Generally, a speaker has a yoke 1 with a center pole 17 provided at the center of the upper surface, as shown in FIG.
, an annular magnet 2 joined to the upper surface of the yoke 1, and an annular plate 3 joined to the upper surface of the magnet 2 to form a magnetic gap between the inner peripheral surface and the outer peripheral surface of the center pole 17. A frame 4 is attached to the plate 3, and a voice coil 5, a damper 6, a diaphragm 7, a cap 8, and a gasket 9 are attached to predetermined positions using the frame 4.

Conventionally, in order to save the material as much as possible to the extent that the magnetic resistance of the yoke 1 can be ignored, and in addition, in order to reduce the leakage magnetic flux from the magnetic circuit, a part of the bottom surface of the yoke 1 is left flat, and a flat surface is left on the outer periphery. A yoke is used which is provided with a tapered surface 10 that reduces the cutting thickness.

In the installation work of the voice coil 5 and the adhesion work of the damper 6, the diaphragm 7, the cap 8, and the gasket 9, the tapered surface 10 is provided on the bottom surface of the conventional yoke 1, as described above. The workbench was unstable, so a jig was used to stably place the speaker.

Therefore, when carrying out mass production using a belt conveyor by dividing the aforementioned speaker assembly process into each task, each worker picks up the speaker from the belt conveyor, places it stably on a jig, and then assembles each speaker. After completing the work in the process, it must be returned to the belt conveyor again, causing a significant decrease in the efficiency of assembly work. Furthermore, it was extremely unstable when moving on a conveyor.

The present invention eliminates the above-mentioned drawbacks by providing a protrusion on the tapered surface whose apex is substantially coplanar with the flat surface, thereby eliminating the need for jigs in the assembly process. This provides a speaker that can be used on a flat workbench or on a flat belt conveyor.

FIGS. 2 and 3 show the main part (yoke) of an embodiment of the present invention, and show the tapered surface 10 of the yoke 1.
A plurality of protrusions (ribs) 11 are provided that extend radially. The top end surface 12 of each rib 11 has a height such that it abuts on one plane.

Therefore, the speaker using the yoke according to the present invention is stable when the bottom of the yoke is placed on a flat surface.
Each assembly operation can be performed on a flat workbench or a flat conveyor belt, eliminating the need for conventional jigs.

Further, since the width of the rib 11 is sufficiently narrow to achieve the object of the present invention, it is also possible to save materials and reduce leakage magnetic flux.

4 and 5 show the main part (yoke) of another embodiment of the present invention. In this embodiment, a plurality of concentric protrusions are formed so that the top end 13 abuts on one plane. A rib 14 is formed on the tapered surface of the yoke 1. 6 and 7 show the main part (yoke) of still another embodiment of the present invention, and this embodiment has a structure in which the top end 15 is in contact with the tapered surface 10 of the yoke 1 in one plane. A plurality of protrusions (ribs) 16 are provided. Incidentally, the yoke according to the present invention having the above shape can be easily manufactured by a cold forging method or a metal powder sintering method.
