2. Description of the Related Art For example, a conventional audio equipment stand used as a speaker base has a shape as shown in FIGS. The table 20 shown in FIGS. 5A and 5B as a plan view and a side view includes an upper plane 21 and a lower plane 22.
And is used as shown in FIG. 7, for example. In FIG. 7, 90 is a speaker cabinet,
Reference numeral 91 indicates a speaker unit, and 92 indicates a floor (installation surface).
FIG. 7A shows a state of the speaker viewed from the front side, and FIG.
(B) has shown the state which looked up at the speaker from the floor 92 side. As can be seen from these figures, for example, three pedestals 20 are arranged on the floor 92, and the speaker cabinet 90 is placed on the pedestals.

A table 30 shown as a plan view and a side view in FIGS. 6 (a) and 6 (b) has a cone-shaped portion 31 at the upper portion and a tip 32, and a lower portion in the shape of a cylinder having a lower plane. It has a shape having 33. Then, FIG. 8 (a) shows the state viewed from the front side of the speaker, and FIG. 8 (b) shows the floor 9
As shown by looking up the speaker from the 2 side,
For example, three pedestals 30 are arranged on the floor 92, and the speaker cabinet 90 is placed on the pedestals.

[0004]

However, in the table 20 of the type shown in FIG. 5, the contact portion between the speaker cabinet 90 and the table 20 and the table 2 are as shown in FIG.
Since the contact portion between 0 and the floor 92 is in surface contact, the pressure of the contact surface is low, and the fulcrum of the speaker cabinet 90 becomes unclear when placed, and rattling easily occurs. The same can be said for the table 30 of the type shown in FIG. 6 because the contact portion between the table 30 and the floor 92 is in surface contact. And from these things, the conventional stand 2
In Nos. 0 and 30, there was a problem that vibration was generated in the speaker, and as a result, the sound quality of the output sound was deteriorated. The same can be said for such a problem as a stand for an amplifier, a player, or the like.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a stand that can be placed on an audio device without rattling and does not generate extra vibration. To do. For this reason, as an audio equipment stand on which three or more audio equipments are to be placed, the upper part has a shape in which the approximate center is the end point, and the lower part has the end point. Three units are provided so that three points form the tip. Also in this case,
The upper side portion and the lower side portion may be integrally formed.

[0006]

With the above structure, in the audio equipment stand according to the present invention, both the contact area for the audio equipment and the contact area for the installation surface such as the floor become point contact, improving the pressure at the contact area and clarifying the fulcrum. Can be realized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention will be described below with reference to FIGS. 1 and 2, the second embodiment with reference to FIG. 3, and the third embodiment with reference to FIG.

1A, 1B, and 1C are a plan view, a side view, and a bottom view of a stand according to the first embodiment. As can be seen from the figure, this stand 1 has an upper side portion 2 and a lower side portion 3, the upper side portion 1 has a conical shape, and a substantially center is a tip point 4. Further, three conical leg portions 5 are formed at positions of 120 ° on the lower side portion, and a tip point 6 is formed on each leg portion 5.

FIG. 2 shows a state in which speakers are arranged using such a stand 1. FIG. 2A shows a state as viewed from the front of the speaker, and FIG. 2B shows a state as viewed from the floor 92 side. For example, three pedestals 1 are arranged on the floor 92 in a state where, for example, each vertex position of a substantially equilateral triangle is arranged, and the speaker cabinet 90 is placed on the three pedestals 1.

At this time, the speaker cabinet 90 and each stand 1 are in contact with each other only at the tip point 4, that is, the speaker cabinet 90 is supported by the three stands 1 at three points. In addition, each stand 1 has a floor 9
It is supported at 3 points with respect to 2 by 3 tip points 6.

As described above, since each stand 1 and the speaker cabinet 90 are in point contact with each other, and each stand 1 and the floor 92 are also in point contact with each other, the pressure at the contact portion is improved and the fulcrum is also supported. Therefore, the rattling of the stand 1 with respect to the floor 92 and the rattling of the speaker cabinet 90 with respect to the stand 1 are eliminated, and unnecessary vibration is not applied to the speaker cabinet 90, and the output sound from the speaker unit 91 is eliminated. The influence of vibration is eliminated, and clear sound quality output can be obtained.

Although the speaker cabinet 90 is mounted by using the three pedestals 1, four or more may be used. However, reducing the number of contact points is more effective in preventing rattling, and it is most appropriate to use three contact points.

As a method for manufacturing such a stand 1, various methods such as shaving, molding, and adhering or fitting a molded product to a machined product can be considered. For example, the upper side portion and the lower side portion (each leg portion 5) are molded as separate bodies,
A method of adhering this or a method of molding them all together is conceivable. When the stand 1 is used for the speaker as described above, it is preferably integrally molded.

The material may be wood, plastic, ceramics, glass, or the like. Especially when it is made of wood, it is preferable to cut it out using a material such as zelkova or cherry blossoms, and a plywood board member known as particle board may be used. Further, as the plastic, liquid crystal polymer, polystyrene, acrylonitrile-butadiene-styrene, polymethylmethacrylate, polypropylene and the like can be considered.
Of course, there are various suitable materials other than those exemplified.

3 (a), 3 (b) and 3 (c) are a plan view, a side view and a bottom view of a stand 1 according to a second embodiment of the present invention, in which case the upper portion 2 is a triangular pyramid. The end point 4 is formed to have a shape. In addition, three triangular pyramid-shaped legs 5 are formed in the lower portion 3, and three tip points 6 are formed.

4 (a), (b) and (c) are a plan view, a side view and a bottom view of a stand 1 according to a third embodiment of the present invention, in which case the upper part 2 has a hemispherical shape. As a result, a gentle tip point 4 is formed. Further, three leg portions 5 having a hemispherical shape are formed in the lower side portion 3, and three gentle tip points 6 are formed.

The pedestals 1 of the second and third embodiments are also used in the same manner as in the example of FIG. 2, for example, three pedestals 1 are used to support the tip points 4 of the pedestals 1 in contact with the speaker cabinet 90. ,
Further, each stand 1 is in contact with the floor 92 by its three tip points 6. Therefore, the same effect as that of the first embodiment can be obtained. In addition, in the second and third embodiments,
Various manufacturing methods and materials can be considered as in the first embodiment.

Although the embodiments of the present invention have been described above, various shapes other than these embodiments can be considered as the shape of the stand for audio equipment of the present invention. In either case, the point contact part may be formed in the upper part and the three point contact part may be formed in the lower part. Further, although the example in which it is used as the stand for the speaker has been described, it goes without saying that it is suitable for use as the stand for various audio equipment such as an amplifier, a CD player, a record player, and a tape player.

[0019]

As described above, in the audio equipment stand according to the present invention, the upper side portion is shaped such that its approximate center is the tip point, and this tip point is the contact point (support point) for the audio equipment. At the same time, the lower part is provided with three units each having a tip point, and the three points serve as tips.
By supporting at three points with respect to the installation surface such as the floor, when three or more of these audio equipment stands are placed on the stand, a contact part with the audio equipment is contacted. Also, both of the contact portions with respect to the installation surface such as the floor are point-contacted, and the pressure at the contact portion can be improved and the fulcrum can be clarified, whereby unnecessary rattling can be suppressed. Then, since the vibration to the audio equipment is eliminated, the sound quality of the audio equipment is improved.
