Several types of implementation of panel loudspeakers(for example, distributed mode loudspeaker (DML))for are proposed. The diaphragm of a DML is thought as behave like a bending plate. The diaphragm of an electrostatic loudspeaker is thought move as a rigid plate. What is the difference of an acoustical sound field generation feature with each implementation? In this paper, we used models of same dimensional rectangular panel. One is a rigid diaphragm. Another is a bending panel that has an actuator in the center of it. We made directivity simulations. We made simulations of sound pressure distribution in a rectangular room. We could show less coherent SPL distribution in the case of a bending panel.
