[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figure 1-3 As shown, the utility model provides a screen door safety voice prompt device, including a waterproof shell, wherein a voltage conversion module 2, a voice playback module 3, and a speaker 4 are provided in the waterproof shell. The voltage conversion module 2 is connected to the voice playback module 3, and the voice playback module 3 is connected to the speaker 4. The voltage conversion module 2 is used to convert the terminal door opening signal into the voice playback module working voltage, and the voice playback module 3 and the speaker 4 are used to play the safety prompt audio;

[0026] The voltage conversion module 2 includes a resistor R1, a resistor R2, and a diode D1. The first end of the resistor R1 is connected to the +110V power supply, the second end is connected to the first end of the resistor R2, the second end of the resistor R2 is connected to the anode of the diode D1, and the cathode of the diode D1 is grounded.

[0027] The voice playing module 3 includes a voice playing chip, a USB interface, a FLASH interface, and a speaker interface. The voice playing chip is also connected to an audio power amplifier chip.

[0028] In this utility model, the voltage conversion module "power supply" outputs 3.3V, connected Figure 3 The 3.3V is used to power the voice module.

[0029] The utility model provides a waterproof terminal 1 on the shell of the waterproof housing. The waterproof terminal 1 is clamped on the shell and is responsible for blocking the gap between the wire and the shell.

[0030] The voltage conversion module of the present invention uses R1 and R2 to divide 110V into a 5V power supply. The voltage at point A to ground is 110V*R14 / (R13+R14)=about 5V, and the existing terminal door opening signal (110VDC signal) is converted into the working voltage of the voice module (5VDC). When the terminal door is opened, the voltage conversion module works, and when the terminal door is closed and locked, the voltage conversion module loses power.

[0031] This utility model's voice playback module utilizes the JR6001 voice playback chip, with interfaces including a USB port, a FLASH port, and a speaker port. The FLASH chip utilizes a W25Q32 chip. The module powers up upon receiving a 5V power supply and is set to play sequentially in a list format. Since its memory stores only one safety reminder audio, it plays the safety reminder audio once upon powering up. When the terminal door is closed, the 5V signal to the voice playback module is turned off, de-energizing the entire module and consuming no power.

[0032] When the utility model is working, the voice prompt device is installed in the decorative panel above the end door; in order to realize the function, the voice prompt device is connected in parallel to the signal line of the end door signal light. When the end door is opened, the signal light is lit, and at the same time, a 110V DC voltage is provided to the voice prompt device to start the voice prompt function. When the end door is closed, the voice prompt is stopped.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
