[0061] In the field of biomedical signal processing, PPG (Photo Plethysmo Gram) sensor technology is an important non-invasive monitoring technology, which is widely used in heart rate monitoring, blood oxygen saturation measurement and other fields. At present, many companies have begun to integrate PPG sensors into ear-wearable devices to realize real-time monitoring of human health status.

[0062] However, the current ear-wearable devices equipped with PPG sensors generally use standard size ear-wearable device shells and standard size PPG sensors prepared by public 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, and the contact between the PPG sensor and the ear has an important influence on the accuracy and consistency of the measurement results.

[0063] To this end, embodiments of the present application provide an ear-wearable device and a manufacturing method thereof, the optical sensor of the ear-wearable device can have good contact with each user's ear. Some embodiments will be described below in conjunction with the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0064] As shown in FIG. 1 and FIG. 2, an ear-wearable device 10 is provided, comprising a housing 102 and an optical sensor. The housing 102 comprises a main body 1022 and a sub-housing 1024, the area of the sub-housing 1024 in contact with the user's ear has an opening; the opening comprises an emission window 202 and a receiving window 204, the optical sensor can comprise a light emitting device 104 and a light receiving device 106.

[0065] In some embodiments, the light emitting device 104 is used to emit light through the emission window 202. 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 the optical sensor, and correspondingly, the light receiving device 106 can be the light receiving device 106 of the optical sensor.

[0066] Illustratively, the optical sensor can be a photoplethysmographic sensor, i.e. a PPG sensor.

[0067] Illustratively, the ear-wearable device 10 includes but is not limited to a device that can be worn on the ear, such as a headset, a hearing aid, a cochlear implant, and a bone conduction device, etc. The present application does not make specific limitations to the ear-wearable device 10. In addition, the ear-wearable device 10 includes but is not limited to a behind-the-ear (BTE), an in-the-ear (ITE), an in-the-canal (ITC), an invisible in-the-canal (IIC), a receiver-in-the-canal (RIC), a receiver-in-the-ear (RITE), or a completely-in-the-canal (CIC) type device or some combination of the above devices.

[0068] Illustratively, the headset includes but is not limited to an in-ear headset, a semi-in-ear headset, an over-ear headset, an open ear headset, a headset, a clip-on headset, a neckband headset, the headset can be an air conduction headset, a bone conduction headset or a combination of the two. The headset can be a custom-made headset or a non-custom-made headset.

[0069] In some embodiments, the optical sensor can further comprise a barrier 108. The barrier 108 is located between the emission window 202 and the receiving window 204; the barrier 108 is used to optically isolate the light emitting device 104 and the light receiving device 106; wherein the barrier 108 has a distal end exposed to the outer surface of the sub-housing 1024, the shape of the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are customized according to the shape of the ear.

[0070] In some embodiments, the barrier 108 is located between the emission window 202 and the receiving window 204, so that the emission window 202 and the receiving window 204 are non-communicating structures, the light emitted from the emission window 202 and the light received by the receiving window 204 do not interfere with each other, and the light emitted by the light emitting device 104 from the emission window 202 is reflected by the ear and projected to the receiving window 204 so as to be received by the light receiving device 106.

[0071] In some embodiments, when the user wears the ear-wearing device 10, the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are in contact with the ear, so that the light emitted by the light emitting device 104 is received by the light receiving device 106 after being reflected by the ear. Therefore, the shape of the outer surface of the sub-housing 1024 and the distal end of the barrier 108 can be customized according to the shape of the ear.

[0072] In some embodiments, the shape of the outer surface of the sub-housing 1024 and the distal end of the barrier 108 is customized according to the shape of the ear. Optionally, the ear model of the user can be obtained by 3D scanning technology, multi-view photogrammetry, ultrasonic imaging, computed tomography, ear mold printing, etc. Then, the shape of the outer surface of the sub-housing 1024 and the shape of the distal end of the barrier 108 are designed according to the ear model, so that the shape of this part is uniquely matched with the curvature of the user's ear, and the customization for each user is realized. The ear-wearing device 10 designed in this way can ensure that the user's ear can completely fit the outer contour of the emission window 202 and the outer contour of the receiving window 204, and avoid the situation that the optical sensor of the ear-wearing device 10 does not fit the curvature of the ear, and the light emitted by the light emitting device 104 is received by the light receiving device 106 without being reflected by the skin, resulting in light interference. Therefore, it is ensured that the light received by the light receiving device 106 is all the light reflected by the user's skin, and the detection accuracy of the ear-wearing device 10 is improved.

[0073] The ear-wearable device 10 includes a housing 102, a light emitting device 104, a light receiving device 106, and a barrier 108 for optically isolating the light emitting device 104 and the light receiving device 106, wherein the housing 102 includes a main body 1022 and a sub-housing 1024, the area of the sub-housing 1024 in contact with the user's ear has an opening, the opening includes an emission window 202 and a receiving window 204, the barrier 108 is at least partially located in the opening, the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are shaped according to the shape of the ear, so that the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are almost completely consistent with the actual contour of the user's ear, so that the optical sensor (the optical sensor at least includes the light emitting device 104 and the light receiving device 106, the barrier 108, and at least part of the sub-housing 1024) has good contact with each user's ear, which helps to improve the measurement accuracy of the optical sensor, wherein the outer surface of the sub-housing 1024 is shaped according to the shape of the ear, so that the outer contour of the emission window and the receiving window has good and stable contact with the ear, and the light emitted by the light emitting device 104 can be prevented from leaking to the external environment, in particular, the distal end of the barrier 108 is also shaped according to the shape of the ear, and the distal end of the barrier 108 has good and stable contact with the ear, so that the light emitted by the light emitting device 104 is not directly received by the light receiving device 106 without being reflected by the human skin, thereby helping to obtain more accurate health data.

[0074] In some embodiments, the shape of the outer surface of the sub-housing 1024 and the shape of the distal end of the barrier 108 can determine a smooth arc that fits the curvature of the user's ear. With the design of the smooth arc, the wearing comfort and the wearing fit of the ear-wearable device 10 can be improved.

[0075] In some embodiments, there can be multiple openings on the sub-housing 1024, thereby forming multiple pairs of emission windows 202 and receiving windows 204 to set multiple groups of light emitting devices 104 and light receiving devices 106, so as to realize multi-point measurement and improve the monitoring accuracy of the ear-wearable device 10 on physiological parameters.

[0076] In some embodiments, the barrier 108 is made of a non-light-transmitting material to improve the light isolation effect between the emission window 202 and the receiving window 204, thereby improving the measurement accuracy of the ear-wearable device 10.

[0077] In some embodiments, the width of the barrier 108 can be greater than or equal to 0.5 mm, such as 0.5 mm, 1 mm, 2 mm, 5 mm, etc. With this size design, the isolation effect between the light output by the light emitting device 104 and the light received by the light receiving device 106 can be improved.

[0078] In some embodiments, the shape of the distal end of the barrier 108 fits the curvature of the user's ear, and can serve as a support, thereby improving the user's wearing comfort.

[0079] In some embodiments, the optical sensor includes the sub-housing 1024, the light emitting device 104, the light receiving device 106, and the barrier 108.

[0080] In some embodiments, the housing 102 and the barrier 108 are customized according to the shape of the user's ear; and / or, the housing 102 and the barrier 108 are made by an integral molding process.

[0081] In some embodiments, the housing and the barrier can be made of the same material, which can be a material suitable for 3D printing, such as a photosensitive resin or other polymer material, a metal, or a dental material, which can be a denture base resin. This is just an example, and the present application does not particularly limit the material of the housing and the barrier.

[0082] In some embodiments, the light emitted by the light emitting device 104 is received by the light receiving device 106 after being reflected by the skin, and the housing 102 and the barrier 108 are customized according to the shape of the user's ear, which can ensure that the entire housing 102 and the barrier 108 perfectly fit the user's ear, so that the optical sensor has good consistency of the light path and high measurement accuracy when the ear-wearing device is worn by different users in different scenarios (sitting, lying, or exercising, etc.).

[0083] More specifically, since the shell 102 is customized for the user, the ear-wearable device 10 of the present application has high wearing comfort and is firmly worn and not easily fallen off, because the shell 102 is customized for the user and has better fit with the user's ear (e.g. the external auditory canal, the concha cavity, the cymba concha, the tragus and / or the antitragus) and is not likely to cause compression to the user's ear. In the case of good wearing comfort and firmness, the user can wear the ear-wearable device for a longer time and can wear the ear-wearable device in various scenarios (sitting, lying or exercising, etc.). That is, since the shell 102 is customized according to the shape of the user's ear, both the comfort and stability of the ear-wearable device worn by different users in various scenarios are ensured, and the ear-wearable device has good contact with the user's ear. Since the sub-shell 1024 is part of the shell 102, the shell 102 is customized according to the shape of the ear, and the sub-shell 1024 is also customized according to the shape of the ear. The area of the sub-shell 1024 in contact with the user's ear has an opening, the opening includes the emission window 202 and the receiving window 204, and the barrier 108 is at least partially located in the opening. The sub-shell 1024 is equivalent to the shell 102 of the optical sensor, and the sub-shell 1024 is customized according to the shape of the ear, which is equivalent to the shell 102 of the optical sensor being 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) in contact with the human ear has stable and good contact with the user's ear, which can avoid the light emitted by the light emitting device 104 from leaking to the external environment. At the same time, the barrier 108 is also customized according to the shape of the ear, and the distal end of the barrier 108 has good and stable contact with the ear, which avoids 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.

[0084] In summary, both the shell 102 and the barrier 108 are customized according to the shape of the user's ear. The entire ear-wearable device (mainly referring to the shell 102) and the optical sensor (mainly referring to the outer surface of the sub-shell 1024 and the distal end of the barrier 108) have stable and good contact with the user's ear, and have high wearing comfort. Whether the user is in different states (sitting, lying or exercising, etc.) or different users wear the ear-wearable device, the optical sensor can avoid light leakage to the external environment, and the light emitted by the light emitting device 104 can not be directly received by the light receiving device 106 without being reflected by the human skin, the consistency of the light path is good, and the measurement accuracy of the optical sensor is high.

[0085] In addition, the shell 102 and the barrier 108 are manufactured by the one-piece manufacturing process, the process is simpler and more convenient, the shell 102 and the barrier 108 are seamlessly connected, and have smooth lines, especially the outer surface of the shell 102 and the distal end part of the barrier 108 can also ensure the smooth line design, thereby improving the wearing comfort and stability. It can be understood that the barrier 108 can be a part of the shell 102, and in the embodiment, the shell 102 and the barrier 108 are named separately for functional division. When the barrier 108 is a part of the shell 102, the sub-shell 1024 of the optical sensor and the barrier 108 are both a part of the shell 102, and at this time, the shell 102 is manufactured by the one-piece manufacturing process, and the sub-shell 1024 of the optical sensor and the barrier 108 are also obtained, thereby greatly simplifying the manufacturing process. In particular, when the shell 102 is customized according to the ear shape, the customized sub-shell 1024 and the barrier 108 are obtained, and the outer contour of the optical sensor and the distal end of the barrier are also customized according to the ear shape, thereby simplifying the manufacturing process and ensuring that the ear wearable device and the optical sensor are in stable and good contact with the user's ear, so that the optical path of the optical sensor is consistent, and the optical measurement precision is high.

[0086] In other embodiments, of course, the barrier 108 can not be a part of the shell 102, and the barrier 108 and the shell 102 can be manufactured separately and then combined together by a certain technical means.

[0087] When the user wears the ear wearable device 10, the opening of the sub-shell 1024 can be in contact with the concha cavity, the concha crus, the external auditory canal, the tragus and / or the antitragus, that is, the optical sensor can be in contact with the concha cavity, the concha crus, the external auditory canal, the tragus and / or the antitragus. The above is only an example, and the present application does not specifically limit the area where the opening of the sub-shell 1024 is in contact with the ear.

[0088] In some embodiments, the opening of the sub-shell 1024 is in contact with at least part of the tragus and / or the antitragus.

[0089] As shown in FIG. 3, the tragus is the A position in FIG. 3. As shown in FIG. 4, the antitragus is the B position in FIG. 4.

[0090] The opening of the sub-housing 1024 contacting at least part of the tragus and / or the antitragus refers to the emitting window 202 and the receiving window 204 contacting the position of at least part of the tragus and / or the antitragus of the user when the user normally wears the ear-wearable device 10. In some embodiments, the opening of the sub-housing 1024 contacts at least part of the tragus. In some embodiments, the opening of the sub-housing 1024 contacts at least part of the antitragus. In some embodiments, the opening of the sub-housing 1024 can contact both the tragus and the antitragus, and in this case, there are multiple openings, and the light emitting device 104 and the light receiving device 106 are multiple groups, which can monitor the physiological parameters of the user at multiple points.

[0091] In some embodiments, the tragus and the antitragus are relatively dense parts of the blood vessels of the human ear, and therefore, the light emitting device 104 and the light receiving device 106 can perform light transmission and reception in the area contacting the tragus and / or the antitragus, so as to achieve non-invasive and convenient physiological parameter monitoring, obtain a more accurate pulse waveform and heart rate, and thus improve the monitoring accuracy of the ear-wearable device 10.

[0092] In some embodiments, as shown in FIG. 5, the ear-wearable device 10 further includes a first light-transmitting element 502 and a second light-transmitting element 504.

[0093] In some embodiments, the first light-transmitting element 502 is arranged in the emitting window 202. At least part of the first light-transmitting element 502 is located above the light emitting device 104.

[0094] In some embodiments, the second light-transmitting element 504 is arranged in the receiving window 204. At least part of the second light-transmitting element 504 is located above the light receiving device 106.

[0095] In some embodiments, the distal end of the first light-transmitting element 502 and the distal end of the second light-transmitting element 504 are matched with the shape of the ear of the user. The distal end of the first light-transmitting element 502 refers to the end of the first light-transmitting element 502 contacting or close to the human ear, and the distal end of the second light-transmitting element 504 refers to the end of the second light-transmitting element 504 contacting or close to the human ear.

[0096] In some embodiments, the first light-transmitting element 502 can protect the light emitting device 104 built in the ear-wearable device 10, and the second light-transmitting element 504 can protect the light receiving device 106 built in the ear-wearable device 10, so that the optical sensor forms a closed whole, thereby achieving the effect of dustproof and waterproof, and prolonging the service life of the ear-wearable device 10.

[0097] Further, the light emitted by the light emitting device 104 is projected to the user's skin through the first light transmitting element 502, and the light reflected by the user's skin is projected to the light receiving device 106 through the second light transmitting element 504, which can improve the coupling effect of the light, thereby reducing the distortion degree of the monitoring data and improving the reliability of the monitoring.

[0098] In some embodiments, the outer surface of the sub-housing 1024, the distal end of the barrier 108, the distal end of the first light transmitting element 502, and the distal end of the second light transmitting element 504 all match the shape of the user's ear, which can make the optical sensor in the emission window 202 and the receiving window 204 area more fit the user's ear, thereby reducing the light leakage and ensuring the correct transmission path of the light. At this time, the outer surface of the sub-housing 1024 of the optical sensor, the distal end of the barrier 108, the distal end of the first light transmitting element 502, and the distal end of the second light transmitting element 504 all match the shape of the user's ear, which is beneficial to further improve the measurement accuracy.

[0099] It should be noted that the first light transmitting element 502 does not only refer to a visually light transmitting element, but refers to an element with a light transmittance greater than or equal to 10%, such as an element with a light transmittance of 20%, 35%, 87%, 100%, etc. Any element with a light transmittance between 10% and 100% can be considered as the first light transmitting element 502. Correspondingly, the second light transmitting element 504 has the same setting requirements as the first light transmitting element 502, which will not be described here.

[0100] Preferably, the first light transmitting element 502 and the second light transmitting element 504 are both elements with a light transmittance greater than or equal to 90%.

[0101] Preferably, the first light transmitting element 502 and the second light transmitting element 504 can have a high light transmittance for a certain specific wavelength range of light, without considering the light transmittance of other wavelength ranges. The certain specific wavelength range can be determined according to the wavelength of the light emitted and received by the optical sensor of the ear-wearable device 10.

[0102] In some embodiments, the first light transmitting element 502 and the second light transmitting element 504 are independently formed elements, which are then placed in the emission window 202 and the receiving window 204.

[0103] In some embodiments, the first light transmitting element 502 is formed by pouring a first light transmitting material into the emission window 202, and / or the second light transmitting element 504 is formed by pouring a second light transmitting material into the receiving window 204.

[0104] In some embodiments, the first light-transmissive material and the second light-transmissive material can be the same material or different materials. Preferably, the first light-transmissive material and the second light-transmissive material are the same material, which simplifies the operation of filling the light-transmissive materials into the emission window 202 and the receiving window 204.

[0105] As shown in FIG. 2 and FIG. 5, the ear-wearable device 10 further includes a circuit board 200, the light-emitting device 104 and the light-receiving device 106 are disposed on the circuit board 200, the first light-transmissive element 502 covers the light-emitting device 104 above the circuit board 200, and the second light-transmissive element 504 covers the light-receiving device 106 above the circuit board 200.

[0106] Since the outer surface of the sub-housing 1024 of the optical sensor and the shape of the distal end of the barrier 108 are customized according to the shape of the ear, the shapes of the emission window 202 and the receiving window 204 of different ear-wearable devices 10 are different. It is difficult to adapt to different ear-wearable devices 10 by using standard-sized first light-transmissive elements 502 and second light-transmissive elements 504, and the cost is too high by using customized first light-transmissive elements 502 and second light-transmissive elements 504. By filling the first light-transmissive material into the emission window 202 and the second light-transmissive material into the receiving window 204, the first light-transmissive material and the second light-transmissive material can be solidified in the shape of the emission window 202 and the receiving window 204, respectively, thereby ensuring the matching degree of the first light-transmissive element 502 with the emission window 202 and the matching degree of the second light-transmissive element 504 with the receiving window 204. On the one hand, the process is simple and the cost is low, on the other hand, the first light-transmissive material and the second light-transmissive material can be filled to be substantially flush with the outer surface of the sub-housing 1024 and the distal end of the barrier 108. Since the shape of the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are customized according to the shape of the ear, the distal end of the first light-transmissive element 502 and the distal end of the second light-transmissive element 504 are also matched with the shape of the user's ear. At this time, the outer surface of the sub-housing 1024 of the optical sensor, the distal end of the barrier 108, the distal end of the first light-transmissive element 502, and the distal end of the second light-transmissive element 504 are matched with the shape of the user's ear and have stable and good contact, which can ensure the measurement accuracy in different users and different scenarios (sitting, lying or moving, etc.).

[0107] In some embodiments, the first light-transmissive material and the second light-transmissive material are both light-transmissive resins.

[0108] In some embodiments, the circuit board 200 is fixed on the housing 102 by means of back glue, buckles, etc.

[0109] The back glue and buckle method can firmly fix the optical sensor in the housing 102, reduce the shaking of the optical sensor, and thus improve the user's comfort and measurement accuracy.

[0110] In some embodiments, the first inner side wall 302 of the sub-housing 1024 and the second inner side wall 304 of the barrier 108 enclose the emission window 202, and the first inner side wall 302 and / or the second inner side wall 304 are provided with light-blocking material. And / or, the third inner side wall 306 of the sub-housing 1024 and the fourth inner side wall 308 of the barrier 108 enclose the receiving window 204, and the third inner side wall 306 and / or the fourth inner side wall 308 are provided with light-blocking material.

[0111] Specifically, the green areas shown in FIG. 6 and the green areas shown in FIG. 7 (but it should be understood that the drawings are intended to show the coating position of the light-blocking material, but not to limit the color of the light-blocking material to green) are the setting areas of the light-blocking material.

[0112] In some embodiments, the setting of the light-blocking material can avoid direct leakage of light from the emission window 202 to the receiving window 204, so that the light receiving device 106 directly receives the light leakage without being reflected by the skin, thereby improving the monitoring accuracy of the ear-wearable device 10.

[0113] Further, the light-blocking material can be provided only on the first inner side wall 302 and the second inner side wall 304, or only on the second inner side wall 304, or only on the third inner side wall 306 and the fourth inner side wall 308, or only on the fourth inner side wall 308, or only on the second inner side wall 304 and the fourth inner side wall 308. These embodiments are advantageous to reduce the process complexity and the cost of the light-blocking material. The light-blocking material can also be provided on the first inner side wall 302 and the second inner side wall 304, and on the third inner side wall 306 and the fourth inner side wall 308, which is advantageous to improve the light-blocking effect.

[0114] In some embodiments, the light-blocking material at least includes one of light-shielding ink, a metal layer deposited by metal physical vapor deposition, and a light-blocking patch.

[0115] The light-shielding ink, the metal layer deposited by metal physical vapor deposition, and the light-blocking patch can effectively improve the light-blocking effect, thereby improving the measurement accuracy of the optical sensor.

[0116] In some embodiments, the sub-housing 1024 has an inner surface opposite to an outer surface, and the barrier 108 has a proximal end opposite to a distal end. The outer surface and the distal end are the ends of the optical sensor that contact or are close to the human ear, and the inner surface and the proximal end are the ends that are away from the human ear. The inner surface of the sub-housing 1024 and / or the proximal end of the barrier 108 are coated with light-blocking material.

[0117] The green area shown in FIG. 8 is the coating area of the light-blocking material.

[0118] In some embodiments, the light-blocking material arranged on the inner surface of the sub-housing 1024 and / or the proximal end of the partition 108 can avoid direct leakage of light from the emission window 202 into the receiving window 204, so that the light receiving device 106 directly receives the light leakage without being reflected by the skin, to improve the light-blocking effect, thereby improving the measurement monitoring accuracy of the optical sensor of the ear-wearable device 10.

[0119] In some embodiments, the outer surface of the first light-transmitting element 502 and the outer surface of the second light-transmitting element 504 are both covered with transparent paint.

[0120] In some embodiments, after the first light-transmitting element 502 and the second light-transmitting element 504 are filled, the outer surface of the first light-transmitting element 502 and the outer surface of the second light-transmitting element 504 can be polished first, and then transparent paint is applied to the outer surface of the first light-transmitting element 502 and the outer surface of the second light-transmitting element 504, thereby improving the light transmission efficiency of the light emitting device 104 and the light receiving device 106 and the appearance performance of the ear-wearable device 10.

[0121] In some embodiments, the outer surface of the first light-transmitting element 502 and the outer surface of the second light-transmitting element 504 are both covered with transparent paint.

[0122] In some embodiments, the outer surface of the sub-housing 1024 and / or the distal end of the partition 108 can be coated with transparent paint, thereby increasing the appearance performance of the ear-wearable device 10.

[0123] In some embodiments, the sub-housing 1024 is arranged protruding relative to the main body 1022 or flush.

[0124] As shown in FIG. 9, the sub-housing 1024 is arranged protruding relative to the main body 1022, which can enable the sub-housing 1024 to apply a certain contact pressure to the ear, so that the ear of the wearer is more closely fitted with the sub-housing 1024 in different scenarios (sitting, lying or exercising, etc.), thereby ensuring that the optical sensor fully contacts the ear skin and improving the detection accuracy.

[0125] Further, in order to improve the comfort of the user when wearing the ear-wearable device 10, the protruding distance of the sub-housing 1024 relative to the main body 1022 can be less than or equal to 2.5 mm and greater than any value of 0. For example, it can be 0.5 mm, 1 mm, 2 mm, 2.5 mm. The protruding distance is within 2.5 mm, which not only ensures that the optical sensor fully contacts the ear skin, but also avoids excessive compression of the optical sensor on the ear skin, so that the user feels pain.

[0126] As shown in FIG. 10, the sub-shell 1024 is flush relative to the main body 1022, and 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 can also reduce the presence of the sub-shell 1024, so that the wearer does not feel pain or even leave marks due to the sub-shell 1024 when wearing the ear-wearable device 10 for a long time, thereby increasing the wearing comfort of the user.

[0127] In some embodiments, the shell 102 is a light-transmitting material.

[0128] In some embodiments, the shell 102 can be designed with a light-transmitting material, thereby improving the appearance expressiveness of the ear-wearable device 10 and improving the visual ornamental property.

[0129] Further, after polishing, the shell 102 is coated with transparent paint, thereby further improving the appearance expressiveness of the ear-wearable device 10.

[0130] In some embodiments, the first inner side wall 302 of the sub-shell 1024 and the second inner side wall 304 of the barrier 108 enclose the emission window 202, and the third inner side wall 306 of the sub-shell 1024 and the fourth inner side wall 308 of the barrier 108 enclose the receiving window 204. It should be noted that in order to ensure the detection performance of the ear-wearable device 10, in the case where the shell 102 is a light-transmitting material, light-blocking material needs to be provided on the first inner side wall 302 and the third inner side wall 306, and light-blocking material needs to be provided on at least one of the second inner side wall 304 and the fourth inner side wall 308, so as to avoid the light emitted by the light-emitting device 104 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.

[0131] In some embodiments, as shown in FIG. 11, a method for manufacturing the ear-wearable device 10 is provided, which comprises:

[0132] S1002, customizing the shell 102 according to the shape of the user's ear, the shell 102 comprising a sub-shell 1024 and a barrier 108, the sub-shell 1024 having an opening in the region of the shell 102 that contacts the ear, and the opening comprising an emission window 202 and a receiving window 204, and at least part of the barrier 108 being located in the opening.

[0133] S1004, disposing the light-emitting device 104 in the shell 102 corresponding to the position of the emission window 202, and disposing the light-receiving device 106 in the shell 102 corresponding to the position of the receiving window 204, so as to optically isolate the light-emitting device 104 and the light-receiving device 106 by the barrier 108.

[0134] Wherein, the explanations of terms such as opening can refer to the descriptions in the above embodiments, which will not be repeated here.

[0135] Specifically, the method for manufacturing the ear-wearable device 10 according to the embodiments of the present application can customize the shell 102 according to the shape of the user's ear, so that the shell 102 can perfectly fit the user's ear and achieve the unique customization for each user, thereby improving the wearing comfort, wearing stability and wearing fit of the ear-wearable device 10. The shell 102 is customized according to the shape of the ear of different users, which means that the sub-shell 1024 and the barrier 108 are also customized according to the shape of the ear of different users. No matter the entire ear-wearable device 10 or the optical sensor (mainly referring to the outer surface of the sub-shell 1024 and the distal end of the barrier 108) has a stable and good contact with the ear of each user, and the wearing comfort is high. No matter the user is in different states such as sitting, lying or exercising, or different users wear the ear-wearable device 10, the optical sensor can avoid light leakage to the external environment, and the light emitted by the light emitting device 104 can also avoid being directly received by the light receiving device 106 without being reflected by the human skin. The consistency of the light path is good, and the measurement accuracy of the optical sensor is high.

[0136] In some embodiments, the material of the shell can be photosensitive resin or other polymer materials. The material of the shell can also be metal or dental material, which can be denture base resin. This is just an example, and the present application does not particularly limit the material of the shell.

[0137] Optionally, the shell 102 includes the main body 1022, the sub-shell 1024 and the barrier 108, and the shell 102 can be integrally customized by using 3D printing technology or the like, so as to directly obtain the customized sub-shell 1024 and the barrier 108. This can greatly simplify the manufacturing process of the sub-shell 1024 and the barrier 108, and can also make the shape of the outer surface of the sub-shell 1024 and the distal end of the barrier 108 match the user's ear.

[0138] In some embodiments, the light emitting device 104 is arranged in the shell 102 corresponding to the position of the emission window 202, and the light receiving device 106 is arranged in the shell 102 corresponding to the position of the receiving window 204, so that the light emitted by the light emitting device 104 can be completely reflected by the wearer's skin, and then received by the light receiving device 106 through the receiving window 204, thereby avoiding light interference and improving the light blocking effect. Therefore, the ear-wearable device 10 with high fit and good light blocking effect can be prepared according to the method for manufacturing the ear-wearable device 10.

[0139] In some embodiments, the above method for manufacturing the ear-wearable device 10 further includes:

[0140] The first light-transmissive material is filled in the emitting window 202 by perfusion to form a first light-transmissive element 502, and an outer surface of the first light-transmissive element 502 is flush with an outer surface of the sub-housing 1024 and / or a distal end of the barrier 108.

[0141] The second light-transmissive material is filled in the receiving window 204 by perfusion to form a second light-transmissive element 504, and an outer surface of the second light-transmissive element 504 is flush with an outer surface of the sub-housing 1024 and / or a distal end of the barrier 108.

[0142] In some embodiments, the first light-transmissive material and the second light-transmissive material can be the same material or different materials. Preferably, the first light-transmissive material and the second light-transmissive material are the same material, so that the light-transmissive materials can be filled in the emitting window 202 and the receiving window 204 by perfusion without changing the light-transmissive materials.

[0143] In some embodiments, the first light-transmissive element 502 formed by perfusion can ensure that the first light-transmissive element 502 matches the emitting window 202, and correspondingly, the second light-transmissive element 504 formed by perfusion can ensure that the second light-transmissive element 504 matches the receiving window 204. On the one hand, the perfusion process is simple and low in cost, and on the other hand, the first light-transmissive material and the second light-transmissive material are filled in the sub-housing 1024 and the barrier 108 by perfusion to be substantially flush with the outer surface of the sub-housing 1024 and the distal end of the barrier 108. Since the outer surface of the sub-housing 1024 and the distal end of the barrier 108 are customized according to the shape of the ear, the distal end of the first light-transmissive element 502 and the distal end of the second light-transmissive element 504 also match the shape of the user's ear. At this time, the outer surface of the sub-housing 1024, the distal end of the barrier 108, the distal end of the first light-transmissive element 502, and the distal end of the second light-transmissive element 504 all match the shape of the user's ear and have stable and good contact, which can ensure the measurement accuracy in different users and different scenarios (sitting, lying or moving, etc.).

[0144] In some embodiments, the method for manufacturing the ear-wearable device 10 further includes:

[0145] The light-emitting device 104 and the light-receiving device 106 are disposed on the circuit board 200.

[0146] The first light-transmissive material covers the light-emitting device 104 above the circuit board 200, the second light-transmissive material covers the light-receiving device 106 above the circuit board 200, an outer surface of the first light-transmissive element 502 formed by the first light-transmissive material is flush with an outer surface of the sub-housing 1024 and / or a distal end of the barrier 108, and an outer surface of the second light-transmissive element 504 formed by the second light-transmissive material is flush with an outer surface of the sub-housing 1024 and / or a distal end of the barrier 108.

[0147] The circuit board 200 is fixed on the shell 102.

[0148] Exemplarily, the circuit board 200 can be fixed on the shell 102 by means of back glue, buckles, etc.

[0149] In some embodiments, the method for manufacturing the ear-wearable device 10 further comprises:

[0150] The light-blocking material is arranged on the first inner side wall 302 of the sub-shell 1024 and / or the second inner side wall 304 of the barrier 108; wherein the first inner side wall 302 and the second inner side wall 304 enclose the emission window 202. And / or, the light-blocking material is arranged on the third inner side wall 306 of the sub-shell 1024 and / or the fourth inner side wall 308 of the barrier 108; wherein the third inner side wall 306 and the fourth inner side wall 308 enclose the receiving window 204.

[0151] The arrangement of the light-blocking material can avoid the direct leakage of light from the emission window 202 to the receiving window 204, so that the light receiving device 106 directly receives the light leakage without skin reflection, thereby improving the monitoring accuracy of the ear-wearable device 10.

[0152] In some embodiments, the method for manufacturing the ear-wearable device 10 further comprises:

[0153] The inner surface of the sub-shell 1024 and / or the proximal end of the barrier 108 is coated with light-blocking material; wherein the inner surface of the sub-shell 1024 is a surface arranged opposite to the outer surface of the sub-shell 1024, and the proximal end of the barrier 108 is an end arranged opposite to the distal end of the barrier 108. The outer surface and the distal end are the ends of the optical sensor contacting or close to the human ear, and the inner surface and the proximal end are the ends away from the human ear.

[0154] The light-blocking material arranged on the inner surface of the sub-shell 1024 and / or the proximal end of the barrier 108 can avoid the direct leakage of light from the emission window 202 to the receiving window 204, so that the light receiving device 106 directly receives the light leakage without skin reflection, thereby improving the light-blocking effect and improving the measurement monitoring accuracy of the optical sensor of the ear-wearable device 10.

[0155] In some embodiments, the method for manufacturing the ear-wearable device 10 further comprises:

[0156] The outer surface of the first light-transmitting element 502 and the outer surface of the second light-transmitting element 504 are both covered with transparent paint.

[0157] After the first light-transmitting element 502 and the second light-transmitting element 504 are filled with the liquid, the outer surfaces of the first light-transmitting element 502 and the second light-transmitting element 504 can be polished first, and then transparent paint is applied to the outer surfaces of the first light-transmitting element 502 and the second light-transmitting element 504, so as to improve the light transmission efficiency of the light-emitting device 104 and the light-receiving device 106 and the appearance performance of the ear-wearing device 10.

[0158] In some embodiments, the method for manufacturing the ear-wearing device 10 further includes:

[0159] Transparent paint is applied to the outer surface of the sub-shell 1024 and / or the distal end of the barrier 108, so as to increase the appearance performance of the ear-wearing device 10.

[0160] In some embodiments, the method for manufacturing the ear-wearing device 10 further includes:

[0161] The sub-shell 1024 is protrudingly arranged or flushly arranged relative to the main body 1022.

[0162] The protrudingly arranged sub-shell 1024 can apply a certain contact pressure to the ear, so that the ear of the wearer is more closely fitted with the sub-shell 1024 in different scenarios (sitting, lying or exercising, etc.), thereby ensuring that the optical sensor fully contacts the ear skin and improving the detection accuracy.

[0163] Since the sub-shell 1024 is customized according to the shape of the ear, it can be ensured that the outer surface of the sub-shell 1024 has good contact with the ear of the user, and then the flushly arranged sub-shell 1024 can reduce its presence, so that the wearer does not feel pain or even leave marks when wearing the earphone for a long time, thereby increasing the wearing comfort of the user.

[0164] It should be noted that in the method for manufacturing the ear-wearing device 10, the present application does not have a specific limitation on the order of occurrence of the steps mentioned above, and the order of occurrence of the steps mentioned above can be adjusted, which is within the protection scope of the present application.

[0165] It should be noted that the present application provides an ear-wearing device 10, which can be obtained based on the steps of executing the method for manufacturing the ear-wearing device 10.

[0166] In addition, an ear temperature and blood oxygen detection device is known, which integrates a temperature detection component and a blood oxygen detection component in a small device space. The blood oxygen measurement assembly is composed of a reflective blood oxygen sensor, and the light source of the reflective blood oxygen sensor is converged on the measurement component through a lens. This earphone is only fixed by the protruding part inserted into the external auditory canal, and is very easy to shake or fall off during exercise, thereby affecting the stability and accuracy of detection. Especially in the exercise scene, the movement of the device leads to unstable detection data. In addition, the optical sensor is easily disturbed by ambient light during detection, affecting the accuracy of the detection result.

[0167] In the user activity or exercise scene, the existing ear-wearing device is easy to shake or even fall off, and it is difficult to stably detect the user's physiological data for a long time, and the optical sensor is easily disturbed by ambient light during detection, leading to inaccurate detection results. To solve this technical problem, FIG. 12 shows an ear-wearing device 10 for detecting physiological parameters designed according to the preferred embodiment of the present application. The ear-wearing device 10 has a shell 11, a panel (not visible in FIG. 12), and an optical sensor 15 for detecting user physiological parameters. The optical sensor 15 usually uses a photoplethysmography (PPG) sensor. There are two kinds of measurement principles of PPG: transmission and reflection, and the present application mainly relates to a reflective optical sensor. As shown in FIG. 12, the shell 11 designed according to the preferred embodiment includes a first protruding part 12, a second protruding part 13, and a curved part 14 between them. The panel is mounted to the opening end side of the shell 11 away from the first protruding part 12. The first protruding part 12 is used to be inserted into the user's external auditory canal and fit the external auditory canal, and the second protruding part 13 is used to contact the cymba concha. The curved part 14 between the first protruding part 12 and the second protruding part 13 at least partially contacts the inner surface of the cymba concha and the inner wall of the antitragus. Through such a design of the shell 11, the earphone is stably worn, and even in the exercise scene, the monitoring device of the earphone can still work stably and well.

[0168] As shown in FIG. 12, the curved part 14 between the first protruding part 12 and the second protruding part 13 is an irregular curved surface that at least partially contacts the inner surface of the cymba concha. The optical sensor 15 for detecting user physiological parameters is arranged on the curved part 14, so that the optical sensor 15 can be fitted with the inner surface of the cymba concha. This installation position of the optical sensor 15 is not easily affected by the environment, and since it is on the back of the panel, it is also basically not affected by ambient light.

[0169] Figures 13-17 show the fixing manner of the optical sensor 15 relative to the shell 11. The optical sensor 15 can be fixed on the shell 11, or can be moved relative to the shell 11. The optical sensor 15 shown in Figures 13-17 is fixed in position relative to the shell 11. Figure 13 shows that the outer surface of the optical sensor 15 is flush with the surface of the curved portion 14 of the shell 11; Figure 14 shows that the outer surface of the optical sensor 15 is concave relative to the surface of the curved portion 14 of the shell 11; Figures 15 and 16 show that the outer surface of the optical sensor 15 is convex relative to the surface of the curved portion 14 of the shell 11. The appropriate scheme can be selected according to the actual product requirements. For example, if the curved portion 14 cannot be well fitted to the concha cavity 23, the convex projection type scheme shown in Figures 15 or 16 can be selected, and the convex optical sensor 15 can be as close as possible to the inner surface of the concha cavity 23, so that the measurement result is more accurate; if the curved portion 14 can be well fitted to the inner surface of the concha cavity 23 due to special design, the flush type scheme shown in Figure 13 can be considered, or the concave type scheme shown in Figure 14 can be considered, and the concave type scheme can improve the wearing comfort of the ear-wearable device. If the concave type scheme is selected, the transition between the curved portion and the outer surface of the optical sensor can be smoothed, so as to further improve the wearing comfort. In order to flexibly adjust the positional relationship between the optical sensor 15 and the shell 11, the telescopic type scheme shown in Figure 17 can be considered. The elastic member is arranged below the optical sensor 15, so that the position of the optical sensor 15 can be adjusted according to the distance between the curved portion 14 and the concha cavity 23, so that the optical sensor 15 is always attached to the inner surface of the concha cavity 23.

[0170] As shown in FIG. 13, in the flush type scheme of the optical sensor, the optical sensor 15 includes a light emitting device 154 (may also be referred to as a “light emitting element”), a light receiving device 155 (may also be referred to as a “light receiving element”), a light transmitting element (may also be referred to as a “transparent element”), a partition 108 (may also be referred to as a “partitioning element”), and a substrate 156. The light emitting device 154, the light receiving device 155, the light transmitting element, and the partition 108 are disposed on the substrate 156. The partition 108 is used to separate the light emitting device 154 and the light receiving device 155, so as to avoid the light directly emitted from the light emitting device 154 from being transmitted to the light receiving device 155. The upper surface of the partition 108 can be flush with the lower surface of the light transmitting element, so that the light transmitting element can be used as an integral part to cover the light emitting device 154, the light receiving device 155, and the partition 108, simplifying the overall structure and facilitating installation. In the preferred embodiment shown in FIG. 13, the upper surface of the partition 108 is flush with the outer surface of the light transmitting element, so that the partition 108 divides the light transmitting element into a first light transmitting part 151 and a second light transmitting part 153, the first light transmitting part 151 corresponding to the light emitting device 154, and the second light transmitting part 153 corresponding to the light receiving device 155. The partition 108 completely separates the light transmitting element into two parts, which can further avoid the light directly emitted from the light emitting device 154 from being received by the light receiving device 155 through the light transmitting element, and can also select different light transmitting elements for the light transmitting element and the light receiving device 155 according to their different optical properties, so that the first light transmitting part 151 is more optically matched with the light emitting device 154, and the second light transmitting part 153 is more optically matched with the light receiving device 155. In the flush type scheme of the optical sensor, the upper surface of the partition 108 is also flush with the curved surface 14, ensuring the smoothness of the outer surface of the optical sensor 15, which will not affect the touch feeling of the ear-wearable device and will not press the ear.

[0171] FIG. 14 shows a recessed type scheme of the optical sensor. The structure of the optical sensor 15 is basically the same as that of the flush type scheme of the optical sensor shown in FIG. 13, and the difference is that the outer surface of the optical sensor 15 is recessed relative to the surface of the curved surface 14 of the shell 11, i.e., the outer surface of the light transmitting element is recessed relative to the surface of the curved surface 14 of the shell 11. In this embodiment, the upper surface of the partition 108 is also flush with the outer surface of the light transmitting element, and the partition 108 also divides the light transmitting element into a first light transmitting part 151 and a second light transmitting part 153. The recessed type scheme can improve the wearing comfort of the ear-wearable device, but at the same time, it can also increase the light propagation path. The flush of the upper surface of the partition 108 with the outer surface of the light transmitting element can increase the wearing comfort, and since the light emitting device and the light receiving device are completely separated, the situation that the light emitting angle is increased due to the increase of the light path, so that the light directly emitted from the light emitting device is received by the light receiving device, is avoided, thereby improving the detection accuracy.

[0172] Figure 15 shows a convex scheme of the optical sensor. The structure of the optical sensor 15 is basically the same as the flush scheme of the optical sensor shown in Figure 13, except that the outer surface of the optical sensor 15 is convex relative to the surface of the curved surface portion 14 of the housing 11, i.e. the outer surface of the light-transmitting element is convex relative to the surface of the curved surface portion 14 of the housing 11. In this specific embodiment, the upper surface of the barrier 108 is also flush with the outer surface of the light-transmitting element, and the barrier 108 also divides the light-transmitting element into a first light-transmitting part 151 and a second light-transmitting part 153. The convex optical sensor 15 can be as close as possible to the inner surface of the concha cavity 23, shortening the light propagation path. Since the barrier completely separates the light-emitting device and the light-receiving device, it avoids the situation that the emitted light is directly received by the light-receiving device due to the convex light-emitting device, thereby improving the detection accuracy.

[0173] Figure 16 shows a scheme in which the optical sensor is a multi-channel optical sensor. The multi-channel optical sensor is exemplified by the optical sensor protruding scheme, but the present application is not limited thereto, and the optical sensor with multiple light emitting devices can also be arranged in the flush type, the recessed type, and the telescopic type. In this embodiment, the optical sensor 15 has one light emitting device 154 and two light receiving devices 155, which can be arranged side by side as shown in Figure 18. A barrier 108 is arranged between the light emitting device 154 and the light receiving device 155, and the barrier 108 divides the light-transmitting element into three parts, one first light-transmitting part 151 corresponding to the light emitting device 154, and two second light-transmitting parts 153 corresponding to the light receiving device 155. In the multi-channel light receiving device scheme, the shape of the barrier 108 changes according to the arrangement of the multiple light emitting devices and light receiving devices, as shown in Figures 19 and 20. If the multiple light receiving devices 155 are arranged around the light emitting device 154, the barrier 108 can be arranged in the form of a ring. The upper surface of the barrier 108 is flush with the outer surface of the light-transmitting element, thereby completely separating the multiple light receiving devices 155 and the light emitting device 154. Since the number of light emitting devices is reduced, power consumption is saved; and arranging multiple light receiving devices at different angles can receive more data, thereby improving the accuracy of the measurement results. In another embodiment, the optical sensor 15 has two light emitting devices 154 and one light receiving device 155, which can be arranged side by side. A barrier 108 is arranged between the light emitting device 154 and the light receiving device 155, and the barrier 108 divides the light-transmitting element into three parts, two first light-transmitting parts 151 corresponding to the light emitting device 154, and one second light-transmitting part 153 corresponding to the light receiving device 155. In the multi-channel light emitting device scheme, the shape of the barrier 108 changes according to the arrangement of the multiple light emitting devices and light receiving devices. If the multiple light emitting devices are arranged around the light receiving device, the barrier 108 can be arranged in the form of a ring. The upper surface of the barrier 108 is flush with the outer surface of the light-transmitting element, thereby completely separating the multiple light emitting devices and the light receiving device, especially avoiding the emitted light of the multiple light emitting devices being directly received by the light receiving device, thereby improving the detection accuracy.

[0174] Figure 17 shows a telescopic scheme of the optical sensor. The optical sensor 15 comprises a light emitting device 154, a light receiving device 155, a light transmitting element, a barrier 108 and a substrate 156. The light emitting device 154, the light receiving device 155, the light transmitting element and the barrier 108 are disposed on the substrate 156. An elastic member 157 is disposed below the substrate 156, which supports the optical sensor 15 and can provide elastic force for the optical sensor 15. The elastic member 157 can be a spring, rubber, telescopic sleeve, etc. The elastic member 157 can adjust the position of the optical sensor 15 according to the distance between the curved portion 14 and the inner surface of the concha cavity 23, so that the optical sensor 15 is attached to the inner surface of the concha cavity 23 without too much pressure on the inner surface of the concha cavity 23, improving the wearing comfort. The upper surface of the barrier 108 is flush with the outer surface of the light transmitting element, so that the light emitting device 154 and the light receiving device 155 are completely separated, avoiding the light of the light emitting device 154 being directly received by the light receiving device 155 when the optical sensor 15 moves up and down, thereby improving the detection accuracy.

[0175] In some embodiments, the optical sensor 15 can include one light emitting device 154 and one light receiving device 155. In addition, the optical sensor 15 can include at least two light emitting devices 154 and at least one light receiving device 155, which form a multi-channel optical sensor. The light emitting device can emit red light, infrared light, green light, blue light, or yellow light, which can be used to measure different physiological parameters. Further, the optical sensor 15 can include multiple light emitting devices 154 and one light receiving device 155. The multiple light emitting devices can be used to measure different physiological parameters or the same physiological parameter. The multiple light emitting devices can be arranged at different positions to ensure the accuracy of the measurement results and avoid the situation that the individual position cannot be measured due to the shaking of the earphone. The multiple optical sensors 15 can be used to measure different physiological parameters at the same time, such as blood oxygen, blood pressure, and heart rate. In addition, the optical sensor 15 can include at least one light emitting device 154 and at least two light receiving devices 155. As shown in FIG. 16, the optical sensor 15 includes one light emitting device 154 and two light receiving devices 155. FIG. 18 shows a perspective view of the embodiment of FIG. 16. FIGS. 19 and 20 show two other embodiments, which include three light receiving devices 155 and four light receiving devices 155, respectively. The multiple light receiving devices can be arranged at different positions to reduce power consumption, ensure the accuracy of the measurement results, and avoid the situation that the individual position cannot be measured due to the shaking of the earphone. As shown in FIGS. 18-20, the multiple light receiving devices 155 correspond to one light emitting device 154, which can reduce the number of devices, reduce the cost of the equipment, reduce the overall volume of the optical sensor 15, and facilitate the arrangement. As shown in FIGS. 19 and 20, the light emitting device 154 is surrounded by the annular barrier 108, and the multiple light receiving devices 155 are arranged uniformly in the circumferential direction of the barrier 108. Such an arrangement can place the optical sensor 15 in the smallest space, improve the measurement accuracy, and reduce the power consumption.

[0176] FIG. 21 shows a schematic diagram of the ear tissue. The ear tissue 20 can refer to the concha 21, the helix foot 22, the concha cavity 23, the tragus 24, the antitragus 25, the antihelix 26, and the like. In the design scheme of the present application, the first protruding portion 12 of the shell 11 is used to be inserted into the external auditory canal of the user, the second protruding portion 13 is used to fit the concha 21, the curved portion 14 between the first protruding portion 12 and the second protruding portion 13 at least partially contacts the inner surface of the concha cavity 23 and the inner wall of the tragus 24, and the optical sensor 15 is arranged on the curved portion 14 and can be fitted with the inner surface of the concha cavity 23.

[0177] In addition, the existing technology requires two ear clips to hold the earlobe, resulting in a large overall volume and weight of the earphone, and the ear clips holding the earlobe cause pain and discomfort to the user. To solve the above technical problems, FIG. 22 shows another ear-wearing device 10 for detecting physiological parameters according to the present application. The ear-wearing device 10 includes a housing 11 having a first detection member 191 and a second detection member 192 located on both sides of an ear tissue 20, respectively, as shown in FIG. 23. In the present application, the ear tissue 20 can be a cymba concha 21, a crus of helix 22, a concha cavity 23, a tragus 24, an antitragus 25, an antihelix 26, a helix 27, a scapha 28, etc. In some embodiments, the ear tissue refers to the crus of helix 22.

[0178] In other embodiments, the ear tissue 20 can refer to other parts. The inner wall of the concha cavity 23 can include an inner bottom surface and an inner side surface. The inner bottom surface of the concha cavity 23 refers to the surface of the concha cavity 23 facing the external environment, and the inner side surface of the concha cavity 23 refers to the surface surrounding the inner bottom surface 23. The inner surface of the tragus 24 refers to the surface of the tragus 24 facing the concha cavity 23, and it should be understood that the inner surface of the tragus 24 is part of the inner side surface of the concha cavity 23. The inner surface of the antitragus 25 refers to the surface of the antitragus 25 facing the concha cavity 23, and the inner surface of the antitragus 25 is also part of the inner side surface of the concha cavity 23. The inner wall of the concha cavity 23 can be composed of the inner bottom surface, the inner surface of the tragus 24, the inner surface of the antitragus 25, and the remaining part of the inner side surface. The crus of helix 26 includes an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface. The upper surface refers to the surface facing the cymba concha 21, the lower surface refers to the surface facing the entrance of the external auditory canal and the concha cavity 23, and the side surface refers to the surface facing the external environment.

[0179] In some embodiments, the ear-wearing device 10 further includes a first optical sensor 15 for detecting physiological parameters of a user, the first optical sensor 15 having a light emitting device 154 and a light receiving device 155. The optical sensor generally uses a photoplethysmography (PPG) sensor. The measurement principle of PPG is mainly divided into two types: transmission type and reflection type, and the present embodiment mainly involves a transmission type optical sensor. As shown in FIG. 22, the light emitting device 154 and the light receiving device 155 are respectively arranged on the detection area of the housing 11, i.e., on the first detection member 191 and the second detection member 192. The light emitting device 154 can be disposed on the first detection member 191 or the second detection member 192, and the light receiving device 155 is disposed on the other detection member. In some embodiments, the light emitting device 154 is disposed on the first detection member 191, and the light receiving device 155 is disposed on the second detection member 192.

[0180] In some embodiments, the first optical sensor 15 is a transmissive optical sensor, the light emitted by the light emitting device 154 is received by the light receiving device 155 after transmitting through the ear tissue, thereby measuring the physiological parameter in the ear tissue. The ear-wearable device designed according to the present application can provide more stable and accurate readings compared to the reflective device, because the light transmits through the thicker ear tissue layer and is less affected by external factors. In addition, instead of the ear clip measurement device attached to the ear-wearable device in the prior art, the wearing comfort is improved, long-term wearing does not cause pain, and the overall volume and weight of the ear-wearable device are also reduced, making the device more portable.

[0181] As shown in FIG. 22, in some embodiments, when the ear-wearable device is worn on the ear, the first detection member 191 is located in the cymba concha, and the second detection member 192 is located in the crus of the helix, so that the light emitted by the light emitting device 154 on the detection member 191 is received by the light receiving device 155 after transmitting through the tragus 22. According to another specific embodiment, the first detection member 191 can also be located in the external auditory canal. If there are multiple sets of optical sensors, the first detection member 191 can also be located in the cymba concha and the external auditory canal. The positions of the first detection member 191 and the second detection member 192 can ensure that the light emitting device 154 and the light receiving device 155 transmit through the tragus 22, thereby ensuring the stability of the detection.

[0182] As shown in FIG. 22, in some embodiments, the housing 11 has a first protruding portion 121, a second protruding portion 131, and a curved portion 14 connecting the first protruding portion 121 and the second protruding portion 131. The first protruding portion 121 is at least partially inserted into the external auditory canal of the user and matches the shape of the external auditory canal, the second protruding portion 131 is located in the crus of the helix 21, and the curved portion 14 includes a recessed section avoiding the tragus 22 and a curved section abutting the inner bottom surface of the cymba concha 23.

[0183] It should be understood that there is a shared transition area between the curved part and the first and second protruding parts, and there is no strict boundary. The first protruding part 121 is inserted into the external auditory canal, which can ensure the stable fixation of the device; the second protruding part 131 is attached to the concha, which can provide additional stability; the curved part 14 between the first protruding part 121 and the second protruding part 131 on the opposite side of the panel is an irregular curved surface that at least partially fits the concha cavity 23, further improving the comfort and stability of wearing, and providing a suitable space for arranging sensors, wherein the curved part 14 includes a recessed section that avoids the helix foot 22, and the recessed section has three surfaces corresponding to the upper surface, the lower surface and the side surface of the helix foot, which is the structural basis for realizing the transmission of the helix foot in this embodiment. The curved part 14 avoids the helix foot 22 through the recessed section, i.e. the three surfaces of the recessed section are spaced apart from the helix foot 22, the upper and lower surfaces of the recessed section are attached to the helix foot 22, and the three surfaces of the recessed section are attached to the helix foot 22.

[0184] Further, the three surfaces of the recessed section respectively include a first surface corresponding to the upper surface of the helix foot 22, a second surface corresponding to the side surface of the helix foot 22, and a third surface corresponding to the lower surface of the helix foot 22, wherein the first surface is close to or attached to the upper surface of the helix foot 22, the second surface is close to or attached to the side surface of the helix foot 22, and the third surface is close to or attached to the lower surface of the helix foot 22. In this embodiment, the first detection member 191 is located on the curved part 14, and the second detection member 192 is located on the second protruding part 131.

[0185] In some embodiments, the first detection member 191 can also be located on the first protruding part 121, and the second detection member 192 can also be located on the curved part 14, or the first detection member 191 is located on the first protruding part 121, and the second detection member 192 is located on the second protruding part 131. The structural features of the ear-wearing device can be fully utilized, and additional devices do not need to be added to realize the transmission of the helix foot.

[0186] In some embodiments, the first detection member 191 is located on the curved portion 14 close to or in contact with the lower surface of the crus of the helix, and the second detection member 192 is located on the second protruding portion 131 close to or in contact with the upper surface of the crus of the helix, or the first detection member 191 is located on the first protruding portion 121 close to or in contact with the lower surface of the crus of the helix, and the second detection member 192 is located on the curved portion 14 close to or in contact with the upper surface of the crus of the helix, or the first detection member 191 is located on the first protruding portion 121 (or the curved portion 14) close to or in contact with the lower surface of the crus of the helix, and the second detection member 192 is located on the second protruding portion 131 (or the curved portion 14) close to or in contact with the upper surface of the crus of the helix. On the one hand, the ear wearing device includes the first protruding portion 121, the second protruding portion 131, and the curved portion 14, which increases the wearing comfort and stability, and on the other hand, the positions of the first detection member 191 and the second detection member 192 can ensure that the light emitting device 154 and the light receiving device 155 transmit through the crus of the helix 22, thereby ensuring the stability and accuracy of detection. If multiple sets of optical sensors are provided, the first detection member 191 can be located on the first protruding portion 121 and the curved portion 14, and the second detection member 192 can be located on the second protruding portion 131 and the curved portion 14.

[0187] As shown in FIG. 23, in some embodiments, the light emitted by the light emitting device 154 is received by the light receiving device 155 after transmitting through the crus of the helix 22. The first detection member 191 with the light emitting device 154 is in contact with the lower surface of the crus of the helix 22, and the second detection member 192 with the light receiving device 155 is in contact with the upper surface of the crus of the helix 22, or the first detection member 191 with the light receiving device 155 is in contact with the lower surface of the crus of the helix 22, and the second detection member 192 with the light emitting device 154 is in contact with the upper surface of the crus of the helix 22. Contacting the crus of the helix avoids light loss, which can improve the signal strength and signal-to-noise ratio.

[0188] In some embodiments, the curved portion 14 surrounds the crus of the helix 22 through the recessed section. In this case, the first detection member 191 can be located on the third surface of the recessed section in contact with the lower surface of the crus of the helix 22, and the second detection member 192 can be located on the second protruding portion 131 or the first surface of the recessed section in contact with the upper surface of the crus of the helix 22. Through the positions of the first detection member 191 and the second detection member 192 on the shell and the contact positions with the ear, the first detection member 191 and the second detection member 192 are respectively in contact with the lower surface of the crus of the helix 22 and the upper surface of the crus of the helix 22, thereby achieving the technical effect of the optical sensor transmitting through the crus of the helix 22 scheme with good signal strength and signal-to-noise ratio.

[0189] Here, the positions of the first detection member 191 and the second detection member 192 are not specifically limited, as long as the helotriquetinal crus 22 can be transmitted, and the first detection member 191 and the second detection member 192 abut against the lower surface of the helotriquetinal crus 22 and the upper surface of the helotriquetinal crus 22. If the recessed section also abuts against the helotriquetinal crus 22, a comprehensive wrapping of the helotriquetinal crus 22 is formed, and a completely closed space is formed, which is advantageous for the reliability of detection. Of course, the recessed section can also be spaced apart from the helotriquetinal crus 22, which increases the design flexibility while avoiding excessive pressure on the helotriquetinal crus. According to another specific embodiment, the first detection member 191 can also not abut against the helotriquetinal crus, and only the second detection member 192 abuts against it, or the second detection member 192 does not abut against the helotriquetinal crus, and only the first detection member 191 abuts against it, or neither the first detection member 191 nor the second detection member 192 abuts against the helotriquetinal crus, but maintains a certain distance from the helotriquetinal crus, which increases the position design flexibility and is not limited by the shape and size of the helotriquetinal crus, and improves the adaptability and universality of the device.

[0190] In some embodiments, as shown in FIG. 24, the ear-wearing device 10' is an ear-hanging device. The ear-wearing device 10' has an ear-hanging assembly 16' and a main machine assembly 17', the first detection member 191' is arranged on the ear-hanging assembly 16', the second detection member 192' is arranged on the main machine assembly 17', the light emitting device 154' is arranged on the first detection member 191', and the light receiving device 155' is arranged on the second detection member 192'. Of course, the positions of the light emitting device 154' and the light receiving device 155' can be interchanged. The light emitted by the light emitting device 154' can be transmitted through the helicon 27, the antihelix 26, the concha cavity 23 or the scaphoid 28 and received by the light receiving device 155'.

[0191] In some embodiments, as shown in FIG. 25, the ear-wearing device 10" is an ear-clamping device. The first detection member 191" and the second detection member 192" clamp the ear tissue 20, and the first detection member 191" and the second detection member 192" are connected through the connecting member 18". The light emitting device 154" is arranged on the first detection member 191", and the light receiving device 155" is arranged on the second detection member 192". Of course, the positions of the light emitting device 154" and the light receiving device 155" can be interchanged. The light emitted by the light emitting device 154" can be transmitted through the helicon 27, the antihelix 26, the concha cavity 23 or the scaphoid 28 and received by the light receiving device 155".

[0192] In some embodiments, the ear-wearable device 10, 10', 10" can further comprise a second optical sensor for detecting a physiological parameter of the user, the second optical sensor being disposed on the first detection member and / or the second detection member. The second optical sensor can be a reflective optical sensor or a transmissive optical sensor for measuring a different or same physiological parameter as the first optical sensor 15. If the second optical sensor is also a transmissive optical sensor, the second optical sensor is disposed on both the first detection member and the second detection member, different from the position of the first optical sensor 15; if the second optical sensor is a reflective optical sensor, the second optical sensor only needs to be disposed on the first detection member or the second detection member. It is further preferred that the second optical sensor has a reflective light receiving device which is located on the same side as the light emitting device of the first optical sensor and is capable of receiving the detection light reflected from the ear tissue by the light emitting device. In this way, the second optical sensor can not have a light emitting device, which reduces the cost of components and saves the device space.

[0193] In some embodiments, the ear-wearable device 10, 10', 10" can be used to detect the blood oxygen, blood pressure or heart rate of the user. The detection of different physiological parameters can be achieved by multiple sets of optical sensors. In addition, the ear-wearable device 10, 10', 10" of the present application can be applied to products such as hearing aids or earphones, and through the improved housing design and optical sensor arrangement, stable wearing and high-precision physiological parameter detection can be achieved, which has a wide application prospect.

[0194] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
