ることを特徴としたスピーカの構造。[Scope of Claim for Utility Model Registration] A vibration system suspension is disposed inside a magnetic circuit, and the outer periphery of the suspension is located between the outer periphery of the guide ring member fitted to the yoke pole portion and the magnetic circuit component. In the speaker in which the yoke pole part and the guide ring member are sandwiched, a plurality of convex parts are provided on either the outer periphery of the yoke pole part or the inner periphery of the guide ring member in a frequency-divided manner, and the yoke pole part and the guide are connected by the convex parts. A speaker structure characterized in that the cavity volume is set to be increased or decreased by the area of a gap formed between the ring member and the ring member.
