Spherical-cymbal transducer, which is derived from the traditional cymbal transducer, has demonstrated better vibration displacement and resonance frequency performance than the traditional cymbal transducer. In order to realize the optimal design of the spherical-cymbal transducer, orthogonal experiment is used to optimize the design parameters of the spherical-cymbal transducer. Weighted comprehensive point-rating method (WCPM) is used to process the orthogonal experiment results for multi indexes, and intuitionistic analysis of the weighted comprehensive score is used to optimize the level of each design parameter. The optimal combination of all design parameters is gained. Test results show that the optimized spherical-cymbal transducer has the best integrative performance.
