Claim Text:
1. A weaving method for manufacturing a damper of a loudspeaker, comprising the steps of: a preparation step: providing a plurality of traditional warps and a plurality of conductive warps to extend in a vertical direction; and a weaving step: providing a plurality of wefts to extend in a horizontal direction transversely crossing the vertical direction in such a manner that each of the wefts passes alternately over and under each of the plurality of traditional warps and each of the plurality of conductive warps in order to form the damper; wherein after the weaving step, the damper undergoes an immersion step, a drying step, a formation step and a cutting-off step to shape the damper in a disc-shaped profile with a circular inner periphery defining a central hole, a circular outer periphery and a plurality of annular concentric corrugated portions extending outwardly and radially from the inner periphery, each of the corrugated portions having an apex and a valley defined between an adjacent pair of the corrugated portions, inner ends of the conductive warps extending inwardly from the circular inner periphery for connecting with a voice coil and outer ends of the conductive warps extending outwardly from the outer periphery for connecting with a diaphragm.
