Sound box with variable comb groove structure

Abstract

The invention provides a sound box with a variable comb groove structure. The sound box comprises a bent plate assembly, a top plate, a side plate and a bottom plate, the bent plate assembly comprises a first bent plate and a second bent plate, the first bent plate and the second bent plate are each provided with a plurality of comb grooves, a disassembly and assembly block is installed at one end of the first bent plate, the side plate is provided with a disassembly and assembly groove, and the other end of the first bent plate and the two ends of the second bent plate are each provided with an assembly groove. The first bent plate and the second bent plate are arranged at two ends of the first bent plate, the second bent plate is arranged at two ends of the first bent plate, the other end of the first bent plate and two ends of the second bent plate are respectively provided with an assembling block, a front plate is detachably arranged between the side plates, and the front plate is provided with an equipment hole, so that a wood plate of a bent part of a sound box can be assembled and fixed in a sectional manner through the first bent plate, the second bent plate, the assembling blocks and the assembling grooves; each section of bent plate is bent in a small range to be assembled into a whole large curved surface, the bending degree of each section of bent plate is low, the stress borne by the bent plate due to bending is reduced, the bent plate is not prone to damage, the bent plate is more stable, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box with a variable comb slot structure. Background technique [0002] For a long time, the materials used in the speaker body have always been mainly wood and its products. Wood products have the advantages of high strength, light weight and good resonance performance. Therefore, high-grade speakers made of high-quality wood have excellent sound quality and are expensive. Although wood is an ideal natural material for speakers, wood products also have many disadvantages that are difficult to overcome. For example, wood must be made into a board and then bonded together, but the firmness of the bonding part is difficult to guarantee for a long time; wood is difficult to bend, and in order to reduce plane reflection, some high-end speakers heat and bend wood products, but this causes A lot of stress will easily cause the speaker to crack, and this problem needs to be...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that although the board can be bent through the above-mentioned comb groove structure, the stress generated by the bending of the whole board is still relatively large, and the existence of the comb groove makes the bent board thinner, which is easily affected by the stress and breaks , lower quality
