Problems solved by technology

[0003] However, in the prior art, elastic waves are generally made by pressing the most common paper. The elastic waves of this material are excellent in cushioning performance, high temperature resistance, fatigue resistance, moisture resistance, impact resistance and flame retardancy. All aspects are poor, unable to meet the high-quality requirements of the future market for loudspeakers

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0013] This application proposes an embodiment of a fatigue-resistant elastic wave for a loudspeaker, which at least includes a combination of phenolic resin, sandalwood bark, and ethylene-vinyl acetate copolymer.

[0014] Wherein, by weight, 100 parts of phenolic resin, 18-20 parts of sandalwood bark, and 7-8 parts of ethylene-vinyl acetate copolymer. Ethylene-vinyl acetate copolymer is used to improve the toughness of the system, so that the elastic wave has high softness and moderate damping coefficient, and has good fatigue resistance, high temperature resistance, weather resistance and flame retardancy.

[0015] In the above embodiments, the number average molecular weight of the phenolic resin is preferably 40000-42000 g / mol.

[0016] In the above embodiments, the number average...

Abstract

The invention relates to an anti-fatigue damper for a loudspeaker. The damper at least comprises a combination of a phenolic resin, wingceltis bark and ethylene-vinylacetate copolymer. According to the damper for the loudspeaker of the invention, the materials of a traditional damper are improved, and the copolymer elastomer is adopted, so that the defect of low damping coefficient of an existing damper can be eliminated; and since the wingceltis bark and the copolymer elastomer are adopted in an improved manner, the damper has excellent buffering performance, high-temperature resistance, fatigue resistance, moisture resistance, impact resistance and flame resistance, and therefore, the distortion of the loudspeaker can be further reduced.

Description

technical field [0001] The invention relates to a loudspeaker component, in particular to a fatigue-resistant elastic wave used for the loudspeaker. Background technique [0002] The elastic wave is also called a baffle or a damper, and it has a braking effect and a center maintaining effect. The outer edge of the elastic wave is glued to the pot frame, and the neck of the elastic wave is glued to the neck of the voice coil and the drum paper, which can prevent the voice coil from touching the iron sheet or magnet when moving in the magnetic gap, and also Make the voice coil and the drum paper correctly connected and keep the center, so it is also called the centering piece; the performance of the elastic wave is similar to the edge of the drum paper, which affects the bass resonance F0, and has a moderate effect on the connection of the vibration plate Elastic auxiliary function, and can control the movement direction of the vibrating plate. The elasticity (softness) of t...
