Abstract
The present invention comprises a radially pulsating cylindrical surface operating as a wave transmission-line. The device is responsive to electrical means and may be practically utilized to generate pressure waves. A conventional electromagnetic driving system is employed with the novel cylindrical surface. A cylindrical voice coil is affixed to the cylindrical surface co-axially. The surface may comprise a matrix of helically oriented fibers suspended in an elastomeric impregnant. Damping means may be provided both internally and terminally. The radiation produced is omnidirectional.
