Application of amorphous alloy and/or high-entropy alloy in gong in minute repeater

Abstract

The invention discloses an application of an amorphous alloy and/or a high-entropy alloy in a gong of a minute repeater. The amorphous alloy and the high-entropy alloy have lower elastic modulus, smaller damping to sound, larger and stable amplitude and good anti-relaxation effect, and when the amorphous alloy and the high-entropy alloy are used on the gong of the minute repeater, the time telling sound quality is clear.

Description

technical field [0001] The invention relates to the technical field of application of materials, and more particularly to the application of an amorphous alloy and / or high-entropy alloy to a gong in a minute repeater. Background technique [0002] The minute repeater, also known as the three-reed watch, can tell the time of "hour", "engraved" and "minute" according to the different sounds of the three springs, which is the result of the ingenious use of acoustics and dynamics. The sound of the three questions comes from the hammer hitting the gong. The whole gong is composed of a metal base connected with two ring-shaped gongs. Because the lengths of the two gongs are different, when the hammer strikes, It will emit high and low sounds with different scales, so that the time can be distinguished by hearing. Therefore, the sound quality of the timekeeping has become the decisive factor in evaluating the quality of the minute repeater, and also determines its price. Cheaper ...

AI Technical Summary

Problems solved by technology

But the gong may deform excessively due to its own weight

Due to the limited space inside the case where the gong sits, it can easily come into undesired contact with adjacent parts

This constitutes a defect of gongs made of gold or any metal with high density and low modulus of elasticity
