Method of manufacturing a damper for a loudspeaker

摘要

A method of manufacturing a damper of a loudspeaker includes the steps of: immersing a fiber cloth with a resinous solution containing resin and formaldehyde catching agent, wherein the resin comprises formaldehyde while the formaldehyde catching agent reduces the amount of formaldehyde in the resin; drying the immersed fiber cloth; forming the dried fiber cloth to a configuration similar to a shape of the damper; and cutting the dried fiber cloth along the shape of the damper, thereby obtaining the damper having low formaldehyde content.

1. A method for manufacturing a damper for a loudspeaker, comprising the steps of:
an immersion step: immersing a piece of fiber cloth within a resinous solution containing resin and formaldehyde catching agent in order to obtain an immersed fiber cloth, wherein the resin comprises formaldehyde while the formaldehyde catching agent reduces the amount of formaldehyde in the resin; a drying step: drying the immersed fiber cloth containing the resin for a period of time under a temperature of about 80° C.; a formation step: forming the dried fiber cloth containing the resin to a configuration similar to a shape of the damper, wherein in the formation step, the dried fiber cloth containing the resin is heat-pressed with a temperature higher than the temperature in the drying step; and a cutting-off step: cutting the dried fiber cloth along the shape of the damper, thereby obtaining the damper having low formaldehyde content.
