1. A damper, comprising:
a first connecting part having a first side configured to cooperatively connect to a voice coil of a sound-producing device;
a first planar elastic part formed by first end of the first connecting part being bent and extending in an S shape toward a second side of the first connecting part, the first planar elastic part and the first connecting part provided in the same plane; and
a second connecting part connected to a second end of the first planar elastic part distal to the first connecting part, and configured to be fixedly connected to the sound-producing device;
wherein the damper is a line structure formed by integral winding,
wherein the second end of the first planar elastic part is bent into a hook structure to form the second connecting part.
