Abstract
The utility model relates to an electronic flash firecracker which can be used for people's festivals, comprising an outer housing (1), a speaker (2), a power supply circuit (3), a flash circuit (4), a generating circuit (5) of firecracker sound and an audio amplifying circuit (6). The utility model has the advantages of no danger, no environmental pollution, long service life, repeated use, uneasy for fire happening, vivid sound, synchronous acoustic-optic, etc.
Description
The utility model is a kind of electronic flash firecracker.
Its deficiency of the firecracker of Chu Shouing is certain danger to be arranged when being to set off in the market, and contaminated environment, very easily breaking out of fire.
The purpose of this utility model is to avoid the weak point of prior art, provides a kind of new firecracker, i.e. the electronic flash firecracker.
The purpose of this utility model can reach by following measure.The electronic flash firecracker by: shell (1), loudspeaker (2) are formed (seeing accompanying drawing one), it is characterized in that shell (1) built-in one the flash of light sound-producing device comprise: power circuit (3), flasher circuit (4), firecracker sound generation circuit (5), audio amplifier circuit (6) (seeing accompanying drawing two).
Operation principle of the present utility model is as follows: electronic flash firecracker circuit is taken place by power supply, flash of light, firecracker sound and four partial circuits of audio frequency amplification are formed.The power supply of electronic flash firecracker uses Alternating Current Power Supply, also can use direct current supply.The 220V civil power is through R during Alternating Current Power Supply
1Current limliting; D
1Supply with capacitor C after the rectification
1Be used to light flash tube, pass through R simultaneously again
2To C
2Charging, capacitor C when controllable silicon STR conducting
2To transformer T
1Elementary discharge, at T
1secondaryly just produce 10,000 volts of above high pressure, excite flash tube luminous.Another road civil power is depressurized to 6V C after rectification through transformer
3Filtering is supplied with firecracker sound and is taken place and audio amplifier circuit.Firecracker sound generation circuit adopts simulation firecracker sound integrated circuit KD-5601, IC
1The firecracker sound audio signals that sends is through C
4Be coupled to the TBA820M power amplifier integrate circuit and amplify, promote the loudspeaker sounding.The control utmost point that audio signal after the amplification is connected to STR simultaneously again triggers the controllable silicon conducting, makes flash tube luminous, produces the effect of sound flash synchronization.
When with direct current supply, (see accompanying drawing 3), triode BG
1,
2Feedback resistance R, the circuit that oscillation transformer T forms produces self-oscillation, boosts by transformer and receives A, the B point supply flasher circuit of accompanying drawing two circuit at the voltage of the about 300V of secondary output, and ten, one of 6V battery is connected to C, D point and supplies with IC
1And IC
2
The utility model is compared with existing technology and is had the following advantages:
1, is safe from danger, do not have air pollution.
2, the life-span long, can use repeatedly.
3, be difficult for breaking out of fire.
Accompanying drawing drawing explanation of the present utility model:
The outline drawing of figure one, shell;
Figure two, electronic flash firecracker electrical schematic diagram;
Figure three, inverter electrical schematic diagram.
Embodiment:
The loudspeaker of electronic flash firecracker (2), power circuit (3), flasher circuit (4), firecracker sound generation circuit (5), audio amplifier circuit (6) (seeing accompanying drawing two) device are contained in the rectangle plastic casing, and the flash lamp pore (seeing accompanying drawing one) of speaker hole and loam cake transparent plastic is opened in the front.Also can change over the shell of various moulding, main points are outstanding flash tubes, do not influence the loudspeaker sounding and get final product.
After circuit in the accompanying drawing two installs, must adjust W to suitable acoustics.
Numerical value is indicated in accompanying drawing two, the accompanying drawing three, be need to prove T
1Available finished product flash lamp triggers line chart, T
2Available finished product 3W power transformer, T can use finished product flash lamp step-up transformer, the data that the concrete wiring of KD-5601 provides with reference to producer.
