Abstract

PURPOSE:To obtain a vibration preventing stand which forms the vibration preventing stand for a speaker, is heavy, good in external appearance and has a high friction coefficient with a speaker by containing the powder of a plasticizer and a lead compound into a polyvinyl chloride paste resin. CONSTITUTION:A plasticizer 70-120 weight part and a lead compound powder 800-2000 weight part are combined for a polyvinyl chloride paste range 100 weight part and a vibration preventing stand for a speaker is formed. While the stand is of a high density with the density 5g/cm<3> or above, the stand is fabricated to a block shape. The surface of the stand is colored by the addition of pigments. Thus, the vibration preventing stand for a speaker is obtained which is heavy, good in external appearance and has a high friction coefficient with the speaker.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vibration prevention stand for audio speakers. A vibration prevention stand for audio speakers is installed between the speaker and the floor, and prevents deterioration of sound quality caused by mutual influence between the floor and the speaker due to the vibration of the speaker being transmitted to the floor.

The common idea among these anti-vibration tables is that they are heavy. In other words, it follows the basic principle that heavy solids are difficult to vibrate. Other ideas, although not necessarily common, include reducing the vibration transmission efficiency by reducing the support area, reducing the transmission efficiency by providing a material or mechanism that absorbs vibration energy, or reducing the transmission efficiency by using a spring-like mechanism. The idea is to reduce transmission efficiency by

The basic idea of not deteriorating the sound of the speaker is that only the vibrating part on the surface of the speaker vibrates, and it is desirable that the part of the speaker box that holds the vibrating part not vibrate as much as possible. That's why good speakers are so heavy. Therefore, it is desirable that the anti-vibration stand supporting the speaker be heavy and highly effective in absorbing vibration energy in order to meet the above requirements. Furthermore, it is more desirable to suppress the movement of the speaker box by using a material with a high coefficient of friction for the contact portion with the speaker.

Anti-vibration rubber has a great effect in absorbing vibration energy, but its weight is too light and the spring-like mechanism is too strong, which considerably reduces the rate at which speaker vibration is transmitted to the floor, while suppressing the vibration of the speaker itself. shows no effect at all. Although the material itself has a high specific gravity, vibration damping alloys are light in weight because it is difficult to obtain large molded products, and unlike vibration damping rubber, they absorb vibration energy without developing a spring-like mechanism. Although it was said to be effective, it could not be said that the degree of effectiveness was high. The problem with wooden surfaces, which were made by filling the inside of the wood with sand or other material to make it heavier, was that the wood itself had a poor ability to absorb vibrations. On the other hand, anti-vibration tables made of resin had not been used until now, as they were thought to be fatal, perhaps due to their light weight. Although it is possible to increase the specific gravity by filling a large amount of high-density filler, such a system has a limited degree of freedom in shape.

[Function] The polyvinyl chloride base resin used in the present invention is characterized in that it maintains fluidity in the form of a sol even when mixed with a plasticizer at room temperature. 2
The product is made by heating and molding at a high temperature of about 30°C. Therefore, unlike other thermoplastic polymer materials, there is no need for a melt-mixing process. This is a great advantage when a large amount of filler must be blended as in the present invention, since there is no need to take into account wear of equipment during the melt-kneading process. In addition, in order to achieve high density, it is necessary to increase the amount of lead powder filled, but when filling with ordinary fillers such as iron oxide and calcium carbonate, it is about 600 parts by weight per 100 parts by weight of polyvinyl chloride base resin. If the sol is filled too high above the mouth, the viscosity of the sol will increase and the fluidity will be poor, making it difficult to mold.However, in the case of lead or lead compound powder, even if the sol is filled 800 kg or more, it is sufficient. By pouring this sol into a mold, heating and pressurizing it, it can be molded into various shapes and thicknesses.
1) To be done. This is a major feature of the present invention. In addition, the content of polyvinyl chloride paste resin in the obtained high-density damping material is at a mold mouth ratio of 10% or less,
Although the remaining components of 9096 or more are occupied by materials with poor coloring properties, the appearance of the polyvinyl chloride paste resin can be improved by adding pigments due to its excellent blue color. It is a characteristic.

The amount of plasticizer blended is determined appropriately for the purpose of imparting fluidity when mixed with the total amount of polyvinyl chloride paste resin and lead and lead compound powder, but usually it is 70 to 100 heavy engineering department
120 parts by weight is desirable. If the amount is less than 70 parts by weight, sufficient fluidity cannot be obtained, and if more than 12 parts by weight is added, the strength of the material will decrease.

Examples include dilead dioxide and dilead oxide. Particle size is 100
A thickness of μm or less is desirable. Lead having a particle size of more than 100 μm tends to settle quickly in a sol state, and thus lacks sol stability. As for the blending ratio, it is desirable to have as much lead and lead compound powder as possible from the viewpoint of moldability, workability, and strength, but if more than 2000 parts by weight is added to 100 parts by weight of polyvinyl chloride base resin, it will not flow. The properties of the molded product become poor, making molding difficult and the strength of the molded product also reduced. Moreover, if it is less than 800 parts by weight, the density will decrease. The shape and size of the anti-vibration stand for speakers of the present invention are the usual block size (width 10ca + length 20cm).

The anti-vibration stand for speakers of the present invention is made by blending polyvinyl chloride paste resin, plasticizer, lead or lead compound powder, stirring and mixing in a mixer to form a sol, which is preferably defoamed, poured into a mold, and heated. It can be obtained by methods such as molding. Furthermore, if necessary, scaly fillers such as mica, talc, and graphite, flame retardants, and the like may be included.

The blue method can be carried out by adding pigments. Compared to coloring by painting, it is less effective in hiding the gray color of lead powder, so it only produces a dark color tone. However, for audio-related equipment, dark tones are preferred, and the friction coefficient of the back surface is higher than that of painted colors, which can suppress lateral vibrations of speakers.
