期使用に堪えられないという欠点があった。(Prior art) Generally, a material with small mass and large internal loss is required as a vibration material for audio equipment, and thin bodies of magnesium, titanium, and aluminum are used to meet all of these requirements. It is something. Especially among these, the magnesium thin body is the most lightweight, so it is the most lightweight.
It was said to be. However, since magnesium has poor corrosion resistance, it suffers from poor sound quality due to pitting, etc., and has the disadvantage that it cannot withstand long-term use.
更に従来のマグネシウムの薄状体は圧延などの二次加工
により箔の如く薄状体とするため加工による歪等をうけ
音響機器として重要な特性である減衰能を低下せしめる
ものであった。Furthermore, since conventional magnesium thin bodies are made into foil-like thin bodies through secondary processing such as rolling, they are subject to distortions and the like due to the processing, reducing their attenuation ability, which is an important characteristic for audio equipment.
（発明が解決しようとする問題点）

機器用振動材を開発したものである。(Problems to be Solved by the Invention) The present invention has been developed as a result of extensive research in view of the current situation, and has been developed for use in audio equipment using a thin body of magnesium or magnesium alloy (hereinafter referred to as magnesium) that has excellent corrosion resistance and mechanical performance. This is a vibration material developed.

。In other words, a factor that has an important effect on the corrosion resistance of magnesium is the presence of small amounts of impurities such as iron, nickel, and copper in magnesium. It can be kept to a minimum. Further, it is thought that corrosion resistance is greatly influenced by the unrestrictedness of the components within the material and the non-uniform distribution of the crystal structure. Such non-uniform distribution creates a local potential difference, forming a local battery and promoting corrosion resistance.

が低下するようなことがない。(Function) In the present invention, magnesium is heated to form a molten metal and then rapidly cooled to form a thin body such as a foil, so that the composition becomes uniform and the crystal structure in particular becomes fine. Further, in the present invention, the magnesium is not subjected to any secondary processing while it is a cast product, so there is no reduction in damping capacity.
