<p>An acoustic transducer and method for driving same. A flat or somewhat curved panel has one or more drive motors at selected locations to generate transverse waves in the panel and concomitant longitudinal acoustic waves in an acoustic medium in which the panel is disposed. It also has attenuation features, such as damping or active wave cancellation motors, at one or more boundaries to substantially attenuate or essentially cancel arriving transverse waves and the reflections they would otherwise produce, thereby creating virtual infinite panel boundaries and reducing or substantially eliminating unwanted modes and wave interference in the panel. A linear motor is provided for driving one or more edges of the panel.</p> |
