Abstract
The vibration control device comprises an electromechanical transducer module adapted to be attached to an outer surface of a panel member, and a control circuit for electrically controlling an internal stress of the electromechanical transducer module so that the internal stress counteracts a stress of the panel member resulting from a vibration of the panel member that is desired to be controlled. Thus, the stress produced from the vibration of the panel member is transmitted to the electromechanical transducer module, and is converted into an electric energy. The electric energy thus produced by the vibration of the panel member is applied to the electromechanical transducer module, and is thereby converted into an internal stress of the electromechanical transducer module which counteracts the vibration of the panel member. Therefore, the rigidity of the panel member against vibration can be increased in effect, and, in particular, the resonant vibration of the panel member can be effectively controlled as well as other vibrations of the panel member arising from various sources.
