Abstract
The utility model discloses a miniature sounder with high power. The sounder comprises a magnetic circuit system, a basin rack for accommodation of the magnetic circuit system, a voice coil positioned in the magnetic circuit system, and a diaphragm connected with the voice coil. The diaphragm comprises a ball top portion and a ring folding portion which is derived from the ball top portion and is recessed toward the magnetic circuit system. One side of the ball top portion, which is far from the magnetic circuit system, is provided with a damper. The damper is held on the basin rack. The voice coil, the diaphragm and the damper are fixed together so that the force for supporting the voice coil is partially transferred to the damper. The hardness and the elasticity of the damper enable the supporting for the voice coil and the diaphragm to be reinforced, such that the voice coil and the diaphragm are more stable while vibrating, thereby minimizing unbalanced modal generation, and improving power and stability of a product.
