Accurate Methods for Determining the Low-Frequency Parameters of Electro-Mechanical-Acoustic Transducers with BLI Excitation
Various new methods are described which allow high accuracy in measuring small-signal transducer parameters. The tests are non-destructive and are applied to complete operating transducers. Analysis of these accurate measurements leads to a better understanding of the limitations of the design of typical transducers and to improved modelling of the equivalent electrical circuit.
