Abstract: A process for magnetizing multiple magnetic circuits, which relates to the technical field of electroacoustic products. The process comprises the following steps: S1, fixing an un-magnetized first magnetic circuit assembly (12) to an un-magnetized second magnetic circuit assembly (22), so as to assemble into an un-magnetized magnetic circuit assembly (32); and S2, magnetizing the un-magnetized magnetic circuit assembly (32) that is completed in the Step S1, in this step the un-magnetized first magnetic circuit assembly (12) and the un-magnetized second magnetic circuit assembly (22) are magnetized respectively by using a first magnetic circuit magnetizing coil (40) and a second magnetic circuit magnetizing coil (50), so as to complete the process for magnetizing multiple magnetic circuits. The process for magnetizing multiple magnetic circuits resolves the technical problems of a complex process and fewer types of available glue in the process for magnetizing multiple magnetic circuits in the prior art; the process for magnetizing multiple magnetic circuits has a simple working procedure, low operation difficulty, more types of available glue, and a high production efficiency.
