Abstract

PURPOSE:To completely prevent the fluctuation of the mounting position of a voice coil by combining the vertical positioning jig of the voice coil unit with the horizontal positioning jig of the voice coil unit to a pole piece and using. CONSTITUTION:Initially, the voice coil unit 1 is set to an annular groove 9a by reducing the diameter of the vertical positioning jig 9 and they are inserted and fitted and mounted on the pole piece 6. Then, the horizontal positioning jig 10 is fitted and inserted and mounted on the pole piece 6 while enlarging the diameter of the vertical positioning jig 9. Accordingly, the voice coil unit 1 is stored in the annular groove 9a completely with vertical movement regulat ed completely. Thereby, the vertical and horizontal positioning of the voice coil unit is correctly constantly correctly executed to attain the mass-production of a speaker unit with good in a sound quality and high in a reliability.
