Description

Technical Field

[0001] The present invention relates to the technical field of intelligent electronic products, and in particular to a wearable device. Background Art

[0002] Bio-sound detection is an important test item in routine physical examinations. Bio-sound detection includes but is not limited to heart sound detection, lung sound detection, etc. Taking heart sound detection as an example, heart sound detection usually uses a bio-sound sensor to obtain the low-frequency vibration sound waves generated by the heart contraction, so as to analyze the heart health status of humans or animals through the waveform of the sound waves.

[0003] Existing bio-sound sensors are also gradually widely used in smart wearable devices to help users realize daily bio-sound detection more quickly, such as smart wearable watches. Existing bio-sound sensors are directly set in the shell of the wearable device, such as setting a mounting groove and other structures on the shell to place the bio-sound sensor. However, if the bio-sound sensor is placed directly, due to the inevitable installation space between the bio-sound sensor and the shell, the bio-sound sensor and the shell of the wearable device will produce slight relative movement. The rigid support of the shell for the bio-sound sensor is insufficient, resulting in the bio-sound sensor being unable to completely and accurately obtain the bio-sound vibration signal, and the detection accuracy and effect of the bio-sound are poor.

[0039] Please refer to Figures 1 to 3As shown, the present invention proposes a wearable device 100, which includes a shell 1, a substrate 2, a bio-sound sensor 3 and a first elastic member 4. The substrate 2 is arranged on the shell 1, and the substrate 2 and the shell 1 enclose an installation space 2a. The bio-sound sensor 3 is arranged in the installation space 2a and abuts the shell 1. The first elastic member 4 is arranged in the installation space 2a and is connected to the bio-sound sensor 3. The first elastic member 4 applies a force to the bio-sound sensor 3 in the direction of the shell 1 so that the bio-sound sensor 3 is pressed against the shell 1.

[0040] In this embodiment, the wearable device 100 can be a smart watch, a smart bracelet, a smart necklace, a smart ring and other devices. Bio-sound refers to the relevant sounds generated during the heart beating, lung breathing, intestinal digestion, muscle contraction, joint movement and other processes, such as heart sounds generated by heart beating, such as the sound of atrial contraction and ventricular contraction, such as breath sounds, wheezing sounds, dry rales during lung breathing, and bowel sounds during intestinal digestion. The bio-sound sensor 3 is placed on the chest near the heart or lung area, or on the abdomen to obtain vibration signals. The sound is transmitted to the outside world in the form of mechanical waves and can be received by relevant devices or sensors.

[0041] In this embodiment, the bio-sound sensor 3 includes at least one of a bone conduction sensor, a microphone, an acceleration sensor, an inertial sensor, a piezoelectric ceramic, a pressure sensor 6, and a vibration detection sensor.

[0042] It can be understood that the bio-sound sensor 3 can be one or more of the above-mentioned bone conduction sensor, microphone, acceleration sensor, inertial sensor, piezoelectric ceramic, pressure sensor 6, vibration detection sensor, and when multiple of the above-mentioned sensors are set, they can be the same sensor, or different sensors can be used together to adapt to different detection areas and detection environments.

[0043] Among them, if the bio-sound sensor 3 is a bone conduction sensor, it can directly contact the bones and detect the propagation of bio-sound in the body by detecting the vibration of the body bones; if the bio-sound sensor 3 is a microphone, it can detect the bio-sound generated in the body or on the body surface through the vibration sound waves in the air; if the bio-sound sensor 3 is an accelerometer sensor, when the heart beats or the lungs breathe, the body will produce tiny movements and vibrations, and the accelerometer can obtain the changes in the above movements; if the bio-sound sensor 3 is a pressure sensor 6, the pressure sensor 6 can be placed on the surface of the body to capture the pressure changes caused by the heart beating or lung activity. The above types of sensors can convert tiny vibrations into electrical signals and effectively extract the characteristics of bio-sounds to realize the detection of bio-sounds.

[0044] The wearable device 100 in the present application includes at least one bio-sound sensor 3. The at least one bio-sound sensor 3 can be one of the above-mentioned sensors, or multiple types of sensors mentioned above can be used together to acquire signals. There is no limitation on this. The bio-sound sensor 3 receives pressure and sound wave vibrations, and makes the vibrations form analog signals, and then converts the analog signals into digital signals. After signal amplification and signal filtering, the background noise is removed to obtain the final bio-sounds such as heart sound characteristics and breathing characteristics.

[0045] In this embodiment, the shell 1 is the main supporting structure of the wearable device 100, which is a thin shell structure and is enclosed to form an installation cavity. The substrate 2, the bio-sound sensor 3 and the first elastic member 4 can be arranged in the installation cavity, and at the same time, they can also be arranged on the side of the shell 1 facing away from the installation cavity. At the same time, the wearable device 100 also includes a substrate 2, which is used to install the bio-sound sensor 3. The substrate 2 can be a base, a frame, a mounting frame, a mounting plate and other structures. The substrate 2 and the cavity wall of the installation cavity set by the shell 1 are enclosed to form an installation space 2a, so that the bio-sound sensor 3 is limited in the installation space 2a, and the bio-sound sensor 3 is abutted against the surface of the shell 1, that is, the cavity wall of the installation cavity.

[0046] Based on the above embodiments, further, the wearable device 100 also includes a first elastic member 4, which can be an elastic structure such as a spring, a shrapnel, etc., and the first elastic member 4 can be a tension spring or a compression spring. When the first elastic member 4 is a tension spring, the bio-sound sensor 3 is pulled against the shell 1, and when the first elastic member 4 is a compression spring, the bio-sound sensor 3 is pushed against the shell 1. It can also be an elastomeric structure of elastic materials such as rubber, silicone, sponge, polyester elastomer, thermoplastic elastomer (TPE), etc., which is not limited here. One end of the first elastic member 4 is connected or abutted to the side of the substrate 2 facing the shell 1, and the other end of the first elastic member 4 abuts or is connected to the bio-sound sensor 3, and the bio-sound sensor 3 is pressed against the shell 1 by the push of the first elastic member 4.

[0047] It can be understood that the first elastic member 4 is arranged between the substrate 2 and the bio-sound sensor 3, and the first elastic member 4 pushes the bio-sound sensor 3 against the shell 1 through elastic force, thereby eliminating the gap between the bio-sound sensor 3 and the shell 1, so that the bio-sound sensor 3 and the shell 1 form a complete rigid body, so as to eliminate the slight movement of the bio-sound sensor 3 relative to the shell 1 when receiving the bio-sound sound wave vibration, so that the bio-sound sensor 3 can obtain the vibration signal more completely, restore the vibration characteristics to the greatest extent, effectively improve the signal-to-noise ratio of signal acquisition, and improve the accuracy and effect of bio-sound detection. In addition, by setting the first elastic member 4, the bio-sound sensor 3 can always be pushed against the shell 1 to avoid looseness between the bio-sound sensor 3 and the shell 1.

[0048] The wearable device 100 of the technical solution of the present invention includes a shell 1, a substrate 2, a bio-sound sensor 3 and a first elastic member 4. The substrate 2 is arranged on the shell 1, and the substrate 2 and the shell 1 enclose an installation space 2a. The bio-sound sensor 3 is arranged in the installation space 2a and abuts the shell 1. One end of the first elastic member 4 is connected to the substrate 2, and the other end of the first elastic member 4 pushes against the bio-sound sensor 3 to make the bio-sound sensor 3 press against the shell 1. By setting the first elastic member 4 to push against the bio-sound sensor 3 and making the bio-sound sensor 3 always press against the shell 1, the gap between the bio-sound sensor 3 and the shell 1 is eliminated, ensuring that the bio-sound sensor 3 will not produce a slight relative movement with the shell 1 when receiving the bio-sound sound wave vibration transmitted by the shell 1, so that the bio-sound sensor 3 can obtain the vibration signal more completely, restore the vibration characteristics to the greatest extent, effectively improve the signal-to-noise ratio of signal acquisition, and improve the accuracy and effect of bio-sound detection.

[0049] In one embodiment, if Figure 1 and Figure 2 As shown, the shell 1 includes a detection surface 11 and a mounting plane 12; the mounting plane 12 and the substrate 2 are enclosed to form the above-mentioned mounting space, the shell 1 is provided with a detection surface 11 on the side facing away from the mounting plane 12, and the detection surface 11 is configured to contact the user's skin, the substrate 2 is disposed on the mounting plane 12, and the substrate 2 and the mounting plane 12 are enclosed to form an installation space 2a, and the bio-sound sensor 3 abuts against the mounting plane 12 and the first elastic member 4.

[0050] In this embodiment, the wearable device 100 has a detection direction perpendicular to the mounting plane 12. The detection direction is a direction perpendicular to the surface of the shell 1 in contact with the bio-sound sensor 3, and is also a direction consistent with the direction of elastic deformation of the first elastic member 4. The shell 1 includes a detection surface 11 and a mounting plane 12 arranged away from each other along the detection direction, and the detection surface 11 contacts the skin surface of the user; the mounting plane 12 can be a cavity wall of the mounting cavity, or a plane or curved surface structure arranged on the inner wall of the mounting cavity, which is not limited here. The mounting plane 12 provides a stable support platform for the substrate 2 and the bio-sound sensor 3 to ensure that the sensor will not move due to external force during use, thereby maintaining the stability of the signal, wherein the bio-sound sensor 3 abuts against the mounting plane 12 on one side away from the first elastic member 4 along the detection direction, and the bio-sound sound wave vibration or pressure is transmitted to the mounting plane 12 through the detection surface 11, and is transmitted to the bio-sound sensor 3 through the mounting plane 12, so that the bio-sound sensor 3 obtains the bio-sound vibration signal.

[0051] It can be understood that the mounting plane 12 can provide necessary support for the bio-sound sensor 3 to ensure its stability during use. At this time, the signal strength of the vibration signal obtained in the detection direction is stronger, more complete and accurate; bio-sounds, such as heart sounds or lung sounds, will penetrate the skin to transmit vibration sound waves to the outside world. When the detection surface 11 of the shell 1 of the wearable device 100 abuts against the user's skin, the vibration signal will be transmitted to the detection surface 11 of the shell 1, and the bio-sound sensor 3 will obtain the vibration signal from the detection direction of the detection surface 11. At the same time, the detection surface 11 transmits the vibration signal to the mounting plane 12, and transmits it to the bio-sound sensor 3 through the mounting plane 12 to improve the transmission efficiency of the vibration signal and reduce signal attenuation and noise interference.

[0052] In one embodiment, if Figures 1 to 3 As shown, the first elastic member 4 is a compression spring or a tension spring; or, the first elastic member 4 is an elastic block made of an elastic material; or, the first elastic member 4 is an elastic plate made of an elastic material.

[0053] It can be understood that the material of the first elastic member 4 can be one or more of rubber, silicone, sponge, polyester elastomer, thermoplastic elastomer (TPE), or the first elastic member 4 is an elastic structure, such as a compression spring or a spring, so that one end of the first elastic member 4 abuts against the bio-sound sensor 3, and the other end of the first elastic member 4 abuts against the substrate 2, so as to push the bio-sound sensor 3 toward the direction of the shell 1 and press against the surface of the shell 1. The first elastic member 4 can also produce a certain contraction and expansion, so that the shell 1 can completely transmit the vibration to the bio-sound sensor 3.

[0054] In one embodiment, the wearable device 100 also includes a pressure plate, which abuts against the side of the bio-sound sensor 3 facing away from the shell 1; the first elastic member 4 is a tension spring, one end of the first elastic member 4 is connected to the shell 1, and the other end of the first elastic member 4 is connected to the pressure plate.

[0055] It can be understood that the wearable device 100 also includes a pressure plate, which is parallel to the mounting plane 12, that is, the plate surface direction of the pressure plate is perpendicular to the detection direction, and the pressure plate covers the side of the bio-sound sensor 3 facing away from the mounting plane 12. At the same time, the first elastic member 4 is a tension spring, one end of the first elastic member 4 is connected to the mounting plane 12, and the other end of the first elastic member 4 is connected to the shell 1, so that the first elastic member 4 can pull the pressure plate toward the mounting plane 12 along the detection direction, and the pressure plate pushes the bio-sound sensor 3 against the mounting plane 12 of the shell 1 at the same time, so as to ensure that the bio-sound sensor 3 and the mounting plane 12 of the shell 1 are in close contact, and the bio-sound sensor 3 and the shell 1 form a complete rigid body structure, which effectively improves the accuracy and effect of the bio-sound sensor 3 in obtaining vibration signals.

[0056] In one embodiment, if Figure 1 and Figure 3 As shown, the substrate 2 includes a plate body 21 and a limiting protrusion 22, and the limiting protrusion 22 is arranged on the side of the plate body 21 facing the bio-sound sensor 3; one end of the first elastic member 4 abuts the limiting protrusion 22, and the other end of the first elastic member 4 abuts the bio-sound sensor 3.

[0057] In this embodiment, the plate body 21 is the main supporting structure of the substrate 2. The plate body 21 is a flat plate structure. The plate body 21 is detachably connected to the shell 1, such as by bolt connection or snap connection. At the same time, the plate body 21 is opposite to the shell 1 and is arranged at a distance, so that the plate body 21 and the shell 1 enclose an installation space 2a. The limiting protrusion 22 is arranged on the side of the plate body 21 facing the biological sound sensor 3, and preferably, the limiting protrusion 22 is arranged in the center of the plate body 21, so that one end of the first elastic member 4 abuts or is connected to the limiting protrusion 22, and the other end of the first elastic member 4 abuts or is connected to the biological sound sensor 3.

[0058] It can be understood that by providing the limiting protrusion 22, the pressure on the first elastic member 4 of the substrate 2 can be increased, thereby increasing the contact pressure of the first elastic member 4 on the bio-sound sensor 3, so as to compress the first elastic member 4 as much as possible, so that the bio-sound sensor 3 is always pressed against the shell 1, ensuring that the bio-sound sensor 3 and the shell 1 are a complete rigid body structure, thereby ensuring that the vibration received by the shell 1 can be transmitted to the bio-sound sensor 3 without distortion and in a comprehensive manner, avoiding the generation of gaps during the vibration process and affecting the detection accuracy and effect.

[0059] In one embodiment, if Figure 2 and Figure 3 As shown, the limiting protrusion 22 is provided with a limiting groove 221, the groove body of the limiting groove 221 extends along the extension and contraction direction of the first elastic member 4, and the groove opening of the limiting groove 221 is arranged toward the biological sound sensor 3; the first elastic member 4 is limitedly arranged in the limiting groove 221, and part of the biological sound sensor 3 extends into the limiting groove 221 and elastically abuts against the first elastic member 4.

[0060] It can be understood that the limiting protrusion 22 is provided with a limiting groove 221, and the groove body of the limiting groove 221 extends along the detection direction, that is, along the extension and contraction direction of the first elastic member 4, and the notch of the limiting groove 221 is arranged corresponding to the biological sound sensor 3, and at least part of the first elastic member 4 is limited in the limiting groove 221, such as all the first elastic members 4 are arranged in the limiting groove 221 or part of the first elastic members 4 are arranged in the limiting groove 221, and at the same time, one end of the first elastic member 4 away from the limiting groove 221 abuts against the biological sound sensor 3. By setting the limiting groove 221, on the one hand, the first elastic member 4 can be limited to abut against the biological sound sensor 3, and on the other hand, the extension and contraction direction of the first elastic member 4 can be guided, so that when the biological sound sensor 3 obtains the vibration signal and vibrates with the shell 1, the first elastic member 4 can be slightly compressed along the detection direction, ensuring that the biological sound sensor 3 can receive the vibration signal in the detection direction to the greatest extent, restore the vibration characteristics to the greatest extent, effectively improve the signal-to-noise ratio of signal acquisition, and improve the accuracy and effect of biological sound detection.

[0061] In one embodiment, the substrate 2 includes a plate body 21 and a limiting column arranged on the plate body 21, and one end of the limiting column away from the plate body 21 is connected to the shell 1; the limiting column is provided with a mounting hole extending along the detection direction, and the first elastic member 4 and the bio-sound sensor 3 are arranged in the mounting hole; the bio-sound sensor 3 abuts against the hole wall of the mounting hole.

[0062] In this embodiment, one end of the limit column is arranged on the side of the substrate 2 facing the shell 1, and the other end of the limit column extends along the detection direction and passes through the installation space 2a to be connected with the shell 1. The limit column is provided with a mounting hole extending along the detection direction, and the first elastic member 4 and the bio-sound sensor 3 are both arranged in the mounting hole, wherein the bio-sound sensor 3 is arranged in the mounting hole and the side wall of the bio-sound sensor 3 is abutted against the hole wall of the mounting hole.

[0063] It can be understood that by setting a limit column and setting a mounting hole in the limit column, the first elastic member 4 and the bio-sound sensor 3 can be limited more comprehensively to ensure that the position of the bio-sound sensor 3 relative to the shell 1 is accurate, and the change in the position of the bio-sound sensor 3 relative to the shell 1 due to the weakening of the elasticity of the first elastic member 4 after long-term use is avoided. At the same time, the bio-sound sensor 3 abuts against the hole wall of the mounting hole, which can also enhance the rigid connection effect between the bio-sound sensor 3 and the shell 1 and the substrate 2, so that the bio-sound sensor 3 can obtain the vibration signal more completely and accurately.

[0064] In one embodiment, if Figure 1 and Figure 2As shown, the substrate 2 is also provided with a plurality of through holes 23, and the plurality of through holes 23 are arranged around the bio-sound sensor 3, and the shell 1 is provided with a plurality of screw holes 13 corresponding to the through holes 23; the wearable device 100 also includes a plurality of adjustment bolts 5 and a plurality of second elastic members, each adjustment bolt 5 is passed through the through hole 23 and is threadedly connected to the screw hole 13, and the second elastic member is located between the substrate 2 and the shell 1.

[0065] In this embodiment, the hole body of the through hole 23 extends along the detection direction, and multiple through holes 23 are arranged around the bio-sound sensor 3, and multiple through holes 23 are evenly distributed on the surface of the substrate 2, such as being evenly distributed in a ring shape at the periphery of the substrate 2, or being arranged in a rectangular array on the periphery of the substrate 2, which is not limited here. The shell 1 is provided with multiple screw holes 13 corresponding to the through holes 23. The screw holes 13 can be directly opened on the surface of the shell 1, or a mounting seat can be set on the side of the shell 1 facing the substrate 2, and screw holes 13 can be opened on the mounting seat.

[0066] Furthermore, the wearable device 100 also includes multiple adjustment bolts 5 and multiple second elastic parts. The adjustment bolt 5 is usually an elongated cylindrical metal or plastic part with a threaded portion and a non-threaded portion. The second elastic part is a compression spring or a spring sheet. The second elastic part can be sleeved on the outer wall of the adjustment bolt 5. At the same time, the second elastic part is located between the substrate 2 and the shell 1, so that one end of the second elastic part abuts the substrate 2, and the other end of the second elastic part abuts the shell 1. After the adjustment bolt 5 is passed through the through hole 23, its threaded portion is threadedly connected with the screw hole 13.

[0067] It can be understood that by adjusting the connection between the bolt 5 and the thread, the position of the substrate 2 relative to the shell 1 can be fixed, thereby fixing the bio-sound sensor 3 located in the installation space 2a. By adjusting the depth of the threaded connection between the bolt 5 and the screw hole 13, the elastic compression of the second elastic member between the substrate 2 and the shell 1 can be adjusted, thereby adjusting the distance between the substrate 2 and the shell 1 to adjust the elastic contact force of the first elastic member 4 on the bio-sound sensor 3. On the one hand, after long-term use, the change in the elasticity of the first elastic member 4 itself can be offset, and the first elastic member 4 can be ensured to always be pressed against the bio-sound sensor 3. On the other hand, the distance between the substrate 2 and the shell 1 can be adjusted by adjusting the bolt 5 and the second elastic member to adapt to bio-sound sensors 3 of different sizes and thicknesses, thereby improving the flexibility and adaptability of the wearable device 100.

[0068] At the same time, multiple through holes 23 are evenly distributed on the surface of the substrate 2 and arranged around the bio-sound sensor 3, which can also ensure that the substrate 2 always remains perpendicular to the detection direction, that is, to avoid the deflection of the substrate 2 due to inconsistent adjustment positions of various parts of the substrate 2, so as to ensure that the first elastic member 4 always abuts against the substrate 2 and the bio-sound sensor 3 along its extension direction, thereby ensuring that the bio-sound sensor 3 always detects the vibration signal in the detection direction, thereby improving the detection accuracy.

[0069] In one embodiment, if Figure 1 and Figure 2 As shown, the substrate 2 is provided with an avoidance groove 24 ; the bio-sound sensor 3 is provided with a flexible circuit board 32 , and the flexible circuit board 32 is passed through the avoidance groove 24 to be electrically connected with an external circuit.

[0070] It can be understood that the bio-sound sensor 3 includes a sensor body 31 and a flexible circuit board 32. The sensor body 31 is arranged on the detection convex portion, such as being arranged in the accommodating cavity formed by the detection convex portion. The flexible circuit board 32 has good flexibility and conductivity. By setting the circuit used to electrically connect the sensor body 31 and the external circuit as a flexible circuit, the sensor body 31 can be conveniently arranged in the detection convex portion and the accommodating cavity formed by the detection convex portion. For example, the flexible circuit board 32 extends along the cavity wall of the accommodating cavity and is inserted into the avoidance groove 24. Moreover, when the sensor body 31 receives the vibration generated by the detection convex portion, the deformation and vibration generated by the flexible circuit board 32 are much smaller than the deformation and vibration of the traditional printed circuit board, thereby ensuring that the sensor body 31 can receive the vibration to the greatest extent, completely obtain the vibration signal, and effectively improve the detection accuracy.

[0071] At the same time, an avoidance groove 24 is opened on the plate body 21 of the substrate 2. The groove body of the avoidance groove 24 can extend along the detection direction or be extended at an angle to the detection direction. One end of the flexible circuit board 32 is connected to the body of the sensor, and the other end of the flexible circuit board 32 is passed through the avoidance groove 24 and is electrically connected to the external circuit. By setting the avoidance groove 24, it can also be ensured that when the detection convex portion transmits vibration to the sensor body 31 and the flexible circuit board 32, the movement of the flexible circuit board 32 is avoided. On the one hand, the vibration generated by the flexible circuit board 32 can be transmitted to the outside through the avoidance groove 24, and will not be transmitted to the mounting table, substrate 2 and other structures. At the same time, it can also improve the service life of the flexible circuit board 32 and avoid breakage due to frequent bending and vibration at the installation and connection.

[0072] In one embodiment, if Figure 1 and Figure 2 As shown, the wearable device 100 further includes a pressure sensor 6 ; a mounting groove 25 is provided on the side of the substrate 2 facing away from the bio-sound sensor 3 , and the pressure sensor 6 is provided in the mounting groove 25 . The pressure sensor 6 is used to detect the pressure exerted on the bio-sound sensor 3 .

[0073] In this embodiment, a placement groove is provided on the side of the substrate 2 facing away from the bio-sound sensor 3, and the wearable device 100 also includes a pressure sensor 6, which is arranged in the placement groove, wherein the groove body extension direction of the placement groove is the same as the detection direction, and the pressure sensor 6, the first elastic member 4 and the bio-sound sensor 3 are arranged on the same straight line along the detection direction as much as possible.

[0074] It can be understood that by setting up the pressure sensor 6, when the bio-sound sensor 3 receives the vibration signal and squeezes the substrate 2 through the first elastic member 4, the substrate 2 is slightly deformed and the pressure is transmitted to the pressure sensor 6 on the other side. At this time, the pressure obtained by the pressure sensor 6 is the pressure that the shell 1 is subjected to when it abuts against the user's skin.

[0075] It can be understood that the pressure sensor 6 can understand the contact pressure between the wearable device 100 and the user's skin at this time, and remind the user through display or sound that the pressure is within the appropriate range at this time. By adjusting the tightness of the smart watch strap at this time, the pressure between the wearable device 100 and the user's skin is ensured to be appropriate, so that the wearable device 100 reaches the optimal measurement position, so as to ensure that the bio-sound sensor 3 can obtain the vibration signal received by the shell 1 within the appropriate pressure range, so as to improve the efficiency and accuracy of the bio-sound sensor 3 in detecting bio-sounds.

[0076] In one embodiment, if Figure 1 and Figure 2 As shown, along the direction perpendicular to the surface of the substrate 2 , at least a portion of the projection of the pressure sensor 6 onto the substrate 2 overlaps with the projection of the bio-sound sensor 3 onto the substrate 2 .

[0077] It can be understood that, along the direction perpendicular to the surface of the substrate 2, that is, along the detection direction, at least part of the projection of the pressure sensor 6 onto the substrate 2 overlaps with the projection of the bio-sound sensor 3 onto the substrate 2, that is, the center of the pressure sensor 6 and the center of the bio-sound sensor 3 can be completely coincident in the detection direction, or can be offset by a certain distance. When the user uses the wearable device 100, the pressure between the shell 1 and the user's skin will be transmitted to the pressure sensor 6 along the detection direction through the bio-sound sensor 3, the first elastic member 4 and the substrate 2. When at least part of the projection of the pressure sensor 6 onto the substrate 2 overlaps with the projection of the bio-sound sensor 3 onto the substrate 2, the pressure sensor 6 can detect the pressure generated by the first elastic member 4. The pressure transmitted from the elastic member 4 to the substrate 2, preferably, the projection of the pressure sensor 6 onto the substrate 2 completely overlaps with the projection of the bio-sound sensor 3 onto the substrate 2, and at the same time, the projection center of the pressure sensor 6 onto the substrate 2 coincides with the projection center of the bio-sound sensor 3 onto the substrate 2, so that the pressure sensor 6 and the bio-sound sensor 3 are symmetrically arranged on both sides of the substrate 2 along the detection direction, so that the pressure sensor 6 can more completely detect the pressure transmitted to the substrate 2 by the bio-sound sensor 3 through the first elastic member 4, so as to accurately obtain the pressure between the wearable device 100 and the user's skin surface at this time, so that the bio-sound sensor 3 can more accurately obtain the bio-sound vibration signal at this time, thereby improving the detection efficiency and accuracy.

All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
