The purpose of this utility model can also reach by following measure: integrated circuit CW9599 can adopt HC898.Box body is the same cylindrical with the outward appearance of traditional firecracker, is made up of two parts, connects as one by the edge bayonet socket.

Compared to existing technology, the utlity model has following advantage:

1, adopt electronic circuit, it is clear and melodious more melodious than traditional firecracker to send the sound;

2, the most suitable indoor be that unit uses with the family, sound is adjustable, has avoided as much as possible other people are disturbed, safe in utilization, both can intersperse and beautify the room, can replace traditional firecracker again, satisfy people's active demand to traditional habit in today of Fireworks Prohibited;

3, one-time investment is benefited for many years;

4, design concept novelty, simple in structure:

5, make simply, easily produce

The explanation of accompanying drawing drawing:

Fig. 1 is an electrical schematic diagram of the present utility model

Fig. 2 is the wiring diagram of circuit board

Fig. 3 is the box body structure schematic diagram of opening

Fig. 4 is monnolithic case figure

Embodiment describes the utility model in detail below in conjunction with accompanying drawing

Design philosophy of the present utility model is: utilize the language integrated circuit to make acousto-optic synchronous, be used to simulate fireworks and firecrackers, it is produced and the similar sound and light program of traditional fireworks and firecrackers, reach the purpose of enlivening celebrating atmosphere in red-letter day.For this reason, core circuit of the present utility model adopts an extensive CMOS integrated circuit CW9599.Also can use HC898, the simulation sound of the good various specific fireworks and firecrackers of its storage inside, its sound kind is 8 its 1 pin and transistor V ₆Base stage be connected V ₆The triode of using for amplifying signal select 9013 for use, triode V ₆Colelctor electrode connecting loudspeaker BL, loudspeaker BL selects 8 Ω for use.Raise province device BL and potentiometer RP and be in series, the effect of RP is the volume of regulating loudspeaker, and the other end of potentiometer RP links to each other with power supply, and power supply is the 3V dc source, No. 5 battery two joints.2 pin of integrated circuit CW9599 link to each other with push switch S.The effect of push switch S is to select the sound.The other end of push switch S and triode V ₆Emitter stage link to each other.The utility model drives bulb HL ₁, HL ₂, HL ₃, HL ₄, HL ₅The triode of illuminating is set to 5, selects for use 9015 to be V ₁, V ₂, V ₃, V ₄, V ₅, triode V ₁Base stage and 6 pin of integrated circuit CW9599 join, colelctor electrode is connected with bulb HL ₁, triode V ₂Base stage and 7 pin of CW9599 join, colelctor electrode is connected with bulb HL ₂Triode V ₃Base stage and 8 pin of integrated circuit CW9599 join, colelctor electrode is connected with bulb HL ₃Triode V ₄Base stage and 9 pin of integrated circuit CW9599 join, colelctor electrode is connected with bulb HL ₄Triode V ₄Base stage and 10 pin of integrated circuit CW9599 join, colelctor electrode is connected with bulb HL ₅Bulb HL ₁, HL ₂, HL ₃, HL ₄, HL ₅The other end be connected in series mutually, the tail end after the serial connection is connected with 11 pin of integrated circuit CW9599,11 pin link to each other with power supply.CW9599 12,13, the pin resistance R of connecting ₁, resistance is 240K.Transistor V ₁-V ₅Emitter stage be in series series connection back and triode V ₆Emitter stage be connected V ₆Select for use 9013 emitter stages to link to each other with ground wire
