Summary:In order to improve acoustic insulation properties and the like while ensuring sound perception by means of bone conduction, an ear plug (10) includes: an actuator (130) which converts an acoustic signal into vibrations; and a porous resilient body (120) which can be attached to and detached from the actuator (130) and which is to be inserted into the external ear canal with the actuator (130) attached thereto. Afin d'améliorer les propriétés d'isolation acoustique et similaires tout en assurant une perception sonore au moyen d'une conduction osseuse, l'invention concerne une fiche d'écouteur (10) comprenant : un actionneur (130) qui convertit un signal acoustique en vibrations ; et un corps élastique poreux (120) qui peut être attaché et détaché de l'actionneur (130) et qui doit être inséré dans le conduit auditif externe, l'actionneur (130) étant attaché à celui-ci. 骨伝導による音の知覚を確保しながら、遮音性の向上等を図るために、耳栓（１０）は、音響信号を振動に変換するアクチュエーター（１３０）と、前記アクチュエーター（１３０）に着脱自在であって、当該アクチュエーター（１３０）が着装された状態で外耳道に挿入されるための多孔質の弾性体（１２０）とを含む。
