Abstract
The utility model relates to an electronic firecracker, which is used for replacing the traditional chartaceous firecracker. The utility model is composed of a sound control circuit, a light control circuit and a power circuit and mainly comprises a voice circuit, an amplifier, a loudspeaker, a light controller, a drive circuit and a color lamp string. The analog electrical signal of the firecracker sound, which is stored in the voice circuit, drives the loudspeaker to send out the firecracker sound after amplified by the amplifier. Meanwhile, the color lamp string send out light from bottom to top by the control of the light controller through the drive circuit, and the emulational firecracker effect with acoustic-optic coordination can be achieved. The utility model eliminates the defects of environmental pollution and the health hazards caused by the combustion of the traditional chartaceous firecracker, and the utility model with high durability, saves the great expense of the firecracker consumption for people.
Description
The utility model belongs to a kind of electronic firecracker, can be used to substitute traditional papery firecrackers.
For a long time, people custom is set off firecracker on New Year's Day or other festivals, during weddings and funerals.And traditional firecrackers are mainly by gunpowder and made of paper causing, and accident such as fire hazardous, injures and deaths when setting off causes immeasurable loss.Simultaneously, in the process of setting off firecracker, produce a large amount of paper scrap and refuse, cause serious pollution for the environmental sanitation in town and country; Smog and gases such as the many harmful phosphorus that produces, sulphur, carbon monoxide also jeopardize the healthy of people.
In recent years, for fear of setting off the harm that causes, the someone adopts magnetic tape sound reproducer, release prerecording under the control of firecrackers sound on the tape at button, set off the papery firecrackers to substitute, coordinate, can not reach the effect similar to the papery firecrackers but lack the unified of light harmony.
The purpose of this utility model be a kind of acousto-optic of design in conjunction with and can reach electronic firecracker to the similar effect of papery firecrackers, fundamentally overcome the danger of traditionally on paper firecrackers, also can remedy the flashless deficiency of tape playback.
Electronic firecracker of the present utility model mainly is made up of sound control circuit, light-operated circuit, power circuit, sound control circuit comprises sound circuit, amplifier, loudspeaker, sound circuit leaves the firecrackers acoustic simulation signal of telecommunication of encoded compression in advance among the built-in ROM in, its output termination amplifier in, the output of amplifier connects loudspeaker ［ 5 ］; Light-operated circuit comprises lamp dimmer, drive circuit and Color lamp string ［ 6 ］, and lamp dimmer output is joined by drive circuit and Color lamp string.Send operational order by gauge tap like this, device can obtain the effect of firecrackers sound and color lamp flash synchronization.
The advantage that adopts above-mentioned technical solution is conspicuous, not only eliminated and seted off many drawbacks that the traditionally on paper firecrackers are produced, reach the optoacoustic effect similar to setting off true firecrackers, and, because this device adopts advanced IC chip, volume is little, and is simple in structure, easy to operate, durable in use.Buy one and use only throughout the year, saved the expense of making a big purchase firecrackers in large quantities for people.
It is following that the utility model is described in further detail with reference to accompanying drawing.
Fig. 1 is the apparatus structure schematic diagram of electronic firecracker;
Fig. 2 is circuit theory diagrams;
Fig. 3 is the printed chassis figure of electronic firecracker.
In the apparatus structure schematic diagram of the electronic firecracker of Fig. 1, ［ 1 ］ is crust of the device, and ［ 2 ］ are gauge tap K1, and ［ 3 ］ are gauge tap K
2, ［ 4 ］ are the signal accessory power outlet, and ［ 5 ］ are loudspeaker, and ［ 6 ］ are Color lamp string, and ［ 7 ］ are circuit substrate, ［ 8 ］ are the device base plate.Circuit theory diagrams and explanation thereof are seen in connection between each parts.

When the power output of this device can not meet the demands, can signal accessory power outlet ［ 4 ］ be connected with the external input socket of videocorder or expander with two-way plug, audio signal is further amplified output.
Color lamp string ［ 6 ］ is that the bulb fraction set is weaved into firecrackers type Color lamp string, and color can be allocated by color according to actual needs, can be that whole red, whole white or multiple color interval are arranged, and helps selecting for use of the different occasions of weddings and funerals like this.The Color lamp string of present embodiment is little neon lamp, can also use miniature bulb, light emitting diode and various optic fibre carrier as required.The bulb quantity of Color lamp string can be determined according to the loud number of manufacturing firecrackers.
Fig. 3 is the printed chassis figure of electronic firecracker, and the frame of broken lines of figure top is a sound control circuit, and circuit is drawn M, N, four binding posts of X, Y, connects switch, loudspeaker and binding post.The frame of broken lines of figure below is a light-operated circuit, L
