The loudspeaker is generally used for sound field excitation. In this paper, the loudspeaker was transformed into an inertial actuator to realize the active control of the vibrating plate. Firstly, the physical model of the loudspeaker as an inertial actuator was analyzed, and then the experimental research was carried out by using the decentralized multichannel speed of negative feedback control strategy. Lastly, the plate vibration was analysed by laser vibrometer. The results has shown that it is feasible to transform the loudspeaker into an inertial actuator for active vibration control, and the amplitude can be reduced by 43.4% at most. %K 扬声器,惯性作动器,振动主动控制,分散式控制,速度反馈
