Abstract
First and second units have similar, preferably substantially identical, constructions. Each unit is preferably cylindrical and has an outer electrically conductive shell preferably made from a metal. A dielectric material, preferably a ceramic, abuts the inner surface of the electrically conductive shell in each unit. A conductive coating is disposed on the inner surface of the dielectric material in each unit. In this way, each unit defines a capacitor with the shell and the conductive coating constituting the capacitor plates. The shell and the dielectric material in each unit have axially extending openings of matching dispositions. The units are disposed in abutting relationship with the openings facing each other. An alternating voltage is applied between the conductive coating and the conductive shell in each unit. This causes current to flow through the capacitor in each unit and to produce vibrations of the shell and the dielectric material in each unit. Because of the bracing provided by the bonding of the two (2) units, the units are inhibited from breaking as a result of the vibrations. Furthermore, the units are able to respond to voltages of increased amplitude, thereby increasing the intensity of the vibrations. The bonding of the units also inhibits vibrations of the units in undesirable directions and concentrates the vibrations in a particular direction providing optimal benefits.
