The model of a panel with attached mass is developed and the modes of distributed mode loudspeaker (DML) have been analyzed with Rayleigh-Ritz method in this paper. Distribution of bending wave modes is determined not only by the geometrical and elastic parameters of panel but also by the mass attached on the panel, which can be predicted by our calculation. Therefore, the mass and position of exciters should be considered carefully by panel’s optimization program. And optimal result using generic algorithm (GA) is given in this paper.
