Abstract：The model of sound field of a rigid cylindrical enclosure with a middle flexible panel is deduced by using Hamiltonian function and sound modal theory. The model allows the consideration of a wide variety of boundary conditions by means of continuous distributions of artifical springs along boundary of flexible panel. A general formulation considering the full coupling between the two cavities and the panel with different boundary conditions is developed. Analytical results intended to investigate two main issues are presented. One is that the rotational stiffness has less influence on the structural-acoustic coupling of the model and the panel velocity than the translational stiffness has，the other is that the sound response of cavity 2 caused by panel increases with the increase of the translational stiffness. The contribution of this paper is that it provides some supporting theoretically in engineering.
