As shown in fig. 3, in an embodiment of the present invention, a terminal is provided, including:

and the compass sensor integrated circuit chip 310 is used for detecting the magnetic field intensity of the position where the terminal is located.

In the present embodiment, the type of the compass sensor integrated circuit chip is not limited, and may be an electronic compass in general.

And the control chip 320 is used for determining the direction information of the position of the terminal according to the magnetic field intensity detected by the compass sensor integrated circuit chip. When a user needs to use the compass function on the terminal, the control chip determines the current direction information according to the signal of the compass sensor integrated circuit chip and displays the current direction information to the user through the display screen of the terminal.

In the present embodiment, the type of the control chip is not limited, and in general, it may be a CPU (terminal processor) within the terminal.

The driving device 330 controls the compass sensor integrated circuit chip to move.

In the present embodiment, the type of the driving means is not limited, and may be, for example, a motor; in this embodiment, the connection mode between the driving device and the compass sensor ic chip is not limited, for example, the driving device may be a motor, which controls the movement of a preset drawer structure, and the compass sensor ic chip is disposed on the structure.

According to the technical scheme of the embodiment, when a user needs to use the compass function of the terminal, the driving device controls the compass sensor integrated circuit chip to move from the region with larger magnetic field influence of the internal devices of the terminal to the region with smaller magnetic field influence of the internal devices of the terminal, so that the magnetic field interference of the compass sensor integrated circuit chip with the internal devices of the terminal can be reduced, and the direction information can be more accurately judged according to the detected geomagnetic field.

Compared with the foregoing embodiment, the terminal of the present embodiment includes:

And the control chip 320 is used for determining the direction information of the position of the terminal according to the magnetic field intensity detected by the compass sensor integrated circuit chip.

When the control chip needs to determine the direction information of the position of the terminal, the driving device controls the compass sensor integrated circuit chip to move from the first area to the second area, wherein the number of the hard magnetic devices in the first area is larger than that in the second area.

In this embodiment, the sizes of the first area and the second area are not limited, and since the number of the hard magnetic devices in the first area is greater than that of the hard magnetic devices in the second area, after the compass sensor integrated circuit chip moves from the first area to the second area, the interference on the compass sensor integrated circuit chip is less, which is beneficial for the compass sensor integrated circuit chip to more accurately judge the direction information.

Specifically, the first area and the second area may be set in the following manner: (1) the first region and the second region are both located within a housing of the terminal. (2) The first region is located within a housing of the terminal and the second region is located outside the housing.

In the mode (1), the first area and the second area are located in the terminal together, the layout can be carried out according to the actual free space in the terminal, and the compass sensor integrated circuit chip cannot move to the outside of the terminal because the first area and the second area are located in the terminal shell, so that the compass sensor integrated circuit chip is protected better; in the mode (2), after the compass sensor integrated circuit chip is moved to the outside of the terminal, the compass sensor integrated circuit chip can effectively avoid the magnetic field interference of the internal devices of the terminal. It is advantageous to detect the position information more accurately. As shown in fig. 4, the shaded portion represents the strength of the magnetic field environment, since the compass is found to be closer to the charging circuit when the layout is implemented, and the periphery has hard magnetic devices: the motor, the camera, the attraction magnet and the like can cause the problems that the compass detection data is inaccurate during charging, normal detection of the compass cannot be realized, and the like are uncertain.

When the mode (2) is adopted, the compass sensor integrated circuit chip extends out of the shell of the terminal from the universal serial bus interface on the terminal. The integrated circuit chip of the compass sensor is arranged on the signal connecting piece of the universal serial bus interface.

In this embodiment, the compass sensor integrated circuit chip is extended out of the housing of the terminal through a USB (universal serial bus) interface, so that multiplexing of the terminal interface is realized, and the housing of the terminal is prevented from being opened again, thereby protecting the integrity of the housing of the terminal. In this embodiment, the signal connection piece in the USB interface is utilized, so that not only the multiplexing of the signal connection piece is realized, but also the compass sensor can be smoothly extended out of the terminal.

The signal of the integrated circuit chip of the compass sensor is transmitted to the control chip through the flexible circuit board.

Specifically, the control chip acquires the current geographic position, and determines the direction information of the position of the terminal according to the magnetic field intensity detected by the compass sensor integrated circuit chip when the geographic position meets the preset condition.

In this embodiment, the directions are not necessarily determined after the integrated circuit chip of the compass sensor is controlled to move in all places, the magnetic field environments of different geographic positions are different, the directions can be accurately determined even if some places are interfered by the magnetic fields of various devices in the terminal, and the directions are difficult to accurately position if some places are interfered by the magnetic fields of the devices.

In this embodiment, two ways for the control chip to obtain the geographic location are provided:

(1) and the control chip acquires the geographic position from the satellite through the positioning device.

In this embodiment, the positioning device is typically a global positioning system chip or the like, and can directly obtain the geographical location information from the satellite.

(2) And the control chip accesses the network through the network device and acquires the geographic position from the network.

In this embodiment, the network device is used for accessing a network, such as a mobile network, and after the control chip accesses the mobile network, the current geographic location may be determined by using a base station location method.

In a specific mode of the present embodiment, a bendable FPC (flexible circuit board) and a motor drive device are used; when the compass is not used, the compass sensor IC (integrated circuit) retracts into the airtight shell of the mobile phone; when the compass is detected to be used, the CPU sends an instruction to the motor to inform the motor that the compass sensor IC is pushed out of an electromagnetic field environment, the direction of the geomagnetic field is detected at a position which is not influenced by the environment, correct compass data output is judged, and the compass data is retracted into the shell of the mobile phone after the test is finished. It can be seen that according to the technical scheme of the embodiment, the bendable FPC and the motor driving device are used, so that the self-adaptive work switching of the compass is realized, a reliable compass solution is realized for the terminal (including a smart phone and the like), the reliability and the stability of the product are improved, the influence on project progress is reduced, and the flexibility of the product is further improved for stacking.

The technical scheme of the embodiment has the advantages that: 1. the method is applied to a complex geomagnetic environment, and the stacking flexibility is improved; 2. the times of modifying the PCB are reduced, and the project progress is effectively promoted; 3. the accuracy of the compass data is improved. In summary, for personal consumer electronics products such as mobile terminals (including smart terminals, etc.), the technical solution of the embodiment further enables the personal consumer electronics products to have these features.
