力学分布式参数描述了扬声器单元的振动与声辐射面之间的关系。这些参数是预测声压输出和把总的振动分解成不同模态或是与声压有关的分量的基础。这种分析把声学与力学问题分离开来,表明了其与几何特性、材料属性之间的关系,并给出了实际改善的方向。利用这种新的扬声器诊断方法来对设计优化中的常见问题进行讨论。
Mechanics The distributed parameters describe the relationship between the vibration of the speaker unit and the sound radiation surface. These parameters are the basis for predicting the sound pressure output and the components that decompose the total vibration into different modalities or sound pressure. This analysis separates the problems of acoustics and mechanics, shows the relationship between them and the geometrical and material properties, and gives the direction of the actual improvement. Use this new speaker diagnostics to discuss common problems in design optimization.
