DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction
of dome speakers. It is 4 o about O o ツ to 轡. The conventional dome / speaker tweeter O, which
is a damper (previously referred to as a damper), is an elastic thin plate ** as shown by 1 in FIG.
As a result, Pobin 5 caused a roll ν 、 工 工 、 、 ジ ジ 自 体 振動 畠 畠 畠 畠 は 工 工 工 ジ ジ

above-mentioned O defect of the prior art, and makes it a contraction to provide a 9-dome sby * tweeter-O sby 宵 -am construction. That is, in the present invention, a foamed elastic body is used
as the material of the work 9 and the thickness thereof is set to support the equivalent Km bin at
two points by setting the thickness to some extent. According to the present invention, since the
foamed elastic body is used as the work, the edge of the elastic ring is large and the Q is small, so
that the width of both sides of the edge can be reduced. (Resonance) can be prevented. Also,
since the edge and the povin contact with the ti box, it is equivalently a two-point support), and
the povin 0 ml ring is prevented. In the following, an embodiment showing the present invention
as l1liK will be described. Regards, “2” is a cut-off showing the construction of the f-layer of
the present invention--a poin 3 having l istuy # 2 is a work. Supported by di 1 spy, completion ジ

material and has a certain thickness) eII as shown in FIG. Therefore, as shown in the enlarged
view of the sIl, one @ sI- and the other am each have the ability to perform the work, the ability
to perform the diver, and the equivalent to use the double work and the di. There is no possibility
that the bobbin 5's roll will occur as a result of the bo's having 5 points of 12 points supported
