ABSTRACT:
A speaker's surround to be attached to an edge of a diaphragm in a speaker system is provided, which is capable of keeping its predetermined shape while repeating elastic deformation for accommodating large amplitude vibration of the diaphragm. Further, the surround is highly durable to withstand the repeated large amplitude vibration, and which can achieve high sound pressure levels. The surround for a speaker system includes a surround piece made of a rubber mold and a base member embedded in the surround piece. The base member is obtained by soaking a cloth material made of cotton or aramid fiber with a thermosetting resin such as phenol resin, and press-formed with heat into a predetermined shape. The surround thus has enhanced its shape maintaining capability.
