Radiation of Enclosed Loudspeaker in Baffle: Simulation Model and Results

Authors: Prokofieva, Elena

Abstract

A theoretical investigation of the conventional speaker, placed into a rigid wall, has been presented at AES 116 [1]. The quasi-dynamic approach to the loading force and pressure was introduced there. The speaker diaphragm was regarded as a number of concentric rings. The acoustic pressure and surface velocity is predicted using the first two approximations in [1]. These simulations show the difference between the real measurements and the analytical models, used with some standard assumptions from the classic theory of plates. The results suggest that the modelling process needs to become more specified. Hence, to simulate the behaviour of a standard suspension, the outer, clamped ring was given the characteristics of rubber, with non-linear deformations. The 4th approximation of the problem is formulated in this paper.
