Aspects are disclosed of an apparatus comprising an assemblage of beads. The assemblage includes a plurality of beads formed from a zeolite and a polymeric binder. At least one bead in the plurality of beads has a shape including a base shape having a continuous exterior formed of a first dome portion and a second dome portion, the first and second dome portions being joined together to form a spheroid with a polar axis, a polar dimension along the polar axis, and a transverse dimension normal to the polar axis, and an indentation formed in one of the first and second domed portions, the indentation having a depth and extending toward a center of the base shape along and in the direction of the polar axis and a width in the direction normal to the polar axis.

Zeolitic material for improving loudspeaker performance

Aspects are disclosed of a filler for occupying a volume. The filler includes an expandable filler positioned in the volume so that it occupies a percentage of the volume. The expandable filler can permanently expand from a first dimension to a second dimension upon the application of an expansion trigger. The filler also includes an acoustic filler made up of a plurality of acoustically active beads positioned with the expandable filler in the volume so that the acoustic filler can adsorb gas flowing into the volume. Other embodiments are disclosed and claimed.
