Abstract:This paper aims to simulate the sound field of rectangular small enclosure excited by panel loudspeaker with FEM. Firstly, in order to testify the fluid-structure interaction theory in the field of acoustics calculation, coupled modal and uncoupled modal of loudspeaker and air were established. Result of harmonic response analysis shows that the vibration amplitude of uncoupled case is larger than the coupled case. The result just is in harmony with the fact. So when modeling the sound field, fluid-structure c… Show more
