OSCILLATOR MOUNTING STRUCTURE

To provide an oscillator mounting structure capable of propagating vibration to the ear cartilage with good propagation efficiency.SOLUTION: An elastic member 22 made of an elastic material is placed between a housing 21 of a listening device and an oscillator 20. The oscillator 20 is placed at a position where its lower surface faces the ear cartilage when the listening device is worn on the ear. The first mechanical impedance of the elastic member 22 between the oscillator 20 and the housing 21 is set to be smaller than twice the second mechanical impedance of the ear cartilage as viewed from the oscillator 20.SELECTED DRAWING: Figure 5 【課題】良好な伝搬効率で耳軟骨に振動を伝搬させることが可能な振動子の取付構造を提供する。【解決手段】聴取機器の筐体２１と振動子２０との間には、弾性材料から形成された弾性部材２２が配置され、振動子２０は聴取機器を耳に装着した状態でその下面が耳軟骨に対向する位置に配置され、振動子２０と筐体２１との間における弾性部材２２の第１機械インピーダンスが振動子２０から見た耳軟骨の第２機械インピーダンスの２倍よりも小さく設定される。【選択図】図５
