PURPOSE: A speaker and a method for manufacturing thereof is provided to suppress the eccentric of a plate and a magnet at the center of a yoke by welding the magnet and the plate which are center of the yoke. CONSTITUTION: A plate fuse protrusion(231) is formed in a lower of the plate(230) to be one body. The plate is fixed to the magnet(220) by fusing the plate fuse protrusion. The yoke fuse protrusion(211) is formed in an upper of the yoke(210) to be one body. The yoke is fixed to the magnet by fusing the yoke fuse protrusion. The yoke fuse protrusion and plate fuse protrusion are arranged in a first imaginary line(L). The yoke fuse protrusion and plate fuse protrusion are fused through one time spot welding. The first imaginary line is defined as a line which perpendicularly passes through the upper part of the plate and the lower-part of yoke. |
