[0005] Furthermore, in the width direction of the electronic device, the Hall element is located on one side of the body, and the processor is located on the other side of the body.
[0006] Furthermore, the first Hall element and the second Hall element are spaced apart along the length of the electronic device.
[0007] Furthermore, the first Hall element and the second Hall element are disposed close to each other in the middle of the electronic device.
[0008] Furthermore, the number of the first Hall element is set to be multiple, and the number of the second Hall element is set to be multiple; in the length direction of the electronic device, the first Hall element and the second Hall element are alternately arranged.

Detailed Implementation
[0025] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0026] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0027] like Figure 1 As shown, this application provides an electronic device assembly, including a functional component 60 and an electronic device. The electronic device includes a main body 10 and a processor 20, an execution component 30, and a Hall element 40 installed within the main body 10.
[0028] The Hall element 40 includes a first Hall element 41 and a second Hall element 42. The detection polarities of the first Hall element 41 and the second Hall element 42 are opposite. For example, the first Hall element 41 can be turned on when a North pole magnetic field is detected, and the second Hall element 42 can be turned on when a South pole magnetic field is detected.
[0029] The first Hall element 41 and the second Hall element 42 are electrically connected to the input terminal 21 of the processor 20, and the execution component 30 is electrically connected to the output terminal 22 of the processor 20. The execution component 30 is a component within an electronic device, such as a screen or vibration motor. The functional component 60 may be a protective cover, etc.
[0030] When both the first Hall element 41 and the second Hall element 42 are in the open state, the actuator 30 controls the electronic device to operate in a first state. When at least one of the first Hall element 41 and the second Hall element 42 is in the closed state, the actuator 30 controls the electronic device to operate in a second state.
[0031] The functional component 60 is provided with a first magnetic pole portion 61 and a second magnetic pole portion 62 with opposite polarities. When the actuating component 30 is in a first working state, the first magnetic pole portion 61 is aligned with the first Hall element 41, and the second magnetic pole portion 62 is aligned with the second Hall element 42.
[0032] By setting a first Hall element 41 and a second Hall element 42 with opposite detection polarities, and only when both Hall elements 40 are sensed and turned on, the actuator 30 controls the electronic device to switch from the second operating state to the first operating state. Since external magnetic field interference is usually unipolar, at most only one of the first Hall element 41 and the second Hall element 42 will be turned on by magnetic field interference, thus improving the anti-interference effect of the electronic device.
[0033] Taking an electronic device with the screen as the execution component 30 and the protective case as the functional component 60 as an example, the first operating state of the electronic device is the screen-off state, and the second operating state is the screen-on state. When the protective case is closed, the first magnetic pole portion 61 is aligned with the first Hall element 41, causing the first Hall element 41 to open. The second magnetic pole portion 62 is aligned with the second Hall element 42, causing the second Hall element 42 to open. With the first Hall element 41 and the second Hall element 42 open, the screen is in the screen-off state. When the protective case is opened, the first Hall element 41 and the second Hall element 42 are closed, causing the screen to open.
[0034] In other embodiments, the functional component 60 may also be a keyboard. In the first operating state, the electronic device is in keyboard input mode, where text input via tapping the screen is disabled. In the second operating state, the electronic device is in normal screen input mode, where the user inputs text by tapping the virtual keyboard on the screen.
[0035] In other embodiments, the functional component 60 may also be an AR mirror. In the first operating state, the electronic device is located at the operating interface of the AR software. In the second operating state, the electronic device is located at the operating interface of a non-AR software. When the AR mirror is installed on the electronic device, the electronic device can switch from the non-AR software operating interface to the AR software operating interface.
[0036] When subjected to external magnetic interference, taking the example of the first Hall element 41 turning on when subjected to a N-pole magnetic field and the second Hall element 42 turning on when subjected to a S-pole magnetic field, when the magnetic field interference is from the N-pole, only the first Hall element 41 turns on, while the second Hall element 42 remains closed. When the magnetic field interference is from the S-pole, only the second Hall element 42 turns on, while the first Hall element 41 remains closed.
[0037] In operation, the first Hall element 41 and the second Hall element 42 are not affected by the magnetic field and are both in the off state, with the actuator 30 in the second working state. During magnetic field interference, only one of the first Hall element 41 and the second Hall element 42 is turned on, and the actuator 30 remains in the second working state without changing its working state.
[0038] Continuing with the example of the screen (executing component 30) and the protective case (functional component 60), during the use of the electronic device, the protective case is in the open state, the Hall element is separated from the magnetic poles on the protective case, and the screen remains on. When subjected to magnetic field interference, the screen remains on and will not switch to an off state due to the interference. When the protective case is closed, the screen remains off. When subjected to magnetic field interference, the screen remains off and will not switch to an on state due to the interference.
[0039] In one embodiment, in the width direction X of the electronic device, the Hall element 40 is located on one side of the main body 10, and the processor 20 is located on the other side of the main body 10. By distributing the Hall element 40 and the processor 20 on both sides of the main body 10, the distance between the processor 20 and the Hall element 40 is increased, avoiding interference from the magnetic field that the processor 20 may generate on the Hall element 40, improving the accuracy of triggering the Hall element 40, and enhancing the user experience.
[0040] In this embodiment, the first Hall element 41 and the second Hall element 42 can be spaced apart in the length direction Y of the electronic device, which facilitates alignment with the magnetic pole portion of the functional component 60, further improving the accuracy of triggering the Hall element 40 and enhancing the user experience.
[0041] In this embodiment, the first Hall element 41 and the second Hall element 42 are arranged close to each other in the middle of the electronic device to improve the compactness of the Hall element 40 distribution and increase the space utilization of the electronic device. At the same time, even if there are multiple interfering magnetic fields of opposite polarity in the outside, the close proximity and concentration of the first Hall element 41 and the second Hall element 42 reduces the risk of simultaneous exposure to interfering magnetic fields of opposite polarity, further improving the anti-interference capability of the electronic device.
[0042] In one embodiment, such as Figure 2 As shown, the number of first Hall elements 41 and second Hall elements 42 is set to multiple. Along the length Y direction of the electronic device, the first Hall elements 41 and second Hall elements 42 are alternately arranged. The functional component 60 is provided with first magnetic pole portions 61 and second magnetic pole portions 62 in corresponding numbers and positions. By setting multiple first Hall elements 41 and multiple second Hall elements 42, the conditions for triggering the Hall elements 40 are increased, further improving the anti-interference capability of the electronic device.
[0043] Specifically, the first Hall element 41 and the second Hall element 42 can be arranged alternately in the order of one first Hall element 41 and one second Hall element 42. Alternatively, they can be arranged alternately in the order of multiple first Hall elements 41 and one second Hall element 42. The specific alternation order of the first Hall element 41 and the second Hall element 42 is not limited.
[0044] In one embodiment, such as Figure 3As shown, the electronic device also includes an AND gate circuit 50, which includes a first input terminal 51, a second input terminal 52, and an AND gate output terminal 53. A first Hall element 41 is electrically connected to the first input terminal 51, a second Hall element 42 is electrically connected to the second input terminal 52, and the AND gate output terminal 53 is electrically connected to the input terminal 21 of the processor 20.
[0045] By setting up the AND gate circuit 50, the first Hall element 41 and the second Hall element 42 can output signals through the AND gate output terminal 53, which reduces the interface occupation of the processor 20 and improves the integration of electronic devices.
[0046] like Figure 4 and Figure 5 As shown, the main body 10 includes a front side 11, a back side 12, and a side side 13. The front side 11 and the back side 12 are positioned opposite each other in the thickness direction Z of the electronic device, and the side side 13 connects the front side 11 and the back side 12. The side side 13 includes a first side side 131, a second side side 132, a third side side 133, and a fourth side side 134. The first side side 131 and the second side side 132 are positioned opposite each other in the width direction X of the electronic device. The third side side 133 and the fourth side side 134 are positioned opposite each other in the length direction Y of the electronic device.
[0047] The first Hall element 41 includes a first detection surface 411, and the second Hall element 42 includes a second detection surface 421. In one embodiment, the first detection surface 411 faces the front 11, and the second detection surface 421 faces the side 13. By detecting magnetic fields in both directions, the activation conditions of the Hall element 40 are increased, thereby improving the anti-interference capability of the electronic device.
[0048] In this embodiment, taking the functional component 60 as a protective sleeve as an example, the functional component 60 is provided with a binding strap 64. A first magnetic pole portion 61 is disposed on the functional component 60, and a second magnetic pole portion 62 is disposed on the binding strap 64. When the protective sleeve is closed, the binding strap 64 surrounds the electronic device from the side. The second magnetic pole portion 62 is aligned with the second Hall element 42.
[0049] In this embodiment, the first Hall element 41 and the second Hall element 42 are disposed close to the first side surface 131, and the second detection surface 421 is disposed facing the first side surface 131. When a user holds the electronic device, their fingers mainly operate from both sides in the width direction X of the electronic device. By placing the first Hall element 41 and the second Hall element 42 close to the first side surface 131, the anti-interference capability of the electronic device is improved, while conforming to the user's operating habits and enhancing the user experience.
[0050] In one embodiment, such as Figure 6 and Figure 7As shown, the electronic device also includes a third Hall element 43. The third Hall element 43 is electrically connected to the processor 20. The third Hall element 43 is disposed near the third side 133. The third Hall element 43 includes a third detection surface 431 disposed facing the third side 133. The first Hall element 41, the second Hall element 42, and the third Hall element 43 are oriented in three directions, increasing the conditions for the Hall element 40 to be triggered and further improving the anti-interference capability of the electronic device.
[0051] In this embodiment, the functional component 60 further includes a third magnetic pole portion 63. The specific polarity of the third magnetic pole portion 63 is not limited. Taking the functional component 60 as a protective sleeve provided with binding straps 64 as an example, the number of binding straps 64 can be multiple. Binding straps 64 are provided on the side, and on the top or bottom of the functional component 60. When the protective sleeve is closed, one binding strap 64 surrounds the electronic device from the side, and the second magnetic pole portion 62 is aligned with the second Hall element 42. The remaining binding straps 64 surround the electronic device from the top or bottom, so that the third magnetic pole portion 63 is aligned with the third Hall element 43.
[0052] The electronic device in this application may be a mobile phone, tablet computer, etc., and there is no specific limitation on the type.
[0053] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict.
