Dome Tweeter with Composite Diaphragm — Eigenfrequency Analysis

Application ID: 129701


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.

This model example illustrates applications of this type that would nominally be built using the following products:
