description A micro-speaker includes a frame body, a diaphragm arranged on the frame body, a magnetic structure and a voice coil arranged in the frame body. An upper end of the voice coil is fixed to the diaphragm. The magnetic structure is arranged under the voice coil. A voice coil balancing system is provided in the frame body, which is composed of two symmetrically arranged dampers and two symmetrically arranged elastic members, which are paired and respectively arranged at mounting portions under two opposite ends of a long axis of the frame body and fixed with glue. Each of the two dampers is made of a flexible circuit board, including a first end, a second end and a cantilever connecting the first end and the second end. A ratio of a length L of the cantilever to a distribution distance D of the cantilever is between 2-15.
