Abstract
The sound radiation properties of a striped panel
loudspeaker are modified in this study. The panel
loudspeaker is based on Electromechanical film (EMFi) and
consists of 14 individual sound radiating areas in form
of narrow stripes. Each stripe can be driven individually
so that the panel radiation pattern can be modified and
it can be used as a directivity-controlled sound source
in audio applications. The performance of the panel was
analyzed using an acoustical boundary element method
(BEM) model. For real-time directivity control, an
algorithm was developed to process the input signals to
gain appropriate radiation patterns. The measurements
carried out in anechoic conditions were used to verify
that the striped EMFi panel operates according to the
simulations and that it produces the desired directivity
pattern.
