PURPOSE:To provide a tool horn that can be used by even one point driving and can form an elongate machined band having the same phase and displacement, by combining a square bar that can produce flexure vibrations with vertical vibration resonators that can produce vertical vibrations. CONSTITUTION:A columnar vertical vibration resonator 15 has a vibration producing smaller surface 18 at one end, a machining wider surface 12 at the other end and a section located intermediate between the surfaces 18 and 12 and having a width intermediate between them is used as a unit. A plurality of such resonators 15 are arranged in a row. The vibration producing surfaces 18 of the resonators 15 are connected normally to the same phase loop points 5 of the vibrations of the square bar 16 that can resonate in a flexible manner as shown by a vibration displacement curve 3 in an integral mode at or over secondary mode, the other ends of the resonators 15 are connected to be made continuous, the side surface of the square bar 16 opposite the side surface where the resonatores are connected is to serve as vibration producing points, and the other side surfaces of the resonators 15 are to serve as a machining surface 12. |
