Abstract
A reinforced speaker damper includes a ring-shaped damper body made of woven fabric in the form of a mesh and press-molded to form a wavy cross-section having alternating ridges and troughs. A plurality of reinforces is attached to the damper body. Each reinforce includes a woven fabric in the form of a mesh with rectangular openings extending in a direction different from that of the damper body and having a wavy cross-section for closely fitting over the wavy configuration of the damper body. Each reinforce is fixed to the damper body by for example sewing and extends between inner and outer circumferences of the ring of the damper body.
