Abstract:
An audio speaker having an adsorptive insert in a speaker back volume, is disclosed. More particularly, an embodiment includes an adsorptive insert having a rigid open-pore body formed by bonded adsorptive particles. The rigid open-pore body includes interconnected macropores that transport air from the speaker back volume to adsorptive micropores in the bonded adsorptive particles during sound generation. Other embodiments are also described and claimed.
