In this paper, the calculus, which is a simple and effective method, is proposed to design the cone compound horn. And the structure has been analyzed applying the Ansys software. The horn is optimized and reconditioned using the optimum design function of Ansys, also the horn before and after optimization will be applied for impedance analysis and vibration property test. The result shows that the after optimization of the horn has a better vibration effect. Finally, the dynamic characteristics are analy
