Description

Technical Field

[0001] The present application relates to the field of smart wearable technology, and in particular to a magnetic device and electronic equipment. Background Art

[0002] As users' demands for the intelligence of electronic devices continue to increase, more and more functional components are installed in electronic devices, such as sensors such as gyroscopes and compasses. When charging, electronic devices usually need to use magnets on the electronic devices to ensure the stability of the connection between the electronic devices and the charging station. However, magnets on electronic devices can reduce the accuracy of sensors such as gyroscopes and compasses. Currently, relevant personnel usually prevent magnets from affecting the accuracy of sensors such as gyroscopes and compasses by setting a magnetic isolation sheet on one side of the magnet. However, due to the large magnetic resistance of the magnetic isolation sheet, the magnetic field will be reflected when passing through the magnetic isolation sheet, which results in unsatisfactory magnetic isolation effect of the magnetic isolation sheet.

The orthographic projections of the first and third sub-portions onto the magnet overlap the first magnetic shielding portion, while the orthographic projection of the second sub-portion onto the magnet is offset from the first magnetic shielding portion.

[0009] In some embodiments, the second magnetic isolation portion includes a layer of second magnetic isolation sheet. Alternatively, the second magnetic isolation portion includes multiple layers of second magnetic isolation sheets and second foam, with the second foam being disposed between two adjacent layers of the second magnetic isolation sheets.

The magnetic attraction device is housed within the housing. A magnetically sensitive element is mounted on the circuit board. The magnetic isolation member is located between the magnet and the magnetically sensitive element in the thickness direction of the circuit board.

[0011] In some embodiments, the housing has a stepped accommodating space comprising a first cavity and a second cavity that are interconnected, with the second cavity having a smaller opening than the first cavity.

[0037] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that the terms "center", "length", "up", "down", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In this application, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0041] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0042] As users’ requirements for the intelligence level of electronic devices continue to increase, more and more functional components are installed in electronic devices, such as sensors such as gyroscopes and compasses. When charging, electronic devices usually need to use magnets on the electronic devices to ensure the stability of the connection between the electronic devices and the charging station, but the magnets on the electronic devices will reduce the accuracy of sensors such as gyroscopes and compasses. At present, relevant personnel usually prevent magnets from affecting the accuracy of sensors such as gyroscopes and compasses by setting a magnetic isolation sheet on one side of the magnet. However, due to the large magnetic resistance of the magnetic isolation sheet, the magnetic field will be reflected when passing through the magnetic isolation sheet, which results in the magnetic isolation effect of the magnetic isolation sheet being unsatisfactory. Therefore, how to solve the problem of poor magnetic isolation effect of the magnetic isolation sheet due to the reflection of the magnetic field by the magnetic isolation sheet has become a difficult problem that those skilled in the art urgently need to solve. In order to solve these problems, the present application provides a magnetic suction device 100( Figures 1 to 3 As shown) and electronic device 1000 (as Figure 4 shown).

[0043] See also Figure 1 and Figure 2 The magnetic attraction device 100 of the embodiment of the present application includes a magnetic isolation member 10 and a magnet 20. The magnetic isolation member 10 is connected to one side of the magnet 20. The magnetic isolation member 10 includes a first magnetic isolation portion 101, which is connected to the magnet 20. The first magnetic isolation portion 101 includes multiple layers of first magnetic isolation sheets 1011 and first foam 1012. The first foam 1012 is provided between two adjacent layers of the first magnetic isolation sheets 1011.

[0044] Specifically, the magnetic device 100 is a device provided on various electronic devices 1000 that serves to fix the electronic device 100 to other components or to fix other components to the electronic device 1000. When the smart wearable device is charging or placed, the magnetic device 100 is used to fix the smart wearable device at its current position to prevent the smart wearable device from falling to the ground and being damaged. Among them, the smart wearable device can be a wearable device such as a smart watch or a sports bracelet. In the present application, the magnetic device 100 includes a magnetic isolation part 10 and a magnet 20. The magnet 20 can fix the smart wearable device on which the magnetic device 100 is installed on a metal surface to prevent the smart wearable device from slipping or falling to other locations. At the same time, a circuit board and various electronic components are also provided in the smart wearable device. In the circuit board or various electronic components, there are usually magnetically sensitive components. In order to prevent the magnet 20 from interfering with the operation of other magnetically sensitive components in the smart wearable device, a magnetic isolation part 10 is also provided on one side of the magnet 20.

[0045] More specifically, the magnetic isolation member 10 is a material used to reduce or block the influence of magnetic fields, and is used in various devices that need to protect sensitive components. The main function of the magnetic isolation member 10 is to prevent the external magnetic field from interfering with internal electronic components or to protect the external environment from being affected by the internal magnetic field. The materials of the magnetic isolation member 10 include three categories: metal materials, composite materials, and non-metallic materials. For example, the material of the magnetic isolation member 10 can be a metal material with strong shielding properties such as soft iron, nickel-iron alloy, and aluminum, or a conductive polymer with strong shielding properties, or a non-metallic material with strong shielding properties such as ferrite and conductive foam. The magnetic isolation member 10 includes a first magnetic isolation portion 101, and the first magnetic isolation portion 101 is connected to the magnet 20, thereby shielding the magnetic field of the magnet 20.

[0046] More specifically, if only one magnetic isolation sheet is used to isolate the magnet 20, the magnetic field of the magnet 20 will be reflected by the magnetic isolation sheet, and although it will be attenuated to a certain extent, it will still affect the magnetically sensitive components that need to be protected. Therefore, in the present application, the first magnetic isolation part 101 includes multiple layers of first magnetic isolation sheets 1011. The multiple layers of first magnetic isolation sheets 1011 will cause the magnetic field of the magnet 20 to be reflected and attenuated multiple times. Relevant personnel can set the number of layers of the first magnetic isolation sheets 1011 by themselves until the magnetic field of the magnet 20 cannot affect the magnetically sensitive components in the smart wearable device. The first magnetic isolation part 101 also includes multiple layers of first foam 1012. The first foam 1012 is arranged between two adjacent layers of the first magnetic isolation sheets 1011 to prevent the two adjacent layers of the first magnetic isolation sheets 1011 from contacting each other, to prevent the two adjacent layers of the first magnetic isolation sheets 1011 from merging into one layer of magnetic isolation sheets, to prevent the number of layers of the first magnetic isolation sheets 1011 from being reduced during use of the first magnetic isolation part 101, and to improve the stability of the magnetic isolation effect of the first magnetic isolation part 101.

[0047] It can be understood that the magnetic attraction device 100 of the present application includes a magnet 20 and a magnetic isolation member 10 connected to one side of the magnet 20, and the magnetic isolation member 10 includes a first magnetic isolation portion 101 connected to the magnet 20. The first magnetic isolation portion 101 includes multiple layers of first magnetic isolation sheets 1011 and a first foam 1012. The present application achieves multiple blocking of the magnetic field of the magnet 20 by arranging multiple layers of first magnetic isolation sheets 1011 in the first magnetic isolation portion 101. After encountering the first layer of magnetic isolation sheets, the magnetic field will attenuate and reflect. The next layer of magnetic isolation sheets will also block the reflected magnetic field again, and the magnetic field will further attenuate, thereby greatly reducing the influence of the reflected magnetic field on the accuracy of sensors such as gyroscopes and compasses. At the same time, the magnetic attraction device 100 of the present application can avoid contact between the magnetic isolation sheets by arranging a foam layer between the magnetic isolation sheets, thereby ensuring that the magnetic isolation member 10 has a better magnetic isolation effect as a whole.

[0048] See also Figure 2 and Figure 3In some application embodiments, the thickness of the first foam 1012 is greater than or equal to the thickness of the first magnetic isolation sheet 1011 .

[0049] Specifically, the first foam 1012 can enhance the physical protection of the first magnetic isolation sheet 1011. Specifically, when the user is using the smart wearable device, the smart wearable device will shake or vibrate with the user's movement. The elasticity and buffering properties of the first foam 1012 can effectively reduce the impact and vibration between the first magnetic isolation sheets 1011, and protect the first magnetic isolation sheet 1011 and the electronic components inside the smart wearable device from damage. In addition, the first foam 1012 can also serve as a buffer layer to reduce the wear between the first magnetic isolation sheets 1011 and extend the service life of the first magnetic isolation sheet 1011. For this reason, in the present application, the thickness of the first foam 1012 cannot be too thin. When the thickness of the first foam 1012 is greater than or equal to the thickness of the first magnetic isolation sheet 1011, the shock absorption and anti-wear effects of the first foam 1012 are better.

[0050] Specifically, the thickness of the first foam 1012 can create an additional space between two adjacent first magnetic shielding sheets 1011. If the distance between two adjacent first magnetic shielding sheets 1011 is too small, the magnetic field of the magnet 20 will interfere with each other when reflected between the multiple layers of first magnetic shielding sheets 1011. This mutual interference of the magnetic fields may increase the intensity of the magnetic field, which will reduce the overall magnetic shielding effect of the first magnetic shielding unit 101. Therefore, in the present application, the thickness of the first foam 1012 is greater than or equal to the thickness of the first magnetic shielding sheets 1011. The thicker first foam 1012 can increase the distance between two adjacent first magnetic shielding sheets 1011, reduce the magnetic field interference between the multiple layers of first magnetic shielding sheets 1011, and avoid affecting the magnetic shielding effect of the first magnetic shielding unit 101. In addition, the foam material has excellent chemical stability and can resist corrosion from various chemical substances. The first foam 1012 also has good temperature resistance and corrosion resistance. In extreme environments such as high temperature and high humidity, the first foam 1012 can also protect the function of the first magnetic shielding sheets 1011 from environmental influences.

[0051] See also Figure 2 and Figure 3 In some application embodiments, the orthographic projection of the first magnetic isolation sheet 1011 toward the magnet 20 coincides with the orthographic projection of the first foam 1012 toward the magnet 20 .

[0052] It is understood that in order to ensure the aesthetics of the first magnetic shielding portion 101 and to avoid excessive material waste during the production of the first magnetic shielding portion 101, relevant personnel need to ensure that the orthographic projection of the first magnetic shielding sheet 1011 onto the magnet 20 coincides with the orthographic projection of the first foam 1012 onto the magnet 20. At the same time, the first foam 1012 cannot be too small to ensure that the first foam 1012 fully isolates the two adjacent first magnetic shielding sheets 1011 and prevents the two adjacent first magnetic shielding sheets 1011 from contacting each other due to the shaking of the smart wearable device.

[0053] See also Figure 2 and Figure 3 In some application embodiments, the first magnetic isolation sheet 1011 covers the magnet 20 in its orthographic projection toward the magnet 20 , and the first foam 1012 covers the magnet 20 in its orthographic projection toward the magnet 20 .

[0054] It is understood that in order to ensure that the first magnetic shielding sheet 1011 can fully isolate the magnetic field of the magnet 20 and prevent the magnetic field of the magnet 20 from passing directly through the first magnetic shielding sheet 1011 without being blocked or isolated, the orthographic projection of the first magnetic shielding sheet 1011 toward the magnet 20 needs to cover the magnet 20. As can be seen from the previous embodiment, the orthographic projection of the first foam 1012 toward the magnet 20 coincides with the orthographic projection of the first magnetic shielding sheet 1011 toward the magnet 20, and the orthographic projection of the first foam 1012 toward the magnet 20 also covers the magnet 20.

[0055] See also Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present invention, the magnetic shielding member 10 further includes a second magnetic shielding portion 102, which is connected to the side of the first magnetic shielding portion 101 facing away from the magnet 20. The second magnetic shielding portion 102 includes a first sub-portion 1021, a second sub-portion 1022, and a third sub-portion 1023 connecting the first sub-portion 1021 and the second sub-portion 1022. The second sub-portion 1022 is further away from the magnet 20 than the first sub-portion 1021. The orthographic projections of the first sub-portion 1021 and the third sub-portion 1023 toward the magnet 20 cover the first magnetic shielding portion 101, and the orthographic projection of the second sub-portion 1022 toward the magnet 20 is offset from the first magnetic shielding portion 101.

[0056] Specifically, to further enhance the magnetic isolation effect of the magnetic isolation member 10, the magnetic isolation member 10 also includes a second magnetic isolation portion 102. The second magnetic isolation portion 102 is connected to the side of the first magnetic isolation portion 101 facing away from the magnet 20, thereby supplementing the magnetic isolation effect of the first magnetic isolation portion 101. The second magnetic isolation portion 102 includes a first sub-portion 1021, a second sub-portion 1022, and a third sub-portion 1023 connecting the first and second sub-portions 1021 and 1022. The second sub-portion 1022 is further away from the magnet 20 than the first sub-portion 1021.

[0057] More specifically, the orthographic projections of the first sub-section 1021 and the third sub-section 1023 toward the magnet 20 cover the first magnetic isolation section 101, since the orthographic projections of the first magnetic isolation section 101 toward the magnet 20 cover the magnet 20. Therefore, the orthographic projections of the first sub-section 1021 and the third sub-section 1023 toward the magnet 20 can also cover the magnet 20. This can ensure that the second magnetic isolation section 102 fully isolates the magnetic field generated by the magnet 20. At the same time, since the orthographic projections of the first sub-section 1021 and the third sub-section 1023 toward the magnet 20 cover the first magnetic isolation section 101, the magnetic field generated by the magnet 20 will be fully isolated and absorbed by the first sub-section 1021 and the third sub-section 1023 after being reflected by the first magnetic isolation section 101. In addition, considering the structure of the inner cavity of the electronic device 1000, the second sub-section 1022 is Figure 4 The electronic device 1000 is further away from the magnet 20 in the thickness direction Z. At the same time, since the second sub-portion 1022 needs to be connected to the inner surface of the first cavity 2011 of the shell 200, the orthographic projection of the second sub-portion 1022 toward the magnet 20 is staggered with the first magnetic isolation portion 101.

[0058] See also Figure 4 In some embodiments, the second magnetic isolation portion 102 includes a single layer of second magnetic isolation sheet (not shown). Alternatively, the second magnetic isolation portion 102 includes multiple layers of second magnetic isolation sheet (not shown) and second foam (not shown), with the second foam (not shown) disposed between two adjacent layers of second magnetic isolation sheet (not shown).

[0059] Specifically, to further enhance the magnetic isolation effect of the magnetic isolation member 10, the magnetic isolation member 10 further includes a second magnetic isolation portion 102. The second magnetic isolation portion 102 includes a second magnetic isolation sheet (not shown). The second magnetic isolation sheet (not shown) can isolate the remaining reflected magnetic field of the magnet 20 passing through the first magnetic isolation portion 101, thereby supplementing the magnetic isolation effect of the first magnetic isolation portion 101.

[0060] More specifically, the second magnetic isolation part 102 may also include multiple layers of second magnetic isolation sheets (not shown in the figure) and second foam (not shown in the figure). Similarly, if only one magnetic isolation sheet is used to isolate the remaining reflected magnetic field of the magnet 20 passing through the first magnetic isolation part 101, the remaining reflected magnetic field of the magnet 20 passing through the first magnetic isolation part 101 will be reflected again by the magnetic isolation sheet. Although there will be a certain attenuation, it will still affect the magnetic sensitive components that need to be protected. Therefore, in the present application, the second magnetic isolation part 102 includes multiple layers of second magnetic isolation sheets (not shown in the figure). The multiple layers of second magnetic isolation sheets (not shown in the figure) will cause the remaining reflected magnetic field of the magnet 20 passing through the first magnetic isolation part 101 to be reflected and attenuated multiple times. Relevant personnel can set the number of layers of the second magnetic isolation sheet (not shown in the figure) by themselves until the remaining reflected magnetic field of the magnet 20 passing through the first magnetic isolation part 101 cannot affect the magnetic sensitive components in the smart wearable device. The second magnetic isolation part 102 also includes multiple layers of second foam (not shown in the figure). A second foam (not shown in the figure) is arranged between two adjacent layers of the second magnetic isolation sheets (not shown in the figure) to prevent the two adjacent layers of the second magnetic isolation sheets (not shown in the figure) from contacting each other, to prevent the two adjacent layers of the second magnetic isolation sheets (not shown in the figure) from merging into one layer of magnetic isolation sheets, to avoid the situation where the number of layers of the second magnetic isolation sheets (not shown in the figure) in the second magnetic isolation part 102 is reduced during use, and to improve the stability of the magnetic isolation effect of the second magnetic isolation part 102.

[0061] In summary, the magnetic attraction device 100 of the present application includes a magnetic isolation member 10 and a magnet 20 connected to one side of the magnet, and the magnetic isolation member 10 includes a first magnetic isolation portion 101 connected to the magnet 20. The first magnetic isolation portion 101 includes multiple layers of first magnetic isolation sheets 1011 and a first foam 1012. The present application achieves multiple blocking of the magnetic field of the magnet 20 by arranging multiple layers of first magnetic isolation sheets 1011 in the first magnetic isolation portion 101. After encountering the first layer of magnetic isolation sheets, the magnetic field will attenuate and reflect. The next layer of magnetic isolation sheets will also block the reflected magnetic field again, and the magnetic field will further attenuate, thereby greatly reducing the influence of the reflected magnetic field on the accuracy of sensors such as gyroscopes and compasses. At the same time, the present application avoids contact between the magnetic isolation sheets by arranging a foam layer between the magnetic isolation sheets, thereby avoiding affecting the overall magnetic isolation effect of the magnetic isolation member 10.

[0062] See also Figure 4 The electronic device 1000 according to an embodiment of the present application includes a housing 200, a magnetic device 100 housed within the housing 200, and a circuit board 30 housed within the housing 200. The magnetic device 100 is any of the magnetic devices 100 described above. A magnetically sensitive element 301 is mounted on the circuit board 30. In the thickness direction Z of the circuit board 30, the magnetic isolation member 10 is located between the magnet 20 and the magnetically sensitive element 301.

[0063] Specifically, the electronic device 1000 includes a shell 200, which is a structure for loading various internal components of the electronic device 1000. The shell 200 plays the role of protecting and supporting the electronic device 1000, while also being able to maintain the beauty of the electronic device 1000. The shell 200 can be made of plastic (such as polypropylene or polycarbonate, etc.), metal (such as aluminum, stainless steel and magnesium alloy, etc.) and composite materials (such as carbon fiber or composite plastic, etc.). The magnetic attraction device 100 and the circuit board 30 are both accommodated in the shell 200. The circuit board 30 is an internal structure for realizing the corresponding functions of the electronic device 1000. A magnetic sensitive element 301 is provided on the circuit board 30. Therefore, when a magnet 20 is provided in the electronic device 1000, the magnetic sensitive element 301 requires magnetic isolation protection of the first magnetic isolation part 101 and the second magnetic isolation part 102. The magnetic attraction device 100 is a device provided on various electronic devices 1000 to fix the electronic device 100 to other components or to fix other components to the electronic device 1000. When the electronic device 1000 is being charged or placed, the magnetic device 100 is used to fix the electronic device 1000 at its current position to prevent the electronic device 1000 from falling to the ground and being damaged.

[0064] More specifically, the housing 200 can prevent dust, moisture, chemicals and physical impact from damaging the internal circuits and components of the electronic device 1000, and provide fixation and support for the internal components of the electronic device 1000, preventing the internal circuits and components of the electronic device 1000 from shifting during transportation or user use. In addition, when the constituent material of the housing 200 is metal, the housing 200 has strong heat dissipation properties, which can help the internal circuits and components of the electronic device 1000 maintain a suitable operating temperature and prevent the internal circuits and components of the electronic device 1000 from overheating. At the same time, the metal housing 200 can effectively shield external electromagnetic interference and protect the normal operation of the internal circuits and components of the electronic device 1000. Manufacturers can also design the appearance of the housing 200 to ensure that users have a good first impression of the electronic device 1000 and enhance the product market competitiveness of the electronic device 1000.

[0065] In some embodiments, please combine Figure 4 The electronic device 1000 includes at least one of a watch, an earphone, a bracelet, a mobile phone, a tablet computer and a laptop computer.

[0066] It is understandable that in the present application, the electronic device 1000 can be any device having a housing and a circuit board 30 inside, for example: the electronic device 1000 can be any smart wearable device having a housing and a circuit board 30 inside. More specifically, the electronic device 1000 includes at least one of a watch, earphones, a bracelet, a mobile phone, a tablet computer and a laptop computer. The magnetic device 100 is provided on a watch, earphones, a bracelet, a mobile phone, a tablet computer or a laptop computer to fix the electronic device 1000, such as a watch, earphones, a bracelet, a mobile phone, a tablet computer or a laptop computer, in a charging position or a placement position when the watch, earphones, a bracelet, a mobile phone, a tablet computer or a laptop computer is being charged or placed, so as to prevent the watch, earphones, a bracelet, a mobile phone, a tablet computer or a laptop computer from falling to the ground and being damaged.

[0067] In certain embodiments, see Figures 3 to 5 The shell 200 is provided with a stepped accommodating space 201, and the accommodating space 201 includes a first cavity 2011 and a second cavity 2013 that are connected. The opening of the second cavity 2013 is smaller than the opening of the first cavity 2011. The circuit board 30 and the second sub-portion 1022 of the second magnetic isolation portion 102 of the magnetic attraction device 100 are accommodated in the first cavity 2011, and the first magnetic isolation portion 101, the magnet 20 and the first sub-portion 1021 of the second magnetic isolation portion 102 are accommodated in the second cavity 2013. The third sub-portion 1023 of the second magnetic isolation portion 102 is arc-shaped and matched with the stepped connection of the inner wall of the accommodating space 201.

[0068] Specifically, since the interior of the housing 200 needs to accommodate the magnetic device 100 and the circuit board 30, in the present application, the housing 200 is provided with a stepped accommodation space 201. The accommodation space 201 is configured in a stepped shape, thereby dividing itself into a first cavity 2011 and a second cavity 2013. A certain distance needs to be left between the location where the magnet 20 in the magnetic device 100 is set and the location where the circuit board 30 is set to weaken the magnetic field at the location where the circuit board 30 is set. At the same time, the space between the location where the magnet 20 is set and the location where the circuit board 30 is set can also be used to place the first magnetic isolation portion 101, the second magnetic isolation portion 102, and other internal components of the electronic device 1000, such as an energy storage battery. The opening of the second cavity 2013 is smaller than that of the first cavity 2011, that is, compared with the second cavity 2013, the first cavity 2011 can accommodate larger objects. The circuit board 30, the second sub-portion 1022 of the second magnetic isolation portion 102 of the magnetic attraction device 100 are housed in the first cavity 2011, and the first magnetic isolation portion 101, the magnet 20, and the first sub-portion 1021 of the second magnetic isolation portion 102 are housed in the second cavity 2013. This ensures that the first and second magnetic isolation portions 101 and 102 can fully isolate the magnetic field of the magnet 20, preventing the magnetic field of the magnet 20 from affecting the magnetic sensitive element 301 on the circuit board 30 and the magnet 20 from affecting the overall function of the electronic device 1000. The third sub-portion 1023 of the second magnetic isolation portion 102 is aligned with the stepped connection of the inner wall of the accommodating space 201 at an arc shape. This reduces the shaking of the second magnetic isolation portion 102 within the electronic device 1000 during use, prevents the second magnetic isolation portion 102 from moving away from its original position, and prevents the magnetic isolation effect of the second magnetic isolation portion 102 from being affected, thereby enhancing the durability of the electronic device 1000.

[0069] More specifically, the present application accommodates the first subsection 1021 of the second magnetic isolation portion 102 within the second cavity 2013, thereby leaving a larger volume of space for the first cavity 2011. This allows the first cavity 2011 to accommodate more devices and electronic components, thereby supporting the electronic device 1000 in achieving more functions. For example, the first cavity 2011 of the electronic device 1000 can be equipped with a heart rate monitor, a barometer, a storage battery, a positioning device, a built-in antenna, a vibration motor, a speaker, a health monitoring module, a microphone, a Bluetooth device, an accelerometer, a gyroscope, and a temperature sensor.

[0070] In certain embodiments, see Figure 4 and Figure 5A backing adhesive layer (not shown) is provided on a side of the second magnetic isolation portion 102 of the magnetic isolation member 10 close to the inner surface of the housing 200. The backing adhesive layer (not shown) is used to connect the second sub-portion 1022 of the second magnetic isolation portion 102 to the inner surface of the housing 200. And / or, a connecting hole 40 is provided on one of the second magnetic isolation portion 102 of the magnetic isolation member 10 and the inner surface of the housing 200, and a connecting post 50 is provided on the other, and the connecting post 50 is engaged with the connecting hole 40.

[0071] Specifically, to prevent the second magnetic shielding portion 102 of the magnetic shielding member 10 from moving from its original position, thereby reducing the magnetic shielding effect of the second magnetic shielding portion 102 and enhancing the durability of the electronic device 1000, an adhesive layer (not shown) is provided on the side of the second magnetic shielding portion 102 adjacent to the inner surface of the housing 200. This adhesive layer (not shown) securely adheres the second magnetic shielding portion 102 to the inner surface of the housing 200, preventing the second magnetic shielding portion 102 from moving from its original position due to shaking during use of the electronic device 1000. Furthermore, one of the second magnetic shielding portion 102 and the inner surface of the housing 200 may be provided with a connecting hole 40, while the other may be provided with a connecting post 50. The engagement of the connecting post 50 with the connecting hole 40 reduces the amplitude of shaking of the second magnetic shielding portion 102 during use of the electronic device 1000, thereby preventing the second magnetic shielding portion 102 from moving from its original position and reducing the magnetic shielding effect of the second magnetic shielding portion 102, thereby enhancing the durability of the electronic device 1000.

[0072] More specifically, the adhesive layer (not shown) is a material layer used to secure and bond various components, playing a crucial role in the assembly and maintenance of electronic device 1000. The adhesive layer (not shown) not only affects the performance of electronic device 1000 but also its durability and long-term stability. Materials for the adhesive layer (not shown) can include acrylic adhesive, polyurethane adhesive, hot melt adhesive, double-sided tape, and the like.

[0073] In summary, the electronic device 1000 of the present application includes a housing 200, a magnetic attraction device 100 housed in the housing 200, and a circuit board 30 housed in the housing 200. The magnetic attraction device 100 includes a magnet 20 and a magnetic isolation member 10 connected to one side of the magnet. The magnetic isolation member 10 includes a first magnetic isolation portion 101 connected to the magnet 20. The first magnetic isolation portion 101 includes multiple layers of first magnetic isolation sheets 1011 and a first foam 1012. The present application achieves multiple blocking of the magnetic field of the magnet 20 by arranging multiple layers of first magnetic isolation sheets 1011 in the first magnetic isolation portion 101. After encountering the first layer of magnetic isolation sheets, the magnetic field will attenuate and generate reflection. The next layer of magnetic isolation sheets will also block the reflected magnetic field again, and the magnetic field will further attenuate, thereby greatly reducing the influence of the reflected magnetic field on the accuracy of sensors such as gyroscopes and compasses. At the same time, the present application avoids contact between the magnetic isolation sheets by arranging a foam layer between the magnetic isolation sheets, thereby avoiding affecting the overall magnetic isolation effect of the magnetic isolation member 10.
