In short, the receiving plate member 3 only needs to have a size, a thickness, and a shape on which the box-shaped acoustic device Y can be placed.

  FIG. 2 is an exploded perspective view before the base 1, the support rod 2 and the receiving plate member 3 are coupled to each other. For convenience of explanation, one metal base 1 and one metal support rod 2 are shown. Female screw holes 4 (4a, 4b) as connecting holes are formed in the front, rear, left and right of the central portion of the receiving plate member 3. When these four connecting holes 4 are connected by lines, a “rhombus shape” is obtained.

  In other words, when the front and rear connecting holes 4a and 4a and the left and right connecting holes 4b and 4b are connected by lines, a plus (+) shape is obtained. The line connecting the front and rear connecting holes 4a and 4a is longer than the line connecting the left and right connecting holes 4b and 4b.

  The pedestal 1 is shown with a part of the front portion cut away. Here, the structure of the pedestal 1 will be described. 1a is a bottom portion (bottom wall), 1b is a peripheral body portion (peripheral wall), and 1c is an upper portion (top wall).
