A portable information handling system glass ceramic housing has a cut out section at an opening and a speaker chamber cover disposed in the opening to integrate a speaker at a bottom front side of the housing. A speaker coil couples to the housing section to align with a speaker magnet coupled to the speaker chamber cover to generate audible sound in a speaker chamber defined when the housing section couples over the opening. A polymer material is disposed between the housing section and housing, and the housing section is cut out with an upward curve, so that audible sound is directed upwards from the housing and towards an end user of the information handling system.
