Horn elastic wave and manufacturing method thereof

Abstract

The invention discloses a horn elastic wave and a manufacturing method thereof. The horn elastic wave comprises a fiber cloth body which is formed through weaving a plurality of line bodies. The plurality of line bodies are a single line body individually formed by a single fiber or are formed by multiple fibers through a multi-strand twist yarn mode. The fiber at least comprises a first fiber. The first fiber is made by one of cotton, a polyester fiber and an aromatic polyamide fiber or a combination of the cotton, the polyester fiber and the aromatic polyamide fiber. When the first fiber is simultaneously made by the cotton, the polyester fiber and the aromatic polyamide fiber, any material can individually account for 0-100% of whole weight of a fiber cloth body. When the first fiber does not account for 100% of the whole weight of the fiber cloth body, the fiber cloth body further comprises a second fiber and a resin solid shape layer, wherein the second fiber is made by one of rayon, tough silk, linen, acryl, a rubber and an artificial fiber or a combination of the above materials; the resin solid shape layer is sticked and combined to the fiber cloth body; and the fiber cloth body maintains a preset configuration after a molding method is used.

Description

technical field [0001] The invention relates to a vibrating plate structure for a loudspeaker, in particular to a loudspeaker elastic wave and a preparation method thereof. Background technique [0002] Damper is one of the most important components in the horn or loudspeaker structure. The damper with better elasticity and toughness properties not only provides better output power and audio characteristics of the horn or loudspeaker, but also is the Or in the manufacture of speakers or speakers, the basis of quality management, and effectively increase the service life of speakers or speakers. [0003] The traditionally used forming elastic wave is based on cotton cloth, which is dipped in liquid synthetic resin to absorb synthetic resin in the fibers of the cotton cloth. After drying and hardening, the cotton cloth absorbs the synthetic resin. The threads are fixed and bonded to each other at a certain position. At the same time, the synthetic resin covers the surface of ...

Problems solved by technology

[0004] Because the traditional forming elastic wave uses cotton cloth as the basic material, although the cotton cloth fiber has excellent characteristics of absorbing and bonding synthetic resin, its disadvantages are as follows: (1) The elastic wave made of cotton cloth has poor lateral force resistance and is easy to produce Fatigue and cracking cause damage to the sound of the elastic wave, and its service life is not long; (2) The elastic wave or the vibrating drum joint edge (Cone Edge) made of cotton cloth lacks elastic stretching force, and the resonance flexibility with the sound wave is not good. , and the sound texture is also poor; (3) The elastic wave made of cotton cloth has poor toughness and strength, and it is also poor in withstand the sound wave pressure of high-power output, so it is impossible to produce high-output shaped elastic wave

[0005] Therefore, in order to improve the lateral force resistance, elastic stretching force and toughness of the cotton cloth forming elastic wave, the improved forming elastic wave adds longitudinal and horizontal thin steel wires when weaving the cotton cloth to strengthen its lateral force resistance, elastic elastic force and toughness. Toughness and strength, adding vertical and horizontal thin steel wires to the cotton weaving, although the shortcomings of the general cotton forming elastic waves have been improved on the whole, but other shortcomings have occurred: (1) The thin steel wires in the cotton weaving are very important for elastic waves. The forming and cutting mold of the elastic wave produces great damage. The elastic wave forming and cutting mold is used to cut off the mold edge of the forming elastic wave. After repeated cutting of the thin steel wire, countless small depressions are produced. After a period of time, the cutting mold cannot cut the forming elastic wave. wave, the cutting mold must be replaced, in addition to interrupting production, resulting in a waste of time and efficiency, and increasing the cost of the mold, the manufacturing cost will also increase; (2) the elasticity and toughness of the fine steel wire are much higher than that of the cotton fiber, resulting in local The uneven force causes the interference phenomenon of sound wave resonance; (3) the thin steel wire on the inner ring side or the outer ring side of the cut-off forming elastic wave must be cut or bent to avoid contact with other metals to generate a short circuit of the current damage to the entire horn or speaker
