The invention relates to a metal flat wire-woven loudspeaker damper fabric and a manufacturing method thereof. The method includes the following steps of: preparation step: a plurality of warp yarns and a plurality of metal flat wires are arranged at intervals in a first direction, and the linear direction of the warp yarns and the metal flat wires is perpendicular to the first direction; and weaving step: a plurality of weft yarns are arranged at intervals in a second direction, one end of each weft yarn is further woven between the warp yarns and the metal flat wires along the first direction, so that the weft yarns, the warp yarns and the metal flat wires are woven into a fabric. Thus, with the loudspeaker damper fabric manufactured by using the manufacturing method adopted, fiber loosening, elasticity deterioration or aging or deformation of the fabric under long-term vibration can be prevented, and a loudspeaker can output high-quality sound. The service life of the fabric is long.
