[0050] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following detailed description and drawings are used to illustratively explain the principles of the present invention, and the present invention is not limited to the described preferred embodiments. The scope of the present invention is limited by the claims. Hereinafter, the present invention will be described in detail with reference to exemplary embodiments, some of which are illustrated in the drawings. The following description will be made with reference to the drawings, and unless otherwise specified, the same reference numerals in different drawings represent the same or similar parts. The aspects described in the following exemplary embodiments do not represent all aspects of the present invention. On the contrary, these aspects are merely examples of systems and methods of various aspects of the present invention according to the appended claims.

[0051] The present invention provides an in-ear wearable device. The in-ear wearable device is inserted into a user's ear, particularly the user's ear canal, and can provide the user with various functions, such as audio playback, voice reception, health monitoring, etc. The structure and principles of the in-ear wearable device will be described in detail below, taking in-ear wireless earphones as an example. However, it should be understood that the in-ear wearable device of the present invention is not limited to in-ear wireless earphones. For example, in addition to the audio playback function, the in-ear wearable device can additionally or alternatively implement functions such as voice reception, temperature detection, blood pressure detection, heart rate detection, blood glucose detection, and blood oxygen detection. Furthermore, in some embodiments, the in-ear wearable device may not be an in-ear wireless earphone, i.e., it may be implemented as a device having only other functions without the audio playback function.

[0052] FIG. 1 is a perspective view of an in-ear wireless earphone 10 according to an embodiment of the present invention. Although FIG. 1 shows only one earphone (e.g., a left earphone), those skilled in the art will understand that a pair of earphones typically consists of two earphones with a symmetrical structure. Therefore, for simplicity, only one earphone is shown in the drawings, and the following description will also focus on only one earphone. The in-ear wireless earphone 10 has a first side 10A and a second side 10B. The first side 10A of the in-ear wireless earphone 10 represents the side that is in the user's ear canal when the in-ear wireless earphone 10 is worn by a user, and the second side 10B of the in-ear wireless earphone 10 represents the side that is exposed to the external environment when the in-ear wireless earphone 10 is worn by a user. As shown in FIG. 1, the first side 10A of the in-ear wireless earphone 10 is located at the bottom, and the second side 10B is located at the top.

[0053] Referring to FIG. 1, an in-ear wireless earphone 10 according to an embodiment of the present invention includes a custom housing 100 and a panel 200. FIG. 2 is a perspective view of a custom housing for an in-ear wireless earphone according to an embodiment of the present invention. As used herein, "custom" means that the housing is designed and manufactured to fit each user's ear, rather than being uniformly designed and manufactured. The custom housing 100 can be manufactured, for example, by taking an ear impression of the user's ear and using a manufacturing device based on the ear impression. The custom housing 100 can be manufactured by 3D printing or other manufacturing methods. The size of the custom housing 100 can be the same as the acquired ear impression, or it can be slightly smaller than the acquired ear impression to improve wearing comfort for some sensitive users.

[0054] When a user wears a standard earphone, the size of the standard earphone is fixed. Therefore, the size must be minimized to accommodate the ear size (e.g., the concha) of many users. However, to ensure stable wear and prevent the earphone from falling off, a protrusion must be provided to securely fasten the earphone to the ear. In this case, standard earphones place pressure on the ear canal or part of the ear cavity of many users when worn, causing discomfort due to prolonged wear. For example, many users experience discomfort after wearing standard earphones for 30 minutes or even shorter. In contrast, the custom housing 100 of the in-ear wireless earphone 10 of the present invention is customized for the user and hardly places pressure on the user's ear. Therefore, compared to standard earphones, the in-ear wireless earphone 10 of the present invention is more comfortable to wear and allows users to wear the earphone for extended periods of time, such as several hours or even longer. Furthermore, since users can wear the earphones for extended periods of time, in addition to traditional video services, users are more likely to use them in a variety of situations, such as audio and video calls, games, and various virtual reality activities.

[0055] In an exemplary embodiment, custom housing 100 is a one-piece structure or formed in one piece, i.e., formed at one time based on a user's ear impression. In other embodiments, custom housing 100 may be comprised of multiple parts, such as a core portion and a custom fit portion, where the core portion is the same for all or multiple users and may be assembled together with panel 200, and the custom fit portion is formed based on the user's ear impression. When custom housing 100 includes a core portion and a custom fit portion, productivity can be improved because the components other than the custom fit portion are the same for multiple users.

[0056] According to one embodiment of the present invention, the custom housing 100 includes a first portion that is inserted into a user's ear canal and conforms to the shape of the ear canal, and a second portion that is exposed to the external environment when the first portion is inserted into the ear canal. By "custom," we mean that when a user wears the in-ear wireless earphones 10, the custom housing 100 at least partially fits tightly against the user's ear canal. This allows the first portion of the custom housing 100 to fit tightly against the user's ear canal, i.e., to be shielded from the external environment, thereby providing a sealed listening environment within the ear canal when the user wears the in-ear wireless earphones 10. The second portion of the custom housing 100 is exposed to the external environment when the user wears the in-ear wireless earphones 10, providing access to an airflow adjustment device (described in more detail below). In one embodiment, the second portion of the custom housing 100 has an open end. The open end is located on the side of the second portion that is away from the first portion. In one embodiment, a panel 200 is attached to the custom housing 100 at the open end of the second portion of the custom housing 100. For example, the open end allows other components of the in-ear wireless earphone 10 to be placed inside the custom housing 100, and then the panel 200 is attached to the open end.

[0057] According to one embodiment of the present invention, custom housing 100 includes housing wall 110 and cavity 120 surrounded by housing wall 110. In one embodiment, in-ear wireless earphone 10 may further include components such as a main board, an operating device, a charging device, a battery, an antenna device, a magnet, a sound pickup device, a speaker assembly, and a wireless communication module. Each component may be assembled together by bolts, welding, adhesives, fittings, or the like. These components may be disposed within a space surrounded by custom housing 100 and panel 200. Specifically, these components are primarily located within cavity 120 of custom housing 100, and panel 100 may be used to seal cavity 120. As long as the other components function properly, panel 200 may be a flat cover plate or a concave or other non-flat cover plate. In an exemplary embodiment, panel 200 is attached to custom housing 100 on second side 10B of in-ear wireless earphone 10.

[0058] 2, the custom housing 100 may include a first protrusion 130 and a second protrusion 140. When a user wears the in-ear wireless earphone 10, the first protrusion 130 may be positioned in the user's concha cavity or the user's concha cavity and ear canal, and the second protrusion 140 may be positioned in the user's concha navicularis. The first protrusion 130 may include an opening, and the speaker assembly may be positioned within the first protrusion 140 at a location proximate the opening. This allows sound output from the speaker assembly's audio output device to pass through the opening and enter the user's ear canal.

[0059] FIG. 3 is a cross-sectional schematic diagram of an in-ear wireless earphone according to an embodiment of the present invention. According to an embodiment of the present invention, the in-ear wireless earphone includes an air vent 300 and an airflow adjustment device 400. The air vent 300 is at least partially (i.e., at least partially) disposed within the custom housing 100, i.e., is at least partially formed by the custom housing 100. In one embodiment, the segment of the air vent 300 disposed within the custom housing 100 is formed within the housing wall 110. For example, the segment of the air vent 300 disposed within the custom housing 100 may be formed during the manufacturing of the custom housing 100, or may be additionally formed within the housing wall 110 after the manufacturing of the custom housing 100. In one embodiment, the air vent has a diameter of 0.8 to 3.0 mm, for example, 2.0 mm. According to an embodiment of the present invention, the air vent 300 is disposed entirely within the custom housing 100, as shown in FIG. 3. In an exemplary embodiment, the air vent 300 is disposed entirely within the housing wall 110 of the custom housing 100. The vent 300 has a first opening 300A that is exposed to the user's ear canal when the user wears the in-ear wireless earphone 10, and a second opening 300B that is exposed to the external environment. Thus, the first opening 300A is located on the first side 10A of the ear-type wireless earphone 10, and the second opening 300B is located on the second side 10B of the in-ear wireless earphone 10. In some embodiments, the vent 300 is a straight vent. In some embodiments, the vent 300 is a folded vent. A folded vent can provide a longer vent length in a relatively smaller volume than a straight vent, making it suitable for smaller-volume in-ear wireless earphones 10 or custom housings 100.

[0060] According to one embodiment of the present invention, the airflow regulator 400 is mounted within the air vent 300. The air vent 300 and the airflow regulator 400 form at least a portion of an airway that is isolated from the lumen 120 of the custom housing 100. As used herein, "isolated" refers to the lack of fluid communication between the airway and the lumen 120 of the custom housing 100 when a user wears the in-ear wireless earphones 10 (i.e., when a first portion of the custom housing 100 is inserted into the user's ear canal). The airway is configured to provide fluid communication between the user's ear canal and the external environment when the user wears the in-ear wireless earphones 10. This allows the airway to provide fluid communication between the first side 10A and the second side 10B of the in-ear wireless earphones. By isolating the air passage from the inner cavity 120 of the custom housing 100, the influence of the ventilation airflow on the internal components and sound quality of the in-ear wireless earphone during ventilation through the air passage can be avoided or reduced, and the applicability and stability of the in-ear wireless earphone in different modes can be improved.

[0061] In one embodiment, the airflow regulator 400 is located at the second opening 300B of the vent 300, i.e., at the end of the vent 300 that is located on the second side 10B. In another embodiment, the airflow regulator 400 is located at a position on the vent 300 that is away from both the first opening 300A and the second opening 300B, i.e., at a middle position of the vent 300.

[0062] According to some embodiments of the present invention, the airway is at least partially located within custom housing 100. In some embodiments, the airway is completely located within custom housing 100. In some embodiments, the airway is a straight passage. In some embodiments, the airway is a folded passage. A folded passage is suitable for placement in smaller housings and in-ear wireless earbuds and can achieve an airway length that is the same or longer than a straight passage.

[0063] According to one embodiment of the present invention, the airflow regulator 400 is configured to manually adjust the airflow rate of the air passage. As used herein, "manual operation" refers to operation performed solely by force applied by the user's hand, rather than by electrical power. Specifically, the airflow regulator 400 can manually open and close the air passage by opening and closing the air vent 300. This allows air to flow through the air passage when the airflow regulator 400 is open, and provides a better listening experience when the airflow regulator 400 is closed.

[0064] When a user wears in-ear wireless earphones with a custom housing, if the air vents are closed, the custom housing seals the ear canal, allowing the user to enjoy a better listening experience, such as listening to music. However, when the air vents are closed, the custom housing seals the ear canal, causing ear clogging, which results in different air pressures inside and outside the ear canal, causing discomfort and unnatural sounds when the user wears the earphones for long periods of time. By opening and closing the air vents 300 with the air vent adjuster 400, the user can change the usage mode, overcome the clogging effect, improve the user's wearing comfort, and adapt to different usage scenarios.

[0065] According to one embodiment of the present invention, the airflow regulator 400 can be manually switched between a fully open state (100%) to fully open the air passage and a fully closed state (0%) to fully close the air passage. In the fully open state, the air passage is fully open, allowing for maximum airflow. In the fully closed state, the air passage is fully closed, preventing airflow.

[0066] In some embodiments, the airflow regulator 400 may be manually operated to one or more partially open states for partially opening the air passage in addition to the fully open and fully closed states. This allows the airflow regulator 400 to have multiple airflow gears. For example, the airflow regulator 400 may be manually operated to a 25% open state, a 50% open state, a 75% open state, etc.

[0067] In one embodiment, the airflow regulator 400 can be manually operated to continuously adjust the airflow rate of the air passage, thereby allowing the airflow regulator 400 to be infinitely adjustable.

[0068] In one embodiment, the airflow adjustment device 400 is configured to adjust the audio characteristics of the in-ear wireless earphone 10 by adjusting the airflow rate of the air passage. Thus, the airflow adjustment device 400 can adjust the airflow rate of the air passage, i.e., the degree to which the air vents are open. When the air passage of the in-ear wireless earphone 10 is completely closed, the in-ear wireless earphone 10 can provide a better noise reduction effect and audio listening experience. When the user operates the airflow adjustment device 400 to open the air passage of the in-ear wireless earphone 10, the air passage is ventilated, allowing the user to avoid ear congestion, receive external environmental sounds more clearly, and improve wearing comfort. Furthermore, when the user operates the airflow adjustment device 400 to set different airflow rates for the air passage, the in-ear wireless earphone 10 can provide different audio characteristics, allowing the user to easily tailor their listening experience to their different needs.

[0069] In some embodiments, the mounting position of the airflow regulator 400 can be located at the first opening 300A or the second opening 300B of the air vent 300. In some embodiments, the mounting position of the airflow regulator 400 can be located at a position away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a middle position of the air vent 300. By mounting the airflow regulator 400 at different positions within the air vent, different in-ear wireless earphones 10 can have different audio cavities, thereby limiting different audio effects to meet personal needs.

[0070] According to one embodiment of the present invention, the airflow adjustment device 400 is located in the second portion of the custom housing 100 and includes an operating unit exposed from the outer surface of the custom housing 100. A user can adjust the airflow rate of the air passage by manually operating the operating unit of the airflow adjustment device 400. By exposing the operating unit of the airflow adjustment device 400 to the external environment when the user wears the in-ear wireless earphones 10, the user can adjust the airflow rate of the air passage by directly operating the airflow adjustment device 400 while wearing the in-ear wireless earphones 10, without having to remove them. This improves user operability and ease of use.

[0071] In one embodiment, the operating unit of the airflow adjustment device 400 is located at the second opening 300B of the air vent 300. By locating the operating unit together with the second opening (outlet) of the air vent 300, the space occupied by the airflow adjustment device 400 on the exterior surface of the in-ear wireless earphone 10 can be reduced, resulting in a more compact structure and reduced manufacturing and assembly costs for the in-ear wireless earphone 10. In one embodiment, the operating unit of the airflow adjustment device 400 is located at a position other than the second opening 300B in the second portion of the custom housing 100. As a result, the operating unit of the airflow adjustment device 400 is not located at the second opening 300B. By locating the operating unit separately from the second opening of the air vent 300, the effect of the user's operation on the airflow at the second opening can be reduced, allowing the user to more accurately sense the effect on audio characteristics caused by adjusting the airflow adjustment device 400.

[0072] According to an embodiment of the present invention, the airflow regulator 400 further includes a movable part and a fixed part, and the movable part can adjust the airflow rate of the air passage by moving relative to the fixed part. Hereinafter, the airflow regulator according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0073] Butterfly valve structure According to an embodiment of the present invention, the airflow adjustment device can adopt a butterfly valve structure. Figure 4A is a perspective view of an in-ear wireless earphone according to an embodiment of the present invention. Figure 4B is a cross-sectional schematic view of an in-ear wireless earphone according to an embodiment of the present invention. Figure 4C is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention. Figure 4D is a cross-sectional schematic view of an airflow adjustment device in an open state according to an embodiment of the present invention. Figure 4E is a cross-sectional schematic view of an airflow adjustment device in a closed state according to an embodiment of the present invention.

[0074] As shown in FIG. 4A , the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. As shown in FIG. 4B , the air vent 300 of the in-ear wireless earphone 10 is disposed within the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400 (not shown in FIG. 4A ). In an exemplary embodiment, as shown in FIG. 4B , the mounting location 300C is located away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a midpoint of the air vent 300. In some embodiments, the mounting location 300C may be located at the second opening 300B of the air vent 300. The other components and configurations of the in-ear wireless earphone 10 are as described above, and will not be described again here.

[0075] In some embodiments, the vent 300 has a generally linear extension at the attachment location 300C, e.g., the vent 300 is a straight vent, or the vent 300 is a folded vent overall but has a straight segment at the attachment location 300C.

[0076] According to one embodiment of the present invention, as shown in FIGS. 4C to 4E , an airflow regulator 400 includes a valve plate 410 as a movable part, a valve body 420 as a fixed part, and a twisting part 430 as an operating part. The valve body 420 includes an opening 421 that communicates with the air vent 300. The valve plate 410 is provided inside the valve body 420. The valve plate 410 is rotatable relative to the valve body 420. In the exemplary embodiment, the rotation axis of the valve plate 410 intersects with, and is, for example, substantially perpendicular to, the extension direction of the air vent 300 in the airflow regulator 400. In this specification, the "extension direction of the air vent 300 in the airflow regulator 400" refers to the extension direction of the segment at the attachment position 300C of the air vent 300, i.e., the center line of the segment at the attachment position 300C of the air vent 300. In the exemplary embodiment, twist 430 is located in the second portion of custom housing 100 at a location other than second aperture 300B.

[0077] In an exemplary embodiment, the airflow regulator 400 further includes a valve plate fixing member 440 disposed on the exterior of the valve body 420, and the valve plate 410 includes an extension 411. The extension 411 passes through the wall of the valve body 420 and is fixedly connected to the valve plate fixing member 440. In one embodiment, as shown in Figures 4B-4E, the valve plate fixing member 440 includes a female threaded hole, and the extension 411 includes a male thread, and the extension 411 passes through the wall of the valve body 420 and threads into the female threaded hole of the valve plate fixing member 440.

[0078] According to some embodiments of the present invention, the torsion portion 430 and the valve plate 410 are connected to each other in a torsion-resistant manner. In some embodiments, the valve plate 410 and the torsion portion 430 are integrally formed, as shown in Figures 4C-4E. However, the present invention is not limited thereto. In some embodiments, the valve plate 410 and the torsion portion 430 may be formed separately and then connected to each other. For example, the valve plate 410 and the torsion portion 430 may be connected to each other using adhesive, screws, etc.

[0079] According to one embodiment of the present invention, the airflow regulator 400 can adjust the airflow of the air passage by rotating the valve plate 410. Specifically, a user manually turns the twisting portion 430 to rotate the valve plate 410 relative to the valve body 420, thereby opening or closing the air passage or adjusting the degree of opening of the air passage.

[0080] As described above, the valve plate 410 and the valve plate fixing member 440 are connected to each other by screws. However, the present invention is not limited to this. Other connection modes between the extension portion 411 of the air flow regulator and the valve plate fixing member 440 will be described below with reference to the drawings.

[0083] In some embodiments, the torsion portion 430 has a protruding torsion feature. The protruding torsion feature can be designed to facilitate contact with a user's hand to perform a twisting operation. When the airflow regulator 400 is attached to the custom housing 100, the protruding torsion feature of the torsion portion 430 can protrude from the exterior of the custom housing 100 to facilitate direct manipulation with a user's fingers. FIGS. 7A-7E show perspective views of a torsion portion according to some embodiments of the present invention.

Pivoting cover 510 includes opening 511, and base 520 includes opening 521. Pivoting cover 510 is rotatable relative to base 520. By rotating pivotable cover 510 relative to base 520, opening 511 of pivotable cover 510 and opening 521 of base 520 communicate with each other and with ventilation hole 300, thereby achieving ventilation of the ventilation path. In the exemplary embodiment, as shown in FIGS. 10C to 10E , twisting part 530 is provided so as to at least partially overlap pivotable cover 510 along the axial direction of pivotable cover 510, i.e., to protrude from the upper surface of pivotable cover 510. In the exemplary embodiment, the twisted portion 530 is located at the second opening 300B of the vent 300.

[0090] 10C-10E, the pivotable cover 510 is positioned to at least partially overlap the base 520 along the pivot axis of the pivotable cover 510. In one embodiment, the pivotable cover 510 is positioned closer to the second opening 300B of the vent 300 than the base 520, i.e., the pivotable cover 510 is closer to the external environment when the user wears the in-ear wireless earphone 10. However, the present invention is not limited thereto. In another embodiment, the pivotable cover 510 is positioned farther from the second opening 300B0 of the vent 30 than the base 520, i.e., the pivotable cover 510 is closer to the user's ear canal when the user wears the in-ear wireless earphone 10.

[0091] In an exemplary embodiment, the axis of rotation of the pivotable cover 510 is substantially parallel to the extension direction of the vent hole 300 in the airflow regulator 400. However, the present invention is not limited thereto. In one embodiment, the axis of rotation of the pivotable cover 510 intersects, for example is substantially perpendicular to, the extension direction of the vent hole 300 in the airflow regulator 400. In this case, the airflow regulator 400 can be more easily installed at a middle position of the vent hole 300.

[0092] In one embodiment, as shown in FIGS. 10C to 10E , the pivotable cover 510 includes an annular cavity 512 and a connecting portion 513, and the connecting portion 513 is disposed within the annular cavity 512. The opening 511 of the pivotable cover 510 is formed by being surrounded by the annular cavity 512 and the connecting portion 513. The base 520 includes an annular cavity 522 and a connecting portion 523, and the connecting portion 523 is disposed within the annular cavity 522. The opening 521 of the base 520 is formed by being surrounded by the annular cavity 522 and the connecting portion 523. The pivotable cover 510 and the base 520 are disposed within the vent hole 300 by the annular cavities 512 and 522, respectively. It should be understood that the present invention does not particularly limit the number of openings and connecting portions of the pivotable cover and the base.

[0093] 10C , the airflow regulator 400 further includes a pivotable cover fastening member 540 and a pin shaft 550 disposed at one end of the base 520 remote from the twisting portion 530. The base 520 has a through-hole. The pin shaft 550 passes through the base 520 and is connected to the pivotable cover 510 and the pivotable cover fastening member 540 to securely restrain the pivotable cover 510. In the exemplary embodiment, the pin shaft 550 is fixedly connected to the pivotable cover fastening member 540. In one embodiment, the pin shaft 550 has a male thread (as shown in FIG. 10C ), the pivotable cover 510 has a female threaded hole (not shown), and the pin shaft 550 passes through the base 520 and is threaded into the female threaded hole of the pivotable cover 510 to connect the pivotable cover 510 and the pivotable cover fastening member 540 to each other.

[0094] According to one embodiment of the present invention, the pin shaft 550 and the pivoting cover fastening member 540 are connected to each other in a torsion-resistant manner. In one embodiment, as shown in FIG. 10C, the pin shaft 550 and the pivoting cover fastening member 540 are integrally formed. In another embodiment, the pin shaft 550 and the pivoting cover fastening member 540 may be formed separately and then connected to each other. For example, the pin shaft 550 and the pivoting cover fastening member 540 may be connected to each other using adhesive, screws, etc.

[0095] According to one embodiment of the present invention, the twisting portion 530 and the pivoting cover 510 are connected to each other in a twist-resistant manner. In one embodiment, as shown in FIGS. 10C to 10E, the twisting portion 530 is integrally formed with the pivoting cover 510. However, the present invention is not limited thereto. In another embodiment, the twisting portion 530 and the pivoting cover 510 may be formed separately and then connected together. For example, the twisting portion 530 and the pivoting cover 510 may be connected to each other using adhesive, screws, etc.

[0096] According to one embodiment of the present invention, airflow regulator 400 can adjust the airflow rate of the air passage by rotating pivotable cover 510 relative to base 520. Specifically, a user manually turns twisting portion 530 to rotate pivotable cover 510 relative to base 520 to open or close the air passage or adjust the degree to which the air passage is open.

[0097] In some embodiments, the torsion portion 530 has a protruding torsion feature. The protruding torsion feature can be designed to facilitate contact with a user's hand to perform a twisting operation. When the airflow regulator 400 is attached to the custom housing 100, the protruding torsion feature of the torsion portion 530 can protrude from the outer surface of the custom housing 100 to facilitate direct manipulation by a user's fingers. The protruding torsion feature of the torsion portion 530 can be shaped like a three-pronged star, a square, a square, a concave, or a strip (as shown in FIGS. 10C-10E), as long as it facilitates direct manipulation by a finger. The shape and structure of the protruding torsion feature can be as described above with reference to FIGS. 7A-7E, and will not be described again here.

[0098] 10A to 10E, an airflow regulator 400 having an open-rotating lid structure according to an embodiment of the present invention has been described. However, those skilled in the art will understand that the open-rotating lid structure of the present invention is not limited to this. Hereinafter, an airflow regulator having an open-rotating lid structure according to an embodiment of the present invention will be described with reference to the drawings.

Figure 11B is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention. Figure 11C is a schematic view of an airflow adjustment device in an open position according to an embodiment of the present invention. Figure 11D is a schematic view of an airflow adjustment device in a closed position according to an embodiment of the present invention.

[0100] As shown in FIG. 11A, the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. The air vent 300 of the in-ear wireless earphone 10 is located within the custom housing 100 and includes a mounting location 300C for mounting an airflow regulator 400 (not shown in FIG. 11A). In the exemplary embodiment, as shown in FIG. 11A, the mounting location 300C is located at the second opening of the air vent 300. In the embodiment shown in FIGS. 11A to 11D, the other components and configurations of the in-ear wireless earphone 10 are as described above, and therefore will not be described again here.

[0101] 11B to 11D, airflow rate regulator 400 includes pivotable cover 510 as a movable part, base 520 as a fixed part, and twisting part 530 as an operating part. Pivoting cover 510 includes opening 511, and base 520 includes opening 521. Pivoting cover 510 is rotatable relative to base 520. By rotating pivotable cover 510 relative to base 520, opening 511 of pivotable cover 510 and opening 521 of base 520 communicate with ventilation hole 300, thereby achieving ventilation of the ventilation path.

[0102] 10A-10E, the pivotable cover 510 has an annular cavity 512, and the base 520 has an annular cavity 522. However, the present invention is not limited thereto. In some embodiments, the pivotable cover 510 and / or the base 520 may not have an annular cavity. Unlike the embodiment shown in FIGS. 10A-10E, the pivotable cover 510 and the base 520 do not have an annular cavity in the embodiment shown in FIGS. 11A-11D.

[0103] 11B to 11D, pivotable cover 510 has connecting portion 513, and base 520 has connecting portion 523. Pivoting cover 510 and base 520 are respectively attached to vent hole 300 via connecting portions 513, 523. As a result, opening 511 of pivotable cover 510 is formed by being surrounded by adjacent connecting portion 513 and the inner wall of vent hole 300, and opening 521 of base 520 is formed by being surrounded by adjacent connecting portion 523 and the inner wall of vent hole 300.

[0104] 11A, the air vent 300 includes a locking groove for receiving the connecting portion 523 of the base 520. When the base 520 of the air flow regulator 400 is installed in the air vent 300, at least a portion of the connecting portion 523 of the base 520 is positioned in the corresponding locking groove. This allows the base 520 to be more firmly installed in the air vent 300, preventing the base 520 from rotating and facilitating manual rotation of the pivotable cover 510 relative to the base 520.

[0105] In the embodiment shown in FIGS. 11A to 11D, the other configuration of the airflow regulator 400 is as described above, and a description thereof will be omitted here.

[0106] 12A, 12B, and 12C are schematic diagrams of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention, respectively, in an exploded view, an open view, and a closed view, respectively, of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention. In one embodiment, as shown in FIGS. 10C to 11C, the twisted portion 530 protrudes from the upper surface of the pivotable lid 510. However, the present invention is not limited to this. In one embodiment, as shown in FIGS. 12A to 12C, the pivotable lid 510 itself serves as the twisted portion 530. For example, the upper surface of the airflow rate regulator 400 is formed as a flat surface. This simplifies the configuration of the airflow rate regulator 400 and reduces the manufacturing cost of the airflow rate regulator 400. In the embodiment shown in FIGS. 12A to 12C, the other configuration of the airflow rate regulator 400 is as described above, and therefore a description thereof will be omitted here.

[0107] 13A, 13B, and 13C are exploded and closed views of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention.

[0108] According to one embodiment of the present invention, as shown in FIGS. 13A to 13C , airflow regulator 400 includes pivotable cover 510 as a movable part, base 520 as a fixed part, and twisting part 530 as an operating part. Pivot cover 510 includes opening 511, and base 520 includes opening 521. Pivot cover 510 is rotatable relative to base 520. By rotating pivotable cover 510 relative to base 520, opening 511 of pivotable cover 510 and opening 521 of base 520 communicate with each other and with vent 300, thereby achieving ventilation of the air passage. In one embodiment, airflow regulator 400 may be attached to second opening 300B of vent 300 (as shown in FIG. 10B ). In one embodiment, the airflow regulator 400 may be attached to the vent 300 at a position away from both the first opening 300A and the second opening 300B, i.e., at a middle position of the vent 300.

[0109] In one embodiment, as shown in FIGS. 13A to 13C , the pivotable cover 510 includes an annular cavity 512 and a connecting portion 513, and the connecting portion 513 is disposed within the annular cavity 512. The opening 511 of the pivotable cover 510 is formed by being surrounded by the annular cavity 512 and the connecting portion 513. The base 520 includes an annular cavity 522 and a connecting portion 523, and the connecting portion 523 is disposed within the annular cavity 522. The opening 521 of the base 520 is formed by being surrounded by the annular cavity 522 and the connecting portion 523. The base 520 is disposed within the ventilation hole 300 by the annular cavity 522.

[0110] In one embodiment, as shown in FIGS. 10C to 11C , the twisting portion 530 is positioned so as to at least partially overlap the pivotable cover 510 along the axial direction of the pivotable cover 510, for example, the twisting portion 530 protrudes from the top surface of the pivotable cover 510. However, the present invention is not limited thereto. In one embodiment, as shown in FIGS. 13A to 13C , the twisting portion 530 is positioned radially outward of the pivotable cover 510. In an exemplary embodiment, the twisting portion 530 and the pivotable cover 510 do not overlap along the axial direction of the pivotable cover 510. Because the twisting portion 530 is positioned radially outward of the pivotable cover 510, the user's fingers can rotate the cover 510 in the circumferential direction, thereby allowing the airflow regulator 400 to be easily positioned at a central position of the air vent 300.

[0111] In some embodiments, as shown in Figures 13A-13C, twisting portion 530 may be configured with a toothed structure to facilitate rotation by a user's finger. In some embodiments, as shown in Figures 13A-13C, base 520 may have a recess 524. Recess 524 allows at least a portion of twisting portion 530 to protrude relative to base 520 to facilitate rotation by a user's finger.

[0112] In the embodiment shown in FIGS. 13A to 13C, the other configuration of the airflow regulator 400 is as described above, and a description thereof will be omitted here.

[0113] In the above description, the pin shaft 550 is first fixedly connected to (e.g., integrally formed with) the pivot cover fixing member 540, and then the pin shaft 550 is connected to the pivot cover 510. However, the present invention is not limited to this. In some embodiments, the pin shaft 550 may first be fixedly connected to (e.g., integrally formed with) the pivot cover 510, and then connected to the pivot cover fixing member 540. For example, the pin shaft 550 and the pivot cover 510 may be connected to each other by adhesive, screws, etc., or may be integrally formed. For specific connection methods, please refer to the descriptions with reference to Figures 4C to 6C and 8A to 9C above, and further description will be omitted here.

[0114] Although the torsion portion 530 is described above as having a protruding torsion feature that facilitates direct finger manipulation, the present invention is not limited thereto. In some embodiments, the torsion portion 530 has a recessed torsion feature. In some embodiments, when the airflow regulator 400 is attached to the custom housing 100, the recessed torsion feature of the torsion portion 530 does not protrude from the exterior surface of the custom housing 100, and therefore the recessed torsion feature must be twisted by an external torsion member (e.g., a dedicated torsion adjustment rod, etc.). The shape and structure of the recessed torsion feature may refer to the description above with reference to Figures 8A-9C, and will not be described again here.

[0115] In the above description, the rotation axis of the pivotable lid 510 is substantially parallel to the extension direction of the air vent 300 in the airflow regulator 400, and / or the extension direction of the portion of the air vent 300 at the mounting position 300C is substantially linear. However, the present invention is not limited to this. Hereinafter, an airflow regulator having an open pivotable lid structure according to an embodiment of the present invention will be described with reference to the drawings.

[0116] Figure 14A is a perspective view of an in-ear wireless earphone according to an embodiment of the present invention. Figure 14B is a cross-sectional schematic view of an in-ear wireless earphone according to an embodiment of the present invention. Figure 14C is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to an embodiment of the present invention. Figure 14D is a cross-sectional schematic view of an airflow adjustment device in an open position according to an embodiment of the present invention.

[0117] As shown in Figure 14A, the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. As shown in Figure 14B, the air vent 300 of the in-ear wireless earphone 10 is provided in the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400. In the exemplary embodiment, as shown in Figure 14B, the mounting location 300C is provided at the second opening 300B of the air vent 300. In the embodiment shown in Figures 14A to 14E, the other components and configurations of the in-ear wireless earphone 10 are as described above, and therefore will not be described again here.

[0118] According to one embodiment of the present invention, as shown in FIGS. 14C to 14E , airflow regulator 400 includes pivotable cover 510 as a movable part, base 520 as a fixed part, and twisting part 530 as an operating part. Pivoting cover 510 includes opening 511, and base 520 includes opening 521. Pivoting cover 510 is rotatable relative to base 520. By rotating pivotable cover 510 relative to base 520, opening 511 of pivotable cover 510 and opening 521 of base 520 communicate with each other and with ventilation hole 300, thereby achieving ventilation of the ventilation path. In the exemplary embodiment, as shown in FIGS. 14C to 14E , twisting part 530 is provided so as to at least partially overlap pivotable cover 510 along the axial direction of pivotable cover 510, i.e., to protrude from the upper surface of pivotable cover 510. In the exemplary embodiment, twist 530 is located in the second portion of custom housing 100 at a location other than second aperture 300B.

[0119] 10A to 13C, it has been described above that the rotating cover 510 includes a connecting portion 513, and at least a portion of the opening 511 of the rotating portion 510 is surrounded by the connecting portion 513, and / or the base 520 includes a connecting portion 523, and at least a portion of the opening 521 of the base 520 is surrounded by the connecting portion 523. However, the present invention is not limited thereto. In some embodiments, the rotating cover 510 and / or the base 520 may not include a connecting portion. Unlike the embodiment shown in FIGS. 10A to 13C, the rotating cover 510 and the base 520 do not include a connecting portion in the embodiment shown in FIGS. 14A to 14E.

[0120] 14C to 14E , the pivotable cover 510 includes an annular cavity 512, and the base 520 includes an annular cavity 522. In an exemplary embodiment, the annular cavity 512 of the pivotable cover 510 is disposed within, i.e., surrounded by, the annular cavity 522 of the base 520 along the rotation axis of the pivotable cover 510. This allows the pivotable cover 510 and the base 520 to be disposed within the vent hole 300 by the annular cavity 522. In an exemplary embodiment, the opening 511 of the pivotable cover 510 is formed in the annular cavity 512, and the opening 521 of the base 520 is formed in the annular cavity 522.

[0121] 10A to 13C, the extension direction of the ventilation hole 300 at the attachment position 300C is not a substantially straight line but has a bent or curved shape, for example, a bent line shape exhibiting an angle of 90 degrees. As a result, the ventilation hole 300 has a bent segment at least at the attachment position 300.

[0122] According to one embodiment of the present invention, the airflow regulator 400 can adjust the airflow rate of the air passage by rotating the pivotable cover 510 relative to the base 520. Specifically, a user rotates the pivotable cover 510 relative to the base 520 by manually twisting the twisting portion 530. The air passage can be opened or closed by overlapping or separating the opening 511 of the pivotable cover 510 and the opening 521 of the base 520 with each other, or the degree to which the opening of the air passage is open can be adjusted by adjusting the degree to which the opening 511 of the pivotable cover 510 and the opening 521 of the base 520 overlap with each other.

[0123] In the embodiment shown in FIGS. 14A to 14E, the other configuration of the airflow regulator 400 is as described above, and a description thereof will be omitted here.

[0124] Check valve structure According to some embodiments of the present invention, the airflow adjustment device can employ a check valve structure. Fig. 15A is a perspective view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 15B is a cross-sectional schematic view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 15C is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 15D is a cross-sectional schematic view of an airflow adjustment device in an open state according to some embodiments of the present invention. Fig. 15E is a cross-sectional schematic view of an airflow adjustment device in a closed state according to some embodiments of the present invention.

[0125] As shown in FIG. 15A, the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. As shown in FIG. 15B, the air vent 300 of the in-ear wireless earphone 10 is located on the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400. In an exemplary embodiment, as shown in FIG. 15B, the mounting location 300C is located at the second opening 300B of the air vent 300. In one embodiment, the mounting location 300C is located away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a midpoint of the air vent 300. The other components and configuration of the in-ear wireless earphone 10 are as described above, and will not be described again here.

[0126] According to one embodiment of the present invention, as shown in Figures 15C to 15E, airflow regulator 400 includes valve core 610 as a movable part, valve seat 620 as a fixed part, and pressing part 630 as an operating part. Valve seat 620 includes fluid passage 621 that communicates with the vent hole. Valve core 610 can open and close fluid passage 621 by moving relative to valve seat 620. In the exemplary embodiment, pressing part 630 is provided at second opening 300B of vent hole 300.

[0127] According to one embodiment of the present invention, the airflow regulator 400 can adjust the airflow rate of the air passage by moving the valve core 610 relative to the valve seat 620. Specifically, a user manually presses the pressing portion 630 to move the valve core 610 relative to the valve seat 620, thereby opening or closing the air passage or adjusting the degree of opening of the air passage.

[0128] 15C to 15E, the airflow regulator 400 further includes a spring 640. The spring 640 is configured to apply an elastic force to the valve core 610. When a user applies a pressing force to the pressing portion 630, the pressing force of the user is transmitted to the valve core 610 and resists the elastic force of the spring 640, causing the valve core 610 to move closer to or farther away from the valve seat 620, thereby closing or opening the fluid passage 621.

[0129] 15C to 15E, the airflow regulator 400 further includes a sleeve 650. The sleeve 650 has a slide path 651. When a user applies a pressing force to the pressing portion 630, the pressing portion 630 can move along the slide path 651.

[0130] In one embodiment, as shown in FIGS. 15C to 15E , the pressing portion 630 further includes an upper pressing rod 631 and a lower pressing rod 632. The upper pressing rod 631 is configured to be pressed by a user. The upper pressing rod 631 and the lower pressing rod 632 are movably connected and have a form-fitting structure. Through the cooperation of the upper pressing rod 631, the lower pressing rod 632, the spring 640, and the sleeve 650, the valve core 610 may be locked in a state in which the fluid passage 621 is opened or closed after the user presses the pressing portion 630, and may be locked in another state in which the fluid passage 621 is opened or closed after the user presses the pressing portion 630 again. In one embodiment, as shown in FIGS. 15C to 15E , the pressing portion 630 includes a ventilation groove 633 for ventilation with the external environment.

[0131] 15A-15E, the direction of movement of the valve core 610 and the direction of movement of the pressing portion 630 are substantially parallel to the direction of extension of the air vent 300 in the air flow regulator 400. However, the present invention is not limited to this. In some embodiments, the direction of movement of the valve core 610 and the direction of movement of the pressing portion 630 intersect, for example, are substantially perpendicular to, the direction of extension of the air vent 300 in the air flow regulator 400. In this case, the air flow regulator 400 can be easily installed at a midpoint of the air vent 300.

[0132] Aperture structure According to some embodiments of the present invention, the airflow adjustment device can have a restrictor structure. Fig. 16A is a perspective view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 16B is a schematic cross-sectional view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 16C is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 16D is a schematic view of an airflow adjustment device in an open position according to some embodiments of the present invention. Fig. 16E is a schematic view of an airflow adjustment device in a closed position according to some embodiments of the present invention.

[0133] As shown in FIG. 16A , the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. As shown in FIG. 16B , the air vent 300 of the in-ear wireless earphone 10 is disposed within the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400. In an exemplary embodiment, as shown in FIG. 16B , the mounting location 300C is located at the second opening 300B of the air vent 300. In some embodiments, the airflow adjustment device 400 may be mounted at a location away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a midpoint of the air vent 300. In the embodiments shown in FIGS. 16A to 16E , the other components and configurations of the in-ear wireless earphone 10 are as described above, and therefore will not be described again here.

[0134] According to one embodiment of the present invention, as shown in FIGS. 16C to 16E , the airflow regulator 400 includes a plurality of vanes 710 as a movable part, a fixed base 720 as a fixed part, and a rotating wheel 730 as an operating part. The fixed base 720 includes a fluid passage 721 communicating with the air vent 300. The rotating wheel 730 can drive the vanes 710 to move relative to the fixed base 720. The rotating wheel 730 is rotatable relative to the fixed base 720. By rotating the rotating wheel 730 relative to the fixed base 720, the vanes 710 can be coupled to each other to close the fluid passage 721 of the fixed base 720, or separated from each other to open the fluid passage 721 of the fixed base 720, thereby adjusting the airflow rate of the air passage. In the exemplary embodiment, the rotating wheel 730 is installed at the second opening 300B of the air vent 300. In one embodiment, the wheel 730 is located in the second portion of the custom housing 100 at a location other than the second aperture 300B.

[0135] 16C to 16E, in an exemplary embodiment, blade 710 has a first protrusion 711 protruding from one surface and a second protrusion 712 protruding from the other surface, rotating wheel 730 has a driving groove 731 that fits with first protrusion 711, and fixed base 720 has a sliding groove 722 that fits with second protrusion 712. When rotating wheel 730 rotates relative to fixed base 720, first protrusion 711 of blade 710 moves in driving groove 731, and second protrusion 712 moves in sliding groove 722.

[0136] In an exemplary embodiment, the axis of rotation of the rotating wheel 730 and the extension direction of the air vent 300 in the air vent regulator 400 are substantially parallel. However, the present invention is not limited thereto. In some embodiments, the axis of rotation of the rotating wheel 730 and the extension direction of the air vent 300 in the air vent regulator 400 intersect, for example, are substantially perpendicular. In this case, the air vent regulator 400 can be easily installed at a midpoint of the air vent 300.

[0137] According to one embodiment of the present invention, the airflow regulator 400 can adjust the airflow of the air passage by rotating the rotating wheel 730 relative to the fixed base 720 to move the blades 710 relative to the fixed base 720. Specifically, a user manually turns the rotating wheel 730 to move the blades 710 relative to the fixed base 720, thereby opening or closing the air passage or adjusting the degree of opening of the air passage.

[0138] Plug-in structure According to some embodiments of the present invention, the airflow adjustment device may adopt a plug-type structure. Fig. 17A is a perspective view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 17B is a schematic cross-sectional view of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 17C is an exploded schematic view of an airflow adjustment device of an in-ear wireless earphone according to some embodiments of the present invention. Fig. 17D is a schematic cross-sectional view of an airflow adjustment device in a closed state according to some embodiments of the present invention. Fig. 17E is a schematic cross-sectional view of an airflow adjustment device in an open state according to some embodiments of the present invention. Fig. 17F is a schematic cross-sectional view of an airflow adjustment device in an open state according to some embodiments of the present invention.

[0139] As shown in FIG. 17A, the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. As shown in FIG. 17B, the air vent 300 of the in-ear wireless earphone 10 is disposed within the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400. In an exemplary embodiment, as shown in FIG. 17B, the mounting location 300C is located at the second opening 300B of the air vent 300. In some embodiments, the airflow adjustment device 400 may be mounted at a location away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a midpoint of the air vent 300. In the embodiments shown in FIGS. 17A to 17F, the other components and configurations of the in-ear wireless earphone 10 are as described above, and therefore will not be described again here.

[0140] According to one embodiment of the present invention, as shown in FIGS. 17C to 17F , airflow regulator 400 includes plug 810 as a movable and operating part, and mounting seat 820 as a fixed part. Mounting seat 820 includes fluid passage 821 that communicates with vent hole 300. Mounting seat 820 is fixed to vent hole 300. In the exemplary embodiment, mounting seat 820 is a separate mounting seat, i.e., formed separately from custom housing 100. Plug 810 can be inserted into and removed from mounting seat 820. By inserting and removing plug 810, ventilation of the air passage can be achieved, or the degree of opening of the air passage can be adjusted.

[0141] 17C-17F, the plug 810 includes a fluid passage 811. The fluid passage 811 of the plug 810 can be used to communicate between the fluid passage 821 of the mounting seat 820 and the external environment. When the plug 810 is inserted into the mounting seat 820, the fluid passage 811 of the plug 810 is in fluid communication with the fluid passage 821 of the mounting seat 820.

[0142] 17D-17F, when achieving ventilation of the ventilation path, plug 810 does not need to be completely withdrawn from mounting seat 820, but may be partially withdrawn. This allows plug 810 to be held at different positions relative to mounting seat 820 while being gradually withdrawn from mounting seat 820, thereby achieving various degrees of ventilation. In one embodiment, as shown in FIGS. 17D-17F, plug 810 includes a position restricting portion 812, and mounting base 820 includes a corresponding position restricting portion 822. This allows plug 810 to be restricted to different positions relative to mounting seat 820 by the engagement of position restricting portions 812 and 822, making it easier to achieve various degrees of ventilation. In the above, the air vent regulator 400 having a pluggable structure according to one embodiment of the present invention has been described as including a separate mounting seat 820. However, those skilled in the art will understand that the pluggable structure of the present invention is not limited to this. Hereinafter, an air vent regulator having a pluggable structure according to one embodiment of the present invention will be described with reference to the drawings.

[0144] As shown in FIG. 18A , the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and an air vent 300. The air vent 300 of the in-ear wireless earphone 10 is located within the custom housing 100 and includes a mounting location 300C for mounting an airflow adjustment device 400. In an exemplary embodiment, as shown in FIG. 18A , the mounting location 300C is located at the second opening 300B of the air vent 300. In some embodiments, the airflow adjustment device 400 may be mounted at a location away from both the first opening 300A and the second opening 300B of the air vent 300, i.e., at a midpoint of the air vent 300. In the embodiments shown in FIGS. 18A to 18C , the other components and configurations of the in-ear wireless earphone 10 are as described above, and therefore will not be described again here.

[0145] According to one embodiment of the present invention, as shown in FIGS. 18A-18C, the airflow regulator 400 includes a plug 810 as a movable part and an operating part. As described above with reference to FIGS. 17A-17F, the airflow regulator 400 is described as including a separate mounting seat. However, the present invention is not limited thereto. In one embodiment, the mounting seat can be formed on the custom housing 100. Unlike the embodiment shown in FIGS. 17A-17F, in the embodiment shown in FIGS. 18A-18C, the mounting seat 820 is formed on the custom housing 100. In an exemplary embodiment, the mounting seat 820 and the custom housing 100 are integrally formed. The plug 810 can be inserted into and removed from the mounting seat 820. By inserting and removing the plug 810, ventilation of the air passage can be achieved, or the degree of opening of the air passage can be adjusted.
