[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a voice broadcast device, including a payment broadcast device body 1, a fastening frame 4 is provided on one side of the payment broadcast device body 1, the fastening frame 4 is partially embedded in the interior of the payment broadcast device body 1 to improve the tightness of the connection between the fastening frame 4 and the payment broadcast device body 1, a display board 3 is placed between the fastening frame 4 and the payment broadcast device body 1, the display board 3 fits with the inner wall of the fastening frame 4, so that after the fastening frame 4 and the payment broadcast device body 1 are connected, the display board 3 can be bound between the payment broadcast device body 1 and the fastening frame 4 to complete the installation of the display board 3, and an adhesive area 5 is provided on the surface of the display board 3 to provide an adhesive position for the payment QR code.

[0022] The main body 1 of the payment broadcasting device has speakers 2 protruding from the surface of the main body 1 on both sides for broadcasting the payment amount and other information. The main body 1 of the payment broadcasting device has T-shaped connecting grooves 6 on both sides. The fastening frame 4 is fixedly connected to both sides of the connecting rods 8. The surface of the connecting rods 8 slides against the inner wall of the connecting grooves 6. The end of the connecting rods 8 away from the fastening frame 4 is arc-shaped. The inner wall of the connecting groove 6 is slidably connected to two locking rods 7. The opposite ends of the two locking rods 7 do not contact each other, so that when the arc-shaped end of the connecting rod 8 comes into contact with the two locking rods 7, it can smoothly push the two locking rods 7 to move in opposite directions, ensuring the smooth operation of the device.

[0023] The surface of the locking rod 7 is provided with a rubber pad, which increases the friction between the locking rod 7 and the inside of the main body 1 of the payment broadcasting device, preventing the locking rod 7 from moving randomly in the main body 1 of the payment broadcasting device and ensuring the stability of the device during use. Both sides of the surface of the connecting rod 8 are provided with a slot 9, and one end of the locking rod 7 matches the slot 9. After the locking rod 7 is inserted into the slot 9, the movement of the connecting rod 8 can be restricted, thereby restricting the movement of the fastening frame 4, so as to ensure the stability of the connection between the main body 1 of the payment broadcasting device and the fastening frame 4.

[0024] The main body 1 of the payment broadcast device is equipped with a signal analysis module 15 and a broadcast module 16. The signal analysis module 15 is electrically connected to the broadcast module 16, and the broadcast module 16 is electrically connected to the speaker 2. The signal analysis module 15 can receive payment information and analyze it into a voice signal that the broadcast module 16 can recognize. The broadcast module 16 will then broadcast the voice information through the speaker 2 according to a preset broadcast method. This is a conventional technical means in this field, and therefore will not be discussed in detail here.

[0025] A fixing plate 11 is fixedly connected to the inner wall of the main body 1 of the payment broadcast device. Two springs 14 are fixedly connected to the surface of the fixing plate 11. The ends of the two springs 14 away from the fixing plate 11 are in contact with the surface of the display panel 3 to reset the display panel 3. A pressure sensor 13 is embedded inside the fixing plate 11. The pressure sensor 13 is electrically connected to the signal analysis module 15. A contact rod 12 is fixedly connected to the side of the display panel 3 near the fixing plate 11. The contact rod 12 corresponds to the pressure sensor 13 and is used to trigger the pressure sensor 13.

[0026] A pressing groove 10 is provided on one side of the main body 1 of the payment broadcast device. A pressure sensor 13 is also provided on the inner wall of the pressing groove 10. A power supply module is provided inside the main body 1 of the payment broadcast device to supply power to the device and ensure its normal operation. At the same time, the pressure sensor 13 in the pressing groove 10 is electrically connected to the power supply module. A fingerprint recognition system can also be set in the main body 1 of the payment broadcast device and work together with the pressure sensor 13 in the pressing groove 10. This way, the power supply module of the device can only be triggered after a specific fingerprint recognition is completed, so that the device can be put into a power-off and restart state to achieve the purpose of contact alarm.

[0027] The display board 3 includes a base plate 302 and a film layer 301. The film layer 301 is adhered to the base plate 302. The film layer 301 can be composed of two or three layers of film that are adhered to each other, so that the display board 3 has multiple opportunities for re-adhesion. After the payment QR code on the display board 3 is damaged or contaminated, the original damaged QR code can be removed by peeling off one layer of film layer 301, and then a new QR code can be attached to it to complete the replacement of the payment QR code.

[0028] Working Principle: In use, when unauthorized individuals attempt to replace a merchant's payment QR code, the pressure applied to the display panel 3 during the affixing of the new QR code causes the display panel 3 to move closer to the fixed plate 11, compressing the spring 14. This movement of the display panel 3 drives the contact rod 12 closer to the pressure sensor 13, triggering the pressure sensor 13. The pressure sensor 13 then triggers the signal analysis module 15, which transmits the information to the broadcast module 16, which plays it through the speaker 2, thus issuing an alarm to remind the merchant. Subsequently, when the merchant wants to deactivate the alarm, they can apply pressure to the pressure sensor 13 in the pressing groove 10, causing the power supply module to stop supplying power and the device to cease operation, thereby deactivating the alarm. This prevents unauthorized individuals from replacing the merchant's QR code, protecting the merchant's interests and improving the device's effectiveness.

[0029] Meanwhile, when the QR code is damaged or dirty and a new QR code needs to be replaced, the user can move the two levers 7 on both sides in sequence to make the two levers 7 move in opposite directions and separate them from the slot 9. This will allow the connecting rod 8 to move without obstruction. At this time, the fastening frame 4 can be separated from the main body 1 of the payment broadcast device by pushing the two connecting rods 8. Then, a layer of film 301 can be peeled off, and a new QR code can be attached to the new film 301. Finally, the fastening frame 4 and the display board 3 can be installed on the main body 1 of the payment broadcast device to complete the replacement of the QR code.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
