Abstract
PURPOSE:To achieve ease of assembling, high positioning accuracy and uniform quality, by fixing outside diaphragm plate piece among diaphragm plate pieces split into two concentrically and bonding the inside diaphragm plate piece. CONSTITUTION:The voice coil bobbin 2 is inserted to the holding tool 13 of cylindrical shape inserted to the positioning pin 12, and it is inserted to the magnetic circuit assembly B for the alignment of the bobbin 2. Next, the alignment pin 12 is detached from the holding tool 13 and the damper 6 is inserted to the bobbin 2 and bonded to the bobbin 2 and the frame 10. The diaphragm plate of honey- comb construction is split into two concentrically, and the drive cone 4 and the edge 5 bonded in advance to the outside diaphragm piece 19 is respectively bonded to the bobbin 2 and the frame 10, and the outside diaphragm plate piece 19 is bonded to the bobbin 2. Further, the holding tool 13 is picked up and the inside diaphragm plate piece 21 is inserted to the upper end opening of the bobbin 2 and bonded.
