Description

Electronic cracker with sound and light effects

The utility model relates to a kind of electronic firecracker.

People are on New Year's Day or other festivals or when celebrating, set off firecracker always to increase atmosphere, at present, in these occasions is that the papery firecrackers of raw material are in the majority to set off with gunpowder still, paper scrap disorderly flies during this firecracker setting-off, and is not only dirty and messy, and the smog serious environment pollution, the spark that fires also should cause fire, sets off firecracker and advise replacing to have the acoustic audiotape of firecrackers in indivedual areas also regulation control.Recently, though some electronic firecrackers also occurred, they often only possess acoustics.

The objective of the invention is to design a kind of electronic firecracker, this electronic firecracker not only possesses the security of general electronic firecracker, also more approaches the actual sound and light program of papery firecrackers simultaneously.

The utility model is achieved in that a kind of electronic firecracker with sound and light program, is made up of circuit box, governor circuit, Simulation firecracker, collection tube, pronunciation circuit.Simulation firecracker is divided into upper and lower casing two parts, and upper shell is transparent tubular, in adorn a light-emitting component and electromagnet, lower house is tubular, in adorn a permanent magnet; Collection tube is provided with pronunciation circuit for the bottom has the basin body of interlayer in the interlayer, loudspeaker and light-emitting component are housed on the interlayer upper spacer; Governor circuit is installed in the circuit box, and Simulation firecracker is hung under circuit box by the control signal wire harness.

Advantage of the present utility model is: avoid the dirty and messy phenomenon that paper scrap is scattered and causes when setting off firecracker; The fire of the Mars initiation that produces when preventing and the air pollution that smog causes because of firecracker setting-off; The volume of firecrackers can be regulated at any time with the actual conditions of scene, and reusable.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

From Fig. 1 as seen, the utility model is by circuit box (1), and governor circuit (2), Simulation firecracker (3), collection tube (4) and pronunciation circuit (5) are formed.Governor circuit (2) is contained in the circuit box (1), and its power switch (SW) is contained on the shell of circuit box (1); Simulation firecracker (3) is hung under circuit box by signal wire harness (23), pronunciation circuit (5) is installed in the interlayer of collection tube (4) bottom, light-emitting component (52) and loudspeaker (SP) are housed on the interlayer upper spacer (41), can be provided with guard (6) on light-emitting component (52) and the loudspeaker (SP), collection tube (4) is provided with the volume switch (53) of pronunciation circuit (5).

From Fig. 2, Fig. 3 as seen, Simulation firecracker (5) is made up of upper shell that is transparent tubular (31) and tubular lower house (32), light-emitting component (21) and electromagnet (22) are housed in the upper shell, permanent magnet (321) is housed in the lower house, when in the magnet spool during no current, the last lower house of Simulation firecracker (3) is pull-in on together because of the cause of permanent magnet (321).

From Fig. 4 as seen, governor circuit (2) is by sending the IC chip (IC of triggering signal in each output in proper order ₁) be maincenter, present embodiment is with can be successively at output Q ₁-Q ₁₅On send the integrated circuit die I C of triggering signal ₁Be example, at integrated circuit die I C ₁V _DDThe end with power supply between be connected in series a power switch (SW), input OSC ₁, OSC ₂An external oscillating crystal (X ' TAL), output Q ₁-Q ₁₅Each external light-emitting component (21) and electromagnet (22).

As seen from Figure 5, pronunciation circuit (5) is by battery, vibration trigger switch (51), Music Clip IC ₂, volume switch (53), amplifier (54), loudspeaker (SP), light-emitting component (52) form.Vibration trigger switch (51) is made up of flexible member with electric conductivity (511) and triggering element (512), amplifier can be with a single tube amplifier, also can select Darlington amplifiers such as (Darlington) for use, light-emitting component (52) can be provided with several according to circumstances on the dividing plate (41) of collection tube (4), present embodiment is an example with two groups of pronunciation circuits (5) and a light-emitting component (52) only.

The course of work of present embodiment is: at first connect power supply, turn on the power switch (SW), the integrated circuit die I C of governor circuit (2) ₁Can produce some triggering signals, and successively from Q ₁-Q ₁₅End output is when first triggers the signal of telecommunication from Q ₁During output, with Q ₁The holding wire (23) that links to each other passes to the interior light-emitting component (21) of coupled Simulation firecracker (3) and the coil of electromagnet (22) with this signal, and at the last induced field that produces of electromagnet (22), this magnetic field makes the magnetic pole on electromagnet (22) and permanent magnet (321) contact-making surface be the same sex, repel and make the last lower house separation of Simulation firecracker (3) mutually, go up at light-emitting component (21) simultaneously and produce the moment optical signal.The lower house (32) that separates is fallen under the gravity effect in the collection tube (4), and bump dividing plate (41) makes the shock-activated switch (51) that is contained on the dividing plate (41) send triggering signal, and triggers Music Clip IC ₂, Music Clip (IC ₂) in the explosion sound equipment of default a succession of firecracker after amplifier (54) amplifies, send the sound of ringing accordingly by loudspeaker, impel light-emitting component constantly glittering simultaneously with sound equipment.Integrated circuit die I C when governor circuit (2) ₁Pass through Q ₂When exporting second triggering signal, will make and output Q ₂Second Simulation firecracker (3) that links to each other repeats said process.

In the present embodiment, pronunciation circuit (5) is made up of two groups of identical pronunciation circuits, and send the sound of ringing by loudspeaker separately, this mainly is in order to make their mutual compensation, make that continuously firecrackers sound is more true to nature, simultaneously, the output volume of each loudspeaker all can be regulated by relevant volume switch (53).

" set off " when firecrackers and to finish, can turn-off the power supply (SW) of governor circuit (2), integrated circuit die I C ₁To no longer export triggering signal, the non-inductive magnetic field of electromagnet (22) in all Simulation firecrackers (3), the lower house (32) of the Simulation firecracker of " setting off " (3) will no longer not come off, and pronunciation circuit (5) does not no longer send the sound of ringing because of there being new triggering signal.At this moment, the lower house (32) that has come off can be placed on the upper shell (31) again, under the effect of permanent magnet (321), lower house be solidified as a whole, in order to reusing next time.

Each light-emitting component in the utility model can be selected light emitting diode for use, also can select bulb for use.The power supply of governor circuit and pronunciation circuit can adopt utility power also can adopt separately independently power supply.
