Abstract

Multiactuator panels (MAPs) are an extension of the distribute mode technology in order to be employed for Wave Field Synthesis (WFS) applications. In this paper, a special type of semiclamped boundary condition that exhibited proper results in recent convention papers by the authors, is used for setting a MAP ready for use. For that purpose, the surface velocity over specific points has been measured with a Laser Doppler Vibrometer, paying special attention to representative exciter locations: central area, edge and corners. For an understanding of the sound-generating behavior of the panel, measures were taken both for exciters accommodated in a roughly centered line, as in the rest of MAP prototypes and for an identical array of exciters positioned at the upper side of the panel, in which the behavior was still acceptable for WFS purposes. Experiments were also conducted to analyze the role that the exciter coupling ring, used to physically attach transducers to panel, has on the vibrational behavior and radiated sound.
