[0040] The health of the body has always been a matter of concern and attention to people; heart sounds and lung sounds are two important physiological signals of the human body, which can reflect the health of the heart and lungs to a certain extent. At present, signal acquisition is carried out using instruments such as stethoscopes, and if ordinary users want to detect heart sound signals, they must be equipped with stethoscopes or other detection instruments, and cannot detect them anytime and anywhere.

[0041] In order to solve the above problems, the present invention proposes a wrist-worn device 100, which is convenient for users to measure heart sounds or lung sounds at any time.

[0042] Combined with reference Figures 1 to 3 In one embodiment of the present invention, the wrist-worn device 100 includes a device body 1, a wristband 2 and a signal acquisition module 3. The wristband 2 is connected to the device body 1; the signal acquisition module 3 is arranged on the wristband 2 and can move along the length direction of the wristband 2. Part of the signal acquisition module 3 is exposed on the surface of the wristband 2 to form a driving structure 32. The signal acquisition module 3 is provided with a bone voiceprint sensor 31 for collecting heart sound signals and / or lung sound signals.

[0043] Specifically, the device body 1 in the wrist-worn device 100 can be a watch body (for example, it can be an ordinary watch dial, a smart watch dial, or a bracelet body, etc.), or it can be a health monitoring module (generally refers to a watch body without a screen display function, for example, it can be provided with monitoring sensors for monitoring the user's heart rate, blood pressure, etc., and it can also be provided with sensors for monitoring exercise status, walking steps, etc.).

[0044] In the present invention, the wristband 2 is connected to the device body 1. The wristband 2 can be set as an integrated structure, and its two ends are respectively connected to the device body 1; the wristband 2 can also include two belt bodies respectively connected to the device body 1, and the two belt bodies can be connected to each other. The wristband 2 and the device body 1 can form a ring structure, so that the wrist-worn device 100 can be worn on the user's wrist.

[0045] The signal acquisition module 3 is provided with a bone voiceprint sensor 31. When the wrist-worn device 100 is used to detect heart sounds or lung sounds, the wrist-worn device 100 is placed close to the user's chest heart or lung position, and the vibration signal transmitted from the heart or lung to the skin surface through organs such as bones can be picked up, and the vibration signal is converted into an electrical signal, which is the heart sound signal or lung sound signal. The signal acquisition module 3 can be electrically connected to the main control module 12 of the wrist-worn device 100 through a structure such as a wire or a flexible circuit board 35, so as to transmit the electrical signal converted from the picked-up heart sound signal or lung sound signal to the main control module 12, and the main control module 12 processes the electrical signal.

[0046] In the embodiment of the present application, the signal acquisition module 3 is arranged on the wristband 2, and can be embedded inside the wristband 2, or can be arranged on the surface of the wristband 2. It can be understood that it is easier for users to put the palm side of the wrist close to the palm, the radial side of the wrist close to the thumb, and the ulnar side of the wrist close to the little finger close to the chest. When the wrist-worn device 100 is worn, the device body 1 is usually located on the back of the wrist close to the back of the hand. If the signal acquisition module 3 is arranged on the device body 1, it is not convenient to make the signal acquisition module 3 close to the heart or lung position of the wearer's chest. If the vibration signal of the heart sound or lung sound is transmitted to the chest surface and then transmitted to the signal acquisition module 3 arranged on the device body 1 through the wrist bone, the vibration signal is severely reduced and easily affected by external noise, affecting the accuracy of the acquisition and detection of the heart sound signal and / or lung sound signal. The present application sets the signal acquisition module 3 on the wristband 2, which is convenient for the signal acquisition module 3 to be close to the chest with the wristband 2 when the wrist-worn device 100 is worn, so that the signal acquisition module 3 can more accurately collect the heart sound signal and / or lung sound signal.

[0047] Furthermore, the installation position of the signal acquisition module 3 on the wristband 2 can be adjusted. A plurality of installation slots can be set in the wristband 2 along its length direction. The signal acquisition module 3 can be detachably set in any installation slot. The installation position of the signal acquisition module 3 can be adjusted by setting the signal acquisition module 3 in different installation slots. Alternatively, an installation space 213 extending along its length direction can be set in the wristband 2. The signal acquisition module 3 can be slidably set in the installation space 213. The installation position can be adjusted by sliding the signal acquisition module 3. In some embodiments, the signal acquisition module 3 can also be slidably sleeved on the wristband 2, which is not limited here. Part of the signal acquisition module 3 is exposed on the surface of the wristband 2 as a driving structure 32, so that the user can move the signal acquisition module 3. This setting method makes it easy for the wearer to adjust the signal acquisition module 3 to a position that suits his / her own usage habits, so that the wearer can use the wrist-worn device 100 to detect his / her own heart sound signals and / or lung sound signals more conveniently and comfortably. In addition, for users with different wrist thicknesses, the ring structure formed when the wrist-worn device 100 is worn has different sizes. If the signal acquisition module 3 is fixed at the same position of the wristband 2, when users with different wrist thicknesses wear the wrist-worn device 100, the relative position of the signal acquisition module 3 to the wearer's wrist is also different, so that the installation position of the signal acquisition module 3 is adjustable, and it is also convenient for users with different wrist thicknesses to adjust the position of the signal acquisition module 3 according to their own habits to detect heart sound signals and / or lung sound signals.

[0048] The wristband 2 has two surfaces arranged back to back, and two side surfaces respectively connected to the two surfaces; optionally, the driving structure 32 of the signal acquisition module 3 can be exposed on any surface or any side surface, or can be exposed on at least two of the two surfaces and the two side surfaces, for example, it can be exposed on both side surfaces, or on one of the side surfaces and one of the surfaces; the driving structure 32 can also be exposed on both side surfaces and one of the surfaces, or the signal acquisition module 3 can be mounted on the wristband 2, which is not limited here.

[0049] That is, the technical solution of the present invention is to set a signal acquisition module 3 in the wristband 2 of the wrist-worn device 100, and the signal acquisition module 3 can detect signals such as heart sounds and lung sounds. The wearer of the wrist-worn device 100 only needs to place the wrist-worn device 100 on the heart or lung position of the chest, and the bone voiceprint sensor 31 in the signal acquisition module 3 can collect the vibration signal transmitted from the heart or lung to the chest surface, so as to realize the collection and detection of the heart sound signal or lung sound signal of the wearer, so that the wearer can detect the heart sound signal and / or lung sound signal at any time; and the signal acquisition module 3 is set on the wristband 2, which makes it easier to put the signal acquisition module 3 close to the chest with the wristband 2, thereby improving the accuracy of signal detection.

[0050] In addition, the signal acquisition module 3 can move along the length direction of the wristband 2 to adjust its installation position, so that the wearer can adjust the signal acquisition module 3 to a position that suits his or her own usage habits. For wearers with different wrist thicknesses, the signal acquisition module 3 can also be adjusted to a suitable position so that the wearer can more conveniently and comfortably place the signal acquisition module 3 close to the chest to clearly collect the wearer's heart sound signals and / or lung sound signals, thereby improving the applicability of the wrist-worn device 100 and the accuracy of signal acquisition.

[0051] See also Figure 2 In one embodiment, an installation space 213 extending along the length direction of the wristband 2 is provided in the wristband 2, the installation space 213 has an opening connected to the outside, the signal acquisition module 3 is arranged in the installation space 213, and the driving structure 32 is exposed in the opening.

[0052] In this embodiment, the signal acquisition module 3 is arranged in the installation space 213 of the wristband 2 to prevent the bone voiceprint conductor from being directly exposed to the external environment. The wristband 2 can be used to protect the signal acquisition module 3, reduce the risk of damage to the signal acquisition module 3, and improve performance stability; and make the appearance of the wrist-worn device 100 relatively neat. The wristband 2 has two surfaces arranged back to back, and two side surfaces connected to the two surfaces respectively; optionally, the opening of the installation space 213 can be arranged on any surface or any side of the wristband 2, which is not limited here.

[0053] See also Figure 2In one embodiment, the wristband 2 has a first surface 214 and a second surface 215 which are arranged back to back, and the bone voiceprint sensor 31 contacts the inner wall of the installation space 213 adjacent to the second surface 215; when the wristband 2 and the device body 1 are enclosed to form an annular structure, the first surface 214 is the inner annular surface and the second surface 215 is the outer annular surface.

[0054] In this embodiment, when the wristband 2 and the device body 1 are enclosed to form an annular structure, the first surface 214 of the wristband 2 serves as a part of the inner surface of the annular structure, and the second surface 215 of the wristband 2 forms the outer surface of the annular structure. It can be understood that when the wrist-worn device 100 is worn, the second surface 215 is located on the side away from the user's wrist, exposed to the outside, and the first surface 214 fits the user's wrist. The bone voiceprint sensor 31 in the signal acquisition module 3 is in contact with the inner wall of the installation space 213 adjacent to the second surface 215. In this arrangement, when the user wears the wrist-worn device 100 for heart sound or lung sound detection, the second surface 215 is closer to the user's chest, and the vibration signal transmitted to the second surface 215 can be directly transmitted to the bone voiceprint sensor 31, reducing the attenuation of the vibration signal, so that the bone voiceprint sensor 31 can better pick up the vibration signal, and improve the acquisition accuracy of the heart sound and lung sound signals.

[0055] See also Figure 2 and Figure 4 In one embodiment, the wristband 2 includes a wristband body 21 and a mounting bracket 22. The wristband body 21 is connected to the device body 1 and is provided with a mounting space 213. The mounting bracket 22 is provided in the mounting space 213 and extends along the length direction of the wristband 2. The signal acquisition module 3 is connected to the mounting bracket 22.

[0056] In this embodiment, the wristband 2 includes a wristband body 21 as a main structure and a mounting bracket 22 arranged in the wristband body 21. The wristband body 21 can be made of elastic materials such as silicone, rubber or silicone rubber, so that the wristband 2 can be bent and deformed to adjust the shape and size of the annular structure formed by it and the device body 1, and make the user feel better when wearing the wrist-worn device 100; wherein, the wristband body 21 can be an integrated structure using the same material and hardness, or the wristband body 21 can be formed by a combination of materials of different hardness.

[0057] An installation space 213 for installing the signal acquisition module 3 is provided in the wristband body 21. The installation bracket 22 is arranged in the installation space 213 and can be made of plastic or silicone material with a higher hardness grade. This arrangement method is convenient for fixing the signal acquisition module 3 and can improve the connection strength and position stability of the signal acquisition module 3 and the wristband 2.

[0058] Combined with reference Figure 2 and Figure 6In one embodiment, the mounting bracket 22 is disposed on a side of the bone voiceprint sensor 31 away from the second surface 215 , and the signal acquisition module 3 further includes an elastic structure 33 , which is disposed between the bone voiceprint sensor 31 and the mounting bracket 22 .

[0059] In this embodiment, the mounting bracket 22 is arranged on the side of the bone voiceprint sensor 31 away from the second surface 215, and an elastic structure 33 is arranged between the bone voiceprint sensor 31 and the mounting bracket 22. The elastic structure 33 can be foam, rubber or other elastic pads. This arrangement method uses the elastic structure 33 to apply elastic force to the bone voiceprint sensor 31, so that the bone voiceprint sensor 31 can better contact with the inner wall of the mounting space 213, so as to ensure that the vibration signal transmitted to the second surface 215 can be directly transmitted to the bone voiceprint sensor 31 for collection, thereby improving the collection accuracy of heart sound and lung sound signals.

[0060] See also Figure 2 and Figure 3 In one embodiment, the opening of the installation space 213 is provided on the first surface 214, the installation bracket 22 is provided with a guide groove 221 connecting the installation space 213 and the outside, the driving structure 32 is penetrated through the guide groove 221, and the surface of the installation bracket 22 away from the installation space 213 is provided with a plurality of limiting grooves 222 arranged along its length direction; the driving structure 32 includes a guide portion 321 and a limiting portion 322, the guide portion 321 is penetrated through the guide groove 221, the bone voiceprint sensor 31 and the limiting portion 322 are respectively located at two ends of the guide portion 321, and the limiting portion 322 can be clamped in any limiting groove 222.

[0061] It can be understood that the area of ​​the first surface 214 is relatively large, and the opening of the installation space 213 is set on the first surface 214 of the wristband 2, so that the user can operate the driving unit to adjust the position of the signal acquisition module 3. After the user wears the wrist-worn device 100, the driving structure 32 of the signal acquisition module 3 exposed on the first surface 214 of the wristband 2 is hidden on the side of the wristband 2 facing the user's wrist, which can prevent the signal acquisition module 3 from being exposed to the external environment when the wrist-worn device 100 is worn, thereby avoiding the movement of the signal acquisition module 3 due to the misoperation of the driving structure 32. At this time, the user can adjust the signal acquisition module 3 to a suitable position before wearing the wrist-worn device 100.

[0062] In this embodiment, the mounting bracket 22 is arranged opposite to the opening, and a guide groove 221 and a plurality of limit grooves 222 are arranged on the mounting bracket 22, and the limit groove 222 is arranged on the outer surface of the mounting bracket 22; the guide portion 321 of the driving structure 32 is penetrated through the guide groove 221, so that the limit portion 322 of the driving structure 32 is exposed on the outside of the mounting bracket 22, and the cross-sectional size of the limit portion 322 is larger than the guide groove 221, and is adapted to the shape of the limit groove 222. When there is no need to adjust the position of the signal acquisition module 3, the limit portion 322 is clamped in one of the limit grooves 222 to lock the signal acquisition module 3.

[0063] When the position of the signal acquisition module 3 needs to be adjusted, the limiting part 322 is pulled out from the limiting groove 222 to release the lock on the signal acquisition module 3. At this time, the driving structure 32 can be turned to make the signal acquisition module 3 slide relative to the wristband 2 to adjust the position of the signal acquisition module 3; in the process of pulling the limiting part 322 outward, the driving structure 32 drives the bone voiceprint sensor 31 to move toward the side close to the mounting bracket 22, and squeezes the elastic structure 33, so that the bone voiceprint sensor 31 is spaced from the inner wall of the mounting space 213, thereby avoiding mutual friction between the bone voiceprint sensor 31 and the wristband 2 when the signal acquisition module 3 is moved, improving the smoothness of the sliding process of the signal acquisition module 3, and reducing the risk of damage to the bone voiceprint sensor 31. In addition, in the process of driving the signal acquisition module 3 to slide, the guide groove 221 can guide the signal acquisition module 3, so that the signal acquisition module 3 can accurately slide along the length direction of the wristband 2. After the signal acquisition module 3 is adjusted to the desired position, the limiting portion 322 is released. At this time, under the action of the rebound force of the elastic structure 33, the limiting portion 322 will enter the limiting groove 222 arranged opposite to it, and at the same time, the bone voiceprint sensor 31 will be pushed back by the elastic structure 33 to contact the inner wall of the installation space 213.

[0064] See also Figure 2 and Figure 6 In one embodiment, the signal acquisition module 3 also includes a flexible circuit board 35 and a reinforcement structure 34. Part of the flexible circuit board 35 is arranged on the surface of the reinforcement structure 34 facing away from the mounting bracket 22. The bone voiceprint sensor 31 is arranged on the surface of the flexible circuit board 35 facing away from the reinforcement structure 34 and is electrically connected to the flexible circuit board 35; one end of the driving structure 32 is connected to the reinforcement structure 34, and the elastic structure 33 is clamped between the reinforcement structure 34 and the mounting bracket 22.

[0065] In this embodiment, the reinforcement structure 34 is a roughly plate-like structure having a surface opposite to the mounting bracket 22 and a surface facing away from the mounting bracket 22. The bone voiceprint sensor 31 is disposed on the surface of the reinforcement structure 34 facing away from the mounting bracket 22. The elastic structure 33 is disposed between the reinforcement structure 34 and the mounting bracket 22. The driving structure 32 is penetrated by the elastic structure 33, and one end of the driving structure 32 is connected to the reinforcement structure 34. The arrangement of the reinforcement structure 34 can avoid the driving structure 32 from being directly connected to the bone voiceprint sensor 31, and can avoid the force of the driving structure 32 from being directly applied to the bone voiceprint sensor 31. Optionally, the reinforcement structure 34 and the driving structure 32 are integrally formed.

[0066] The signal acquisition module 3 also includes a flexible circuit board 35 for connecting the bone voiceprint sensor 31 and the main control module 12. Affixing part of the flexible circuit board 35 to the surface of the reinforcement structure 34 can improve the structural strength of the flexible circuit board 35, thereby making the flexible circuit board 35 less susceptible to damage and making the connection between the flexible circuit board 35 and the bone voiceprint sensor 31 more stable.

[0067] Optionally, the main control module 12 is set in the device body 1, and the flexible circuit board 35 can be set longer. The flexible circuit board 35 is bendable and can be bent or stretched when the signal acquisition module 3 is adjusted, thereby avoiding affecting the position adjustment of the signal acquisition module 3.

[0068] Combined with reference Figure 2 and Figure 5 In one embodiment, the wristband 2 includes a main body 211 and a conductive part 212. The main body 211 is configured as a band structure and is connected to the device body 1; the conductive part 212 is embedded in the main body 211 and is enclosed with the main body 211 to form an installation space 213. At least part of the conductive part 212 is located on the side of the installation space 213 facing the second surface 215, and the bone voiceprint sensor 31 is in contact with the conductive part 212; the hardness range of the conductive part 212 is 10 to 20 degrees Shore hardness.

[0069] In this embodiment, the wristband 2 includes a main body 211 and a conducting part 212. The main body 211 is set as a band structure, so that it serves as the main structure of the wristband 2. The main body 211 is made of a material with a certain elasticity, so that the wristband 2 has tension and softness, is easy to deform and can be restored. The conducting part 212 is embedded in the main body 211, and one side surface of the conducting part 212 forms a part of the second surface 215. The main body 211 and the conducting part 212 are connected to form the wristband body 21, and enclosed to form an installation space 213; when there is no need to adjust the position of the signal acquisition module 3, the bone voiceprint sensor 31 is in contact with the conducting part 212, and the vibration signal is transmitted to the bone voiceprint sensor 31 through the conducting part 212. The hardness of the conducting part 212 can be 10 degrees, 12 degrees, 15 degrees, 17 degrees, 19 degrees, 20 degrees, and any value between 10 degrees and 20 degrees, so that the conducting part 212 is relatively soft, which can make it easier for the bone voiceprint sensor 31 to receive the transmitted vibration signal. Optionally, the conducting portion 212 is made of a silicone material having a hardness ranging from 10 degrees to 20 degrees.

[0070] Optionally, the conduction part 212 and the main body 211 can be made of the same material, that is, the conduction part 212 and the main body 211 are integrally formed; the conduction part 212 and the main body 211 can also be made of materials with different hardness, so that the hardness of the main body 211 is higher than that of the conduction part 212, for example, the main body 211 and the conduction part 212 are respectively made of silicone with different hardness. Of course, the materials of the main body 211 and the conduction part 212 can also be different.

The main body 211 and the conductive part 212 are made of materials with different hardness. While the bone voiceprint sensor 31 can better receive the vibration signal through the conductive part 212, it can also meet the structural strength requirements of the wristband 2, and the overall hand feel hardness of the wristband 2 is relatively consistent. Optionally, the hardness of the main body 211 can be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees or any value greater than 20 degrees, which is not limited here. Among them, the main body 211 can be made of silicone, or leather, fabric, rubber or other materials, which are not limited here.

[0073] In one embodiment, the main body 211 is made of a silicone material, which can be a silicone material with the same hardness as the conductive part 212, or a silicone material with a harderness higher than that of the conductive part 212 as in the following embodiment; optionally, the conductive part 212 and the main body 211 are connected as one by injection molding to improve the connection strength and the overall structural stability of the wristband 2.
