Ring Element Model: Program Results
AES Convention 120 · Paper 6839 · May 2006
Abstract
The new modelling method was described in a series of papers presented at AES conventions in 2004-2005 ([1]-[3]). In the proposed model the general approach is to represent a cone driver as a set of rings, loaded by a concentric force, applied around the lower element's edge. The ring element is preferred to the finite element model due to its simple yet precise driver simulation.
The standard theoretical model of the radiating piston was initially considered. The problems inherent to this approach were highlighted, and the model was improved by removing standard assumptions one-by-one and replacing them with more complex calculation procedures for improved simulation. The first group of assumptions is programmed and compared against the real measurements and analytical calculation. The advantages of each model are studied and an explanation of how each of the standard theoretical assumptions affects the final result is provided. The possibilities to use different models in preliminary speaker design are also discussed in this paper.
