THE INFLUENCE OF MAGNETOSTRICTIVE TRANSDUCER RADIATION PLATE MATERIAL ON RADIATION SOUND FIELD DISTRIBUTION
The radiant panel is transducer of the sound source output device,the installation space constraints under the condition of enrollment size,increase the radiation plate vibration amplitude of the focus of research.This paper only considering the influence of the materials of radiant panel vibration amplitude and has carried on the finite element software WORKBENCH and ATILA software analyzes the magneto strictive transducer radiant panel material influence on vibration amplitude frequency characteristics and the influence of sound field distribution inside the cavity.Results show that the same incentives and boundary condition,the aluminum material appeared radiant panel piston type when the frequency is highest,has the biggest output displacement which was of 4.48 to 24.8 times to the other materials panel; After joining the cavity body,aluminum radiant panel inside the cavity acoustic pressure amplitude is the largest and the panel radiated sound pressure amplitude is of 1.2 to 2.4 times than the other material.Above conclusion for frequency miniature transducer radiant panel provides a strong basis for the design of the work.
