    摘要: A spider of loudspeaker having a base material in the form of a plain-woven fabric of warps and wefts each of which constituted by fibers of an inorganic material. The warps and wefts are coated with a thermosetting resin which in turn is coated with a thermoplastic resin. The spider thus formed is less liable to absorb the ambient moisture and, therefore, is free from distortion.
