Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a speaker enclosure.

(B) Problems to be solved by the prior art / device The prior art is shown in FIG.

In the drawing, 1 is an enclosure material for covering one surface of a plate 1a with a PVC sheet 1b, 2 is a first surface of the enclosure, 2a is a first plate 1a processed to form a first surface 2 on the plate 1a. 3 is a second surface of the enclosure, 3a is a second processed portion formed into a plate 1a to form the second surface 3, and 4 is a first surface 2 and a second surface 3 Along the ridgeline 5
It is a columnar rod provided between the first processing part 2a and the second processing part 3a.

The first processing portion 2a and the rod 4, the second processing portion 3a and the rod 4, and the PVC sheet 1b and the rod 4 are bonded to each other with an adhesive (not shown). The shape of 5 is such that it becomes a part of the circumference of the rod 4 having a radius r.

However, the above-described conventional one has a problem that it is difficult to obtain a ridge portion shape other than the above.

Also, as described in Japanese Utility Model Application Laid-Open No. 63-138796, a plate material, one surface of which is covered with a surface material such as a PVC sheet, is cut into a groove and bent at this processed portion to form an enclosure. Although there is a forming technique, it is impossible to form a curved surface at a corner of the enclosure because the plate material is processed after the surface material is bonded to the plate material in advance.

Still further, as a prior art, disclosed in Japanese Utility Model Application Laid-Open No. 57-40348, a plate material using a corner material provided with two convex portions which are fitted with concave portions at the ends and concave portions thereof. There is a technique of joining together and then bonding a PVC sheet to the surface to form an enclosure, but the work of attaching the PVC sheet to the surface after the enclosure is formed is technically difficult and has a problem in productivity. .

This invention has been made in view of the above points,
Its purpose is to be able to obtain many kinds of ridge shape, and to improve sound quality,
An object of the present invention is to provide a speaker enclosure that is easy to implement.

(C) Means for Solving the Problem The loudspeaker enclosure of the present invention processes a portion other than the surface material of a plate whose one surface is covered with a surface material such as a PVC sheet, and attaches the plate to the A loudspeaker enclosure configured to form at least two surfaces by bending at a processed portion, comprising a flat plate portion and a ridge line forming portion provided along one end on a long side of the flat plate portion, A ridge line forming portion provided on the side of the ridge line forming portion having a cross section in a longitudinal direction, the ridge line forming portion being made of an elastic body such as rubber having a curve or a straight line wider than the thickness of the flat plate portion or a cross-sectional portion of a combination thereof; The end of the plate forming the first surface, which is one of the two surfaces, and the end of the plate forming the second surface, which is the other of the two surfaces, are joined via the flat plate with the part. ,
The ridge line forming portion forms the ridge line shape of the two surfaces.

(D) Function According to the present invention, the shape of the ridge line portion is determined based on the shape of the portion of the elastic material in contact with the PVC sheet.

For this reason, many types of ridge shapes can be easily obtained.

In addition, since the elastic material acts to reduce unnecessary vibration of the enclosure, sound quality is improved.

(E) Embodiment An embodiment of a speaker enclosure according to the present invention will be described with reference to FIG.

The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

In the figure, 2A is a first processed part processed into a plate 1a to form a first surface 2, and 3A is a second processed part processed into a plate 1a to form a second surface 3. , 6 are a first processed portion 2A and a second processed portion along a ridgeline 5 between the first surface 2 and the second surface 3.
Elastic material made of rubber provided between 3A and 6A is a PVC sheet
This is a ridge portion shape forming portion of the elastic material 6 which is in contact with 1b and forms the shape of the ridge portion 5.

Then, the first processed portion 2A and the elastic member 6 and the second processed portion 3A
And the elastic material 6, and the PVC sheet 1b and the elastic material 6 are bonded to each other with an adhesive, so that the shape of the ridge portion 5 is determined based on the ridge shape forming portion 6A of the elastic material 6.

FIG. 1C shows an embodiment in which the top plate 7 and the side plate 8 are formed of the enclosure material 1.

The elastic member 6 may be made of a material other than rubber as long as it has elasticity.

(F) Effect of the Invention According to the loudspeaker enclosure according to the invention, the above-described configuration provides the following effects.

Various curved surface shapes of the ridge portion can be easily obtained.

Since the elastic material reduces unnecessary vibration of the enclosure, sound quality is improved.

Even if the ridge is hit, deformation can be prevented because of the elastic material.

In addition, it has excellent features such as simple structure and easy implementation since it can be configured at low cost.
