Abstract

An information handling system housing forms an audio chamber within which a speaker generates audible noise based upon audible information. An adaptive material, such as an electroactive polymer, is disposed at an opening formed in the audio chamber to selectively expand to increase the audio chamber size and contract to decrease the audio chamber size. An increased audio chamber volume enhances audible noise, such as music or audio associated with audiovisual content. A decrease audio chamber can improve airflow within the housing, such as during times of thermal stress.
