PROBLEM TO BE SOLVED: To provide a highly efficient speaker system capable of performing signal reproducing faithful to an input signal. SOLUTION: A speaker system is provided with a diaphragm 2 as a sound generating source, and a linear pulse motor 11 having a minimum moving unit and vibrating the diaphragm 2 at a quantized amplitude based on the minimum moving unit. The speaker system 1 reproduces the vibration of the diaphragm 2 faithful to an input signal by controlling the vibration of the diaphragm 2 at the quantized amplitude that the minimum moving unit of the linear pulse motor 11 is 1 bit and digitally driving the diaphragm 2.
