Analyzing resonances is essential when designing loudspeakers. Resonances can come from various sources in a loudspeaker, with the diaphragm being a significant one. There are numerous traditional approaches to address diaphragm resonances, each with its own benefits and drawbacks. A more advanced approach involves using innovative materials like composites.

This example is divided into two parts. In the first part, the extraction of homogenized material properties from composite materials with different microstructures is demonstrated. In the second part, an eigenfrequency analysis is carried out on a diaphragm, comparing conventional materials such as titanium with composites whose properties were obtained from the first analysis.
