DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving system
of a dynamic type 1E speaker etc. The drive system of the electrodynamic transducer is as shown
in FIG. 1 for every iKf (generally, the main magnet 1a in a ring, llJ main hole 2A% rear yoke & 2b
1 center yoke bar 2c, 3 ring magnetic gaps, etc. In the magnetic ring PJ path, in the annular
magnetic space t-r-y (IJ: '32 space 3 (this drive coil 4 is disposed via the elastic support 5), and
the IK And the force according to Fleming's left-hand rule is generated by the drive coil 4 (this is
what occurs. At this time, the magnetic phenomenon of the minor loop hysteresis 11 as shown in
FIG. 6G is generated in the magnetic circuit by the 'double gun effect of the No. 14 current
supplied to the drive coil 4, and the force generated in the drive coil 4 due to this phenomenon G.
As a means to improve such distortions, the columns may have at least one surface of the yoke
surface that forms the magnetic gap (as disclosed in Shikaki No. 51-26805 [2nd varnish 1]. A
metal coating 7 having a thickness of not less than 50 microns is also provided, actually: 1i (5256039 (as disclosed herein, at least the -h surface of the yoke surface forming the magnetic gap
is at least l). All of them are provided with insulation of isomorphous linog 8. These all change

formed is a part that requires more precision and a degree than that of 11 and is as shown in E.
(Y: another / Jll-L: those with means become cost higher. In addition to the defects, the center
support of the drive coil 4 is not good, resulting in the defect that the defect rate is improved. In
order to correct the entry point on the room, the proposed plan is to improve the space and
reduce the number of It is an object of the present invention to provide a drive system of a
dynamic-type converter which is effective. Next, the present invention will be referred to as 4, 5,
6, 7 + * J. FIG. 4 shows an embodiment of the present invention #, and an annulus is drilled in
front of the magnet 1a. The yoke plate 2a, the rear portion 0, the yoke plate 2b, the g yoke plate
2b, the center of the old city Q and the ring are magnetically combined with the magnet 1a (a
disc-like submagnet lb directed to this place, the disc-like Mllfa 5b in front Section (two
cylindrical yoke rods 2C are respectively disposed, and annular magnetism is achieved at the
outer edge portion of the cylindrical yoke rod 2C and the inner edge portion of the stamped yaw
plate 2a! U: T air space 3 is an annular magnetic air gap 31 month (this single-acting coil 4 is
installed via the bullet support 1. 1 body 5).
In addition, 9 is a screw and 11 is a frame. For example, when the signal current 13 shown in
FIG. 7 is supplied to the drive coil 4 of the power conversion type 4 converter having this kind of
structure), the drive coil 4G is driven by the left hand side of Fleming. In addition, the ring main
magnet 1a and the on-disk sub-magnet 1b are accompanied by the magnetic phenomenon of
minor loop hysteresis, respectively. Due to this magnetic phenomenon, the magnetic flux passing
through the annular main magnet 1a changes like the pulsating magnetic flux 14, and the flux
heat passing through the disk-like sub magnet 1b maintains the phase difference between the
pulsating magnetic flux 14 and the pulsating magnetic flux 15 Produce The waveform shape of
the pulsating magnetic flux 14.15 of the straw is mainly caused by the magnetic characteristics
of the annular main magnet 1a and the disk-like submagnet 1b. If the magnetization directions of
the annular main magnet 1a and the disk-like sub magnet are reversed (the magnetic
characteristics are different from each other), the composite magnetic flux 16 of these two
magnets becomes a pulsating magnetic flux, but the magnetism, r! If the same magnetic field is
used for n, the combined flux 16 of the two magnets will have almost no pulsating part and will
be a constant flux. The magnetization direction of the ring main magnet la and the disk-like
submagnet are reversed in this way, and the sweet acid magnetic flux 16 of the disk main magnet
1a and the disk-like submagnet 5 stone 1b is always constant if the same magnetic custom order
is used. As a result, the magnetic flux in the annular magnetic air gap 3 in which the drive coil 4
is positioned can be made constant and the generation of the minor loop hysteresis based on the
magnetic phenomenon can be prevented. FIG. 5 shows another embodiment of the present
invention, in which a magnetic G 4a 'main magnet 1a and an annular sub magnet 1b opposite to
each other are joined, and a yoke plate 2a1 is provided at the rear and a yoke yoke 2a1 at the
front. The center yoke bars 2C are disposed on the inner side of the center portion of the plate
2b and the yoke plate 2b by 4t each, and an annular magnetic gap is formed between the outer
edge portion of the centering rod 2C and the inner edge portion of the enlarged bored yoke plate

2a. In the annular magnetic air gap 3 of the magnetic circuit in which 3 is formed, the drive coil
4 is disposed with elastic support (v V). The @ fishing line of the 7-character-to-electric converter
of this structure operates in the same manner as in the above embodiment (FIG. 4) to prevent the
occurrence of distortion based on the magnetic phenomenon of minor loop hysteresis. Thus, the
magnetic circuit composed of the t magnet 1a1 submagnet 1b, the yoke member, and the
annular magnetic gap 3 in the magnetic ratio direction opposite to each other is annular by
selecting the magnetic characteristics of the main II fluorite 1a and the submagnet 1b. Magnetic
phenomenon G of minor loop hysteresis due to the electromagnetic action of the drive coil 4
disposed in the magnetic gap 3 can be reduced to a very low level (this structure is simple,
annular magnetic space!
It is possible to easily support the center of the first drive coil 4 without applying any special
means to the wall surface of the yoke member forming 4.3, and to prevent the gap deviation of
the drive coil 4 and the like.
