optimum design - Opis:
- This paper presents a novel method for optimizing the directivity of the sound emission from the diaphragm of an electro dynamic loudspeaker. The analysis of the diaphragm is performed by finite element analysis of the structural dynamic behaviour and using the boundary element method for the acoustic analysis. Through optimization of a dead mass distribution on the diaphragm, or of the shape of the mid-surface of the diaphragm, it has been possible to improve its directivity properties for sound emission. Several illustrative examples are presented at the end of the paper.
