Bending wave acoustic panel

摘要

A bending wave panel loudspeaker with a bending wave acoustic panel that is capable of supporting bending wave vibration. The panel has a front face and a rear face, and a transducer mounted on the panel to excite bending wave vibration in the panel in response to an electrical signal applied to the transducer so that sound energy is radiated from both the front and the rear faces of the panel. An acoustically porous resistive structure is mounted proximate to one face of the panel to resistively impede sound energy radiated from that one face.
