Specification 3 ░ 1, title of the invention
How to make an equalizer for speakers
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of
manufacturing an equalizer for a speaker. Conventionally, as the equalizer for a speaker, for
example, as shown in FIG. 1, an equalizer A1 formed in a conical shape as a single unit or, for
example, as shown in FIG. There is known an equalizer B or the like formed by combining a
plurality of equalizer pieces BIsJsBl and a pedestal B4 so as to form an annular gap
therebetween. However, when manufacturing an equalizer of a rear type horn speaker having a
structure as shown in FIG. 2, the latter is carried out by combining a plurality of equalizer pieces
BIJ * B1 of different sizes and a pedestal B, t-sequentially (overlap) However, as a matter of
course, it is necessary to provide EndPage: 1 with predetermined gaps C1sc and Ic between the
equalizer pieces Bl + n, In, and the pedestal, respectively, so that each equalizer piece B, B, B, , B.
And spacers 4. It is necessary to interpose a spacer between each of the pedestals 4 and to
position each other to prevent relative rotation of the equalizer pieces BS + B * eBj and-, and this
conventional spacer and positioning Referring to FIG. 3, the protrusion formed in advance at a
predetermined position on the outer conical surface of the equalizer island is fitted to the
concave portion E formed in advance at the predetermined position on the inner conical surface
to the equalizer piece. @ Make a projection as a spacer to position the equalizer one bird and the
horse, and in the same way, position the equalizer one and four and the equalizer one bird and
the pedestal 4 in the same manner. A friend who goes by the whole positioning. However, such a
conventional manufacturing method is each equalizer piece A. Not only is the construction of the
horse, 4 and the pedestal 4 very complex, but also it is extremely difficult to make last, yet each
equalizer piece%,%, spherical surface '1 *' 2 which can be said to be the life of the equalizer at the

bottom of Bs As a result of pre-forming * '%, it was very difficult to combine nine' 1m'l * p's
opposite to these diaphragms so as to be flush with each other with high accuracy. This invention
was made in view of the above-mentioned circumstances, and the point made into the purpose is
the equalizer for speakers which the structure of each equalizer piece is simple, can be combined
easily, and can improve the spherical surface one precision of each equalizer piece. It is an
attempt to provide a manufacturing method of In order to achieve this object, the present
invention forms flanges at the bottom of each equalizer piece in advance, and makes the adjacent
flanges of these equalizer pieces intimately fit with each other and then combine them, A desired
equalizer is obtained by pressing a bin into at least one set of holes formed in the equalizer
pieces, and then removing the flange portions of the equalizer pieces in a spherical shape.
Hereinafter, one embodiment of the present invention will be described in detail with reference
to FIGS. 4 to 7. In this embodiment, first, for example, a pedestal lO and three equalizer pieces
11.12 as shown in FIG. 4 and FIG. 5 are prepared. That is, the pedestal 101 d is formed of a
hollow body having a cylindrical outer shape and a circular conical shape. The outer equalizer
piece 11 has an outer shape smaller by a predetermined amount than the circular shape of the
pedestal lO, a conical shape which is smaller than the circular shape of the pedestal 10, and the
inner shape is also the bottom of the hollow body 15 having a conical shape. Is formed by
integrally forming an annular 7-lane $ 16. Further, the flange portion 16 is formed with a recess
18 having a circular cross section. The middle equalizer piece 12 has a conical shape whose
outer shape is smaller than the circular shape of the outer equalizer piece 11 by a predetermined
amount and which is smaller than the circular shape of the outer equalizer piece 11 in the same
manner. An annular flange portion 20 slightly smaller than the inner diameter of the concave
portion 18 is integrally formed. Moreover, the recessed part n of cross-sectional circular shape is
formed in the said flange part. The inner equalizer piece 13C, the outer diameter of the conical
body n smaller than the inner shape of the middle equalizer piece 12 by a predetermined amount
than the inner shape of the middle equalizer piece 12, the outer diameter is smaller than the
inner diameter of the recess n of the middle equalizer piece 12 A slightly smaller annular flange
portion ? is integrally formed. Next, a description will be given of the case where the equalizer i
/ ?; p... Is constructed using the pedestal lO of the above structure and the three equalizer
sections 11.12.13. First, as shown in FIG. 5, the hollow piece 15 of the outer equalizer piece 11
with respect to the pedestal lO is inserted into the pedestal lO and the flange portion 16 is
brought into contact with one end face of the pedestal lO. Of the outer equalizer piece 11 are
inserted into the hollow piece 19t of the outer equalizer piece 11 into the outer equalizer piece
11 and the flange portion of the outer equalizer piece 11 is Coaxial EndPage: fitted in the recess
18 and arranged coaxially, and further insert the equalizer piece 13 inside the middle equalizer
piece 12 into the cone 23 / the middle equalizer piece 12 and its seven ranks The portion U is
fitted coaxially with the recess 22 of the middle equalizer piece 12. Next, in this manner, it is
temporarily fixed in such a manner that it is arranged in advance, and as shown in FIG. 5 and FIG.
In each of the three places the holes 14.17.21.25 are freed, and then each set of holes 14.1? ,

21.25, respectively, by pressing the bin grave, thereby the receiving table lO and the three
equalizer pieces 11, 12 and 13'i are fixed.
Next, one end side of the pedestal lO and the seven rungs @ 1g, 20.24 of the three equalizer
pieces 11.12.13 are cut and removed to the imaginary line position shown by Y in FIG. At the
bottom of each equalizer piece 11 ░ 12.13, a spherical surface which can be said to be the life of
the equalizer is formed respectively, and on this cut and removed surface, the pedestal 10 and
the outer equalizer piece 11. An annular space 27.2 g formed respectively by the outer equalizer
piece 11 and the middle equalizer piece 12 and the middle equalizer piece 12 and the inner
equalizer piece 13. Four are revealed respectively. Finally, the desired equalizer (9) of the
structure as shown in FIG. 7 can be obtained. In the above embodiment, after assembling the
receiving table and each equalizer piece in advance, the case of forming a hole for inserting a bin[[is described, but before assembling the equalizer, each equalizer piece and the receiving table A
hole may be formed in advance at a predetermined position of. As described above in detail,
according to the present invention, the projections and recesses for positioning the spacer, which
were conventionally required, are not required, so that the structure of each equalizer piece is
simplified, and the combination thereof is extremely easy. Can be made, the manufacturing and
combination work can be improved, and the equalizer pieces can be integrated by press-fitting
pins, so that they can be firmly integrated, and in this state, each can be integrated. Since 7 rank
parts of the equalizer pieces are removed in a spherical shape to make an annular gap between
the equalizer pieces appear on this removed surface, the effect of being able to significantly
increase the spherical surface-mm of each equalizer piece Have.
