Description

Technical Field

[0001] The present invention relates to wearable devices, and more particularly to in-ear wearable devices. Background Art

[0002] In-ear wearable devices currently on the market, such as headphones, block the ear canal when worn, thus forming a closed cavity between the external ear canal and the in-ear wearable device. When the in-ear wearable device blocks the external ear canal, the volume of the ear canal decreases. The sound of the user's speech is transmitted into the ear canal with a smaller volume as the skull vibrates, generating low-frequency resonance, thereby increasing the intensity of the low-frequency sound and forming an ear-blocking effect. Users will feel uncomfortable if they wear in-ear wearable devices for a long time, which will affect the user experience.

[0003] In view of the above situation, the common solutions are as follows: 1. Add vents to in-ear wearable devices; 2. Open vent slots on the outside of in-ear wearable devices; 3. Replace the closed structure with an open structure. These methods can increase ventilation and improve the comfort of the wearer. However, the ventilation method in these solutions is usually uncontrollable, and the vents or vent slots are usually in a normally open state. Although the open structure can solve the ear blocking effect, it requires sacrificing some sound quality. Summary of the invention

[0004] One object of the present invention is to provide an in-ear wearable device capable of improving wearing comfort. Another object of the present invention is to provide an in-ear wearable device capable of adapting to different usage scenarios. Another object of the present invention is to provide an in-ear wearable device capable of achieving ear canal ventilation. Another object of the present invention is to provide an in-ear wearable device capable of defining different audio effects.

[0005] One aspect of the present invention provides an in-ear wearable device, comprising: a shell having a mounting groove formed therein, the mounting groove being communicated with an external environment; a ventilation channel, which is arranged in the shell and configured to be communicated with the mounting groove; and an adjustable ventilation valve device, comprising: a base, which is at least partially arranged in the mounting groove of the shell and includes a through hole communicated with the ventilation channel; and an adjustment component, which is adjustably connected to the base from a side of the base away from the ventilation channel and is configured to be able to open and close the through hole and the ventilation channel of the base by moving up and down relative to the base, so as to control the user's ear when the user wears the in-ear wearable device. The vent passage is connected or sealed with the external environment, wherein the adjusting component is arranged to protrude at least partially from the mounting groove; wherein the adjustable vent valve device also includes a columnar connecting member extending along the axial direction of the mounting groove and a connecting hole cooperating with the columnar connecting member, the columnar connecting member is centrally arranged on one of the base and the adjusting component, and the connecting hole is centrally arranged in the other of the base and the adjusting component, and the adjustable vent valve device is configured to achieve the up and down movement of the adjusting component relative to the base through the cooperation of the columnar connecting member and the connecting hole; wherein the through hole of the base is at least partially arranged on the periphery of the columnar connecting member or the connecting hole located on the base.

[0006] Thus, the in-ear wearable device can open or close the ventilation channel through an adjustable ventilation valve device, which can convert different usage modes to overcome the ear blocking effect, improve the user's wearing comfort, and adapt to different usage scenarios. By configuring the adjustment component to be able to move up and down relative to the base, the user can adjust the degree of connectivity between the ear canal and the external environment according to actual needs, ensuring the best ventilation effect in different usage scenarios. The design of the adjustment component moving up and down relative to the base simplifies the operation mechanism, and the user can easily open and close the through hole and the ventilation channel without complicated operation steps, thereby improving ease of use. In addition, compared with the design in which the adjustment component is simply rotated horizontally relative to the base and does not move up and down to open and close the ventilation channel, the design of the adjustment component moving up and down relative to the base in the present invention is adopted, so that the adjustment component and the base are not always in contact, which not only reduces wear and tear, but also reduces the failure rate, helps to extend the service life of the device, and reduces the occurrence of air leakage. By arranging the columnar connector and the connecting hole in the center, the connection stability between the adjustment component and the base can be improved, and the offset and shaking during the adjustment process can be reduced, making the adjustment more precise and smooth. In addition, by arranging the columnar connector and the connecting hole in the center, the processing and assembly process can be simplified, which is conducive to improving production efficiency and reducing manufacturing costs. By arranging the through hole of the base on the periphery of the columnar connector or the connecting hole, on the one hand, the space utilization rate can be fully improved, a more uniform ventilation effect can be provided, and it helps to improve the air circulation in the ear canal. On the other hand, the through hole of the base is arranged separately from the columnar connector or the connecting hole. Even if there is slight wear between the columnar connector and the connecting hole, it will basically not affect the ventilation of the through hole and basically will not increase leakage. In addition, for in-ear headphones, this layout helps to optimize the sound wave propagation path and improve the acoustic performance.

[0007] According to certain embodiments of the present invention, the columnar connector and the connecting hole are configured to achieve the up and down movement of the adjusting component relative to the base through a threaded connection, the columnar connector is configured as a stud and is arranged on the base, and the connecting hole is configured as a threaded hole and is arranged on the adjusting component; or the columnar connector and the connecting hole are configured to achieve the up and down movement of the adjusting component relative to the base through a threaded connection, the columnar connector is configured as a stud and is arranged on the adjusting component, and the connecting hole is configured as a threaded hole and is arranged on the base.

[0008] Therefore, the threaded connection can make the movement of the adjustment component relative to the base more precise, and the user can make minor adjustments; the threaded connection provides stronger structural stability and reduces the shaking or loosening of the adjustment component during use; the threaded connection allows the user to make continuous adjustments, rather than being limited to a few fixed positions, providing more adjustment options; and compared with the plug-in up and down adjustment method, the present invention adopts a threaded connection between the stud and the threaded hole, and the stud is adjusted and moved up and down in the threaded hole in a rotating manner, which can make the contact position between the stud and the threaded hole less prone to wear, extend the service life of the equipment, and reduce the occurrence of air leakage.

[0009] According to certain embodiments of the present invention, when the columnar connector is disposed on a base, the base includes a supporting portion for supporting the columnar connector and a connecting portion for connecting the supporting portion to an outer peripheral wall of the base, and the through hole of the base is configured to be at least partially located on the periphery of the supporting portion of the base.

[0010] According to certain embodiments of the present invention, when the connecting hole is provided on the base, the base includes a supporting seat with a connecting hole and a connecting portion for connecting the supporting portion and the outer peripheral wall of the base, and the through hole of the base is configured to be at least partially located on the periphery of the supporting portion of the base.

[0011] Therefore, the design of the supporting part and the connecting part of the base can enhance the overall structural strength of the base without affecting the ventilation effect; and the through holes are arranged to be located on the periphery of the supporting part, which can fully utilize the space and provide a more uniform ventilation effect.

[0012] According to some embodiments of the present invention, an effective ventilation area of ​​the through hole of the base is greater than or equal to an effective ventilation area of ​​the ventilation channel.

[0013] Thus, the larger effective ventilation area of ​​the through hole can ensure sufficient air circulation to effectively improve the ventilation conditions in the ear canal, and can reduce the resistance of airflow to improve the ventilation efficiency. In addition, the through hole has a larger effective ventilation area, which can reduce the risk of the through hole being blocked by earwax or other impurities, ensure continuous ventilation effect, and help dissipate heat and moisture in the ear canal.

[0014] According to some embodiments of the present invention, the mounting groove has a groove width and a groove depth, the groove depth is 0.5-2 mm greater than the height of the portion of the base located in the mounting groove, and the groove width is greater than the inner diameter of the ventilation channel.

[0015] Thus, by making the groove depth slightly larger than the height of the base in the mounting groove, appropriate space is provided for the assembly of the base and the adjustable vent valve device, which facilitates installation and adjustment. In addition, by making the groove depth larger than the portion of the base located in the mounting groove and making the groove width larger than the inner diameter of the vent passage, a holding space can be reserved between the base and the bottom of the mounting groove. For example, when the base is connected to the mounting groove of the shell by glue or the like, excess glue can enter the holding space, which can reduce or prevent the glue from flowing into the vent passage and affecting the vent effect and acoustic performance.

[0016] According to certain embodiments of the present invention, the base includes a filter groove opening toward the ventilation channel, and the adjustable ventilation valve device also includes a damping filter, which is arranged in the filter groove of the base to adjust the frequency characteristics of the sound when the sound passes through the damping filter.

[0017] Thus, the damping filter can adjust the frequency characteristics of the sound, thereby providing a better auditory experience. In addition, the damping filter can be designed to be replaceable to increase the adjustability and adaptability of the device.

[0018] According to some embodiments of the present invention, the adjustable vent valve device further comprises a sealing component, which is disposed on a side of the adjusting component facing the base and is configured to be sealingly engaged with the base when the adjusting component closes the through hole and the vent passage.

[0019] Thus, the sealing component can achieve a tight fit between the adjusting component and the base, and avoid direct contact between the adjusting component and the base, thereby reducing wear and leakage, and improving sealing and reliability. The sealing component can also enable the adjustable ventilation valve device to more accurately control the opening and closing state of the ventilation channel and optimize the ventilation effect. The sealing component can also reduce the interference of external noise when closing the ventilation channel, thereby improving audio quality.

[0020] According to certain embodiments of the present invention, the adjustable ventilation valve device also includes a limiting component, which includes a retaining spring connected to the columnar connecting member and a stop portion arranged on an adjusting component or a base having a connecting hole, and the retaining spring and the stop portion are arranged to cooperate with each other to limit the up and down movement range of the adjusting component relative to the base.

[0021] Therefore, the cooperation between the retaining spring and the stopper of the limiting component limits the moving range of the adjusting component, which can prevent damage or malfunction caused by excessive adjustment; and the clear adjustment range can enable the user to perceive the adjustment degree more intuitively and avoid blind adjustment.

[0022] According to some embodiments of the present invention, the adjusting component includes an operating portion exposed to the mounting groove of the housing and a textured portion disposed on an outer peripheral surface of the operating portion to facilitate operation of the adjusting component.

[0023] Thus, the operating portion is exposed from the shell, so that the user can easily contact and operate the adjustment component, and the texture portion provides better anti-slip performance, thereby improving the stability and accuracy of the operation.

[0024] According to some embodiments of the present invention, a diameter of the ventilation channel is greater than 0 mm and less than or equal to 3 mm.

[0025] Therefore, a ventilation channel diameter of 0-3mm can make the resonance frequency high and thus make the ear-blocking effect lighter; it can effectively and moderately ventilate, thereby reducing the pressure in the ear and reducing the discomfort of long-term wearing; and the ventilation channel of appropriate size can reduce earwax accumulation and extend the service life of the device.

[0026] According to some embodiments of the present invention, the base has a substantially cylindrical outer circumferential surface, the mounting groove has a substantially cylindrical inner circumferential surface, and the base and the mounting groove are respectively provided with mutually cooperating positioning parts to prevent the base from rotating in the mounting groove.

[0027] Therefore, the cooperation between the cylindrical design and the positioning part ensures the stability of the base in the installation groove, reducing shaking and wear; the design that prevents the base from rotating makes the adjustment more precise and the user can better control the ventilation degree; and the cylindrical structure is easy to install, while the positioning part design ensures the correct installation position and reduces installation errors.

[0028] According to some embodiments of the present invention, when the columnar connector is disposed on the base, the adjustable vent valve device further comprises a cover plate connected to a side of the adjusting component away from the base to cover the columnar connector extending from the connecting hole of the adjusting component.

[0029] Thus, the cover plate covers the protruding columnar connector, making the appearance of the device more neat and beautiful; and the cover plate can protect the columnar connector from the influence of the external environment, such as dust, moisture, etc., to extend the life of the device.

[0030] According to some embodiments of the present invention, the adjustable vent valve device is configured to be detachably disposed in a mounting groove of the housing through a base.

[0031] Therefore, it is possible to disassemble and install the adjustable ventilation valve device as required, which facilitates replacement of components of the adjustable ventilation valve device and improves the flexibility and adaptability of use.

[0032] According to an embodiment of the present invention, the adjustable ventilation valve device is configured so that when the user wears the in-ear wearable device, the adjustable ventilation valve device is located at the inter-tracheal notch of the user.

[0033] Thus, the adjustable vent valve device is located at the intertragus notch and close to the entrance of the external auditory canal, so the ventilation path from the external environment to the inside of the auditory canal is greatly shortened, which can improve the ventilation efficiency and also reduce the loss of sound in the ventilation channel. In addition, the intertragus notch is a position that is easier to reach from the outside of the ear, and the adjustable vent valve device is arranged there, so that the user can easily reach and operate the adjustable vent valve device with fingers.

[0045] Hereinafter, embodiments of the present invention are described with reference to the accompanying drawings. The following detailed description and the accompanying drawings are used to exemplarily illustrate the principles of the present invention, and the present invention is not limited to the preferred embodiments described. The scope of the present invention is defined by the claims. The present invention is now described in detail with reference to exemplary embodiments, and some embodiments are illustrated in the accompanying drawings. The following description is made with reference to the accompanying drawings, and unless otherwise indicated, the same reference numerals in different drawings represent the same or similar elements. The schemes described in the following exemplary embodiments do not represent all schemes of the present invention. On the contrary, these schemes are merely examples of systems and methods of various aspects of the present invention involved in the appended claims.

[0046] The present invention provides an in-ear wearable device. The in-ear wearable device can be inserted into the user's ear, especially the user's external auditory canal, to provide the user with various functions, such as audio reproduction, sound reception, health monitoring, etc. The structure and principle of the in-ear wearable device will be described in detail below, taking the in-ear earphone as an example. However, it should be understood that the in-ear wearable device of the present invention is not limited to in-ear earphones. For example, the in-ear wearable device may also be a hearing aid or other device with an audio reproduction function, which is not specifically limited here. For another example, in addition to the audio reproduction function, the in-ear wearable device may be additionally or alternatively implemented as having functions such as sound reception, temperature detection, blood pressure detection, heart rate detection, blood sugar detection, and blood oxygen detection. In addition, in some embodiments, the in-ear wearable device may not be implemented as an in-ear earphone, that is, it does not have an audio reproduction function, but only has other functions.

[0047] Figure 1 is a perspective view of an in-ear headphone according to an embodiment of the present invention. Figure 2 It is a schematic diagram and a partially enlarged schematic diagram of the wearing state of the in-ear earphone according to an embodiment of the present invention. Figure 3 is a schematic cross-sectional view of an in-ear earphone according to an embodiment of the present invention.

[0048] exist Figures 1 to 3 Only one earphone (for example, the left earphone) is shown in the figure, but those skilled in the art understand that a pair of earphones usually consists of two left and right earphones, and their structures are basically symmetrical. Therefore, for simplicity, only one earphone is shown in the figure, and the following description is also only for one earphone.

[0049] like Figure 1 and Figure 3 As shown, the in-ear earphone 10 according to the embodiment of the present invention includes a housing 100, a ventilation channel 200 ( Figure 1 ) and an adjustable ventilation valve device 300.

[0050] In an exemplary embodiment, the shell 100 may be a customized shell. In this article, "customized" means that the shell is individually designed and manufactured for the ears of different users, rather than being uniformly designed and manufactured. A customized shell may, for example, be manufactured by taking an ear mold from the user's ear and then using a manufacturing device based on the taken ear mold. The customized shell may be manufactured by 3D printing or by other manufacturing methods. The size of the customized shell may be the same as the taken ear mold, or it may be slightly smaller than the taken ear mold to improve the wearing comfort of some sensitive users. In some embodiments, the shell 100 may not be a customized shell, and the present application does not specifically limit the type of shell.

[0051] According to some embodiments of the present invention, the housing 100 includes a first portion for being inserted into the ear canal of the user and matching the shape of the ear canal and a second portion exposed to the external environment when the first portion is inserted into the ear canal. The second portion of the housing 100 is a portion exposed to the external environment when the user wears the in-ear earphone 10, so as to provide an operating space for the adjustable ventilation valve device 300.

[0052] According to an embodiment of the present invention, Figure 3 As shown, a mounting groove 110 is formed inside the shell 100, and the mounting groove 110 is connected to the external environment. The ventilation channel 200 is disposed in the shell 100 and is configured to be connected to the mounting groove 110 of the shell 100. The diameter of the ventilation channel 200 is greater than 0 mm and less than or equal to 3 mm. Preferably, the diameter of the ventilation channel 200 is 2 mm. Thus, the ventilation channel diameter of 0-3 mm can make the resonance frequency high and thus make the ear blocking effect lighter; it can effectively and moderately ventilate, thereby reducing the pressure in the ear and reducing the discomfort of wearing for a long time; and the ventilation channel of appropriate size can reduce earwax accumulation and extend the service life of the device. In some embodiments, the ventilation channel 200 is completely disposed in the shell wall 120 (described below) of the shell 100, such as Figure 3 For example, the ventilation channel 200 may be formed when the housing 100 is manufactured, or may be additionally formed in the housing wall after the housing 100 is manufactured. In some embodiments, the ventilation channel 200 includes an independent pipe connected to the housing 100 by assembly.

[0053] In some embodiments, the vent channel 200 is configured to communicate with the front cavity of the in-ear earphone 10 and to communicate with the sound outlet of the in-ear earphone 10 through the front cavity. In this case, the vent channel 200 communicates with the external auditory canal via the front cavity of the in-ear earphone 10. In some embodiments, one end of the vent channel 200 communicates with the adjustable vent valve device 300 and the other end communicates directly with the external auditory canal of the user wearing the in-ear earphone 10. In this case, the vent channel 200 directly communicates with the external auditory canal.

[0054] According to an embodiment of the present invention, the housing 100 includes a housing wall 120 and an inner cavity 130 surrounded by the housing wall 120. In some embodiments, the in-ear earphone 10 may further include components such as a mainboard, a control device, a charging device, a battery, an antenna device, a magnet, a sound pickup device, a speaker assembly, and a wireless communication module. The various components may be assembled together by bolts, welding, gluing, snapping, etc. These components may be arranged in the inner cavity 130 of the housing 100.

[0055] According to an embodiment of the present invention, the adjustable ventilation valve device 300 is configured to be operated to open and close the ventilation channel 200. When a user wears an in-ear earphone with a customized shell, when the ventilation channel is closed, the external auditory canal is sealed by the shell, so that the user can have a better listening effect, for example, of music. However, when the ventilation channel is closed, due to the influence of the ear blocking effect, the ear canal is sealed by the shell, resulting in different air pressures inside and outside the ear canal, causing the user to feel uncomfortable when wearing for a long time or to hear unnatural sounds. By opening or closing the ventilation channel 200 through the adjustable ventilation valve device 300, different usage modes can be converted to overcome the ear blocking effect, improve the user's wearing comfort, and adapt to different usage scenarios.

[0056] In an exemplary embodiment, the adjustable vent valve device 300 is configured so that when the user wears the in-ear earphone 10, the adjustable vent valve device 300 is located at the user's interalar notch, such as Figure 2 As shown. Since the adjustable ventilation valve device 300 is located at the intertragus notch and close to the entrance of the external auditory canal, the ventilation path from the external environment to the inside of the external auditory canal is greatly shortened, which can improve the ventilation efficiency and also reduce the loss of sound in the ventilation channel. In addition, the intertragus notch is a position that is easier to reach from the outside of the ear. The adjustable ventilation valve device 300 is arranged here so that the user can easily reach and operate the adjustable ventilation valve device with his fingers.

[0057] According to an embodiment of the present invention, the adjustable vent valve device 300 includes a base 310 and an adjusting component 320. The adjusting component 320 can move relative to the base 310 to open or close the vent channel 200. The adjustable vent valve device 300 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] Figure 4 4 is a schematic cross-sectional view of an adjustable ventilation valve device of an in-ear earphone according to an embodiment of the present invention. Figure 5 2 is a schematic exploded view of an adjustable ventilation valve device of an in-ear earphone according to an embodiment of the present invention. Figure 6 is a side view of an adjustable vent valve device according to an embodiment of the present invention.

[0059] Figure 7is a top view of an adjustable ventilation valve device according to an embodiment of the present invention. Figure 8 Schematic diagram of a closed state of an adjustable ventilation valve device of an in-ear earphone according to an embodiment of the present invention. Fig. 9 Schematic diagram of an open state of an adjustable ventilation valve device of an in-ear earphone according to an embodiment of the present invention.

[0060] According to an embodiment of the present invention, Figure 3 , Figure 8 and Fig. 9 As shown, the base 310 is at least partially disposed in the mounting groove 110 of the housing 100 and includes a through hole 311 communicating with the ventilation channel 200. Thus, the ventilation channel 200 can communicate with the external environment through the through hole 311 of the base 310.

[0061] According to an embodiment of the present invention, Figure 3 and Figure 4 As shown, the adjustment component 320 is adjustably connected to the base 310 from a side of the base 310 away from the ventilation channel 200. The adjustment component 320 is configured to be able to move up and down relative to the base 310, so as to open and close the through hole 311 of the base 310 and the ventilation channel 200, and then control the communication or sealing of the user's ear canal with the external environment when the user wears the in-ear earphone 10.

[0062] According to an embodiment of the present invention, Figure 3 , Figure 8 and Fig. 9 As shown, the adjustment component 320 is configured to at least partially protrude from the mounting groove 110 of the housing 100. Therefore, the user can conveniently touch and operate the adjustment component 320 when wearing the in-ear earphone 10, and can more accurately control the upward and downward movement of the adjustment component 320 relative to the base 310, thereby achieving the opening and closing adjustment of the through hole 311 and the ventilation channel 200.

[0063] In some embodiments, Figure 4 and Figure 5 As shown, the adjustable vent valve device 300 further includes a columnar connector 331 extending in the axial direction of the mounting groove 110 and a connecting hole 332 cooperating with the columnar connector 331. The adjustable vent valve device 300 is configured to achieve the up and down movement of the adjustment component 320 relative to the base 310 through the cooperation of the columnar connector 331 and the connecting hole 332. In an exemplary embodiment, the columnar connector 331 and the connecting hole 332 are configured to achieve the up and down movement of the adjustment component 320 relative to the base 310 through threaded connection. In this case, the columnar connector 331 can be configured as a stud, and the connecting hole 332 can be configured as a threaded hole.

[0064] During use, the user can rotate or push and pull the adjustment component 320 to move it up and down relative to the base 310. When the adjustment component 320 moves downward relative to the base 310, the through hole 311 of the base 310 will gradually be covered, thereby reducing or blocking the connection between the user's ear canal and the external environment. Figure 8 When the adjustment component 320 moves upward relative to the base 310, the through hole 311 gradually opens, increasing the connection between the user's ear canal and the external environment, as shown in FIG. Fig. 9 As shown. When the adjustment component 320 moves upward relative to the base 310, the through hole 311 and the ventilation channel 200 are gradually opened; and when the adjustment component 320 moves downward relative to the base 310, the through hole 311 and the ventilation channel 200 are gradually opened. Through this design, the user can clearly perceive the changes in the opening and closing states of the ventilation channel through the operating feel during the adjustment process, thereby achieving an operating experience that is more in line with the user's cognition and usage habits.

[0065] By configuring the adjustment component 320 to be able to move up and down relative to the base 310, the user can adjust the degree of connectivity between the ear canal and the external environment according to actual needs, ensuring the best ventilation effect in different usage scenarios. The design of the adjustment component 320 moving up and down relative to the base 310 simplifies the operation mechanism, and the user can easily open and close the through hole 311 and the ventilation channel 200 without complicated operating steps, thereby improving ease of use. In addition, compared with the design in which the adjustment component simply rotates horizontally relative to the base and does not move up and down to open and close the ventilation channel, the design of the adjustment component 320 moving up and down relative to the base 310 adopted in the present invention makes the adjustment component 320 not always in contact with the base 310, which reduces wear and tear, reduces the failure rate, helps to extend the service life of the equipment, and reduces the occurrence of air leakage.

[0066] In some embodiments, Figure 4 and Figure 5 As shown, the columnar connector 331 is disposed on the base 310, and the connection hole 332 is disposed in the adjustment component 320. In an exemplary embodiment, the columnar connector 331 is centrally disposed on the base 310, and the connection hole 332 is centrally disposed in the adjustment component 320. By centrally arranging the columnar connector 331 and the connection hole 332, the connection stability between the adjustment component 320 and the base 310 can be improved, and the offset and shaking during the adjustment process can be reduced, making the adjustment more precise and smooth. In addition, by centrally arranging the columnar connector 331 and the connection hole 332, the processing and assembly process can be simplified, which is conducive to improving production efficiency and reducing manufacturing costs.

[0067] In some embodiments, more specifically, Figure 4 and Figure 5As shown, the through hole 11 of the base 10 is at least partially arranged on the periphery of the columnar connector 331 located on the base 10. By arranging the through hole 11 of the base 10 on the periphery of the columnar connector 331, on the one hand, the space utilization rate can be fully improved, and a more uniform ventilation effect can be provided and help improve the air circulation in the ear canal. On the other hand, the through hole 11 of the base 10 is arranged separately from the columnar connector 331. Even if there is slight wear between the columnar connector 331 and the connecting hole 332, it will basically not affect the ventilation of the through hole 11 and basically will not increase leakage. In addition, for in-ear headphones, this layout helps to optimize the sound wave propagation path and improve the acoustic performance.

[0068] When a threaded connection is used to achieve the up and down movement of the adjusting component 320 relative to the base 310, the threaded connection can make the movement of the adjusting component 320 relative to the base 310 more precise, and the user can make minor adjustments; the threaded connection provides stronger structural stability and reduces the shaking or loosening of the adjusting component 320 during use; the threaded connection allows the user to make continuous adjustments, rather than being limited to a few fixed positions, providing more adjustment options; and compared with the plug-in up and down adjustment method, the present invention uses a threaded connection between a stud and a threaded hole, and the stud is adjusted and moved up and down in the threaded hole in a rotating manner, which can make the contact position between the stud and the threaded hole less prone to wear, extend the service life of the equipment, and reduce the occurrence of air leakage.

[0069] In some embodiments, more specifically, Figure 5 As shown, the base 310 includes a support portion 333 for supporting a columnar connector 331 and a connection portion 334 for connecting the support portion 333 with the outer peripheral wall of the base 310, and the through hole 311 of the base 310 is configured to be at least partially located at the periphery of the support portion 333 of the base 310. The design of the support portion 333 and the connection portion 334 of the base 310 can enhance the overall structural strength of the base 310 without affecting the ventilation effect. The through hole 311 is arranged to be located at the periphery of the support portion 333, which can make full use of the space and provide a more uniform ventilation effect.

[0070] According to an embodiment of the present invention, the effective ventilation area of ​​the through hole 311 of the base 310 is greater than or equal to the effective ventilation area of ​​the ventilation channel 200. The larger effective ventilation area of ​​the through hole 311 can ensure sufficient air circulation to effectively improve the ventilation conditions in the ear canal, and can reduce the resistance when the airflow passes through to improve the ventilation efficiency. In addition, the through hole has a larger effective ventilation area, which can reduce the risk of the through hole being blocked by earwax or other impurities, ensure a continuous ventilation effect, and can help dissipate heat and moisture in the ear canal.

[0071] According to an embodiment of the present invention, Figure 8As shown, the mounting groove 110 of the housing 100 has a groove width W and a groove depth H, the groove depth H is set to be 0.5-2mm greater than the height of the portion of the base 310 located in the mounting groove 110, preferably 1mm greater, and the groove width W is greater than the inner diameter of the ventilation channel 200. By making the groove depth H of the mounting groove 110 slightly greater than the height L of the base 310 in the mounting groove 110, a suitable space is provided for the assembly of the base 310 and the adjustable ventilation valve device 300, which is convenient for installation and adjustment. In addition, by making the groove depth H greater than the portion of the base 310 located in the mounting groove 110 and making the groove width W greater than the inner diameter of the ventilation channel 200, an accommodation space can be reserved between the base 310 and the bottom of the mounting groove 110. For example, when the base 310 is connected to the mounting groove 110 of the housing 100 by glue or the like, excess glue can enter the accommodation space, which can reduce or avoid the glue flowing into the ventilation channel 200 and affecting the ventilation effect and acoustic performance.

[0072] According to an embodiment of the present invention, the adjustable vent valve device 300 can be detachably disposed in the mounting groove 110 of the housing 100 through the base 310. Thus, the adjustable vent valve device 300 can be disassembled and installed as needed, which is convenient for replacing components of the adjustable vent valve device 300 and improves the flexibility and adaptability of use.

[0073] According to an embodiment of the present invention, the adjustable vent valve device 300 may further include a damping filter 340. The damping filter 340 may damp the sound passing through it to improve the sound frequency characteristics. In some embodiments, the damping filter 340 may be made of woven cloth, woven steel mesh, etched mesh plate, etc. The damping filter 340 may be connected (e.g., pasted) to the housing 100 or the adjustable vent valve device 300. In some embodiments, the damping filter 340 may be connected to the adjustable vent valve device 300. More specifically, the damping filter 340 may be connected to the lower end of the base 310 or to the filter groove of the base 310. The damping filter 340 may be pasted to the lower end of the base.

[0074] The following is a detailed description of the embodiment in which the damping filter 340 is connected to the filter slot of the base 310 with reference to the accompanying drawings. Figure 4As shown, the base 310 includes a filter slot 312 with an opening toward the ventilation channel 200, and a damping filter 340 is arranged in the filter slot 312 of the base 310, so as to adjust the frequency characteristics of the sound when the sound passes through the damping filter 340. The damping filter 340 can adjust the frequency characteristics of the sound, thereby providing a better auditory experience. By connecting the damping filter 340 to the filter slot 312 of the base 310, the design of the filter slot 312 ensures that the damping filter 340 can be accurately positioned on the base 310, preventing the damping filter 340 from being offset during installation; and the filter slot 312 provides a fixed position, so that the damping filter 340 will not be easily moved or fallen off during use, thereby ensuring the stability of the damping filter 340. In addition, the damping filter 340 can be designed to be replaceable to increase the adjustability and adaptability of the device.

[0075] According to an embodiment of the present invention, the adjustable vent valve device 300 may further include a sealing component 350. The sealing component 350 is disposed on a side of the adjusting component 320 facing the base 310, such as Figure 4 and Figure 5 As shown. When the adjusting component 320 moves downward relative to the base 310 to close the through hole 311 of the base 310 and the ventilation channel 200, the sealing component 350 can be sealed and engaged with the base 310. The sealing component 350 can achieve a close engagement between the adjusting component 320 and the base 310, and avoid direct contact between the adjusting component and the base, reduce the occurrence of wear and leakage, and improve the sealing performance and reliability. The sealing component 350 can also enable the adjustable ventilation valve device 300 to more accurately control the opening and closing state of the ventilation channel 200 and optimize the ventilation effect. The sealing component 350 can also reduce the interference of external noise when closing the ventilation channel 200, thereby improving the audio quality.

[0076] In some embodiments, the sealing component 350 is made of an elastic material, such as a soft rubber material. Since the elastic material has good elasticity and flexibility, the sealing component 350 can fit closely to the base 310 to ensure a sealing effect. The elastic material can also have a certain buffering effect to improve wearing comfort.

[0077] In some embodiments, the sealing component 350 is at least partially sleeved on the adjusting component 320 and is integrally formed with the adjusting component 320. For example, the sealing component 350 can be formed by insert molding on the prefabricated adjusting component 320. By integrally forming the sealing component 350 with the adjusting component 320, the connection stability can be improved and the sealing effect can be improved, and the assembly process can also be simplified.

[0078] According to an embodiment of the present invention, the adjustable vent valve device 300 further includes a limiting component. Figure 4 and Figure 5 As shown, the limiting component includes a spring 361 connected to the columnar connecting member 331 and a stopper 362 provided on the adjusting component 320 having a connecting hole 332. When the adjusting component 320 moves up and down relative to the base 310, the spring 361 and the stopper 362 can cooperate with each other to limit the upward and downward movement range of the adjusting component 320 relative to the base 310.

[0079] According to an embodiment of the present invention, the adjustment component 320 includes an operation portion 321 exposed to the mounting groove 110 of the housing 100 and a texture portion 322 provided on the outer peripheral surface of the operation portion 321, so that the user can operate the adjustment component 320. The texture portion 322 can be a knurled texture. The operation portion 321 is exposed to the housing 100, so that the user can easily contact and operate the adjustment component 320. The texture portion 322 provides better anti-slip performance and improves the stability and accuracy of the operation.

[0080] In some embodiments, the base 310 has a substantially cylindrical outer peripheral surface, and the mounting groove 110 has a substantially cylindrical inner peripheral surface, such as Figure 5 As shown. The cylindrical design can simplify the assembly process of the base 310 and the mounting groove 110 and improve stability, and can also make disassembly more convenient. In an exemplary embodiment, the base 310 and the mounting groove 110 are respectively provided with mutually cooperating positioning parts to prevent the base 310 from rotating in the mounting groove 110. Figure 5 As shown, the base 310 includes a positioning portion 313. The positioning portions of the base 310 and the mounting groove 110 can be planar positioning portions, respectively. In an exemplary embodiment, the base 310 and the mounting groove 110 include two planar positioning portions, respectively. The two planar positioning portions of the base 310 can be formed by cutting off a piece at two corresponding positions on the periphery of the base 310. The planar positioning portion of the mounting groove 110 can be formed as a planar convex portion protruding from the inner wall of the mounting groove 110 toward the base 310. Through the mutual cooperation of the planar positioning portion and the planar convex portion, the precise positioning of the base 310 in the mounting groove 110 can be achieved. Compared with other types of positioning portions, the manufacturing process of the planar positioning portion is simple, easy to process and position, and provides a stable and reliable positioning effect without affecting the installation.

[0081] In some embodiments, the adjustable vent valve device 300 further includes a cover plate 370. The cover plate 370 is connected to a side of the adjustment component 320 away from the base 310 to cover the columnar connecting member 331 extending from the connecting hole 332 of the adjustment component 320. Figure 4 and Figure 5 The cover plate 370 mainly serves the purpose of decoration and protection.

In addition, by centrally arranging the columnar connector 331 and the connection hole 332, the processing and assembly process can be simplified, which is conducive to improving production efficiency and reducing manufacturing costs.

[0084] In some embodiments, more specifically, the through hole 311 of the base 310 is at least partially disposed on the periphery of the connection hole 332 located in the base 310. By disposing the through hole 311 of the base 310 on the periphery of the connection hole 332, the space utilization rate can be fully improved, a more uniform ventilation effect can be provided, and the air circulation in the ear canal can be improved. In addition, for in-ear headphones, this layout helps to optimize the sound wave propagation path and improve the acoustic performance.

[0085] In some embodiments, more specifically, Fig.11 As shown, the base 310 includes a support seat 333 with a connection hole 332 and a connection portion 334 for connecting the support portion 333 and the outer peripheral wall of the base 310, and the through hole 311 of the base 310 is configured to be at least partially located at the periphery of the support portion 333 of the base 310.
