Abstract:
An ultrasonic vibrator comprising:a transducer constructed by connecting a plurality of vibrating elements for converting a driving current into vibrations; an amplitude increasing portion for increasing an amplitude of a vibration of said transducer, said amplitude increasing portion having a horn at a front side thereof and a flange-shaped fixing portion at a base side thereof, said transducer connected to said flange-shaped fixing portion; a cover covering said transducer; a supporting/member for supporting and fixing said flange-shaped fixing portion and said cover in an airtight state by interposing a packing between said flange-shaped fixing portion and said cover; a lead wire for supplying said driving current to said plurality of vibrating elements; a partition member, disposed at the base side of said transducer, for defining a first chamber for passing said lead wire in an airtight state and containing said transducer in said cover in an airtight state; a member, fitted to a base side of said cover in an airtight state, for defining a second chamber for passing an electric power supply cord in an airtight state and drawing said electric power supply cord into said cover between said partition member and said member; and a plug for connecting said electric power supply cord to an electric power for generation of said driving current.
