Abstract
The invention relates to a force generator (10a) for mounting on a structure (12) in order to introduce vibrational forces in a controlled manner into said structure for affecting vibrations, comprising at least one spring arm (14) on which a flexural arm (22) having an inertial mass (24) and extending in the direction toward the attaching point is fastened, and having at least one piezo transducer (26) at both ends (16, 18) of the spring arm (14), wherein the center of gravity of the inertial mass (24) is disposed in the region of the center of the spring arm (14). Alternatively, two guide springs are disposed on both sides of the spring arm (14) parallel thereto, in order to generate a vibrational motion, wherein the fastening point of the flexural arm (22) comprises an unchanged orientation during the vibrational motion.
