Loudspeaker Vibro-Acoustic Computational Analysis Methods and Experimental Validation
View through CrossRef
Abstract
In this paper the results are reported of a computational analysis aimed at evaluating the sound field emitted by a loudspeaker as a production line commercial product and optimizing its working as a prototype. The elasto-aeoustic characteristics of the loudspeaker have been simulated by means of a commercial computational code. The system fluid/structural model as input to the acoustic analysis has been developed by the finite element code. The results on the emitted sound field have been computed as frequency response functions at the loudspeaker horn groove and acoustic pressure distributions on different planes. Such results achieved by means of 2D/3D finite element (FEM) and boundary element (BEM) coupled analysis methods have been compared and validated by experimental measurement procedures.
