We report on acoustic impedance control of the acoustic resonator using pneumatic balloon actuators. The fabricated pneumatic balloon actuators at acoustic holes could tune the acoustic resistance and the inertance of the resonator through structural parameter control. This paper focuses on the tuning of the acoustic resistance and the inertance when the acoustic capacitance is fixed. We tried to control not only the resonant frequency but also the total acoustic impedance and the phase. In the experimental results, a slight deformation of actuators could provide a large change of the acoustic impedance in the resonator.
