Abstract
An audio system includes an audio panel. The audio panel includes a first face plate, a second face plate, and a core that includes a plurality of structural members that extend between the first face plate and the second face plate. The plurality of structural members define a plurality of cavities in the core. The audio system also includes a first piezoelectric actuator mounted to at least one of the first face plate, the second face plate, and the core. The first piezoelectric actuator is configured to convert electrical signals into mechanical energy to cause the audio panel to generate sound.
