<p>A method for producing the repulsion magnetic circuit of a speaker stably with high production efficiency, and a production system for use therein. Abutting position of a first magnetic circuit block fixed to a lower die (102), against a second magnetic circuit block fixed to an upper die (105) is detected by detecting the load current of a servo motor (103). The pressing time for bonding is set by the number of pulses of an encoder connected directly with the servo motor (103).</p> |
