PROBLEM TO BE SOLVED: To solve such a problem of an existing multiway speaker system in that a higher frequency signal, which is out of an audible frequency range and used for reducing distortion, cannot apply via an amplifier to a speaker used for lower-and-midrange frequency sounds since a dividing network is interposed between the amplifier and the speaker. SOLUTION: By utilizing action of electromagnetic induction, a higher frequency signal used for reducing distortion can apply directly to a dynamic speaker from a voice coil or a speaker connection wire of the dynamic speaker.
