PURPOSE:To obtain the high-quality speaker stable and strong in the bonding, by performing the bonding to the support of the vibration system component with heating and pressing with the hot melting type adhesives in sheet or web shape in a short time. CONSTITUTION:In the magnetic circuit 1 consisting of the plate 3 having the center pole 2, ring shape magnet 4, and upper frame 5, the frame 6 is coupled. At the circumferential edge of the frame 6 has the edge 9 of the vibration plate 8 via the hot melting type adhesives 7 of sheet or web shape, and the adhesives 7 is heated and molten with the heating and pressure tools 10 and 11 to bond the edge 9 to the frame 6. |
