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 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. The button transfers the pressure to the waterproof part, which will be deformed to a certain extent 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. Summary of the invention

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0043] The transducer assembly of the earphone is used to enable the user to hear sounds. A deformable waterproof component is usually provided between the transducer box and the button of the transducer assembly. On the one hand, the waterproof component can prevent external liquid from entering the transducer box. On the other hand, when the user presses the button, the waterproof component 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. The button transfers the pressure to the waterproof component, which will be deformed to a certain extent and trigger the switch on the circuit board. There is a risk of accidental touching of the switch on the circuit board, 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), earphone 1000( Figure 1 ) 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] Among them, the bone conduction earphone 1000 uses the human skeleton as a medium, and the bone conduction earphone 1000 converts sound into mechanical vibration, which transmits sound waves through the human skeleton so that the user can hear the sound. The sound of the bone conduction earphone 1000 acts on the skeleton, and long-term use will not cause a great impact on the eardrum of the user's ear, which can effectively protect the user's hearing. The air conduction earphone 1000 transmits sound through air vibration, and the air conduction earphone 1000 has good sound quality and penetration. The earphone 1000 of the present application is described by taking the bone conduction earphone 1000 as an example.

[0046] The transducer assembly 100 of the present application is used to fit with human skin. When the earphone 1000 is used, the transducer assembly 100 can generate vibrations, which are conducted through the bones of the human body, so that the user can hear the sound. 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 work 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 the user wears the earphone 1000, the back hook 700 of the earphone 1000 is worn on the head, and the ear hook 500 of the earphone 1000 is worn behind the ear, thereby improving the wearing stability of the earphone 1000, and the earphone 1000 is not easy to fall 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 an installation cavity 15, and the transducer box 10 is provided with an installation area 11 connected to the installation cavity 10. The waterproof member 30 is located in the installation area 11 and is integrally formed with the transducer box 10 by double-color injection molding. The waterproof member 30 is used to cover the opening of the installation area 11 toward the inside of the transducer box 10. The button 50 is installed in the installation area 11 and connected to the waterproof member 30. The button 50 is exposed from the installation area 11 to the outside of the transducer box 10.

[0049] See also Figure 2 Specifically, the installation cavity 15 is used for installing other components of the transducer assembly 100 therein, for example, the vibration component and microphone and other structures of the transducer assembly 100 can be installed in the installation cavity 15. The installation area 11 is used for installing the waterproof member 30 and the button 50 therein.

[0050] See also Figures 2 to 4The button 50 is installed in the installation area 11 and at least partially exposed from the installation area 11, so that the user can 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 answer calls, play music, pause music, and switch songs by operating the button 50. The button 50 is connected to the waterproof member 30. When the button 50 is pressed, the button 50 can cause the waterproof member 30 to deform. When the waterproof member 30 is deformed to contact 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 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-matched, that is, there may be a gap between the button 50 and the side wall of the mounting area 11. In the case where external liquid enters between the button 50 and the waterproof member 30 from between the button 50 and the side wall of the mounting area 11, since the waterproof member 30 and the transducer box 10 are integrally formed by two-color injection molding, the external liquid will not enter the mounting cavity 15 through the waterproof member 30. During the 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 from the gap, and the gap between the button 50 and the side wall of the mounting area 11 may facilitate the discharge of the liquid in 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 peripheral edge of the waterproof part 30 and the transducer box 10 have a high connection strength. The peripheral edge 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 in the direction of the installation cavity 15.

[0053] For example, the earphone 1000 of the present application may be a swimming earphone 1000. When the user wears the earphone 1000 for swimming or diving, the button 50 is subjected to a certain water pressure, and the button 50 transmits the pressure to the waterproof part 30 (usually the pressure is less than the pressure pressed by the user). Since the periphery of the waterproof part 30 is tightened by the transducer box 10, the waterproof part 30 will hardly deform when subjected to the pressure, thereby preventing the button 50 from triggering the switch 90 on the circuit board 70 of the transducer assembly 100 through the waterproof part 30. The switch 90 on the circuit board 70 of the transducer assembly 100 can effectively avoid the risk of being accidentally touched, and the user's use experience is better. When the user needs to adjust the function of the earphone 1000 through the button 50, the user can apply a large pressure on the button 50. At this time, the button 50 transfers the pressure to the waterproof component 30. When the waterproof component 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 component 30 to adjust the function of the earphone 100.

[0054] In the transducer assembly 100 of the embodiment of the present application, the waterproof part 30 is located in the installation area 11 and is integrally formed with the transducer box 10 by double-color injection molding, and the button 50 is installed in the installation area 11 and connected to the waterproof part 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 part 30. Since 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, and the waterproof part 30 is not easy to deform 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 part 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's use experience is better.

[0055] The energy conversion assembly 100 is further described below in conjunction with the accompanying drawings.

[0056] See also Figures 3 to 5 In some embodiments, the mounting area 11 is provided with a supporting portion 111 , the supporting portion 111 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. In addition, 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 earphones 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 also includes a circuit board 70 and a switch 90 accommodated in the mounting cavity 15. The switch 90 is installed on the circuit board 70 and corresponds to the waterproof component 30. When the button 50 is pressed and the waterproof component 30 is deformed, the waterproof component 30 conflicts with the switch 90, so that the switch 90 is triggered.

[0059] The mounting hole 1111 is connected to the mounting cavity 15, and the mounting hole 1111 is used for the switch 90 to be exposed from the mounting hole 1111, and the switch 90 corresponds to the waterproof member 30. When the user needs to adjust the function of the earphone 1000, the user presses the button 50, and the button 50 transmits the pressure to the waterproof member 30, and the waterproof member 30 can be deformed toward the inside of the transducer box 10, and when the waterproof member 30 is deformed, it can contact with the switch 90, so as to trigger the switch 90 on the 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. At this time, it is convenient for the waterproof part 30 to deform 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's experience is better. In the case where 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's experience is poor.

[0061] See also Figures 3 to 5In some embodiments, the waterproof component 30 is a soft glue, and the transducer box 10 is a hard glue. When the transducer box 10 is a 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 a soft glue, the soft glue can be easily deformed, so that the button 50 can trigger the switch 90 through the waterproof component 30. The user does not need to apply a large pressure to the button 50 to adjust the function of the headset 1000, and the user has a better user experience. 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 used to deform when subjected to the pressing force applied by the button 50 (the pressing force applied by the user to 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 the bearing and release portion and the inner side wall of the transducer box 10, and the second waterproof portion 33 is used to tighten the periphery of the waterproof member 30 by the transducer box 10, so as to avoid the waterproof member 30 from deforming and accidentally touching the switch 90 when subjected to water pressure (the button 50 is subjected to water pressure and the pressure is applied to the waterproof member 30).

[0064] See also Figure 3 and Figure 5The position of the second waterproof part 33 close to the first waterproof part 31 is embedded and connected with the supporting part 111. At this time, part of the structure of the second waterproof part 33 can extend into the supporting part 111. The connection strength between the second waterproof part 33 and the supporting part 111 is relatively high. The supporting part 111 can tighten the second waterproof part 33, so that the waterproof part 30 is not easily deformed when subjected to a small pressure. The position of the second waterproof part 33 away from the first waterproof part 31 (that is, the periphery of the waterproof part 30) is connected to the inner side wall of the transducer box 10, so that the connection strength between the second waterproof part 33 and the transducer box 10 can be further improved. The transducer box 10 can tighten the periphery of the waterproof part 30, which can effectively avoid the problem of the waterproof part 30 deforming when subjected to a small pressure and accidentally touching the switch 90. Furthermore, when the second waterproof portion 33 is connected to the supporting portion 111 and the inner side wall of the transducer box 10, when the first waterproof portion 31 is deformed by the pressing force applied by the user, the second waterproof portion 33 is not easy to be loosened relative to the transducer box 10, and the connection between the transducer box 10 and the waterproof member 30 is relatively stable. In addition, the waterproof member 30 has a good waterproof effect, and external liquid is not easy to enter the installation 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 wall of the transducer box 10 is provided with a protrusion surrounding the supporting portion 111, and the peripheral edge of the supporting portion 111 facing the side of the installation cavity 15 and the protrusion together form a groove 13, and the position of the second waterproof portion 33 away from the first waterproof portion 31 (that is, 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 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 peripheral edge of the waterproof member 30, so that when the waterproof member 30 is subjected to water pressure, the first waterproof portion 31 is not easy to deform, 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] The first protrusion 1113 and the second protrusion 1115 both extend from the side wall of the box body, the area of ​​the second protrusion 1115 is larger than the area of ​​the first protrusion 1113, and the second protrusion 1115 is closer to the center of the mounting hole 1111. At least part of the first waterproof portion 31 is supported by the second protrusion 1115 and connected to the first protrusion 1113, and the second waterproof portion 33 is connected to the side of the second protrusion 1115 facing the mounting cavity 15. In the case where the second protrusion 1115 and the first protrusion 1113 are arranged in a stepped manner, the contact area between the supporting portion 111 and the waterproof member 30 is large, and after the supporting portion 111 and the waterproof member 30 are integrally formed by two-color injection molding, the connection strength between the supporting portion 111 and the waterproof member 30 is high, and the waterproof member 30 is not easy to loosen relative to the supporting portion 111.

[0069] See also Figure 4 and Figure 5 In some embodiments, the second protrusion 1115 is provided with an injection hole 11151 extending 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 two-color injection molding of the supporting part 111 and the waterproof part 30, the molten soft glue flows into the injection hole 11151, and the molten soft glue solidifies to form the waterproof part 30. At this time, the second waterproof part 33 of the waterproof part 30 can form a tight embedded connection with the supporting part 111, and the supporting part 111 can tighten the periphery of the waterproof part 30. The waterproof part 30 is not easy to deform under water pressure, and the external liquid is not easy to enter the installation cavity 15 from the installation hole 1111, and the transducer component 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 part 33 and the supporting part 111 is relatively high. There are four injection holes 11151 in the present application, and the four injection holes 11151 are evenly distributed in the second waterproof part 33.

[0071] See also Figure 3 and Figure 5In some embodiments, a convex block 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, and the recess 311 cooperates with the convex block 11131. At this time, 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 part 30 is subjected to water pressure, the first waterproof part 31 is not easy to deform, thereby effectively avoiding the problem of the waterproof part 30 deforming and accidentally touching the switch 90. The number of the convex blocks 11131 can be, but is not limited to, one, two, three, four or more, and the number of the recess 311 is the same as the number of the convex blocks 11131. When the number of the convex blocks 11131 is multiple, the connection strength between the first waterproof part 31 and the supporting part 111 is high, and the number of the convex blocks 11131 of the present application is four.

[0072] See also Figure 5 and Figure 6 In some embodiments, a supporting portion 113 is provided on one side of the supporting portion 111 facing the mounting cavity 15 . The supporting portion 113 is arranged around the mounting hole 1111 and protrudes toward the mounting cavity 15 relative to the second protrusion 1115 .

[0073] The support portion 113 is used to improve the strength of the supporting portion 111. In the process of two-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 deformation of the supporting portion 111 due to pressure during processing, and the supporting portion 111 is not easy to be 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 and connected with 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 deformation of the first waterproof portion 31 to accidentally touch the switch 90.

[0074] The number of the support parts 113 may 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 relatively high and the supporting part 111 is not easily deformed. At this time, the multiple support parts 113 may be evenly or unevenly distributed on the supporting part 111. The support parts 113 of the present application are 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, and the first side 313 of the first waterproof portion includes a mounting column 3131, and the mounting column 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, and the second side 53 of the button is provided with a connecting column 531, and the connecting column 531 extends into the plug hole 3132 of the mounting column 3131.

[0076] When the connecting column 531 is inserted into the plug hole 3132, the connection between the button 50 and the waterproof member 30 is relatively stable, and the button 50 is not easy to be loosened relative to the waterproof member 30. At least a portion of the connecting column 531 can correspond to the switch 90, so that when the button 50 is pressed, at least a portion of the connecting column 531 can drive the waterproof member 30 to deform, and at least a portion of the connecting column 531 can trigger the switch 90 through the waterproof member 30, so that the function of the earphone 1000 can be adjusted easily.

[0077] See also Figure 3 In some embodiments, a trigger protrusion 3151 is provided on the second side 315 of the first waterproof portion. 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 contact the switch 90 .

[0078] 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, and at this time, the trigger protrusion 3151 can contact the switch 90, thereby triggering the switch 90. When the second side 315 of the first waterproof part is provided with the trigger protrusion 3151, the waterproof part 30 can trigger the switch 90 more easily, the sensitivity of the transducer assembly 100 is better, and the user's use experience is better.

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

[0080] At this time, the plug hole 3132 is centered on the waterproof part 30, and the connecting column 531 on the button 50 can also be centered. When the button 50 is subjected to external force, the external force is more concentrated in the middle part of the button 50, so that the deformation of the first waterproof part 31 is also more concentrated in the middle part. Therefore, on the one hand, the connecting column 531 on the button 50 can better trigger the switch 90 through the first waterproof part 31, and on the other hand, the pulling force on the periphery of the waterproof part 30 (the second waterproof part 33) is also more uniform, which can avoid the problem that the pulling force on some parts is greater than that on other parts, resulting in the second waterproof part 33 being easily damaged. When the forces are evenly applied to each part of the second waterproof part 33, the service life of the waterproof part 30 can be extended.

[0081] See also Figures 3 to 5 In some embodiments, the mounting posts 3131 include a plurality of mounting posts 3131, and the plurality of mounting posts 3131 are provided with a plurality of plug holes 3132. The connecting posts 531 include a plurality of connecting posts 531, and the plurality of connecting posts 531 are respectively plugged into the plurality of plug holes 3132. At this time, a plurality of connections are formed between the button 50 and the first waterproof portion 31, so that the connection strength between the button 50 and the waterproof member 30 is higher, the connection stability between the button 50 and the waterproof member 30 is better, and the problem of the button 50 being loose relative to the waterproof member 30 can be further avoided.

[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 member 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 is connected 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 component 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, a plurality of mounting posts 3131 are sequentially arranged along the length direction X of the waterproof member 30, and the extension direction of the plurality of notches 3133 is the same as the length direction X of the waterproof member 30. At this time, the plurality of notches 3133 can be interconnected, and the plurality of notches 3133 can roughly form a straight line. During the process of plugging the connecting post 531 into the plug hole 3132, the gas inside each plug hole 3132 enters the notch 3133 formed by the mounting post 3131, and the gas in the notch 3133 can flow through the other plurality of notches 3133 and finally be discharged to the outside of the waterproof member 30.

[0086] In another embodiment, a plurality of mounting posts 3131 are sequentially arranged along the width direction Y of the waterproof member 30, and the extension direction of the plurality of notches 3133 is the same as the width direction Y of the waterproof member 30. In this case, the plurality of notches 3133 may be interconnected, and the plurality of notches 3133 may roughly form a straight line. During the process of plugging the connecting post 531 into the plug hole 3132, the gas inside each plug hole 3132 enters the notch 3133 formed by the mounting post 3131, and the gas in the notch 3133 may flow through the other plurality of notches 3133, and finally be discharged to the outside of 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, and the charging box 3000 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 box.

[0089] In the earphone system 10000 of the embodiment of the present application, the waterproof part 30 is located in the installation area 11 and is integrally formed with the transducer box 10 by double-color injection molding, and the button 50 is installed in the installation area 11 and connected to the waterproof part 30. When the user wears the earphone 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 part 30. Since 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, and the waterproof part 30 is not easy to deform 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 part 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's use experience is better.
