Abstract
Disclosed are a damper and a sound-producing device. The damper includes a first connecting part, a planar elastic part and a second connecting part. One side of the first connecting part is configured to cooperatively connect to a voice coil of the sound-producing device; an end of the first connecting part is bent and extends in an S shape toward the other side of the first connecting part to form the planar elastic part, the planar elastic part and the first connecting part being in the same plane; the second connecting part is connected to one end of the planar elastic part away from the first connecting part, and the second connecting part is configured to be fixedly connected in the sound-producing device; and the damper is a line-like structure formed by integral winding.
