Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a speaker system mounting stand that can effectively prevent transmission of cabinet vibrations to a floor plate when a speaker system of a stereo device is mounted thereon.

[Conventional technology]

Conventionally, simple stands used for audio equipment, especially speaker systems, have been made by stacking concrete blocks, or specially made stands made of wood, metal rods, etc.

[Problem that the invention attempts to solve]

Generally, the speaker system is placed on a stand,
When used in a room with a normal floor structure, the conventional speaker system stand as described above supports the bottom plate of the speaker system over the entire surface or a fairly large area, or supports the bottom plate of the speaker system in the area where the vibration is most intense, such as the center of the bottom plate. Because it has a supporting structure that includes the cabinet, vibrations from the cabinet are directly transmitted to the floorboard, resulting in howling and unnecessary noise caused by the vibration of the floorboard, which deteriorates the quality of reproduced sound.

In addition, even if the speaker system stand is manufactured to support the four corners of the cabinet where the plate vibration level is lowest, the dimensions of the support part remain constant, so it can be used in the best condition when using speaker systems with different dimensions. I couldn't do it.

[Means for solving problems]

Eliminating the drawbacks of the conventional example described above, the speaker system mounting stand according to the present invention aims to support the corner portion of the cabinet plate with less vibration in a state where plate vibration is even more difficult to transmit. A truncated cone with a supporting shaft protruding from the top, four pillars each having at least one hole in the upper end surface into which the supporting shaft is inserted, and a connecting rod that connects the four pillars into a square column shape. The connecting rod connects the four pillars into a square prism shape, and the support shaft on the lower base of the truncated cone is rotated into one of the holes provided in the upper end surface of the pillar. It is characterized in that it is configured to be movably inserted and to support a speaker system by the upper base of the truncated cone.

[Effect]

In a speaker system stand having such a configuration, the area that contacts the wall surface of the speaker system is small, and the hole is located at an appropriate position when the support shaft on the lower base of the truncated cone is rotatably inserted into the upper end of the support. By selecting a rotatable truncated cone around an eccentric support shaft and moving the position of its upper and bottom surface, it is possible to support the vicinity of the corner where the vibration of the cabinet plate is least. Therefore, the amount of vibration from the cabinet plate transmitted to the floor plate is small, and no matter what size the cabinet is, its adverse effects can be prevented and the cabinet can be supported in the best possible condition.

〔Example〕

An embodiment of the speaker system stand of the present invention will be described in detail with reference to FIGS. 1 and 2.

Reference numeral 1 designates a truncated cone with a supporting shaft 2 protruding from an eccentric position on the lower base, and is made of brass, and the upper base supporting the speaker system is finished to approximately 0.8 cm ² .

Reference numeral 3 denotes a support column, and its upper end face is provided with five holes 4 into which the support shaft 2 is inserted.
is inserted, and the truncated cone 1 is mounted on the support column 1 so as to be rotatable around the support shaft 2.

Reference numeral 5 denotes a connecting rod that connects the four pillars 3, and the connecting rod 5 connects the four columns to the side edges of the square pillar.
The book supports 3 are arranged and connected.

In this example, the pillars and connecting rods are made of laminated reinforced wood obtained by laminating, compressing and heating thin wood boards impregnated with thermosetting synthetic resin, and although this material is relatively inexpensive, it is usually Compared to the case where wood is used, the mechanical impedance is higher because the material is denser than wood, making it even more difficult to transmit cabinet plate vibrations.

The truncated cone 1 is not limited to the dimensions of the upper and lower surfaces of the first half, but it is desirable that the truncated cone 1 abuts on the joint portion of the bottom plate of the speaker system on which it is mounted with the side plate where the plate vibration level is lowest, so the dimension of the upper and lower surfaces is 0.2. ~8
A range of about cm ² is appropriate.

For those with one hole provided on the top end of the column,
Although the adjustable range of the support position of the speaker system is narrower than when a plurality of speaker systems are provided, the manufacturing cost is low.

In addition, the greater the eccentricity of the supporting shaft protruding from the lower base of the conical truncated cone, the wider the adjustment range of the support position becomes. Depending on the selection, the present invention has an effect.

Regarding the materials used, it is not limited to the above-mentioned materials, but any strong material can be used, such as metal, ordinary wood, or synthetic resin reinforced with fillers, and is included in the scope of the utility model registration claim. As long as it has the configuration described above, it has the functions and effects of the present invention and is included in the technical scope of the present invention.

[Effect of idea]

In the speaker system stand according to the present invention described above, the upper base surface that comes into contact with the wall surface of the truncated conical speaker system attached to the upper end surface of the support column has a small area;
Moreover, by rotating the truncated cone rotatably attached to the upper end of the support column around an eccentric support shaft and moving the position of its upper base, it is possible to support the cabinet plate near the corner where it is least vibrated. , the amount of cabinet plate vibration transmitted to the floor plate is extremely small, which has the effect of preventing howling caused by the transmission of plate vibration to the floor plate and deterioration of reproduced sound quality due to unnecessary noise caused by floor plate vibration. .
