Abstract
The invention discloses an electronic firecracker, belonging to the field of an entertainment device. Particularly, the invention relates to an electric firecracker capable of generating the sound of firecrackers by using the power energy, aiming to provide a safe and pollution-free electronic firecracker with the firecracker effect. The electronic firecracker comprises a columnar body, the structural point is that a pushbutton switch is arranged on a bottom face, the inner part of the columnar body is provided with a circuit; the output end of an integrated chip in the circuit is connected with a base electrode of a dynatron through a resistor; the input end of the integrated chip is connected with the pushbutton switch, the dynatron collector is connected with a loudspeaker.
Description
Technical field:
The invention belongs to the entertainment device field, relate in particular to a kind of electronic fire cracker that utilizes electric energy to produce noise of firecrackers.
Background technology:
The set off fireworks existing two thousand years of history of firecracker of China." New Year's Eve in the noise of firecrackers " is the traditional custom that long history is arranged, and is the important component part of Chinese national culture.Whenever celebrating date, particularly Spring Festival, people are in order to increase the happy atmosphere in red-letter day, from the junior one to ten five, and a large amount of firecracker of setting off fireworks especially.But set off firecrackers a lot of drawbacks are arranged also, such as atmosphere pollution, environmental pollution, safe calico, potential safety hazard etc.If there is a kind of product can have the effect of firecracker not have again above-mentioned drawback, that is just excellent.
Summary of the invention:
The object of the invention is to provide a kind of have firecracker effect and safe, free of contamination electronic fire cracker.
For achieving the above object, the present invention adopts following technical proposals, the present invention includes cylinder, and its structural feature is to be provided with press button on the cylindrical bottom surface, and cylinder inside is provided with circuit; The output of the integrated chip in the described circuit is connected with transistor base by resistance, and the integrated chip input is connected with press button, and transistor collector is connected with loudspeaker.
As a kind of preferred version, integrated chip of the present invention adopts KD-5601 pattern onomatopoeia integrated circuit.
As another kind of preferred version, triode of the present invention adopts 9013 model triodes.
Beneficial effect of the present invention:
The present invention mainly comprises cylinder and circuit, and is simple in structure, is easy to promote; During use, as long as press the button switch, will send loud noise of firecrackers, simple to operate, people had both enjoyed puts the happy of whip, and safe, pollution-free.
Description of drawings:
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is circuit theory diagrams of the present invention;
1 is cylinder among Fig. 1, and K is press button.
The specific embodiment:
As shown in Figure 1, 2, the present invention includes cylinder 1, be provided with button switch K on the bottom surface of cylinder 1, cylinder 1 inside is provided with circuit; The output of integrated chip U in the described circuit is connected with triode VT base stage by resistance R 2, and integrated chip U input is connected with button switch K, and triode VT colelctor electrode is connected with loudspeaker B.
Described integrated chip U adopts KD-5601 pattern onomatopoeia integrated circuit.
Described triode VT adopts 9013 model triodes.
As shown in Figure 2, main circuit of the present invention will adopt simulated sound integrated circuit U, and " firecracker " sound that produces is really true to life, and can reach the stage of mixing the spurious with the genuine.K is the pocket buttons switch, works to trigger the work of U internal circuit.At ordinary times, circuit is in static off position, and whole circuit power consumption is very small, and total current only is about 1 μ A.When having the people to press K, the trigger end TG of U will obtain the positive pulse signal of telecommunication, the U internal circuit is subjected to triggering work, its output OUT just can export the interior storage simulation firecracker sound signal that reaches 20s for a time, after transistor VT power amplification, promote loudspeaker B and send loud " firecracker " sound.In the circuit, R1 is the external oscillation resistance device of U, the speed speed of its resistance size impact " firecracker " sound and tone height.Capacitor C is mainly used in some discordant harmonic components in the elimination simulated sound integrated circuit U institute output signal, makes " firecracker " sound more clear and melodious loud.The resistance R 2 main metering functions that rise can prevent effectively that the too high power amplification triode of indivedual β values from producing self-excitation phenomena.
U selects KD-5601 pattern onomatopoeia integrated circuit, and its adopts black rubber seal dress form to be produced on the little printed circuit board that a size is about 23mm * 14mm, and gives peripheral cell welding foot hole is arranged, and uses easily.The major parameter of KD-5601: exemplary operation voltage is 3V, trigger end allow input voltage range-0.3～+ 0.3V, audio output drive current 〉=1mA, static power consumption≤1 μ A, serviceability temperature scope-10 ℃～60 ℃.
