Has above-mentioned every shortcoming at traditional firecrackers, just creativity and innovation this electronic firecracker, this electronic firecracker mainly is the effect of the electronic circuit that comprised of its inside of mat, can produce " sound, light " effect of simulation in " lighting " back, in order to replace traditional firecrackers; Electronic firecracker reduce to pollute and dangerous aspect be superior to traditional firecrackers really far away, what particularly traditional especially firecrackers can not be by comparison aspect reusable.
The object of the present invention is to provide a kind of " electronic firecracker ", the main key that " electronic firecracker " of the present invention lights action is all to be provided with on the various electronic firecrackers contact lever, connect inner contact circuit with this contact lever, so when using, only need electronic firecracker is driven and sound, the light effect of generation expection at every turn with the contact lever on the hand touch electronic firecracker.
The present invention's sound, light effect aspect are to switch switch by the control module of a sequential control circuit or to be controlled, and can make the sound of " electronic firecracker ", the generation of light can accept control individually, reaching preferable Expected Results, and can be used in decoration function separately.
The present invention's's " electronic firecracker " firecrackers individuality can be made into different pattern such as serial type firecrackers, row's type firecrackers or single-shot type firecrackers so that different user demands to be provided.
Below by giving an example, the present invention will be described with reference to accompanying drawing.Wherein
Fig. 1 is the circuit diagram of the present invention's " electronic firecracker ".
Fig. 2～Fig. 4 is the outside drawing of various different firecrackers bodies manufactured according to the present invention.
Number in the figure is described as follows:
(1) serial type firecrackers (2) row's type firecrackers
(3) single-shot type firecrackers (4) contact lever
(41) change-over switch (5) bulb
(6) lampshade (7) contact circuit
(8) positive trigger-type square-wave generator (81) (82) square-wave generator
(83) control module (9) acoustical generator
(91) NOT-AND gate (92) saw-toothed wave generator
(93) assorted signal generator (94) light driving circuit
(95) amplifier (42) selector switch
(811) (812) (813) resistance
(821) (822) (823) capacitor
At first referring to Fig. 2～Fig. 4, shown in be each embodiment of the present invention's " electronic firecracker ", the outward appearance of firecrackers can be made into and is similar to traditional various firecrackers, as row's type firecrackers (2) of the serial type firecrackers (1) of Fig. 2, Fig. 3 or as the single-shot type firecrackers (3) of Fig. 4.No matter but which kind of pattern firecrackers make, must comprise a series of bulbs (5) in it and cover in the outside lampshade (6) of bulb (5), and make it have lighting effects, the firecrackers of each pattern all have a contact lever (4) simultaneously, when each user touches this contact lever (4), the capital makes it touch coupled contact circuit (7), thereby starts inner circuit.
So only from the schematic representations form of Fig. 2～Fig. 4 two characteristics of the present invention as can be seen just, that is:
1. the present invention can replace various gunpowder firecrackers, thereby can be made into various firecrackers style, with the person's of being used the custom and the market demand.
2. the present invention has changed the two traditional line ways of contact aspect startup, and adopts the mode that touches startup.
Internal circuit configuration of the present invention is referring to Fig. 1, by circuit diagram shown in Figure 1 circuit characteristic of the present invention as can be seen is that input at positive trigger-type square-wave generator (8) is connected with contact circuit (7), input at this contact circuit then is connected with contact lever (4), in case when being touched, can trigger contact circuit (7) and then start positive trigger-type square-wave generator (8) with the output square-wave signal at contact lever (4).
In use, at first need adjust selector switch (42) to select the firecracker setting-off time, after selecting switch to adjust, as long as the user touches bar (4), electric current just flow through resistance (811), capacitor (821) (or (812), (822)) enters positive trigger-type square-wave generator (8) and generation is enough to the square-wave signal of guide sound, light.This square-wave signal is controlled the flicker of light via drive circuit (94) in the part of control light; In the part of control sound then via two square-wave generators (81) (82) to produce neither synperiodic square wave, again through NOT-AND gate (91) to produce square wave irregular and the different time constant.What be connected NOT-AND gate (91) back is a saw-toothed wave generator (92) and an assorted signal generator (93), the former damping time constant is determined by resistance (813) and capacitor (823) in Unit two, the latter's bias voltage is then controlled by resistance (813), when aforementioned square wave is transported to saw-toothed wave generator (92), the assorted signal generator (93) of warp is afterwards to form basic firecrackers audible signal again can to decay to sawtooth waveforms, and this signal can be produced the sound of similar firecrackers afterwards by acoustical generator (9) output via amplifier (95).
