摘　　要：平板扬声器的声重放质量与传统高保真扬声器系统相比仍有较大差距,要从根本上解决这个问题就必须加强理论研究。基于对平板扬声器电-力参数测量、箱体内衬微穿孔吸声材料、驱动器以及附加质量位置优化的理论研究和实验测试,提出了若干种提高平板扬声器声性能的方法。The reproduced sound quality of panel speaker is still far from the conventional high fidelity loudspeaker system, which can only he solved by enhancing the theoretical study. Based on the theoretical and experimental studies in electrical and mechanical parameters, micro-perforated absorption material in the box, and positions optimization of the actuators and attached masses on the panel, several optimization methods for the acoustic performance of panel speaker are proposed.
