Description

Technical Field

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

[0002] With the increasing application of mobile devices such as smartphones, and the increasing use of audio and video services, wireless headphones have rapidly 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 for a long time, thus limiting the wearing time and application scenarios. In addition, if in-ear wireless headphones are 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. Moisture infection may also occur due to the lack of ventilation in the ear canal.

[0003] To this end, there is a need for an in-ear wearable device and an in-ear wireless headset with improved wearing comfort. Summary of the Invention

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] According to certain embodiments of the present invention, the customized housing 100 includes a first portion for insertion into a user's ear canal and conforming 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. This "customization" allows the customized housing 100 to at least partially conform to the user's ear canal when the user wears the in-ear wireless earphones 10. Thus, the first portion of the customized housing 100 serves as the portion that conforms to the user's ear canal, i.e., the portion that is isolated from the external environment, thereby providing a sealed listening environment within the ear canal when the user wears the in-ear wireless earphones 10. Furthermore, the second portion of the customized housing 100 serves as the portion that is exposed to the external environment when the user wears the in-ear wireless earphones 10. In some embodiments, the second portion of the customized housing 100 includes an open end. The open end is located on a side of the second portion away from the first portion. In some embodiments, the faceplate 200 is attached 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 earphones 10 can be arranged within the customized housing 100 through the open end, and then the faceplate 200 is attached to the open end.

[0108] 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.

[0109] 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.

[0110] 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 flow 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 can be formed together when the customized shell 100 is manufactured, or can be additionally formed in the shell wall 110 after the customized shell 100 is manufactured. According to some embodiments of the present invention, 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 is configured to be electrically operated to adjust the ventilation volume of the ventilation channel. Specifically, the ventilation volume adjustment device 400 can be electrically operated to open and close the vent hole 300, thereby opening and closing the ventilation channel. Thus, the ventilation channel can be ventilated when the ventilation volume adjustment device 400 is open, and can provide a better listening experience when the ventilation volume adjustment device 400 is closed.

[0115] 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.

[0116] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 can be electrically operated to switch 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 volume. In the fully closed state, the ventilation channel is in a completely closed state, thereby preventing ventilation.

[0117] In some embodiments, in addition to the fully open and fully closed states described above, the ventilation volume adjustment device 400 can also be electrically 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 electrically operated to be in a 25% open state, a 50% open state, a 75% open state, and so on.

[0118] In some embodiments, the ventilation volume adjustment device 400 can also be electrically operated to continuously adjust the ventilation volume of the ventilation channel. Thus, the ventilation volume adjustment device 400 can be infinitely adjusted.

[0119] 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 ventilation volume adjustment device 400 is electrically operated 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 ventilation volume adjustment device 400 is electrically operated 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 conveniently adjust his or her listening experience to meet different needs.

[0120] According to certain embodiments of the present invention, the ventilation volume regulating device 400 can be controlled by wire or wirelessly to electrically adjust the ventilation volume of the ventilation channel. In some embodiments, the ventilation volume regulating device 400 can be connected to a wired or wireless terminal device for communication, such as a computer, a mobile phone, a tablet computer, an audio reproduction device, a video processing device, a game console, a navigation device, etc., and receive a control signal from the wired or wireless terminal device. According to the corresponding control signal, the ventilation volume regulating device 400 can electrically adjust the ventilation volume of the ventilation channel. For example, a user can send an instruction to adjust the ventilation volume of the ventilation channel through an application software (APP) on a mobile phone, so that the ventilation volume regulating device 400 can adjust the ventilation volume of the ventilation channel through electric operation according to the instruction.

[0121] 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.

[0122] According to certain embodiments of the present invention, the ventilation volume regulating device 400 is configured not to be exposed from the outer surface of the customized shell 100. Thus, except for the first orifice 300A and the second orifice 300B of the vent 300, the ventilation volume regulating device 400 is wrapped by the customized shell 100 and cannot be observed or touched from the outside. By preventing the ventilation volume regulating device 400 from being exposed from the outer surface of the customized shell 100, the ventilation volume regulating device 400 will not have its components contact the user's ears when electrically adjusted, thereby improving the user experience and improving the accuracy of ventilation volume regulation. In addition, the ventilation volume regulating device 400 being wrapped by the customized shell 100 can avoid or reduce the entry of external foreign matter or contaminants into the ventilation volume regulating device 400, thereby improving the stability of the ventilation volume regulating device 400 and the in-ear wireless headset 10.

[0123] According to certain embodiments of the present invention, a ventilation volume regulating device 400 includes a movable portion, a fixed portion, and an electric actuator. The electric actuator can drive the movable portion to move relative to the fixed portion to adjust the ventilation volume of the ventilation channel. The ventilation volume regulating device according to certain embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0124] Solenoid valve structure

[0125] According to some embodiments of the present invention, the ventilation volume regulating device may adopt a solenoid valve structure. Figure 4A is a perspective view of an in-ear wireless headset according to some embodiments of the present invention. Figure 4B is a schematic cross-sectional view of an in-ear wireless headset according to some embodiments of the present invention. Figure 4C 2 is a schematic diagram of a ventilation volume adjustment device for an in-ear wireless headset according to some embodiments of the present invention. Figure 4D is a schematic cross-sectional view of a ventilation volume regulating device in an open state according to certain embodiments of the present invention. Figure 4E is a schematic cross-sectional view of a ventilation volume regulating device in a closed state according to certain embodiments of the present invention.

[0126] like Figure 4AAs shown, the in-ear wireless headset 10 includes a customized housing 100, a panel 200 and a vent 300. Figure 4B As shown, the vent 300 of the in-ear wireless headset 10 is provided in the custom housing 100 and includes a mounting position 300C for mounting the ventilation volume adjustment device 400. In an exemplary embodiment, as shown in FIG. Figure 4B As shown, the mounting position 300C is located in the vent 300 at a position spaced apart from both the first opening 300A and the second opening 300B, i.e., in the middle of the vent 300. In some embodiments, the mounting position 300C can be located at the first opening 300A or the second opening 300B of the vent 300. The other components and structures of the in-ear wireless headset 10 are described above and will not be repeated here.

[0127] In some embodiments, the extension direction of the vent hole 300 at the installation position 300C is substantially straight. For example, the vent hole 300 is a straight vent hole, or the vent hole 300 is a bent vent hole as a whole but has a straight section at the installation position 300C.

[0128] According to some embodiments of the present invention, Figures 4C to 4E As shown, the ventilation volume regulating device 400 includes a piston 410 ( Figure 4C ), a housing 420 as a fixed portion and an electromagnetic unit 430 as an electric actuator. The housing 420 includes an opening 421 communicating with the vent 300. The piston 410 is disposed inside the valve body 420. The piston 410 can move relative to the housing 420 under the action of the electromagnetic unit 430. In some embodiments, as Figure 4D and Figure 4E As shown, the housing 420 includes an internal chamber 422 in which the piston 410 can move. In the exemplary embodiment, the movement direction of the piston 410 is substantially parallel to the extension direction of the vent hole 300 at the air volume adjustment device 400. Herein, "the extension direction of the vent hole 300 at the air volume adjustment device 400" refers to the extension direction of the vent hole 300 at the installation location 300C, that is, the centerline of the vent hole 300 at the installation location 300C.

[0129] In some embodiments, as Figure 4D and Figure 4E As shown, electromagnetic unit 430 includes an electromagnetic coil 431, and piston 410 includes a magnet. Electromagnetic coil 431 generates an electromagnetic field when energized. In some embodiments, electromagnetic coil 431 is disposed radially around piston 410 as viewed in the direction of movement of piston 410. Electromagnetic coil 431 may be fixed to or within housing 420.

[0130] In some embodiments, the electromagnetic unit 430 may further include a power cord 432 for providing a driving current to the coil 431. In some embodiments, the power cord 432 is electrically connected to a battery (not shown) of the in-ear wireless headset 10. Figure 4B As shown, the customized housing 110 includes a window 150 facing the inner cavity 120 , whereby the power line 432 of the electromagnetic unit 430 can pass through the window 150 to be electrically connected to the battery of the in-ear wireless headset 10 .

[0131] According to certain embodiments of the present invention, the ventilation volume regulating device 400 can adjust the ventilation volume of the ventilation channel by driving the piston 410 to move relative to the housing 420 by the electromagnetic unit 430. Specifically, when the electromagnetic coil 431 is energized, an electromagnetic field is generated inside the electromagnetic coil 431, causing the piston 410 to open or close the opening 421 of the housing 420 under the action of the magnetic field, thereby opening or closing the ventilation channel or adjusting the degree of opening of the ventilation channel. When the electromagnetic coil 431 is de-energized, the electromagnetic coil 431 will no longer generate an electromagnetic field, causing the piston 410 to return to a position that closes or opens the opening 421 of the housing 420, thereby closing or opening the ventilation channel. In an exemplary embodiment, the piston 410 of the ventilation volume regulating device 400 is in a state of closing the opening 421 of the housing 420 when the electromagnetic coil 431 is not energized.

[0132] According to some embodiments of the present invention, the housing 420 includes two openings 421 communicating with the vent hole 300, one on each side of the piston 410. Figure 4D and Figure 4E As shown, the electromagnetic unit 430 further includes a stopper 433. When the piston 410 moves relative to the housing 420 under the action of the electromagnetic coil 431 to open one opening 421 of the housing 420, the stopper 433 can limit the movement range of the piston 410 to prevent the piston 410 from moving to a position closing the other opening 421 of the housing 420.

[0133] In some embodiments, the ventilation volume adjustment device 400 further includes a connecting tube 440. The connecting tube 440 is in fluid communication with the opening 421 of the housing 420. The ventilation volume adjustment device 400 is connected to the vent 300 of the in-ear wireless headset 10 via the connecting tube 440. The connecting tube 440 connects the housing 420 of the ventilation volume adjustment device 400 to the vent 300. In some embodiments, the connecting tube 440 is a flexible connecting tube. The ventilation volume adjustment device 400 can more advantageously isolate the ventilation channel of the in-ear wireless headset 10 from the inner cavity 120 through the connecting tube 440. However, the method for isolating the ventilation channel from the inner cavity of the present invention is not limited thereto.

[0134] In some embodiments, the housing 420 is a separate housing from the customized housing 100. However, the present invention is not limited thereto. In some embodiments, the housing 420 may be formed by the customized housing 100, that is, the housing 420 may be integrally formed with the customized housing 100.

[0135] Referenced above Figures 4A to 4E The ventilation volume regulating device 400 having a solenoid valve structure is described. However, the present invention is not limited thereto. Other ventilation volume regulating devices 400 having a solenoid valve structure will be described below with reference to the accompanying drawings.

Figure 5B 2 is a schematic exploded view of a ventilation volume regulating device for an in-ear wireless headset according to some embodiments of the present invention. Figure 5C is a schematic cross-sectional view of a ventilation volume regulating device in an open state according to certain embodiments of the present invention. Figure 5D is a schematic cross-sectional view of a ventilation volume regulating device in a closed state according to certain embodiments of the present invention.

[0137] like Figure 5A As shown, the in-ear wireless earphone 10 includes a custom housing 100, a panel 200, and a vent 300. The vent 300 of the in-ear wireless earphone 10 is provided in the custom housing 100 and includes a mounting position 300C for mounting the ventilation volume adjustment device 400. In an exemplary embodiment, as shown in FIG. Figure 5A As shown, the mounting position 300C is located in the vent 300 at a position spaced apart from both the first opening 300A and the second opening 300B, i.e., in the middle of the vent 300. In some embodiments, the mounting position 300C can be located at the first opening 300A or the second opening 300B of the vent 300. The other components and structures of the in-ear wireless headset 10 are described above and will not be repeated here.

[0138] According to some embodiments of the present invention, Figures 5B to 5D As shown, the ventilation volume regulating device 400 includes a piston 410 as a movable part, a housing 420 as a fixed part, and an electromagnetic unit 430 as an electric actuator. The housing 420 includes an opening 421 connected to the vent hole 300. The piston 410 is disposed inside the valve body 420. The piston 410 can move relative to the housing 420 under the action of the electromagnetic unit 430. In some embodiments, as Figure 5C and Figure 5DAs shown, the housing 420 includes an internal chamber 422 in which the piston 410 can move. In an exemplary embodiment, the movement direction of the piston 410 intersects with the extension direction of the vent hole 300 at the air volume adjustment device 400, for example, is substantially perpendicular.

[0139] In some embodiments, electromagnetic unit 430 includes an electromagnet 434, and piston 410 includes a magnet. Electromagnet 434 exhibits magnetism when energized. In some embodiments, electromagnet 434 is positioned so as to at least partially overlap piston 410 when viewed along the direction of movement of piston 410. Electromagnet 434 may be fixed to or within housing 420.

[0140] In some embodiments, the electromagnetic unit 430 may further include a power cord 432 for providing a driving current to the electromagnet 434. In some embodiments, the power cord 432 is electrically connected to a battery (not shown) of the in-ear wireless headset 10. Figure 5A As shown, the customized housing 110 includes a window 150 facing the inner cavity 120 , whereby the power line 432 of the electromagnetic unit 430 can pass through the window 150 to be electrically connected to the battery of the in-ear wireless headset 10 .

[0141] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 can adjust the ventilation volume of the ventilation channel by driving the piston 410 relative to the housing 420 by the electromagnet 434. Specifically, when the electromagnet 434 is energized, the electromagnet 434 generates magnetism to attract or repel the piston 410, thereby opening or closing the opening 421 of the housing 420, thereby opening or closing the ventilation channel or adjusting the degree of opening of the ventilation channel. When the electromagnet 434 is de-energized, the magnetism of the electromagnet 434 disappears, causing the piston 410 to return to a position that closes or opens the opening 421 of the housing 420, thereby closing or opening the ventilation channel. In an exemplary embodiment, the piston 410 of the ventilation volume adjustment device 400 is in a state of closing the opening 421 of the housing 420 when the electromagnet 434 is not energized.

[0142] In some embodiments, as Figure 5C and Figure 5D As shown, electromagnetic unit 430 further includes a magnetic restriction 435. Magnetic restriction 435 may be a magnet or an electromagnet. For example, when electromagnet 434 is de-energized, piston 410 may be attracted or repelled by magnetic restriction 435 to return to a position closing or opening opening 421 of housing 420. In some embodiments, magnetic restriction 435 may also limit the range of movement of piston 410, as described above with reference to stop 433.

Figure 6D is a schematic cross-sectional view of a ventilation volume regulating device in a closed state according to certain embodiments of the present invention.

[0146] like Figure 6A As shown, the in-ear wireless headset 10 includes a custom housing 100, a panel 200 and a vent 300. The vent 300 of the in-ear wireless headset 10 is provided in the custom housing 100 and includes a mounting means for mounting a ventilation volume adjustment device 400 ( Figure 6A In an exemplary embodiment, as shown in FIG. Figure 6A As shown, the mounting position 300C is set at a position in the vent hole 300 that is spaced apart from the first orifice 300A and the second orifice 300B, that is, at the middle position of the vent hole 300. In some embodiments, the mounting position 300C can be set at the second orifice 300B of the vent hole 300. 6A to 6D In the illustrated embodiment, other components and structures of the in-ear wireless headset 10 are as described above and will not be described in detail here.

[0149] According to certain embodiments of the present invention, the ventilation volume regulating device 400 further includes a first engaging portion 551 for anti-twistably connecting to the valve plate 510 and a second engaging portion 552 for anti-twistably connecting to the output shaft 531 of the motor 530. The first engaging portion 551 and the second engaging portion 552 are drivingly engaged with each other. In an exemplary embodiment, as Figures 6B to 6D As shown, the first engaging portion 551 and the second engaging portion 552 are respectively toothed engaging portions, whereby the first engaging portion 551 and the second engaging portion 552 mesh with each other.

However, the present invention is not limited to this. In other embodiments, the first engaging portion 551 and the second engaging portion 552 can be other types of toothed engaging portions, as long as they can mesh with each other to drive the valve plate 510 to rotate.

[0150] In some embodiments, the first engaging portion 551 is integrally formed with the valve plate 510. However, the present invention is not limited thereto. In some embodiments, the valve plate 510 and the first engaging portion 551 may be formed separately and connected together. For example, the valve plate 510 and the first engaging portion 551 may be connected to each other using an adhesive, threads, or the like.

[0151] In some embodiments, as Figure 6A As shown, the customized housing 110 includes a window 150 facing the inner cavity 120, and a power line (not shown) of the motor 530 can be electrically connected to a battery (not shown) of the in-ear wireless headset 10 through the window 150.

[0152] According to certain embodiments of the present invention, the ventilation volume regulating device 400 can regulate the ventilation volume of the ventilation channel by driving the valve plate 510 to rotate by the motor 530. Specifically, when the motor 530 is energized, the output shaft 531 and the second engaging portion 552 of the motor 530 rotate, thereby driving the first engaging portion 551 and the valve plate 510 to rotate relative to the valve body 520, thereby opening or closing the ventilation channel or regulating the degree of opening of the ventilation channel.

The rotating cover 610 includes an opening 611, and the base 620 includes an opening 621. The rotating cover 610 can rotate relative to the base 620. As the rotating cover 610 rotates relative to the base 620, the opening 611 of the rotating cover 610 and the opening 621 of the base 620 can communicate with each other and with the vent hole 300, thereby achieving ventilation of the ventilation channel.

[0160] In some embodiments, as Figures 7B to 7D As shown, the rotating cover 610 is arranged to at least partially overlap with the base 620 along the rotation axis of the rotating cover 610. In some embodiments, the rotating cover 610 is arranged closer to the second opening 300B of the vent 300 relative to the base 620, that is, when the user wears the in-ear wireless headset 10, the rotating cover 610 is closer to the external environment. However, the present invention is not limited to this. In other embodiments, the rotating cover 610 is arranged farther away from the second opening 300B of the vent 300 relative to the base 620, that is, when the user wears the in-ear wireless headset 10, the rotating cover 610 is closer to the user's ear canal.

[0161] In an exemplary embodiment, the rotation axis of the rotating cover 610 is substantially parallel to the direction in which the vent holes 300 extend at the ventilation volume adjustment device 400.

The opening 611 of the rotating cover 610 is formed by being surrounded by the annular cavity 612 and the connecting portion 613. In addition, the base 620 includes an annular cavity 622 and a connecting portion 623, and the connecting portion 623 is arranged in the annular cavity 622. The opening 621 of the base 620 is formed by being surrounded by the annular cavity 622 and the connecting portion 623. The rotating cover 610 and the base 620 are respectively arranged in the vent 300 through the annular cavities 612 and 622. 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.

[0163] In some embodiments, as Figure 7BAs shown, the ventilation volume regulating device 400 further includes a rotating cover fixing member 640 and a pin 650 disposed at an end of the base 620 away from the rotating cover 610. The base 620 includes a through hole. The pin 650 passes through the base 620 and connects the rotating cover 610 and the rotating cover fixing member 640 to fix and constrain the rotating cover 610. In an exemplary embodiment, the pin 650 is fixedly connected to the rotating cover fixing member 640. In some embodiments, the pin 650 includes an external thread (such as Figure 7B As shown), the rotating cover 610 includes an internal threaded hole (not shown), and the pin 650 passes through the base 620 to be threadedly engaged with the internal threaded hole of the rotating cover 610, thereby connecting the rotating cover 610 and the rotating cover fixing member 640 to each other.

[0164] According to some embodiments of the present invention, the pin 650 and the rotating cover fixing member 640 are connected to each other in a torsionally non-rotatable manner. Figure 7B As shown, the pin 650 is integrally formed with the rotating cover fixing member 640. In some embodiments, the pin 650 and the rotating cover fixing member 640 can be formed separately and connected together. For example, the pin 650 and the rotating cover fixing member 640 can be connected to each other by an adhesive, a thread, etc.

[0165] According to some embodiments of the present invention, the ventilation volume regulating device 400 further includes a first engaging portion 661 for anti-twist connection with the rotating cover 610 and a second engaging portion 662 for anti-twist connection with the output shaft 631 of the motor 630. The first engaging portion 661 and the second engaging portion 662 are drivingly engaged with each other. In an exemplary embodiment, as Figures 7B to 7D As shown, the first engagement portion 661 and the second engagement portion 662 are respectively toothed engagement portions, whereby the first engagement portion 661 and the second engagement portion 662 mesh with each other. In the exemplary embodiment, the first engagement portion 661 is a spur gear, and the second engagement portion 662 is a spur gear. However, the present invention is not limited to this. In other embodiments, the first engagement portion 661 and the second engagement portion 662 can be other types of toothed engagement portions, as long as they can mesh with each other to drive the rotating cover 610 to rotate.

[0166] In some embodiments, the first engaging portion 661 is integrally formed with the rotating cover 610. However, the present invention is not limited thereto. In some embodiments, the rotating cover 610 and the first engaging portion 661 may be formed separately and connected together. For example, the rotating cover 610 and the first engaging portion 661 may be connected to each other by an adhesive, a thread, or the like.

[0167] In some embodiments, as Figure 7AAs shown, the customized housing 110 includes a window 150 facing the inner cavity 120, and a power line (not shown) of the motor 630 can be electrically connected to a battery (not shown) of the in-ear wireless headset 10 through the window 150. In some embodiments, the motor 630 of the ventilation volume adjustment device 400 can be arranged in the inner cavity 120 of the housing wall 110 through the window 150.

[0168] According to certain embodiments of the present invention, the ventilation volume regulating device 400 can regulate the ventilation volume of the ventilation channel by driving the rotating cover 610 to rotate relative to the base 620 via the motor 630. Specifically, when the motor 630 is energized, the output shaft 631 and the second engaging portion 662 of the motor 630 rotate, thereby driving the first engaging portion 661 and the rotating cover 610 to rotate relative to the base 620, thereby opening or closing the ventilation channel or regulating the degree of opening of the ventilation channel.

[0169] Referenced above 7A to 7D A ventilation volume regulating device 400 having an open rotary cover structure according to certain embodiments of the present invention is described. However, those skilled in the art will appreciate that the open rotary cover structure of the present invention is not limited thereto. A ventilation volume regulating device having an open rotary cover structure according to certain embodiments of the present invention will be described below.

[0170] In some embodiments, 7A to 7D Unlike the embodiment shown, the base 620 may not have an annular cavity. Thus, the opening 621 of the base 620 is formed by being surrounded by the adjacent connecting portion 623 and the inner wall of the vent hole 300 . Figure 8 is a perspective view of an in-ear wireless headset according to some embodiments of the present invention. Figure 8 As shown, the vent 300 includes a connection portion 623 ( Figure 8 When the base 620 of the ventilation volume adjustment device 400 is positioned in the vent hole 300, the connection portion 623 of the base 620 is at least partially located in the corresponding slot. This allows the base 620 to be more securely positioned in the vent hole 300, preventing rotation of the base 620 and facilitating the electrically operated rotation of the rotating cover 610 relative to the base 620.

[0171] In the above description, the pin 650 is first fixedly connected to the rotating cover fixing member 640 (e.g., formed integrally), and then the pin 650 is connected to the rotating cover 610. However, the present invention is not limited to this. In some embodiments, the pin 650 can be first fixedly connected to the rotating cover 610 (e.g., formed integrally), and then connected to the rotating cover fixing member 640. For example, the pin 650 and the rotating cover 610 can be connected to each other by an adhesive, threads, etc., or formed integrally.

Figure 9B is a schematic cross-sectional view of an in-ear wireless headset according to some embodiments of the present invention. Figure 9C 2 is a schematic exploded view of a ventilation volume regulating device for an in-ear wireless headset according to some embodiments of the present invention. Figure 9D is a schematic diagram of a ventilation volume regulating device according to some embodiments of the present invention. Figure 9E is a partial cross-sectional schematic diagram of a ventilation volume regulating device in an open state according to certain embodiments of the present invention. Figure 9F is a partial cross-sectional schematic diagram of a ventilation volume regulating device in a closed state according to certain embodiments of the present invention.

[0174] like Figure 9A As shown, the in-ear wireless headset 10 includes a customized housing 100, a panel 200 and a vent 300. Figure 9B As shown, the vent 300 of the in-ear wireless headset 10 is provided in the custom housing 100 and includes a device for installing a ventilation volume adjustment device 400 ( Figure 9B In an exemplary embodiment, as shown in FIG. Figure 9B As shown, the mounting position 300C is set at the second orifice 300B of the vent 300. In some embodiments, the mounting position 300C is set at a position in the vent 300 that is spaced apart from the first orifice 300A and the second orifice 300B, that is, at the middle position of the vent 300. 9A to 9F In the illustrated embodiment, other components and structures of the in-ear wireless headset 10 are as described above and will not be described in detail here.

[0175] According to some embodiments of the present invention, Figures 9C to 9F As shown, the ventilation volume regulating device 400 includes a valve core 710 as a movable portion, a valve seat 720 as a fixed portion, and a motor 730 as an electric actuator.

In some embodiments, as Figure 9C and Figure 9D As shown, the first engagement portion 741 and the second engagement portion 742 are each a toothed engagement portion, whereby the first engagement portion 741 and the second engagement portion 742 mesh with each other. In the exemplary embodiment, the first engagement portion 741 is a helical rack, and the second engagement portion 742 is a helical cylindrical tooth. However, the present invention is not limited to this. In other embodiments, the first engagement portion 741 and the second engagement portion 742 can be other types of toothed engagement portions, as long as they can mesh with each other to drive the valve core 710 to move.

[0177] In some embodiments, the first engaging portion 741 and the valve core 710 are independent components. However, the present invention is not limited thereto. In some embodiments, the first engaging portion 741 and the valve core 710 may be fixedly connected to each other. For example, the first engaging portion 741 and the valve core 710 may be connected to each other via an adhesive, threads, etc. In some embodiments, the first engaging portion 741 and the valve core 710 may be integrally formed.

[0178] In some embodiments, as Figure 9C 、 Figure 9E and Figure 9F As shown, the ventilation volume regulating device 400 further includes a spring 750. The spring 750 is configured to apply an elastic force to the valve core 710.

[0185] According to some embodiments of the present invention, FIG. 10B to FIG. 10DAs shown, the ventilation volume adjustment device 400 includes a plurality of blades 810 as a movable portion, a fixed base 820 as a fixed portion, a rotating ring 830, and a motor 840 as an electric actuator. The fixed base 820 includes a fluid channel 821 connected to the vent 300. The rotating ring 830 can rotate relative to the fixed base 820. The motor 840 can drive the rotating ring 830 to rotate, thereby driving the blades 810 to move relative to the fixed base 820. Through the rotation of the rotating ring 830 relative to the fixed base 820, the plurality of blades 810 can be moved together to close the fluid channel 821 of the fixed base 820 or separated from each other to open the fluid channel 821 of the fixed base 820, thereby adjusting the ventilation volume of the ventilation channel.

In some embodiments, the motor 840 of the ventilation volume adjustment device 400 can be arranged in the inner cavity 120 of the housing wall 110 through the window 150.

[0191] According to certain embodiments of the present invention, the ventilation volume adjustment device 400 can adjust the ventilation volume of the ventilation channel by driving the rotation ring 830 to rotate relative to the fixed base 820 via the motor 840, thereby causing the blade 810 to move relative to the fixed base 820. Specifically, when the motor 840 is energized, the output shaft 841 and the second joint 852 of the motor 840 rotate, thereby driving the first joint 851 and the rotation ring 830 to rotate, thereby causing the blade 810 to move relative to the fixed base 820, thereby opening or closing the ventilation channel or adjusting the degree of opening of the ventilation channel.

[0192] Plug-in structure

[0194] like Figure 11AAs shown, the in-ear wireless headset 10 includes a customized housing 100, a panel 200 and a vent 300. Figure 11B As shown, the vent 300 of the in-ear wireless headset 10 is provided in the custom housing 100 and includes a device for installing a ventilation volume adjustment device 400 ( Figure 11B In an exemplary embodiment, as shown in FIG. Figure 11B As shown, the installation position 300C is set at the second orifice 300B of the vent 300. In some embodiments, the ventilation volume adjustment device 400 can be installed in the vent 300 at a position spaced apart from the first orifice 300A and the second orifice 300B, that is, at the middle position of the vent 300. Figures 11A to 11H In the illustrated embodiment, other components and structures of the in-ear wireless headset 10 are as described above and will not be described in detail here.

[0195] According to some embodiments of the present invention, Figures 11C to 11H As shown, the ventilation volume regulating device 400 includes a plug member 910 as a movable part, a plug seat 920 as a fixed part, and a motor 930 as an electric actuator. The plug seat 920 includes a fluid channel 921 for communicating with the vent 300. The plug seat 920 is fixed in the vent 300 of the in-ear wireless headset 10. In an exemplary embodiment, the plug seat 920 is a separate mounting seat, that is, it is formed separately from the custom housing 100. The plug member 910 can be moved relative to the plug seat 920 to close or open the fluid channel 921 of the plug seat 920, thereby opening or closing the ventilation channel or adjusting the ventilation volume of the ventilation channel.

[0196] According to some embodiments of the present invention, the plug 910 can move linearly relative to the plug seat 920. In an exemplary embodiment, the movement direction of the plug 910 is substantially parallel to the extension direction of the vent hole 300 at the ventilation volume regulating device 400. In an exemplary embodiment, as shown in FIG. Figures 11C to 11H As shown, the plug 910 can be inserted into or removed from the plug seat 920.

[0197] In some embodiments, as Figures 11C to 11H As shown, the plug 910 includes a fluid channel 911. The fluid channel 911 of the plug 910 can be used to connect the fluid channel 921 of the plug seat 920 and the external environment. When the plug 910 is inserted into the plug seat 920, the fluid channel 911 of the plug 910 is in fluid communication with the fluid channel 921 of the plug seat 920.

[0198] According to certain embodiments of the present invention, the ventilation volume regulating device 400 further includes a first engaging portion 941 for engaging with the plug 910 and a second engaging portion 942 for torsionally connecting to the output shaft 931 of the motor 930. The first engaging portion 941 and the second engaging portion 942 are drivingly engaged with each other. In an exemplary embodiment, as shown in FIG. Figure 11C As shown, the first engaging portion 941 includes an internal thread, and the second engaging portion 942 includes an external thread, and the first engaging portion 941 and the second engaging portion 942 are threadedly engaged with each other. However, the present invention is not limited to this. In other embodiments, the first engaging portion 941 and the second engaging portion 942 can be other types of engaging portions, such as toothed engaging portions, as long as they can be drivingly engaged with each other to drive the plug 910 to move.

[0199] In some embodiments, as Figure 11C As shown, the first engaging portion 941 is fixedly connected to the plug 910, for example, via a connector 943. However, the present invention is not limited thereto. In some embodiments, the first engaging portion 941 and the plug 910 are independent components. For example, the plug 910 can be movably supported by the first engaging portion 941 (for example, via a connector 943) and move with the movement of the first engaging portion 941.

[0200] In some embodiments, as Figure 11C As shown, the second engaging portion 942 is integrally formed with the output shaft 931 of the motor 930, i.e., the second engaging portion 942 is an external thread formed on the output shaft 931. However, the present invention is not limited to this. In some embodiments, the second engaging portion 942 and the output shaft 931 can be formed separately and fixedly connected together. For example, the second engaging portion 942 and the output shaft 931 can be connected to each other by an adhesive, threads, etc.

[0202] According to certain embodiments of the present invention, the ventilation volume regulating device 400 can regulate the ventilation volume of the ventilation channel by driving the plug 910 to move relative to the plug seat 920 via the motor 930. Specifically, when the motor 930 is energized, the output shaft 931 and the second engaging portion 942 of the motor 930 rotate, thereby driving the first engaging portion 941 and the plug 910 to move relative to the plug seat 920, so that the plug 910 is inserted into or removed from the plug seat 920, thereby opening or closing the ventilation channel or regulating the degree of opening of the ventilation channel.

[0203] In some embodiments, as Figure 11H As shown, when ventilation of the ventilation channel is achieved, the plug 910 can be driven by the motor 930 to partially move out of the plug seat 920 without having to move it completely out of the plug seat 920. Thus, in the process of gradually moving the plug 910 out of the plug seat 920, the plug 910 can be maintained at different positions relative to the plug seat 920, thereby achieving different degrees of ventilation. In some embodiments, as shown in FIG. Figure 11E 、 Figure 11G and Figure 11H As shown, the plug 910 includes a limiting portion 912, and the plug seat 920 includes a corresponding limiting portion 922. Thus, through the cooperation of the limiting portions 912 and 922, the plug 910 can be limited to different positions relative to the plug seat 920, thereby making it easier to achieve different degrees of ventilation.

[0204] The above description describes that the ventilation volume regulating device 400 having a plug-type structure according to certain embodiments of the present invention includes a separate plug seat 920. However, the present invention is not limited thereto. In some embodiments, the plug seat can be formed by the customized housing 100. In an exemplary embodiment, the plug seat and the customized housing 100 are integrally formed. The plug member 910 can be inserted into or removed from the plug seat formed by the customized housing 100.

[0205] It is described above that the plug 910 of the ventilation volume regulating device 400 according to some embodiments of the present invention is configured to be inserted into or removed from the plug seat 920.

When the motor 930 is energized, the output shaft 931 and the second engaging portion 942 of the motor 930 rotate, thereby driving the first engaging portion 941 and the plug 910 to move relative to the plug seat 920, so that the plug 910 moves away from or approaches the plug seat 920, thereby opening or closing the ventilation channel or adjusting the degree of opening of the ventilation channel.

[0206] The above description shows that the movement direction of the plug 910 is substantially parallel to the extension direction of the vent hole 300 at the ventilation volume regulating device 400.
