Description

Method for preventing elastic wave deformation

The invention relates to a method for manufacturing a wave wave for a horn, in particular to a method for preventing deformation of a bullet wave.

Button, Damper is one of the most important components in the speaker or speaker structure. The elastic wave and toughness characteristics are better. In addition to providing better output power and audio characteristics of the speaker or speaker, it is also a speaker or speaker. When the speaker manufacturer manufactures the horn or speaker, the basis of quality control increases the life of the horn or speaker.

However, the conventionally used method of forming the elastic wave is mainly based on cotton cloth, and then the cotton cloth is dipped in the liquid synthetic resin to absorb the synthetic resin in the fiber of the cotton cloth, and the cotton cloth absorbing the synthetic resin will be dried and hardened. The longitudinal and transverse fiber lines of the woven cotton cloth are fixedly bonded to each other at a certain position, and the synthetic resin is covered with the surface of the cotton cloth to form a synthetic resin film which is insulated from both sides of the cotton cloth, and the cotton cloth having the synthetic resin film. Then in the forming elastic wave, the cotton cloth will first spread out. Then, the cotton cloth is heated and pressurized by a mold to form a shape of a bomb wave. Finally, the cutting step is performed, and a cutting device is used to cut off the cotton cloth to obtain an elastic wave. The appearance of the elastic wave can be set to a circular shape, an ellipse shape, a rectangular shape, or the like, and the cross section is wavy.
