Abstract
The horn includes an outer cylinder and an inner shaft connected by a disk. The shaft has an axial input end, and receives vibrational energy at the axial input end and transmits the vibrational energy to the cylinder. The cylinder is hollow and has an inner surface, an outer surface, and first and second opposing end surfaces. The second end surface serves as a welding surface which applies vibrational energy to an object. The welding surface moves with the application of vibrational energy to the input end of the shaft. The disk portion connects the inner shaft to the cylinder and transmits the vibrational energy from the inner shaft to the cylinder.
