A double-sound sound and light simulation electric firecracker

Abstract

The invention discloses a double-sound acousto-optic simulation electric firecracker, which comprises a circuit and a resonator for producing bright and explosive sounds; the explosive sound produced by the circuit for producing bright and explosive sounds is produced under the action of the resonator The high-pitched explosive sound and the low-pitched explosive sound, the circuit for generating light and explosive sound generates low-pitched explosive sound and high-pitched explosive sound successively through the resonator under the action of the control circuit. In the present invention, the blasting head mechanism utilizes the basic structure of the horn-type high-pitched horn, so that the airflow and sound generated by the electric spark can be transmitted, reflected, and resonated through the cavity of the high-pitched horn, and the multivibrous resonance with the resonator as a whole , to produce the sound effect of the first sound of "bang" similar to the second kick; the second blasting mechanism is equipped with a high-pitched blasting glass tube and an echo hole, and the airflow and sound generated by the electric spark are transformed by the second blasting mechanism to produce a "pop" ” sound, so as to realize the sound and light effect of electric firecrackers with two kicks.

Description

technical field [0001] The invention relates to the technical field of acousto-optic simulation electric firecrackers, in particular to a dual-sound acousto-optic simulation electric firecracker. Background technique [0002] Double-sounding firecrackers, also known as Erqijiao, are a traditional folk product, often used in festivals, weddings, memorials, and many other occasions. There are two layers of gunpowder in the paper tube of double-sounding firecrackers. The function of the lower layer of gunpowder is to send the firecrackers into the sky. The first sound of the second kick is that the gunpowder at the bottom is under a relatively low pressure, and the fire-breathing recoil produces thrust. The sound of sparks is similar to small firecrackers. It is fast, crisp and bright, mainly with high-pitched components. It is difficult to simulate the first sound of two-kick firecrackers in the existing electric spark discharge explosion sound technology. Contents of the i...

Problems solved by technology

The first sound of the second kick is the explosion of the gunpowder at the bottom under a relatively low pressure, which mainly produces thrust due to the recoil of fire. The sound of sparks is similar to small firecrackers. It is fast, crisp and bright, mainly with high-pitched components. It is difficult to simulate the first sound of two-kick firecrackers in the existing electric spark discharge explosion sound technology.
