Abstract

Actuator for the active cancellation of vibrations in which an external housing 3 accommodates an electromechanical actuator 7 able to generate a secondary vibration a(t) which is added, with opposite phase, to a primary vibration n(t) undergoing the cancellation. The housing 3 also accommodates an accelerometer 20 able to detect the residual vibration r(t) produced by the interference between the primary vibration n(t) and the second vibration a(t) and an electronic computing centre 9 which receives at its input the signal from the accelerometer 20 and generates in response to this signal a control signal for the actuator 7. <IMAGE>
