Abstract
The present invention provides a micro speaker, including a frame with a containment space, and a magnetic circuit system and a vibration system contained in the containment space. The vibration system includes a first diaphragm, a circuit board, a skeleton, and a voice coil. The micro speaker further includes a welding plate structure and a balance component. The voice coil includes a lead wire electrically connected with the welding plate structure. By setting the balance component on the skeleton, the present invention can keep the weight balance at both ends of the skeleton, so as to ensure that the skeleton will not sway when the vibration system is working, so that the vibration of the skeleton is stable and the sound quality is improved.
