Detailed Description of the Invention This discussion Il # i, the speaker Kml assembled using the
adapter. Each time the height of cone paper is changed (the length shown by 1 at 1) by the
assembly of the conventional speaker, the size of the frame is 07 lam 2 by the assembly
according to the height of 1 paper O every time the height is changed. The page and the damper
had to be prepared in nine o. When using a high-power amplifier together, the depth under the
damper should be deeper than that of the caustic one. And if it is a strange case to prevent the
lower part of the damper from coming in contact with vibration, it was necessary to newly
prepare a frame and damper of appropriate dimensions. As described above, change the
dimension of the speaker in the length direction L-"" C "" Small B production 0 In 5 L "C-" B "(50

present invention is a speaker that uses an adapter whose purpose is to be able to assemble

freely in response to dimensional changes in the height direction without changing the frame and
the damper. Next, a practical example of the present invention will be described with reference to
the drawings. The adapter used in the present invention pc is a stepped cylinder sl shown in
FIGS. 2, 3 and 4, and a damper receiver shown in FIG. 5 has a ring 2 and a page 6 shown in FIG.
The magnetic circuit holder is color 3>. The upper peripheral wall of the stepped cylindrical
portion 1 has five pairs of vertical @ & l + & * + & I + & 4b1 + bl + bs + 114 ′ ′ as shown in
FIG. 2, FIG. 3 and FIG. 110s + litg + 11411h After the storage grooves of the same length, for
example, a, b, and eta center, 140′0 and approximately 11lIm. The damper receiver shown in
FIG. 5 is for fitting the arm & ZbI, oI of the cylinder 2 to the above-mentioned longitudinal
groove. Also, the lower shoulder wall of the stepped Fq 111 portion l is a vertical groove d □
having a lower end opened and a length gradually increased. al + 'a8 + 6a81 + 11 self + 1111 +
114tx + t *, fs + f4 are provided, and the same length 0 @ groove, for example,' l + @ s + fsFi
upper 0 @ groove is equally spaced at 120 ° around the center. The lower vertical groove is
shown in FIG. 6, FIG. The magnetic circuit support shown in the figure is a turtle for fitting the
arms iJ,. ', F' of the collar 3. Assemble the speaker using the upper P adapter (stepped cylinder s1,
damper receiver 2, magnetic collar 3) # c # i in Fig. 8. Stepped cylinder i part 1 7 Fits and
adheres to the inner end step of the leero, and 4 pages next Kin: one magnetic circuit board
receives the arms d ',.', F of the collar 3 so that the height of the plate 5 of the circuit becomes
appropriate. 'To the flute with the same length l!
Plate and bond to l + el + f and plate from above 5. Insert the plotter of the magnet 圓 I consisting
of the magnet 6 and W-tuff, and attach the lower end outer edge of the magnet 6 with the step
above the inner edge of the lower end of the collar 3 8. Bond the arms a ', b' and c 'of the Linda 2
to the appropriate flute length j of the upper part of the stepped cylinder s1, for example Ras, bs
and c, and bond them with the damper 8. Glue the corn paper 9 and backing IO and complete the
assembly. It should be noted that instead of the vertical groove 0 which is provided in the
stepped cylindrical portion 1 in the above-described practical example in a stepwise manner, a
vertical groove with a horizontal groove as shown in FIG. According to the above-mentioned
paper-making method, prepare and use an adapter (Round 1 side damper receiver is a ring,
magnetic @ dairy receiver is a collar) that fits in advance for each outer diameter of the magnetic
a path. In response to the height of the paper and the height of the damper at night, the speaker
can be assembled using the existing 7 frames and dampers effectively. 5 pages
