PROBLEM TO BE SOLVED: To support the generation of natural reverberation effect which does not depend on a listening location without using a large-scale speaker system.SOLUTION: A reverberation support device 1 includes: a sound emitting member 2 having a cavity in the inside and also having a concave or convex diffusing part 4 in at least a part of the surface; and a vibrator 3 for vibrating the sound emitting member based on a sound signal to be inputted. In the sound emitting member 2, the number of diffusing parts 4 per unit area may be different and a plurality of vibrators 3 may be provided.SELECTED DRAWING: Figure 1 【課題】大規模なスピーカーシステムを用いることなく、聴取場所によらない自然な残響効果の生成を支援する。【解決手段】残響支援装置１は、内部に空洞を有し、表面の少なくとも一部に凹状または凸状の拡散部４を有する放音部材２と、入力される音響信号に基づき前記放音部材を加振する加振器３とを備える。また、前記放音部材２において、単位面積あたりの前記拡散部４の数が異なってもよいし、前記加振器３を複数備えてもよい。【選択図】図１
