[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figures 1 to 8, the present utility model provides a waterproof earphone 100, which includes a housing 110, a control main board 120, a fixing member 130 and a waterproof membrane 140. The housing 110 is composed of an upper shell 111 and a lower shell 112. The upper shell 111 and the lower shell 112 are connected to each other to form a receiving space 113, and the receiving space 113 can be used to place the control main board 120. Among them, a through hole 114 is provided on the housing 110. The through hole 114 can be provided on the upper shell 111, or can be provided on the lower shell 112, or the housing 110 has a plurality of through holes 114, and some of the through holes 114 are provided on the upper shell 111 and some of the through holes 114 are provided on the lower shell 112. The through hole 114 is communicated with the receiving space 113 to facilitate sound transmission. The fixing member 130 is arranged in the receiving space 113 and can be fixed on the upper shell 111 or the lower shell 112. An audio channel 131 is provided on the fixing member 130. The audio channel 131 has a first opening 132 and a second opening 133, wherein the first opening 132 is communicated with the through hole 114, and the second opening 133 faces the control main board 120. The waterproof membrane 140 is located between the fixing member 130 and the control main board 120, and can cover and seal the second opening 133 to prevent water or other liquids from entering the control main board 120 and ensure the waterproof effect.

[0039] Specifically, the connection between the fixing member 130 and the upper shell 111 or the lower shell 112 ensures the stability of the entire earphone structure. The design of the audio channel 131 enables sound to enter through the first opening 132 and then be transmitted to the control main board 120 through the second opening 133, ensuring the effective transmission of audio signals. The setting of the waterproof membrane 140 not only plays a role in covering the second opening 133, but also ensures good sealing performance. The waterproof membrane 140 can be made of a material with good air permeability and waterproofness to ensure sound transmission while maintaining the waterproof effect, such as a TPU film (thermoplastic polyurethane film) or other polymer waterproof and breathable membranes. Thus, the waterproof membrane 140 can effectively prevent moisture from invading, protect the internal control main board 120 from damage, and ensure audio quality. In some embodiments, the waterproof membrane 140 can be designed as a multi-layer structure to further enhance the waterproof performance. The housing 110 can be made of a waterproof material or undergo waterproof treatment to enhance the overall waterproof performance.

[0040] It can be understood that, in some embodiments, the fixing member 130 can be designed to be detachable for easy maintenance or replacement. In some other embodiments, the fixing member 130 can also be integrally formed with the upper shell 111 or the lower shell 112. The waterproof earphone 100 of the present application includes, but is not limited to, Bluetooth wireless earphones, ear-hook Bluetooth earphones, bone conduction Bluetooth earphones, and ear-clamp Bluetooth earphones, etc. The waterproof earphone 100 is suitable for wearing during sports such as fitness, cycling, and running.

[0041] Please refer to Figure 2 andFigure 3 , in some embodiments, the control main board 120 includes an audio unit 121, and the waterproof membrane 140 includes a main body portion 141 and a sound transmission portion 142. The thickness of the sound transmission portion 142 is less than that of the main body portion 141. The sound transmission portion 142 faces the audio unit 121, and there is a certain gap between them. The thickness of the sound transmission portion 142 is designed to be thinner than that of the main body portion 141, reducing the loss of sound signals at the waterproof membrane 140, enabling the sound signals to be effectively conducted to the audio unit 121 or conducted from the audio unit 121 to the through hole 114. In the related art, in order to ensure the transmission of audio signals and reduce the impact of external environmental moisture or debris on the earphone, the size of the microphone hole is usually reduced to block most of the debris. Compared with the related art, the present application uses the waterproof membrane 140 to waterproof the earphone, reducing the design and manufacturing difficulty of the through hole 114. At the same time, the design of the sound transmission portion 142 of the waterproof membrane 140 ensures the acquisition and release of audio signals by the earphone, overcoming the problem that the audio signals are blocked by the waterproof structure arranged in the microphone hole in the related art, and improving the waterproof performance of the earphone. That is, the interval design between the sound transmission portion 142 and the audio unit 121 ensures that the sound signals can be transmitted without obstacles, while the main body portion 141 of the waterproof membrane 140 continues to perform the waterproof function.

[0042] Specifically, the selection of the material and thickness of the sound transmission portion 142 is based on the consideration of audio transmission characteristics. The material of the sound transmission portion 142 usually needs to have good sound penetration ability, while the main body portion 141 needs to have strong waterproof performance. By designing the sound transmission portion 142 to be thinner, the attenuation of audio signals can be reduced, maintaining good sound quality. In addition, maintaining a certain distance between the sound transmission portion 142 and the audio unit 121 can prevent the waterproof membrane 140 from vibrating under the action of sound signals and contacting the audio unit 121, causing interference or signal loss, further improving the quality of audio transmission. In addition, having a gap between the sound transmission portion 142 and the audio unit 121 can also provide sufficient vibration space for the waterproof membrane 140, preventing the sound transmission portion 142 of the waterproof membrane 140 from contacting or even rubbing against other structural components during frequent vibration, resulting in damage to the waterproof membrane 140 or other structural components, thereby increasing the service life of the waterproof membrane 140 and ensuring that the waterproof earphone 100 has a high service life.

[0043] In some embodiments, the control main board 120 has a perforation corresponding to the second opening 133, and the sound transmission part 142 is configured to be able to completely cover the perforation. It should be noted that the sound transmission part 142 and the control main board 120 can be in contact with each other, or the sound transmission part 142 and the control main board 120 can be spaced apart, that is, there is a gap between the sound transmission part 142 and the control main board. The setting of the perforation is conducive to the conduction of the audio signal from one side of the control main board 120 close to the fixing member 130 to the other side of the control main board 120 away from the fixing member 130, reducing the sound loss during the transmission of the audio signal, so that other components receiving the audio signal (including but not limited to the audio unit 121) can obtain sufficiently clear sound information, thereby improving the audio quality of the earphone.

[0044] Please refer to Figure 6 , in some embodiments, the audio channel 131 includes a first channel 1311 and a second channel 1312. One end of the first channel 1311 is connected to the through hole 114, the other end is connected to the second channel 1312, the other end of the second channel 1312 is connected to the second opening 133, and the orientation of the first channel 1311 is perpendicular to that of the second channel 1312. Such a design optimizes the transmission path of the audio signal, so that the audio signal entering from the outside can enter the internal accommodation space 113 along the first channel 1311 and then be transmitted to the audio unit 121 on the control main board 120 via the second channel 1312.

[0045] Specifically, the design of the audio channel 131 ensures that the audio signal can smoothly enter the control main board 120 through the vertically arranged first channel 1311 and second channel 1312. The design of the first channel 1311 perpendicular to the second channel 1312 enables the sound signal to change direction after entering the fixing member 130, avoiding directly entering the accommodation space 113 and reducing the possibility of water or other impurities entering the accommodation space 113. In addition, the first channel 1311 and the second channel 1312 are perpendicularly connected, which can reduce the noise interference caused by the linear arrangement of the channels, thereby improving the audio quality. In other words, through the design of the first channel 1311 and the second channel 1312 being perpendicularly connected, the direction of sound propagation is changed, effectively preventing external water vapor or impurities from directly entering the internal accommodation space 113, and improving the waterproof performance of the waterproof earphone 100. The vertically connected channel design optimizes the sound signal during transmission and ensures the clarity of the sound quality. It can be understood that in some embodiments, the connection between the first channel 1311 and the second channel 1312 can be designed with a smooth transition to reduce the reflection loss during sound transmission. The sizes of the first channel 1311 and the second channel 1312 can be adjusted according to actual needs to adapt to different earphone sizes and sound quality requirements. A filtering device such as a dust-proof net can be added at the connection between the first channel 1311 and the second channel 1312 to further prevent dust and other impurities from entering the accommodation space 113.

[0046] Please refer to Figure 5 and Figure 6 In some embodiments, the control main board 120 of the waterproof earphone 100 has a first surface 122 facing the second opening 133. The extending direction of the first channel 1311 in the fixing member 130 is parallel to the first surface 122, while the second channel 1312 is perpendicular to the first surface 122. Such a structural design is beneficial to optimizing the transmission efficiency of audio signals, ensuring that audio signals can be efficiently transmitted from the outside to the control main board 120. The setting of the first channel 1311 parallel to the first surface 122 enables the audio signal to flow smoothly along the first channel 1311 until it reaches the second channel 1312, and then is transmitted vertically downward to the control main board 120.

[0047] Specifically, the first surface 122 of the control main board 120 faces the second opening 133, which enables the audio signal to be directly transmitted to the audio unit 121 on the control main board 120. The design of the first channel 1311 parallel to the first surface 122 ensures that the transmission of the audio signal in the first channel 1311 is unobstructed, while the second channel 1312 perpendicular to the first surface 122 helps to directly guide the audio signal to the control main board 120, reducing the loss during the signal transmission process. The combination of the first channel 1311 parallel to the first surface 122 and the second channel 1312 perpendicular to the first surface 122 ensures the efficient transmission of sound signals, and effectively prevents external water vapor or impurities from entering the accommodation space 113. This design not only improves the waterproof performance of the waterproof earphone 100, but also ensures the clarity of the sound quality, thus ensuring the audio quality.

[0048] It can be understood that in some embodiments, the extending direction of the first channel 1311 can also have a certain inclination angle relative to the first surface 122 of the control main board 120 to optimize the transmission path of the sound signal. The transition between the first channel 1311 and the second channel 1312 can be designed to be smooth, that is, the connection between the first channel 1311 and the second channel 1312 can be designed to have a certain arc to reduce the reflection loss of the sound signal and improve the sound quality. In some embodiments, an acoustic treatment layer can be added to the surface of the audio channel 131 to further improve the transmission quality of the sound signal.

[0049] Please refer to Figure 6, in some embodiments, a limiting groove 134 is further provided on the fixing member 130. The limiting groove 134 communicates with the second opening 133 and is capable of accommodating the waterproof film 140. Specifically, the design of the limiting groove 134 on the fixing member 130 can ensure that the waterproof film 140 is correctly installed and held in place so that the waterproof film 140 can effectively seal the second opening 133, thereby preventing water from entering the accommodating space 113. It should be noted that, to further improve the installation stability of the waterproof film 140, an adhesive layer can be provided between the waterproof film 140 and the fixing member 130, that is, the waterproof film 140 can be adhered to the limiting groove 134 by means of back glue. After the housing 110 and the control main board 120 are installed in place, the limiting groove 134 and the control main board 120 jointly define the installation position of the waterproof film 140 and enable it to stably cover the second opening 133. The existence of the limiting groove 134 not only helps to fix the position of the waterproof film 140 but also further enhances the waterproof function. Through the cooperation of the limiting groove 134 and the second opening 133, the waterproof film 140 can be stably installed, preventing the waterproof film 140 from shifting during the assembly process or use, and also preventing the waterproof film 140 from shifting due to movement or other external forces, ensuring the waterproof effect.

[0050] It can be understood that, in some embodiments, the limiting groove 134 can be designed to have a certain depth to ensure that the waterproof film 140 will not easily fall off after assembly. The edge of the limiting groove 134 can be designed with a smooth transition to avoid damaging the waterproof film 140. It can be understood that, in some embodiments, the shape of the limiting groove 134 can be customized according to the specific size of the waterproof film 140 to ensure that the waterproof film 140 can be precisely embedded in the limiting groove 134. The limiting groove 134 can be designed with a buckle or an adhesive layer to further enhance the fixing effect of the waterproof film 140.

[0051] Please refer to Figure 6 , in some embodiments, the waterproof earphone 100 further includes a seal 150. The seal 150 has an avoidance hole 151 which is connected to the through hole 114. The seal 150 is located between the waterproof film 140 and the control main board 120 and has elasticity. At least a part of the seal 150 protrudes from the limiting groove 134 and blocks part of the limiting groove 134 to block part of the waterproof film 140. Through the elastic design of the seal 150, it can play a buffering role when the earphone is subjected to external force impact, and at the same time ensure the close contact between the waterproof film 140 and the control main board 120, enhancing the waterproof effect.

[0052] Specifically, the seal 150 communicates with the through hole 114 through the avoidance hole 151, enabling sound to pass through normally. In addition, the seal 150 is elastic, enabling it to closely adhere between the waterproof film 140 and the control main board 120 to form a sealing effect. A part of the seal 150 protrudes from the limit groove 134 and blocks part of the waterproof film 140. After the housing 110, the fixing member 130, and the control main board 120 are installed in place, the seal 150 is in a contracted state under the extrusion of the fixing member 130 and the control main board 120, causing the seal 150 to be in close contact with the fixing member 130, effectively preventing water vapor from flowing out through the gap between the fixing member 130 and the waterproof film 140 and contaminating other structural components. In addition, the seal 150 can also provide a continuous force to the waterproof film 140, enabling the waterproof film 140 to be tightly connected to the fixing member 130, further enhancing the fixing effect of the waterproof film 140. In addition, the elastic design of the seal 150 enables it to adapt to different assembly tolerances, ensuring the consistency of the sealing effect. The elastic design of the seal 150 is also beneficial for preventing the fixing member 130 from causing wear to the control main board 120, effectively protecting the control main board 120.

[0053] It can be understood that in some embodiments, the seal 150 can be made of a highly elastic material, such as silicone or rubber, to ensure good sealing performance. The protruding part of the seal 150 can be designed to have a certain thickness to ensure that it can effectively block the waterproof film 140. It can be understood that in some embodiments, the seal 150 can be designed with a corrugated or raised structure to increase the contact area with the waterproof film 140 and the control main board 120, further improving the sealing effect. The seal 150 can be coated with an adhesive on the side in contact with the waterproof film 140 to enhance the fixing effect. In some embodiments, the seal 150 can exist both between the fixing member 130 and the control main board 120 and between the waterproof film 140 and the control main board 120, thereby improving the sealing effect.

[0054] Please refer to Figure 2 and Figure 3, in some embodiments, the fixing member 130 and the housing 110 are made of different materials, and the fixing member 130 is detachably assembled to the housing 110. The fixing member 130 is made of an elastic material. When the upper housing 111 is assembled to the lower housing 112, one end of the fixing member 130 abuts against the upper housing 111, and the other end abuts against the control main board 120 and / or the waterproof film 140, and the fixing member 130 is in a compressed state. The fixing member 130 is made of an elastic material so that the fixing member 130 has a certain elasticity to ensure the tightness and waterproof performance of the earphone during the assembly process. During the assembly process, the elastic characteristic of the fixing member 130 enables it to closely adhere to the upper housing 111 and at the same time tightly press the control main board 120 and the waterproof film 140, which can ensure the stability of the fixing member 130 inside the earphone and further guarantee the effective sealing of the waterproof film 140.

[0055] Specifically, through the elastic design of the fixing member 130, a pre-tightening force can be generated when the upper housing 111 and the lower housing 112 are assembled, ensuring the stability of the control main board 120 and the waterproof film 140 in the accommodation space 113. The elastic characteristic of the fixing member 130 also helps to absorb external vibrations, protect the control main board 120 and the waterproof film 140 from the influence of external impacts, and improve the durability and reliability of the waterproof earphone 100. It can be understood that in some embodiments, the fixing member 130 can be made of highly elastic materials such as silica gel and rubber to ensure good elasticity and durability. In some embodiments, the elastic material of the fixing member 130 can also have certain waterproof characteristics, further improving the overall waterproof performance of the waterproof earphone 100.

[0056] Please refer to Figure 7 and Figure 8 , in some embodiments, the control main board 120 includes an indicator light 123 and a Bluetooth module, and the Bluetooth module can establish or disconnect a connection with an external device. The indicator light 123 displays different lighting states according to the connection state between the Bluetooth module and the external device. The fixing member 130 also has a limiting hole 135, and the indicator light 123 can pass through the limiting hole 135 and face the through hole 114 so that the lighting state of the indicator light 123 can be displayed through the through hole 114. The design of the indicator light 123 enables the user to intuitively understand the current connection state of the Bluetooth module. Since the position of the indicator light 123 is designed at the limiting hole 135 of the fixing member 130 and the light can be displayed through the through hole 114, the user can intuitively understand the connection state between the Bluetooth module and the external device, improving the user's convenience of use and the user experience.

[0057] The design of the limiting hole 135 ensures the fixed position of the indicator light 123, avoiding the displacement or loosening of the indicator light 123 during use and ensuring the stability of the lighting effect of the indicator light 123. It can be understood that in some embodiments, the color of the indicator light 123 can change according to different states of the Bluetooth module, such as showing green when the connection is successful and showing red when not connected. The brightness of the indicator light 123 can be adjusted to adapt to different usage environments. In some embodiments, the indicator light 123 can also be configured to have multiple lighting modes, such as flashing, constant on, etc., to provide more diverse status prompts. The shape of the limiting hole 135 can be customized according to the specific size of the indicator light 123 to ensure that the indicator light 123 can be precisely embedded and fixed.

[0058] It should be noted that the through hole 114 can be used to implement functions such as calls, voice control, and noise cancellation of the earphone, which can improve the sound quality of the earphone and promote the development of the earphone towards AI intelligence. In some embodiments, the through hole 114 is used to implement the call function of the earphone. The control main board 120 includes a speaker, and the through hole 114 design of the upper shell 111 or the lower shell 112 can guide the sound emitted by the speaker out of the accommodation space 113. Among them, the speaker is installed on the control main board 120, and the sound information emitted by the speaker can be conducted through the second opening 133 of the audio channel 131 to the audio channel 131. The first opening 132 of the fixing member 130 communicates with the external environment through the through hole 114, so as to allow the sound to be transmitted to the outside of the earphone through the through hole 114. Through the design of the through hole 114, the sound of the speaker can be smoothly transmitted out, ensuring the clarity of the sound quality. The through hole 114 is combined with sealing measures such as the waterproof film 140 to ensure that the waterproof earphone 100 can also work normally in a humid or underwater environment, improving the waterproof performance of the earphone. It can be understood that in some embodiments, the power and frequency response of the speaker can be optimized according to actual needs to meet the usage requirements in different scenarios. A waterproof ring or other sealing materials can be provided around the through hole 114 to further enhance the waterproof effect.

[0059] In some embodiments, the through-hole 114 is used to implement the noise reduction function of the earphone. The control main board 120 includes a noise reducer. The design of the through-hole 114 in the upper shell 111 or the lower shell 112 can direct the external audio information to the noise reducer. Specifically, the noise reducer is installed on the control main board 120. The sound of the external environment can be transmitted to the noise reducer through the through-hole 114. After the noise reducer collects the external sound, these noises are eliminated or weakened through a processing algorithm, thereby improving the noise reduction effect of the earphone. Through the design of the through-hole 114, the noise reducer can effectively capture the external environmental noise, providing the necessary audio information for noise reduction processing. The operation of the noise reducer cooperates with sealing measures such as the waterproof film 140 to ensure that the waterproof earphone 100 can maintain a good noise reduction effect while being waterproof. It can be understood that in some embodiments, the noise reducer can integrate multiple noise reduction modes, such as active noise reduction and passive noise reduction, to adapt to different usage scenarios. A windproof cover or other auxiliary structures can be provided around the through-hole 114 to reduce the influence of wind noise and enhance the user's auditory experience.
