异型扬声器纸盆几何形状数学模型的设计

Mathematical Model Designing for Geometrical Picture of Loudspeaker Paper Basin

构造了椭圆形和跑道形两类扬声器纸盆的数学模型．从理论上证明这两类数学模型的光滑性．给出了生成这两类模型的步骤，为开发、生产扬声器纸盆模具获得新的依据，对扬声器外形随意变化提供很大方便．该方法已经在计算机上模拟出三维图形，通过实验得到证实．

This article mainly talks about making the mathematical models of paper basin of the loudspeakers: oval loudspeaker and track loudspeaker. The smooth of the two kinds of models are proved theoretically. The procedure of forming the two types of molds has been provided. The new evidence of developing and producing amplifier paperbox molds has been obtained which makes it more convenient to do any change on the shape of the amplifiers. The procedure has been imitated into the threedimensional graph in computer and has been proved through experiments.
