[Detailed Description of the Invention] The present invention relates to a large speaker that
measures the improvement of mass of a + mst, warmth <L, C Noka, and divides + 1 lIt. In order to
improve the luster of the speaker at one point, it is considered that seven is the most effective if
the line, the slowness and the system omtts are destroyed. Among the vibration systems of the
above, the weight of the swing S-board has an influence on the performance of the speaker IIK.
From such a thing, making the diaphragm thin and improving the efficiency of the field <1 °

described above, the present invention is intended to lighten the weight of the diaphragm and to
reduce the distortion due to the division 11 significantly and to provide a mourning speaker.
Below this invention? -Explained by the drawings of the embodiment. Reference numeral 1
denotes a field section composed of a plate of 7 plates, a pole Rt, a plate, a ring-shaped magnet 4
and an upper plate 6 of an Oka-ring-like shape. The edge between the gas cep 7 and the 4 K II
plate 80 is bonded 114 to the edge of the frame 6 by means of a Jll agent or the like. A coil
bobbin 10 on which a voice coil is wound is coupled to the center of the diaphragm 8 and an
intermediate portion of the coil bobbin 1o is supported by a damper 11 having a skin fixed to the

frame 6 and is 0 → and A dust cap 12 is attached to the upper end of the coil bobbin 1o. It is a
general speaker in the case of Kamiki, but the μ roller, which is the feature of the present
invention, is on the 11Ill board 8. $ Bage 7-This diaphragm 8 is provided centering on the center
of the lll experimental board 8 so as to intersect the non-circular corrugation, n 13111 @-, and
star-on the cone surface as it is called 纂 aSa It is troubled by Also, as Korghanen 13 as よ う

14 Ha, Corrugated Caon 1s 52m 1 lK degrades strength but 1 this 11m shallows the concave @
14 You can solve it by doing this. -Other corrugations, 71 m or, as shown in Fig. 4, butt 616 t%
WIL, even more%. This corrugene, 1s, is a fiber and a cone C as a vibration @ 8, and it is
combined with a g * tumor (it is also good that it is formed into a cylinder simply by pressing).
As described above, since the speaker of the present invention uses the diaphragms provided so
as to cross the cone 1iK non-circular corrugated 7w7t11M1 @, it is possible to give rigidity t by
this pluegene, n, 9 Therefore, it is possible to make the quality t S composition thin by thinning lll
l l l l l and to improve the quadruple as the S 4 /-] b force. Also, the stiffness which does not
generate split resonance even if the diaphragm is thin can be made one by one, and this can be
made excellent even with a low distortion life. As described above, various benefits Jt 4 are great
for practical treatment. 4、l! Brief description of 1fI @ 1- shows one embodiment of the
