[0002] With the increasing application of mobile devices such as smartphones, and people's increasing use of audio and video services, wireless headphones have quickly become popular due to their advantages such as portability and the absence of entanglement problems. TWS (true wireless stereo) Bluetooth headphones have become the mainstream product among wireless headphones due to their advantages such as short latency and good sound quality. However, most of the current TWS Bluetooth headphones are standard-sized headphones, which can cause discomfort in the ears of the wearer if worn for a long time, thus limiting the wearing time and application scenarios. In addition, if an in-ear wearable device is worn for a long time, the external auditory canal will be blocked, resulting in an ear-blocking effect, an imbalance in pressure inside and outside the ear, and reduced comfort. It may also cause moisture infection due to the lack of ventilation in the ear canal.

[0114] 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 illustrate the principles of the present invention by way of example. The present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims. The present invention will now be described in detail with reference to exemplary embodiments, some of which 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.

[0115] 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 ear 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 using an in-ear wireless headset 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 headsets. For example, in addition to the audio reproduction function, the in-ear wearable device can be additionally or alternatively implemented to have functions such as sound reception, temperature detection, blood pressure detection, heart rate detection, blood sugar detection, blood oxygen detection, etc. In addition, in some embodiments, the in-ear wearable device may not be implemented as an in-ear wireless headset, that is, it does not have an audio reproduction function, but only has other functions.

[0116] Figure 1 is a perspective view of an in-ear wireless headset 10 according to some embodiments of the present invention. Figure 1 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 earphones, left and right, 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. The in-ear wireless earphone 10 includes a first side 10A and a second side 10B. The first side 10A of the in-ear wireless earphone 10 represents the side located in the user's ear canal when the user wears the in-ear wireless earphone 10, and the second side 10B of the in-ear wireless earphone 10 represents the side exposed to the external environment when the user wears the in-ear wireless earphone 10. As Figure 1 As shown, the first side 10A of the in-ear wireless headset 10 is located at the lower portion, and the second side 10B is located at the upper portion.

[0117] refer to Figure 1 According to some embodiments of the present invention, an in-ear wireless headset 10 includes a customized housing 100 and a panel 200 . Figure 2 is a stereoscopic view of a customized shell of an in-ear wireless headset according to certain embodiments of the present invention. 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. The customized shell 100 can be, for example, made by taking an ear mold from the user's ear and then using manufacturing equipment to manufacture it based on the taken ear mold. The customized shell 100 can be manufactured by 3D printing or by other manufacturing methods. The size of the customized shell 100 can be the same as the taken ear mold, or it can be slightly smaller than the taken ear mold to improve the wearing comfort of some sensitive users.

[0118] When a user wears a standard pair of headphones, since their dimensions are fixed, they need to be as small as possible to accommodate most users' ear sizes (e.g., the concha cavity). However, to ensure a stable fit and prevent them from falling, they also need to have protrusions to keep the headphones firmly in place on the ear. In this case, standard headphones can compress certain areas of the ear canal or auricle when worn, causing discomfort after prolonged wear. For example, many users experience ear discomfort after wearing standard headphones for 30 minutes or even less. In contrast, the custom housing 100 of the in-ear wireless headphones 10 of the present invention is user-specific and does not cause substantial pressure on the user's ears. Therefore, compared to standard headphones, the in-ear wireless headphones 10 of the present invention offer improved wearing comfort, allowing users to wear the headphones for longer periods of time, for example, for several hours or even longer. Furthermore, since users can wear the headphones for longer periods of time, they are more likely to use them in a variety of scenarios. For example, in addition to conventional audio and video services, they can also be used for making and receiving voice or video calls, playing games, and engaging in various virtual reality activities.

[0119] In an exemplary embodiment, the customized shell 100 has an integral structure or is formed in one piece, that is, it is formed once based on the user's ear mold. In other embodiments, the customized shell 100 may also be composed of multiple parts. For example, the customized shell 100 may include a core part and a customized adapter part, wherein the core part is the same for all users or most users and can be assembled with the panel 200, while the customized adapter part is a part formed based on the user's ear mold. In the case where the customized shell 100 includes the core part and the customized adapter part, since the components other than the customized adapter part are the same for most users, production efficiency can be improved.

[0120] According to certain embodiments of the present invention, the customized housing 100 includes a first portion for inserting into the user's ear canal 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. Through "customization", when the user wears the in-ear wireless headset 10, the customized housing 100 at least partially fits the user's ear canal. Thus, the first portion of the customized housing 100 serves as the portion that fits the user's ear canal, that is, the portion isolated from the external environment, to provide a sealed listening environment in the ear canal when the user wears the in-ear wireless headset 10. In addition, the second portion of the customized housing 100 serves as the portion exposed to the external environment when the user wears the in-ear wireless headset 10, to provide operating space for the ventilation volume adjustment device (described in detail below). In some embodiments, the second portion of the customized housing 100 includes an open end. The open end is located on the side of the second portion away from the first portion. In some embodiments, the panel 200 is mounted to the customized housing 100 at the open end of the second portion of the customized housing 100. For example, other components of the in-ear wireless headset 10 may be arranged in the customized housing 100 through the open end, and then the panel 200 may be mounted to the open end.

[0121] According to certain embodiments of the present invention, the customized housing 100 includes a housing wall 110 and an inner cavity 120 surrounded by the housing wall 110. In some embodiments, the in-ear wireless headset 10 may further include components such as a mainboard, a control device, a charging device, a battery, an antenna device, a magnet, a pickup device, a speaker assembly, a wireless communication module, etc. The various components can be assembled together by bolts, welding, gluing, snapping, etc. These components can be arranged in the space enclosed by the customized housing 100 and the panel 200. Specifically, these components can be mainly located in the inner cavity 120 of the customized housing 100, and the panel 100 can be used to close the inner cavity 120. The panel 200 can be a flat cover plate, or it can be an uneven or other uneven cover plate, as long as the other components can work normally. In an exemplary embodiment, the panel 200 is mounted to the customized housing 100 on the second side 10B of the in-ear wireless headset 10.

[0122] In some embodiments, as Figure 2 As shown, the customized 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 located in the user's cavum concha or the cavum concha and external auditory canal, and the second protrusion 140 may be located in the user's cymba concha. The first protrusion 130 may include an opening, and the speaker assembly is located within the first protrusion 140 near the opening. As a result, sound output by the sound output device of the speaker assembly enters the user's ear canal through the opening.

[0123] Figure 3is a schematic cross-sectional view of an in-ear wireless headset according to some embodiments of the present invention. According to some embodiments of the present invention, the in-ear wireless headset includes a vent 300 and an air volume adjustment device 400. The vent 300 is at least partially disposed in the customized shell 100, that is, at least partially formed by the customized shell 100. In some embodiments, the section of the vent 300 disposed in the customized shell 100 is formed in the shell wall 110. For example, the section of the vent 300 disposed in the customized shell 100 may be formed together when the customized shell 100 is manufactured, or may be additionally formed in the shell wall 110 after the customized shell 100 is manufactured. In some embodiments, the vent has a diameter of 0.8 to 3.0 mm, for example, 2.0 mm. According to some embodiments of the present invention, such as Figure 3 As shown, the vent 300 is completely disposed in the customized shell 100. In an exemplary embodiment, the vent 300 is completely disposed in the shell wall 110 of the customized shell 100. The vent 300 includes a first opening 300A exposed to the user's ear canal when the user wears the in-ear wireless headset 10 and a second opening 300B exposed to the external environment. Thus, the first opening 300A is located on the first side 10A of the in-ear wireless headset 10, and the second opening 300B is located on the second side 10B of the in-ear wireless headset 10. In some embodiments, the vent 300 is a straight-through vent. In some embodiments, the vent 300 is a bent vent. Compared with a straight-through vent, a bent vent can provide a longer vent length in a relatively small volume, thereby being more suitable for in-ear wireless headsets 10 or customized shells 100 of smaller volumes.

[0124] According to certain embodiments of the present invention, an air volume adjustment device 400 is installed in the vent 300. The vent 300 and the air volume adjustment device 400 at least partially constitute a ventilation channel that is isolated from the inner cavity 120 of the custom shell 100. In this article, "isolation" means that when the user wears the in-ear wireless headset 10 (i.e., when the first part of the custom shell 100 is inserted into the user's ear canal), the ventilation channel is not in fluid communication with the inner cavity 120 of the custom shell 100. The ventilation channel is configured to enable fluid communication between the user's ear canal and the external environment when the user wears the in-ear wireless headset 10. Thus, the ventilation channel is configured to enable fluid communication between the first side 10A and the second side 10B of the in-ear wireless headset. By isolating the ventilation channel from the inner cavity 120 of the custom shell 100, the impact of the ventilation airflow on the internal components and sound quality of the in-ear wireless headset can be avoided or reduced during ventilation of the ventilation channel, thereby improving the applicability and stability of the in-ear wireless headset in different modes.

[0125] In some embodiments, the ventilation volume adjustment device 400 is disposed at the second opening 300B of the vent 300, that is, at the end of the vent 300 on the second side 10B. In some embodiments, the ventilation volume adjustment device 400 is disposed in the vent 300 at a position spaced apart from both the first opening 300A and the second opening 300B, that is, at the middle of the vent 300.

[0126] According to certain embodiments of the present invention, the vent channel is at least partially disposed within the custom housing 100. In some embodiments, the vent channel is entirely disposed within the custom housing 100. In some embodiments, the vent channel is a straight-through channel. In some embodiments, the vent channel is a curved channel. The curved channel is suitable for placement in smaller housings and in-ear wireless headphones, allowing for a vent channel of the same length or longer than a straight-through channel.

[0127] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 is configured to be manually operated to adjust the ventilation volume of the ventilation channel. In this context, "manual operation" means operation solely with the force applied by the user's hand, without the aid of electricity. Specifically, the ventilation volume adjustment device 400 can be manually operated to open and close the vent 300, thereby opening and closing the ventilation channel. This allows the ventilation channel to be ventilated when the ventilation volume adjustment device 400 is open, and provides a better listening experience when the ventilation volume adjustment device 400 is closed.

[0128] When a user wears an in-ear wireless headset with a customized shell, the ear canal is sealed by the customized shell when the vent is closed, so that the user can have a better listening experience, such as music. However, when the vent is closed, due to the ear occlusion effect, the ear canal is sealed by the customized 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 vent 300 through the ventilation volume adjustment device 400, different usage modes can be switched to overcome the ear occlusion effect, improve the user's wearing comfort, and adapt to different usage scenarios.

[0129] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 can be manually switched between a fully open state for fully opening (100%) the ventilation channel and a fully closed state for fully closing (0%) the ventilation channel. In the fully open state, the ventilation channel is in a maximum open state, thereby achieving maximum ventilation. In the fully closed state, the ventilation channel is in a completely closed state, thereby preventing ventilation.

[0130] In some embodiments, in addition to the fully open and fully closed states described above, the ventilation volume adjustment device 400 can also be manually operated to be in one or more partially open states for partially opening the ventilation channel. Thus, the ventilation volume adjustment device 400 can have multiple ventilation volume levels. For example, the ventilation volume adjustment device 400 can be manually operated to be in a 25% open state, a 50% open state, a 75% open state, and so on.

[0131] In some embodiments, the ventilation volume adjustment device 400 can also be manually operated to continuously adjust the ventilation volume of the ventilation channel. In this way, the ventilation volume adjustment device 400 can be infinitely adjusted.

[0132] In some embodiments, the ventilation volume adjustment device 400 is configured to adjust the audio characteristics of the in-ear wireless headset 10 by adjusting the ventilation volume of the ventilation channel. Thus, the ventilation volume adjustment device 400 can adjust the ventilation volume of the ventilation channel, that is, the degree of opening of the vent. When the ventilation channel of the in-ear wireless headset 10 is completely closed, the in-ear wireless headset 10 can have a better noise reduction effect and audio listening experience. When the user operates the ventilation volume adjustment device 400 to open the ventilation channel of the in-ear wireless headset 10, the ventilation channel can be ventilated, so that the user can receive the external environment sound more clearly, avoid the ear blocking effect, and improve wearing comfort. In addition, when the user operates the ventilation volume adjustment device 400 to make the ventilation channel have different ventilation volumes, the in-ear wireless headset 10 will have different audio characteristics, so that the user can easily adjust his or her listening experience to meet different needs.

[0133] In some embodiments, the ventilation volume adjustment device 400 can be installed at the first opening 300A or the second opening 300B of the vent 300. In some embodiments, the ventilation volume adjustment device 400 is installed at a position in the vent 300 that is spaced apart from both the first opening 300A and the second opening 300B, i.e., in the middle of the vent 300. By installing the ventilation volume adjustment device 400 at different positions in the vent, different in-ear wireless headphones 10 can have different audio cavities, thereby defining different audio effects to meet personalized needs.

[0134] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 includes an operating portion located on the second portion of the customized shell 100 and exposed from the outer surface of the customized shell 100. The user can manually operate the operating portion of the ventilation volume adjustment device 400 to adjust the ventilation volume of the ventilation channel. By exposing the operating portion of the ventilation volume adjustment device 400 to the external environment when the user wears the in-ear wireless headset 10, the user does not need to remove the in-ear wireless headset 10, but can directly operate the ventilation volume adjustment device 400 while wearing it to adjust the ventilation volume of the ventilation channel. As a result, the user's operation can be more convenient and the user experience is improved.

[0135] In some embodiments, the operating portion of the ventilation volume adjustment device 400 is provided at the second orifice 300B of the vent 300. By arranging the operating portion and the second orifice (outlet) of the vent 300 together, the space occupied by the ventilation volume adjustment device 400 on the outer surface of the in-ear wireless headset 10 can be reduced, which is conducive to achieving a more compact structure and reducing the manufacturing and assembly costs of the in-ear wireless headset 10. In some embodiments, the operating portion of the ventilation volume adjustment device 400 is provided on the second part of the customized shell 100 and is located at a position other than the second orifice 300B. Thus, the operating portion of the ventilation volume adjustment device 400 is not located at the second orifice 300B. By arranging the operating portion and the second orifice of the vent 300 separately, the influence of the user's operating action on the airflow at the second orifice can be reduced, so that the user can more accurately perceive the influence of the adjustment of the ventilation volume adjustment device 400 on the audio characteristics.

[0136] According to some embodiments of the present invention, the ventilation volume regulating device 400 further includes a movable portion and a fixed portion, wherein the movable portion can move relative to the fixed portion to adjust the ventilation volume of the ventilation channel. The ventilation volume regulating device according to some embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Figures 4C to 4E As shown, the valve plate 410 and the screwing portion 430 are integrally formed. However, the present invention is not limited thereto. In some embodiments, the valve plate 410 and the screwing portion 430 may be formed separately and connected together. For example, the valve plate 410 and the screwing portion 430 may be connected to each other by an adhesive, threads, etc.

[0144] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 can adjust the ventilation volume of the ventilation channel by rotating the valve plate 410. Specifically, a user manually rotates the screw portion 430, thereby rotating the valve plate 410 relative to the valve body 420, thereby opening or closing the ventilation channel or adjusting the degree of opening of the ventilation channel.

[0145] The valve plate 410 and the valve plate fixing member 440 are described above as being coupled to each other via threads. However, the present invention is not limited thereto.

In an exemplary embodiment, the screwing portion 530 is provided at the second opening 300B of the vent hole 300.

[0156] In some embodiments, as Figures 10C to 10E As shown, the rotating cover 510 is arranged to at least partially overlap with the base 520 along the rotation axis of the rotating cover 510. In some embodiments, the rotating cover 510 is arranged closer to the second opening 300B of the vent 300 relative to the base 520, that is, when the user wears the in-ear wireless headset 10, the rotating cover 510 is closer to the external environment. However, the present invention is not limited to this. In other embodiments, the rotating cover 510 is arranged farther away from the second opening 300B of the vent 300 relative to the base 520, that is, when the user wears the in-ear wireless headset 10, the rotating cover 510 is closer to the user's ear canal.

[0157] In an exemplary embodiment, the rotation axis of the rotating cover 510 is substantially parallel to the direction in which the vent hole 300 extends at the ventilation volume adjustment device 400.

The opening 521 of the base 520 is formed by being surrounded by the annular cavity 522 and the connecting portion 523. The rotating cover 510 and the base 520 are respectively arranged in the vent 300 through the annular cavities 512 and 522. It should be understood that the present invention does not specifically limit the number of openings and connecting portions of the rotating cover and the base.

[0159] In some embodiments, as Figure 10C As shown, the ventilation volume regulating device 400 further includes a rotating cover fixing member 540 and a pin 550 disposed at an end of the base 520 away from the screwing portion 530. The base 520 includes a through hole. The pin 550 passes through the base 520 and connects the rotating cover 510 and the rotating cover fixing member 540 to fix and constrain the rotating cover 510. In an exemplary embodiment, the pin 550 is fixedly connected to the rotating cover fixing member 540. In some embodiments, the pin 550 includes an external thread (such as Figure 10C As shown), the rotating cover 510 includes an internal threaded hole (not shown), and the pin 550 passes through the base 520 to be threadedly engaged with the internal threaded hole of the rotating cover 510, thereby connecting the rotating cover 510 and the rotating cover fixing member 540 to each other.

[0160] According to some embodiments of the present invention, the pin 550 and the rotating cover fixing member 540 are connected to each other in a torsionally non-rotatable manner. Figure 10C As shown, the pin 550 is integrally formed with the rotating cover fixing member 540. In some embodiments, the pin 550 and the rotating cover fixing member 540 can be formed separately and connected together. For example, the pin 550 and the rotating cover fixing member 540 can be connected to each other by an adhesive, a thread, etc.

[0161] According to some embodiments of the present invention, the screwing portion 530 and the rotating cover 510 are connected to each other in a torsionally non-rotatable manner.
