PROBLEM TO BE SOLVED: To provide a driving device of a sound reflecting board capable of changing a sound field in a large degree of freedom, and capable of easily reproducing its sound field when a desirable sound field can be set once. SOLUTION: A zigzag structure is formed by rotatably connecting a plurality of reflecting members 2, 2, etc. by alternately interposing a first connecting part and a second connecting part. The first connecting part is driven to be movable on the same straight line and individually movable in parallel on the same straight line. COPYRIGHT: (C)2008,JPO&INPIT
