[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 2024221343833, filed with the China National Intellectual Property Administration on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of headphone technology, and more specifically, to a functional box assembly, headphones, and headphone system. Background Technology

[0004] A function box assembly typically includes a function box and buttons mounted on it, allowing users to adjust volume and other functions. Buttons usually consist of two connected triggers; pressing one trigger increases the volume, and pressing the other decreases it. However, because users often operate buttons blindly, and the buttons are small, it's easy for the two triggers to work together, causing both volume increase and decrease to be triggered simultaneously, resulting in a situation where the volume cannot be adjusted. Summary of the Invention

[0015] In some embodiments, the support body has an injection hole that extends through the second protrusion, and at least a portion of the second waterproof portion is located within the injection hole.

[0016] In some embodiments, the first protrusion includes an annular protrusion body and two protruding extensions extending from the protrusion body toward the center of the protrusion body, the spacer portion being disposed on the protruding extensions; the second protrusion includes an annular first sub-protrusion, an annular second sub-protrusion, and a connecting sub-protrusion connecting the first sub-protrusion and the second sub-protrusion, the first sub-protrusion, the connecting sub-protrusion and the second sub-protrusion being arranged along the length direction of the button, at least a portion of the connecting sub-protrusion being opposite to the protruding extensions in the thickness direction of the button, and the first sub-protrusion, the connecting sub-protrusion and the second sub-protrusion all having the injection hole.

[0017] In some embodiments, the injection hole includes a first injection hole and a second injection hole, wherein the first injection hole is disposed on the first sub-protrusion and the second sub-protrusion, and at least a portion of the second waterproof part is located in the first injection hole; the second injection hole is disposed on the connecting sub-protrusion, the second injection hole is located between the two sub-waterproof parts, and at least a portion of the connection between the two sub-waterproof parts is located in the second injection hole.

[0018] In some embodiments, the first waterproof portion includes a first side and a second side opposite to each other in the thickness direction of the waterproof component. The first side of the first waterproof portion is closer to the outside of the housing than the second side. The first side of the first waterproof portion includes a mounting post with a insertion hole. The button includes a first side and a second side opposite to each other in the thickness direction of the button. The first side of the button is closer to the outside of the housing than the second side. The second side of the button has a connecting post. When the button is installed on the waterproof component, the connecting post extends into the insertion hole of the mounting post.

[0019] In some embodiments, the center of the insertion hole is located on the length midline and width midline of the sub-waterproof component.

[0020] In some embodiments, the mounting posts include a plurality of posts, each post having a plurality of insertion holes, and the connecting posts include a plurality of posts, each connecting post being inserted into a plurality of insertion holes.

[0026] The headphone system of this application includes the headphones and charging case described in the above embodiments, wherein the charging case is used to charge the headphones.

[0027] In the functional box assembly, earphone, and earphone system of this application, the box body and buttons are connected by a spacer, and the trigger part is spaced apart from the button area, with the spacer located between two adjacent button areas. When a user presses one of the trigger parts, the button can rotate around the spacer and bring the trigger part into contact with the corresponding button area to control the earphone function. When the button rotates around the spacer, the other trigger part can be spaced apart from its corresponding button area. Compared to current functional box assemblies, this application has a spacer, which allows the trigger part to be pressed individually, preventing linkage between the two trigger parts. This avoids the problem of two trigger parts simultaneously contacting the corresponding button areas, which would prevent the earphone function from being adjusted.

[0028] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0042] A function box assembly typically includes a function box and buttons disposed on the function box, allowing users to adjust volume, etc., by manipulating the buttons. The buttons typically include two connected triggers; pressing one trigger increases the volume, and pressing the other decreases the volume. However, since users usually operate the buttons blindly, and the buttons are small, it is easy for the two triggers to move in tandem, causing both volume increase and decrease to be triggered simultaneously, resulting in a situation where the volume cannot be adjusted. To solve this problem, embodiments of this application provide a function box assembly 100 (shown in FIG. 2), an earphone 1000 (shown in FIG. 1), and an earphone system 10000 (shown in FIG. 6).

[0043] Referring to Figure 1, the earphone 1000 of this application embodiment 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] Among them, the bone conduction headphones 1000 use the human skeleton as a medium. The bone conduction headphones 1000 convert sound into mechanical vibrations, which are transmitted through the bones to allow the user to hear. Since the sound from the bone conduction headphones 1000 acts on the bones, long-term use will not significantly affect the user's eardrum, effectively protecting the user's hearing. The air conduction headphones 1000 transmit sound through air vibrations, offering better sound quality and penetration. This application uses the bone conduction headphones 1000 as an example for explanation.

[0045] The functional box assembly 100 includes a battery box assembly 103 and / or a control box assembly 101. In some embodiments, the functional box assembly 100 may include a control box assembly 101. The control box assembly 101 can be used to control the power on / off of the headphones 1000 and adjust the volume of the headphones 1000. In other embodiments, the functional box assembly 100 may include a battery box assembly 103. The battery box assembly 103 includes a battery for powering other components of the headphones 1000 to enable the headphones 1000 to function properly. In still some embodiments, the functional box assembly 100 may include both a battery box assembly 103 and a control box assembly 101. This application uses the control box assembly 101 as an example to illustrate the functional box assembly 100.

[0046] Referring to Figure 1, in some embodiments, the earphone 1000 further includes an ear hook 500, a back hook 700, and a transducer assembly 300. The ear hook 500 is used to connect the battery box assembly 103 and the transducer assembly 300, and to connect the control box assembly 101 and the transducer assembly 300. The back hook 700 is used to connect the battery box assembly 103 and the control box assembly 101. When a user wears the earphone 1000, the back hook 700 is worn on the head, and the ear hook 500 is worn behind the ear, thereby improving the stability of the earphone 1000 and making it less likely to fall off when the user is outdoors or exercising. When a user uses the earphone 1000, the transducer assembly 300 can fit in contact with the skin, and the transducer assembly 300 can enable the user to hear sound through mechanical vibration.

[0047] Please refer to Figures 2 to 4. The functional box assembly 100 of this embodiment includes a box body 10 and a button 30. The box body 10 is provided with a control area 11 for mounting the button 30, and the control area 11 is provided with at least two button areas 111. The button 30 is disposed in the control area 11, and the button 30 includes at least two trigger 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 trigger parts 31 are spaced apart from the button areas 111. The spacer 1132 is located between two adjacent button areas 111, and the button 30 can rotate around the spacer 1132 and make one of the trigger parts 31 contact the corresponding button area 111.

[0048] Specifically, housing 10 is used to mount other components of the function box assembly 100, such as circuit boards and buttons 30. Control area 11 is used to mount control elements (e.g., buttons 30) of the function box assembly 100.

[0049] Please refer to Figures 2 to 4. Button 30 is installed in the control area 11 and is at least partially exposed from the control area 11 to facilitate user operation. For example, the user can control the power on and off of the headphones 1000 using button 30, control the volume of the headphones 1000 using button 30, and switch audio modes using button 30. This application uses a volume button 30 that controls the volume of the headphones 1000 as an example. In this case, 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 trigger part 31, the volume of the headphones 1000 can be increased when the trigger part 31 contacts the corresponding button area 111; when the user presses the other trigger part 31, the volume of the headphones 1000 can be decreased when the trigger part 31 contacts the corresponding button area 111.

[0050] Referring to Figures 3 and 4, the spacer 1132 can be provided on the housing 10 and located between the two button areas 111. That is, in the thickness direction Z of the button 30, the spacer 1132 is also located between the two trigger parts 31. When the button 30 is not subjected to external force, the two trigger parts 31 of the button 30 are spaced apart from the two button areas 111. When the user presses the area between the two trigger parts 31, this area abuts against the spacer 1132, thus preventing the area from being pressed down and avoiding the problem of the two trigger parts 31 being linked due to the area between the two trigger parts 31 being pressed. When the user applies external force to one of the trigger parts 31, the button 30 can rotate using the spacer 1132 as a fulcrum. At this time, the trigger part 31 subjected to external force rotates downwards to contact the corresponding button area 111, thereby adjusting the volume of the headphones 1000. Meanwhile, the other trigger part 31 rotates upwards, moving further away from the corresponding button area 111. That is, the other trigger part 31 will not contact the corresponding button area 111, effectively preventing the two trigger parts 31 from simultaneously contacting both button areas 111. If both trigger parts 31 simultaneously contact both button areas 111, the button 30 cannot adjust the volume of the headphones 1000.

[0051] When the interval 1132 is located between the two button areas 111, the interval 1132 can be analogous to the fulcrum of a seesaw, and the button 30 can be analogous to the seesaw. When one trigger 31 is pressed, the interval 1132 allows that trigger 31 to be pressed individually, avoiding the situation where the other trigger 31 is pressed simultaneously through linkage. Thus, the pressed trigger 31 can accurately trigger the corresponding button area 111 and effectively adjust the volume of the headphone 1000.

[0052] In the functional box assembly 100 of this application embodiment, the box body 10 and the button 30 are connected by a spacer 1132. The trigger part 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 parts 31, the button 30 can rotate around the spacer 1132 and make the trigger part 31 contact the corresponding button area 111 to control the function of the earphone 1000. When the button 30 rotates around the spacer 1132, the other trigger part 31 can be spaced apart from the corresponding button area 111. Compared with the current functional box assembly 100, this application has a spacer 1132, which allows the trigger part 31 to be pressed individually, and the two trigger parts 31 will not be linked, thereby avoiding the problem that the function of the earphone 1000 cannot be adjusted due to the two trigger parts 31 contacting the corresponding button area 111 at the same time.

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

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

[0055] The support portion 113 supports the button 30 and the waterproof component 50 of the function box assembly 100. The mounting hole 1131 allows the button 30 to contact the control element within the button area 111 to adjust the volume of the headphones 1000. The housing 10 contains a circuit board with a volume up switch and a volume down switch. The positions of the volume up switch and the volume down switch correspond evenly to the positions of the mounting holes 1131. The volume up switch is located within one button area 111, and the volume down switch is located within the other button area 111. The button 30 is mounted on the support portion 113 and corresponds to the mounting hole 1131. When the trigger portion 31 for increasing the volume of the headphones 1000 is pressed, the button 30 rotates relative to the spacer portion 1132. When the trigger portion 31 contacts the corresponding volume up switch within the button area 111, the volume of the headphones 1000 is effectively increased. When the trigger part 31 for reducing the volume of the headphones 1000 is pressed, the button 30 can rotate relative to the spacer part 1132. When the trigger part 31 contacts the volume reduction switch in the corresponding button area 111, the volume of the headphones 1000 can be effectively reduced.

[0056] The supporting body 1133 and the spacer 1132 can be an integral or separate structure. When the supporting body 1133 and the spacer 1132 are an integral structure, they can be integrally molded, simplifying the processing of the box body 10 and ensuring a stable connection. When the supporting body 1133 and the spacer 1132 are separate structures, they can be detachably or non-detachably connected. Detachable installation methods include, but are not limited to, threaded connections, screw connections, or snap-fit ​​connections. Non-detachable installation methods include, but are not limited to, welding, gluing, or interference fits.

[0057] Please refer to Figures 3 to 5. Further, in some embodiments, the functional box assembly 100 also includes a waterproof component 50, which is disposed in the control area 11 and integrally molded with the support body 1133 by two-color injection molding. The waterproof component 50 covers the opening of the mounting hole 1131 facing the inside of the box body 10.

[0058] The waterproof component 50 is used to prevent external liquids from entering the interior of the housing 10 through the mounting hole 1131, so as to avoid the external liquids affecting the normal operation of the components inside the housing 10. The waterproof component 50 is connected to the support body 1133 and covers the mounting hole 1131. The material of the waterproof component 50 in this application is different from the material of the support body 1133. When the waterproof component 50 and the support body 1133 are integrally molded with two-color injection molding, the connection between the waterproof component 50 and the support body 1133 is relatively tight, which can effectively prevent external liquids from entering the interior of the housing 10 through the gap between the waterproof component 50 and the support body 1133. The waterproof effect of the functional housing assembly 100 is better, and the connection strength between the waterproof component 50 and the support body 1133 is high, so the waterproof component 50 is not easy to loosen relative to the support body 1133.

[0059] Please refer to Figures 3 to 5. In some embodiments, the hardness of the waterproof component 50 is less than the hardness of the housing 10. When the button 30 is installed on the housing 10, the button 30 corresponds to the waterproof component 50. When a trigger portion 31 is pressed to adjust the volume of the headphones 1000, the trigger portion 31 can contact the corresponding volume switch on the circuit board through the waterproof component 50. When the hardness of the waterproof component 50 is less than the hardness of the housing 10, the waterproof component 50 can deform under external force. When the trigger portion 31 is pressed, the trigger portion 31 can apply pressure to the waterproof component 50, thereby deforming the waterproof component 50. The trigger portion 31 can then contact the corresponding volume switch on the circuit board through the waterproof component 50 to adjust the volume of the headphones 1000. When the hardness of the waterproof component 50 is greater than that of the housing 10, and the trigger part 31 is pressed and applies pressure to the waterproof component 50, the waterproof component 50 is not easily deformed. As a result, the trigger part 31 has difficulty contacting the corresponding volume switch on the circuit board through the waterproof component 50, and the volume adjustment of the headphones 1000 is not sensitive enough, resulting in a poor user experience.

[0060] Referring to Figures 3 to 5, preferably, in some embodiments, the waterproof component 50 is made of soft rubber, and the housing 10 is made of hard rubber. When the housing 10 is made of hard rubber, its strength is higher, and it is less prone to damage. In this case, the support body 1133 also has higher strength. When the trigger part 31 is pressed, and the trigger part 31 applies a certain pressure to the support body 1133, the support body 1133 is less prone to deformation and damage, resulting in a longer service life for the housing 10. When the waterproof component 50 is made of soft rubber, the soft rubber is easily deformable, thus facilitating contact between the trigger part 31 and the corresponding volume switch on the circuit board. The user does not need to apply significant pressure to the trigger part 31 to adjust the volume, resulting in a better user experience. The soft rubber can be, but is not limited to, rubber, silicone, thermoplastic elastomers, or polyvinyl chloride, etc.

[0061] Referring to Figures 4 and 5, in some embodiments, there is one spacer 1132, which spans the control area 11 in the width direction Y of the button 30. In this case, the structure of the support 113 is relatively simple and easy to manufacture, and the spacer 1132 can provide a good fulcrum for the button 30, effectively preventing the other trigger 31 from being pressed simultaneously when one trigger 31 is pressed. In other embodiments, there are two spacers 1132, which are spaced apart on the support body 1133 in the width direction Y of the button 30. In this case, since the waterproof component 50 is an integral structure, the gap between the two spacers 1132 can be used to accommodate the waterproof component 50, that is, the gap between the two spacers 1132 is used to make room for the waterproof component 50. In this application, both spacers 1132 are spaced apart from the waterproof component 50.

[0062] Please refer to 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 button 30, one sub-waterproof component 51 corresponds to one button area 111. When the trigger part 31 contacts the corresponding button area 111, the corresponding sub-waterproof component 51 can deform.

[0063] One sub-waterproof component 51 corresponds to one trigger part 31, and another sub-waterproof component 51 corresponds to another trigger part 31. When a trigger part 31 is pressed, the trigger part 31 can drive the corresponding sub-waterproof component 51 to deform, so that the trigger part 31 can contact the volume switch on the corresponding button area 111 through the sub-waterproof component 51 to realize volume adjustment.

[0064] Please refer to Figures 4 and 5. Specifically, in some embodiments, the sub-waterproof component 51 includes a first waterproof part 511 and a second waterproof part 513. The first waterproof part 511 is located in the mounting hole 1131, and the second waterproof part 513 surrounds and is connected to the periphery of the first waterproof part 511. The second waterproof part 513 is embedded and connected to the support body 1133. When the trigger part 31 applies force to the first waterproof part 511, the first waterproof part 511 deforms under force, and the second waterproof part 513 remains fixedly connected to the support body 1133.

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

[0066] The first waterproof part 511 is designed to deform under pressure, allowing the trigger part 31 to contact the volume switch of the button area 111 through the first waterproof part 511. The second waterproof part 513 is designed to be fixedly connected to the support body 1133 to prevent the sub-waterproof part 51 from becoming loose relative to the support body 1133, and also to prevent external liquid from entering the housing 10 through the mounting hole 1131. When the user applies external force to the trigger part 31, the trigger part 31 will apply a certain pressure to the sub-waterproof part 51. At this time, the first waterproof part 511 can deform to a certain extent towards the housing 10, while the second waterproof part 513 will still be firmly connected to the support body 1133. Therefore, the sub-waterproof part 51 is not easy to become loose relative to the support body 1133 under external force, and the connection between the sub-waterproof part 51 and the support body 1133 is relatively tight.

[0067] Please refer to 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 button 30. The first protrusion 1135 is closer to the outside of the housing 10 than the second protrusion 1137. The spacer 1132 is provided on the side of the first protrusion 1135 away from the second protrusion 1137.

[0068] Both the first protrusion 1135 and the second protrusion 1137 extend from the side wall of the box body 10. The area of ​​the second protrusion 1137 is larger than that of the first protrusion 1135, and the second protrusion 1137 is closer to the center of the mounting hole 1131. When the second protrusion 1137 and the first protrusion 1135 are arranged in a stepped shape, the contact area between the support body 1133 and the waterproof component 50 is larger. After the support body 1133 and the waterproof component 50 are integrally molded in two colors, the connection strength between the support body 1133 and the waterproof component 50 is higher, and the waterproof component 50 is not easy to loosen relative to the support body 1133.

[0069] Please refer to Figure 5. In some embodiments, the supporting body 1133 is provided with an injection hole 1139 that penetrates at least the second protrusion 1137, and at least a portion of the second waterproof part 513 is located within the injection hole 1139.

[0070] During the two-color injection molding process of the support body 1133 and the waterproof component 50, molten soft glue flows from both the upper and lower surfaces of the support body 1133 into the injection hole 1139. After the molten soft glue solidifies, it forms the waterproof component 50. At this time, the second waterproof part 513 of the waterproof component 50 can form a tight embedded connection with the support body 1133. The second waterproof part 513 will not deform under external force, nor will it detach from the support body 1133. The connection between the waterproof component 50 and the support body 1133 is relatively stable, and external liquids are not easily allowed to enter the box 10 through the mounting hole 1131. The waterproof effect of the functional box assembly 100 is good. 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 part 513 and the support body 1133 is higher.

[0071] Referring to 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, with a spacer 1132 disposed on the protruding extensions 11353; the second protrusion 1137 includes an annular first sub-protrusion 11371, an annular second sub-protrusion 11373, and a connection to the first sub-protrusion 11371. 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 button 30. At least a portion of the connecting sub-protrusion 11375 is opposite to the protruding extension 11353 in the thickness direction Z of the button 30. The first sub-protrusion 11371, the connecting sub-protrusion 11375, and the second sub-protrusion 11373 are all provided with injection holes 1139.

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

[0073] Please refer to Figure 5. In some embodiments, the injection hole 1139 includes a first injection hole 11391 and a second injection hole 11393. The first injection hole 11391 is disposed on the first sub-protrusion 11371 and the second sub-protrusion 11373. At least a portion of the second waterproof part 513 is located in the first injection hole 11391. The second injection hole 11393 is disposed on the connecting sub-protrusion 11375. The second injection hole 11393 is located between the two sub-waterproof parts 51. At least a portion of the connection between the two sub-waterproof parts 51 is located within the second injection hole 11393.

[0074] Referring to Figure 5, the number of first injection holes 11391 on the first sub-protrusion 11371 may be, but is not limited to, one, two, three or more, and the number of first injection holes 11391 on the second sub-protrusion 11373 may be, but is not limited to, one, two, three or more. In this 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, the first sub-protrusion 11371 is provided with five first injection holes 11391, and the second sub-protrusion 11373 is also provided with five first injection holes 11391. When at least a portion of the second waterproof part 513 is located within a plurality of first injection holes 11391, the connection between the second waterproof part 513 and the support body 1133 is relatively tight, the waterproof effect of the functional box assembly 100 is better, external liquid is difficult to enter the box 10 through the gap between the waterproof part 50 and the support body 1133, and the waterproof part 50 is also not easy to detach from the support body 1133.

[0075] Referring to Figure 5, the number of second injection holes 11393 can be, but is not limited to, one, two, three, or more. This application uses only one second injection hole 11393, resulting in a simpler structure supporting the body 1133. When at least a portion of the connection between the two sub-waterproof components 51 is located within the second injection hole 11393, the engagement between the connection and the second injection hole 11393 effectively prevents the two sub-waterproof components 51 from interlocking. When one trigger 31 is pressed, the trigger 31 can apply a certain pressure to the corresponding sub-waterproof component 51, causing it to deform. With the connection between the two sub-waterproof components 51 engaging with the second injection hole 11393, when one sub-waterproof component 51 deforms, the other sub-waterproof component 51 cannot deform along with it, thus preventing the other sub-waterproof component 51 from deforming and accidentally triggering the volume switch in the corresponding button area 111. The mutual interference between the two sub-waterproof components 51 is minimal.

[0076] Please refer to Figures 3 to 5. Further, in some embodiments, the first waterproof part 511 includes a first side 5111 and a second side 5113 opposite to each other in the thickness direction Z of the waterproof component 50. The first side 5111 of the first waterproof part is closer to the outside of the housing 10 than the second side 5113. The first side 5111 of the first waterproof part includes a mounting post 5112, and the mounting post 5112 is provided with a insertion 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 housing 10 than the second side 35. The second side 35 of the button is provided with a connecting post 351. When the button 30 is installed on the waterproof component 50, the connecting post 351 extends into the insertion hole 51121 of the mounting post 5112.

[0077] With the connecting post 351 inserted into the insertion hole 51121, the connection between the button 30 and the waterproof component 50 is relatively stable, and the button 30 is not easily loosened relative to the waterproof component 50. At least a portion of the connecting post 351 can correspond to the volume switch of the button area 111, so that when the trigger part 31 is pressed, at least a portion of the connecting post 351 can cause the sub-waterproof component 51 to deform, and at least a portion of the connecting post 351 can touch the volume switch of the button area 111 through the sub-waterproof component 51, thereby facilitating the adjustment of the headphone 1000 volume.

[0078] Referring to Figures 4 and 5, preferably, in some embodiments, the center of the insertion hole 51121 is located on the midline of the length and the midline of the width of the sub-waterproof component 51. In this case, the insertion hole 51121 is centrally located on the sub-waterproof component 51, and the connecting post 351 on the trigger part 31 can also be centrally located. When the trigger part 31 is subjected to external force, the external force is more concentrated in the middle part of the trigger part 31, thus the deformation of the sub-waterproof component 51 is also more concentrated in the middle part. Therefore, on the one hand, the connecting post 351 on the trigger part 31 can better contact the volume switch of the corresponding button area 111 through the sub-waterproof component 51; on the other hand, the tensile force on the periphery of the sub-waterproof component 51 (the second waterproof part 513) is more uniform, avoiding the problem that some parts are subjected to greater tensile force than others, leading to easy damage to the second waterproof part 513. With uniform force on all parts of the second waterproof part 513, the service life of the waterproof component 50 can be extended.

[0079] Referring to Figures 3 to 5, in some embodiments, there are multiple mounting posts 5112, each with multiple insertion holes 51121. There are also multiple connecting posts 351, each inserted into one of the multiple insertion holes 51121. In this case, multiple connection points are formed between the button 30 and the first waterproof part 511, resulting in a stronger connection between the button 30 and the waterproof component 50, better connection stability, and further prevention of the button 30 from becoming loose relative to the waterproof component 50.

[0080] Referring to Figures 3 to 5, in some embodiments, multiple mounting posts 5112 are arranged sequentially along the length direction X or width direction Y of the waterproof component 50. Adjacent mounting posts 5112 share a sidewall, and at least one mounting post 5112 has a notch 51123 that penetrates the inner and outer sides and communicates with the insertion hole 51121. When the connecting post 351 is inserted into the insertion hole 51121, the notch 51123 is used to allow gas inside the insertion hole 51121 to escape, so that the connecting post 351 can be inserted into the bottom of the insertion hole 51121. The connection stability between the connecting post 351 and the insertion hole 51121 is good, and the connection stability between the button 30 and the waterproof component 50 is also good.

[0081] Please refer to Figures 3 to 5. Preferably, in some embodiments, each mounting post 5112 on the same sub-waterproof component 51 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, a plurality of mounting posts 5112 are arranged sequentially along the length X of the waterproof component 50, and a plurality of notches 51123 extend in the same direction as the length X of the waterproof component 50. In this case, the plurality of notches 51123 can communicate with each other, and can approximately form a straight line. During the insertion of the connecting post 351 into the insertion hole 51121, gas inside each insertion hole 51121 enters the notch 51123 formed by the mounting post 51122. The gas in the notch 51123 can flow through the other notches 51123 and eventually exit outside the waterproof component 50.

[0083] In another embodiment, a plurality of mounting posts 5112 are arranged sequentially along the width direction Y of the waterproof component 50, and a plurality of notches 51123 extend in the same direction as the width direction Y of the waterproof component 50. In this case, the plurality of notches 51123 can communicate with each other, and can approximately form a straight line. During the insertion of the connecting post 351 into the insertion hole 51121, gas inside each insertion hole 51121 enters the notch 51123 formed by the mounting post 51122. The gas in the notch 51123 can flow through other notches 51123 and eventually exit outside the waterproof component 50.

[0084] Each mounting post 5112 is provided with a notch 51123. When the extension direction of multiple notches 51123 is consistent with the length direction X or width direction Y of the waterproof component 50, it is convenient for the gas in multiple insertion holes 51121 to be discharged to the outside of the waterproof component 50. As a result, the connection between the connecting post 351 and the insertion hole 51121 is more stable, and the connection strength between the button 30 and the waterproof component 50 is higher.

[0085] Please refer to Figures 2, 4, and 5. In some embodiments, the first side 33 of the button has a thinning portion 331, which is located at the connection between the two button areas 111. The thinning portion 331 is recessed from the first side 33 of the button toward the second side 35 of the button. When the user blindly touches the button 30, if the user touches the thinning portion 331, the user can know that this is the middle position of the two trigger parts 31, which makes it easier for the user to judge the position of the two trigger parts 31 and to accurately press the trigger parts 31.

[0086] Please refer to Figure 6. The headphone system 10000 of this application embodiment includes the headphone 1000 and charging case 3000 of the above embodiment. The charging case 3000 is used to charge the headphone 1000. The charging case 3000 is provided with a charging compartment. When the headphone 1000 needs to be charged, the battery compartment of the headphone 1000 can be accommodated in the charging compartment, and the charging case 3000 can charge the battery inside the battery compartment.

[0087] In the headphone system 1000 of this application embodiment, the housing 10 and the button 30 are connected by a spacer 1132. The trigger part 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 parts 31, the button 30 rotates around the spacer 1132, causing the trigger part 31 to contact the corresponding button area 111, thereby controlling the function of the headphone 1000. When the button 30 rotates around the spacer 1132, the other trigger part 31 can be spaced apart from its corresponding button area 111. Compared to the current function housing assembly 100, this application provides a spacer 1132, which allows the trigger part 31 to be pressed individually, preventing simultaneous contact between the two trigger parts 31 and thus avoiding the problem of the headphone 1000's function being unable to be adjusted.

[0088] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
