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 case proposes a high temperature and corrosion resistant elastic wave for loudspeaker, which at least includes a combination of phenolic resin, poplar fiber and ethylene-propyne copolymer.

[0014] Among them, in parts by weight, there are 100 parts of phenolic resin, 25-26 parts of poplar wood fiber, and 4-5 parts of ethylene-propyne copolymer. Poplar fiber and ethylene-propyne copolymer are 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 sex.

[0015] In the above embodiments, the number average molecular weight of the phenolic resin is preferably 38000-40000 g / mol.

[0016] In the above embodimen...

Abstract

The invention discloses a high temperature resistant and corrosion resistant damper for a loudspeaker. The high temperature resistant and corrosion resistant damper at least comprises a combination of phenolic resin, poplar fiber and an ethylene-propylene copolymer. According to the high temperature resistant and corrosion resistant damper disclosed by the invention, the material of the traditional damper is improved, the introduced copolymer elastomer effectively overcomes the defect of low damping coefficient of the existing damper, and moreover, due to the improvement of the poplar fiber and the copolymer elastomer, the damper has excellent buffering performance, high temperature resistance, fatigue resistance, moisture resistance, impact resistance and flame retardancy, so that the distortion of the loudspeaker is further reduced.

Description

technical field [0001] The invention relates to a loudspeaker component, in particular to a high-temperature and corrosion-resistant elastic wave for a 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...
