The driving system of the speaker is constructed by a circular PZT bimorph, which is clamped on its boundary, An elastical coupling element is utilized between the bimorph and the speakercone.
The results have been applied to the CAD/CAM system for speakercone models, which has got a good effect.
上述成果已应用于纸盆模具CAD/CAM软件设计系统的实践中，并取得了良好的效果。
