Abstract
The present invention discloses a speaker having a vibrating system and a flexible circuit board. The vibrating system has a lower vibrating diaphragm with a first fastening portion, a second fastening portion, and a vibrating portion having a first and a second connecting portion and a middle portion. A vertical distance between a tangent line along a vertical vibrating direction at a first end of the first connecting portion and another tangent line along the direction of the middle portion is a first distance; another vertical distance between a tangent line along the direction at the second end of the second connecting portion and another tangent line along the direction of the middle portion is a second distance. Both the first and second distance are longer than a distance of the maximum elastic deformation of the flexible circuit board. The quality of speaker can be improved.
