Patent attributes
A transducer system includes a panel having one or more piezo-electric enabled foils and an arrangement of electric contacts coupled to the panel. The one or more piezo-electric enabled foils and the arrangement of electric contacts define a plurality of transducers thereon. Each transducer is associated with a respective region of the panel and with at least two electric contacts that are coupled to at least two zones at that respective region of the panel. The electric contacts are adapted to provide an electric field in these at least two zones to cause different degrees of piezo-electric material deformation in these at least two zones and to thereby deform the respective region of the panel in a direction substantially perpendicular to a surface of the panel, and to thereby enable efficient conversion of electrical signals to mechanical vibrations (acoustic waves) and/or vice versa.
