Description

Technical Field

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

[0002] In the field of biomedical signal processing, PPG (Photoplethysmogram) sensor technology is an important non-invasive monitoring technology, widely used in heart rate monitoring, blood oxygen saturation measurement, and other fields. Currently, many companies are beginning to integrate PPG sensors into wearable ear devices to achieve real-time monitoring of human health.

[0003] However, current ear wearable devices equipped with PPG sensors generally use standard-sized ear wearable device shells and standard-sized PPG sensors manufactured using common molds. Since the shape of each person's ear is different, it is difficult to ensure that the PPG sensor has good contact with each person's ear. The contact between the PPG sensor and the ear has an important impact on the accuracy and consistency of the measurement results. Utility Model Content

[0004] Therefore, it is necessary to provide an ear-wearable device in which the optical sensors can make good contact with each user's ear.

[0005] In a first aspect, an ear-wearable device is provided, comprising:

[0006] The housing includes a main body and a sub-housing, the area of ​​the sub-housing that contacts the user's ear having an opening; wherein, the opening includes a transmitting window and a receiving window;

[0007] Light-emitting devices are used to emit light through an emission window;

[0008] A light-receiving device, used to receive light through a receiving window;

[0009] A partition is located between the transmitting window and the receiving window, and at least part of the partition is located within the opening; the partition is used to optically isolate the light-emitting device and the light-receiving device; wherein the partition has a distal end exposed to the outer surface of the sub-housing, and the shapes of the outer surface of the sub-housing and the distal end of the partition are customized according to the shape of the ear.

[0010] In one embodiment, the housing and the partition are customized to the shape of the user's ear; and / or, the housing and the partition are manufactured using a one-piece molding process.

[0011] In one embodiment, the opening of the sub-shell contacts at least a portion of the tragus and / or the antitragus.

[0012] In one embodiment, the above-mentioned ear-wearing device further includes:

[0013] A first transparent element is disposed within the transmission window;

[0014] A second transparent element is disposed within the receiving window;

[0015] The distal ends of both the first and second transparent elements are matched to the shape of the user's ear.

[0016] In one embodiment, the first transparent element is formed by injecting a first light-transmitting material into the transmitting window, and / or the second transparent element is formed by injecting a second light-transmitting material into the receiving window.

[0017] In one embodiment, the first inner wall of the sub-shell and the second inner wall of the partition enclose a emission window, and the first inner wall and / or the second inner wall are provided with a light-blocking material; and / or

[0018] The third inner wall of the sub-shell and the fourth inner wall of the partition enclose a receiving window, and the third inner wall and / or the fourth inner wall are provided with light-blocking material.

[0019] In one embodiment, the sub-shell has an inner surface disposed opposite to the outer surface, the partition has a proximal end disposed opposite to the distal end, and the inner surface of the sub-shell and / or the proximal end of the partition is coated with a light-blocking material.

[0020] In one embodiment, the outer surfaces of both the first transparent element and the second transparent element are covered with transparent paint.

[0021] In one embodiment, the sub-shell protrudes relative to the body.

[0022] In one embodiment, the sub-shell is flush with the body.

[0023] The aforementioned ear-wearable device includes a housing, a light-emitting device, a light-receiving device, and a partition for optically isolating the light-emitting and light-receiving devices. The housing comprises a main body and a sub-housing. The area of ​​the sub-housing that contacts the user's ear has an opening containing a transmitting window and a receiving window. The partition is at least partially located within the opening. The outer surface of the sub-housing and the distal end of the partition are custom-designed to fit the shape of the ear, ensuring that the outer surface of the sub-housing and the distal end of the partition almost perfectly match the actual contour of the user's ear. This allows the optical sensor (which includes at least a light-emitting device and a light-receiving device) to effectively isolate the light-emitting and light-receiving devices.

The outer surface of the sub-shell is customized according to the shape of the ear, so that the outer contours of the transmitting and receiving windows have good and stable contact with the ear, which can prevent the light emitted by the light-emitting device from leaking into the external environment. In particular, the distal end of the partition is also customized according to the shape of the ear, and the distal end of the partition has good and stable contact with the ear, which prevents the light emitted by the light-emitting device from being directly received by the light-receiving device without being reflected by the human skin, thereby helping to obtain more accurate health data.

[0035] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] It is understandable that "at least one pair" refers to one or more pairs, while "more than one pair" refers to two or more pairs. "At least part of an element" refers to part or all of an element.

[0038] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, an ear-wearing device 10 is provided, including: a housing 102, a light-emitting device 104, a light-receiving device 106, and a partition 108.

[0040] The housing 102 includes a main body 1022 and a sub-housing 1024. The area of ​​the sub-housing 1024 that contacts the user's ear has an opening. The opening includes a transmitting window 202 and a receiving window 204.

[0041] The light-emitting device 104 is used to emit light through the emission window 202.

[0042] The light-receiving device 106 is used to receive light through the receiving window 204. The light-emitting device 104 can be the light-emitting device 104 of an optical sensor, and correspondingly, the light-receiving device 106 can be the light-receiving device 106 of an optical sensor.

[0043] For example, an optical sensor may include a light-emitting device 104, a light-receiving device 106, a transmitting window 202, a receiving window 204, a partition 108, and at least a portion of a sub-housing 1024.

[0044] For example, the optical sensor can be a photoplethysmography (PPG) sensor.

[0045] For example, the ear wearable device 10 includes, but is not limited to, devices that can be worn on the ear such as headphones, hearing aids, cochlear implants, and bone conduction devices. This application does not impose specific limitations on the ear wearable device 10. In addition, the ear wearable device 10 includes, but is not limited to, behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), in-the-canal (IIC), in-the-canal receiver (RIC), ear receiver (RITE), or completely in-the-canal (CIC) devices, or some combination of the above devices.

[0046] For example, headphones include, but are not limited to, in-ear headphones, semi-in-ear headphones, ear-hook headphones, open-back headphones, over-ear headphones, clip-on headphones, and neckband headphones. Headphones can be air conduction headphones, bone conduction headphones, or a combination of both. Headphones can be custom-made or non-custom-made.

[0047] The partition 108 is located between the transmitting window 202 and the receiving window 204; the partition 108 is used to optically isolate the light-emitting device 104 and the light-receiving device 106; wherein, the partition 108 has a distal end exposed to the outer surface of the sub-housing 1024, and the shape of the outer surface of the sub-housing 1024 and the distal end of the partition 108 are customized according to the shape of the ear.

[0048] The partition 108 is located between the transmitting window 202 and the receiving window 204, so that the transmitting window 202 and the receiving window 204 are non-connected structures, the light from the two windows does not interfere with each other, and the light emitted by the light-emitting device 104 from the transmitting window 202 is reflected by the ear and projected onto the receiving window 204 so that the light-receiving device 106 can receive the light.

[0049] When a user wears the ear-wearing device 10, the outer surface of the sub-shell 1024 and the distal end of the partition 108 are in contact with the ear, so that the light-emitting device 104 is reflected by the ear and received by the light-receiving device 106. Therefore, the shape of the outer surface of the sub-shell 1024 and the distal end of the partition 108 in contact with which part of the ear can be customized according to the shape of the ear at that part.

[0050] The outer surface of the sub-shell 1024 and the shape of the distal end of the partition 108 are customized according to the shape of the ear. Optionally, the user's ear model can be obtained first through 3D scanning technology, multi-view photogrammetry, ultrasound imaging, computed tomography, or printed ear molds. Then, the shape of the outer surface of the sub-shell 1024 and the shape of the distal end of the partition 108 can be designed specifically according to the ear model, so that the curvature of this part uniquely matches the curvature of the user's ear, achieving unique customization for each user. The ear wearable device 10 obtained based on this design can ensure that the user's ear can completely fit the outer contour of the transmitting window 202 and the outer contour of the receiving window 204. This avoids the situation where the light emitted by the light-emitting device 104 is received by the light-receiving device 106 without being reflected by the skin when the optical sensor of the ear wearable device 10 does not fit the curvature of the ear, thus preventing light crosstalk. This ensures that the light received by the light-receiving device 106 is all light reflected by the user's skin, improving the detection accuracy of the ear wearable device 10.

[0051] The aforementioned ear-wearing device 10 includes a housing 102, a light-emitting device 104, a light-receiving device 106, and a partition 108 for optically isolating the light-emitting device 104 and the light-receiving device 106. The housing 102 includes a main body 1022 and a sub-housing 1024. The area of ​​the sub-housing 1024 that contacts the user's ear has an opening, which includes a transmitting window 202 and a receiving window 204. The partition 108 is at least partially located within the opening. The outer surface of the sub-housing 1024 and the distal end of the partition 108 are custom-made to fit the shape of the ear, making the outer surface of the sub-housing 1024 and the distal end of the partition 108 almost perfectly match the actual contour of the user's ear, thereby enabling the optical sensor (which at least includes...) to... The light-emitting device 104, the light-receiving device 106, the partition 108, and at least part of the sub-housing 1024 have good contact with each user's ear, which is beneficial to improving the measurement accuracy of the optical sensor. The outer surface of the sub-housing 1024 is customized according to the shape of the ear, so that the outer contours of the transmitting and receiving windows have good and stable contact with the ear, which can prevent the light emitted by the light-emitting device 104 from leaking into the external environment. In particular, the distal end of the partition 108 is also customized according to the shape of the ear, and the distal end of the partition 108 has good and stable contact with the ear, which prevents the light emitted by the light-emitting device 104 from being directly received by the light-receiving device 106 without being reflected by the human skin, thereby facilitating the acquisition of more accurate health data.

[0052] In one embodiment, the shape of the outer surface of the sub-shell 1024 and the shape of the distal end of the partition 108 can determine a smooth, conforming arc to the curvature of the user's ear. The smooth arc design can improve the wearing comfort and fit of the ear wearable device 10.

[0053] In one embodiment, there may be multiple openings on the sub-housing 1024, thereby opening multiple pairs of transmitting windows 202 and receiving windows 204 to set up multiple sets of light-emitting devices 104 and light-receiving devices 106, realize multi-point measurement, and thereby improve the monitoring accuracy of physiological parameters of the ear wearable device 10.

[0054] In one embodiment, the barrier 108 is made of a non-transparent material to improve the light blocking effect between the transmitting window 202 and the receiving window 204, thereby improving the measurement accuracy of the ear-wearing device 10.

[0055] In one embodiment, the width of the partition 108 can be greater than or equal to 0.5 mm, such as 0.5 mm, 1 mm, 2 mm, 5 mm, etc. This size design can improve the isolation effect between the light output by the light-emitting device 104 and the light received by the light-receiving device 106.

[0056] In one embodiment, the shape of the distal end of the spacer 108 conforms to the curvature of the user's ear, providing support and thus improving the user's wearing comfort.

[0057] In one embodiment, the optical sensor includes a sub-housing 1024, a light-emitting device 104, a light-receiving device 106, and a partition 108.

[0058] In one embodiment, the housing 102 and the partition 108 are customized according to the shape of the user's ear; and / or, the housing 102 and the partition 108 are manufactured using a one-piece molding process.

[0059] The shell and partition can be made of the same material, which can be a material suitable for 3D printing. This material can be photosensitive resin or other polymer materials, or it can be metal or dental materials. Dental materials can be denture base resin. This is just an example, and this application does not impose any special restrictions on the materials of the shell and partition.

[0060] The light emitted by the light-emitting device 104 is reflected by the skin and received by the light-receiving device 106. The housing 102 and the partition 108 are both customized according to the shape of the user's ear to ensure that the entire housing 102 and the partition 108 fit the user's ear perfectly. This ensures that the optical path of the optical sensor is consistent and the measurement accuracy is high when different users wear the ear wearable device in different scenarios (sitting, lying down or exercising, etc.).

[0061] More specifically, because the shell 102 is custom-designed for the user, it exerts virtually no pressure on the user's ear. Therefore, compared to a standard-sized shell 102, the ear-wearing device 10 of this invention offers superior wearing comfort. Furthermore, since the shell 102 is custom-designed for the user, it fits better with the user's ear (e.g., external auditory canal, concha, cymba conchae, tragus, and / or antitragus), ensuring a secure fit and preventing it from easily falling off. With both excellent comfort and secure fit, users can wear the ear-wearing device for longer periods and in various scenarios (sitting, lying down, or exercising, etc.). In other words, since the housing 102 is customized according to the shape of the user's ear, it ensures both comfort and stability for different users wearing the ear-worn device in various scenarios, and also ensures good contact between the ear-worn device and the user's ear. The sub-housing 1024 is a part of the housing 102. Since the housing 102 is customized according to the shape of the ear, the sub-housing 1024 is also customized according to the shape of the ear. The area of ​​the sub-housing 1024 that contacts the user's ear has an opening, which includes a transmitting window 202 and a receiving window 204. The partition 108 is at least partially located within the opening. The sub-housing 1024 is equivalent to the housing of the optical sensor. The body 102 and the sub-shell 1024 are customized according to the shape of the ear. This means that the housing 102 of the optical sensor is customized according to the shape of the ear, so that the outer contour of the optical sensor (i.e. the outer surface of the sub-shell 1024) forms a stable and good contact with the user's ear, which can prevent the light emitted by the light-emitting device 104 from leaking into the external environment. At the same time, the barrier 108 is also customized according to the shape of the ear. The distal end of the barrier 108 has a good and stable contact with the ear, which prevents the light emitted by the light-emitting device 104 from being directly received by the light-receiving device 106 without being reflected by the user's ear skin, thereby facilitating the acquisition of more accurate health data.

[0062] In summary, both the housing 102 and the partition 108 are customized according to the shape of the user's ear. Both the entire ear-wearing device (mainly referring to the housing 102) and the optical sensor (mainly referring to the outer surface of the sub-housing 1024 and the distal end of the partition 108) have stable and good contact with the user's ear, and the wearing comfort is high. Regardless of whether the user is sitting, lying down, exercising, or in other states, or whether different users are wearing the ear-wearing device, it can prevent the optical sensor from leaking light into the external environment, and also prevent the light emitted by the light-emitting device 104 from being directly received by the light-receiving device 106 without being reflected by the human skin. The consistency of the optical path is good, and the measurement accuracy of the optical sensor is high.

[0063] The shell 102 and the partition 108 are manufactured using a one-piece molding process, which is simpler and more convenient. This process allows the shell 102 and the partition 108 to be seamlessly connected, resulting in smooth lines. In particular, the outer surface of the shell 102 and the far end of the partition 108 can also maintain their smooth line design, thereby improving the comfort and stability of wearing. It is understood that the partition 108 can be part of the housing 102. In this embodiment, for functional differentiation, the housing 102 and the partition 108 are named separately. The housing 102 includes a sub-housing 1024. When the partition 108 is part of the housing 102, it is equivalent to the sub-housing 1024 and the partition 108 of the optical sensor being part of the housing 102. At this time, the housing 102 is manufactured using an integral molding process, which also yields the sub-housing 1024 and the partition 108 of the optical sensor, greatly simplifying the manufacturing process. In particular, when the housing 102 is customized according to the shape of the ear, a customized sub-housing 1024 and the partition 108 can be obtained. This is equivalent to the outer contour of the optical sensor and the far end of the partition being customized according to the shape of the ear. The manufacturing process is simple, and it ensures stable and good contact between the ear-wearing device and the optical sensor and the user's ear, resulting in good consistency of the optical path of the optical sensor and high optical measurement accuracy.

[0064] Of course, the partition 108 may not be part of the shell 102. The partition 108 and the shell 102 may be prepared separately and then combined together by certain technical means.

[0065] When a user wears the ear-wearing device 10, the opening of the sub-shell 1024 can come into contact with the concha cavity, cymba conchae, tragus and / or antitragus. That is, the optical sensor can come into contact with the concha cavity, cymba conchae, tragus and / or antitragus. The above is just an example. This application does not impose specific restrictions on the area in which the opening of the sub-shell 1024 contacts the ear.

[0066] In one embodiment, the opening of the sub-shell 1024 contacts at least a portion of the tragus and / or the antitragus.

[0067] like Figure 3 As shown, the tragus is Figure 3 Position A in the diagram. For example... Figure 4 As shown, the tragus is Figure 4 Position B in the diagram.

[0068] The opening of the sub-housing 1024 contacting at least a portion of the tragus and / or antitragus means that when the user is normally wearing the ear-wearing device 10, the transmitting window 202 and the receiving window 204 are in contact with at least a portion of the user's tragus and / or antitragus. In one embodiment, the opening of the sub-housing 1024 contacts at least a portion of the tragus. In another embodiment, the opening of the sub-housing 1024 contacts at least a portion of the antitragus. In yet another embodiment, the opening of the sub-housing 1024 may contact both the tragus and the antitragus. In this case, there are multiple openings, and multiple sets of light-emitting devices 104 and light-receiving devices 106, allowing for multi-point monitoring of the user's physiological parameters.

[0069] The tragus and antitragus are areas in the human ear with a high density of blood vessels. Therefore, the light-emitting device 104 and the light-receiving device 106 transmit and receive light in the area in contact with the tragus and / or antitragus, which enables non-invasive and convenient monitoring of physiological parameters, obtains more accurate pulse waveforms and heart rate, and thus improves the monitoring accuracy of the ear wearable device 10.

[0070] In one embodiment, such as Figure 5 As shown, the above-mentioned ear-wearing device 10 also includes: a first transparent element 502 and a second transparent element 504.

[0071] The first transparent element 502 is disposed within the emission window 202. At least a portion of the first transparent element 502 is located above the light-emitting device 104.

[0072] The second transparent element 504 is disposed within the receiving window 204. At least a portion of the second transparent element 504 is located above the light receiving device 106.

[0073] The distal ends of the first transparent element 502 and the second transparent element 504 are both matched to the shape of the user's ear. The distal end of the first transparent element 502 refers to the end of the first transparent element 502 that contacts or is close to the human ear, and the distal end of the second transparent element 504 refers to the end of the second transparent element 504 that contacts or is close to the human ear.

[0074] The first transparent element 502 can protect the light-emitting device 104 built into the ear wearable device 10, and the second transparent element 504 can protect the light-receiving device 106 built into the ear wearable device 10, so that the optical sensor forms a sealed whole, thereby achieving the effect of dustproof and waterproof, and extending the service life of the ear wearable device 10.

[0075] Furthermore, the light emitted by the light-emitting device 104 is projected onto the user's skin through the transparent first transparent element 502, and the light reflected by the user's skin is projected onto the light-receiving device 106 through the second transparent element 504. This can improve the light coupling effect, thereby reducing the degree of distortion of the monitoring data and improving the reliability of the monitoring.

[0076] The outer surface of the sub-housing 1024, the distal end of the partition 108, the distal end of the first transparent element 502, and the distal end of the second transparent element 504 all match the shape of the user's ear. This allows the optical sensor in the areas of the transmitting window 202 and the receiving window 204 to fit more closely to the user's ear, thereby reducing light leakage and ensuring the correct light transmission path. At this point, the outer surface of the sub-housing 1024, the distal end of the partition 108, the distal end of the first transparent element 502, and the distal end of the second transparent element 504 all match the shape of the user's ear, which helps to further improve measurement accuracy.

[0077] It should be noted that the first transparent element 502 does not refer only to visually transparent elements, but rather to elements with a light transmittance greater than or equal to 10%, such as elements with light transmittance of 20%, 35%, 87%, 100%, etc. These elements can all be considered as the first transparent element 502; that is, any element with a light transmittance between 10% and 100% can be regarded as the first transparent element 502. Correspondingly, the second transparent element 504 has the same setting requirements as the first transparent element 502, which will not be elaborated here.

[0078] Preferably, both the first transparent element 502 and the second transparent element 504 are elements with a light transmittance of 90% or higher.

[0079] Preferably, the first transparent element 502 and the second transparent element 504 can have high transmittance for light within a specific wavelength range, without considering the transmittance of light within other wavelength ranges. The specific wavelength range can be determined based on the wavelengths of light emitted and received by the optical sensor of the ear-wearing device 10.

[0080] In one embodiment, the first transparent element 502 and the second transparent element 504 are independently molded elements, which are then placed in the transmitting window 202 and the receiving window 204.

[0081] In one embodiment, the first transparent element 502 is formed by filling the transmitting window 202 with a first light-transmitting material, and / or the second transparent element 504 is formed by filling the receiving window 204 with a second light-transmitting material.

[0082] The first and second light-transmitting materials can be the same material or different materials. Preferably, the first and second light-transmitting materials are the same material. When filling the transmitting window 202 and receiving window 204 with light-transmitting material, the operation is simple and there is no need to change the light-transmitting material.

[0083] like Figure 2 and Figure 5As shown, the ear-wearing device 10 also includes a circuit board 200, and a light-emitting device 104 and a light-receiving device 106 are both disposed on the circuit board 200. A first transparent element 502 covers the light-emitting device 104 above the circuit board 200, and a second transparent element 504 covers the light-receiving device 106 above the circuit board 200.

[0084] Since the outer surface of the sub-shell 1024 of the optical sensor and the shape of the distal end of the partition 108 are customized according to the shape of the ear, the shapes of the transmitting window 202 and the receiving window 204 of different ear-wearing devices 10 are different. It is difficult to adapt the first transparent element 502 and the second transparent element 504 of standard size to different ear-wearing devices 10. The cost of using customized first transparent element 502 and second transparent element 504 is too high. Instead, a first light-transmitting material is injected into the transmitting window 202 and a second light-transmitting material is injected into the receiving window 204 so that the first light-transmitting material and the second light-transmitting material can be solidified in the shape of the transmitting window 202 and the receiving window 204, respectively. This ensures the matching degree between the first transparent element 502 and the transmitting window 202 and the matching degree between the second transparent element 504 and the receiving window 204. On the one hand, the process is simple and the cost is low. On the other hand, the first and second light-transmitting materials can be injected to be basically flush with the outer surface of the sub-shell 1024 and the far end of the partition 108. Since the shape of the outer surface of the sub-shell 1024 and the far end of the partition 108 are customized according to the shape of the ear, the far ends of the first transparent element 502 and the far ends of the second transparent element 504 also match the shape of the user's ear. At this time, the outer surface of the sub-shell 1024 of the optical sensor, the far end of the partition 108, the far end of the first transparent element 502 and the far end of the second transparent element 504 all match the shape of the user's ear and have stable and good contact, which can ensure the measurement accuracy of different users and different scenarios (sitting, lying down or exercising, etc.).

[0085] In one embodiment, both the first and second light-transmitting materials are transparent resins.

[0086] In one embodiment, the circuit board 200 is fixed to the housing 102 by means of adhesive backing, clips, etc.

[0087] The adhesive backing and snap-fit ​​design allow the optical sensor to be securely fixed inside the housing 102, reducing sensor movement and thus improving user comfort and measurement accuracy.

[0088] In one embodiment, the first inner wall 302 of the sub-shell 1024 and the second inner wall 304 of the partition 108 enclose and form a transmission window 202, and the first inner wall 302 and / or the second inner wall 304 are provided with light-blocking material.

[0089] And / or,

[0090] The third inner wall 306 of the sub-shell 1024 and the fourth inner wall 308 of the partition 108 enclose and form a receiving window 204, and the third inner wall 306 and / or the fourth inner wall 308 are provided with light-blocking material.

[0091] Specifically, such as Figure 6 The green area shown and Figure 7 The green area shown (but it should be understood that the figure is intended to show the location of the light-blocking material coating, but does not limit the color of the light-blocking material to green) is the area where the aforementioned light-blocking material is applied.

[0092] The use of light-blocking material can prevent light from leaking directly from the transmitting window 202 to the receiving window 204, so that the light receiving device 106 can directly receive the leaked light without skin reflection, thereby improving the monitoring accuracy of the ear wearable device 10.

[0093] Furthermore, light-blocking material can be provided only on the first inner sidewall 302 and the second inner sidewall 304, or only on the second inner sidewall 304, or only on the third inner sidewall 306 and the fourth inner sidewall 308, or only on the fourth inner sidewall 308, or only on the second inner sidewall 304 and the fourth inner sidewall 308. These embodiments help reduce process complexity and the cost of light-blocking materials. Alternatively, light-blocking material can be provided on the first inner sidewall 302 and the second inner sidewall 304, and on the third inner sidewall 306 and the fourth inner sidewall 308, which helps improve the light-blocking effect.

[0094] In one embodiment, the light-blocking material includes at least one of light-blocking ink, a metal layer deposited by metal physical vapor deposition, and a light-blocking sticker.

[0095] Light-blocking inks, metal layers deposited by physical vapor deposition, and light-blocking stickers can effectively improve light-blocking performance, thereby enhancing the measurement accuracy of optical sensors.

[0096] In one embodiment, the sub-housing 1024 has an inner surface disposed opposite to the outer surface, and the partition 108 has a proximal end disposed opposite to the distal end. The outer surface and the distal end are the ends of the optical sensor that contact or are close to the ear, and the inner surface and the proximal end are the ends that are far from the ear. The inner surface of the sub-housing 1024 and / or the proximal end of the partition 108 are coated with a light-blocking material.

[0097] like Figure 8 The green area shown is the area where the aforementioned light-blocking material is coated.

[0098] The light-blocking material disposed on the inner surface of the sub-housing 1024 and / or near the end of the partition 108 can prevent light from leaking directly from the transmitting window 202 into the receiving window 204, so that the light receiving device 106 can directly receive the leaked light without skin reflection, thereby improving the light blocking effect and thus improving the measurement and monitoring accuracy of the optical sensor of the ear wearable device 10.

[0099] In one embodiment, the outer surfaces of the first transparent element 502 and the second transparent element 504 are both covered with transparent paint.

[0100] After the first transparent element 502 and the second transparent element 504 are injected, the outer surfaces of the first transparent element 502 and the second transparent element 504 can be polished first, and then transparent paint can be applied to the outer surfaces of the first transparent element 502 and the second transparent element 504 to improve the light transmission efficiency of the light-emitting device 104 and the light-receiving device 106 as well as the appearance of the ear wearable device 10.

[0101] The aforementioned transparent paint can be UV oil (UV Curing Ink, UV Coating, or UV coating), or of course, other types of transparent paint.

[0102] In one embodiment, the outer surface of the sub-housing 1024 and / or the distal end of the partition 108 may be coated with a transparent paint to enhance the appearance of the ear-wearing device 10.

[0103] In one embodiment, the sub-housing 1024 protrudes relative to the main body 1022.

[0104] like Figure 9 As shown, the sub-shell 1024 protrudes from the main body 1022, which allows the sub-shell 1024 to apply a certain contact pressure to the ear, so that the wearer's ear fits the sub-shell 1024 more closely in different scenarios (sitting, lying down, or exercising, etc.), thereby ensuring that the optical sensor fully contacts the ear skin and improves detection accuracy.

[0105] Furthermore, to improve user comfort when wearing the ear-worn device 10, the protrusion of the sub-shell 1024 relative to the main body 1022 can be any value less than or equal to 2.5 mm and greater than 0. For example, it can be 0.5 mm, 1 mm, 2 mm, or 2.5 mm. This protrusion distance, within 2.5 mm, ensures that the optical sensor makes full contact with the ear skin while avoiding excessive pressure from the optical sensor on the ear skin, thus preventing pain for the user.

[0106] In one embodiment, the sub-shell 1024 is flush with the body 1022.

[0107] like Figure 10 As shown, the sub-shell 1024 is flush with the main body 1022. Since the sub-shell 1024 is customized according to the shape of the ear, it can ensure that the outer surface of the sub-shell 1024 has good contact with the user's ear, and reduce the presence of the sub-shell 1024. This prevents the wearer from experiencing pain or even leaving marks due to the sub-shell 1024 when wearing the ear wearable device 10 for a long time, thereby increasing the user's wearing comfort.

[0108] In one embodiment, the housing 102 is made of a light-transmitting material.

[0109] The housing 102 can be designed with a light-transmitting material to improve the appearance of the ear wearable device 10 and enhance its visual appeal.

[0110] Furthermore, after polishing, the housing 102 is coated with transparent paint to further enhance the appearance of the ear-wearing device 10.

[0111] The first inner wall 302 of the sub-shell 1024 and the second inner wall 304 of the partition 108 enclose and form a transmitting window 202. The third inner wall 306 of the sub-shell 1024 and the fourth inner wall 308 of the partition 108 enclose and form a receiving window 204. It should be noted that, in order to ensure the detection performance of the ear-wearable device 10, if the shell 102 is made of a light-transmitting material, light-blocking materials need to be provided on the first inner wall 302 and the third inner wall 306, and light-blocking materials need to be provided on at least one inner wall of the second inner wall 304 and the fourth inner wall 308, so as to prevent the light emitted by the light-emitting device 104 from directly entering the internal space of the shell 102 without being reflected by the user's ear or being directly received by the light-receiving device 106 without being reflected by the user's ear.
