Abstract

This application relates to an in-ear wearable device, including a housing, a first speaker, and a ventilation valve. The housing includes a first mounting portion, a second mounting portion, a third mounting portion, and a fourth mounting portion. When a user wears the in-ear wearable device, the first mounting portion is configured to correspond to the user's external auditory canal, the second mounting portion is configured to correspond to the user's tragus notch, the third mounting portion is configured to correspond to the user's cymba concha, and the fourth mounting portion is configured to correspond to the user's cavum concha. The first speaker is located near the first mounting portion, and the ventilation valve is located in one of the second, third, and fourth mounting portions. The ventilation valve allows or restricts communication between the user's external auditory canal and the external environment. Thus, through the rational arrangement of the first speaker and the ventilation valve, a limited accommodating cavity can simultaneously accommodate both the first speaker and the ventilation valve, solving the problem of ear occlusion, improving the user's comfort when wearing the in-ear wearable device, and also improving sound quality.

Description

Technical Field

[0001] This application relates to the field of wearable device technology, and in particular to an in-ear wearable device. Background Technology

[0002] The occlusion effect is a common problem with in-ear wearable devices. When the ear canal is sealed by the device, the user's voice can travel through the skull into the ear canal. Due to the small volume of the ear canal, low-frequency sound reflections are amplified, creating an "echo" or "hole" sensation. Prolonged use of in-ear devices can cause discomfort and negatively impact the user experience.

[0003] To address the ear occlusion effect, a vent valve is typically incorporated into in-ear wearable devices. This valve regulates the air pressure balance between the ear canal and the external environment, reducing discomfort caused by ear canal blockage. However, determining the optimal placement of the speaker and vent valve to ensure both function effectively remains a challenge. Utility Model Content

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] One embodiment of this application provides an in-ear wearable device, which can be a hearing aid, headphones, or other electronic devices that can be worn on the ear. The shape of the in-ear wearable device is not specifically limited and can be bean-shaped, rod-shaped, or other shapes.

[0053] See Figure 3 The in-ear wearable device includes a housing 10 and a first speaker 20, which is disposed inside the housing 10.

[0054] Specifically, the first loudspeaker 20 is a moving coil unit. The moving coil unit includes a diaphragm, voice coil, magnetic circuit system, and frame, etc. When an audio signal passes through the voice coil, the voice coil moves in the magnetic field, causing the diaphragm to vibrate, thereby pushing the air to produce sound.

[0055] In one embodiment, see Figure 1 , Figure 3 and Figure 21 The outer shell 10 has a receiving cavity 11 and a sound outlet 12 communicating with the receiving cavity 11. The first speaker 20 is disposed in the receiving cavity 11. When the user wears the in-ear wearable device, the sound outlet 12 communicates with the user's external auditory canal, and the sound emitted by the first speaker 20 can be transmitted to the external auditory canal through the sound outlet 12, so that the user can hear the sound.

[0056] Further, see Figure 1 and Figure 21 The outer casing 10 includes a first mounting portion 13. When a user wears the in-ear wearable device, the first mounting portion 13 is positioned corresponding to the user's external auditory canal opening 91. A sound outlet 12 is located on the first mounting portion 13, and a first speaker 20 is positioned close to the first mounting portion 13. When the user uses the in-ear wearable device, the first speaker 20 is positioned at or near the external auditory canal opening 91, thus ensuring the sound quality of the in-ear wearable device.

[0057] Optionally, the first mounting portion 13 is a curved surface. Of course, in other embodiments, the first mounting portion 13 may also be a plane, etc., and is not limited thereto.

[0058] However, when a user uses an in-ear wearable device, the user's external auditory canal opening 91 is partially or completely blocked. The user's voice can travel through the skull to the external auditory canal. Due to the small volume of the external auditory canal, low-frequency sound reflection is enhanced, resulting in an "echo" or "hole" sensation. Thus, after prolonged use of the in-ear wearable device, the user will experience discomfort, affecting the user experience. Therefore, in this embodiment, the in-ear wearable device also includes a ventilation valve 30. The ventilation valve 30 is located within the receiving cavity 11 and is used to allow or restrict communication between the external auditory canal and the external environment.

[0059] When the ventilation valve 30 is opened, the external auditory canal is connected to the external environment. This allows for dynamic control of the air pressure balance between the ear canal and the external environment, reducing discomfort caused by the blockage of the external auditory canal and thus improving the user's comfort when wearing in-ear wearable devices.

[0060] Optionally, the vent valve 30 is an electronic vent valve. Of course, in other embodiments, the vent valve 30 may be of other types, and is not limited thereto.

[0061] In one embodiment, the housing 10 is provided with a touch portion. In use, the user touches the touch portion to control the opening or closing of the ventilation valve 30, thereby allowing or restricting communication between the external auditory canal and the external environment.

[0062] Of course, in other embodiments, the ventilation valve 30 can also be controlled to open or close via an app. Alternatively, the user can control the ventilation valve 30 to open or close through body movements, such as nodding.

[0063] In one embodiment, see Figure 1 , Figure 5 and Figure 12 The outer shell 10 includes a second mounting portion 14, a third mounting portion 15, and a fourth mounting portion 16. When a user wears an in-ear wearable device, the second mounting portion 14 is positioned to correspond to the user's tragus notch 92, the third mounting portion 15 is positioned to correspond to the user's concha 93, and the fourth mounting portion 16 is positioned to correspond to the user's concha 94.

[0064] It should be noted that the setting of the second mounting part 14 corresponding to the user's tragus notch 92 means that at least a part of the second mounting part 14 is in contact with the user's tragus notch 92, or that at least a part of the projection of the second mounting part 14 on the user's ear is located within the tragus notch 92.

[0065] It should be noted that the setting of the third mounting part 15 corresponding to the user's ear concha 93 means that at least a part of the third mounting part 15 is in contact with the user's ear concha 93, or that at least a part of the projection of the third mounting part 15 on the user's ear is located inside the ear concha 93.

[0066] It should be noted that the fourth mounting part 16 being configured to correspond to the user's concha 94 means that at least a portion of the fourth mounting part 16 is in contact with the user's concha 94, or that at least a portion of the projection of the fourth mounting part 16 onto the user's ear is located within the concha 94.

[0067] Optionally, the second mounting portion 14, the third mounting portion 15, and the fourth mounting portion 16 are curved surfaces. Of course, in other embodiments, the second mounting portion 14, the third mounting portion 15, and the fourth mounting portion 16 may also be flat surfaces, etc., and are not limited thereto.

[0068] Further, see Figure 1 and Figure 21 The ventilation valve 30 is located in one of the second mounting part 14, the third mounting part 15, and the fourth mounting part 16. When the user uses the in-ear wearable device, the first speaker 20 is located at or near the user's external auditory canal opening 91, and the ventilation valve 30 is located in one of the user's tragus notch 92, cymba conchae 93, and conchae cavity 94. In this way, through the reasonable arrangement of the first speaker 20 and the ventilation valve 30, the limited receiving cavity 11 can simultaneously accommodate the first speaker 20 and the ventilation valve 30, solving the problem of ear occlusion, improving the user's comfort when wearing the in-ear wearable device, and also improving the sound quality.

[0069] In one embodiment, see Figure 7 and Figure 9 One of the second mounting part 14, the third mounting part 15, and the fourth mounting part 16 is provided with a receiving groove 141, and at least a portion of the vent valve 30 is disposed within the receiving groove 141. This arrangement saves space, making the in-ear wearable device more compact and facilitating its miniaturization. At the same time, the groove wall of the receiving groove 141 provides stable support for the vent valve 30, preventing it from shifting or loosening, and thus improving the reliability of the vent valve 30 installation.

[0070] It should be noted that the shape and size of the receiving groove 141 are adapted to the vent valve 30. Optionally, the vent valve 30 is a square body, and the receiving groove 141 is a square groove.

[0071] In one embodiment, see Figure 3 The first loudspeaker 20 divides the receiving cavity 11 into a front cavity 111 and a rear cavity 112, and the sound outlet 12 communicates with the front cavity 111. Specifically, the sound outlet 12 is located on the cavity wall of the front cavity 111.

[0072] Further, see Figure 3 and Figure 7The outer shell 10 is provided with a vent 19, which communicates with the rear cavity 112 and the external environment. Specifically, the vent 19 is located on the cavity wall of the rear cavity 112. The vent valve 30 is used to allow or restrict the communication between the front cavity 111 and the rear cavity 112. When the vent valve 30 is closed, the front cavity 111 and the rear cavity 112 are not connected. The external auditory canal is connected to the front cavity 111 through the sound outlet 12, and the rear cavity 112 is connected to the external environment through the vent 19. When the vent valve 30 is open, the external auditory canal is connected to the external environment through the front cavity 111, the vent valve 30, the rear cavity 112, and the vent 19. This allows for dynamic control of the air pressure balance inside and outside the ear canal, thereby reducing discomfort caused by ear canal closure.

[0073] In one embodiment, see Figure 3 and Figure 5 The in-ear wearable device also includes a ventilation channel 18, and a ventilation valve 30 for allowing or restricting the communication between the anterior cavity 111 and the posterior cavity 112 through the ventilation channel 18. By providing the ventilation channel 18, which connects the anterior cavity 111 and the posterior cavity 112, it is easier to dynamically control the air pressure balance inside and outside the ear canal, thereby reducing discomfort caused by ear canal blockage.

[0074] Optionally, see Figure 14 The ventilation channel 18 is formed within the side wall of the outer shell 10. This conceals the ventilation channel 18 within the side wall of the outer shell 10, eliminating the need for additional space in the receiving cavity 11. This provides ample space for other components within the receiving cavity 11 and protects the ventilation channel 18 from impacts and pressure from these components, reducing the risk of ventilation failure due to physical damage during use. Furthermore, the ventilation channel 18 can be formed simultaneously with the outer shell 10, reducing processing steps.

[0075] Optionally, see Figure 5 and Figure 9 The ventilation channel 18 is independent of the outer casing 10. In this way, the shape, size and position of the ventilation channel 18 can be optimized according to actual needs, without being limited by the shape and structure of the outer casing 10.

[0076] In one embodiment, see Figure 9 The receiving grooves 141 are all provided on the cavity wall of the rear cavity 112, and the groove wall of the receiving groove 141 is provided with a connecting hole 1411.

[0077] Further, see Figure 14The ventilation channel 18 has a first end and a second end. The first end is located in the anterior cavity 111, and the second end is located in the posterior cavity 112. The first end has a first vent hole 181, which communicates with the anterior cavity 111. The second end has a second vent hole 182, which communicates with the connecting hole 1411. It should be noted that the sidewalls of the ventilation channel 18 are not connected to the anterior cavity 111 or the posterior cavity 112; that is, the sidewalls of the ventilation channel 18 are isolated from both the anterior cavity 111 and the posterior cavity 112. When the ventilation valve 30 is opened, the first vent hole 181 guides the airflow in the anterior cavity 111 into the ventilation channel 18, and the second vent hole 182 guides the airflow in the ventilation channel 18 into the posterior cavity 112, thereby connecting the external auditory canal with the external environment, reducing the ear blockage effect, and improving wearing comfort.

[0078] In one embodiment, see Figure 9 , Figure 10 and Figure 14 The vent valve 30 is provided with an outlet 34, which is connected to the second vent 182 through a connecting hole 1411. This arrangement facilitates the entry of gas in the venting channel 18 into the vent valve 30 through the second vent 182 and the connecting hole 1411.

[0079] In one embodiment, see Figure 9 , Figure 10 and Figure 18 The vent valve 30 is equipped with a valve 33 and a vent 34. The vent 34 is connected to the front chamber 111 through the venting channel 18. The valve 33 can be opened to allow the vent 34 to communicate with the external environment through the vent hole 19. It should be noted that... (See also...) Figure 18 , Figure 19 and Figure 20 Valve 33 can be fully open, fully closed, or partially open. Valve 33 is also infinitely adjustable, meaning the degree of opening can be adjusted as needed. The external auditory canal is connected to the anterior cavity 111, which is connected to the vent 34 of the vent valve 30 via the venting channel 18, thus connecting the external auditory canal to the vent valve 30. When valve 33 is open, airflow passes through the external auditory canal, venting channel 18, vent 34, valve 33, and vent 19, connecting with the external environment. When valve 33 is closed, the vent valve 30 restricts the connection between the anterior cavity 111 and the posterior cavity 112, thereby restricting the user's external auditory canal from connecting with the external environment.

[0080] In one embodiment, see Figure 3 and Figure 4The in-ear wearable device also includes a mainboard 60 and a flexible circuit board 80, both of which are located within the receiving cavity 11. Optionally, both the mainboard 60 and the flexible circuit board 80 are located within the rear cavity 112. The ventilation valve 30 is electrically connected to the mainboard 60 via the flexible circuit board 80. Thus, the mainboard 60 can control the opening and closing state of the ventilation valve 30 via circuit signals, thereby precisely controlling the air pressure balance inside and outside the external auditory canal, thus reducing discomfort caused by the closure of the external auditory canal. Furthermore, the flexible circuit board 80 can be flexibly arranged within the receiving cavity 11 by bending or folding, enabling the connection of various components within the receiving cavity 11, and also facilitating the miniaturization of the in-ear wearable device.

[0081] Further, see Figure 9 and Figure 10 The flexible circuit board 80 is provided with a through hole 86, which is connected to the vent hole 34 and the ventilation channel 18. This arrangement can prevent the flexible circuit board 80 from blocking the vent hole 34 of the ventilation valve 30, and ensure that the front cavity 111 can be connected to the ventilation valve 30 through the ventilation channel 18.

[0082] Specifically, at least a portion of the flexible circuit board 80 is disposed between the wall of the receiving groove 141 and the vent valve 30, and the vent 34 is connected to the venting channel 18 through the through hole 86 and the connecting hole 1411. This arrangement relatively fixes the flexible circuit board 80 between the wall of the receiving groove 141 and the vent valve 30, reducing the shaking and displacement of the flexible circuit board 80, enhancing the stability of the circuit connection, and reducing the risk of the in-ear wearable device malfunctioning due to circuit failure.

[0083] It should be noted that the vent 34 is connected to the first vent 181 and the second vent 182 of the ventilation channel 18 via the through hole 86 and the connecting hole 1411. When the valve 33 is opened, airflow passes through the external auditory canal, the first vent 181 and the second vent 182 of the ventilation channel 18, the connecting hole 1411, the through hole 86, the vent 34, the valve 33, and the vent 19, connecting to the external environment. This dynamically controls the air pressure balance between the ear canal and the external environment, reducing discomfort caused by the closure of the external auditory canal and thus improving the user's comfort when wearing in-ear wearable devices. The through hole 86 and the connecting hole 1411 ensure the connection between the ventilation valve 30 and the ventilation channel 18.

[0084] In one embodiment, see Figure 3 and Figure 4 The extension direction of the vent valve 30 intersects with the extension direction of the main board 60. Figure 3 and Figure 4For example, the mainboard 60 extends horizontally, and the vent valve 30 extends in a direction intersecting the horizontal direction. With this configuration, the vent valve 30 is located only adjacent to the inner wall of the outer shell 10, and its extension direction is roughly perpendicular to the mainboard 60, so that the vent valve 30 can be compactly arranged in the receiving cavity 11, which is beneficial for the miniaturization of in-ear wearable devices.

[0085] In one embodiment, the in-ear wearable device further includes a protective component disposed on the ventilation valve 30. By providing the protective component, the protective component can effectively prevent moisture, dust, and other impurities from entering the ventilation valve 30 through the rear cavity 112, thereby protecting the ventilation valve 30 and extending its service life.

[0086] Optionally, the protective element is a waterproof mesh fabric, which is disposed within the receiving groove 141 and covers the communicating hole 1411. In one embodiment, see [reference needed]. Figure 3 and Figure 10 The in-ear wearable device also includes a second speaker 21, which is disposed within the receiving cavity 11. Specifically, the second speaker 21 is disposed within the front cavity 111.

[0087] Specifically, the second speaker 21 is a balanced armature unit. A balanced armature unit includes a diaphragm, armature, coil, magnet, etc. When an audio signal passes through the coil, the armature vibrates in the magnetic field, which in turn drives the diaphragm to vibrate, thereby producing sound. In this way, a more balanced sound quality can be achieved through the cooperation of the dynamic coil unit and the balanced armature unit.

[0088] In one embodiment, see Figure 10 and Figure 14 A reinforcing plate 31 is provided on one side of the vent valve 30, and the reinforcing plate 31 is connected to the groove wall of the receiving groove 141. In this way, the structural strength of the vent valve 30 can be improved by the action of the reinforcing plate 31, and the installation firmness of the vent valve 30 can also be improved.

[0089] Optionally, one side of the reinforcing plate 31 is bonded to the vent valve 30 by adhesive 32, and the other side of the reinforcing plate 31 is bonded to the wall of the receiving groove 141 by adhesive 32.

[0090] In one embodiment, see Figure 1 , Figure 4 and Figure 11 The in-ear wearable device also includes an in-ear detector 40. The in-ear detector 40 is disposed within the receiving cavity 11. Specifically, the in-ear detector 40 is disposed within the rear cavity 112. The in-ear detector 40 is electrically connected to the main board 60 via a flexible circuit board 80, and is used to detect whether the in-ear wearable device is worn on the user's ear.

[0091] Optionally, the in-ear detector 40 may be an optical sensor, a skin detection sensor, a barometric pressure sensor, or a photoelectric sensor.

[0092] The in-ear detector 40 is an important sensor whose main function is to detect whether the user is wearing an in-ear wearable device. When the user puts the in-ear wearable device into their ear, the device automatically plays music; when the user removes the device, the music automatically pauses. This not only improves the user experience but also avoids wasting power when the device is not being worn. If the user removes the device and does not return it to the charging case for an extended period, the in-ear detector 40 can trigger the device to enter sleep or power-off mode, thereby saving power.

[0093] In one embodiment, see Figure 1 and Figure 21 The outer casing 10 also includes a fifth mounting portion 17. When a user wears an in-ear wearable device, the fifth mounting portion 17 is positioned to correspond to the user's ear helix foot 95.

[0094] Optionally, the fifth mounting portion 17 is a curved surface. Of course, in other embodiments, the fifth mounting portion 17 may also be a plane, and is not limited thereto.

[0095] Optionally, see Figure 11 and Figure 21 The ventilation valve 30 is located in the second mounting part 14, and the in-ear detector 40 is located in one of the third mounting part 15, the fourth mounting part 16, and the fifth mounting part 17. When the user uses the in-ear wearable device, the ventilation valve 30 is positioned to correspond to the user's tragus notch 92. Since the tragus notch 92 is very close to the ear canal, the posterior cavity 112 can be connected to the anterior cavity 111 through a shorter ventilation channel 18, reducing ventilation resistance. At the same time, the in-ear detector 40 is positioned to correspond to the user's helix foot 95, concha 94, or cymba concha 93, thus avoiding interference between the ventilation valve 30 and the in-ear detector 40 during installation.

[0096] Optionally, see Figure 1 , Figure 5 and Figure 21 The ventilation valve 30 is located in the third mounting part 15, and the in-ear detector 40 is located in one of the second mounting part 14, the fourth mounting part 16, and the fifth mounting part 17. When the user uses the in-ear wearable device, the ventilation valve 30 is positioned to correspond to the user's concha 93. Since the concha 93 is spacious, it is easy to assemble and seal the ventilation valve 30. At the same time, the in-ear detector 40 is positioned to correspond to the user's tragus notch 92, concha 94, or helix 95, thus avoiding interference between the ventilation valve 30 and the in-ear detector 40 during installation.

[0097] Optionally, the ventilation valve 30 is located in the fourth mounting part 16, and the in-ear detector 40 is located in one of the second mounting part 14, the third mounting part 15, and the fifth mounting part 17. When the user uses the in-ear wearable device, the ventilation valve 30 is positioned to correspond to the user's concha 94, and the in-ear detector 40 is positioned to correspond to the user's tragus notch 92, cymba concha 93, or helix crus 95. This avoids interference between the ventilation valve 30 and the in-ear detector 40 during installation.

[0098] In one embodiment, see Figure 7 and Figure 9 One of the second mounting part 14, the third mounting part 15, the fourth mounting part 16, and the fifth mounting part 17 is provided with a detection hole 171, and a portion of the in-ear detector 40 is disposed within the detection hole 171. Optionally, the in-ear detector 40 is an optical detector. During detection, the in-ear detector 40 is in contact with the user's skin, and the in-ear detector 40 must be protected from light.

[0099] In one embodiment, see Figure 2 and Figure 3 The in-ear wearable device also includes a motherboard 60 and a battery 70, both of which are housed within a receiving cavity 11. Specifically, both the motherboard 60 and the battery 70 are located within a rear cavity 112. The battery 70 is electrically connected to the motherboard 60 via a terminal block. Thus, the battery 70 can provide power to the various functional components within the in-ear wearable device, ensuring their reliable operation.

[0100] Further, see Figure 3 The battery 70 is located between the motherboard 60 and the first speaker 20. In this way, the space of the rear cavity 112 can be fully utilized, which is conducive to improving space utilization.

[0101] In one embodiment, see Figure 3 and Figure 5 The in-ear wearable device also includes a charging component 50, which is disposed within the receiving cavity 11 and electrically connected to the main board 60 via a flexible circuit board 80. Specifically, the charging component 50 is disposed within the rear cavity 112 and electrically connected to the main board 60. By providing the charging component 50, the charging component 50 can convert electrical energy from an external power source into electrical energy required by the battery 70 and store it in the battery 70, thereby replenishing the energy consumed by the battery 70 during use.

[0102] In one embodiment, see Figure 5 , Figure 12 , Figure 13 and Figure 21The ventilation valve 30 is located in one of the second mounting portion 14 and the third mounting portion 15, and the charging component 50 is located in the fourth mounting portion 16. When the user uses the in-ear wearable device, the ventilation valve 30 is positioned to correspond to the user's cymba conchae 93 or tragus notch 92, and the charging component 50 is positioned to correspond to the user's canthus conchae 94. In this way, interference between the ventilation valve 30 and the charging component 50 during installation can be avoided.

[0103] It should be noted that if the ventilation valve 30 is located in the fourth mounting part 16, the charging component 50 may be located in another position on the housing, or the in-ear wearable device may not include the charging component 50.

[0104] Optionally, the ventilation valve 30 is located in the third mounting part 15, the charging component 50 is located in the fourth mounting part 16, and the in-ear detector 40 is located in the fifth mounting part 17. When the user uses the in-ear wearable device, the ventilation valve 30 is positioned corresponding to the user's concha 93. Due to the open position of the concha 93, it is easy to assemble and seal the ventilation valve 30. Since the surface of the concha 94 is larger and flatter and more regular than other parts of the human ear, the installation between the charging component 50 and the outer shell 10 is less affected by the outer shell 10, which helps to ensure the convenience and reliability of the installation between the outer shell 10 and the charging component 50, and also effectively ensures the comfort of wearing the in-ear wearable device. The in-ear detector 40 is located at the helix foot 95, which avoids interference between the in-ear detector 40, the ventilation valve 30 and the charging component 50, and also avoids the in-ear detector 40 being affected by light, thus affecting the detection results.

[0105] Further, see Figure 5 , Figure 8 and Figure 15 The fourth mounting part 16 is provided with a charging hole 161, and at least a portion of the charging component 50 is disposed within the charging hole 161. By providing the charging hole 161, the charging component 50 can be electrically connected to a power supply device outside the in-ear wearable device.

[0106] In one embodiment, see Figure 10 and Figure 17 The ventilation valve 30, in-ear detector 40, and charging component 50 are all electrically connected to the mainboard 60 via the flexible circuit board 80. It is understood that the ventilation valve 30, in-ear detector 40, and charging component 50 form a combined hardware unit via the flexible circuit board 80. This reduces the number of connectors on the mainboard 60, thereby reducing the space required for the mainboard 60 to connect to the three devices, allowing the structure to be better integrated with smaller in-ear wearable devices.

[0107] In one embodiment, see Figure 10 and Figure 17The flexible circuit board 80 includes a main body segment 81, a first branch segment 82, a second branch segment 83, and a third branch segment 84. The main body segment 81 is electrically connected to the main board 60, and the first branch segment 82, the second branch segment 83, and the third branch segment 84 are all electrically connected to the main body segment 81. The ventilation valve 30 is electrically connected to the first branch segment 82, the in-ear detector 40 is electrically connected to the second branch segment 83, and the charging component 50 is electrically connected to the third branch segment 84. This arrangement allows the ventilation valve 30, the in-ear detector 40, and the charging component 50 to be reliably connected to the main board 60 via the flexible circuit board 80.

[0108] Further, see Figure 10 and Figure 17 At least one of the main body segment 81, the first branch segment 82, the second branch segment 83, and the third branch segment 84 is provided with a bending portion 85. With this configuration, during the assembly of the in-ear wearable device, the positions of the ventilation valve 30, the in-ear detector 40, and the charging component 50 can be adjusted by bending or stretching the bending portion 85, so that the ventilation valve 30, the in-ear detector 40, and the charging component 50 can be reliably installed in specific positions within the receiving cavity 11, thereby ensuring that the ventilation valve 30, the in-ear detector 40, and the charging component 50 can be quickly installed on in-ear wearable devices of different sizes.

[0109] In one embodiment, when the flexible circuit board 80 is unfolded, the ventilation valve 30, the in-ear detector 40, and the charging component 50 are located on the same side of the flexible circuit board 80. Because the flexible circuit board 80 is thin, light, and flexible, placing the ventilation valve 30, the in-ear detector 40, and the charging component 50 on the same side of the flexible circuit board 80 makes better use of limited space, resulting in a more compact in-ear wearable device. Furthermore, it reduces assembly time and improves assembly efficiency.
