PURPOSE:To provide a method for the manufacture of the speaker in which both a repulsion magnetic circuit speaker offering miniaturization and ease of assembling and a conventional speaker manufacture line are used to easily manufacture the repulsion magnetic speakers. CONSTITUTION:A soft magnetic center plate is arranged to an opposite face of two magnets 1m, 1m magnetized in the broadwise direction and whose same poles are opposed to each other to obtain a repulsion magnetic field at an outer circumference of the center plate by the magnetic circuit and the speaker uses a voice coil arranged in the magnetic field. In the manufacture of the speaker, a fitting part of a recessed or a projection is provided to an adhesion face between the magnetized magnet 1 and the center plate and a repulsion magnetic circuit is assembled by fitting them and projections 21, 21c or a recessed part 22 corresponding to recessed parts 11, 11c or a projection 12 provided to a lower magnet 1m are provided to the speaker frame and the magnets are positioned by fitting them. |
