Abstract
A gas adsorbing material is provided. Specifically, there is provided a molded matrix of a plurality of spherically-shaped gas adsorbing material. The individual spheres comprise particles of a highly porous gas adsorbing material and a binder. The plurality of spheres are mixed with a second binder material and molded into a desired shape for use in the back volume of an acoustic transducer such as a loudspeaker device, a microphone or a balanced armature receiver.
