Abstract

PURPOSE:To fit a voice coil into the magnetic gap of a magnetic circuit without eccentricity, by positioning the voice coil for the condition of fitting into the upper layer of an upper plate by a jig when oscillation-system parts, which has the upper layer coupled to a frame and is fitted into the frame, is fitted. CONSTITUTION:A ring-shaped magnet 20 is fitted onto a plate 19 having a center pole 18, and a ring-shaped upper plate 21 divided into two, upper and lower layers is fitted onto this magnet 20, thus constituting a magnetic circuit 17. A lower layer 22 of the upper plate 21 is provided with plural guide holes, and guide projecting parts 25 which should be press-coupled to these guide holes are provided on the lower face of an upper layer 24 which is fitted onto the lower layer 22. A frame 26 is coupled to the upper face of the magnetic circuit 17, namely, the upper face of the upper layer 24 of the upper plate 21 by welding or the like.
