Problems solved by technology

[0003] The elastic wave materials of traditional moving coil loudspeakers are mostly cotton cloth or chemical fibers, which adopt the flat weaving method. The elastic wave materials with traditional flat weave structures, such as figure 1 As shown, the stress in the direction of warp yarn 01 and weft yarn 02 is different from the centripetal tension in other directions, so that in a certain direction, it has good ductility, but in a certain direction, it is basically inextensible, which seriously affects the elastic wave. Vibration, causing the asymmetry of the vibration

Embodiment 1

[0027] Such as figure 2 , image 3 As shown, a special elastic wave 1 for loudspeakers is a cloth structure, the cloth structure is formed by looping a plurality of warp yarns 11, and coils 12 are looped around each warp yarn. The cloth structure is circular, and a plurality of concentric rings with alternating concavities and convexities are formed on the cloth structure, and a circular mounting hole 3 is provided at the center of the cloth structure.

[0028] In this embodiment, the warp yarn is preferably made of single-strand fiber, and the material of the warp yarn is a blend of cotton and bamboo fibers. In other embodiments, the warp yarn is one or more of single-strand fiber, double-strand fiber, and multi-strand fiber; the material of the warp yarn is: cotton, bamboo fiber, bamboo charcoal fiber, polyimide chemical fiber , polymer fibers, one or more of glass fibers; not limited to this embodiment.

[0029] Wherein, a hexagonal grid-shaped mesh 13 is also provided ...

Embodiment 2

[0032] Such as Figure 5 As shown, a special elastic wave for a loudspeaker is a cloth structure, which is formed by looping and splicing a plurality of warp yarns 11, and coils 12 are looped and spliced ​​on each warp yarn.

[0033] This embodiment provides a special elastic wave for loudspeakers. Its basic structure is consistent with that of Embodiment 1, and it also adopts a warp-knitted structure. Simple.

Embodiment 3

[0035] Such as Figure 6 As shown, a special elastic wave for a loudspeaker is a cloth structure, which is formed by looping and splicing a plurality of warp yarns 11, and coils 12 are looped and spliced ​​on each warp yarn.

[0036] The special elastic wave for a speaker provided by this embodiment has a basic structure consistent with that of Embodiment 1, and also adopts a warp knitting structure. 12 coils.

[0037] As an equivalent implementation of this embodiment, the shape of the mesh 13 is circular or oval, which is not limited to this embodiment.

[0038] As a further illustration of the above embodiment, the fabric structure can also be used to make a loudspeaker suspension, and the manufacturing method and specific structure are similar to those of the elastic wave, which will not be repeated here.

Abstract

The invention provides a damper special for a loudspeaker. The damper is of a cloth structure. The cloth structure is formed by a plurality of warp yarns in a loop-back and wrapped mode. Each warp yarn is looped back and wrapped to form a coil. The warp yarns are made of one or more kinds of single-strand fibers, dual-strand fibers and multi-strand fibers. The cloth structure is circular, and a plurality of concave-convex alternate concentric circular rings are formed in the cloth structure. A circular installation hole is formed in the center of the cloth structure. Compared with the prior art, the damper has the advantages that the warp knitted structure is adopted, the damper materials obtained after warp knitting are even in tensile force in the centripetal direction and good in ductility, the vibration symmetry and the vibration reliability of the loudspeaker are effectively improved, and the performance of the loudspeaker is greatly improved.

Description

technical field [0001] The invention relates to the technical field of audio components, in particular to a special elastic wave structure for loudspeakers with good ductility. Background technique [0002] Spring wave and edge suspension are two important suspension systems for dynamic speakers. A good elastic wave can effectively improve the reliability, compliance and vibration symmetry of the speaker, and can effectively reduce the distortion of the speaker, which is very important to the sound quality and performance of the speaker. [0003] The elastic wave materials of traditional moving coil loudspeakers are mostly cotton cloth or chemical fibers, which adopt the flat weaving method. The elastic wave materials with traditional flat weave structures, such as figure 1 As shown, the stress in the direction of warp yarn 01 and weft yarn 02 is different from the centripetal tension in other directions, so that in a certain direction, it has good ductility, but in a certa...
