Abstract
A sound reproduction device includes a superdirective speaker having a first surface, and an attachment part having a second surface opposed to the first surface. The first surface has a convex face, and the second surface has a concave face which can come into contact with the convex face. A curvature of the convex face is set larger than that of the concave face. A direction of emitting a sound wave of the superdirective speaker can be adjusted by making the convex face move along the concave face.
