Problems solved by technology

[0008] The elastic waves tested above all use cotton cloth as the basic material. Obviously, they have the following disadvantages: 1. The lateral force resistance is poor, which is prone to fatigue and cracks, resulting in sound damage when the elastic waves or hanging edges are used, and short service life; 2. Lack of elastic stretching force, poor resonance flexibility with sound waves, and poor sound quality; 3. Poor toughness and strength, and withstand high-power output sound wave pressure difference; 4. After a period of use, the elastic wave or hanging edge will warp Deformation, unevenness, poor restoring force, easy to fall off due to warping deformation when glued to the horn or loudspeaker

Embodiment 1

[0033] A kind of manufacturing method of elastic wave of the present invention, comprises the following steps,

[0034] a: the metal fiber with a mass percentage of 0.1% is mixed with the non-metallic fiber with a mass percentage of 99.9%;

[0035] b: Pull out to form an elastic line;

[0036] c: knitting the above-mentioned elastic thread into an elastic cloth;

[0037] d: The elastic cloth woven in step c is placed in a spring wave forming mold, and the elastic cloth is pressed at a temperature of 175° C., so that the elastic cloth is formed into a spring wave.

[0038] Specifically, by adding metal fibers and non-metal fibers in step a and mixing, wherein the mixed metal fibers and non-metal fibers are in the form of cotton balls, and then the mixed metal fibers and non-metal fiber materials are drawn, because Non-metallic fibers have excellent absorbency, strong adhesion with other materials, and metal fibers have strong elastic stretching force and toughness strength, s...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that a method for manufacturing elastic waves in this embodiment includes the following steps,

[0047] a: mixing metal fibers with a mass percentage of 10% and non-metallic fibers with a mass percentage of 90%; wherein, the diameter of the metal fibers is 9.5 μm;

[0048] b: Pull out to form an elastic line;

[0049] c: knitting the above-mentioned elastic thread into an elastic cloth;

[0050] d: Place the elastic cloth woven in step c in a spring wave forming mold, and press the elastic cloth at a temperature of 200° C., so that the elastic cloth is formed into a spring wave.

[0051] The elastic wave produced by the method of this embodiment has passed the fatigue resistance and elasticity test. The tensile force of the elastic wave test is set to be positive 38N and negative 38N, and the displacement is set to be positive 18mm and negative 18mm, starting from a starting point and slowly starting from point...

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 is that a method for manufacturing elastic waves in this embodiment includes the following steps,

[0054] a: mixing metal fibers with a mass percentage of 20% and non-metallic fibers with a mass percentage of 80%; wherein, the diameter of the metal fibers is 10.5 μm;

[0055] b: Pull out to form an elastic line;

[0056] c: knitting the above-mentioned elastic thread into an elastic cloth;

[0057] d: Place the elastic cloth woven in step c in a spring wave forming mold, and press the elastic cloth at a temperature of 200° C., so that the elastic cloth is formed into a spring wave.

[0058] The elastic wave produced by the method of this embodiment has passed the fatigue resistance and elasticity test. The tensile force of the elastic wave test is set to be positive 38N and negative 38N, and the displacement is set to be positive 18mm and negative 18mm, starting from a starting point and slowly starting from poin...

It has good lateral force resistance, is not prone to fatigue, is not easy to break, and has a longer service life; 2. It has good elastic stretching force and resonance compliance with sound waves. Better, good sound quality; 3. Good toughness and strength, able to withstand high-power output sound wave pressure; 4. Good flatness, strong resilience, and will not fall off when glued to speakers or speakers.

Description

technical field [0001] The invention relates to the technical field of manufacturing elastic waves and hanging edges, in particular to a method for manufacturing elastic waves or hanging edges and elastic waves or hanging edges. Background technique [0002] Damper and edge are one of the most important components in the horn or speaker structure. The damper or edge with better elasticity and toughness characteristics can provide better output of the horn and speaker. In addition to power and audio characteristics, it is also the basis for speaker and speaker manufacturers to control the quality of speakers and speakers, and can effectively extend the service life of speakers and speakers. [0003] The traditional spring wave and hanging edge use cotton cloth as the basic material, and the face is dipped in liquid synthetic resin to make the fibers of the cotton cloth absorb the synthetic resin. It is fixed and bonded at a certain position, and the synthetic resin covers th...
