FIELD: printing equipment.
SUBSTANCE: invention relates to devices for protection of printed circuit boards from vibration action. Device of active vibration protection of electronic equipment consists of in-series electrically connected converter of mechanical energy into electric, charge amplifier, phase shifter and converter of electric energy into mechanical, the last of which is kinematically connected to plate, metal case. Plate is intended for attachment of electronic equipment and is made in the form of a printed-circuit board. Metal case is made in the form of a hollow rectangular parallelepiped, in which the elastic plate is installed so that it forms one of its faces. In the metal housing there is a converter of electric energy into mechanical one, which one side is fixed on the inner surface of the plate, and the other side is fixed on the inner surface of the base of the metal housing.
EFFECT: simplified design, which increases speed of operation, as well as high reliability of structure and noise immunity.
