Description

TECHNICAL FIELD The present invention relates to a speaker enclosure formed by joining wood panels such as plywood.

2. Description of the Related Art Speaker enclosures that use wood panels such as plywood are often used because they can produce good quality reproduced sound.
These loudspeaker enclosures, when joining adjacent wooden panels with a predetermined angle forming angle, are rigidly joined by providing various connection means at the end of the wooden panel or at the inner surface of the end of the wooden panel. The other wood panel is assembled so as to be a rigid body by abutting the end surface of the other wood panel and using a nail and an adhesive together.

Problems to be Solved by the Invention As described above, the conventional speaker enclosures made of wood panels are assembled by using joint nails and the like to make the wood panels as rigid as possible. And
While sufficient strength as a box can be obtained, in any joint structure, the wooden panels are facing each other, and since both panels are firmly connected immediately after each other, the panels due to vibration are not attached to each other. There is a problem that interference cannot be prevented, harmful reverberation is generated, sound quality and reproduction characteristics are deteriorated, and the advantages of the wood panel cannot be fully utilized.

Also, in the conventional joint structure in which the ends of the wood panel are faced through the joints and directly joined, the panel joint angle, that is, the corner angle formed by the adjacent panels exceeds 90 degrees. Manufacturing is difficult, and the above corner angles are
The scope of application is limited to 90 degree rectangular parallelepiped enclosures, etc., there is a drawback that it can not meet various tastes of enthusiasts, and the advantage of being able to obtain higher quality reproduction with less distortion by making the enclosure polyhedral There were problems such as not being able to do so.

The present invention solves the above problems, and its purpose is to manufacture a polyhedral enclosure such as a dodecahedron or a dodecahedron, which is expected to produce high-quality reproduced sound. The present invention provides an enclosure, particularly a speaker enclosure characterized by the joint structure of its wood panels.

Means for Solving the Problems As a means for achieving the above object, the present invention provides a method for achieving the above-mentioned object when adjacent wood panels are joined at a predetermined angle forming angle to form a speaker enclosure. The inner edges of the wooden panel end faces are arranged in a butting state, so that they are in a so-called edge-to-edge contact (line-to-face contact) state, and at the abutting, corner corner grooves that open on the outer edge side are formed between the adjacent wooden panel end faces. Then, embedded wood is inserted in the corner groove to assemble the enclosure.

Action The present invention temporarily assembles a polyhedron with the wood panels mutually abutting each other (line-to-face contact) as described above, and by forming the corners at the proper angles by this inner edge abutting, the wood panel end faces are The polyhedron speaker enclosure can be easily and properly assembled by forming a corner groove that opens outward at a portion corresponding to a corner and inserting a buried wood in the corner groove. This embedded wood is bonded to the end surface of the wooden panel with an elastic adhesive etc. to fill the groove, adjust the appearance and square out, and if necessary, apply a decorative material to the corners and the surface of the wooden panel to finish the surface. To form the enclosure.

In this speaker enclosure, the inner edges of the wooden panels are abutted against each other, and the embedded wood is not exposed on the inner peripheral surface of the speaker panel, and is closed by the inner edges of the wooden panels. Therefore, the sound effect is not disturbed due to the embedded wood on the inner peripheral surface of the speaker enclosure, and a high quality reproduced sound is provided.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a polyhedral speaker enclosure formed by implementing the present invention, for example, a regular pentagonal wood panel 1.
Fig. 2 is an external view of a regular dodecahedron speaker enclosure formed by combining the above, and Fig. 2 shows a cross-sectional view of the regular dodecahedron speaker enclosure. A sound emission port 3 is formed on the panel 1 so as to project inward. The speaker 2 and the sound emission port 3 can be installed in plural on any wood panel using a polyhedral structure.

FIGS. 3A to 3C are enlarged views showing the joint structure of the wood panel 1 with its main part.

Then, as shown in FIG. 3A, the adjacent wood panel
When joining 1,1 at a predetermined angle forming angle α to form the enclosure, the inner edges 5,5 of the end faces 4,4 of both wood panels are brought into abutment with each other. The abutting is line contact between the edges, and in this line contact state, the corner forming angle α is set to an angle according to the polyhedron, and at the same time,
A corner groove 6 is formed between the end faces 4, 4 of the adjacent wood panel.
The corner groove 6 opens on the side of the outer edges 7, 7.

The angle forming angle α is 90 degrees in the case of a rectangular parallelepiped enclosure, that is, a regular hexahedron enclosure, and is larger than 90 degrees in the case of a polyhedron having 6 or more sides. Plywood is preferably used as the wood panel 1.

The wood panels 1 and 1 are bonded to each other at the edge-to-edge contact (line contact) portion using an adhesive 8. As the adhesive 8, an adhesive having a short work time and good workability is used, which forms a hard adhesive layer such as an instant adhesive for woodworking, shows high adhesive strength even in a small adhesive area, and can perform rigid adhesion. .

Next, as shown in FIG. 3B, an adhesive having elasticity is grooved as a filling material 9 in the corner portion of the corner groove 6 formed by the edge-to-edge contact. A suitable example of the filler 9 is a hot melt adhesive, that is, a polymer compound that melts when heated and returns to a solid when cooled, such as glue. The adhesive has a high elasticity and is one of suitable materials as an elastic filler having an adhesive action. The filling material 9 exerts an elastic effect in the corners of the corner grooves 6 and the inner edges 5, 5 of adjacent wood panels,
It suppresses vibrational interference at the butt part of 5 and at the same time maintains the strength until the completion of the next embankment.

Next, as shown in FIG. 3C, an embedded tree 10 is inserted in the corner groove 6 provided with the adhesive and elastic filler 9. A wooden or synthetic resin tree bark is used as the embedded tree 10. For example, a porous synthetic resin material or the like can be used.

The embedded wood 10 is bonded to both wood panels 1, 1 integrally with the wood panel end faces 4, 4 with a soft adhesive layer 11 having elasticity interposed therebetween.

As the adhesive, for example, a vinyl acetate resin emulsion adhesive is used. This adhesive has a very strong adhesive force, is excellent in deterioration resistance, and forms a soft and impact-resistant adhesive layer 11.

After inserting the above-mentioned embedded wood, the outer surface of the embedded wood 10 is attached to both wood panels 1,1.
Cutting to match the outer surface of the corner finish (external corner finish)
Then, a decorative material 14, for example, a thin veneer (decorative board) or sheet having a wood grain pattern is put on the outer surfaces of the wood panels 1, 1 and the embedded wood 10 to hide the corners where the embedded wood 10 is interposed.

In the present invention, pentagonal, triangular, rhombic, hexagonal, etc. panels can be appropriately combined and implemented as the wood panel 1.

As described above, according to the present invention, the wooden panels forming the speaker enclosure are abutted against each other at the inner edges, so-called line-contact state, so that a temporary assembly state of the polyhedron can be formed, thereby forming the polyhedron. All angles can be corrected and corner grooves can be secured appropriately and easily, and polyhedral speaker enclosures such as regular hexahedron, dodecahedron, 26-sided, 30-sided or 32-sided can be easily and accurately assembled and manufactured. Further, it is possible to effectively enjoy the advantage that high-quality reproduced sound can be obtained by making the speaker enclosure a polyhedron.

In addition, the inner peripheral surface of the enclosure can be formed in a closed state by abutting the inner edges of the above wood panels with each other, and the embedded wood is not exposed on the inner peripheral surface of the enclosure. It is possible to provide various reproduced sounds and effectively utilize the advantages of the wood panel.
