DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a network of
speaker systems. The attachment method of the coil in the network of the conventional speaker
system is shown in FIG. 1 ((alpha)) (b). (?) is a plan view, (Al is a sectional view. In FIG. 1 (?) (h),
1 is a substrate, 2 and 2 are 2 coils, 3 is J 'и 1 и A and has an A / I + screw, 4 is a washer, and 5 is
a seated nut. . Although this method is good in the case of one coil, when it becomes two or more,
the distance between the coils 2 and 2 can not be reduced because of the magnetic coupling of
two coils, which requires a large substrate. There is a drawback. An object of the present
invention is to obtain a speaker system network which can miniaturize a substrate without the
influence of magnetic coupling. In order to achieve the above object, the present invention is to
attach the coil axes orthogonally to the substrate in order to eliminate the influence of the
coupling. The network of the speaker system according to the present invention will be described
below with reference to an embodiment shown in FIG. FIG. 2 ((El, (bt represents an embodiment
of the present invention). (?) shows a plan view (h) shows a cross-sectional view. In FIG. 2, 1 is a
flint substrate and is provided with a network circuit such as a low pass filter and a bypass filter,
and a first network coil 2 inserts a screw 3 into the center hole of its bobbin via a washer 4 on
this substrate 1 It is tightened with a nut 1 and attached. Further, the ninth network coil 2 is
disposed in the vicinity of the coil 2 so that the axial direction is orthogonal to the axial direction
of the coil 2 and is made of a nonmagnetic material such as central hole Kn copper of the bobbin
of the second coil 2 The stopper 6 is inserted, and the stopper 6 is bent in a U-shape, inserted
into the hole of the substrate 1 and fixed by the solder 7. In such a device, the first coil 2 and the

second coil 2 have no magnetic coupling because the axial directions of the coils are orthogonal
to each other, and the two coils can be arranged close to each other. You can make 1 smaller. As
described above, according to the present invention, since the axes of the two coils are
orthogonal to each other, there is no influence of coupling and the distance between the coils can
be reduced. Therefore, the substrate can be made smaller.
