Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention.

In the present embodiment, the mobile terminal 10 may include a processor 11 and two distance sensors 12. The processor 11 is electrically connected to two distance sensors 12.

In the embodiment of the present invention, the mobile terminal 10 may be a smart phone, a palmtop computer, a wearable smart device, or a tablet computer. The present invention does not limit the type of the mobile terminal 10.

The two distance sensors 12 are respectively used to detect the distance between the two positions staggered on the plane of the mobile terminal 10 and the surrounding objects. Alternatively, the two distance sensors 12 may detect the parameters or the detection performance may be the same.

The plane in which the mobile terminal 10 is located may refer to the rear case surface of the mobile terminal 10, and may also refer to the front case surface of the mobile terminal 10. The front side refers to the side of the screen of the mobile terminal 10.

Alternatively, two distance sensors 12 may be respectively disposed at two diagonal corners of the mobile terminal 10. The distance sensor 12 is disposed at a corner means that the distance between the distance sensor 12 and the side of the mobile terminal 10 closest thereto may be 0 mm to 10 mm. For example, the distance between the distance sensor 12 and the side of the mobile terminal 10 closest thereto may be 0 mm. , 5mm or 10mm. It should be understood that when the distance sensor 12 includes the actual detecting component and the corresponding detecting circuit 122, for example, when the detecting component is the sensing antenna 121, the detecting component and the detecting circuit 122 can be separately disposed, but only the actual detecting component is disposed at the corresponding position. Perform distance detection with surrounding objects.

Alternatively, the distance from the surrounding object may refer to the distance from the surface of the surrounding object. The surface of the surrounding object may be a flat surface. In this embodiment, the surface of the surrounding object may be a surface parallel to the horizontal plane, such as a table top. In other embodiments, the surrounding objects may be inclined or vertical, such as the surface of a cell phone holder.

The corresponding position may be two positions staggered on the plane of the mobile terminal 10 described above. For example, as shown in FIG. 1, the corresponding position detected by the distance sensor 12 in the upper left corner refers to the upper left corner, for example, the upper left corner of the rear housing surface of the mobile terminal 10; for example, the corresponding position detected by the distance sensor 12 in the lower right corner. It means at the lower right corner, for example, at the lower right corner of the surface of the rear casing of the mobile terminal 10.

In this embodiment, the processor 11 is configured to control the mobile terminal 10 to enter the first time when each of the two distance sensors 12 detects that the distance between the corresponding position and the surrounding object is less than or equal to the preset distance value. status. For example, as shown in FIG. 1, the distance sensor 12 located at the upper left corner of the mobile terminal 10 detects that the distance from the surrounding object at the upper left corner is less than or equal to the preset distance value, and the distance sensor 12 located at the lower right corner of the mobile terminal 10 also detects When the distance from the surrounding object in the lower right corner is less than or equal to the preset distance value, it indicates that the mobile terminal 10 is flat on the surface of the surrounding object, and the processor 11 controls the mobile terminal 10 to enter the first state.

In this embodiment, the processor 11 is further configured to control the mobile terminal 10 to enter the second state when any one of the two distance sensors 12 detects that the distance between the corresponding position and the surrounding object is greater than the preset distance value. For example, as shown in FIG. 1 , if one of the distance sensor 12 located at the upper left corner and the distance sensor 12 located at the lower right corner detects that the distance between the corresponding position and the surrounding object is greater than the preset distance value, it indicates that the mobile terminal 10 is not laid flat. At the surface of the surrounding object, the processor 11 controls the mobile terminal 10 to enter the second state.

Optionally, the first state may be a screen lock state of the mobile terminal 10, and the second state may be a screen unlock state of the mobile terminal 10. In other embodiments, the first state may be a state in which the screen brightness is a first brightness value, and the corresponding second state may be a state in which the screen brightness is a second brightness value, wherein the first brightness value is smaller than the second brightness value. In other embodiments, the first state may be a low performance low power state, and the corresponding second state may be a relatively high performance high power consumption state. In the low performance and low power consumption state, the screen brightness is relatively low, the mobile data function is turned off, the WIFI function is turned off, and the positioning function is turned off; in the high performance and high power consumption state, the screen brightness is relatively high, the mobile data can be turned on, and the WIFI function is enabled. It can be turned on and the positioning function can be turned on.

Optionally, the preset distance value may be a preset distance value. For example, the mobile terminal 10 receives a setting instruction of the user, acquires a preset distance value according to a setting instruction of the user, and stores the obtained preset distance value to In the memory connected to the processor 11. When the processor 11 needs to determine the magnitude relationship between the distance between the corresponding location and the surrounding object and the preset distance value, the preset distance value is read from the memory and the distances of the acquired distance sensors 12 from the surrounding objects are respectively preset. Distance value comparison.

Optionally, the preset distance value may be set according to a plurality of distance values that are detected multiple times when the mobile terminal 10 is placed on the surrounding object, for example, when placed on the same surrounding object, the multiple times are taken and placed peacefully. On the surrounding object, the reciprocating operation is to set the maximum value of the plurality of distance values detected by the sensor 12 multiple times as the preset distance value when lying on the surrounding object multiple times. Alternatively, for different surrounding objects, the maximum values corresponding to different surrounding objects are acquired in the above manner, and the average value of the maximum values corresponding to different surrounding objects is obtained as the preset distance value.

In another embodiment, the processor 11 is configured to detect, at each of the two distance sensors 12, that the distance of the corresponding position from the surrounding object is less than or equal to the preset distance value, and the processor 11 determines that the movement is When the running application of the terminal 10 does not include the preset application, the mobile terminal 10 is controlled to enter the first state. Optionally, the preset application may be a video playing program, a game program, or a document program. The present invention is not limited thereto, and the user may perform preset according to requirements.

For example, if the user is holding the mobile terminal 10 to watch the video, the video playing program is running. If the mobile terminal 10 is placed on the table during the video viewing process, each distance sensor 12 can detect that the distance between the corresponding location and the desktop is less than or Equal to the preset distance value, but at this time, the processor 11 does not control the mobile terminal 10 to enter the first state; if the processor 11 detects that the application that the mobile terminal 10 is running is not the preset program, the processor 11 controls the mobile terminal. 10 enters the first state. In this way, it is possible to avoid affecting the user's use of the preset application.

Optionally, in another embodiment, the processor 11 is configured to indicate that each distance sensor 12 of the two distance sensors 12 detects that the distance of the corresponding position from the surrounding object is less than or equal to the preset distance value. The terminal 10 is placed flat on the surrounding object, and controls the mobile terminal 10 to enter the first when the processor 11 detects that the mobile terminal 10 does not receive the user operation instruction within a preset time period from when the mobile terminal 10 is placed on the surrounding object. status.

For example, the user is using the mobile terminal 10 to perform a chat, and the mobile terminal 10 is placed on the table during the chat, although each distance sensor 12 can detect that the distance between the corresponding location and the surrounding object is less than or equal to the preset distance value, but If the processor 11 detects that the mobile terminal 10 has received the operation instruction of the user within the preset time period, the processor 11 does not control the mobile terminal 10 to enter the first state; if the processor 11 detects the preset at this time When the mobile terminal 10 does not receive the operation instruction of the user within the time limit, the mobile terminal 10 is controlled to enter the first state.

Optionally, each of the distance sensors 12 may include a detection circuit 122 and a sensing antenna 121, and the sensing antenna 121 is connected to the processor 11 through a detection circuit 122 corresponding thereto.

It can be understood that, in this embodiment, the sensing antenna 121 can be disposed at the corresponding position described above. For example, the sensing antenna 121 can be disposed at a corner of the back surface of the housing of the mobile terminal 10 and fixed on the inner surface of the rear housing. . Wherein, the inner surface fixed to the back casing may be attached to the inner surface of the casing. The detection circuit 122 can be disposed on a circuit board of the mobile terminal 10.

The sensing antenna 121 can be used to induce a corresponding amount of charge according to the distance of the sensing antenna 121 from surrounding objects.

The surrounding object and the sensing antenna 121 can be regarded as one capacitor. The surrounding object and the sensing antenna 121 can be regarded as two plates of the capacitor, respectively. Since the charge on the plate of the capacitor is inversely proportional to the distance between the two plates, the distance between the sensing antenna 121 and the surrounding object decreases. The amount of charge on the sensing antenna 121 becomes larger; as the distance between the sensing antenna 121 and the surrounding object increases, the amount of charge on the sensing antenna 121 decreases, and the amount of charge on the sensing antenna 121 and the distance of the sensing antenna 121 from the surrounding object are One correspondence and inversely proportional to each other. The sensing antenna 121 can induce a corresponding amount of charge according to the distance between the sensing antenna 121 and surrounding objects.

The detecting circuit 122 is configured to generate a corresponding voltage value, current value or level value according to the amount of charge induced on the sensing antenna 121, and the processor 11 is configured to control the mobile terminal to enter the first state according to the voltage value, the current value or the level value. Or the second state. Among them, the level value, voltage value or current value can represent the distance between the distance sensor and the surrounding object.

It can be understood that when the detecting circuit 122 is used to generate a corresponding voltage value or current value according to the above-mentioned amount of charge, the voltage value or current value can be used to represent the distance value of the distance sensor 12 and surrounding objects, and the distance sensor 12 is The distance from the surrounding object is compared with the preset distance value, so that when each of the two distance sensors 12 detects that the distance between the corresponding position and the surrounding object is less than or equal to the preset distance value, the control moves The terminal 10 enters the first state, and when any one of the two distance sensors 12 detects that the distance between the corresponding position and the surrounding object is greater than the preset distance value, the mobile terminal 10 is controlled to enter the second state; when the detecting circuit 122 is used When the corresponding level value is generated according to the amount of charge described above, the level value is used to indicate whether the distance value of the distance sensor 12 and the surrounding object is greater than a preset distance value, thereby controlling the mobile terminal 10 to enter the first state or the second state.

Of course, in the present invention, the detection circuit 122 can also generate a corresponding power value or impedance value according to the amount of charge, which is not limited by the present invention.
