Abstract

PURPOSE:To realize a high-productivity and low fraction defective manufacturing method for the dome-type speaker by dividing previously and concentrically the upper plate into two parts. CONSTITUTION:The ring-shaped magnet 12 is bonded onto plate 11 containing center pole 10, and outer circumference part 13 of the upper plate which is divided concentrically into two parts is positioned and then bonded to pole 10 via tool 14. Then voice coil 16 is connected to dome-type diaphragm 15 with projection part 17 touching diaphragm 15 plus coil 16 fitted inside the device. Tool 20, having projection bar 19 to give positioning to the inner diameter of inner circumference part 18 of the upper plate, is used to give adhesion outside the device between part 18 and the fringe area of diaphragm 15. After this, part 13 is adhered to part 18 of the upper plate to complete a dome-type speaker.
