresponding volume switch on the circuit board through the waterproof member 50 to adjust the volume of the earphone 1000. When the hardness of the waterproof component 50 is greater than the hardness of the box body 10, when the trigger part 31 is pressed and the trigger part 31 applies pressure to the waterproof component 50, the waterproof component 50 is not easy to deform, so that the trigger part 31 is difficult to contact the corresponding volume switch on the circuit board through the waterproof component 50. The volume adjustment of the earphone 1000 is not sensitive enough, and the user experience is poor.

[0060] See also Figures 3 to 5 Preferably, in some embodiments, the waterproof component 50 is soft glue and the box body 10 is hard glue. In the case where the box body 10 is hard glue, the strength of the box body 10 is higher and the box body 10 is not easily damaged. At this time, the strength of the supporting body 1133 is also higher. When the trigger part 31 is pressed and the trigger part 31 applies a certain pressure to the supporting body 1133, the supporting body 1133 is not easily deformed or damaged, and the service life of the box body 10 is longer. In the case where the waterproof component 50 is soft glue, the soft glue can be easily deformed, so that the trigger part 31 can contact the corresponding volume switch on the circuit board through the waterproof component 50. The user does not need to apply greater pressure to the trigger part 31 to adjust the volume, and the user experience is better. Among them, the soft glue can be but not limited to rubber, silicone, thermoplastic elastomer or polyvinyl chloride.

[0061] See also Figure 4 and Figure 5 In some embodiments, the number of the spacers 1132 is one, and in the width direction Y of the button 30, the spacer 1132 spans the control area 11. At this time, the structure of the supporting portion 113 is relatively simple, and the processing is relatively simple, and the spacer 1132 can play a good fulcrum role for the button 30. When one trigger portion 31 is pressed, the other trigger portion 31 can be effectively prevented from being pressed in conjunction. In other embodiments, the number of the spacers 1132 is two, and in the width direction Y of the button 30, the two spacers 1132 are spaced apart from each other on the supporting body 1133. At this time, since the waterproof component 50 is an integrated structure, the space between the two spacers 1132 can be used for the waterproof component 50 to be installed therein, that is, the space between the two spacers 1132 is used to make room for the waterproof component 50. The two spacers 1132 of the present application are both spaced apart from the waterproof component 50.

[0062] See also Figures 3 to 5 In some embodiments, the waterproof component 50 includes two connected sub-waterproof components 51. In the thickness direction Z of the key 30, one sub-waterproof component 51 corresponds to one key area 111. When the trigger part 31 contacts the corresponding key area 111, the corresponding sub-waterproof component 51 can be deformed.

[0063] One sub-waterproof member 51 corresponds to one trigger portion 31, and the other sub-waterproof member 51 corresponds to another trigger portion 31. When one trigger portion 31 is pressed, the trigger portion 31 can cause the corresponding sub-waterproof member 51 to deform, so that the trigger portion 31 can contact the volume switch on the corresponding key area 111 through the sub-waterproof member 51 to adjust the volume.

[0064] See also Figure 4 and Figure 5 Specifically, in some embodiments, the sub-waterproof component 51 includes a first waterproof portion 511 and a second waterproof portion 513. The first waterproof portion 511 is located in the mounting hole 1131, and the second waterproof portion 513 surrounds and is connected to the periphery of the first waterproof portion 511. The second waterproof portion 513 is embedded in the supporting body 1133. When the trigger portion 31 applies force to the first waterproof portion 511, the first waterproof portion 511 is deformed by the force, and the second waterproof portion 513 remains fixedly connected to the supporting body 1133.

[0065] When the second waterproof portion 513 is embedded and connected to the supporting body 1133, in the thickness direction Z of the button 30, part of the structure of the second waterproof portion 513 can be connected to the top surface of the supporting body 1133, and another part of the structure of the second waterproof portion 513 can be connected to the bottom surface of the supporting body 1133, and another part of the structure of the second waterproof portion 513 can extend into the interior of the supporting body 1133, so that the connection strength between the second waterproof portion 513 and the supporting body 1133 is high, the waterproof component 50 is not easy to loosen relative to the supporting body 1133, and the waterproof effect of the waterproof component 50 is good, and external liquid is not easy to enter the interior of the box body 10 through the gap between the second waterproof portion 513 (waterproof component 50) and the supporting body 1133.

[0066] The first waterproof portion 511 is configured to deform when under pressure, allowing the trigger portion 31 to contact the volume switch in the keypad 111 through the first waterproof portion 511. The second waterproof portion 513 is configured to be fixedly connected to the supporting body 1133 to prevent the sub-waterproof component 51 from loosening relative to the supporting body 1133 and to prevent external liquid from entering the interior of the case 10 through the mounting hole 1131. When a user applies external force to the trigger portion 31, the trigger portion 31 exerts a certain amount of pressure on the sub-waterproof component 51. At this time, the first waterproof portion 511 can deform toward the interior of the case 10, while the second waterproof portion 513 remains firmly connected to the supporting body 1133. As a result, the sub-waterproof component 51 is not easily loosened relative to the supporting body 1133 even under external force, and the connection between the sub-waterproof component 51 and the supporting body 1133 is relatively tight.

[0067] See also Figure 5 In some embodiments, the supporting body 1133 includes a first protrusion 1135 and a second protrusion 1137. The first protrusion 1135 and the second protrusion 1137 are arranged in a stepped manner in the thickness direction Z of the key 30. The first protrusion 1135 is closer to the outside of the box body 10 than the second protrusion 1137. The spacer 1132 is arranged on the side of the first protrusion 1135 away from the second protrusion 1137.

[0068] Both first protrusion 1135 and second protrusion 1137 extend from the sidewall of box body 10. The area of ​​second protrusion 1137 is larger than that of first protrusion 1135, and second protrusion 1137 is closer to the center of mounting hole 1131. The stepped arrangement of second protrusion 1137 and first protrusion 1135 increases the contact area between support body 1133 and waterproof member 50. After support body 1133 and waterproof member 50 are integrally molded through two-shot injection molding, the connection strength between support body 1133 and waterproof member 50 is high, making it difficult for waterproof member 50 to become loose from support body 1133.

[0069] See also Figure 5In some embodiments, the supporting body 1133 is provided with an injection hole 1139 that at least passes through the second protrusion 1137 , and at least a portion of the second waterproof portion 513 is located in the injection hole 1139 .

[0070] During the two-shot injection molding process of the supporting body 1133 and the waterproof member 50, molten soft glue flows from both the upper and lower surfaces of the supporting body 1133 into the injection holes 1139. The molten soft glue solidifies to form the waterproof member 50. At this point, the second waterproof portion 513 of the waterproof member 50 can form a tight, embedded connection with the supporting body 1133. The second waterproof portion 513 will not deform or separate from the supporting body 1133 under external forces. The connection between the waterproof member 50 and the supporting body 1133 is relatively stable, and external liquids are unlikely to enter the box body 10 through the mounting hole 1131, thereby improving the waterproof performance of the functional box assembly 100. The number of injection holes 1139 can be, but is not limited to, one, two, three, four, or more. When there are multiple injection holes 1139, the connection strength between the second waterproof portion 513 and the supporting body 1133 is relatively high.

[0071] See also Figure 5 Specifically, in some embodiments, the first protrusion 1135 includes an annular protrusion body 11351 and two protruding extensions 11353 extending from the protrusion body 11351 toward the center of the protrusion body 11351, and the spacer 1132 is provided on the protruding extension 11353; the second protrusion 1137 includes an annular first sub-protrusion 11371, an annular second sub-protrusion 11373, and a connecting portion 11361 connecting the first sub-protrusion 11371 and the second sub-protrusion 11373. The second sub-protrusion 11373 is connected to the sub-protrusion 11375. The first sub-protrusion 11371, the connecting sub-protrusion 11375 and the second sub-protrusion 11373 are arranged along the length direction X of the key 30. At least a part of the connecting sub-protrusion 11375 is opposite to the protruding extension portion 11353 in the thickness direction Z of the key 30. The first sub-protrusion 11371, the connecting sub-protrusion 11375 and the second sub-protrusion 11373 are all provided with an injection hole 1139.

[0072] At this time, at least part of the second waterproof part 513 is located in the multiple injection holes 1139, and the second waterproof part 513 and the first sub-protrusion 11371, the connecting sub-protrusion 11375 and the second sub-protrusion 11373 can form a tight embedded connection. The connection between the second waterproof part 513 and the supporting body 1133 is tighter, the waterproof effect of the waterproof part 50 is better, and the waterproof part 50 is not easy to separate from the supporting body 1133.

[0073] See also Figure 5In some embodiments, the injection hole 1139 includes a first injection hole 11391 and a second injection hole 11393. The first injection hole 11391 is provided at the first sub-protrusion 11371 and the second sub-protrusion 11373, and at least a portion of the second waterproof portion 513 is located in the first injection hole 11391; the second injection hole 11393 is provided at the connecting sub-protrusion 11375, and the second injection hole 11393 is located between the two sub-waterproof parts 51, and at least a portion of the connection between the two sub-waterproof parts 51 is located in the second injection hole 11393.

[0074] See also Figure 5 The number of first injection holes 11391 on the first sub-protrusion 11371 can be, but is not limited to, one, two, three, or more. The number of first injection holes 11391 on the second sub-protrusion 11373 can be, but is not limited to, one, two, three, or more. In the present application, the number of first injection holes 11391 on the first sub-protrusion 11371 is the same as the number of first injection holes 11391 on the second sub-protrusion 11373. For example, five first injection holes 11391 are provided on the first sub-protrusion 11371, and five first injection holes 11391 are also provided on the second sub-protrusion 11373. When at least part of the second waterproof portion 513 is located within the plurality of first injection holes 11391, the second waterproof portion 513 is tightly connected to the supporting body 1133, the functional box assembly 100 has a better waterproof effect, and it is difficult for external liquid to enter the interior of the box body 10 from the gap between the waterproof component 50 and the supporting body 1133, and the waterproof component 50 is not easy to separate from the supporting body 1133.

[0075] See also Figure 5 , the number of the second injection holes 11393 can be, but is not limited to, one, two, three or more. The number of the second injection hole 11393 of the present application is one, so that the structure of the supporting body 1133 is relatively simple. In the case where at least part of the connection between the two sub-waterproof parts 51 is located at the second injection hole 11393, the cooperation between the connection and the second injection hole 11393 can effectively prevent the linkage of the two sub-waterproof parts 51. When one trigger part 31 is pressurized, the trigger part 31 can apply a certain pressure to the corresponding sub-waterproof part 51, at which time the sub-waterproof part 51 will undergo a certain deformation. In the case where the connection between the two sub-waterproof parts 51 cooperates with the second injection hole 11393, when the sub-waterproof part 51 is deformed, the other sub-waterproof part 51 cannot follow its common deformation, thereby avoiding the problem of the other sub-waterproof part 51 deforming and accidentally touching the volume switch in the corresponding key area 111, and the mutual interference between the two sub-waterproof parts 51 is small.

[0076] See also Figures 3 to 5Furthermore, in some embodiments, the first waterproof portion 511 includes a first side 5111 and a second side 5113 opposite to each other in the thickness direction Z of the waterproof member 50, the first side 5111 of the first waterproof portion is closer to the outside of the box body 10 than the second side 5113, the first side 5111 of the first waterproof portion includes a mounting column 5112, and the mounting column 5112 is provided with a plug hole 51121; the button 30 includes a first side 33 and a second side 35 opposite to each other in the thickness direction Z of the button 30, the first side 33 of the button is closer to the outside of the box body 10 than the second side 35, and the second side 35 of the button is provided with a connecting column 351, and when the button 30 is installed on the waterproof member 50, the connecting column 351 extends into the plug hole 51121 of the mounting column 5112.

[0077] When the connecting post 351 is inserted into the insertion hole 51121, the connection between the button 30 and the waterproof member 50 is relatively stable, and the button 30 is unlikely to become loose relative to the waterproof member 50. At least a portion of the connecting post 351 can correspond to the volume switch in the key area 111. Therefore, when the trigger portion 31 is pressed, at least a portion of the connecting post 351 can cause the sub-waterproof member 51 to deform. At least a portion of the connecting post 351 can contact the volume switch in the key area 111 through the sub-waterproof member 51, thereby facilitating volume adjustment of the earphone 1000.

[0078] See also Figure 4 and Figure 5 Preferably, in certain embodiments, the center of the plug hole 51121 is located on the length and width mid-planes of the sub-waterproof member 51. In this case, the plug hole 51121 is centered on the sub-waterproof member 51, and the connecting post 351 on the trigger portion 31 can also be centered. When the trigger portion 31 is subjected to external force, the external force is more concentrated on the middle portion of the trigger portion 31, and thus the deformation of the sub-waterproof member 51 is also more concentrated in the middle portion. As a result, on the one hand, the connecting post 351 on the trigger portion 31 can better contact the volume switch of the corresponding key area 111 through the sub-waterproof member 51. On the other hand, the pulling force on the periphery of the sub-waterproof member 51 (the second waterproof portion 513) is also more uniform, which can avoid the problem of some parts being subjected to greater pulling force than other parts, which can easily damage the second waterproof portion 513. When all parts of the second waterproof portion 513 are subjected to uniform force, the service life of the waterproof member 50 can be extended.

[0079] See also Figures 3 to 5In some embodiments, multiple mounting posts 5112 are provided, each of which has multiple insertion holes 51121. Multiple connecting posts 351 are provided, each of which is inserted into each of the insertion holes 51121. This creates multiple connections between the button 30 and the first waterproof portion 511, thereby increasing the strength and stability of the connection between the button 30 and the waterproof member 50 and preventing the button 30 from becoming loose relative to the waterproof member 50.

[0080] See also Figures 3 to 5 In some embodiments, multiple mounting posts 5112 are arranged sequentially along the length direction X or the width direction Y of the waterproof member 50. Adjacent mounting posts 5112 share a sidewall. A notch 51123 is defined in the sidewall of at least one mounting post 5112, extending through the inner and outer sides and communicating with the insertion hole 51121. When the connecting post 351 is plugged into the insertion hole 51121, the notch 51123 allows air inside the insertion hole 51121 to escape, facilitating insertion of the connecting post 351 into the bottom of the insertion hole 51121. This provides greater connection stability between the connecting post 351 and the insertion hole 51121, and further enhances the connection stability between the button 30 and the waterproof member 50.

[0081] See also Figures 3 to 5 Preferably, in some embodiments, on the same sub-waterproof component 51, each mounting column 5112 is provided with a notch 51123, and the extension direction of the plurality of notches 51123 is consistent with the length direction X or the width direction Y of the waterproof component 50.

[0082] In one embodiment, multiple mounting posts 5112 are arranged sequentially along the longitudinal direction X of the waterproof member 50, and the multiple notches 51123 extend in the same direction as the longitudinal direction X of the waterproof member 50. In this case, the multiple notches 51123 are interconnected, and the multiple notches 51123 can generally form a straight line. During the insertion of the connecting post 351 into the insertion hole 51121, the gas inside each insertion hole 51121 enters the notch 51123 formed by the mounting post 5112. The gas in the notch 51123 can then flow through the other notches 51123 and ultimately be discharged outside the waterproof member 50.

[0083] In another embodiment, multiple mounting posts 5112 are arranged sequentially along the width direction Y of the waterproof member 50, and the multiple notches 51123 extend in the same direction as the width direction Y of the waterproof member 50. In this case, the multiple notches 51123 can be interconnected, and the multiple notches 51123 can generally form a straight line. During the insertion of the connecting post 351 into the insertion hole 51121, the gas inside each insertion hole 51121 enters the notch 51123 formed by the mounting post 5112. The gas in the notch 51123 can then flow through the other notches 51123 and ultimately be discharged outside the waterproof member 50.

[0084] A notch 51123 is provided on each mounting column 5112. When the extension direction of the plurality of notches 51123 is consistent with the length direction X or the width direction Y of the waterproof component 50, the gas in the plurality of plug holes 51121 can be discharged to the outside of the waterproof component 50, so that the connection between the connecting column 351 and the plug hole 51121 is more stable, and the connection strength between the button 30 and the waterproof component 50 is higher.

[0085] See also Figure 2 、 Figure 4 and Figure 5 In some embodiments, the first side 33 of the key has a thinned portion 331 located at the junction between the two key areas 111. The thinned portion 331 may be recessed from the first side 33 of the key toward the second side 35 of the key. When a user touches the key 30 blindly, the thinned portion 331 indicates that the location is the middle between the two trigger portions 31. This facilitates the user's determination of the positions of the two trigger portions 31 and allows the user to accurately press the trigger portion 31.

[0086] See also Figure 6 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 of the earphone 1000 can be accommodated in the charging compartment, and the charging box 3000 can charge the battery inside the battery compartment.

[0087] In the headphone system 10000 according to the embodiment of the present application, the housing 10 and the button 30 are connected by a spacer 1132. The trigger portion 31 is spaced apart from the button area 111, and the spacer 1132 is located between two adjacent button areas 111. When a user presses one of the trigger portions 31, the button 30 can rotate around the spacer 1132 and contact the corresponding button area 111 to adjust the function of the headphone 1000. When the button 30 rotates around the spacer 1132, the other trigger portion 31 can be spaced apart from the corresponding button area 111. Compared to the current function box assembly 100, the present application provides a spacer 1132. The spacer 1132 allows the trigger portion 31 to be pressed individually, and the two trigger portions 31 will not interact with each other. This can avoid the problem of both trigger portions 31 contacting the corresponding button area 111 at the same time, resulting in an inability to adjust the function of the headphone 1000.
