Description

The color lamp electronic firecracker of sociable singing

The utility model relates to a kind of color lamp electronic firecracker of sociable singing, but especially a kind of recording playback can be used the color lamp electronic firecracker of sociable singing repeatedly.

The tradition firecrackers have the production history in more than 1,000 year, be the traditional celebrating articles for use of the domestic and international people, help rendered atmosphere, give grand, ardent and celebrate joyously impression, development along with spiritual civilization, people are after happiness is set off firecracker, notice more and more when setting off firecracker, to the pollution of environment, and the caused fire of explosive and to human injury's danger, therefore, some big and medium-sized cities have been put into effect the measure of No Fireworks successively, so, and when the celebrating happy festival time, people are owing to can not set off firecracker to show congratulation by traditional habit, and feel sorry, and lacking lively atmosphere and greatly inferior, people have developed various electronic firecrackers, in the electronic firecracker that existing market is sold, the number of patent application 97204023.4 electronic simulation primary and secondary firecrackers of my design, effect is true to nature liked by people, but lacks this recording and reproducing function of sociable singing, in the lively occasion in celebrating happy festival time, lacked some enjoyment true feeling blemish in an otherwise perfect thing.

The purpose of this utility model is the deficiency that will overcome above-mentioned prior art, but and a kind of recording playback speech IC is provided, allow relatives and friends express own good the wish, plays blessing personally and the singing of oneself, for example: the congratulation birthday: " happy birthday to wish you! ", sing " happy birthday to wish you " song; Celebrate New Year: " happy New Year, and may you be hapy and prosperous! " and sing and " celebrate New Year, congratulate you! " song, cooperate around chasing of " good fortune " word and run color lamp to show luckiness, can light the firecrackers fuse simultaneously, set off loud melodious primary and secondary electronic firecracker sound and with glittering in the rhythm of primary and secondary report, the big or small firecracker cylinder; Strengthened happy atmosphere effectively, made the people feel more warm, warm, lucky and celebrating.

The purpose of this utility model is achieved in that it moulds box by red hexangle type audio amplifier and be printed on the big word of " good fortune ", " high post ", " longevity ", " happiness " and so on (an optional word) moulding the box panel centre, redness is housed on every side chases the color lamp of running; Mould printed circuit board (PCB), transformer and the loudspeaker of being made up of electronic devices and components be installed in the box, mould box below, hang a lot of red transparent plastic firecracker cylinder that bulb is housed.The knitting arrangement mode of firecrackers simulating shape tradition master and slave type firecrackers weaves primary and secondary firecrackers chain, orlop at the firecrackers chain, the fuse that fires and the ancient money, the ribbon that hang with different mode are housed, make this electronic firecracker form the whole structure of upper, middle and lower balanced, symmetrical.It is characterized in that: chase the color lamp of running after the energising and begin around " good fortune " word to run, can be with the congratulatory words that recorded or song by pressing SB ₂Playback switch plays back.Simultaneously, can light the combustion big gun fuse in the electronic firecracker, temperature-sensitive element RT in the circuit is touched to be closed, through rise a control circuit, the time control circuit, trigger primary and secondary firecrackers sound source circuit and the sound-source signal of output is delivered to the synchronous compound driver module of acousto-optic remove to drive loudspeaker, send primary and secondary firecrackers sound, simultaneously, the The Trigger of Bidirectional Triode Thyristor end in the control light-operated circuit, the bulb group that it is driven in the firecracker cylinder is glittering with the rhythm of the primary and secondary firecrackers sound.

Adopted the color lamp electronic firecracker of the sociable singing of this spline structure, had the civilization of setting off, novelty, safety, health and nonpollution environment, can use repeatedly.
