Abstract

Distributed Mode Loudspeakers consist of a flat panel of a light and stiff material to which a mechanical exciter is attached, creating bending waves that are then radiated as sound fields. It can be used to build arrays for Wave Field Synthesis reproduction by using multiple exciters in a single vibrating surface. The exciter interaction with the panel, the panel material and the panel contour clamp conditions are some of the critical points that need to be evaluated and improved. In this paper, we address the edge boundary conditions influence on the quality of the emitted wave field. The measures of the wave
fields have been interpreted in the wavenumber domain, where the source radiation is decomposed into plane waves for arbitrary angles of incidence. Results show how the wave field is degraded when the boundary conditions are
modified.
