Active mixer for reducing vibrations in mechanical structure of car, has main body containing movable mass, and guiding unit arranged between external periphery of mass and body, where body and fixing plate are formed integrally

摘要

The mixer has a cylindrical movable mass (M) linearly self-relocated in reciprocating motion along given displacement direction. A main body (11) contains the mass. A guiding unit (12) is arranged between an external periphery of the mass and the main body, and comprises a stage fixed at the mass. A fixing plate (9) and the main body are formed integrally. The mass comprises an upper magnetic structure (1), a lower magnetic structure (3) and a coil (2), and is placed around a ferromagnetic core (10). A cap (6) is fixed on the main body to lock up the mass in a sealed manner. The mass is balanced around a main axis.
