- FIG. 1A is a top view of one embodiment of a voice coil insertion jig
- FIG. 1B is a sectional view taken along the line A-0-B of FIG. 1A
- FIG. 1C is a bottom view thereof.
- the voice coil insertion jig 20 includes a base 2'0a, a hollow cylindrical insertion section 20b below the base 2'0a, a plurality of movable pieces 20c, and a central projection 20d.
- the plurality of movable pieces 20c are integrally provided at an upper portion of the base 20a with a space therebetween, and the outer periphery is formed as an arc having substantially the same circumference.
- the diameter of the upper part of the plurality of movable pieces 20c is constant, and the lower part is inclined so as to have a smaller diameter.
- the central protruding portion 20d provided apart from the movable piece 20c is formed to extend upward from the central portion of the base 20a.
- the outer peripheral portion faces the plurality of movable pieces 20c with a predetermined gap.
- the movable piece 20c is provided with a horizontal slit 20e on the outer peripheral side of the lower part.
- the movable piece 20 c is formed when the jig 20 for inserting the voice coil is inserted into the voice coil 4 and when the jig 20 for inserting the voice coil is removed from the voice coil 4. It is formed to reduce the outer diameter. Therefore, the width of the slit 20 f may be any as long as the movable piece 20 c can be tilted for this insertion / removal work (in addition, the slit width is such that the movable piece 20 c does not tilt beyond the elastic limit. It is more preferable to set it at the time of insertion and extraction work.).
- the diameter d 1 of the outer circumference of the base 20 a and the insertion portion 20 b and the diameter d 2 formed by the upper portion of the movable piece 20 c in the normal state are represented by the relationship d 2> d 1.

- the slit width represents the distance between opposing sides between the movable pieces 20c.
- the central convex portion 20d is formed to be longer than the movable piece 20c, and plays a role of a knob during work.
- the magnetic gap 1 e between the voice coil 4 and the magnetic circuit 1 is secured by the thickness of the insertion portion 20 b.
- the outer circumference of the center pole 1b of the magnetic circuit 1 and the inner circumference of the insertion portion 20b are almost the same, so that there is only a margin enough for insertion by manual assembly.
- the distance between the outer periphery of the voice coil 4 and the voice coil 4 is ensured by the thickness of the insertion portion 20b, and the distance between the upper plate 1d and the voice coil 4 is also ensured by this.
- the movable piece 20 c of the voice coil insertion jig 20 is pushed inward to be deformed within the range of elastic deformation, and the voice coil insertion jig 20 is inserted into the voice coil 4. After inserting to the specified position, release the inward pushing force applied to the movable piece 20c. The movable piece 20 c makes elastic contact with the inside of the voice coil 4 in an attempt to restore the original position. As a result, voice coil 4 It is held by the voice coil insertion jig 20.
- the insertion portion 20b is fitted into the center pole 1b of the magnetic circuit 1 in which the frame 2 is adhesively bonded in advance, and inserted into the magnetic gap 1e.
- the damper 5 and the diaphragm 3 are bonded to the frame 2 and the coil bobbin 4b as shown in FIG. Thereafter, the insertion jig 20 is pulled out while the movable piece 20c is pushed toward the central convex portion. Finally, the dust cap 6 is bonded to the diaphragm 3.

This can be easily performed by the part 20d, and the workability can be improved.
- the insertion portion 2 Ob is not provided with the slit 13 as in the prior art, but is formed as a hollow cylindrical portion, so that deformation of the voice coil can be prevented.
- the magnetic gap 1e can be secured stably because the securing of the magnetic gap 1e depends only on the thickness of the insertion portion 20b. Therefore, the magnetic gap 1e can be narrowed, the magnetic efficiency can be improved, the output can be increased, and the reduction in the size of the magnetic circuit can reduce the speed.
