英文摘要：

Based on the simply supported plate used in the active acoustic strutting, the influences of the plate parameters and the different kinds of excited forces on active acoustic structure are presented. The computer simulating results indicate that the characteristic parameters of the plates are reasonable approximations to the vibration modes. The applications of the clamped plate into active acoustic structure are also studied.
