DROPLET DIFFUSION PREVENTION DEVICE

To prevent diffusion of droplets when playing a wind instrument.SOLUTION: A droplet diffusion prevention device installed to cover an open end formed at a tip of an acoustic emitting part included in a wind instrument includes: a sheet-like filter material; and an annularly shaped frame body that is removably installed at the filter material and the tip of the acoustic emitting part. The frame body is an elastic member and has a groove on its inner circumferential surface, and the groove is provided on the whole circumference of the inner circumferential surface. When the filter material and the tip of the acoustic emitting part are inserted into the groove, the frame body and the filter material are provided on the acoustic emitting part and the filter material covers the open end.SELECTED DRAWING: Figure 3 【課題】管楽器の演奏時に飛沫の拡散を防止することができる。【解決手段】管楽器が有する音響放射部の先端に形成された開口端を覆うように設けられる飛沫拡散防止装置は、シート状の濾材と、濾材及び音響放射部の先端に着脱可能に設けられる円環形状の枠体と、を備える。枠体は、弾性部材であり、内周面に溝が設けられており、溝は、内周面の全周にわたって設けられている。溝に濾材及び音響放射部の先端が挿入されると、枠体及び濾材が音響放射部に設けられ、かつ、濾材が開口端を覆う。【選択図】図３
