Abstract
A speaker system includes a first driver unit, a second driver unit and a cylinder case. The first driver unit and the second driver unit are disposed face to face with the same axial line. The axial line of the first driver unit and the axial line of the second driver unit forms a coaxial axial line or parallel axial lines. The cylinder case is hollow. The first driver unit and the second driver unit are disposed inside the cylinder case and contacts the inner wall of the cylinder case so that the central axial line of the cylinder case is parallel to the coaxial axial line or the parallel axial lines. A speak device includes a plurality of speaker systems. By the aforementioned configuration, even driver units may be disposed in a common cavity.
