To provide a speaker assembly having a reduced front volume.
A portable electronic device having an enclosure having: a top wall; a bottom wall; at least one sidewall connecting the top wall to the bottom wall; an acoustic output opening; and a back volume defined by the top wall, the bottom wall and the at least one sidewall. A speaker driver is positioned within the enclosure, the speaker driver including a sound radiating surface having a top face and a bottom face for emitting sound waves therefrom. A frame member is attached to the speaker driver, the frame member forming a front volume chamber acoustically coupling the top face of the sound radiating surface to the acoustic output opening and a back volume chamber that overlaps a side of the speaker driver and acoustically couples the bottom face of the sound radiating surface to the back volume.
