Abstract

The utility model relates to an electronic element, particularly an electronic firecracker. The utility model mainly solves the problem that the existing firecrackers are easy to hurt people and cause serious pollution. The utility model has the technical scheme that the signal output terminal of a remote control receiving circuit is connected with the signal input terminal of a single chip computer in a control circuit; the output terminal of the single chip computer U1 is respectively connected with the signal input terminals of a sound circuit and a lamplight circuit. The utility model has a promising prospect in the field of firecrackers.

Description

Electronic cracker

The utility model relates to electronic component, especially a kind of electronics firecracker.

At present, existing firecracker is easily hurted sb.'s feelings, and pollutes greatly, is eliminated gradually.

The purpose of this utility model is that the design by circuit provides a kind of and do not hurt sb.'s feelings, free of contamination novel electron firecracker.

The technical solution of the utility model: shake the signal input part of single-chip microcomputer in the signal output part connection control circuit of controlling receiving circuit, single-chip microcomputer U ₁The signal input part of an output termination sound circuit, the signal input part of an output termination light circuit.

Advantage of the present utility model because the design on the circuit makes the utility model both have traditional acoustooptical effect, can have been avoided the pollution of environment simultaneously again noise control in certain limit again.

Narrate embodiment of the present utility model in conjunction with the accompanying drawings.

During enforcement, photoelectrical coupler U in the sound circuit 4 ₆Meet preamplifier U ₇The pin 1 of (selecting BA328 for use), pin 3 meets audio-frequency power amplifier U ₈The pin 2 of (selecting LA4440 for use), audio-frequency power amplifier U ₈Pin 13 through capacitor C ₂₂, C ₂₃Meet loudspeaker SP.Remote-control receiving circuit 2 middle infrared (Mid-IR) receiving tube D ₁Meet amplifier U ₂The pin 1 of (selecting CX20106A for use).Photoelectrical coupler U in the light circuit 5 ₉Meet three utmost point T ₃Base stage, triode T ₃Emitter stage meet triode T ₆, T ₄, T ₅Colelctor electrode, triode T ₄～T ₆Emitter stage respectively through controllable silicon SCR ₁～SCR ₃Meet Holiday lamp L ₁～L ₃

Fig. 1 is the utility model fundamental diagram.Radiating circuit 1 sends signal, and receiving circuit 2 received signals also send signal to control circuit 3, by control loop 3 by level signal control sound circuit 4 and light circuit 5 work.Fig. 2 is the radiating circuit schematic diagram, and integrated circuit U is penetrated in keyboard 6 sending and receiving ₁The

12,13,14 of (selecting M50460-01 for use), pin 20 meets infrared transmitting tube LED.Fig. 3 is the receiving circuit schematic diagram.Amplifier U ₂Single-chip microcomputer U in the signal output part D102 connection control circuit of (selecting CX20106A for use) ₅The pin 3 of (selecting 8098).In the control circuit schematic diagram 4, control section is by latch U ₄(selecting 74LS373), memory U ₃(selecting 27512), single-chip microcomputer U ₅(selecting 8098) links.Single-chip microcomputer U ₅Output D101(be pin 13) connect the signal input part of sound circuit, but sheet machine U ₅Output D103(be pin 7) connect the signal input part of light circuit.

During work, with single-chip microcomputer U ₅(selecting 8098) initialization makes pin 13 and pin 7 be in low level, is subjected to this moment the sound of its control not rung the Holiday lamp L in the light circuit by the loudspeaker SP in the circuit ₁～L ₃Do not work.Press when shaking control button 6, signal is through emission integrated circuit U ₁(selecting M50460-01 for use) selects SE303A for use by infrared transmitting tube LED() launch infrared receiving tube D in the receiving circuit ₁(selecting PH302) received signal is through amplifier U ₂(selecting CX20106A for use) amplifies back input single-chip microcomputer U ₅Pin 3.If press be some big gun key f in the button 6 time, single-chip microcomputer U ₅Output D101(pin 13) and D103(pin 7) respectively high level signal is passed to sound circuit and light circuit.Signal is through preamplifier U in the sound circuit ₇(BA328) and audio-frequency power amplifier U ₈(LA4440) amplify the back by loudspeaker SP sounding.After light circuit is received high level signal, loop color lamp L ₁, L ₂, L ₃Glittering.If what press is a number in the big gun key 6 when key a-c or volume being set strong d, e being set, then single-chip microcomputer is correspondingly carried out and is revised a number register and volume register subprogram, makes the electronics firecracker finish function corresponding.
