Abstract
A panel audio loudspeaker includes a panel extending in a plane. The loudspeaker also includes an actuator coupled to one side of the panel and configured to couple vibrations to the panel to cause the panel to emit audio waves. The actuator includes a rigid frame attached to a surface of the panel, the rigid frame includes a portion extending perpendicular to the panel surface and a plate extending parallel to the panel. The actuator also includes a magnet assembly and a magnetic coil forming a magnetic circuit. The actuator further includes at least one flexible member connecting the magnetic circuit to the portion of the rigid frame extending perpendicular to the panel surface. The actuator also includes a compliant member positioned between the magnetic circuit and the panel, the compliant member being configured to increase output of the loudspeaker compared to the actuator without the compliant member.
