Optimal Material Parameter Estimation by Fitting Finite Element Simulations to Loudspeaker Measurements

  title={Optimal Material Parameter Estimation by Fitting Finite Element Simulations to Loudspeaker Measurements},
  author={William Cardenas and Wolfgang J. Klippel},
  journal={Journal of The Audio Engineering Society},
Important characteristics for the sound quality of loudspeakers like frequency response and directivity are determined by the size, geometry and material parameters of the components interfacing the acoustic field. The higher-order modes after cone break-up play and important role in wideband transducers and require a careful design of the cone, surround and other soft parts to achieve the desired performance. Finite Element Analysis is a powerful simulation tool but requires accurate material… 
Estimation of Optimal Values for Lumped Elements in a Finite Element — Lumped Parameter Model of a Loudspeaker
Finite element methods are progressively being utilized to assist in the continuous development of loudspeakers. The core of this paper is the method of lumping certain parts of the finite element ...


Distributed Mechanical Parameters of Loudspeakers Part 1: Measurements
The mechanical vibrations of loudspeaker drive units are described by a set of linear transfer functions and geometrical data which are measured at selected points on the surface of the radiator
Determining the Accuracy of Modal Parameter Estimation Methods
The most common type of modal testing system today uses an FFT analyzer to measure a set of Frequency Response Functions (FRFs) from a structure, and then uses a parameter estimation (curve fitting)
Modal Analysis Using the Singular Value Decomposition
Many methods exist for identifying modal parameters from experimental transfer function measurements. For frequency domain calculations, rational fraction polynomials have become the method of

Finite Element Model Reduction and Model Updating of structures for Control
Estimation and control of unmeasurable performance variables in complex large-scale systems is an important issue in systems and control. The preferred solution to this problem is to have a
The PolyMAX Frequency-Domain Method: A New Standard for Modal Parameter Estimation?
Recently, a new non-iterative frequency-domain parameter estimation method was proposed. It is based on a (weighted) least-squares approach and uses multiple-input-multiple-output frequency response
Nonlinear eigenvalue problems: a challenge for modern eigenvalue methods
A new linearization technique is briefly introduced and demonstrated how it can be used to improve structure preservation and with this the accuracy and efficiency of linearization based methods.
