METAL MATRIX COMPOSITE MATERIALS FOR ACOUSTIC APPLICATIONS

摘要

Loudspeaker diaphragms are made from a metal matrix composite sheet of substantially uniform thickness. The metal matrix sheet comprises ceramic particles distributed in a metal matrix, the ceramic particles having an average particle size from 0.1 micrometers to 20 micrometers. The metal matrix sheet has a substantially uniform thickness of 4 micrometers to 1,000 micrometers.
