Description

Terminal Equipment

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 18, 2022, with application number 202223096869.X and application name “Terminal Device”, all contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the technical field of terminal devices, and more specifically, to a foldable terminal device.

Background technique

Flexible screens have the property of being bendable and have been used in foldable terminal devices such as mobile phones, tablets, bracelets, game consoles, and wearable devices. In order to offset the impact of the rebound force of the flexible screen, magnets need to be arranged in the foldable terminal device to achieve tight attraction of the entire device when it is folded. In addition, in order to evenly distribute the magnetic attraction generated by the magnets around the device when it is attracted, so that the user can feel better when opening and closing the device, the current magnet layout of foldable terminal devices tends to be more numerous and evenly distributed.

Since terminal devices generally have devices such as compasses, Hall devices, and magnetoresistive devices that are very sensitive to magnetic field strength, if the layout of such magnetically sensitive devices and the magnets used to attract the terminal devices is unreasonable, the magnetically sensitive devices will easily be disturbed by the magnetic field generated by the magnets, which will lead to problems such as failure of the magnetically sensitive devices or poor working accuracy.

Detailed ways

The following is an exemplary introduction to the relevant contents that may be involved in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or parts as an example. It should be understood that the figure mark also applies to other identical parts or parts.

In the description of this application, it should be noted that the term "and/or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

Flexible screens are bendable and have been used in foldable devices such as mobile phones, tablets, bracelets, game consoles, and wearable devices. The screens of such devices can increase the display size without increasing the volume, and also have a high screen-to-body ratio and clarity. For example, a foldable phone can be as small as a traditional phone after folding, making it easy to carry, but can be as large as a tablet computer after unfolding. These features make foldable devices popular among consumers.

In order to offset the rebound force of the flexible screen after the device is folded, magnets need to be arranged in the foldable terminal device to achieve a tight suction of the entire device when folded. In addition, in order to evenly distribute the magnetic attraction generated by the magnets around the device when it is sucked, so that the user can feel better when opening and closing the device, and avoid the situation where the hand feeling is strong in some places and weak in other places, based on this situation, the current layout of magnets in foldable terminal devices tends to be more numerous and evenly distributed.

Since terminal devices generally have compasses, Hall devices, magnetoresistive devices, etc. that are very sensitive to magnetic field strength If the layout of such magnetic sensitive devices and the magnets used to attract the terminal equipment is unreasonable, the magnetic sensitive devices will be easily disturbed by the magnetic field generated by the magnets, which will lead to problems such as failure of the function of the magnetic sensitive devices or poor working accuracy.

In order to solve the above technical problems, the present application provides a terminal device. By setting the magnetic field directions of the first magnetic component and the second magnetic component to be opposite, a specific area with a low magnetic field or a zero magnetic field can be generated between the first magnetic component and the second magnetic component. Magnetic sensitive devices such as compasses, Hall devices, and magnetoresistive devices are set in the specific area to ensure the normal operation of the devices.

The terminal device provided by the present application is now described in detail with reference to the accompanying drawings.

FIG1 is a schematic diagram of a terminal device provided in an embodiment of the present application. FIG2 is a schematic diagram of an example of a magnetic suction module and a magnetic sensitive device 50 provided in an embodiment of the present application inside a terminal device. FIG3 is a schematic diagram of another example of a magnetic suction module and a magnetic sensitive device provided in an embodiment of the present application inside a terminal device. FIG4 is a schematic diagram of the terminal device in FIG3 in a folded state. FIG5 is a schematic diagram of the distribution of magnetic flux lines of the first magnetic suction module 40 in FIG3.

As shown in Figures 1 to 5, a terminal device provided in an embodiment of the present application includes a screen 31 and two bodies for carrying the screen 31, namely a first body 10 and a second body 20. A hinge assembly 30 is provided at the junction of the first body 10 and the second body 20 so that the first body 10 and the second body 20 can switch between a folded state and an unfolded state.

A first magnetic module 40 and a second magnetic module 70 are respectively disposed at sides of the first body 10 and the second body 20 away from the hinge assembly 30 . When the first body 10 and the second body 20 are in a folded state, the first magnetic module 40 and the second magnetic module 70 are attracted to each other.

The first magnetic attraction module 40 includes a first magnetic component 41 and a second magnetic component 42 which are spaced apart along the side. A magnetic sensitive device 50 is provided in the area of the first body 10 between the first magnetic component 41 and the second magnetic component 42. At the magnetic sensitive device 50, the direction of the magnetic field generated by the first magnetic component 41 is opposite to the direction of the magnetic field generated by the second magnetic component 42.

Generally speaking, if the magnetic field directions of the first magnetic component 41 and the second magnetic component 42 remain consistent, the magnetic field at the magnetic sensitive device 50 will be superimposed, and the magnetic field intensity is high, exceeding the environmental magnetic field requirement of the magnetic sensitive device 50. The key point in the embodiment of the present application is that the magnetic fields formed by the first magnetic component 41 and the second magnetic component 42 on both sides of the magnetic sensitive device 50 are in opposite directions, so as to provide a safe magnetic environment for the magnetic sensitive device 50.

Specifically, as shown in Figure 5, the terminal device in the embodiment of the present application sets the magnetic sensitive device 50 in a specific area M1 between the second magnetic part 42 and the first magnetic part 41, and in the specific area M1, the direction of the magnetic field generated by the first magnetic part 41 is opposite to the direction of the magnetic field generated by the second magnetic part 42, thereby adjusting the factors affecting the magnetic field strength such as the spacing, material, volume, shape, etc. between the first magnetic part 41 and the second magnetic part 42, thereby debugging and forming an environmental magnetic field condition with low magnetic field strength or zero magnetic field strength in the specific area M1, thereby preventing the magnetic sensitive device 50 set in the specific area M1 from being affected by the magnetic fields of the first magnetic part 41 and the second magnetic part 42, thereby ensuring that the magnetic sensitive devices 50 such as compasses, Hall devices, and magnetoresistive devices can work normally, so that the corresponding functions on the terminal device can be effective and the working accuracy is guaranteed.

Optionally, the terminal device includes but is not limited to a foldable mobile phone, a foldable tablet, a foldable bracelet, a foldable wearable device, etc.

Optionally, the screen 31 may be a flexible screen that is foldable as a whole; or, the screen 31 may be a combination of a foldable flexible screen in the middle area and rigid screens at both ends, which is not limited in this application.

Optionally, the terminal device may further include multiple modules, and the multiple modules may be stored inside the two fuselages. The multiple modules of the terminal device may include but are not limited to a motherboard, a processor, a memory, a battery 62, a camera module 66, an audio module 67, a The barrel module, speaker module, microphone module, antenna module, sensor module, etc. The embodiment of the present application does not specifically limit the number, type, position, etc. of the modules of the terminal device.

Optionally, the magnetic sensitive device 50 includes but is not limited to a compass, a Hall device, a magnetoresistive device, etc.

Specifically, the compass in the terminal device is also called an electronic compass, which is used in the terminal device as a navigation instrument or an attitude sensor. Its function can be realized by a sensor that responds to the earth's magnetic field, such as a magnetic sensor.

Specifically, the Hall device is an electrical component made using the Hall effect. When a metal or semiconductor sheet with current flowing through it is placed vertically in a magnetic field, a potential difference will be generated at both ends of the sheet. This phenomenon is called the Hall effect. The Hall device belongs to this type of active magnetoelectric conversion device. It is made based on the principle of the Hall effect and uses integrated packaging and assembly technology. It can easily convert magnetic input signals into electrical signals for practical applications.

Specifically, magnetoresistive devices are electrical components made using the magnetoresistive effect. The phenomenon that the resistance of a substance changes in a magnetic field is called the magnetoresistive effect. They are also electrical components that convert magnetic input signals into electrical signals for practical applications.

Optionally, the magnetic sensitive device 50 may also include a speaker module. The speaker is usually composed of a sound membrane and a coil made of conductive material. The speaker has its own magnetic field formed inside. When an electrical signal carrying sound characteristics is passed into the coil, the coil will be affected by the magnetic field force and vibrate, thereby driving the sound membrane to vibrate and then make a sound, thereby achieving the purpose of converting the electrical signal into sound. If the coil is disturbed by the magnetic field force formed by the first magnetic module 40, the vibration of the sound membrane will become unstable, causing the sound quality of the speaker to be distorted. Therefore, on some terminal devices that pursue extreme sound quality, the first magnetic module 40 should also avoid interfering with the speaker, and the above purpose can be achieved by adopting the layout of the first magnetic module 40 and the speaker module in the embodiment of the present application.

Optionally, the magnetic sensitive device 50 may be directly disposed on the mainboard; or, the magnetic sensitive device 50 may be disposed on the flexible circuit board 64; or, the magnetic sensitive device 50 may be disposed on other circuit boards and then connected to the mainboard through the flexible circuit board 64. For a more detailed description, please refer to the following embodiments.

Optionally, the first magnetic module 40 can be fixed in a receiving groove 114 provided on the first body 10 ; or, the first magnetic module 40 can be fixed on an inner surface of the first body 10 .

Optionally, the materials of the first magnetic member 41 and the second magnetic member 42 include but are not limited to samarium cobalt magnets, neodymium iron boron magnets, ferrite magnets, aluminum nickel cobalt magnets, and iron chromium cobalt magnets.

Optionally, the structures of the magnetic modules on the two bodies may be the same. For example, as shown in FIG. 3 or 4, the first magnetic module 40 composed of multiple magnetic parts (a first magnetic part 41 and a second magnetic part 42) provided on the first body 10 is the same as the second magnetic module 70 composed of multiple magnetic parts provided on the second body 20.

It should be noted that the material and layout of the multiple magnetic parts arranged on the second body 20 should be the same as those of the first magnetic attraction module 40, so that the second magnetic attraction module 70 can also form a specific area with low magnetic field intensity or zero magnetic field intensity, so that when the second body 20 is in a folded state, the second magnetic attraction module 70 will not interfere with the magnetic sensitive device 50.

Optionally, the structures of the magnetic modules on the two bodies may be different. For example, as shown in Figure 2, the first magnetic module 40 composed of multiple magnetic parts (first magnetic part 41 and second magnetic part 42) arranged on the first body 10 is different from the second magnetic module 70 which is a whole piece arranged on the second body 20.

It should be noted that in this case, the material of the second magnetic attraction module 70 is made of metal material that can be attracted by the first magnetic attraction module 40, such as metals such as iron, cobalt and nickel, so that the second magnetic attraction module 70 will not form a magnetic field, and will not interfere with the magnetic sensitive device 50 when the second body 20 is in the folded state.

When the first magnetic attraction module 40 only has the first magnetic member 41 and the second magnetic member 42, the specific area M1 can only be located on the line between the first magnetic member 41 and the second magnetic member 42. This is because the first magnetic member 41 and the second magnetic member 42 are In addition to its own magnetic circuit, 42 may also have a magnetic circuit formed by the coupling of the first magnetic component 41 and the second magnetic component 42. For example, as shown in FIG5 , above and below the specific area M1, there may be a magnetic circuit formed by the coupling of the first magnetic component 41 and the second magnetic component 42, where there is a certain magnetic field strength.

In this case, the specific area M1 is relatively small, so that the layout flexibility of the magnetic sensitive device 50 is relatively low and can only be arranged within a limited range, which is not conducive to the overall structure optimization of the terminal device.

Therefore, in order to solve the above problem, it is possible to consider adding the magnetic parts of the first magnetic attraction module 40 in pairs to offset the magnetic fields above and below the specific area M1 in FIG5 , thereby increasing the range of the specific area M1 to make the layout range of the magnetic sensitive device 50 larger and more flexible. For a more detailed description, please refer to the embodiments described below.

Fig. 6 is a schematic diagram of another example of a magnetic attraction module and a magnetic sensitive device 50 provided in an embodiment of the present application inside a terminal device. Fig. 7 is a schematic diagram of the terminal device in Fig. 6 in a folded state. Fig. 8 is a schematic diagram of the magnetic flux distribution of the magnetic attraction module in Fig. 9.

As shown in Figures 6-8, in an embodiment provided in the present application, the first magnetic attraction module 40 also includes a third magnetic component 43 and a fourth magnetic component 44, and the third magnetic component 43, the first magnetic component 41, the second magnetic component 42 and the fourth magnetic component 44 are arranged in sequence along the side; the third magnetic component 43 has opposite magnetism to the first magnetic component 41, the first magnetic component 41 has opposite magnetism to the second magnetic component 42, and the second magnetic component 42 has opposite magnetism to the fourth magnetic component 44.

In this embodiment, the third magnetic component 43 and the fourth magnetic component 44 on the outermost sides can be coupled to form a magnetic circuit, and the first magnetic component 41 and the second magnetic component 42 on the innermost sides can be coupled to form a reverse magnetic circuit. The directions of the two parts of the magnetic field are just opposite and can offset the magnetic field. Therefore, the specific area with low magnetic field strength or zero magnetic field strength is no longer limited to the connecting line between the first magnetic component 41 and the second magnetic component 42, so that the range of the specific area is expanded.

For ease of understanding, by comparing the specific area M1 in FIG. 5 and the specific area M2 in FIG. 8 , it can be seen that the specific area M2 of low magnetic field strength or zero magnetic field strength in this embodiment is expanded compared to the specific area M1 in FIG. 5 , and the magnetic sensitive device 50 can be arranged in the specific area M2, so that the layout design of the magnetic sensitive device 50 in this embodiment is more flexible, which is beneficial to the overall structure optimization of the terminal device.

As can be seen from Figures 5 and 8, regardless of whether the first magnetic attraction module 40 includes the third magnetic component 43 and the fourth magnetic component 44, the connection between the first magnetic component 41 and the second magnetic component 42 can be adjusted to a specific area with low magnetic field strength or zero magnetic field strength. Therefore, as shown in Figures 9, 10, and 17, in this embodiment, it is a more reasonable layout to arrange the magnetic sensitive device 50 at the edge of the bottom wall 111 close to the side wall section 112a, that is, closer to the connection between the first magnetic component 41 and the second magnetic component 42.

Optionally, the first body 10 further includes a back cover 12, which covers the middle frame 11 opposite to the screen 31. The back cover 12, the middle frame 11 and the screen 31 together form a closed space for installing various modules of the terminal device.

Optionally, the terminal device further includes a camera module 66 and a camera decoration 67. The camera decoration 67 It is mainly used to protect the camera module 66 and also serves to decorate the appearance of the terminal device.

In addition, the magnetic sensitive device 50 is disposed on the first circuit board 61 at an edge close to the side wall section 112a, that is, closer to the connection line between the first magnetic member 41 and the second magnetic member 42, so that the magnetic sensitive device 50 is placed in a specific area with low magnetic field strength or zero magnetic field strength.

Fig. 13 is a schematic diagram of another installation example of the magnetic sensor device 50 provided in the embodiment of the present application. Fig. 14 is an enlarged view of point B in Fig. 13 .

That is, in an embodiment provided in the present application, as shown in Figures 9, 13, and 14, a partition wall 113 is provided on the bottom wall 111 to divide the bottom wall 111 into a battery placement area 111a and a circuit board placement area 111b. A first circuit board 61 is provided in the circuit board placement area 111b, and a battery 62 and a second circuit board 63 are provided in the battery placement area 111a.

In this embodiment, the first circuit board 61 may be the main board of the terminal device, the second circuit board 63 may be the charging protection board of the battery 62, the magnetic sensitive device 50 is welded on the second circuit board 63, and then the second circuit board 63 is electrically connected to the first circuit board 61 through the flexible circuit board 64. In addition, the magnetic sensitive device 50 is arranged on the second circuit board 63 at the edge close to the side wall section 112a, that is, closer to the connection between the first magnetic member 41 and the second magnetic member 42, so that the magnetic sensitive device 50 is placed in a specific area with low magnetic field strength or zero magnetic field strength.

Fig. 15 is a schematic diagram of another installation example of the magnetic sensor device 50 provided in an embodiment of the present application. Fig. 16 is an enlarged view of point C in Fig. 15 .

As mentioned above, the magnetic sensitive device 50 can be arranged on the flexible circuit board 64, that is, as shown in one embodiment provided in the present application, a partition wall 113 is provided on the bottom wall 111 to divide the bottom wall 111 into a battery placement area 111a and a circuit board placement area 111b, and a first circuit board 61 is provided in the circuit board placement area 111b, and a battery 62 and a second circuit board 63 are provided in the battery placement area 111a, and the second circuit board 63 is electrically connected to the first circuit board 61 through the flexible circuit board 64; the flexible circuit board 64 is located at the edge of the bottom wall 111 close to the side wall section 112a, and the magnetic sensitive device 50 is provided on the flexible circuit board 64.

In this embodiment, the first circuit board 61 may be the main board of the terminal device, the second circuit board 63 may be the charging protection board of the battery 62, the second circuit board 63 is electrically connected to the first circuit board 61 through the flexible circuit board 64, and the magnetic sensitive device 50 is welded on the flexible circuit board 64. In addition, the flexible circuit board 64 is located at the edge of the bottom wall 111 close to the side wall section 112a, that is, the magnetic sensitive device 50 located on the flexible circuit board 64 can be closer to the connection line between the first magnetic member 41 and the second magnetic member 42, so that the magnetic sensitive device 50 is placed in a specific area with low magnetic field strength or zero magnetic field strength.

Since the magnetic sensor 50 itself has a certain weight, if it is welded in the middle of the flexible circuit board 64 in a suspended state, when the terminal device vibrates during use, the magnetic sensor 50 will swing up and down due to inertia, which is not conducive to the stability of the connection at the welding point. More importantly, when the magnetic sensor 50 is a compass, the position movement of the magnetic sensor 50 will lead to inaccurate position measurement. Therefore, the magnetic sensor 50 should be relatively fixed to the first circuit board 61 or the second circuit board 63 as much as possible. The specific embodiment is described below.

As shown in FIG. 16 , in an embodiment provided in the present application, the two ends of the flexible circuit board 64 are electrically connected to the first circuit board 61 and the second circuit board 63 respectively, and the magnetic sensitive device 50 is located at the end of the flexible circuit board 64 closer to the second circuit board 63 .

In another embodiment provided by the present application, the magnetic sensitive device 50 is located at an end of the flexible circuit board 64 that is closer to the first circuit board 61 .

In the above two embodiments, the relative position of the magnetic sensitive device 50 and the first circuit board 61 or the second circuit board 63 can be fixed, which is beneficial to the working accuracy of the sensitive device. In addition, it is also beneficial to the connection stability of the welding point and increases the shock resistance of the magnetic sensitive device 50.

As mentioned above, the first magnetic attraction module 40 can be fixed in the receiving groove 114 opened on the first body 10, that is, in an embodiment provided in the present application, as shown in Figure 10, a receiving groove 114 is provided on the surface of the side of the bottom wall 111 away from the magnetic sensitive device 50, and the receiving groove 114 is located at the edge of the side of the bottom wall 111 away from the rotating shaft assembly 30, and the receiving groove 114 extends along the groove depth direction to the interior of the first side wall 112, and the first magnetic attraction module 40 is arranged in the receiving groove 114.

In this embodiment, the first magnetic attraction module 40 is arranged in a receiving groove 114 on the side surface of the bottom wall 111 facing away from the magnetic sensitive device 50, so that the receiving groove 114 can form a magnetic shielding effect on the first magnetic attraction module 40, which can further prevent the first magnetic attraction module 40 from interfering with the magnetic sensitive device 50.

Optionally, the first magnetic attraction module 40 and the groove wall of the receiving groove 114 can be bonded with adhesive, snap-fitted, bolted, etc., or the first magnetic attraction module 40 can be directly fixed by supporting the groove wall of the receiving groove 114.

Optionally, when the size of the receiving groove 114 is relatively large, the first magnetic attraction module 40 may be packaged in the receiving groove 114 by plastic casting.

It should be noted that the first magnetic module 40 and the receiving slot 114 can be fixedly connected in various ways and are not limited to the above-mentioned methods.

Optionally, the receiving groove 114 may be a long strip-shaped groove, and all magnetic components are fixed in one groove; or, the receiving groove 114 is composed of a plurality of unit grooves, and each magnetic component is correspondingly fixed in one unit groove.

It should be noted that the connection method or connection structure between the second magnetic module 70 and the second body 20 is the same as the connection method or connection structure between the first magnetic module 40 and the first body 10, and will not be repeated here.

FIG18 is a schematic diagram of the terminal device in FIG17 when it is in a folded state.

As shown in Figure 17, in an embodiment provided in the present application, the second body 20 includes a first device 65 having a magnetic component, the edge of the side of the second body 20 away from the hinge assembly 30 is a second side wall 22, and the edge of the side close to the hinge assembly 30 is a third side wall 23; the distance from the first device 65 to the second side wall 22 is greater than or equal to the distance from the first device 65 to the third side wall 23.

In this embodiment, the distance L from the first device 65 to the second side wall 22 is greater than or equal to the distance d from the first device 65 to the third side wall 23, so that the first device 65 with a magnetic component is closer to the hinge assembly 30, so that when the terminal device is in a folded state, as shown in FIG. 18, the first device 65 can be kept away from the first magnetic suction module 40 and the magnetic sensitive device 50, thereby preventing the magnetic field generated by the first device 65 from interfering with the magnetic sensitive device 50, thereby ensuring that the terminal device In the folded state, the magnetic sensor 50 can also maintain stability and working accuracy.

Among them, the above-mentioned avoidance of the magnetic field generated by the first device 65 from interfering with the magnetic sensitive device 50 is mainly achieved through two ways. One is that the magnetic field generated by the first device 65 avoids directly interfering with the magnetic sensitive device 50, and the other is that the magnetic field generated by the first device 65 avoids interfering with the first magnetic suction module 40, thereby preventing the environmental magnetic field conditions of low magnetic field intensity or zero magnetic field intensity that have been constructed by the first magnetic suction module 40 from being destroyed, thereby avoiding the first device 65 from indirectly interfering with the magnetic sensitive device 50.

As shown in FIG. 19 , when the terminal device is in the folded state, the magnetic field strength in region F is 0, and the magnetic sensitive device 50 disposed in region F will not be disturbed by the first magnetic attraction module 40 and the magnetic components of the first device 65 .

In an embodiment provided in the present application, the first device 65 includes a speaker, a vibration motor, and a microphone.

Both the speaker and the vibration motor have magnetic components inside. The magnetic component of the speaker is a magnet that provides magnetic field force for the energized coil, and the magnetic component of the vibration motor is a stator that generates a rotating magnetic field.

In addition, the microphone also has a magnetic component, which is composed of a magnet and a film coil. The working principle is that the sound drives the film coil to vibrate through the air, and under the action of the magnet, magnetic lines of force are cut to generate a weak current, thereby realizing the conversion of sound into electricity.

Optionally, when the terminal device is a mobile phone, the speaker may be an upper speaker or a lower speaker.

Optionally, in addition to the above-mentioned cases, the first device 65 may also be other devices with magnetic components in the terminal device, such as a lifting motor that provides power for the lifting lens, which also has a magnetic component.

As shown in Figures 6-10, in an embodiment provided in the present application, the first magnetic attraction module 40 also includes a fifth magnetic component 45, which is arranged on the side of the first body 10 away from the hinge assembly 30, and the fifth magnetic component 45 is located at a corner on the first body 10 away from the first magnetic component 41.

In this embodiment, the fifth magnetic component 45 added to the side of the first body 10 can make the entire terminal device tightly attracted when in the folded state, and the magnetic attraction force generated by multiple magnetic components can be evenly distributed on the side of the first body 10 when attracted, so that the user can feel better when opening and closing the terminal device, avoiding the situation where the hand feeling is strong in some parts and weak in other parts, thereby improving the user experience.

In an embodiment provided in the present application, the distance between the first magnetic component 41 and the second magnetic component 42 is greater than the distance between the fourth magnetic component 44 and the fifth magnetic component 45 .

In this embodiment, since the length of the first side wall 112 is limited, when the third magnetic component 43 to the fifth magnetic component 45 are arranged, the distance between the first magnetic component 41 and the second magnetic component 42 is designed to be slightly larger as much as possible, so that the magnetic field strength in the area between the first magnetic component 41 and the second magnetic component 42 is relatively low, which is conducive to debugging a specific area with low magnetic field strength or zero magnetic field strength, thereby facilitating the layout of the magnetic sensitive device 50 and facilitating structural optimization.

Optionally, a fifth magnetic component 45 may be added when the first magnetic attraction module 40 only includes the first magnetic component 41 and the second magnetic component 42 , for example, as shown in FIGS. 2 to 5 .

Correspondingly, the distance between the first magnetic component 41 and the second magnetic component 42 is greater than the distance between the second magnetic component 42 and the fifth magnetic component 45. This has the advantage of being conducive to debugging specific areas of low magnetic field strength or zero magnetic field strength, thereby facilitating the layout of the magnetic sensitive device 50 and facilitating structural optimization.

Finally, it should be noted that the above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
