DETAILED DESCRIPTION OF THE INVENTION In the present invention, a structure in which the
vicinity of the central hole is made ceramic to equalize the force applied to the voice coil, and the
recast of the reproduction sound quality of the speaker is obtained (the related art 0) In the coneshaped speaker 1, the voice coil 3 is positioned within the annular magnetic gap z, and the
damper 6 whose outer periphery is fixed 5 is adhered and supported above the bobbin number,
so that the voice coil 3 has the magnetic gap a @ W- Makes axial vibration so as not to touch, and
paste the tip of the cone-shaped diaphragm rod supported by attaching the outer ring to the
framer at the tip of the voice coil hovin 40 When installed, the driving vibration force according
to the voice radio wave lc passing over the die coil 3 is generated in the voice coil 3, and the
vibration is transmitted to the diaphragm 8 to produce one voice. . Damper 6 Damp 6 Dip in
general with 1 by warp yarn 91 cocoon 10, 7% enol resin with melamine concentration t "+ 1/8
degrees, impregnated with melamine resin, etc. and after drying, it has a round circle shape
Corgage bran 12 is thermoformed with a hot metal cap to maintain adequate compliance in the
axial direction. Then, the tip end of the bobbin 4 of the voice coil 3 of the outer cylindrical rod is
fitted into the center hole 13 of the damper 6, and both are adhered with an adhesive.
Furthermore, 111 is attached with an adhesive 14 through the tip circular hole of the coneshaped diaphragm 8 at the tip of the povin 4. [, If it is IIFi, in the magnetic air gap 2 violently
axial direction # c # i! Although the damper C and the outer periphery of the diaphragm 8
support the moving poise coil 30 motion, the damper 6 and the outer peripheral edge of the
diaphragm 8 support the above-mentioned structure, and the direction of the longitudinal and
lateral threads 911 O of the damper 6 In the other direction (diameter left direction), there is a
difference in the stretching force, and the compliance (stretching force) is smaller than the
direction of the yarns 9 and 10 and the other page O direction. Therefore, the force exerted by
the damper 6 on the voice coil 8 house bubi +% jIA n 4 is enhanced depending on the direction
on the damper 6 surface, and is repeatedly vibrated in the axial direction, so that the vibration
during longitudinal vibration of the cylinder ≦≦. The lewich coil bobbin 4 exhibiting j-moat will
be subjected to the hanging value oscillation state s ヲ ms. Then, when this abnormal vibration
shape & is transmitted to the diaphragm 8 as it is, and further the abnormal vibration of the body
8 is positive to the vibration of the bobbin number, the vibration of the spiral coil is further
complicated and vibration is generated. One voice emanating from the board 8 must be distorted
V). This device is a tannox 6 'which eliminates such a drawback, and the device according to the
embodiment shown in FIG. 111, FIG. 3 and FIG. The damper 61 has a ring-shaped tin plate 15
made of, for example, punched out vulcanized fiber pasted with an adhesive, and the tip of the
voice coil bobbin 4 is inserted into the center hole 13 'of such a damper 6'. Then, attach the
adhesive with adhesive and stick it on top, and insert the tip of the diaphragm 8 at the tip of the l
bin 4 by 4 pages and glue it on and so on. The air gap is as small as possible, and it is cylindrical
to fill in the air gap with an adhesive and to make I K entrapment.
In such a case, the difference in the compliance of the damper 6 'according to the direction IIIK
of the damper 6' suppresses the tensile force by the rigidity of the M-a flat annular rigid body 15
and the vibration mote during longitudinal vibration of the voice coil bobbin 40 Also, the rigidity
of the flat annular rigid body 15 is suppressed. Furthermore, since the number of abnormal
vibrations of the diaphragm 8 is also taken by the rigidity of the flat annular rigid wedge 15, the
rigidity of the diaphragm 8 can be increased. Therefore, the speaker 1 having the Δ damper 61
can generate extremely high quality reproduction sound without distortion. Furthermore, as
described above, this invention attaches another flat annular ring plate 15 to the conventional
corrugation damper 6 to form a rigid body portion, as well as a corrugation structure. Even if the
resin is impregnated and solidified in a thousand ring shape in the vicinity of the center hole 13
of the damper 6 'to form a rigid flat ring 13', the effect of uniform five pages can be obtained. 4

cross-sectional view showing an embodiment of this invention. Reference numeral 13 'is a central
hole, 15.15' is a one-hundred ring rigid body, and a single speaker 61-gauge full-gauge damper.
