Abstract

PURPOSE:To make an acoustic characteristic superior and produce a speaker cabinet cheaply, by arranging a smoothly planed board on the strengthened water-proof plaster board which is formed by sticking plate-shaped materials to both faces of a burnt plaster where a strengthening agent and waterproofing agent are mixed. CONSTITUTION:A strengthened waterproof plaster board is constituted by burnt plaster 1, where a strengthening agent consisting of an organic mixing compound, a glass fiber, vinyl acetate and/or asbestos and waterproofing agent consisting of paraffin-system emulsion are mixed, and plate-shaped materials 2 such as cardboards stuck to both sides of burnt plaster 1. Smoothly planed board 3 is provided on this board. As the result, the board has a characteristic of a large internal loss and a small Q value. Therefore, the acoustic characteristic can be improved, and specially, reduction of higher harmonic distortion can be achieved. Then, stiffness can be high by mixing the strengthener, so that a superior acoustic characteristic can be obtained.
