Curved Panel for Acoustical Shell, Method of Manufacturing the Same, and Acoustical Shell Using the Same

摘要

The present invention provides an acoustical shell for stage sets which is light and easily handled, which has no deformation of a curved surface for a long-period installation, in which a surface to reflect sound is broad and it is possible to prevent a resonance phenomenon due to a cavity, thereby providing an excellent efficiency of reflecting the sound, without eliminating even any small sound. A method of manufacturing the acoustical shell according to the present invention comprises making a laminate board by bonding a melamine pasteboard and 2 to 4 sheets of plywood or MDF using adhesives, securing the laminate board into a wood winding machine made in a curved surface shape and applying a high frequency heat-treatment such that a bending is fixed to form a curved shape, making a upper board and a lower board using the curved board, adhesively inserting a plastic board attached framing members for edging between the upper and lower boards to be pressed for integrating, thereby manufacturing a curved panel. Then, the upper and lower ends and the right and left side ends of the curved panel are overlaid with aluminum profiles, thereby completing the acoustical shell.
