DIAPHRAGM FOR ACOUSTIC TRANSDUCER

摘要

PURPOSE:To make a diaphragm light-weight and improve the diaphragm reproducing frequency characteristic, by using the magnesium-boron alloy where magnesium and boron are main components. CONSTITUTION:A diaphragm is formed from the magnesium-boron alloy where magnesium and boron are main components. Boron content is defined as 0.1- 10wt%. Further, the magnesium-boron-cerium alloy where 0.2-5wt% cerium is added to the magnesium-boron alloy may be used.
