In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

The present document describes techniques associated with a textile-material model for vibroacoustic structural simulation. The techniques described herein provide a nontrivial methodology to test a textile and simplify its representation, which can enable prediction of acoustic performance (e.g., rub and buzz) of an electronic-speaker device having a textile mounted thereon. The textile is modeled as a textile-material model based on an elongation stiffness obtained from a time-temperature superposition curve of the textile, which is based on a dynamic mechanical analysis test of the textile in each of course and wale directions. The textile-material model is then applied to an assembly model of the electronic-speaker device to simulate a vibroacoustic response of the textile relative to the assembly model to predict a likelihood of rub and buzz.

This document describes textile assemblies for speakers, including textile assemblies with inlaid tensioning yarns, and associated apparatuses and methods. The textile assembly includes a textile body () with inlaid tensioning yarns (). The textile assembly () may be a fully-fashioned textile swatch. The tensioning yarns are inlaid at intervals in the textile body but can slide within or be pulled through the textile body. Further, the tensioning yarns have ends () that are accessible near the edges of the textile body for various reasons. First, pulling on them while the textile assembly is on an acoustic device () tensions the tensioning yarns such that they limit movement of the textile assembly and break up vibration modes. Second, their ends can be tied directly to, formed into loops to hook over, or wound around, features () on the acoustic device to removably secure the textile assembly to the acoustic device.
