Abstract

PURPOSE:To simultaneously bond frame and damper by mounting a holder which is mounted with a voice coil bobbin into the specified position by means of a positioning pin then drawing out the positioning pin. CONSTITUTION:First, the end part 11 of a pin 10 is engaged to the recess 7a of a center pole piece 6a to position a pin 11 and piece 6a and in this state the engaging part 14 of the holder 12 is engaged to the upper part of the piece 6a to maintain the positioned position. After this, the pin 10 is drawn out throught the through-hole 13 of the holder 12 and is used for another voice coil bobbin to make preparation for the next assembling work. This enables the voice coil bobbin, frame and damper to be simultaneously bonded and perform the improved performance of assembling work and reduced production cost.
