PURPOSE:To prohibit a magnetic linkage between magnets by positioning plural magnets by regulating their axial directions in a specific manner. CONSTITUTION:Coils 1 and 2 are positioned on a substrate 3 in a manner that the axis of the coil 2 coincides with the equipotential line (m) of the coil 1. By this positioning, the magnetic potential line M of the coil 2 and the said line (m) intersect orthogonally with each other. Therefore, the coils 1 and 2 are hardly linked magnetically. As a result, a compact and simple network circuit can be formed by utilizing one sort of coil bobbin for such as horizontal mounting and providing the coils close to the substrate, which may be for a multiway speaker system or others. |
