The Non-rigid Surface Acoustic Concave Mirror Model and Sound Field Analysis

摘要：

The focused acoustic field of impedance surface acoustic concave reflector was studied by theoretical calculation. The influence of the different material parameters of reflector covering layers to the focused intensity and the beam partner were analyzed. The results showed that the main influencing factors to the focused acoustic field characteristics are the real part of admittance when the real part increase, the reflector focus ability reduced largely. But it is less influenced to the width of main lobe, and the side-lobe is decreased.
