PROBLEM TO BE SOLVED: To provide a sound source device for a horn which outputs a chord by use of a single diaphragm.SOLUTION: A sound source device comprises: a diaphragm 11; a movable iron core 12 which is connected with the diaphragm 11 through a fulcrum 121a; and a coil (a bobbin 14 and a coil 15) to which a driving signal including a first signal component that resonates with the diaphragm 11 and a second signal component of a second frequency that resonates with the movable iron core 12 of a first frequency and has a relation of chord with the first frequency is input. The fulcrum 121a is disposed at a position eccentric from a center O of the diaphragm 11, and the movable iron core 12 is constructed such that a centroid G is offset from the fulcrum 121a in an eccentric direction D1.SELECTED DRAWING: Figure 1
【課題】1つの振動板から和音を出力させるホーンの音源装置を提供する。【解決手段】振動板11と、振動板11と支点121aを介して接続された可動鉄心12と、振動板11と共振する第1信号成分と、第1周波数の可動鉄心12と共振し、且つ第1周波数と和音の関係を持つ第2周波数の第2信号成分とを含む駆動信号が入力されるコイル(ボビン14及び巻き線15)とを備える。支点121aは、振動板11の中心Oから偏心した位置に設けられ、可動鉄心12は、支点121aよりも偏心方向D1に重心Gがずれるように構成されている。【選択図】図1
