Convention Paper

Automated Design of Loudspeaker Diaphragm Profile by Optimizing the Simulated Radiated Sound Field with Experimental Validation

Authors: Macey, Patrick; Griffiths, Kelvin

AES Convention 128 · Paper 7995 · May 2010

Abstract

Loudspeaker designers often aim to reduce acoustic effects of diaphragm resonance from the frequency and power response, however even in the domain of simulation models this often requires considerable trial and error to produce a satisfactory outcome.

A modelling platform to simulate loudspeakers is presented, which can automatically cycle through vast permutations guided by a carefully considered objective function until convergence is achieved, and importantly, the entire iterative effort is accommodated by the computer.

Experience and knowledge must make an initial evaluation of which factors are important in achieving a desired result a priori. Once prepared, the basis of a rapid loudspeaker development tool is formed which can return a tangible resource profit when compared to successive manual efforts to optimise loudspeaker components.
