Description

[Detailed description of the invention] [Industrial application field] This invention relates to a spacer that is used between a stand or a floorboard on which a speaker system of a stereo device is placed, and supports the speaker system in the best possible condition. The present invention relates to a spacer for mounting a speaker system that can handle extremely diverse usage conditions.

[Prior Art] When installing audio equipment, especially speaker systems, it is necessary to lift the treble unit off the floor so that it is at ear level. In the past, simple devices used stacked concrete blocks or specially made stands made of wood, metal rods, etc.

[Problem that the invention attempts to solve] Generally, a speaker system is placed on a stand,
When used in a room with a normal floor structure, conventional speaker system stands have a structure that supports the entire bottom plate of the speaker system, including the parts where the plate vibration is most intense, such as the entire surface or the center, so that the cabinet vibration does not directly affect the speaker system. This may be transmitted to the floorboard, causing howling, or unnecessary noise due to the vibration of the floorboard may deteriorate the playback quality, or if the cabinet is supported by the entire bottom board, the flatness may be poor and there may be a gap between it and the floorboard or stand. may occur, noise may occur,
It has the disadvantage that vibration causes slippage and deteriorates the localization of reproduced sound, and even if the structure allows for vertical height adjustment, it cannot be used with any size speaker system. However, it also has the disadvantage that no consideration has been taken to avoid the central part of the bottom plate and to support it in as small an area as possible.

[Means for solving the problem] Except for the drawbacks of the conventional example described above, a speaker system for mounting a speaker system that can support a corner part with less vibration of the cabinet plate for a speaker system of any size. The speaker system mounting spacer according to the present invention, which aims to obtain a spacer, has four approximately triangular surfaces a, b, c, and d.
The main body is made of a solid material and has a tetrahedral shape and has four vertices A, B, C, and D opposite to the four faces. Two adjacent faces of the four faces are planar, and the remaining two faces are planar. A small cusp 1 is formed near the apex of each surface, and a vertex facing one of the two planar surfaces and one of the remaining two surfaces. It is characterized in that the opposite apex forms a truncated truncated pyramidal portion 2.

[Function] The spacer for mounting a speaker system having such a configuration can be used in various ways, as described below, depending on the purpose and place of use.

1. Face the surface with the small cusp 1 toward the floor 21,
If installed so that the apex supports the cabinet 22, the sharp tip will slightly sink into the floor 21 and the cabinet 22, and the contact area will be the smallest, plate vibration will not be transmitted, and no slippage will occur, which will improve the quality of the reproduced sound. Localization does not deteriorate. [Figure 2a] 2. Face the surface with the small cusp 1 toward the floor 21,
If the truncated truncated pyramid shaped part 2 is installed so as to be in contact with the cabinet 22, the small pointed protrusion 1 will not sink into the cabinet 22, so that the cabinet 22 will not be damaged. [Figure 2b] 3. If the cabinet 22 is installed so that the flat surface faces the floor 21 and the apex supports the cabinet 22, the floor 21 can be prevented from being damaged. [Fig. 2c] 4 If the flat surface is directed toward the floor 21 and the truncated truncated pyramidal part 2 is installed so as to be in contact with the cabinet 22, the small pointed protrusion 1 will not sink into the cabinet, so the cabinet 22, and furthermore, the floor surface 21 can be prevented from being damaged. [Fig. 2 d] Note that in the second, third, and fourth usage methods, the spacer makes surface contact with the cabinet or floor, but compared to conventional mounting tables, the contact surface is extremely small. Since it is small, the amount of cabinet vibration transmitted is small, and since the frictional force on the contact surface is large, slippage is less likely to occur.

[Example] As shown in FIGS. 1 and 2, the speaker system mounting spacer of the present invention is made of cast metal and has four substantially triangular surfaces a, b, c, and d, and each of the four surfaces Of the four faces of the main body, which has a tetrahedral shape and has four vertices A, B, C, and D facing each other, two adjacent faces d and c are planar, and the remaining two faces a,
A triangular pyramid is formed as a small cusp 1 near the apex of b, and one of the two planar surfaces c and d (d in FIG.
the vertex D opposite to the surface) and the remaining two surfaces a and b
The apex B facing any one of the surfaces (plane b in FIG. 1) forms a truncated truncated pyramid-shaped portion 2, respectively.

It should be noted that the shape of the small pointed protrusion is not limited to the triangular pyramid as in this embodiment, but also has a pointed shape such as a conical shape, which is within the technical scope of the present invention as long as it has the above-described function.

Further, the material is not limited to that of this embodiment, and any strong material can be used, such as wood or synthetic resin reinforced with a filler.

[Effects of the invention] The spacer for mounting a speaker system according to the invention described above supports the small area of the cabinet where plate vibration is low, thereby preventing howling and unnecessary noise caused by floorboard vibration from degrading the playback sound quality. This not only prevents the negative effects of cabinet plate vibration on the floorboard, such as deterioration, but also allows the height to be adjusted extremely freely.
