The invention discloses a novel vibration reduction device based on Stewart configuration, and relates to the technical field of vibration reduction. The novel vibration reduction device comprises anupper platform, a lower platform and a plurality of single-leg vibration reduction units. Every two adjacent single-leg vibration reduction units are connected with the upper platform and the lower platform in a spatial and orthogonal manner to form a cube structure vibration reduction platform. The cubic Stewart spatial configuration is adopted to solve the problem that decoupling is difficult, so that the stable connection between sensors such as a hydrophone and the basic working face can be guaranteed, the displacement transmission rate of the hydrophone can be effectively reduced, the displacement transmission rate is smaller, the natural frequency of low-frequency vibration reduction is lower, the low-frequency vibration isolation performance is better, the foundation vibration of the sensors can be reduced
