MOVABLE ACOUSTIC SHELL ASSEMBLY |
摘要 |
A movable acoustic shell assembly comprises a ground-supported crane and an acoustic shell mounted on the ground-supported crane. The crane is configured to move in a self-propelled and self-directed manner between a storage position and an in-use position within a performing arts venue. When the crane is in the in-use position, the sound shell substantially encloses a rear portion of a stage within the performing arts venue.
