Surround for speaker system and manufacturing method thereof

摘要

A speaker' s surround (1) to be attached to an edge of a diaphragm (2) 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 (2). Further, the surround (1) is highly durable to withstand the repeated large amplitude vibration, and which can achieve high sound pressure levels. The surround (1) for a speaker system includes a surround piece (1A) made of a molded rubber and a base member (1B) embedded in the surround piece (1A). The base member (1B) 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 (1) thus has enhanced its shape maintaining capability.
