Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, the meaning of "plurality" is two or more, unless otherwise clearly specified.

[0050] In the embodiments of the present application, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0051] The microphone is usually fixed directly in the existing traditional earphones. The sealing effect of the microphone is poor and it is prone to air leakage, which leads to a decrease in call quality and affects the user experience.

[0052] To solve the above technical problems, refer to Figures 1-6 As shown, an embodiment of the present application provides an earphone, comprising: a housing 1, a first accommodation chamber 2, a first sound transmission component 3, and a first sealing member (not shown in the figure). The housing 1 is provided with a first sound inlet 4; the first accommodation chamber 2 is provided within the housing 1 and communicates with the first sound inlet 4, and a first mounting opening 5 is provided on one side of the first accommodation chamber 2; the first sound transmission component 3 includes a first microphone 6 and a first conductive member 7, the first microphone 6 being provided within the first accommodation chamber 2, the first conductive member 7 being electrically connected to the first microphone 6 and extending outside the first mounting opening 5; and a first sealing member being provided at the first mounting opening 5.

[0053] In this embodiment of the present application, the specific type of the earphones in the embodiment of the present application is not particularly limited, and may be, for example, open-ear headphones, sports headphones, etc. Specifically:

[0054] The housing 1, serving as the basic structure of the entire earphone, not only protects the internal components but also defines a first sound inlet 4 for external sound to enter the earphone, ensuring that the sound is effectively transmitted to the first microphone 6. It will be appreciated that in this example, the specific location of the first sound inlet 4 is not particularly limited, as long as it can serve the purpose of sound intake.

[0055] The first chamber 2 is located within the housing 1 and is used to accommodate the first microphone 6. This chamber is connected to the first sound inlet 4, ensuring that external sound can enter the first chamber 2 through the first sound inlet 4 and be transmitted to the first microphone 6 inside, improving the efficiency and quality of sound collection.

[0056] In the first sound transmission component 3, the first microphone 6 is responsible for converting the sound signal into an electrical signal, and the first conductive member 7 is responsible for transmitting these electrical signals to the main circuit board 31 inside the earphone to realize the processing and output of the sound signal.

[0057] The first seal is installed at the first installation port 5. Its function is to seal the area where the first microphone 6 is located to prevent air from entering from the outside or leaking out from the inside, thereby reducing the interference of environmental noise and maintaining the pressure balance around the first microphone 6, which helps to improve call clarity.

[0058] When a user wears the headset for a call, external sound is transmitted through the first sound inlet 4 to the first microphone 6 in the first accommodation chamber 2. The first microphone 6 captures the sound and converts it into electrical signals. These electrical signals are transmitted to the main circuit board 31 inside the headset via the first conductive member 7. After processing, they are then transmitted by the headset or used for local playback.

[0059] The presence of the first seal effectively isolates the first microphone 6, reduces unnecessary sound leakage, ensures that the first microphone 6 can capture the desired sound more accurately, and reduces the influence of background noise.

[0060] Therefore, the embodiment of the present application can prevent microphone leakage by optimizing the installation method and sealing of the microphone inside the headset, significantly improve call quality, and provide users with a clearer and more stable call environment.

[0061] According to one embodiment of the present application, referring to Figure 3 、 Figure 5-Figure 8 As shown, the first sound transmission component 3 further includes a first microphone sleeve 8, which is sleeved on the first microphone 6 and clamped in the first accommodation chamber 2, and the first microphone sleeve 8 is provided with a first through hole 9 connected to the first sound inlet 4.

[0062] In this embodiment of the present application, the first microphone sleeve 8 can firmly install the first microphone 6 in the first receiving chamber 2, ensuring that the position of the first microphone 6 is stable and not easily shifted due to external factors (such as strenuous exercise), which is conducive to improving call quality.

[0063] Furthermore, the first microphone housing 8 is provided with a first through hole 9 that communicates with the first sound inlet 4, ensuring that sound can be smoothly transmitted from the outside to the first microphone 6. This design has the advantage of maintaining an unobstructed sound transmission path without significant attenuation or distortion, ensuring accurate sound collection, and also protecting the first microphone 6 from physical damage.

[0064] In addition, the first microphone cover 8 can be made of a material with a certain degree of elasticity, which can absorb and buffer external vibrations, thereby reducing the impact of these vibrations on sound collection. This is particularly important for improving call quality, especially when using the headset in a noisy or dynamic environment.

[0065] Therefore, by adding the first microphone sleeve 8, the embodiment of the present application can further enhance the stability and vibration resistance of the first microphone 6, thereby improving the quality of sound collection. This design is very helpful in improving the user's call experience, especially in application scenarios that require high-quality audio communication, such as online conferencing, distance learning, or professional recording.

[0066] According to one embodiment of the present application, referring to Figure 7 and Figure 8 As shown, the first microphone sleeve 8 is provided with a first accommodating groove 10 adapted to the first microphone 6 , the first accommodating groove 10 is communicated with the first through hole 9 , and the first microphone 6 is embedded in the first accommodating groove 10 .

[0067] In this embodiment of the present application, the first accommodating groove 10 is a groove provided inside the first microphone housing 8, and its shape and size match the first microphone 6. The design of the first accommodating groove 10 allows the first microphone 6 to be precisely embedded therein, ensuring that its position is fixed and prevented from loosening or shifting, further enhancing the stability and reliability of the first microphone 6.

[0068] Furthermore, the first accommodating groove 10 is connected to the first through hole 9, ensuring that sound can be smoothly transmitted from the first sound inlet 4 through the first through hole 9 to the first microphone 6 in the first accommodating groove 10, thereby improving the accuracy and clarity of sound collection.

[0069] According to one embodiment of the present application, the first microphone sleeve 8 is a flexible member, and the first microphone sleeve 8 and the first accommodating chamber 2 are interference fit.

[0070] In this embodiment of the present application, the first microphone cover 8 is made of a flexible material with a certain elasticity and deformation ability. This material selection can better adapt to the shape of the first microphone 6 and ensure that it can fit tightly during installation.

[0071] Furthermore, the first microphone sleeve 8 is designed to have an interference fit with the first accommodating chamber 2, meaning that the first microphone sleeve 8 is slightly larger than the first accommodating chamber 2. Specifically, when the first sound transmission assembly 3 is snapped into the first accommodating chamber 2, its overall height is greater than or equal to the height of the first accommodating chamber 2, with the height difference within the range of 0-0.5 mm. This means that the first microphone sleeve 8 is slightly compressed and deformed during installation, adapting to the shape of the first accommodating chamber 2 and generating a certain extrusion preload. This preload ensures that the first microphone sleeve 8 and the first microphone 6 remain fixed within the first accommodating chamber 2 and will not loosen due to external vibration or movement, further enhancing the stability and reliability of the installation and effectively reducing the impact of external vibration on sound collection.

[0072] Therefore, the embodiment of the present application not only solves the problem of air leakage of the first microphone 6, but also optimizes the installation and sound collection performance of the first microphone 6, and significantly improves the user's call experience.

[0073] According to one embodiment of the present application, referring to Figure 5 The first sound collecting assembly 3 further comprises a first tuning net 11, which is arranged at the first through hole 9 of the first microphone sleeve 8.

[0074] Specifically, the first tuning net 11 can be arranged between the first microphone 6 and the first through hole 9 of the first microphone sleeve 8, which can effectively block water droplets and dust from entering the first microphone 6. This not only protects the first microphone 6 from physical damage, but also reduces the decline in sound quality caused by dust or moisture.

[0075] In addition, the first tuning net 11 can be made of a material with good air permeability, ensuring that sound can pass smoothly without affecting the transmission quality of sound.

[0076] According to one embodiment of the present application, referring to Figure 2 and Figure 6 The shell 1 comprises a first peripheral wall 12 and a first end face 13 connected to each other, the first peripheral wall 12 has a first side 14, the first sound inlet hole 4 is arranged at the bottom of the first peripheral wall 12 adjacent to the first side 14, and the first accommodating chamber 2 is arranged at the inner wall of the first end face 13 adjacent to the first sound inlet hole 4.

[0077] Specifically, the first sound inlet hole 4 is arranged at the bottom of the first peripheral wall 12 adjacent to the first side 14, and the first side 14 is the inner side close to the user's mouth. This design allows the first microphone 6 to capture the user's sound signal more directly and clearly, reducing the interference of background noise. In addition, the position design of the first sound inlet hole 4 also helps to reduce the direct wind flow, further reduces the wind noise, and improves the call quality.

[0078] According to one embodiment of the present application, referring to Figure 2 , Figure 4-Figure 6 The side of the first end face 13 away from the first sound inlet hole 4 is provided with a second sound inlet hole 15, the inner wall of the first end face 13 adjacent to the second sound inlet hole 15 is provided with a second accommodating chamber 16, the second accommodating chamber 16 is in communication with the second sound inlet hole 15, and one side of the second accommodating chamber 16 is provided with a second mounting opening 17.

[0079] The earphone further comprises a second sound collecting assembly 18 and a second sealing member (not shown in the figure), the second sound collecting assembly 18 comprises a second microphone 19 and a second conductive member 20, the second microphone 19 is arranged in the second accommodating chamber 16, and the second conductive member 20 is electrically connected with the second microphone 19 and extends out of the second mounting opening 17; the second sealing member is arranged at the second mounting opening 17.

[0080] In this embodiment of the present application, the second accommodating chamber 16 is located in the shell 1 and is a space for accommodating the second microphone 19. The space is in communication with the second sound inlet hole 15, ensuring that external sound can enter the second accommodating chamber 16 through the second sound inlet hole 15 and be transmitted to the internal second microphone 19, improving the efficiency and quality of sound collection.

[0081] In the second sound collection assembly 18, the second microphone 19 is responsible for converting sound signals into electrical signals, and the second conductive member 20 is responsible for transmitting the electrical signals to the main circuit board 31 inside the earphone to realize the processing and output of sound signals.

[0082] The second sealing member is installed at the second mounting port 17 and is used to seal the area where the second microphone 19 is located, avoiding air from entering from the outside or leaking from the inside, thereby reducing the interference of environmental noise and maintaining the pressure balance around the second microphone 19, which helps to improve the clarity of the call.

[0083] When the user wears the earphone to make a call, the sound from the outside is transmitted to the second microphone 19 in the second accommodating chamber 16 through the second sound inlet hole 15. After the second microphone 19 captures the sound, it converts it into an electrical signal. These electrical signals are transmitted to the main circuit board 31 inside the earphone through the second conductive member 20, and after processing, they are sent out by the earphone or used for local playback.

[0084] The presence of the second sealing member effectively isolates the second microphone 19, reduces unnecessary sound leakage, ensures that the second microphone 19 can more accurately capture the required sound, and reduces the influence of background noise.

[0085] Therefore, the embodiment of the present application can prevent the microphone from leaking air and significantly improve the call quality by optimizing the installation method and sealing performance of the microphone inside the earphone, providing a clearer and more stable call environment for the user. In addition, the double-microphone design further improves the call quality by obtaining sound from different positions, especially when used in noisy environments, which can significantly improve the call experience.

[0086] According to one embodiment of the present application, as shown in Figure 4-Figure 6 , Figure 9 and Figure 10 , the second sound collection assembly 18 further comprises a second microphone sleeve 21, which is sleeved on the second microphone 19 and is clamped in the second accommodating chamber 16, and the second microphone sleeve 21 is provided with a second through hole 22 in communication with the second sound inlet hole 15.

[0087] In this embodiment of the present application, the second microphone sleeve 21 can firmly install the second microphone 19 in the second accommodating chamber 16, ensuring the stability of the position of the second microphone 19, and preventing the second microphone 19 from being displaced due to external factors (such as violent movement), thereby improving the call quality.

[0088] In addition, the second microphone sleeve 21 is provided with a second through hole 22 that is in communication with the second sound inlet hole 15, so that sound can be smoothly transmitted from the outside to the second microphone 19. The advantage of this design is that the sound transmission path is kept unobstructed, without obvious attenuation or distortion, ensuring the accuracy of sound collection and protecting the second microphone 19 from physical damage.

[0089] In addition, the second microphone sleeve 21 can be made of a material with a certain elasticity, which can absorb and buffer external vibrations, thereby reducing the impact of these vibrations on sound collection. This is particularly important for improving call quality, especially when using the earphone in a noisy or dynamic environment.

[0090] Therefore, by adding the second microphone sleeve 21, the stability and vibration resistance of the second microphone 19 can be further enhanced, and the quality of sound collection is improved.

[0091] According to one embodiment of the present application, referring to FIGS. 1 to 3, Figure 9 and Figure 10 the second microphone sleeve 21 is provided with a second accommodating groove 23 that is adapted to the second microphone 19, the second accommodating groove 23 is in communication with the second through hole 22, and the second microphone 19 is embedded in the second accommodating groove 23.

[0092] In this embodiment of the present application, the second accommodating groove 23 is a groove arranged inside the second microphone sleeve 21, and the shape and size of the second accommodating groove 23 are matched with the second microphone 19. The design of the second accommodating groove 23 allows the second microphone 19 to be accurately embedded therein, ensuring that the position of the second microphone 19 is fixed and cannot be loosened or displaced, thereby further enhancing the stability and reliability of the second microphone 19.

[0093] In addition, the second accommodating groove 23 is in communication with the second through hole 22, ensuring that sound can be smoothly transmitted from the second sound inlet hole 15 to the second microphone 19 in the second accommodating groove 23 through the second through hole 22, thereby improving the accuracy and clarity of sound collection.

[0094] According to one embodiment of the present application, the second microphone sleeve 21 is a flexible member, and the second microphone sleeve 21 is in interference fit with the second accommodating chamber 16.

[0095] In this embodiment of the present application, the second microphone sleeve 21 is made of a flexible material and has a certain elasticity and deformation ability. The selection of this material can better adapt to the shape of the second microphone 19, ensuring that it can be closely fitted during installation.

[0096] And, the second microphone sleeve 21 is designed to be in interference fit with the second accommodating chamber 16, that is, the size of the second microphone sleeve 21 is slightly larger than the size of the second accommodating chamber 16. Specifically, when the second sound receiving assembly 18 is clamped into the second accommodating chamber 16, the overall height thereof is greater than or equal to the height of the second accommodating chamber 16, and the height difference is within the range of 0-0.5 mm. This means that the second microphone sleeve 21 will be slightly compressed and deformed when installed, adapt to the shape of the second accommodating chamber 16, and generate a certain extrusion pre-tightening force. This pre-tightening force can ensure that the second microphone sleeve 21 and the second microphone 19 are fixed in the second accommodating chamber 16 and will not loosen due to external vibration or movement, further enhancing the stability and reliability of the installation and effectively reducing the influence of external vibration on sound collection.

[0097] Therefore, the embodiments of the present application not only solve the air leakage problem of the second microphone 19, but also further optimize the installation and sound collection performance of the second microphone 19, and significantly improve the user's call experience.

[0098] According to an embodiment of the present application, referring to Figure 5 the second sound receiving assembly 18 further comprises a second tuning mesh 24, which is arranged at the second through hole 22 of the second microphone sleeve 21.

[0099] Specifically, the second tuning mesh 24 can be arranged in the second accommodating chamber 16 and located between the second sound inlet hole 15 and the second through hole 22 of the second microphone sleeve 21, which can effectively block water droplets and dust from entering the second microphone 19. This not only protects the second microphone 19 from physical damage, but also reduces the decline in sound quality caused by dust or moisture.

[0100] And, the second tuning mesh 24 can be made of a material with good air permeability to ensure that sound can pass smoothly without affecting the transmission quality of the sound.

[0101] According to an embodiment of the present application, the first and second sealing members can be sealing glue.

[0102] Specifically, the first and second sealing members are sealing glue, which seals the installation opening of the corresponding accommodating chamber after the installation of the corresponding sound receiving assembly is completed, achieving efficient sealing. The use of sealing glue ensures the air tightness of the area where the microphone is located, prevents air leakage, and improves the call quality. Moreover, the sealing glue can further enhance the waterproof and dustproof effect, protect the microphone from physical damage, and prolong the service life of the earphone.

[0103] Of course, the first and second sealing members can also adopt other sealing structures, such as sealing pads, sealing sheets, etc.

[0104] According to an embodiment of the present application, the first and second conductive members 7 and 20 can be flexible circuit boards.

[0105] Specifically, the first conductive member 7 and the second conductive member 20 are flexible printed circuit boards that can bend flexibly to fit within the confined space inside the earphones. The flexible printed circuit boards are electrically connected to the corresponding microphones and extend outside the mounting opening to ultimately connect to the main circuit board 31 inside the earphones.

[0106] The main circuit board 31 processes the electrical signals transmitted from the first microphone 6 and the second microphone 19, performs necessary signal processing (such as amplification, filtering, noise elimination, etc.), and then transmits the processed signals to other components of the headset (such as the speaker 30, Bluetooth module, etc.).

[0107] Of course, the first conductive member 7 and the second conductive member 20 may also be conductive structures such as cables.

[0108] According to one embodiment of the present application, the shortest distance between the first sound inlet 4 and the second sound inlet 15 is between 8 mm and 25 mm, and when the earphones are worn, the two sound inlets are aligned with the user's mouth. This design can reduce the impact of ambient noise and further improve call quality.

[0109] According to one embodiment of the present application, referring to Figure 1 、 Figure 2 and Figure 5 As shown, the shell 1 includes an upper shell 25 and a lower shell 26 connected to each other. The upper shell 25 and the lower shell 26 form a storage space for accommodating various components. The material of the upper shell 25 can be plastic. The upper shell 25 includes a connected first circumferential wall 12 and a first end face 13. The lower shell 26 includes a connected second circumferential wall 27 and a second end face 28. The second circumferential wall 27 is connected to the first circumferential wall 12, and the second end face 28 is arranged opposite to the first end face 13.

[0110] According to one embodiment of the present application, referring to Figure 1 and Figure 5 As shown, the earphone also includes components such as a mounting bracket 29, a speaker 30 and a main circuit board 31 arranged in the shell 1. The second end surface 28 of the lower shell 26 is provided with a sound hole 32. The speaker 30 is mounted on the lower shell 26 and corresponds to the sound hole 32. The diameter of the speaker 30 is between 10 mm and 25 mm. The main function of the speaker 30 is to receive the audio electrical signal from the main circuit board 31, convert the electrical signal into a sound signal, and transmit it to the ear canal through the sound hole 32; the main circuit board 31 is mounted on the mounting bracket 29. The main circuit board 31 is electrically connected to components such as the first conductive member 7, the second conductive member 20 and the speaker 30 for audio processing and phone calls.

[0111] According to one embodiment of the present application, referring to Figure 1As shown, a bass reflex hole 33 is provided on the top of the second peripheral wall 27 of the lower shell 26 , and the bass reflex hole 33 is used to improve the low-frequency sound quality effect.

[0112] According to one embodiment of the present application, referring to Figure 1 and Figure 2 As shown, the earphone further includes an ear hook 34 and a battery compartment 35 , one end of the ear hook 34 is rotatably connected to the housing 1 , and the other end of the ear hook 34 is connected to the battery compartment 35 .

[0113] Specifically, the ear hook 34 can be designed to be arc-shaped to match the ear, and the ear hook 34 can be rotated relative to the shell 1 so that its position can be adjusted to firmly wear the earphones on the ears, preventing the earphones from falling or loosening during the user's exercise.
