[0002] The magnetic circuit is an important part of the speaker. Figure 4 The figure shows the product structure diagram of the speaker magnetic circuit. During assembly, the notch 1101 on the magnetic circuit body 11 cooperates with the positioning protrusion of the voice coil body to assemble into a finished speaker. The existing technology is manual alignment. First, the magnetic circuit is placed on the auxiliary fixture, and the notch is fixed by the auxiliary fixture. Then the voice coil body is installed in the fixture to assemble with the magnetic circuit. Obviously, the above assembly method uses manual alignment, which not only has low magnetic circuit assembly efficiency and inaccurate positioning, but also has poor consistency of the manually aligned magnetic circuit body for the existing automated assembly process, which affects the assembly quality.
