[0039] Please refer to Figures 1 to 3 As shown, the present invention proposes a wearable device 100, which includes a shell 1, a signal transmission component 2 and a bio-sound sensor 3. The signal transmission component 2 includes a signal transmitter 21 and a signal receiver 22. The signal transmitter 21 and the signal receiver 22 are arranged on two sides of the shell 1 that are away from each other. The bio-sound sensor 3 and the signal transmitter 21 are arranged on the same side of the shell 1. The bio-sound sensor 3 is electrically connected to the signal transmitter 21. The signal transmitter 21 receives the vibration signal collected by the bio-sound sensor 3 and converts the vibration signal into an electromagnetic signal and sends it to the signal receiver 22.

[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 4, 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 4, 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 4, the pressure sensor 4 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, if Figures 1 to 3As shown, the signal transmission component 2 includes a signal transmitter 21 and a signal receiver 22. The signal transmitter 21 and the signal receiver 22 are both miniature transmitters and receivers, which can be radio frequency transmitters and radio frequency receivers, or Bluetooth transmitters and Bluetooth receivers, or infrared transmitters and infrared receivers. At the same time, the signal transmitter 21 and the signal receiver 22 can also perform wireless electromagnetic signal transmission through wireless local area network (Wi-Fi), near field communication (NFC), Zigbee and cellular networks to achieve data transmission.

[0046] At the same time, 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 power supply, control circuit board and other components of the wearable device 100 are arranged in the installation cavity. The signal receiving component 22 of the signal transmission component 2 is arranged on the shell 1 and is located in the installation cavity. The signal transmitting component 21 in the signal transmission component 2 is arranged on the side of the shell 1 facing away from the installation cavity, so that the signal transmitting component 21 and the signal receiving component 22 are arranged on two sides of the shell 1 facing away from each other, and the bio-sound sensor 3 is electrically connected to the signal transmitting component 21, and the bio-sound sensor 3 and the signal transmitting component 21 are both located on the side of the shell 1 facing away from the installation cavity.

[0047] It can be understood that the bio-sound sensor 3 generates a corresponding electrical signal by detecting the low-frequency vibration sound waves of the heart or other biological bodies, and then the bio-sound sensor 3 transmits the acquired electrical signal to the signal transmitter 21 electrically connected to it. After the signal transmitter 21 receives the electrical signal from the bio-sound sensor 3, it converts it into an electromagnetic signal through amplitude modulation and frequency modulation. The signal transmitter 21 then propagates the electromagnetic signal through the air and the shell 1, etc., so that the signal receiving element 22 located on the other side of the shell 1 receives the above-mentioned electromagnetic signal within its working range. The signal receiving element 22 demodulates the received electromagnetic signal, restores the original electrical signal, and converts the electrical signal into a digital signal for subsequent processing and analysis.

[0048] It is understandable that, in a conventional wearable device 100, on the one hand, the bio-sound sensor 3 needs to be electrically connected to the control circuit board disposed in the mounting cavity through a flexible circuit board, and on the other hand, needs to be in contact with the user's skin. Therefore, it is inevitable to open a hole in the shell 1 of the wearable device 100 so that the bio-sound sensor 3 can extend out of the opening of the shell 1 for detection. However, such a setting will cause the wearable device 100 to have a protruding area, which is inconvenient to use as a whole, and increases the direction of waterproofing and failure.

[0049] In the present application, there is no need to make a hole in the shell 1. The vibration signal of the bio-sound sensor 3 can be transmitted through the signal transmitting component 21 and the signal receiving component 22 on both sides of the shell 1, which effectively improves the waterproof and dustproof performance of the wearable device 100, reduces the risk of failure, and improves the overall reliability.

[0050] At the same time, the signal transmitter 21 and the signal receiver 22 are provided in the present application, and there is no need to use a traditional flexible circuit board structure for data and signal transmission, thereby avoiding interference with the collection of the bio-sound signal due to wire vibration when the wearable device 100 obtains the sound wave vibration signal of the user's bio-sound, so that the bio-sound sensor 3 can obtain the bio-sound sound wave vibration signal more completely and accurately.

[0051] The wearable device 100 of the present technical solution includes a shell 1, a signal transmission component 2 and a bio-sound sensor 3. The signal transmission component 2 includes a signal transmitter 21 and a signal receiver 22. The signal transmitter 21 and the signal receiver 22 are arranged on two sides of the shell 1 that are away from each other. The bio-sound sensor 3 and the signal transmitter 21 are arranged on the same side of the shell 1. The bio-sound sensor 3 is electrically connected to the signal transmitter 21; the signal transmitter 21 can receive the vibration signal collected by the bio-sound sensor 3 and convert the vibration signal into an electromagnetic signal and send it to the signal receiver 22. The electromagnetic signal transmission between the signal transmitter 21 and the signal receiver 22 can realize the collection of bio-sound sound wave vibration signals, thereby replacing the physical connection structure of the traditional flexible circuit board, avoiding interference with the collection of bio-sound signals due to wire vibration, and enabling the bio-sound sensor 3 to obtain the vibration signal more completely, restore the vibration characteristics to the greatest extent, effectively improve the signal-to-noise ratio of vibration signal collection, and improve the accuracy and effect of bio-sound detection.

[0052] In one embodiment, if Figures 1 to 3 As shown, the shell 1 includes a surface shell 11 and a support base 12, and the support base 12 is arranged on the surface shell 11; the bio-sound sensor 3 and the signal transmitter 21 are arranged on the support base 12, and at least part of the support base 12 is located between the bio-sound sensor 3 and the surface shell 11.

[0053] In this embodiment, the face shell 11 is the main supporting structure of the shell 1 and the wearable device 100. The face shell 11 has a detection surface that contacts the user's skin. The support seat 12 is arranged on the detection surface of the face shell 11. At the same time, the bio-sound sensor 3 and the signal transmitter 21 are arranged on the support seat 12, and at least part of the support seat 12 is located between the bio-sound sensor 3 and the face shell 11.

[0054] It can be understood that the support base 12 is used to install and support the bio-sound sensor 3 and the signal transmitter 21 on the one hand, ensuring that the bio-sound sensor 3 and the signal transmitter 21 remain in a fixed position during operation to avoid signal interference caused by movement. The support base 12 can absorb and disperse the impact force from the surface shell 11 to a certain extent, reduce the vibration impact on the bio-sound sensor 3, further protect the bio-sound sensor 3 and improve data quality. On the other hand, when the bio-sound sensor 3 and the signal transmitter 21 are arranged inside the support base 12, the bio-sound sensor 3 and the signal transmitter 21 can also be wrapped to improve the waterproof and dustproof performance of the bio-sound sensor 3 and protect the bio-sound sensor 3 and the signal transmitter 21.

[0055] At the same time, at least part of the support base 12 is located between the bio-sound sensor 3 and the surface shell 11, which can effectively isolate the interference of the external environment on the bio-sound sensor 3, reduce the influence of external noise and vibration on the bio-sound sensor 3 obtaining the vibration signal, especially the vibration generated by the surface shell 11 itself, thereby improving the accuracy and stability of the bio-sound sensor 3 obtaining the vibration signal, wherein the support base 12 can be a support block or a support plate, which is not limited here.

[0056] In one embodiment, the support base 12 is made of elastic material and has a deformation cavity; the bio-sound sensor 3 and the signal transmitter 21 are disposed in the deformation cavity, and the cavity wall of the deformation cavity abuts against the bio-sound sensor 3 .

[0057] In this embodiment, the support base 12 is made of elastic material, and the elastic material can be rubber, silicone, sponge, polyester elastomer, thermoplastic elastomer (TPE), etc. Of course, the support base 12 can also be an elastic structure, such as a spring, a spring, etc., wherein the support base 12 set to an elastic material has a connecting end and a detection end, the detection end is set to contact the user's skin surface, and the connecting end is set to connect the surface of the surface shell 11. The sensor structure has a detection direction in which the support base 12 is deformed toward or away from the shell 1, that is, the direction of compression or expansion from the detection end to the connection end to produce deformation. Specifically, the detection end contacts the skin surface of the user's tested area, and the heartbeat or lung breathing will transmit the vibration to the support base 12 of the mounting platform, and the detection end of the support base 12 will also deform in the direction of the connecting end (that is, the direction of the shell 1), and this direction is the detection direction.

[0058] The detection end is set to be made of elastic material. When the support base 12 abuts against the user's skin surface, the detection end is squeezed to produce elastic deformation, so that the support base 12 is always in close contact with the user's skin surface, thereby being able to more completely obtain the vibration signal in the detection direction and restore the vibration characteristics to the greatest extent.

[0059] Based on the above embodiment, further, at least one bio-sound sensor 3 is arranged in the deformation cavity of the support seat 12, such as in a rectangular array or a linear array arranged in the deformation cavity to cover different detection areas, thereby providing a more comprehensive vibration signal. And the part of the support seat 12 made of elastic material or elastic structure can wrap and press against the bio-sound sensor 3 in the detection direction, and the detection direction is also the direction of obtaining the bio-sound vibration signal by contacting the user's skin, so that the support seat 12 can press against the bio-sound sensor 3 in the detection direction while deforming in the detection direction, and transmit the vibration that causes the deformation of the detection end of the support seat 12 to the bio-sound sensor 3, and the bio-sound sensor 3 receives the vibration to realize the detection of bio-sound.

[0060] In the prior art, the bio-sound sensor 3 is directly arranged on the shell 1 of the wearable device 100, so that the vibration signal is easily absorbed by the shell 1 with greater rigidity, resulting in fewer effective vibration signals that can be obtained by the bio-sound sensor 3. At the same time, when receiving the vibration signal, the shell 1 will also generate a large background noise, further affecting the signal-to-noise ratio of the vibration signal obtained by the bio-sound sensor 3, resulting in poor signal quality, poor detection accuracy and effect.

[0061] It can be understood that the present application sets the bio-sound sensor 3 in a support base 12 made of elastic material or elastic structure, so that the bio-sound sensor 3 is isolated by the support base 12 and the elastic abutment with the shell 1, so as to avoid the bio-sound sensor 3 from contacting the shell or other structures of the wearable device 100, and the detection end of the support base 12 contacts the user's skin surface, and can also transmit the vibration to the bio-sound sensor 3 through the elastic deformation of the support base 12 itself, so as to realize the detection of the bio-sound sensor 3, so that it is no longer affected by the shell of the wearable device 100, and 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.

[0062] In this embodiment, the deformation cavity formed by the support seat 12 can be a partially open cavity or a completely closed cavity. At the same time, the deformation cavity can be a cavity with a specific shape, such as a cylindrical cavity, a planar cavity, or a cubic cavity, so as to adapt to bio-sound sensors 3 of different types and shapes, and the bio-sound sensor 3 is arranged at the center of the deformation cavity and pressed against the cavity wall of the deformation cavity in the detection direction, or the bio-sound sensor 3 is bonded to the cavity wall of the deformation cavity of the mounting platform in the detection direction to ensure that the mounting platform is more uniform when transmitting vibration to the bio-sound sensor 3.

[0063] At the same time, when multiple bio-sound sensors 3 are set, the deformation cavity can be a complete cavity, so that multiple bio-sound sensors 3 can be arranged in an array in the deformation cavity at the same time; or the deformation cavity can also be formed by combining multiple independent cavities, so that each bio-sound sensor 3 can be arranged in a small cavity, and multiple independent cavities are distributed in an array, which is not limited here.

[0064] It can be understood that by setting the bio-sound sensor 3 in the deformation cavity of the mounting platform, the bio-sound sensor 3 can be isolated by the deformation cavity so that the bio-sound sensor 3 is in a closed or semi-closed space, thereby effectively reducing the interference of the external structure on the bio-sound sensor 3, and ensuring that the bio-sound sensor 3 obtains the vibration signal more completely, restores the vibration characteristics to the greatest extent, effectively improves the signal-to-noise ratio of the signal acquisition of the bio-sound sensor 3, and improves the accuracy and effect of bio-sound detection.

[0065] Optionally, the support base 12 is bonded to the surface shell 11, or the support base 12 is detachably connected to the surface shell 11.

[0066] In one embodiment, the support base 12 is slidably connected to the face shell 11, and the support base 12 has a deformation cavity; the bio-sound sensor 3 and the signal transmitter 21 are arranged in the deformation cavity, and one end of the bio-sound sensor 3 along the sliding direction of the support base 12 relative to the face shell 11 abuts against the cavity wall of the deformation cavity, and the other end elastically abuts against the face shell 11.

[0067] In this embodiment, the support seat 12 is configured to be able to slide relative to the face shell 11, and the sliding direction of the support seat 12 relative to the face shell 11 is the detection direction. Specifically, a detection hole may be opened on the face shell 11, and the support seat 12 is slidably arranged in the detection hole, and the support seat 12 can approach or move away from the face shell 11 along the detection direction; alternatively, a slide rail may be arranged on the face shell 11, and the support seat 12 is slidably arranged on the slide rail through a slider, which is not limited here.

[0068] Based on the above embodiment, further, the signal transmitter 21 and at least one bio-sound sensor 3 are arranged in the deformation cavity of the support seat 12, such as in a rectangular array or a linear array arranged in the deformation cavity to cover different detection areas, so as to provide a more comprehensive vibration signal. And the support seat 12 can at least wrap and press against the bio-sound sensor 3 in the detection direction, and the detection direction is also the direction of obtaining the bio-sound vibration signal by contacting the user's skin, so that the support seat 12 can press against the bio-sound sensor 3 in the detection direction while deforming in the detection direction, and transmit the vibration that causes the deformation end of the support seat 12 to the bio-sound sensor 3, and the bio-sound sensor 3 receives the vibration to realize the detection of bio-sound.

[0069] At the same time, the bio-sound sensor 3 elastically abuts against the surface shell 11 on the side facing away from the support seat 12 along the detection direction. If an elastic member is arranged between the bio-sound sensor 3 and the surface shell 11, while the support seat 12 slides relative to the surface shell 11 along the detection direction, the bio-sound sensor 3 arranged on the support seat 12 simultaneously compresses the elastic member along the detection direction, so that the surface shell 11 and the support seat 12 jointly press against the bio-sound sensor 3.

[0070] In the prior art, the bio-sound sensor 3 is directly arranged on the shell 1 of the wearable device 100, so that the vibration signal is easily absorbed by the shell 1 with greater rigidity, resulting in fewer effective vibration signals that can be obtained by the bio-sound sensor 3. At the same time, when receiving the vibration signal, the shell 1 will also generate a large background noise, further affecting the signal-to-noise ratio of the vibration signal obtained by the bio-sound sensor 3, resulting in poor signal quality, poor detection accuracy and effect.

[0071] It can be understood that the side of the support seat 12 facing away from the face shell 11 is used to contact the user's skin, and the vibration sound wave signal generated by the user's bio-sound is directly transmitted to the end of the support seat 12 through the skin. The support seat 12 receives the vibration signal and can slide relative to the face shell 11 along the detection direction, while squeezing the bio-sound sensor 3 located between the face shell 11 and the support seat 12, so that the bio-sound sensor 3 obtains the vibration signal.

[0072] It can be understood that the present application sets the bio-sound sensor 3 in the support base 12, and elastically abuts the bio-sound sensor 3 against the face shell 11, so that the bio-sound sensor 3 is isolated by the support base 12, and the bio-sound sensor 3 is also isolated from the external environment, avoiding contact between the bio-sound sensor 3 and the outer shell or other structures of the wearable device 100, so that the vibration signal received by the support base 12 is directly transmitted to the bio-sound sensor 3, so that the bio-sound sensor 3 is no longer affected by the outer shell of the wearable device 100, and 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.

[0073] At the same time, the slidable setting of the support base 12 relative to the face shell 11 can also enable the support base 12 to always keep close to the user's skin surface by sliding when the wearable device 100 is placed in the detection area, so as to obtain the vibration signal more completely, improve the ability to collect bio-sound sound wave vibrations, effectively improve the signal-to-noise ratio of signal collection, and improve the accuracy and effect of bio-sound detection. The bio-sound sensor 3 is elastically abutted against the face shell 11. When the support base 12 slides toward the face shell 11 along the detection direction, the support base 12 can also be limited by elastic abutment to prevent the support base 12 from sliding excessively and causing damage to the bio-sound sensor 3 and the sensor structure.

[0074] In one embodiment, the support seat 12 includes a main body and a limiting portion, the main body forms a deformation cavity, the limiting portion is arranged at the periphery of the cavity opening of the deformation cavity and extends in a direction away from the main body; the surface shell 11 is provided with a through hole, the main body is passed through the through hole, and the limiting portion can be limited to abut the peripheral area of ​​the through hole.

[0075] In this embodiment, the main body forms the above-mentioned deformation cavity, and the main body can be a cylindrical structure. The main body can be slidably arranged in the through hole formed by the face shell 11 of the wearable device 100, or be slidably connected to the face shell 11. The main body is in direct contact with the user's skin, and the main body and the face shell 11 are opposite and spaced apart along the detection direction. The limiting part can be a limiting plate or a limiting boss. The limiting part is arranged at the end of the main body away from the contact with the user's skin, and is arranged at the periphery of the main body. The bio-sound sensor 3 is arranged at the end of the main body away from the contact with the user's skin, and is located in the center of the main body, so that the limiting part is arranged around the bio-sound sensor 3.

[0076] At the same time, the limiting portion extends along the plate direction of the face shell 11 toward the direction away from the main body, and the limiting portion limits and abuts the face shell 11 of the wearable device 100 to limit the entire support seat 12. At the same time, the main body is slidably connected to the face shell 11, so that the entire support seat 12 can also slide relative to the face shell 11. The support seat 12 in this embodiment does not limit the structure and number of the limiting portion. The limiting portion can also be a complete structure, which is arranged on the periphery of the main body and extends in the direction away from the main body, or it can be a plurality of extension arm structures, which extend from the main body to the direction away from the main body.

[0077] It can be understood that the main body is slidably arranged in the through hole formed by the face shell 11 of the wearable device 100, and the main body is used to contact the skin surface of the user to obtain a vibration signal. After obtaining the vibration signal, the main body slides relative to the face shell 11 along the detection direction. At the same time, when the main body is not in contact with the user's skin, the face shell 11 elastically abuts against the bio-sound sensor 3 to push the main body in the direction away from the face shell 11 along the detection direction. At this time, the support seat 12 abuts against the face shell 11 through the limiting portion to ensure the fixation of the position of the support seat 12, that is, the limiting portion can maintain a fixed distance between the face shell 11 and the support seat 12 when not in use.

[0078] In one embodiment, the support seat 12 includes a main body and a sliding part, the main body and the sliding part are elastically connected, the main body forms a deformation cavity, and the sliding part is arranged at the periphery of the cavity opening of the deformation cavity; the surface shell 11 is provided with a sliding groove, the groove body of the sliding groove extends along the surface of the surface shell 11, the sliding part is slidably arranged in the sliding groove, and is limited in the sliding groove.

[0079] It can be understood that the connection between the main body and the sliding part is elastically connected, and the sliding part is arranged at the peripheral position of the cavity opening of the deformation cavity of the main body, and the groove extension direction of the groove extends along the surface of the face shell 11, and extends from the bio-sound sensor 3 as the center to the direction away from the bio-sound sensor 3, so that when the main body is moved toward the face shell 11 due to vibration pressure, the main body can push the sliding part to move along the groove away from the bio-sound sensor 3. In the process of the sliding part sliding along the groove, the main body and the sliding part generate elastic deformation, and the main body approaches or moves away from the face shell 11 to push the bio-sound sensor 3 and squeeze the elastic part between the bio-sound sensor 3 and the face shell 11, thereby transmitting the user's vibration signal to the bio-sound sensor 3.

[0080] In one embodiment, the wearable device 100 further includes a circuit board, and the signal transmitter 21 and the bio-sound sensor 3 are electrically connected to the circuit board and are disposed on two sides of the circuit board facing away from each other.

[0081] It can be understood that the signal transmitter 21 and the bio-sound sensor 3 are arranged on the same circuit board and are electrically connected to the circuit board at the same time, wherein the circuit board can integrate electronic amplifiers, electronic filters and processors, etc., and can transmit the vibration electrical signal obtained by the bio-sound sensor 3 to the signal transmitter 21 through the circuit board. At the same time, the signal transmitter 21 and the bio-sound sensor 3 are located on two sides of the same circuit board facing away from each other, so that the bio-sound sensor 3 and the signal transmitter 21 can be more easily packaged into a circuit package, and the packaged structure of the bio-sound sensor 3 and the signal transmitter 21 is smaller and more compact, thereby reducing the structural size of the support base 12 used to install and place the bio-sound sensor 3 and the signal transmitter 21, reducing the part of the support base 12 protruding from the surface shell 11, and improving the user comfort. In addition, the mutually divergent settings can also reduce the electromagnetic interference of the signal transmitter 21 on the bio-sound sensor 3 to a certain extent, ensuring that the signal collected by the bio-sound sensor 3 is purer.

[0082] In one embodiment, the shell 1 includes a face shell 11 and a plurality of support seats 12, and the plurality of support seats 12 are arranged at intervals on the same side of the face shell 11; the wearable device 100 includes a plurality of bio-sound sensors 3, each bio-sound sensor 3 is arranged on a support seat 12, and the plurality of bio-sound sensors 3 are electrically connected to the signal transmitter 21.

[0083] In this embodiment, the face shell 11 is the main structure of the shell 1, and multiple support seats 12 are arranged at intervals on the same side of the face shell 11, and the side of the face shell 11 on which the multiple support seats 12 are arranged can be a flat surface or a curved surface. The multiple support seats 12 can be adhered to the surface of the face shell 11, or can be detachably arranged on the surface of the face shell 11, such as a snap connection, a bolt connection, etc., which is not limited here. The surface of the face shell 11 on which the multiple support seats 12 are arranged is configured to contact the user's skin, and the multiple support seats 12 are in contact with the user's skin.

[0084] The multiple support seats 12 can all be made of elastic materials, such as one or more of rubber, silicone, sponge, polyester elastomer, thermoplastic elastomer (TPE), or the multiple support seats 12 can also be slidably connected to the face shell 11 and make the bio-sound sensor 3 elastically abut against the face shell 11. At the same time, the wearable device 100 includes multiple bio-sound sensors 3, and each bio-sound sensor 3 is arranged in a deformation cavity formed by a support seat 12.

[0085] It can be understood that by setting multiple support seats 12 on the side of the face shell 11 that contacts the user's skin, and setting a bio-sound sensor 3 in each support seat 12, the user's area to be detected can be covered more comprehensively, such as multiple support seats 12 can relatively completely cover the heart area of ​​the chest, so that the sound wave vibration signals of different areas of the chest heart can be simultaneously obtained through multiple bio-sound sensors 3, including a stronger vibration signal in the center and a weaker vibration signal at the periphery. Further, the obtained sound wave vibration signals of different intensities can be digitized and organized, such as converting the sound wave vibration signal obtained by each bio-sound sensor 3 into a data wave graph, and multiple data wave graphs formed by the sound wave vibration signals of multiple bio-sound sensors 3 are set in the same display area, so as to more clearly and intuitively understand the intensity distribution of the sound wave vibration signals in different detection areas; or the sound wave vibration signals obtained by multiple bio-sound sensors 3 are averaged to obtain a mean waveform graph of the sound wave vibration signals in a complete detection area, so as to quickly understand the user's current health status.

[0086] Based on the above embodiments, further, the signal transmission component 2 can be a signal transmitter 21 and a signal receiver 22, and a signal transmitter 21 is electrically connected to multiple biological sound sensors 3, so that the sound wave vibration signals acquired by the multiple biological sound sensors 3 can be transmitted to the signal transmitter 21, and the signal transmitter 21 is transmitted to the signal receiver 22 in the form of electromagnetic waves; or, the signal transmission component 2 can also be multiple signal transmitters 21 and a signal receiver 22, each signal transmitter 21 is electrically connected to a biological sound sensor 3, and each signal transmitter 21 and a biological sound sensor 3 are arranged in a deformation cavity of a support seat 12, so that the biological sound wave vibration signal can be detected separately through each biological sound sensor 3 and each support seat 12, and the biological sound wave vibration signal can be transmitted to each signal transmitter 21 separately through each biological sound sensor 3.

[0087] It can be understood that multiple bio-sound sensors 3 are electrically connected to the same signal transmitter 21, and the sound wave vibration signal is converted into an electromagnetic signal through the signal transmitter 21 and transmitted to the signal receiving component 22, which effectively simplifies the structure of the wearable device 100 and can improve the integration of the wearable device 100; in another case, the signal transmission component 2 includes multiple signal transmitters 21, and each bio-sound sensor 3 is electrically connected to a signal transmitter 21, so that each signal transmitter 21 can independently obtain the sound wave vibration signal detected by the bio-sound sensor 3, and convert it into an electromagnetic signal and transmit it to the signal receiving component 22. This distributed signal receiving method can ensure that the sound wave vibration signal obtained by each bio-sound sensor 3 can be completely and unattenuated. Converted into an electromagnetic signal and received by the signal receiving component 22, effectively improving the signal-to-noise ratio of vibration signal acquisition and improving the accuracy and effect of bio-sound detection.

[0088] In one embodiment, if Figures 1 to 3 As shown, the wearable device 100 further includes a pressure sensor 4 , which is disposed on the housing 1 ; the pressure sensor 4 is used to detect the pressure exerted on the bio-sound sensor 3 .

[0089] In this embodiment, the pressure sensor 4 is arranged on the shell 1. The pressure sensor 4 can be arranged on the side surface of the shell 1 facing away from the biological sound sensor 3 and spaced apart from the signal receiving element 22; the pressure sensor 4 can also be arranged on the shell 1 and located on the side of the signal receiving element 22 facing away from the shell 1, and the pressure sensor 4 is in contact with the signal receiving element 22, and the side of the signal receiving element 22 facing away from the pressure sensor 4 is in contact with the shell 1.

[0090] It can be understood that by setting up the pressure sensor 4, when the bio-sound sensor 3 receives the vibration signal and squeezes the shell 1 through the first elastic member, the shell 1 is slightly deformed and the pressure is transmitted to the pressure sensor 4 on the other side. At this time, the pressure obtained by the pressure sensor 4 is the pressure that the shell 1 is subjected to when it abuts against the user's skin.

[0091] The pressure sensor 4 can be used to understand the contact pressure between the wearable device 100 and the user's skin at this time, and the user can be reminded through display or sound that the pressure is within an 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 can be 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.

[0092] In one embodiment, along a direction perpendicular to the housing 1 , at least a portion of the projection of the pressure sensor 4 onto the housing 1 overlaps with the projection of the bio-sound sensor 3 onto the housing 1 .

[0093] It can be understood that, along the direction perpendicular to the surface of the shell 1, that is, along the detection direction, at least part of the projection of the pressure sensor 4 onto the shell 1 overlaps with the projection of the bio-sound sensor 3 onto the shell 1, that is, the center of the pressure sensor 4 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 4 through the support seat 12, the bio-sound sensor 3 and the shell 1 along the detection direction. When at least part of the projection of the pressure sensor 4 onto the shell 1 overlaps with the projection of the bio-sound sensor 3 onto the shell 1, the pressure sensor 4 can detect the pressure generated by the support seat. 12 and the pressure transmitted to the shell 1 by the elastic member, preferably, the projection of the pressure sensor 4 onto the shell 1 completely overlaps with the projection of the bio-sound sensor 3 onto the shell 1, and at the same time, the projection center of the pressure sensor 4 onto the shell 1 coincides with the projection center of the bio-sound sensor 3 onto the shell 1, so that the pressure sensor 4 and the bio-sound sensor 3 are symmetrically arranged on both sides of the shell 1 along the detection direction, so that the pressure sensor 4 can more completely detect the pressure transmitted to the shell 1 by the bio-sound sensor 3 through the first elastic member, 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.
