ELECTRO-AERO-ACOUSTIC SOURCE AND SYSTEM FOR ACTIVE NOISE CONTROL

摘要

The invention concerns an electro-aero-acoustic source (2), set in a flow (V) or beside a flow, consisting of electrodynamic or electromagnetic motor means (5) generating a reciprocating motion, and a member (3) coupled to the motor means (5), and obstructing the flow so as to exert a dynamic action on said flow. Said source can be used to produce an electro-aero-acoustic system for active noise control, in particular in a confined flow.
