Abstract
A loudspeaker diaphragm () comprising a woven fiber body supports damping material (), for example PVA polymer, on a rearward-facing surface (). The woven fiber body may be formed of lengths () non-metallic fiber material (for example glass fiber) coating with a thin metal coating (). The mass of the layer of damping material () may be significantly greater than the mass of the woven fiber body. An attractive sparkly looking loudspeaker diaphragm () may thus be provided which damps undesirable vibration while providing a flatter frequency-response curve ().
