Abstract
An opening at a first carbon fiber sheet is provided, the opening extending through the sheet from a first major surface to a second major surface, the opening defining two sides and a first end of a rectangular flap, a second end of the flap remaining rooted in the first carbon fiber sheet. A piezoelectric transducer is bonded to the first carbon fiber sheet, the transducer proximate to the second end of the flap. A controller including a signal generator is coupled to the piezoelectric transducer, the piezoelectric transducer to excite sympathetic vibration of the flap.
