Here, in the internal working part 30, a vinyl chloride resin is mixed with cellulose fine powder particles obtained by subjecting a coarsely pulverized material of wood to a pulverization treatment combined with a pulverization treatment and a polishing treatment, It is formed by extrusion molding.

As the resin contained in the mixed material, for example, PP, hard or soft polyvinyl chloride resin (PV
C), foamed vinyl chloride resin, polyethylene terephthalate resin (PET), polystyrene resin (PC), polyethylene resin, phenol resin, urethane resin, ABS resin and the like.

The raw material for the cellulose fine powder is
Although it is basically wood, in addition to wood, bacas, rice straw, pulp and the like may be used as raw materials. The type of tree used for wood is not particularly limited, and various types of trees can be used without being limited to conifers and broad-leaved trees. Also,
From the viewpoint of the quality of the wood-like resin, it is preferable that the cellulose-based fine powder particles be made of wood of the same type of tree or a tree of a similar type as a raw material so that the quality is homogenized.

The cellulosic fine particles have a particle shape as described above. The term "particle shape" as used herein means that when a plant such as wood is crushed into fine particles, In the fine powder, while the fibers are in a fluffy state,
For example, by crushing fine powder particles with a ball mill or the like, fluffy fibers are cut or pressed against the fine powder side, so that the fibers are not fluffed.

Also, without grinding with a ball mill or the like,
It is also possible to use cellulosic fine particles (wood flour) that have been subjected only to a crushing treatment.

The average particle size of the cellulosic fine particles is preferably, for example, about 1 μm to 100 μm. The resin, for example, vinyl chloride resin,
Foamed vinyl chloride resin, polyethylene resin, polypropylene resin, urethane resin, polyurethane resin, ABS resin, AS resin, EVA resin, methacrylic resin, cellulose acetate, polycarbonate, polyamide, polyacetal, polysulfone, polyethylene terephthalate, polybutylene terephthalate, polystyrene resin,
Modified polyphenylene oxide or the like can be used.

The above-mentioned resin is basically the above-mentioned thermoplastic resin, but a thermosetting resin such as phenol resin, urea resin, melamine resin, epoxy resin, polyester resin, diallyl phthalate resin is used. It may be used.

Further, fixed particles may be formed on the outer peripheral surface of the cellulosic fine particles by fixing surface particles having a smaller diameter and harder than the fine particles. Then, a resin and a pigment may be mixed with the fixed particles and melted, and thereafter or simultaneously with melting, a desired shape may be formed to produce a woody product. According to such a configuration, at the time of molding, even if heat is applied to the cellulosic fine particles, the fine particles are charred because the surface particles having a smaller diameter and harder than the fine particles protect the fine particles. It can prevent discoloration to brown or black.

Furthermore, when a wood-like product is formed using the fixed particles, it is more difficult to absorb water than ordinary wood materials, and maintenance can be facilitated. That is, it is possible to provide a wood-like product that can have a wood grain pattern in appearance and can form the same appearance as a wooden product, but is much more water resistant than a wooden product.

The surface grains may be smaller in diameter and harder than the cellulosic fine powder grains, and examples thereof include inorganic particles, pigment particles, conductive particles, resin particles, and the like, and specifically, calcium carbonate. , Titanium oxide, lithopone, metal particles such as silver, copper and nickel, conductive metal oxide particles such as tin oxide and zinc oxide, carbon particles and the like can be used.

Here, the pigment is a colored pigment and is, for example, an inorganic pigment such as iron oxide, cadmium yellow, carbon black or the like, or an organic pigment. When pigment particles are used for the surface particles, the color of the wood-like resin can be brought close to a desired color.

Further, the opening 7 serves as an outlet for the air inside the internal fabrication component 30 and promotes a satisfactory amplitude operation of the speakers 4 and 41. Further, the partition walls 6e ... Form a plurality of hollow passages in the hollow portion 5. As a result, the sound output from the speaker 4 is propagated through the hollow path,
It is possible to enhance the acoustic effect of the sound output from the speaker 4 by resonating with the sound having a constant frequency.

Further, since the internal feature part 30 is formed by mixing fine cellulose powder particles and resin, and melting and extruding the mixed material, the internal feature having the hollow portion 5 is formed. The parts can be easily formed. Further, like the partition wall 6e or the like, a shape for accommodating the speaker 4 in the hollow portion 5 of the internally-fabricated component can be easily molded. Further, since the internal working component 30 can be molded into a desired length and size because it is molded by extrusion molding, the joint portion of the members can be suppressed to a small amount, and the sound emitted from the speakers 4 and 41 can be reduced. It is possible to prevent the unevenness of the vibration of the internal fabrication component 30 due to the amplitude.

The present invention is not limited to the above embodiment. That is, it goes without saying that appropriate changes can be made without departing from the spirit of the present invention. For example, the installation position of the speakers 4 and 41, the position and size of the opening 7, and the like can be changed as appropriate depending on the position where the internal fabrication component 30 is arranged.
