When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0052] Figure 1 is a schematic diagram of a terminal device according to an exemplary embodiment Figure 1 .like Figure 1 As shown, the terminal device at least includes:

[0053] Mainboard 101, battery 102 and geomagnetic field detection module 103;

[0054] The geomagnetic field detection module 103 and the main board 101 are connected to form a first loop;

[0055] The battery 102 and the mainboard 101 are connected to form a second circuit;

[0056] The first loop and the second loop are separately arranged.

[0057] The above-mentioned terminal device may be a mobile terminal and a wearable electronic device. The mobile terminal includes a mobile phone, a notebook and a tablet computer, and the wearable electronic device includes a smart watch, which is not limited in the embodiments of the present disclosure.

[0058] The above-mentioned mainboard is used to support various functional modules on the terminal device and can realize electrical connection and electrical insulation between the functional modules. The mainboard includes but is not limited to the printed circuit board (PCB) of the terminal device.

[0059] The above-mentioned battery is used to provide electrical signals to various functional modules in the terminal device.

[0060] The geomagnetic field detection module is used to detect geomagnetic field information, which can determine the orientation of the terminal device and can also assist the navigation function of the terminal device to realize the positioning of the terminal device. The geomagnetic field information includes the intensity of the geomagnetic field and the direction of the geomagnetic field. It should be noted that the geomagnetic field detection module may include a detection circuit, which detects the geomagnetic field information under the drive of the detection circuit. The detection circuit includes but is not limited to an integrated circuit or a discrete circuit.

[0061] In the disclosed embodiment, the magnetic field detection module may be located on the mainboard, or may be located in a space outside the mainboard in the terminal device. When the magnetic field detection module is located on the mainboard, the first loop formed by the connection between the magnetic field detection module and the mainboard may be directly routed in the mainboard to form the first loop; when the magnetic field detection module is located in a space outside the mainboard in the terminal device, the magnetic field detection module may form the first loop with the mainboard through a flexible circuit board.

[0062] It should be noted that the above-mentioned first circuit can be used to transmit the geomagnetic field information detected by the geomagnetic field detection module to the mainboard, and can also be used to provide an electrical signal to the geomagnetic field detection module, which is not limited in the embodiments of the present disclosure.

[0063] In the disclosed embodiment, the second circuit formed by the connection between the battery and the mainboard can be used to provide electrical signals to various functional devices on the mainboard, and can also be used for the control module on the mainboard to output control signals to the battery to achieve battery management.

[0064] It should be noted that the terminal device may further include: a battery interface, which is located on the main board. The battery can be connected to the main board by connecting to the battery interface, thereby forming a second circuit.

[0065] In the embodiment of the present disclosure, the first loop and the second loop are separately arranged, which may include: the first loop and the second loop are separated at the wiring position. The separation of the first loop and the second loop at the wiring position includes: the first loop is arranged in an area outside the main board, and may no longer be arranged on the main board, thereby achieving the separation of the first loop and the second loop at the wiring position.

[0066] The first loop and the second loop are separated and arranged, and may also include: the first loop and the second loop are separated in physical distance. The separation of the first loop and the second loop in physical distance includes: the distance between the first loop and the second loop is greater than a first distance threshold. The first distance threshold can be set according to actual circuit design requirements. For example, the first distance threshold can be set in the range of 3 cm to 8 cm.

[0067] Through the embodiment of the present disclosure, the first circuit formed by the geomagnetic field detection module and the second circuit formed by the battery are separated and arranged, so that the first circuit can be kept away from the return current generated when the battery charges the various functional modules on the mainboard, thereby reducing the influence of the magnetic field generated by the return current in the terminal device on the geomagnetic field detection module, and improving the detection accuracy of the geomagnetic field detection module.

[0068] In some embodiments, Figure 2 As shown, the terminal device also includes:

[0069] A frame 104 is provided separately from the second loop;

[0070] The geomagnetic field detection module 103 is installed on the frame 104 and is used to detect geomagnetic field information.

[0071] That is to say, installing the geomagnetic field detection module on the frame can separate the geomagnetic field detection module from the second circuit, thereby making the first circuit away from the magnetic field generated when the battery charges the functional modules on the mainboard, thereby reducing the influence of the magnetic field generated by the return current in the terminal device on the geomagnetic field detection module and improving the detection accuracy of the geomagnetic field detection module.

[0072] In the disclosed embodiment, in order to better separate the geomagnetic field detection module from the second circuit in terms of physical distance, when setting the position of the geomagnetic field detection module on the frame, the distance between the geomagnetic field detection module on the frame and the battery can be set to be greater than the second distance threshold. The second distance threshold can be set according to actual circuit design needs. For example, the second distance threshold can be set in the range of 2 cm to 6 cm.

[0073] In some embodiments, Figure 3 As shown, the terminal device also includes:

[0074] A button module 105 is installed on the frame 104;

[0075] The magnetic field detection module 103 is disposed adjacent to the button module 105 .

[0076] The above-mentioned key module includes: a power key for turning on or off the terminal device, or a volume adjustment key for increasing or decreasing the output volume of the audio signal. It should be noted that the key module includes one or both of the power key and the volume adjustment key, which is not limited in the embodiment of the disclosure.

[0077] In the disclosed embodiment, the magnetic field detection module and the key module are arranged adjacent to each other, including: the magnetic field detection module and the key module are located on the same side of the frame. For example, when the terminal device is a mobile phone and the key module is located at the top of the mobile phone, the magnetic field detection module can be arranged to be located at the top of the mobile phone; when the terminal device is a mobile phone and the key module is located at the side of the mobile phone, the magnetic field detection module can be arranged to be located at the side of the mobile phone.

[0078] It should be noted that the motherboard includes multiple signal layers and ground layers. Each signal layer is provided with a power line connected to the battery, and the ground layer surrounds the edge of the motherboard. The ground layer is connected to the ground wires of various circuits on the motherboard to provide a common reference point for the potential of the various circuits; the signal layer is used to arrange the wires for transmitting signals.

[0079] When the battery is in working state, the power line supplies power to each functional module in the terminal device connected to the power supply, and then an electrical loop is formed on the mainboard. In the electrical loop, the current will flow to a low-impedance position and eventually flow to the ground layer. Moreover, the impedance of the electrical loop away from the button module position is lower than the impedance of the position close to the button module position. Therefore, the current in the electrical loop will not flow to a position close to the button module. Based on this, the magnetic field detection module is arranged adjacent to the button module, so that the magnetic field detection module can be kept away from the magnetic field generated by the return current in the electrical loop, thereby reducing the influence of the magnetic field generated inside the terminal device on the geomagnetic field detection module, thereby improving the detection accuracy of the geomagnetic field detection module.

[0080] In some embodiments, Figure 4 As shown, the main board 101 includes a control module and a connection interface 101a for communicating with the control module;

[0081] The geomagnetic field detection module 103 and the main board 101 are connected to the connection interface 101a via a flexible circuit board 106 to form the first loop;

[0082] The first loop is used to transmit the geomagnetic field information detected by the geomagnetic field detection module 103 to the control module.

[0083] In the disclosed embodiment, the geomagnetic field detection module is connected to the connection interface through a flexible circuit board, and then connected to the control module through the connection interface, thereby realizing communication between the geomagnetic field detection module and the control module. It should be noted that the connection interface can be set on the area of ​​the mainboard close to the geomagnetic field detection module. In this way, the flexible circuit board connecting the geomagnetic field detection module and the connection interface does not need to be set across regions, the design length of the flexible circuit board can be reduced, and the layout of each device in the terminal device is more reasonable.

[0084] In some embodiments, Figure 5As shown, the connection interface 101a includes: a first type of terminal and a second type of terminal arranged in parallel with the first type of terminal;

[0085] The flexible circuit board includes: a first type transmission line 106a and a second type transmission line 106b arranged in parallel with the first type transmission line 106a;

[0086] The geomagnetic field detection module 103 is connected to the first type of terminal through the first type of transmission line 106a of the flexible circuit board;

[0087] The button module 105 is connected to the second-type terminal through the second-type transmission line 106b of the flexible circuit board.

[0088] That is to say, the key module and the geomagnetic field detection module in the embodiment of the present disclosure can be connected to the control module on the mainboard through the same flexible circuit board. In this way, compared with setting two flexible circuit boards for the key module and the geomagnetic field detection module, the key module and the geomagnetic field detection module in the embodiment of the present disclosure share one flexible circuit board, which can reduce the number of flexible circuit boards and reduce the design cost of the terminal device on the one hand; on the other hand, compared with setting two flexible circuit boards, setting one flexible circuit board can reduce the space occupied inside the terminal device and improve the space utilization rate of the terminal device.

[0089] The first type of transmission line can be used to transmit electrical signals to the geomagnetic field detection module, and can also be used to transmit the geomagnetic field information detected by the geomagnetic field detection module to the control module. Figure 6 As shown, the first type of transmission line includes a power line 106a1, a ground line 106a2 and two signal lines 106a3, and a filter capacitor 107 is provided on the power line 106a1. The filter capacitor is used to reduce the influence of power signal fluctuation on the geomagnetic field detection module.

[0090] The second type of transmission line can be used to transmit electrical signals to the key module, and can also be used to transmit key information obtained by the key module to the control module. The second type of transmission line can also include: power lines, ground lines, and communication signal lines corresponding to key information, which are not limited in the embodiments of the present disclosure.

[0091] The first type of terminals and the second type of terminals are both conductive terminals, which are formed of metal or alloy materials.

[0092] In some embodiments, the flexible circuit board includes:

[0093] A first connecting portion, located at a first end of the flexible circuit board, comprising connecting terminals connected to the first type of terminals and the second type of terminals respectively;

[0094] A second connecting portion, located at a second end of the flexible circuit board, comprising a plurality of one or more connecting terminals connected to the geomagnetic field detection module; the second end is an opposite end of the first end;

[0095] The third connecting portion is located at the second end of the flexible circuit board and is separated from the second connecting portion, and includes one or more connecting terminals connected to the key module.

[0096] That is to say, the geomagnetic field detection module can be connected to the first type of terminal of the connection interface through the second connection part of the flexible circuit board, the first type of transmission line, and the connection terminal on the first connection part connected to the first type of terminal. The key module can be connected to the second type of terminal of the connection interface through the third connection part of the flexible circuit board, the second type of transmission line, and the connection terminal on the first connection part connected to the second type of terminal. In this way, the geomagnetic field detection module and the key module can be connected to the connection interface respectively through a flexible circuit board, and then the control module can communicate with the geomagnetic field detection module and the key module respectively.

[0097] In the disclosed embodiment, the second connection part is used to connect the geomagnetic field detection module, and the third connection part is used to connect the key module. The geomagnetic field detection module and the key module are arranged adjacent to each other, so the second connection part and the third connection part are arranged separately, so that the second connection part can be better connected to the geomagnetic field detection module, and the third connection part can be better connected to the key module, thereby making the internal device layout of the terminal device more reasonable.

[0098] In some embodiments, the frame has a groove protruding toward the outside of the terminal device;

[0099] The geomagnetic field detection module is located in the groove.

[0100] In the disclosed embodiment, the geomagnetic field detection module is disposed in the groove of the frame, so that the geomagnetic field detection module does not need to occupy additional space inside the terminal device, thereby improving the space utilization rate of the terminal device.

[0101] It should be noted that the volume of the groove can be set according to the volume of the space occupied by the geomagnetic field detection module. For example, the volume of the groove can be set to be equal to or greater than the volume of the space occupied by the geomagnetic field detection module. In this way, the geomagnetic field detection module can be placed in the groove.

[0102] Of course, the shape of the groove can also be set according to the shape of the geomagnetic field detection module. For example, the shape of the groove can be set to be similar to or the same as the shape of the geomagnetic field detection module. In this way, when designing the volume of the groove, the geomagnetic field detection module can be placed according to the shape of the geomagnetic field, which can reduce the situation where more space is needed to place the geomagnetic field detection module due to shape mismatch, and thus can reduce the space required for the groove to place the geomagnetic field detection module.

[0103] In some embodiments, the geomagnetic field detection module has a packaging surface;

[0104] The terminal device further includes:

[0105] The first buffer is located between the frame and the packaging surface and is used to protect the packaging surface.

[0106] The above-mentioned packaging surface may be formed of glass material. It should be noted that the packaging surface formed of glass material can penetrate the geomagnetic field, so that the geomagnetic field detection module can better detect the geomagnetic field information and improve the detection accuracy of the geomagnetic field detection module.

[0107] The first buffer is a mechanical buffer that can reduce the effect of external force on the packaging surface, thereby protecting the packaging surface. The first buffer includes but is not limited to a buffer formed of foam or a material that does not shield magnetic properties. The material that does not shield magnetic properties includes plastic or fiber.

[0108] In the embodiment of the present disclosure, the first buffer component is arranged between the frame and the packaging surface, which can effectively protect the packaging surface and reduce damage to the packaging surface during the production and assembly process.

[0109] In some embodiments, Figure 7 As shown, the terminal device also includes:

[0110] The module housing 108 and the frame 104 together form a receiving space;

[0111] The geomagnetic field detection module 103 is located in the accommodating space.

[0112] In the disclosed embodiment, the module housing may be a mechanical buffer housing, which can reduce the effect of external forces on the geomagnetic field detection module.

[0113] It should be noted that the geomagnetic field detection module can be arranged in a groove of the frame, or directly arranged on the frame. Figure 7 As shown, the terminal device further includes: an adhesive module 109, located between the magnetic field detection module 103 and the frame 104, for attaching the geomagnetic field detection module to the frame. The adhesive module includes but is not limited to colloid.

[0114] In the disclosed embodiment, the module housing is provided with connection holes, which are respectively connected to the flexible circuit board and the geomagnetic field detection module to establish an electrical connection between the geomagnetic field detection module and the flexible circuit board.

[0115] In some embodiments, Figure 7 As shown, the geomagnetic field detection module 103 has a packaging surface 110;

[0116] The terminal device further includes:

[0117] The second buffer member 111 is located between the module housing 108 and the packaging surface 110 , and is used to protect the packaging surface 110 .

[0118] The second buffer is a mechanical buffer that can reduce the effect of external force on the packaging surface, thereby protecting the packaging surface. The second buffer includes but is not limited to a buffer formed of foam or a material that does not shield magnetism. The material that does not shield magnetism includes plastic or fiber.

[0119] In the disclosed embodiment, the second buffer component is disposed between the module housing and the packaging surface, which can play a secondary role in protecting the packaging surface and further reduce damage to the packaging surface during the production and assembly process.

[0120] In some embodiments, the hardness of the second buffer is less than the hardness of the module housing. Thus, during the production and assembly process, the second buffer and the module housing can form an anti-collision structure with different hardnesses, thereby reducing the hard-on-hard-on collision situation, and achieving better protection of the packaging surface.

[0121] In some embodiments, a surface of the module housing facing the packaging surface protrudes toward the inner side of the terminal device.

[0122] In some embodiments, the geomagnetic field detection module is a columnar body; a group of relatively arranged surfaces of the columnar body with the largest area are placed along the longitudinal direction of the frame.

[0123] That is to say, the columnar body includes a first surface and a second surface other than the first surface, and the first surface is larger than the second surface. The first surface is attached to the inner surface of the frame, and the long side of the first surface is parallel to the long side of the frame. In this way, the layout of each functional module in the terminal device is more regular.

[0124] It should be noted that the “first”, “second” and “third” in the embodiments of the present disclosure are only for the convenience of description and distinction and have no other specific meanings.
