Abstract
A split-ring or split-cylinder transducer in which a full or partial boot covering a shell is caused to be looped into the gap of the shell so that outward radial movement and circumferential expansion of the shell causes the boot to also move outwardly thus reinforcing the sound wave generated exterior to the shell of the transducer.
