[0040] In response to the technical problems mentioned in the background technology, the present invention proposes a wristband electronic device that is designed to collect heart sounds and lung sounds to understand the health status of the human heart and lungs.

[0041] The specific structure of the wristband electronic device proposed by the present invention will be described in detail below in a specific embodiment:

[0042] like Figures 1 to 4As shown, in one embodiment of the wristband electronic device 100 of the present invention, the wristband electronic device 100 is used to be worn on the wrist, and a microphone 11 is provided inside the wristband electronic device 100. A sound collecting structure 311 is provided on the surface of the wristband electronic device 100 facing away from the wrist, and the sound collecting structure 311 is connected to the microphone 11 through a channel 100a. The sound collecting structure 311 is used to be attached to the chest cavity to collect heart sounds and / or lung sounds and transmit them to the microphone 11.

[0043] In this embodiment, the wristband electronic device 100 may be a smart watch, a smart bracelet, or other wristband electronic devices 100 .

[0044] The wristband electronic device 100 includes a device body 10 and a wristband 30, which is connected to the device body 10. The wristband 30 is used to secure the device body 10 to the wrist. The microphone 11 can be located in the device body 10 or in the wristband 30. Similarly, the sound collection structure 311 can be located in the device body 10 or in the wristband 30. Setting method 1: The microphone 11 is located in the device body 10, and the sound collection structure 311 is located in the wristband 30. The sound collection structure 311 is connected to the microphone 11 through a channel 100a, which can be formed by a flexible tube. Setting method 2: The microphone 11 and the sound collection structure 311 are both located in the wristband 30. The microphone 11 can be connected to the sound collection structure 311 through the channel 100a formed inside the wristband 30. The microphone 11 can be electrically connected to the device body via a flexible circuit board. This can reduce the sound transmission distance, reduce sound wave loss, and improve sound collection quality. Other setting methods are also possible, and those skilled in the art can make settings according to actual needs.

[0045] The sound collection structure 311 can be used to collect heart sounds and lung sounds, or can be used to collect only heart sounds, or can be used to collect only lung sounds. Those skilled in the art can use it according to actual needs.

[0046] The sound collecting structure 311 can be a sound collecting groove 31b. When the groove of the sound collecting groove 31b is attached to the chest cavity, the sound waves of the heart sounds and / or lung sounds in the body are transmitted to the microphone 11 through the air in the sound collecting groove 31b and the air in the channel 100a. It can also be a membrane cavity with a larger area. When the cavity is attached to the chest cavity, the sound waves of the heart sounds and / or lung sounds in the body stimulate the membrane cavity, and the enclosed gas in the channel 100a vibrates and transmits sound waves for the microphone 11 to collect the heart sounds and / or lung sounds. This method is through solid-air sound transmission. The sound collecting structure 311 can also be other structures that effectively collect sound.

[0047] It can be understood that a microphone 11 is provided inside the wristband electronic device 100, and a sound collecting structure 311 is provided on the surface of the wristband electronic device 100 facing away from the wrist. The sound collecting structure 311 is connected to the microphone 11 through the channel 100a. When collecting heart sounds and / or lung sounds, the sound collecting structure 311 is attached to the chest cavity, and the sound waves of the heart sounds and / or lung sounds in the chest cavity are collected by the sound collecting structure 311 and supplied to the microphone 11 through the air in the channel 100a, thereby collecting heart sounds and lung sounds to understand the health status of the human heart and lungs.

[0048] like Figure 1 、 Figure 4 as well as Figure 5 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the wristband electronic device 100 includes:

[0049] a device body 10 , wherein the microphone 11 is provided inside the device body 10 ; and

[0050] The wristband 30 is connected to the device body 10 and is used to be worn on the wrist. The surface of the wristband 30 facing away from the wrist is provided with the sound collecting structure 311.

[0051] In this embodiment, the microphone 11 on the device body 10 and the sound collecting structure 311 on the wristband 30 can be connected to each other through a sound-conducting structure, such as a hose, etc.; the device body 10 and the wristband 30 can also be an integrally formed structure, and a channel 100a is formed inside the structure to connect the microphone 11 with the sound collecting structure 311; or other forms can be used to connect the microphone 11 on the device body 10 and the sound collecting structure 311 on the wristband 30.

[0052] It is understandable that by providing the sound collection structure 311 on the wristband 30, it is convenient to place the sound collection structure 311 on the chest cavity when the wristband electronic device 100 is worn on the wrist to collect heart sounds and / or lung sounds, which can improve convenience. In addition, the microphone 11 generally requires power from the device body 10, while the wristband 30 generally does not require power. If the microphone 11 is provided on the device body 10 and the sound collection structure 311 is provided on the wristband 30, then there is no need for an electrical connection between the wristband 30 and the device body 10, providing a structural basis for the detachable connection between the wristband 30 and the sound collection structure 311.

[0053] In actual applications, when it is necessary to collect heart and lung sounds, the user raises his wrist and places the sound collecting structure 311 on the wristband 30 against the heart or lung position in the chest cavity. The collected audio signals are gathered through the special concave sound collecting structure 311 and then transmitted to the microphone 11 through the closed channel 100a. After the collection is completed, the motor or speaker on the device body 10 will remind the user that the collection is over.

[0054] like Figures 3 to 5 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the channel 100a includes:

[0055] A sound collecting segment 101a, which is provided in the wristband 30, and one end of which is connected to the sound collecting structure 311;

[0056] a sound guiding segment 103a, one end of which is connected to an end of the sound collecting segment 101a away from the sound collecting structure 311; and

[0057] The sound transmission section 105a is provided in the device body 10, one end of the sound transmission section 105a is connected to the microphone 11, and the end of the sound transmission section 105a away from the microphone 11 is connected to the end of the sound guide section 103a away from the sound collection section 101a.

[0058] In this embodiment, the sound guide section 103a can use a hose to connect the device body 10 and the wristband 30 to connect the microphone 11 with the sound collecting structure 311; the sound guide component 33 can also be connected to the wristband 30 by rotatably connecting the sound guide component 33 to the wristband 30, and the sound guide component 33 can be connected to the device body 10 by fixedly connecting the sound guide component 33 to the device body 10, thereby connecting the microphone 11 with the sound collecting structure 311; other effective methods can also be used.

[0059] It can be understood that the device body 10 and the wristband 30 are connected through the sound guide segment 103a, so that the device body 10 and the wristband 30 do not have to maintain a state of being unable to move relative to each other in order to maintain the continuity of the channel 100a connecting the microphone 11 and the sound collecting structure 311. That is, since the sound guide segment 103a can maintain the connection between the device body 10 and the wristband 30, it can allow the device body 10 and the wristband 30 to move relative to each other, and can serve as the basis for achieving a rotational connection between the device body 10 and the wristband 30.

[0060] like Figure 4 and Figure 5 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the wristband 30 includes:

[0061] a belt body 31, one end of which is rotatably connected to the device body 10 and is provided with a receiving groove 31a, the belt body 31 is provided with the sound collecting structure 311, and the belt body 31 is used to be worn on the wrist; and

[0062] The sound guide component 33, the outer surface of the device body 10 facing the accommodating groove 31a is formed with a first connecting port 10a connected to the sound transmission section 105a, the groove wall of the accommodating groove 31a is formed with a second connecting port 310a connected to the sound collecting section 101a, the sound guide component 33 is at least partially accommodated in the accommodating groove 31a, one end of the sound guide component 33 is connected to the sound transmission section 105a through the first connecting port 10a, and the other end is connected to the sound collecting section 101a through the second connecting port 310a.

[0063] In this embodiment, two lugs are protruding from one end of the belt body 31 facing the device body 10, and the two lugs are spaced apart in the width direction of the belt body 31, thereby forming a receiving groove 31a. There are two ways to set the sound guide component 33. Method 1: a part of the sound guide component 33 is located between the two lugs, and the other part of the sound guide component 33 is exposed in the receiving groove 31a and connected to the first connecting port 10a of the device body 10; Method 2: the entire sound guide component 33 is located between the two lugs, and the device body 10 is provided with a connecting piece protruding from the outer surface of the belt body 31, and the connecting piece has a first connecting port 10a. The connecting piece is connected to the sound guide component 33 to achieve communication. The sound guide component 33 is sandwiched between the two lugs, which can prevent the sound guide component 33 from moving in the width direction of the belt body 31.

[0064] It can be understood that a accommodating groove 31a is provided at one end of the belt body 31 connected to the device body 10, and the sound guide component 33 is accommodated in the accommodating groove 31a, so that the sound guide component 33 can move in the accommodating groove 31a, and the belt body 31 is connected to the device body 10 through the sound guide component 33, so that when the belt body 31 and the sound guide component 33 move relative to each other, the channel 100a is maintained in a connected state to ensure that the microphone 11 is connected to the sound collecting structure 311.

[0065] like Figures 2 to 6 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the sound guide component 33 includes:

[0066] a sound guide adapter 331 having two ends facing each other, one end of the sound guide adapter 331 being inserted into the accommodating groove 31a, and the other end of the sound guide adapter 331 extending toward and being inserted into the first communicating port 10a, wherein a first sound channel 331a communicating with the sound transmission section 105a is formed inside the sound guide adapter 331; and

[0067] The sound guide tube 333 is accommodated in the accommodating groove 31a and extends along the rotation axis of the belt body 31 and the device body 10. One end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331, and the other end of the sound guide tube 333 extends toward the second connecting port 310a and is inserted into the second connecting port 310a. A second sound channel 333a is formed in the sound guide tube 333, and the second sound channel 333a is connected to the first sound channel 331a to form the sound guide section 103a.

[0068] It can be understood that one end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331, and the axis of the sound guide tube 333 and the rotation axis of the belt body 31 and the device body 10 are coaxially arranged. Therefore, during the process of rotational connection between the belt body 31 and the device body 10, the connection state of the channel 100a can be maintained by the rotation between the sound guide tube 333 and the sound guide adapter 331 to ensure that the microphone 11 is connected to the sound collecting structure 311.

[0069] Specifically, the rotation axis of the belt body 31 and the device body 10 is defined as the rotation axis. The second communication port 310a extends along the groove wall of the accommodating groove 31a to form a receiving hole, and the receiving hole is coaxially arranged with the rotation axis. One end of the sound guide tube 333 is inserted into the receiving hole, so that the sound guide tube 333 is coaxially arranged with the rotation axis. The other end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331. With such an arrangement, when the user wears the wristband electronic device 100, the belt body 31 rotates around the rotation axis, while the device body 10 and the sound guide adapter 331 remain stationary, and the sound guide tube 333 and the sound guide adapter 331 can rotate relative to each other, so that during the process of rotational connection between the belt body 31 and the device body 10, the belt body 31 can be kept connected to the device body 10 via the sound guide tube 333 and the sound guide adapter 331, thereby keeping the microphone 11 connected to the sound collecting structure 311.

[0070] Furthermore, to minimize sound leakage, two spaced-apart first sealing rings are fitted onto the end of the sound guide adapter 331 facing away from the accommodating groove 31a. One first sealing ring is located within the sound guide sleeve 13 and is squeezed by the inner wall of the sleeve 13. The other first sealing ring is located within the first communication opening 10a and is squeezed by the inner wall of the first communication opening 10a. This seals the connection between the sound guide assembly 33 and the device body 10, minimizing sound leakage.

[0071] The sound guide tube 333 is inserted into one end of the sound guide adapter 331 and is sleeved with a second sealing ring. The outer side of the second sealing ring is squeezed by the inner wall of the first sound channel 331a, thereby sealing the connection between the sound guide tube 333 and the sound guide adapter 331, thereby reducing sound leakage.

[0072] One end of the sound guide tube 333 facing away from the sound guide adapter 331 is inserted into the receiving hole, and the one end of the sound guide tube 333 facing away from the sound guide adapter 331 is sealed. The wall of the sound guide tube 333 is provided with a sound hole connected to the second sound channel 333a. The sound hole and the sound guide hole 310c are in the same area and are connected to each other. Two third sealing rings are provided on the outer side surface of the sound guide tube 333. The sound hole and the sound guide hole 310c are both located between the two third sealing rings. The wall of the receiving hole squeezes the two third sealing rings respectively, so that the connection between the sound guide tube 333 and the receiving hole can be sealed, thereby reducing sound leakage.

[0073] It should be noted that although a second sealing ring is provided at the connection between the sound guide adapter 331 and the sound guide tube 333, when an external force drives the sound guide adapter 331 and the sound guide tube 333 to rotate relative to each other, the friction between the second sealing ring and the sound guide adapter 331 can be overcome, or the friction between the second sealing ring and the sound guide tube 333 can be overcome, thereby achieving relative rotation between the sound guide adapter 331 and the sound guide tube 333. It is understandable that the friction between the second sealing ring and the sound guide adapter 331 is small, or the friction between the second sealing ring and the sound guide tube 333 is small, so that the friction can be overcome, and the sound guide adapter 331 and the sound guide tube 333 can rotate relative to each other.

[0074] like Figures 4 to 6 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the sound guide adapter 331 is inserted into one end of the first communication port 10a and protrudes into the inner cavity of the device body 10;

[0075] The inner cavity of the device body 10 is provided with a sound guide sleeve 13, one end of the sound guide sleeve 13 is sleeved on one end of the sound guide adapter 331 protruding into the inner cavity of the device body 10, and the end surface of the other end of the sound guide sleeve 13 is covered on the microphone 11.

[0076] In this embodiment, one end of the sound guide adapter 331 enters the inner cavity of the device body 10 from the first connecting port 10a. The sound guide sleeve 13 is located in the inner cavity of the device body 10, and the two ends of the sound guide sleeve 13 are interconnected. Among them, one end of the sound guide sleeve 13 is sleeved on one end of the sound guide adapter 331 extending into the inner cavity of the device body 10, and the other end is embedded in the microphone 11. In this way, the microphone 11 can be connected to the sound guide adapter 331, and connected to the sound collecting structure 311 via the sound guide adapter 331. With such a setting, on the one hand, the sound guide sleeve 13 can prevent sound leakage, and on the other hand, the sound guide sleeve 13 can facilitate the connection of the sound guide adapter 331 to the setting body, and also facilitate the installation of the microphone 11 in the inner cavity of the device body 10, thereby improving assembly efficiency.

[0077] It should be noted that the sound guide sleeve 13 can be a silicone sleeve, a sleeve made of plastic material, or other forms of the sound guide sleeve 13.

[0078] like Figure 1 、 Figure 3 as well as Figure 4 As shown, in one embodiment of the wristband electronic device 100 of the present invention, a sound collecting groove 31b is provided on the surface of the wristband electronic device 100 facing away from the wrist, and one end of the sound collecting segment 101a facing away from the sound guiding segment 103a passes through to the bottom wall of the sound collecting groove 31b, and the sound collecting groove 31b forms the sound collecting structure 311, and the sound collecting groove 31b is used to collect heart sounds and / or lung sounds.

[0079] It can be understood that by providing the sound collecting groove 31b, the sound can be gathered and transmitted to the sound collecting segment 101a, so that more heart sounds and / or lung sounds can be collected.

[0080] Specifically, in order to enhance the sound gathering function, the cross section of the sound collecting groove 31b perpendicular to the thickness direction of the belt body 31 is gradually narrowed from the groove mouth to the groove bottom, forming a trumpet-like structure, which can promote the convergence of sound and improve the sound quality of the collected heart sounds and / or lung sounds.

[0081] It should be noted that the sound collecting groove 31b can be an arc-shaped groove, a trapezoidal groove, or a groove of other shapes.

[0082] like Figure 3 and Figure 4 As shown, in an embodiment of the wristband electronic device 100 of the present invention, a protrusion 310b is provided on the bottom of the sound collecting groove 31b.

[0083] It can be understood that the raised portion 310b is provided on the bottom of the sound collecting groove 31b, which can prevent the sound guide section 103a from being blocked by clothing or skin when collecting sound and passing through one end of the bottom wall of the sound collecting groove 31b. That is, it can prevent the sound hole 311b from being blocked by clothing or skin, affecting the quality of the collected signal.

[0084] It should be noted that the number of the protrusions 310b can be 1, 2, 3, 4, 5, 6, etc. There is no limitation on the number of the protrusions 310b, and those skilled in the art can set them according to actual needs.

[0085] like Figures 2 to 4As shown, in an embodiment of the wristband electronic device 100 of the present invention, the wristband electronic device 100 is provided with a sound collecting cavity 31c, and a sound hole 311b is provided at the bottom of the sound collecting groove 31b, and the end of the sound hole 311b away from the sound collecting groove 31b is connected to the sound collecting cavity 31c, and the cavity wall of the sound collecting cavity 31c is provided with a sound guide hole 310c connected to the sound transmission section 105a, and the sound hole 311b, the sound collecting cavity 31c, and the sound guide hole 310c are connected in sequence to form the sound collecting section 101a.

[0086] It can be understood that by providing the sound collecting cavity 31c, the sound transmitted by the sound holes 311b can be collected and guided to the sound guide hole 310c for transmission to the microphone 11. When multiple sound holes 311b are provided, the sound collecting cavity 31c can simultaneously collect the sound transmitted by all the sound holes 311b and transmit it to a single sound guide hole 310c. The collected sound becomes louder, which can facilitate the collection of the sound by the microphone 11 and improve the sound quality of the collected heart sounds and / or lung sounds.

[0087] It should be noted that the number of the sound holes 311b can be 1, 2, 3, 4, 5, 6, etc. There is no limitation on the number of the sound holes 311b, and those skilled in the art can set them according to actual needs.

[0088] like Figures 3 to 5 As shown, in an embodiment of the wristband electronic device 100 of the present invention, a groove 31d is provided on the surface of the wristband 30 facing the wrist, the sound hole 311b is connected to the bottom wall of the groove 31d at one end away from the sound collecting groove 31b, the side wall of the groove 31d is provided with the sound guide hole 310c, and the opening of the groove 31d is covered with a cover plate 313, and the cover plate 313 is used to seal the groove 31d and enclose the groove wall of the groove 31d to form the sound collecting cavity 31c.

[0089] It is understandable that a cover plate 313 is provided at the opening of the groove 31d, and the cover plate 313 can seal the groove 31d, thereby facilitating the cleaning of the sound collecting cavity 31c. In addition, due to the relatively small thickness of the wristband 30, it would be difficult to form the sound collecting cavity 31c on the wristband 30 through an injection molding process. The wristband electronic device 100 of the present invention adopts a method of opening a groove 31d on the surface of the wristband 30 and sealing it with a cover plate 313, so that the cover plate 313 and the groove wall of the groove 31d enclose the sound collecting cavity 31c. This method can facilitate processing and manufacturing and reduce the difficulty of the process.

[0090] It should be noted that the cover plate 313 seals the groove 31d by sticking and fixing the cover plate 313 on the notch of the groove 31d with waterproof double-sided tape; or by sticking and fixing the cover plate 313 on the notch of the groove 31d with laser adhesive film; or other effective sealing methods can be used.

[0091] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
