In view of that a cellulosic powder of wood has an excellent physical value when used as a cabinet material, a complex material adapted for use in a speaker cabinet has been developed from synthetic resin and cellulosic powder, therefore, a speaker cabinet being compact and having excellent sound effect and productivity is provided cheaply. In the present invention, the speaker cabinet is formed by a complex material composed of a nonchlorinated synthetic resin and a cellulosic power having particle size distribution from 5 mum to 500 mum, wherein an affinity is provided between the synthetic resin and cellulosic powder by subjecting the cellulosic power to a surface treatment. |
