Abstract
Flat knitted tinsel wires (2h) are sewn on a base cloth (B) of a conductive suspension (1) with a sewing thread (3) and the ends (2ha, 2hb) of the flat knitted tinsel wires extend outward from the conductive suspension (1). In this suspension device, a work load of peeling off the flat knitted tinsel wire ends (2ha and 2hb) from the base cloth (B) is reduced and associated problems are solved. The flat knitted tinsel wires (2h) are sewn on the base cloth (B), with the flat knitted tinsel wire ends (2ha, 2hb) being positioned at base close holes (B1), and thermally pressed and trimmed together with the base cloth (B).

A method of fabricating a loudspeaker suspension device having a suspension (1) and voice coil connection conductors (2h) mounted on a surface of the suspension (1), comprising:
- mounting the planar voice coil connection conductor line along a surface of a planar base member strip;
- pressure molding the base member strip (B) mounted by the voice coil connection conductor line into a predetermined shape, and trimming the pressure-molded base member strip into a suspension device, characterized in that;
- the base member strip on which the voice coil connection conductor line is to be mounted includes cut portions (B1) at positions corresponding to signal input ends (2ha, 2hb) of voice coil connection conductors for the suspension device;
- the cut portions are bridged with the planar voice coil connection conductor line mounted on the base member strip, and
- the signal input end (2ha, 2hb) of the voice coil connection conductor is left as a projection at the cut portion of the base member for the trimmed suspension device.
