Description

Transducer assembly, headphones, and headphone system Technical Field

[0001] This application relates to the field of headphone technology, and more specifically, to a transducer, headphones, and headphone system. Background Technology

[0002] The transducer assembly of headphones enables users to hear sound. A deformable, waterproof component is typically located between the transducer housing and the buttons. This waterproof component serves two purposes: firstly, it prevents external liquids from entering the transducer housing; secondly, when the user presses the button, the waterproof component deforms to trigger a switch on the circuit board inside the transducer housing, allowing functions such as answering calls or adjusting the headphone volume. However, during swimming or diving, the high water pressure can cause the buttons to be subjected to pressure from the water flow. The button transmits this pressure to the waterproof component, causing it to deform and trigger the switch on the circuit board. This poses a risk of accidental activation of the switch, affecting the actual use of the headphones.

[0003] Summary of the Invention

The waterproof component is located in the mounting area and is integrally molded with the transducer box using a two-color injection molding process. The waterproof component covers the opening in the mounting area facing the interior of the transducer box. The button is mounted in the mounting area and connected to the waterproof component, and the button is exposed from the mounting area to the exterior of the transducer box.

[0006] In some embodiments, the mounting area is provided with a support portion that extends from the side wall of the transducer box and forms a mounting hole, and the waterproof component is integrally molded with the support portion using two-color injection molding.

[0007] In some embodiments, the hardness of the waterproof component is less than the hardness of the transducer box.

[0008] In some embodiments, the waterproof component is made of soft rubber, and the transducer box is made of hard rubber.

[0009] In some embodiments, the waterproof component includes a first waterproof part and a second waterproof part. The first waterproof part is located inside the mounting hole, and the second waterproof part surrounds and is connected to the periphery of the first waterproof part. The second waterproof part is embedded and connected to the support part and is connected to the inner wall of the transducer box. When the button is pressed, the first waterproof part deforms under force, and the second waterproof part remains connected to the support part and the inner wall of the transducer box.

[0010] In some embodiments, the support portion includes a first protrusion and a second protrusion, the first protrusion and the second protrusion being arranged in a stepped manner in the thickness direction of the button, the first protrusion being closer to the outside of the transducer box than the second protrusion.

[0011] In some embodiments, the second protrusion has a through injection hole, and at least a portion of the second waterproof portion is located within the injection hole, so that the second waterproof portion is embedded in the second protrusion.

[0012] In some embodiments, the supporting portion has a support portion on the side facing the transducer box, the support portion is arranged around the mounting hole and protrudes into the transducer box relative to the second protrusion.

[0013] In some embodiments, the first protrusion has a protrusion at its periphery facing the second protrusion, and a recess is formed on the outer side of the first waterproof portion, the recess engaging with the protrusion.

[0014] In some embodiments, the inner wall of the transducer box is provided with a groove, at least a portion of the second waterproof part is located in the groove, and the second waterproof part forms a concave-convex fit with the inner wall of the transducer box.

[0015] In some embodiments, in the thickness direction of the waterproof component, the first waterproof portion includes a first side and a second side facing away from each other, the first side of the first waterproof portion being closer to the outside of the transducer box than the second side, and the first side of the first waterproof portion including a mounting post with a insertion hole; in the thickness direction of the waterproof component, the button includes a first side and a second side facing away from each other, the first side of the button being closer to the outside of the transducer box than the second side, and the second side of the button having a connecting post extending into the insertion hole of the mounting post.

[0016] In some embodiments, the center of the insertion hole is located on the length midline and width midline of the first waterproof part.

[0017] 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.

[0018] In some embodiments, a plurality of mounting posts are arranged sequentially along the length or width of the waterproof component, adjacent mounting posts share a sidewall, and at least one mounting post has a notch in its sidewall that penetrates the inner and outer sides and communicates with the insertion hole.

[0019] In some embodiments, each of the mounting posts is provided with a notch, and the extension direction of the plurality of notches is consistent with the length direction or width direction of the waterproof component.

[0020] In some implementations, the button is clearance-fitted with the mounting area.

[0021] In some embodiments, the transducer assembly further includes a circuit board and a switch housed within the transducer box. The switch is mounted on the circuit board and corresponds to the waterproof component. When the button is pressed and causes the waterproof component to deform, the waterproof component comes into contact with the switch, thereby triggering the switch.

[0022] In some embodiments, a trigger protrusion is provided on the second side of the first waterproof portion of the waterproof component. In the thickness direction of the waterproof component, the trigger protrusion corresponds to the switch and is used to abut against the switch.

[0026] In the transducer assembly, earphone, and earphone system of this application, the waterproof component is located in the mounting area and integrally molded with the transducer box using dual-color injection molding. The button is mounted in the mounting area and connected to the waterproof component. When a user wears the earphone while swimming or diving, and the button is subjected to a certain water pressure, the button will transmit this pressure to the waterproof component. Due to the high connection strength between the periphery of the waterproof component and the transducer box, the periphery of the waterproof component can be tightened by the transducer box. The waterproof component is not easily deformed when subjected to pressure applied by the button, thus the button will not trigger the switch on the circuit board of the transducer assembly through the waterproof component. This application can effectively avoid the problem of accidental activation of the switch on the circuit board of the transducer assembly under high water pressure, resulting in a better user experience.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] The transducer assembly of an earphone is used to enable the user to hear sound. A deformable waterproof component is typically provided between the transducer housing and the button of the transducer assembly. This waterproof component prevents external liquids from entering the transducer housing; furthermore, when the user presses the button, the waterproof component deforms to trigger a switch on the circuit board inside the transducer housing, thereby enabling functions such as answering calls or adjusting the earphone volume. However, during swimming or diving, due to excessive water pressure, the button is subjected to pressure from the water flow. The button transmits this pressure to the waterproof component, causing it to deform and trigger the switch on the circuit board. This poses a risk of accidental activation of the switch, affecting the actual use of the earphone. To address this problem, this application provides a transducer assembly 100 (shown in FIG. 2), an earphone 1000 (shown in FIG. 1), and an earphone system 10000 (shown in FIG. 7).

[0045] Please refer to Figures 1 and 2. The headphones 1000 of this embodiment include a transducer assembly 100. In some embodiments, the headphones 1000 include bone conduction headphones 1000 and air conduction headphones 1000.

[0046] 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.

[0047] The transducer component 100 of this application is designed to fit in contact with human skin. When the headphones 1000 are in use, the transducer component 100 can generate vibrations, which are transmitted through the human skeleton, allowing the user to hear sound. The headphones 1000 of this application also includes a function box assembly 300, which is electrically connected to the transducer component 100. The function box assembly 300 may include a battery box assembly 303 and / or a control box assembly 301. The control box assembly 301 can be used to control the power on / off of the headphones 1000 and adjust the volume of the headphones 1000. The battery box assembly 303 includes a battery that powers other components of the headphones 1000 to enable the headphones 1000 to function properly.

[0048] Referring to Figure 1, in some embodiments, the earphone 1000 further includes an ear hook 500 and a back hook 700. The ear hook 500 is used for electrically connecting the battery box assembly 303 and the transducer assembly 100, and for electrically connecting the control box assembly 301 and the transducer assembly 100. The back hook 700 is used for electrically connecting the battery box assembly 303 and the control box assembly 301. When a 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 stability of wearing the earphone 1000 and making it less likely to fall off when the user is outdoors or exercising.

[0049] Referring to Figures 2 to 4, the transducer assembly 100 of this embodiment includes a transducer box 10, a deformable waterproof component 30, and a button 50. The transducer box 10 has a mounting cavity 15, and a mounting area 11 communicating with the mounting cavity 10. The waterproof component 30 is located in the mounting area 11 and integrally molded with the transducer box 10 using two-color injection molding. The waterproof component 30 covers the opening of the mounting area 11 facing the interior of the transducer box 10. The button 50 is mounted in the mounting area 11 and connected to the waterproof component 30, with the button 50 exposed from the mounting area 11 to the outside of the transducer box 10.

[0050] Referring to Figure 2, specifically, the mounting cavity 15 is used to mount other components of the transducer assembly 100, such as the vibrating component and microphone of the transducer assembly 100. The mounting area 11 is used to mount the waterproof component 30 and the button 50.

[0051] Please refer to Figures 2 to 4. Button 50 is installed in the mounting area 11 and is at least partially exposed from the mounting area 11 to facilitate user operation. For example, the user can control the power on and off of the headset 1000 via button 50, adjust the volume of the headset 1000 via button 50, and answer calls, play music, pause music, and switch songs via button 50. Button 50 is connected to the waterproof component 30. When button 50 is pressed, it causes the waterproof component 30 to deform. When the waterproof component 30 deforms and contacts the switch 90 on the circuit board 70 of the transducer assembly 100, the switch 90 on the circuit board 70 of the transducer assembly 100 is triggered, thereby adjusting the function of the headset 1000.

[0052] Referring to Figure 2, in some embodiments, the button 50 and the mounting area 11 are clearance-fitted, meaning there may be a gap between the button 50 and the sidewall of the mounting area 11. When external liquid enters the space between the button 50 and the waterproof component 30 through the space between the button 50 and the sidewall of the mounting area 11, since the waterproof component 30 and the transducer box 10 are integrally molded using dual-color injection molding, the external liquid will not enter the mounting cavity 15 through the waterproof component 30. During the movement or swinging of the earphone 1000, the liquid between the button 50 and the waterproof component 30 can flow out through the gap to the outside of the transducer assembly 100. The gap between the button 50 and the sidewall of the mounting area 11 facilitates the drainage of liquid from the mounting area 11.

[0053] Please refer to Figures 3 to 5. The waterproof component 30 is used to prevent external liquid from entering the mounting cavity 15 from the mounting area 11, so as to avoid the external liquid affecting the normal operation of the components in the mounting cavity 15. The waterproof component 30 is connected to the side wall of the mounting area 11. The material of the waterproof component 30 in this application is different from the material of the transducer box 10. When the waterproof component 30 and the transducer box 10 are integrally molded with two-color injection molding, the connection between the waterproof component 30 and the transducer box 10 is relatively tight, which can effectively prevent external liquid from entering the mounting cavity 15 through the gap between the waterproof component 30 and the transducer box 10. The waterproof effect of the transducer assembly 100 is better. In addition, the connection strength between the periphery of the waterproof component 30 and the transducer box 10 is high. The periphery of the waterproof component 30 can be tightened by the transducer box 10. Under small external forces, the waterproof component 30 is not easy to deform in the direction of the mounting cavity 15.

[0054] For example, the earphone 1000 of this application can be a swimming earphone 1000. When the user wears the earphone 1000 while swimming or diving, the button 50 is subjected to a certain water pressure. The button 50 will transmit this pressure to the waterproof component 30 (usually this pressure is less than the pressure pressed by the user). Since the periphery of the waterproof component 30 is tightened by the transducer box 10, the waterproof component 30 will hardly deform when subjected to this pressure. This can prevent the button 50 from triggering the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30. The switch 90 on the circuit board 70 of the transducer assembly 100 can effectively avoid the risk of accidental activation, and the user experience is better. When a user needs to adjust the function of the headphones 1000 via button 50, the user can apply greater pressure to button 50. At this time, button 50 transmits the pressure to the waterproof component 30. When the waterproof component 30 is subjected to this pressure, it can deform and contact the switch 90 on the circuit board 70 of the transducer assembly 100. Thus, button 50 can trigger the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30 to adjust the function of the headphones 1000.

[0055] In the transducer assembly 100 of this application embodiment, the waterproof component 30 is located in the mounting area 11 and integrally molded with the transducer box 10 using dual-color injection molding. The button 50 is installed in the mounting area 11 and connected to the waterproof component 30. When a user wears headphones 1000 while swimming or diving, and the button 50 is subjected to a certain water pressure, the button 50 will transmit this pressure to the waterproof component 30. Because the connection strength between the periphery of the waterproof component 30 and the transducer box 10 is high, the periphery of the waterproof component 30 can be tightened by the transducer box 10. The waterproof component 30 is not easily deformed when subjected to pressure applied by the button 50, so the button 50 will not trigger the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30. This application can effectively avoid the problem of accidental activation of the switch 90 on the circuit board 70 of the transducer assembly 100 under high water pressure, resulting in a better user experience.

[0056] The transducer assembly 100 will be further described below with reference to the accompanying drawings.

[0057] Please refer to Figures 3 to 5. In some embodiments, the mounting area 11 is provided with a support portion 111. The support portion 111 extends from the side wall of the transducer box 10 and forms a mounting hole 1111. The waterproof component 30 and the support portion 111 are integrally molded in two colors by injection molding.

[0058] The support portion 111 is used to support the waterproof component 30 and the button 50. When the waterproof component 30 and the support portion 111 are integrally molded by two-color injection molding, the connection between the waterproof component 30 and the support portion 111 is relatively tight, and external liquid is not easy to enter the transducer box 10 through the mounting hole 1111. In addition, the connection strength between the periphery of the waterproof component 30 and the support portion 111 is high, and the periphery of the waterproof component 30 can be tightened by the support portion 111. When the user wears the headphones 1000 while swimming or diving, the problem of the waterproof component 30 being deformed by the pressure of the button 50 and accidentally activating the switch 90 on the circuit board 70 of the transducer assembly 100 can be avoided.

[0059] Please refer to Figures 3 and 5. In some embodiments, the transducer assembly 100 further includes a circuit board 70 and a switch 90 housed in the mounting cavity 15. The switch 90 is mounted on the circuit board 70 and corresponds to the waterproof component 30. When the button 50 is pressed and causes the waterproof component 30 to deform, the waterproof component 30 comes into contact with the switch 90, thereby triggering the switch 90.

[0060] Mounting hole 1111 communicates with mounting cavity 15. Mounting hole 1111 allows switch 90 to protrude from mounting hole 1111. Switch 90 corresponds to waterproof component 30. When the user needs to adjust the function of headphone 1000, the user presses button 50. Button 50 transmits pressure to waterproof component 30. Waterproof component 30 can deform into transducer box 10. When waterproof component 30 deforms, it can contact switch 90, thereby triggering switch 90 on circuit board 70.

[0061] Referring to Figures 3 to 5, in some embodiments, the hardness of the waterproof component 30 is less than the hardness of the transducer box 10. This allows the waterproof component 30 to deform easily under external force. When the user presses button 50, button 50 applies pressure to the waterproof component 30, causing it to deform and trigger switch 90. The user does not need to apply significant force to button 50 to trigger switch 90, resulting in better sensitivity of the transducer assembly 100 and a better user experience. However, when the hardness of the waterproof component 30 is greater than that of the transducer box, the waterproof component 30 is less likely to deform when the user presses button 50, making it difficult for it to contact switch 90. This results in less sensitive adjustment of the transducer assembly 100 and a poorer user experience.

[0062] Please refer to Figures 3 to 5. In some embodiments, the waterproof component 30 is made of soft rubber, and the transducer box 10 is made of hard rubber. When the transducer box 10 is made of hard rubber, its strength is higher, and it is less prone to damage. In this case, the support portion 111 also has higher strength. When the button 50 is pressed and applies pressure to the support portion 111, the support portion 111 is less prone to deformation and damage, resulting in a longer service life for the transducer box 10. When the waterproof component is made of soft rubber, it is easier to deform, allowing the button 50 to easily trigger the switch 90 via the waterproof component 30. Users do not need to apply significant pressure to the button 50 to adjust the functions of the headphone 1000, resulting in a better user experience. The soft rubber can be, but is not limited to, rubber, silicone, thermoplastic elastomers, or polyvinyl chloride.

[0063] Please refer to Figures 3 to 5. In some embodiments, the waterproof component 30 includes a first waterproof part 31 and a second waterproof part 33. The first waterproof part 31 is located in the mounting hole 1111, and the second waterproof part 33 surrounds and is connected to the periphery of the first waterproof part 31. The second waterproof part 33 is embedded and connected to the support part 111 and is connected to the inner wall of the transducer box 10. When the button 50 applies force to the first waterproof part 31, the first waterproof part 31 deforms under force, and the second waterproof part 33 remains connected to the support part 111 and the inner wall of the transducer box 10.

[0064] The first waterproof part 31 is designed to deform when pressed by the button 50 (the pressure applied by the user to the button 50), so that the button 50 can trigger the switch 90 through the first waterproof part 31. The second waterproof part 33 is fixedly connected to both the receiving part and the inner wall of the transducer box 10. The second waterproof part 33 is designed to tighten the periphery of the waterproof component 30 by the transducer box 10, so as to prevent the waterproof component 30 from deforming under water pressure (the button 50 is subjected to water pressure and applies this pressure to the waterproof component 30) and accidentally triggering the switch 90.

[0065] Please refer to Figures 3 and 5. The second waterproof part 33 is embedded and connected to the support part 111 at a position close to the first waterproof part 31. At this time, part of the structure of the second waterproof part 33 can extend into the support part 111. The connection strength between the second waterproof part 33 and the support part 111 is high, and the support part 111 can tighten the second waterproof part 33, so that the waterproof component 30 is not easily deformed under small pressure. The position of the second waterproof part 33 away from the first waterproof part 31 (i.e., the periphery of the waterproof component 30) is connected to the inner wall of the transducer box 10, which can further improve the connection strength between the second waterproof part 33 and the transducer box 10. The transducer box 10 can tighten the periphery of the waterproof component 30, which can effectively prevent the waterproof component 30 from deforming under small pressure and accidentally triggering the switch 90. Furthermore, when the second waterproof part 33 is connected to the support part 111 and the inner wall of the transducer box 10, the second waterproof part 33 is not easily loosened relative to the transducer box 10 when the first waterproof part 31 is deformed by the pressure applied by the user, and the connection between the transducer box 10 and the waterproof part 30 is relatively stable. In addition, the waterproof part 30 has a good waterproof effect, and external liquids are not easily allowed to enter the mounting cavity 15 through the gap between the waterproof part 30 and the transducer box 10.

[0066] Please refer to Figure 3. Specifically, in some embodiments, the inner wall of the transducer box 10 is provided with a groove 13, at least a portion of the second waterproof part 33 is located in the groove 13, and the second waterproof part 33 forms a concave-convex fit with the inner wall of the transducer box 10.

[0067] The inner wall of the transducer box 10 has a protrusion surrounding the support portion 111. The periphery of the support portion 111 facing the mounting cavity 15 and the protrusion together form a groove 13. The position of the second waterproof portion 33 away from the first waterproof portion 31 (i.e., the periphery of the waterproof component 30) extends into the groove 13. At this time, the connection area between the second waterproof portion 33 and the inner wall of the transducer box 10 is large, the connection strength between the second waterproof portion 33 and the inner wall of the transducer box 10 is high, and the connection between the second waterproof portion 33 and the inner wall of the transducer box 10 is relatively tight. The inner wall of the transducer box 10 can tighten the periphery of the waterproof component 30, so that the first waterproof portion 31 is not easily deformed when the waterproof component 30 is subjected to water pressure, thereby effectively avoiding the problem of the waterproof component 30 accidentally touching the switch 90.

[0068] Please refer to Figures 3 to 5. In some embodiments, the support portion 111 includes a first protrusion 1113 and a second protrusion 1115. The first protrusion 1113 and the second protrusion 1115 are arranged in a stepped manner in the thickness direction Z of the button 50. The first protrusion 1113 is closer to the outside of the transducer box 10 than the second protrusion 1115.

[0069] Both the first protrusion 1113 and the second protrusion 1115 extend from the side wall of the box. The area of ​​the second protrusion 1115 is larger than that of the first protrusion 1113, and the second protrusion 1115 is closer to the center of the mounting hole 1111. At least a portion of the first waterproof part 31 is supported by the second protrusion 1115 and connected to the first protrusion 1113. The second waterproof part 33 is connected to the side of the second protrusion 1115 facing the mounting cavity 15. When the second protrusion 1115 and the first protrusion 1113 are arranged in a stepped manner, the contact area between the support part 111 and the waterproof component 30 is larger. After the support part 111 and the waterproof component 30 are integrally molded in two colors, the connection strength between the support part 111 and the waterproof component 30 is higher, and the waterproof component 30 is not easily loosened relative to the support part 111.

[0070] Please refer to Figures 4 and 5. In some embodiments, the second protrusion 1115 is provided with a through injection hole 11151, and at least a portion of the second waterproof part 33 is located in the injection hole 11151, so that the second waterproof part 33 is embedded and connected to the second protrusion 1115.

[0071] During the two-color injection molding process of the support portion 111 and the waterproof component 30, molten soft rubber flows into the injection hole 11151, and after solidification, the waterproof component 30 is formed. At this time, the second waterproof portion 33 of the waterproof component 30 can form a tight embedded connection with the support portion 111, and the support portion 111 can tighten the periphery of the waterproof component 30. The waterproof component 30 is not easily deformed under water pressure, and external liquid is not easily allowed to enter the mounting cavity 15 from the mounting hole 1111, resulting in a better waterproof effect for the transducer assembly 100. The number of injection holes 11151 can be, but is not limited to, one, two, three, four, or more. When there are multiple injection holes 11151, the connection strength between the second waterproof portion 33 and the support portion 111 is higher. In this application, there are four injection holes 11151, which are evenly distributed in the second waterproof portion 33.

[0072] Referring to Figures 3 and 5, in some embodiments, a protrusion 11131 is provided on the periphery of the first protrusion 1113 facing the second protrusion 1115, and a recess 311 is formed on the outer side of the first waterproof part 31, which mates with the protrusion 11131. In this case, the connection area between the first waterproof part 31 and the first protrusion 1113 is large, the connection strength between the first waterproof part 31 and the first protrusion 1113 is high, and the first protrusion 1113 can tighten the periphery of the first waterproof part 31. When the waterproof component 30 is subjected to water pressure, the first waterproof part 31 is less prone to deformation, thereby effectively preventing the problem of accidental activation of the switch 90 due to deformation of the waterproof component 30. The number of protrusions 11131 can be, but is not limited to, one, two, three, four, or more, and the number of recesses 311 is the same as the number of protrusions 11131. When there are multiple protrusions 11131, the connection strength between the first waterproof part 31 and the supporting part 111 is high; in this application, there are four protrusions 11131.

[0073] Please refer to Figures 5 and 6. In some embodiments, the support portion 111 is provided with a support portion 113 on the side facing the mounting cavity 15. The support portion 113 is arranged around the mounting hole 1111 and protrudes toward the mounting cavity 15 relative to the second protrusion 1115.

[0074] The support portion 113 is used to enhance the strength of the supporting portion 111. During the two-color injection molding process of the waterproof component 30 and the support portion 113, the support portion 113 provides good support for the supporting portion 111, effectively preventing deformation of the supporting portion 111 under pressure during processing, and making the supporting portion 111 less prone to damage. When the support portion 113 is located on the side of the supporting portion 111 facing the transducer box 10, the strength of the supporting portion 111 is enhanced without affecting the overall structure of the product. In addition, the support portion 113 can also be embedded and connected to the second waterproof portion 33. When the first waterproof portion 31 is subjected to water pressure, the support portion 113 can tighten and fix the second waterproof portion 33, thereby preventing deformation of the first waterproof portion 31 and the problem of accidental activation of the switch 90.

[0075] The number of support portions 113 can be, but is not limited to, one, two, three, four, or more. When there is only one support portion 113, the structure of the support portion 111 is relatively simple and easy to manufacture. When there are multiple support portions 113, the strength of the support portion 111 is higher, and the support portion 111 is less prone to deformation. In this case, the multiple support portions 113 can be evenly or non-uniformly distributed on the support portion 111. In this application, there are four support portions 113, and the four support portions 113 and the four injection holes 11151 are distributed alternately.

[0076] Please refer to Figures 3 to 5. In some embodiments, in the thickness direction Z of the waterproof component 30, the first waterproof part 31 includes a first side 313 and a second side 315 facing away from each other. The first side 313 of the first waterproof part is closer to the outside of the transducer box 10 than the second side. The first side 313 of the first waterproof part includes a mounting post 3131, which is provided with a insertion hole 3132. In the thickness direction Z of the waterproof component 30, the button 50 includes a first side 51 and a second side 53 facing away from each other. The first side 51 of the button is closer to the outside of the transducer box 10 than the second side 53. The second side 53 of the button is provided with a connecting post 531, which extends into the insertion hole 3132 of the mounting post 3131.

[0077] With the connecting post 531 inserted into the insertion hole 3132, the connection between the button 50 and the waterproof component 30 is relatively stable, and the button 50 is not easily loosened relative to the waterproof component 30. At least a portion of the connecting post 531 can correspond to the switch 90, so that when the button 50 is pressed, at least a portion of the connecting post 531 can cause the waterproof component 30 to deform. The at least a portion of the connecting post 531 can trigger the switch 90 through the waterproof component 30, thereby facilitating the adjustment of the headphone 1000's functions.

[0078] Please refer to Figure 3. In some embodiments, the second side 315 of the first waterproof part is provided with a trigger protrusion 3151. In the thickness direction Z of the waterproof part 30, the trigger protrusion 3151 corresponds to the switch 90 and is used to abut against the switch 90.

[0079] The trigger protrusion 3151 protrudes from the second side 315 of the first waterproof part toward the mounting cavity 15. When the user applies external force to the button 50, the button 50 causes the first waterproof part 31 to deform. At this time, the trigger protrusion 3151 can come into contact with the switch 90, thereby triggering the switch 90. With the trigger protrusion 3151 provided on the second side 315 of the first waterproof part, the waterproof component 30 can trigger the switch 90 more easily, the transducer assembly 100 has better sensitivity, and the user experience is better.

[0080] Please refer to Figures 4 and 5. In some embodiments, the center of the insertion hole 3132 is located on the length midline and width midline of the first waterproof part 31.

[0081] At this point, the insertion hole 3132 is centered on the waterproof component 30, and the connecting post 531 on the button 50 is also centered. When the button 50 is subjected to external force, the force is concentrated in the middle of the button 50, thus the deformation of the first waterproof part 31 is also concentrated in the middle. Therefore, on the one hand, the connecting post 531 on the button 50 can better trigger the switch 90 through the first waterproof part 31; on the other hand, the tensile force on the periphery of the waterproof component 30 (the second waterproof part 33) is more even, avoiding the problem that some parts experience greater tensile force than others, leading to easy damage to the second waterproof part 33. With even force distribution across all parts of the second waterproof part 33, the service life of the waterproof component 30 can be extended.

[0082] Referring to Figures 3 to 5, in some embodiments, there are multiple mounting posts 3131, each with multiple insertion holes 3132. There are also multiple connecting posts 531, each inserted into one of the multiple insertion holes 3132. In this case, multiple connection points are formed between the button 50 and the first waterproof part 31, resulting in a stronger connection between the button 50 and the waterproof part 30, better connection stability, and further prevention of the button 50 from becoming loose relative to the waterproof part 30.

[0083] Please refer to Figures 4 and 5. In some embodiments, multiple mounting posts 3131 are arranged sequentially along the length direction X or width direction Y of the waterproof component 30. Adjacent mounting posts 3131 share a sidewall, and at least one mounting post 3131 has a notch 3133 that penetrates the inner and outer sides and communicates with the insertion hole 3132.

[0084] When the connecting post 531 is inserted into the insertion hole 3132, the notch 3133 is used to allow the gas inside the insertion hole 3132 to be discharged so that the connecting post 531 can be inserted into the bottom of the insertion hole 3132. The connection stability between the connecting post 531 and the insertion hole 3132 is good, and the connection stability between the button 50 and the waterproof component 30 is also good.

[0085] Please refer to Figures 4 and 5. In some embodiments, each mounting post 3131 is provided with a notch 3133, and the extension direction of the plurality of notches 3133 is consistent with the length direction X or the width direction Y of the waterproof component 30.

[0086] In one embodiment, a plurality of mounting posts 3131 are arranged sequentially along the length X of the waterproof component 30, and a plurality of notches 3133 extend in the same direction as the length X of the waterproof component 30. In this case, the plurality of notches 3133 can communicate with each other, and can approximately form a straight line. During the insertion of the connecting post 531 into the insertion hole 3132, gas inside each insertion hole 3132 enters the notch 3133 formed by the mounting post 3131. The gas in the notch 3133 can flow through the other notches 3133 and eventually exit outside the waterproof component 30.

[0087] In another embodiment, a plurality of mounting posts 3131 are arranged sequentially along the width direction Y of the waterproof component 30, and a plurality of notches 3133 extend in the same direction as the width direction Y of the waterproof component 30. In this case, the plurality of notches 3133 can communicate with each other, and can approximately form a straight line. During the insertion of the connecting post 531 into the insertion hole 3132, gas inside each insertion hole 3132 enters the notch 3133 formed by the mounting post 3131. The gas in the notch 3133 can flow through the other notches 3133 and eventually exit outside the waterproof component 30.

[0088] Each mounting post 3131 is provided with a notch 3133. When the extension direction of multiple notches 3133 is consistent with the length direction X or width direction Y of the waterproof component 30, it is convenient for the gas in multiple insertion holes 3132 to be discharged to the outside of the waterproof component 30. As a result, the connection between the connecting post 531 and the insertion hole 3132 is more stable, and the connection strength between the button 50 and the waterproof component 30 is higher.

[0089] Referring to Figure 7, 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.

[0090] In the headphone system 10000 of this application embodiment, the waterproof component 30 is located in the mounting area 11 and integrally molded with the transducer box 10 using dual-color injection molding. The button 50 is mounted in the mounting area 11 and connected to the waterproof component 30. When a user wears the headphones 1000 while swimming or diving, and the button 50 is subjected to a certain water pressure, the button 50 will transmit this pressure to the waterproof component 30. Because the connection strength between the periphery of the waterproof component 30 and the transducer box 10 is high, the periphery of the waterproof component 30 can be tightened by the transducer box 10. The waterproof component 30 is not easily deformed when subjected to pressure applied by the button 50, so the button 50 will not trigger the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30. This application can effectively avoid the problem of accidental activation of the switch 90 on the circuit board 70 of the transducer assembly 100 under high water pressure, resulting in a better user experience.
