Significance Tests on Design Factors Affecting the Frequency Performance of Spherical Cymbal Transducer

摘要

Orthogonal experiment was used to optimize the design of spherical cymbal transducer. Through variance analysis of orthogonal experiment results, the primary and secondary order that each design factor affects the frequency performance of spherical cymbal transducer has been found. At the same time, the significant level of each design factor has been gained. Those factors which have highly significant or significant effects on the frequency performance of spherical cymbal transducer should be considered carefully during design spherical cymbal transducer, and those factors which have no significant effects can be ignored. In this way, the design factors were reduced, and the design complexity of spherical cymbal transducer was simplified.
