<p>PURPOSE:To satisfactorily absorb the counter electromotive force by a voice coil and reproduce an original sound with high-fidelity, by dividing the winding of an iron core of the network into two and drawing it, when only each frequency band signal is provided to the unit of each speaker. CONSTITUTION:An iron core coil 1 of the dividing network for providing only each frequency band signal to each unit of the multiple way speaker is divided into two, its intermediate part is cut and drawn out, and it is connected to the voice coil of the speaker 2. The capacitor 3 is connected to the primary side or the secondary side of this iron core coil 1. and when a current has been made to flow into the voice coil of the speaker 2, the damping force is increased so that the iron core coil 1 can execute the push-pull operation to the speaker 2, in order to obtain an effectively damping, clear and high-fidelity tone quality to the original sound.</p> |
