Paper loudspeaker box, winding equipment for paper loudspeaker box drum and method for winding paper loudspeaker box drum

Abstract

The invention discloses a winding equipment for a paper loudspeaker box drum. The paper loudspeaker box comprises a box body, a sounding element, an electric cable and a wiring terminal. The front wall board, the upper wall board, the rear wall board and the lower wall board of the box body form a square paper loudspeaker box drum in an integral structure, which is wound by wood pulp paper and common board paper, the inner wall of the square paper loudspeaker box drum is formed by winding the wood pulp paper, the outer wall of the square paper loudspeaker box drum is formed by winding the common board paper, and the outer wall is thicker than the inner wall. The winding equipment for the paper loudspeaker box drum comprises a winding mould arranged on a power shaft and a compression roller arranged below the winding mould, wherein a left and a right end shafts of the compression roller are respectively arranged on a left and a right compression devices in the same structure in a rotatable manner. In the method, the square paper loudspeaker box drum of the paper loudspeaker box is wound by the winding equipment for the paper loudspeaker box drum. Compared with the prior art, the paper loudspeaker box has excellent acoustic quality, is low in cost and easy to process, does not contain harmful substances and can be recovered for making new paper. The comprehensive indicator of the loudspeaker box is improved by 30%.

Description

technical field [0001] The invention relates to a sound box, in particular to a paper sound box, winding equipment for its box barrel and a method for winding the box barrel. Background technique [0002] As we all know, the material of the speaker cabinet has a great influence on the sound quality of the speaker. At present, the cabinet materials of speakers mainly include plywood, particle board, fiberboard, original wood board and so on. Among them, the cost of plywood and particle board cabinets is relatively low, but the sound quality is not good; the fiberboard cabinet is hard but not flexible, the sound quality is not perfect, and the cost is high, and the production process is more complicated; the original wood board cabinet consumes a lot of money. The cost of renewable resources is greatly increased, and the rigidity is not good, and the surface paint layer contains harmful chemicals, which is not environmentally friendly; there are also paper materials used to m...

AI Technical Summary

Problems solved by technology

Among them, the cost of plywood and particle board cabinets is relatively low, but the sound quality is not good; although the fiberboard cabinet has high hardness, its elasticity is not good, the sound quality is not perfect, and the cost is high, and the production process is relatively complicated; the original wood board cabinet consumes a lot of money. The cost of renewable resources is greatly increased, and the rigidity is not good, and the surface paint layer contains harmful chemicals, which is not environmentally friendly; there are also paper materials used to make speaker boxes, but due to the uneven density of the box, or the box is made of flat panels There are too many splicing seams, or the box wall of the box is made of a kind of paper, and its sound quality is still defective
