Transduction assembly, earphone and earphone system

Abstract

The utility model discloses a transduction assembly, an earphone and an earphone system. The transduction assembly comprises a transduction box, a deformable waterproof piece and a key. And a mounting area is arranged on the transduction box. The waterproof part is located in the installation area and integrally formed with the transduction box in a double-shot molding mode. The waterproof part is used for covering an opening, facing the interior of the transduction box, of the installation area. The key is installed in the installation area and connected with the waterproof piece, and the key is exposed out of the transduction box from the installation area. When a user wears the earphone to swim or dive and the button is subjected to a certain water pressure, the button transmits the pressure to the waterproof member. As the connection strength between the periphery of the waterproof part and the transduction box is high, the periphery of the waterproof part can be tensioned by the transduction box, and the waterproof part is not easy to deform under the pressure applied by the key, so that the key does not trigger a switch on the circuit board of the transduction assembly through the waterproof part. The problem that the switch on the circuit board of the transduction assembly is mistakenly touched under the condition that the water pressure is large can be effectively avoided, and the use experience feeling of a user is good.

Description

Technical Field

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

[0002] The transducer assembly of the earphones is used to enable the user to hear sounds. A deformable waterproof part is usually provided between the transducer box and the button of the transducer assembly. On the one hand, the waterproof part can prevent external liquid from entering the transducer box. On the other hand, when the user presses the button, the waterproof part can be deformed to trigger the switch on the circuit board inside the transducer box, thereby realizing functions such as answering a call or adjusting the volume of the earphones. However, when the user is swimming or diving, due to excessive water pressure, the button will be subjected to pressure exerted by the water flow. The button transfers the pressure to the waterproof part, which will undergo a certain deformation and trigger the switch on the circuit board. There is a risk of the switch on the circuit board being accidentally touched, affecting the actual use of the earphones. Utility Model Content

DETAILED DESCRIPTION

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] The transducer assembly of the earphone is used to enable the user to hear sounds. A deformable waterproof part is usually provided between the transducer box and the button of the transducer assembly. On the one hand, the waterproof part can prevent external liquid from entering the transducer box. On the other hand, when the user presses the button, the waterproof part can be deformed to trigger the switch on the circuit board inside the transducer box, thereby realizing functions such as answering a call or adjusting the volume of the earphone. However, when the user is swimming or diving, due to excessive water pressure, the button will be subjected to pressure exerted by the water flow, and the button will transfer the pressure to the waterproof part. The waterproof part will undergo a certain deformation and trigger the switch on the circuit board. There is a risk of the switch on the circuit board being accidentally touched, affecting the actual use of the earphone. In order to solve this problem, the embodiment of the present application provides a transducer assembly 100( Figure 2 As shown), earphones 1000 ( Figure 1 shown) and earphone system 10000 ( Figure 7 shown).

[0044] See also Figure 1 and Figure 2 The earphone 1000 of the embodiment of the present application includes a transducer assembly 100. In some embodiments, the earphone 1000 includes a bone conduction earphone 1000 and an air conduction earphone 1000.

[0045] 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.

[0046] The transducer assembly 100 of the present application is used to fit against human skin. When the earphone 1000 is in use, the transducer assembly 100 can generate vibrations, which are conducted through the human body's bones, thereby enabling the user to hear sounds. The earphone 1000 of the present application also includes a function box assembly 300, which is electrically connected to the transducer assembly 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 and off of the earphone 1000 and adjust the volume of the earphone 1000. The battery box assembly 303 includes a battery, which is used to power other components of the earphone 1000 so that the earphone 1000 can operate normally.

[0047] See also 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 to electrically connect the battery box assembly 303 and the transducer assembly 100, and to electrically connect the control box assembly 301 and the transducer assembly 100. The back hook 700 is used to electrically connect 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 wearing stability of the earphone 1000 and preventing the earphone 1000 from falling off when the user is outdoors or exercising.

[0048] See also Figures 2 to 4 The transducer assembly 100 of the embodiment of the present application includes a transducer box 10, a deformable waterproof member 30, and a button 50. The transducer box 10 is provided with a mounting area 11. The waterproof member 30 is located in the mounting area 11 and is integrally molded with the transducer box 10 by two-color injection molding. The waterproof member 30 is used to cover the opening of the mounting area 11 facing the interior of the transducer box 10. The button 50 is installed in the mounting area 11 and connected to the waterproof member 30. The button 50 is exposed from the mounting area 11 to the outside of the transducer box 10.

[0049] See also Figure 2 Specifically, the transducer box 10 may be provided with a mounting cavity 15 for mounting other components of the transducer assembly 100. For example, the vibrating component and microphone of the transducer assembly 100 may be mounted in the mounting cavity 15. The mounting area 11 is for mounting the waterproof member 30 and the button 50.

[0050] See also Figures 2 to 4The button 50 is installed in the installation area 11 and is at least partially exposed from the installation area 11 to facilitate the user to operate the button 50. For example, the user can control the power on and off of the headset 1000 through the button 50, the user can also adjust the volume of the headset 1000 through the button 50, and the user can also operate the button 50 to answer calls, play music, pause music, and switch songs. The button 50 is connected to the waterproof component 30. When the button 50 is pressed, the button 50 can cause the waterproof component 30 to deform. When the waterproof component 30 is deformed to contact the switch 90 on the circuit board 70 of the transducer component 100, the switch 90 on the circuit board 70 of the transducer component 100 can be triggered, so that the function of the headset 1000 can be adjusted.

[0051] See also Figure 2 In some embodiments, the button 50 and the mounting area 11 are clearance-fitted, that is, a gap may exist between the button 50 and the sidewall of the mounting area 11. Even if external liquid enters between the button 50 and the sidewall of the mounting area 11 and between the button 50 and the waterproof member 30, since the waterproof member 30 and the transducer box 10 are integrally molded by two-color injection molding, the external liquid will not pass through the waterproof member 30 and enter the mounting cavity 15. During movement or swinging of the earphone 1000, the liquid between the button 50 and the waterproof member 30 may flow out of the transducer assembly 100 through the gap. The gap between the button 50 and the sidewall of the mounting area 11 facilitates the drainage of liquid from the mounting area 11.

[0052] See also Figures 3 to 5 The waterproof part 30 is used to prevent external liquid from entering the installation cavity 15 from the installation area 11, so as to prevent the external liquid from affecting the normal operation of the components in the installation cavity 15. The waterproof part 30 is connected to the side wall of the installation area 11. The material of the waterproof part 30 of the present application is different from that of the transducer box 10. In the case of two-color injection molding between the waterproof part 30 and the transducer box 10, the connection between the waterproof part 30 and the transducer box 10 is relatively tight, which can effectively prevent external liquid from entering the installation cavity 15 through the gap between the waterproof part 30 and the transducer box 10. The transducer assembly 100 has a good waterproof effect. In addition, the connection strength between the periphery of the waterproof part 30 and the transducer box 10 is relatively high. The periphery of the waterproof part 30 can be tightened by the transducer box 10. When the waterproof part 30 is subjected to a small external force, the waterproof part 30 is not easy to deform.

[0053] For example, the earphones 1000 of the present application may be swimming earphones 1000. When a user wears the earphones 1000 while swimming or diving, the button 50 is subjected to a certain amount of water pressure, which is transmitted to the waterproof member 30 (usually, this pressure is less than the pressure applied by the user). Since the periphery of the waterproof member 30 is tightened by the transducer box 10, the waterproof member 30 hardly deforms when subjected to this pressure. This prevents the button 50 from triggering the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof member 30. This effectively avoids the risk of accidental touch of the switch 90 on the circuit board 70 of the transducer assembly 100, providing a better user experience. When the user needs to adjust the function of the earphone 1000 through the button 50, the user can apply greater pressure on the button 50. At this time, the button 50 transmits the pressure to the waterproof part 30. When the waterproof part 30 is subjected to the pressure, it can be deformed to contact the switch 90 on the circuit board 70 of the transducer component 100, so that the button 50 can trigger the switch 90 on the circuit board 70 of the transducer component 100 through the waterproof part 30 to adjust the function of the earphone 100.

[0054] In the transducer assembly 100 of the embodiment of the present application, the waterproof component 30 is located in the installation area 11 and is integrally formed with the transducer box 10 by double-color injection molding. The button 50 is installed in the installation area 11 and is connected to the waterproof component 30. When the user wears the earphones 1000 to swim or dive, and the button 50 is subjected to a certain water pressure, the button 50 will transmit the pressure to the waterproof component 30. Since the connection strength between the periphery of the waterproof component 30 and the transducer box 10 is relatively high, the periphery of the waterproof component 30 can be tightened by the transducer box 10, and the waterproof component 30 is not easily deformed when subjected to the pressure applied by the button 50, so that the button 50 will not trigger the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30. The present application can effectively avoid the problem of the switch 90 on the circuit board 70 of the transducer assembly 100 being accidentally touched when the water pressure is relatively high, and the user experience is better.

[0055] The energy conversion assembly 100 will be further described below with reference to the accompanying drawings.

[0056] See also Figures 3 to 5 In some embodiments, the mounting area 11 is provided with a supporting portion 111 , which extends from the side wall of the transducer box 10 and forms a mounting hole 1111 , and the waterproof member 30 and the supporting portion 111 are integrally formed by two-color injection molding.

[0057] The supporting portion 111 is used to support the waterproof component 30 and the button 50. When the waterproof component 30 and the supporting portion 111 are integrally formed by two-color injection molding, the connection between the waterproof component 30 and the supporting portion 111 is relatively tight, and external liquid is not easy to enter the transducer box 10 from the mounting hole 1111. The connection strength between the periphery of the waterproof component 30 and the supporting portion 111 is relatively high, and the periphery of the waterproof component 30 can be tightened by the supporting portion 111. When the user wears the headphones 1000 to swim or dive, the waterproof component 30 can be prevented from being deformed by the pressure of the button 50 and accidentally touching the switch 90 on the circuit board 70 of the transducer assembly 100.

[0058] See also Figure 3 and Figure 5 In some embodiments, the transducer assembly 100 further includes a circuit board 70 and a switch 90 housed in the transducer box 10. The switch 90 is mounted on the circuit board 70 and corresponds to the waterproof component 30. When the button 50 is pressurized and causes the waterproof component 30 to deform, the waterproof component 30 contacts the switch 90, causing the switch 90 to be triggered.

[0059] Mounting hole 1111 communicates with mounting cavity 15 and is configured to allow switch 90 to be exposed therethrough. Switch 90 corresponds to waterproof member 30. When a user wishes to adjust a function of earphone 1000, they press button 50, which transmits pressure to waterproof member 30. This pressure causes waterproof member 30 to deform toward the inside of transducer box 10. This deformation can contact switch 90, thereby triggering switch 90 on circuit board 70.

[0060] See also Figures 3 to 5 In some embodiments, the hardness of the waterproof part 30 is less than the hardness of the transducer box 10. In this case, the waterproof part 30 can be easily deformed when subjected to external force. When the user presses the button 50, the button 50 can apply pressure to the waterproof part 30, so that the waterproof part 30 can be deformed to trigger the switch 90. The user does not need to apply a large force to the button 50 to trigger the switch 90, the sensitivity of the transducer component 100 is better, and the user experience is better. In the case that the hardness of the waterproof part 30 is greater than the hardness of the function box, when the user triggers the button 50, the button 50 applies pressure to the waterproof part 30, and the waterproof part 30 is not easy to deform, so that the waterproof part 30 is difficult to contact the switch 90, the adjustment of the transducer component 100 is not sensitive enough, and the user experience is poor.

[0061] See also Figures 3 to 5In some embodiments, the waterproof component 30 is made of soft glue and the transducer box 10 is made of hard glue. When the transducer box 10 is made of hard glue, the strength of the transducer box 10 is relatively high, and the transducer box 10 is not easily damaged. At this time, the strength of the supporting portion 111 is also relatively high. When the button 50 is pressed and the button 50 applies a certain pressure to the supporting portion 111, the supporting portion 111 is not easily deformed or damaged, and the service life of the transducer box 10 is relatively long. When the waterproof glue is made of soft glue, the soft glue can be easily deformed, thereby facilitating the button 50 to trigger the switch 90 through the waterproof component 30. The user does not need to apply a large pressure on the button 50 to adjust the function of the earphone 1000, and the user experience is better. Among them, the soft glue can be, but is not limited to, rubber, silicone, thermoplastic elastomer or polyvinyl chloride.

[0062] See also Figures 3 to 5 In some embodiments, the waterproof component 30 includes a first waterproof portion 31 and a second waterproof portion 33. The first waterproof portion 31 is located in the mounting hole 1111, and the second waterproof portion 33 surrounds and is connected to the periphery of the first waterproof portion 31. The second waterproof portion 33 is embedded in the supporting portion 111 and is connected to the inner wall of the transducer box 10. When the button 50 applies force to the first waterproof portion 31, the first waterproof portion 31 is deformed by the force, and the second waterproof portion 33 remains connected to the supporting portion 111 and the inner wall of the transducer box 10.

[0063] The first waterproof portion 31 is configured to deform when subjected to a pressing force applied by the button 50 (the user's pressing force on the button 50), so that the button 50 can trigger the switch 90 through the first waterproof portion 31. The second waterproof portion 33 is fixedly connected to both the supporting portion and the inner sidewall of the transducer box 10. The second waterproof portion 33 is configured to tighten the periphery of the waterproof member 30 by the transducer box 10 to prevent the waterproof member 30 from deforming and accidentally triggering the switch 90 when subjected to water pressure (the button 50 is subjected to water pressure and applies this pressure to the waterproof member 30).

[0064] See also Figure 3 and Figure 5The second waterproof portion 33 is connected to the supporting portion 111 at a position close to the first waterproof portion 31. At this time, part of the second waterproof portion 33 can extend into the supporting portion 111. The connection strength between the second waterproof portion 33 and the supporting portion 111 is relatively high, and the supporting portion 111 can pull the second waterproof portion 33 tight, so that the waterproof member 30 is not easily deformed when subjected to a small pressure. The second waterproof portion 33 is connected to the inner side wall of the transducer box 10 at a position away from the first waterproof portion 31 (i.e., the periphery of the waterproof member 30), thereby further improving the connection strength between the second waterproof portion 33 and the transducer box 10. The transducer box 10 can pull the periphery of the waterproof member 30 tight, effectively preventing the waterproof member 30 from deforming under a small pressure and causing the switch 90 to be accidentally touched. Furthermore, when the second waterproof portion 33 is connected to the support portion 111 and the inner sidewall of the transducer box 10, even when the first waterproof portion 31 is deformed by pressure applied by a user, the second waterproof portion 33 is unlikely to become loose relative to the transducer box 10, and the connection between the transducer box 10 and the waterproof member 30 is relatively stable. Furthermore, the waterproof member 30 provides a good waterproof effect, and external liquid is unlikely to enter the mounting cavity 15 through the gap between the waterproof member 30 and the transducer box 10.

[0065] See also Figure 3 Specifically, in some embodiments, the inner wall of the transducer box 10 is provided with a groove 13, at least part of the second waterproof portion 33 is located in the groove 13, and the second waterproof portion 33 forms a concave-convex fit with the inner wall of the transducer box 10.

[0066] The inner side wall of the transducer box 10 is provided with a protrusion surrounding the supporting portion 111. The peripheral edge of the supporting 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 peripheral edge of the waterproof member 30) extends into the groove 13. At this time, the connection area between the second waterproof portion 33 and the inner side wall of the transducer box 10 is large, the connection strength between the second waterproof portion 33 and the inner side wall of the transducer box 10 is high, and the connection between the second waterproof portion 33 and the inner side wall of the transducer box 10 is relatively tight. The inner side wall of the transducer box 10 can tighten the peripheral edge of the waterproof member 30. Therefore, when the waterproof member 30 is subjected to water pressure, the first waterproof portion 31 is not easily deformed, thereby effectively avoiding the problem of the waterproof member 30 accidentally touching the switch 90.

[0067] See also Figures 3 to 5 In some embodiments, the supporting 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 key 50. The first protrusion 1113 is closer to the outside of the transducer box 10 than the second protrusion 1115.

[0068] Both the first protrusion 1113 and the second protrusion 1115 extend from the sidewall of the box body. The area of ​​the second protrusion 1115 is larger than that of the first protrusion 1113 and is closer to the center of the mounting hole 1111. At least a portion of the first waterproof portion 31 is supported by the second protrusion 1115 and connected to the first protrusion 1113. The second waterproof portion 33 is connected to the side of the second protrusion 1115 facing the mounting cavity 15. The stepped arrangement of the second protrusion 1115 and the first protrusion 1113 increases the contact area between the support portion 111 and the waterproof member 30. After the support portion 111 and the waterproof member 30 are integrally molded by two-color injection molding, the connection strength between the support portion 111 and the waterproof member 30 is high, making it difficult for the waterproof member 30 to loosen relative to the support portion 111.

[0069] See also Figure 4 and Figure 5 In some embodiments, the second protrusion 1115 is provided with an injection hole 11151 therethrough, and at least a portion of the second waterproof portion 33 is located in the injection hole 11151 , so that the second waterproof portion 33 is embedded and connected to the second protrusion 1115 .

[0070] During the process of double-color injection molding of the supporting portion 111 and the waterproof component 30, the molten soft glue flows into the injection hole 11151, and the molten soft glue solidifies to form the waterproof component 30. At this time, the second waterproof portion 33 of the waterproof component 30 can form a tight embedded connection with the supporting portion 111, and the supporting portion 111 can tighten the periphery of the waterproof component 30. The waterproof component 30 is not easy to deform under water pressure, and external liquid is not easy to enter the installation cavity 15 from the installation hole 1111, and the transducer assembly 100 has a better waterproof effect. The number of injection holes 11151 can be, but is not limited to, one, two, three, four or more. When the number of injection holes 11151 is multiple, the connection strength between the second waterproof portion 33 and the supporting portion 111 is higher. The number of injection holes 11151 in this application is four, and the four injection holes 11151 are evenly distributed on the second waterproof portion 33.

[0071] See also Figure 3 and Figure 5In some embodiments, a protrusion 11131 is provided on the periphery of the first protrusion 1113 facing the second protrusion 1115. A recess 311 is formed on the outer side of the first waterproof portion 31, which engages with the protrusion 11131. In this manner, the connection area between the first waterproof portion 31 and the first protrusion 1113 is large, the connection strength between the first waterproof portion 31 and the first protrusion 1113 is high, and the first protrusion 1113 can tighten the periphery of the first waterproof portion 31. When the waterproof member 30 is subjected to water pressure, the first waterproof portion 31 is less likely to deform, thereby effectively preventing the problem of accidental activation of the switch 90 due to deformation of the waterproof member 30. The number of protrusions 11131 can be, but is not limited to, one, two, three, four, or more. The number of recesses 311 and the number of protrusions 11131 are the same. When there are multiple protrusions 11131, the connection strength between the first waterproof portion 31 and the supporting portion 111 is higher. In the present application, there are four protrusions 11131.

[0072] See also Figure 5 and Figure 6 In some embodiments, a support portion 113 is provided on the side of the supporting portion 111 facing the inside of the transducer box 10 . The support portion 113 is arranged around the mounting hole 1111 and protrudes toward the inside of the transducer box 10 relative to the second protrusion 1115 .

[0073] The support portion 113 is used to improve the strength of the supporting portion 111. During the process of double-color injection molding of the waterproof part 30 and the support portion 113, the support portion 113 can play a good supporting role for the supporting portion 111, which can effectively avoid the problem of the supporting portion 111 being deformed due to pressure during the processing, and the supporting portion 111 is not easily damaged. In the case where the support portion 113 is arranged on the side of the supporting portion 111 facing the inside of the transducer box 10, the strength of the supporting portion 111 can be improved without affecting the overall structure of the product. In addition, the support portion 113 can also be embedded in 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 avoiding the problem of the first waterproof portion 31 being deformed and accidentally touching the switch 90.

[0074] The number of support parts 113 can be, but is not limited to, one, two, three, four or more. When there is one support part 113, the structure of the supporting part 111 is relatively simple and the processing is relatively simple. When there are multiple support parts 113, the strength of the supporting part 111 is higher and the supporting part 111 is not easily deformed. In this case, the multiple support parts 113 can be evenly or unevenly distributed on the supporting part 111. The number of support parts 113 in the present application is four, and the four support parts 113 and the four injection holes 11151 are distributed at intervals from each other.

[0075] See also Figures 3 to 5In some embodiments, in the thickness direction Z of the waterproof member 30, the first waterproof portion 31 includes a first side 313 and a second side 315 opposite to each other, the first side 313 of the first waterproof portion is closer to the outside of the transducer box 10 than the second side, the first side 313 of the first waterproof portion includes a mounting post 3131, and the mounting post 3131 is provided with a plug hole 3132; in the thickness direction Z of the waterproof member 30, the button 50 includes a first side 51 and a second side 53 opposite to 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, and the connecting post 531 extends into the plug hole 3132 of the mounting post 3131.

[0076] When the connecting post 531 is inserted into the insertion hole 3132, the connection between the button 50 and the waterproof member 30 is relatively stable, and the button 50 is unlikely to become loose relative to the waterproof member 30. At least a portion of the connecting post 531 may correspond to the switch 90, so that when the button 50 is pressed, at least a portion of the connecting post 531 may cause the waterproof member 30 to deform. At least a portion of the connecting post 531 may trigger the switch 90 through the waterproof member 30, thereby facilitating adjustment of the functions of the earphone 1000.

[0077] See also Figure 3 In some embodiments, the second side 315 of the first waterproof portion is provided with a trigger protrusion 3151 . In the thickness direction Z of the waterproof member 30 , the trigger protrusion 3151 corresponds to the switch 90 , and the trigger protrusion 3151 is used to interfere with the switch 90 .

[0078] A trigger protrusion 3151 protrudes from the second side 315 of the first waterproof portion toward the mounting cavity 15. When a user applies external force to the button 50, the button 50 causes the first waterproof portion 31 to deform, causing the trigger protrusion 3151 to contact the switch 90, thereby triggering the switch 90. With the trigger protrusion 3151 on the second side 3155 of the first waterproof portion, the waterproof member 30 can more easily trigger the switch 90, improving the sensitivity of the transducer assembly 100 and providing a better user experience.

[0079] See also Figure 4 and Figure 5 In some embodiments, the center of the plug hole 3132 is located on the length mid-plane and the width mid-plane of the first waterproof portion 31.

[0080] In this case, the insertion hole 3132 is centered on the waterproof member 30, and the connecting post 531 on the button 50 is also centered. When the button 50 is subjected to external force, the external force is more concentrated in the middle of the button 50, and the deformation of the first waterproof portion 31 is also more concentrated in the middle. As a result, on the one hand, the connecting post 531 on the button 50 can better trigger the switch 90 through the first waterproof portion 31. On the other hand, the pulling force on the periphery of the waterproof member 30 (the second waterproof portion 33) is also more uniform, which can prevent the problem of some parts being subjected to greater pulling force than others, which can easily damage the second waterproof portion 33. When the force is evenly applied to all parts of the second waterproof portion 33, the service life of the waterproof member 30 can be extended.

[0081] See also Figures 3 to 5 In some embodiments, multiple mounting posts 3131 are provided, each of which has multiple insertion holes 3132. Multiple connecting posts 531 are provided, each of which is inserted into each of the insertion holes 3132. This creates multiple connections between the button 50 and the first waterproof portion 31, thereby increasing the strength and stability of the connection between the button 50 and the waterproof member 30 and preventing the button 50 from becoming loose relative to the waterproof member 30.

[0082] See also Figure 4 and Figure 5 In some embodiments, multiple mounting columns 3131 are arranged in sequence along the length direction X or the width direction Y of the waterproof component 30, adjacent mounting columns 3131 share a side wall, and the side wall of at least one mounting column 3131 is provided with a notch 3133 that penetrates the inner and outer sides and connects to the plug hole 3132.

[0083] When the connecting column 531 is plugged into the plug hole 3132, the notch 3133 is used to allow the gas inside the plug hole 3132 to be discharged so that the connecting column 531 can be inserted into the bottom of the plug hole 3132. The connection stability between the connecting column 531 and the plug hole 3132 is better, and the connection stability between the button 50 and the waterproof part 30 is better.

[0084] See also Figure 4 and Figure 5 In some embodiments, each mounting column 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 .

[0085] In one embodiment, multiple mounting posts 3131 are arranged sequentially along the longitudinal direction X of the waterproof member 30, and the multiple notches 3133 extend in the same direction as the longitudinal direction X of the waterproof member 30. In this case, the multiple notches 3133 are interconnected, and the multiple notches 3133 can generally form a straight line. During the insertion of the connecting post 531 into the insertion hole 3132, the gas inside each insertion hole 3132 enters the notch 3133 formed by the mounting post 3131. The gas in the notch 3133 can then flow through the other notches 3133 and ultimately be discharged outside the waterproof member 30.

[0086] In another embodiment, multiple mounting posts 3131 are arranged sequentially along the width direction Y of the waterproof member 30, and the multiple notches 3133 extend in the same direction as the width direction Y of the waterproof member 30. In this case, the multiple notches 3133 can be interconnected, and the multiple notches 3133 can generally form a straight line. During the insertion of the connecting post 531 into the insertion hole 3132, the gas inside each insertion hole 3132 enters the notch 3133 formed by the mounting post 3131. The gas in the notch 3133 can then flow through the other notches 3133 and ultimately be discharged outside the waterproof member 30.

[0087] A notch 3133 is provided on each mounting column 3131. When 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, the gas in the plurality of plug holes 3132 can be discharged to the outside of the waterproof component 30, so that the connection between the connecting column 531 and the plug hole 3132 is more stable, and the connection strength between the button 50 and the waterproof component 30 is higher.

[0088] See also Figure 7 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.

[0089] In the earphone system 10000 of the embodiment of the present application, the waterproof component 30 is located in the installation area 11 and is integrally formed with the transducer box 10 by double-color injection molding. The button 50 is installed in the installation area 11 and is connected to the waterproof component 30. When the user wears the earphones 1000 to swim or dive, and the button 50 is subjected to a certain water pressure, the button 50 will transmit the pressure to the waterproof component 30. Since the connection strength between the periphery of the waterproof component 30 and the transducer box 10 is relatively high, the periphery of the waterproof component 30 can be tightened by the transducer box 10, and the waterproof component 30 is not easily deformed when subjected to the pressure applied by the button 50, so that the button 50 will not trigger the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof component 30. The present application can effectively avoid the problem of the switch 90 on the circuit board 70 of the transducer assembly 100 being accidentally touched when the water pressure is relatively high, and the user experience is better.
