The invention discloses an active vibration control device and a vibration control method. Specifically, a signal generator generates a vibration signal, the vibration signal is transmitted to a poweramplifier for power amplification and then transmitted to a first vibration exciter, the first vibration exciter drives a vibration damper to conduct vibration excitation back and forth, and a vibration source similar to vibration of an engine is generated; an acceleration sensor converts the vibration source into a vibration signal which is the same with a vibration signal of the engine; a capture card collects the vibration signals and transmits the vibration signals to a control module, the control module conducts PID adjustment on the received the vibration signals to obtain a signal which is the same with the vibration signals in frequency and reverse with the vibration signals in direction, and the signal is output to a second power amplifier and subjected to power amplification; asecond vibration exciter receives the amplified signal and generates an excitation force which is the same with the vibration source in cycle and reverse with the vibration source in direction; and the excitation force is acted on the first vibration exciter. The active vibration control device and the vibration control method have the advantages of being low in cost, simple in structure, capableof achieving active adjusting and controlling, wide in control range, high in precision and the like.
