成串-
But the sound field generated by this kind of transducers in medium has s ome " congenital " shortcomings : there always exist zero areas in sound - axes of near - field however we change the frequencies and radii of transducers, so we need to look for better radiate transducers. in this dissertation, we design and make two kinds of radiate transducers : bunchiness control transducer with electric polarity division and gaussian transducer
然而，這種類型的換能器在媒質中產生的輻射聲場，有其「先天性」的不足之處，在近場中無論平面活塞的頻率和半徑如何變化，軸上和沿徑向上都呈現出極大和極小交替分佈的干涉現象，因此我們有必要繼續尋求更為理想的輻射形式。
