Sound-producing device

A sound-producing device, comprising a vibrating diaphragm and a voice coil adapted to drive the vibrating diaphragm to vibrate;

• wherein there are provided at least two groups of dampers on the voice coil, a first group arranged at a first position proximate to the vibrating diaphragm and a second group arranged at a second position distal to the vibrating diaphragm;
• wherein the at least two groups of the dampers include at least a first damper and a second damper;
• wherein the first damper includes a first connecting part and a second connecting part, the first connecting part connected to the voice coil, and the second connecting part fixed on the sound-producing device;
• further comprising a bent planar elastic member between the first connecting part and the second connecting part and located in the same plane as the first connecting part;
• wherein the second damper includes a first fixing part and a second fixing part, the first fixing part connected to the voice coil, and the second fixing part fixed on the sound-producing device;
• further comprising a connecting arm between the first fixing part and the second fixing part, the connecting arm being in a corrugated shape,
• wherein the first damper is fixed at the first position;
• a first connecting part of the first damper is fixed by a connection bridge to a first connecting part of a second damper from the first group of dampers that is adjacent to the first damper, and
• the second damper is fixed at the second position in a segmented manner.
