Study results from both theory and computer simulation were shown in the paper. According to the fact that different characteristics of sound field are displayed with different excited frequency on spherical shell, in the case of different ratio of spherical shell thickness to radius, the pressure directivity of the model can conform to that of the prototype rather well by adjusting the excited frequency of the model. Of course the modification of numerical scale factor is required, in order to make the identity of nondimensional pressure of two systems.

For theoretical analysis, the simulation models of radiating panels with different designs of stiffeners were constructed using the software ANSYS. The amplitudes and the phases of these panels were obtained from the analyses of the simulation models using given system parameters such as spring constants of suspension and damper, the thrust of the voice coil and the damping ratio of the loudspeaker system, which were measured from experiments. Then, we use the amplitudes and the phases in the program of calculation of sound pressure level to simulate the behaviors of sound radiation of the loudspeakers. Through the comparison between the curves of sound pressure response measured by the sound measurement system MLSSA and the ones simulated by computer, we can find out the reason causing the drops in sound pressure curves and the direction to improve the loudspeaker system further. Finally, the discrepancies between the results of experiment and these of simulation were discussed.
