Description

A kind of voice firecracker

Technical field

The utility model relates to a kind of firecracker, especially a kind of voice firecracker.

Background technology

Various firecracker kinds in the market are more traditional single, lack colourful ceremony atmosphere, if put firecracker also the sound speech of congratulation in red-letter day, cheerful and light-hearted music etc., people just more can experience the atmosphere in red-letter day.

Summary of the invention

The purpose of this utility model provides a kind of colourful voice firecracker with amusement entertaining.

The utility model is realized by following scheme: be that the firecracker of reeling in the center constitutes by the happiness mould with the box, be provided with voice MCU in the happiness mould, it is by loudspeaker, buzzer, battery case, elastic clip constitutes with the IC circuit board that is provided with the good speech of congratulation music of imprinting, wherein circuit is made up of with the IC integrated circuit that is connected with loudspeaker the control circuit that is connected to buzzer, the battery case battery is connected to circuit with electroplax provides power supply, the elastic clip two ends are connected on the power line, one side of box is provided with a storehouse to the outer opening of box, it is corresponding with spring clip that a wall relative with opening has an insulation mouth in the storehouse, the fuse that is made of big cannon is housed in the storehouse, its lead-in wire is connected with the firecracker end leads, the insulating trip that is connected with firecracker with line inserts between the spring clip by insulation mouth in the storehouse, makes circuit be in the deenergization state.

Characteristics such as the utility model is simple in structure, and is convenient and practical, and result of use is good.

Description of drawings

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the utility model embodiment electrical block diagram.

The specific embodiment

The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.As shown in the figure, the utility model is that the firecracker of reeling in the center constitutes by the happiness mould with this box, establish by loudspeaker 2 in the happiness mould 1, buzzer 3, battery case 4, the voice MCU of elastic clip 5 and IC circuit board 6 formations that are provided with the good speech of congratulation music of imprinting, wherein circuit is made up of with the IC integrated circuit that is connected with loudspeaker 2 sound control circuit that is connected to buzzer 3 (in the frame of broken lines of Fig. 2), battery in the battery case 4 provides voltage-stabilized power supply to circuit, and elastic clip 5 two ends are connected on the power line; One side of box 1 is provided with the storehouse 7 of an external opening, it is corresponding with spring clip 5 that corresponding wall with opening has an insulation mouth 8 in the storehouse 7, the insulating trip 9 that is connected with outer firecracker binding of reeling with line inserts between the spring clip 5 by insulation mouth 8, makes circuit power be in off-state.The fuse that is made of big cannon is housed in the storehouse 7, and its lead-in wire is connected with the firecracker end leads.

In the use, earlier the firecracker of reeling is opened, the line that pulling links to each other with insulating trip 9 when being opened to certain position is extracted insulating trip 9 out from spring clip 5, circuit power is connected, circuit is started working, voice MCU sends congratulatory words and music, the lead-in wire that fires off crackers sounds firecracker, after firecracker has rung, congratulatory words that voice MCU still sends and music be (about one minute) after a period of time, as also wanting voice MCU work, as long as have sound or vibration to make buzzer 3 work, can begin to play voice again after just can triggering TG, capable of circulation always.

Claims (1)

1, a kind of voice firecracker, by the happiness mould with the box is that the firecracker of reeling in the center constitutes, it is characterized in that: be provided with voice MCU in the happiness mould, it is by loudspeaker, buzzer, battery case, elastic clip constitutes with the IC circuit board that is provided with the good speech of congratulation music of imprinting, wherein circuit is made up of with the IC integrated circuit that is connected with loudspeaker the sound control circuit that is connected to buzzer, the battery case battery is connected to circuit with circuit board provides power supply, the elastic clip two ends are connected on the power line, one side of box is provided with a storehouse to the outer opening of box, it is corresponding with spring clip that a wall relative with opening has an insulation mouth in the storehouse, the fuse that is made of big cannon is housed in the storehouse, its lead-in wire is connected with the firecracker end leads, the insulating trip that is connected with the firecracker hanging wire with line inserts between the spring clip by insulation mouth in the storehouse, makes circuit be in the deenergization state.
