Analysis of the Nonrigid Behavior of a Loudspeaker Diaphram Using Modal Analysis
The behavior of a loudspeaker diaphragm beyond the piston range of operation has previously only been investigated using analytic techniques such as the Finite Element Method. An experimental method, Modal Analysis, is presented that allows a model to be developed from actual measurements. Previous problems in the measurement technique are overcome by the use of a non-contacting laser transducer. A step by step analysis of a typical driver is shown. After developing the modal model, it is possible to simulate structural modifications and to study the dynamic system response. Special application software is used for the measurement, analysis, and simulation.
