1. A method of modeling a textile material for vibroacoustic structural simulation, the method comprising:

determining textile-level properties of a textile swatch;

determining, using the textile-level properties, an elongation stiffness of the textile swatch in each of a course direction and a wale direction;

generating, based on the determined elongation stiffness of the textile swatch, a textile-material model of the textile swatch;

applying the textile-material model to an assembly model representing an electronic-speaker device having one or more audio components;

simulating a vibroacoustic response of the textile swatch using the assembly model, the simulating including applying:

boundary conditions representing strain on the textile swatch; and

force inputs representing audio output by the one or more audio components of the electronic-speaker device; and

identifying, based on the simulated vibroacoustic response, frequencies that cause displacement of the textile swatch relative to surrounding areas sufficient for the textile swatch to vibrationally contact a component of the electronic-speaker device that is proximate to the textile swatch.
