In some possible embodiments, the second preset range is a range with a vertical distance from the ground being a first preset distance, and a point with a vertical distance from the left edge and/or the right edge of the door being a second preset distance being a center of a circle, and the preset length being a radius. The first preset distance is determined according to the height of the user, the second preset distance is determined according to the diameter of the sensing range of the voice prompt apparatus 10, and the preset length is determined according to the arm length of the user.

Referring to fig. 2, for example, the voice prompt apparatus 10 is installed on the right side of the door, and an embodiment of the present application provides a schematic diagram of the second preset range. As shown in fig. 2, D is a door, C is a right wall of the door, a is a second preset range in which the voice prompt apparatus 10 is located, D1 represents a first preset distance, D2 represents a second preset distance, and O is a center of a circle.

The voice prompt apparatus 10 may include: pyroelectric detection module 11, sensing module 12, control module 13 and voice prompt module 14.

The voice prompt module 14 is connected with the control module 13 and is used for outputting voice information when receiving the first control signal; the voice information is used for prompting a user to detect all equipment of the house and prompting the user to carry the door opening assembly.

In the embodiment of the present application, when the pyroelectric detection module 11 detects that the user moves within the first preset range, the pyroelectric detection module 11 indicates that the user moves near the door, and thus the pyroelectric detection module 11 can output the first level signal. The first preset range specifically refers to a range formed by the fact that the distance between a human body and the center of a door is smaller than or equal to twice of a preset length.

The first level signal may be a high level signal or a low level signal.

In some possible embodiments, the pyroelectric detection module 11 indicates that the user is not approaching the door when the user is not detected to move within the first preset range, or the user is simply stopped and not moving at a place approaching the door, and thus the pyroelectric detection module 11 may output the fourth level signal.

When the control module 13 detects the first level signal and the second level signal, it indicates that the user needs to go out at this time and does not carry the door opening assembly, so the control module 13 can output the first control signal.

In practical applications, the control module 13 may be a controller. The control module 13 may be, for example, a micro control unit (Micro controller Unit, MCU), a microprocessor (Micro Processor Unit, MPU), or a central processing unit (Central Processing Unit/Processor, CPU), without limitation.
