摘要：

A thin and flexible transducer design for use in air is described. It is fabricated from three or more layers of material to form an electrostatic device with many interesting properties. The new acoustic source has an excellent high-frequency response and can be used as an acoustic radiator over a wide range of frequencies, in both the audible and ultrasonic frequency ranges. The frequency response and directivity are both modeled and compared to theory, where it is demonstrated that the device operates in a manner consistent with a plane piston source.
