Giant Magnetostrictive Material Exciter for Panel Loudspeaker

摘要

The exciter component in a panel loudspeaker has a profound effect on the overall performance of the system. The equivalent circuit analysis of the combination of giant magnetostrictive material exciter and distributed mode panel is introduced and how exciter parameters influence panel loudspeaker's performance is discussed. Numerical predictions are given in order to show how these influences are manifested.
