Abstract
The utility model discloses an electronic firecracker, particularly a hand-held multifunctional electronic firecracker. The utility model is composed of a hand-held handle, a hanging ring, a decorative piece body and a plastic firecracker, wherein a battery, a firecracker sound simulating circuit and a loudspeaker audio power amplifier circuit are arranged in the hand-held handle. The utility model can simulate the firecracker sound, can send out the sounds of 'Plutus comes' and 'congratulation and make a pile', and can also be used as a simple loudspeaker with which children can speak and sing. The hand-held multifunctional electronic firecracker has the advantages of beautiful appearance, reasonable design, safe and convenient operation, etc., and is very suitable for children to play and for decoration.
Description
The utility model relates to a kind of electronic firecracker, particularly a kind of hand-held type multifunctional electronic firecracker.
Firecrackers are as one of Chinese four inventions---an important application of gunpowder, it is given red-letter day of people and has increased many cheerful and light-hearted atmosphere, but development along with society, people are when setting off firecracker cheerfully, notice the pollution of firecrackers more and more to environment, therefore in recent years, some big and medium-sized cities have been put into effect the measure of No Fireworks successively, so, children have just lost a lot of enjoyment when celebrating a festival in the New Year, therefore be badly in need of a kind of for children play, safe and reliable electronic firecracker toy again.
The purpose of this utility model is exactly that a kind of reasonable in design, easy to carry, good looking appearance, safe and reliable hand-held type multifunctional electronic firecracker will be provided.
For achieving the above object, the utility model adopts technical scheme as described below: the hand-held type multifunctional electronic firecracker is made up of hand holding handle, link, decorative element, plastics firecrackers, No. 2 dry cells of 3 joints are housed in the hand holding handle, firecrackers acoustic simulation circuit, speech simulation phonation circuit, loudspeaker audio-frequency power amplifier circuit are housed in the hand holding handle of dry cell front end.This end of hand holding handle hangs with decorative element, and the decorative element lower end hangs with the plastics firecrackers, and the profile of decorative element can be the triangular cone that is docking together, and also can be Chinese palaiotype pavilion, lantern, pagoda shape.
Loudspeaker audio-frequency power amplifier circuit is by two power amplification ic chips
3KD-28, microphone M, capacitor C
