Focusing on cellulose-based powder materials, such as wood, which has excellent physical property values as a speaker cabinet material, a material suitable for a speaker cabinet has been developed from a mixed material of synthetic resin and cellulose-based powder material. A speaker cabinet made of a mixed material of a non-chlorine synthetic resin and a cellulose-based powder having a particle size distribution of 5 µm to 500 µm. In order to impart affinity between the synthetic resin and the cellulose-based powder, the cellulose-based powder is subjected to surface treatment. This speaker cabinet is compact and has excellent acoustic performance, and also has excellent productivity and can be provided at a low cost on the market. |
