    Abstract: Noise reduction is the major issue in the
loudspeaker for the application of the musical instruments
and related areas. In this study, a noise disturbance control
of a loudspeaker with optimal and robust controllers has
been done successfully. The noise of the loudspeaker has
been analyzed by simply track a reference cone
displacement with the actual cone displacement. Static
output feedback and H∞ optimal loop shaping controllers
have been used to compare the actual and reference cone
displacements by using a sine wave and random cone
displacement signals and a promising results have been
analyzed.
