Abstract
The utility model relates to an electronic device which generates traditional fireworks and firecrackers sound and light effects by an electronic element, comprising an oscillator and an amplifier. The power of the entire device is provided by a battery. The device has safety, no harm, small noise and low cost, the utility model is portable, and the utility model is an ideal amusement device.
Description
The present invention is a kind of electronic installation that produces traditional fireworks sound, light effect with electronic devices and components.
Traditional fireworks, not only noise is big, pernicious gas is seriously polluted, but also usually causes personal injury, breaking out of fire.By electronic technology, produce the electronic firecracker of nothing harm, safety, imperative.
Once the someone utilized recorder to play the effects,sound that method produces firecrackers of sending out of firecrackers sound tape, the disadvantage of the method is to have only the sound of firecrackers and the profile and the flash effect that do not have firecrackers, and noise is big, carry inconvenience, price is expensive, can not popularize use, especially be not suitable for children and use.
The objective of the invention is to produce with electronic circuit the effects,sound of traditional fireworks, form the profile of firecrackers and produce flash effect with the electronics shiner, the sound and flash of light simultaneously realizes synchronously.Whole device provides electric energy by battery.
This device safety, nothing endanger, noise is little, easy to carry, cost is low, is the desirable entertainment devices of children.
The electronic circuit that produces the firecrackers sound mainly is made up of oscillator and amplification system, and the firecrackers sound is sent by loudspeaker, and the electron luminescence thing of Simulation firecracker flash effect usually adopts light emitting diode.In order to realize the sound and flash synchronization, this device also is provided with the sound and gathers circuit and counting, decoding circuit.
Accompanying drawing 1 is to implement a kind of electronic circuit schematic diagram of the present invention.
In accompanying drawing 1, KD-5601 is a firecrackers sound oscillation acoustical generator, and the resistance that changes R3 can change the tonequality of firecrackers sound; LM386 and peripheral cell thereof are formed audio-frequency amplifier, are used for the signal that KD-5601 sends is amplified, and promote loudspeaker and send the firecrackers sound.LD4017 is counting, decoder, and it makes 10 (or more) light emitting diode random light emission and sound, phototiming under sequence circuit NE555 and sound Acquisition Circuit V1 control.
Debug step: at first the circuit diagram of adjoint 1 welds components and parts on printed wiring board, connects power supply, makes loudspeaker send true to nature, loud sound by the resistance that changes resistance R 3.The resistance that changes R9 then makes light emitting diode L1～L10 change with the firecrackers sound and flashes realization sound, phototiming at random.Put the joint light-passing plastic pipe similar to traditional firecrackers length for respectively L1～L10, color can be varied again, by connecting lead these plastic tubes is concatenated into the firecrackers shape arbitrarily.At last wiring board, battery, light emitting diode are fitted together, form the portable electronic firecrackers.
Claims (3)
1, a kind of electronic toy that can simulate traditional fireworks sound, light effect is characterized in that it produces circuit, battery, acousto-optic synchronization control circuit by illuminator, firecrackers sound and forms.
2, it is characterized in that according to the electronic firecracker of claim 1 defined described illuminator by light emitting diode be enclosed within diode light-passing plastic pipe on one's body and form, is concatenated into the firecrackers shape by connecting lead arbitrarily with illuminator.
3, it is characterized in that according to the electronic firecracker of claim 1 defined described acousto-optic synchronization control circuit is made up of 555 time base circuits, sound Acquisition Circuit and counting/decoding circuit.
