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.

Abstract: An audio speaker having a speaker housing surrounding a back volume that is divided into a rear cavity behind a speaker driver and an adsorption cavity separated from the rear cavity by a permeable partition, is disclosed. More particularly, the adsorption cavity may be defined between the speaker housing and the permeable partition, and may be directly filled with adsorptive particles to adsorb gas during sound generation. The permeable partition may allow the gas to flow between the rear cavity and the adsorption cavity, and may retain the adsorptive particles within the adsorption cavity. Other embodiments are also described and claimed.

Abstract: An electronic device includes a housing having an opening comprising an audio port and a speaker assembly carried by the device housing. The speaker assembly includes a water ejection system having a diaphragm coupled to a magnetic driver and a mesh that covers the audio port where the diaphragm and the mesh together define an acoustic volume. When a water ejection signal is received at the magnetic driver, the magnetic driver is caused to move the diaphragm in a manner that ejects water contained within the acoustic volume out of the acoustic volume and through the mesh.
