Abstract
A large area PVDF corrugation film air transducer is proposed. The transducer features large area and a high power output and a sharp beam angle. The vibration phase of convex section is shifted 180 degrees off from the concave section. These waves add constructively to form a strong acoustic beam when corrugation height is approximately half of the wavelength
