The utility model relates to the technical field of interventional ultrasound, and discloses an ultrasonic assembly emitting multiple sound beams in opposite directions. The ultrasonic assembly comprises a first ultrasonic energy transducer and a second ultrasonic energy transducer, wherein the lower surface of the first ultrasonic energy transducer ad the upper surface of the second ultrasonic energy transducer are plated with a metallic coating, a common metallic coating is plated between the upper surface of the first ultrasonic energy transducer and the lower surface of the second ultrasonic energy transducer, or the upper and lower surfaces of the first and second ultrasonic energy transducers are plated with metallic coatings. A back sheet is arranged between the metallic coating of the upper surface of the first ultrasonic energy transducer and the metallic coating on the lower surface of the second ultrasonic energy transducer. Metallic belt is connected on the same side of each layer of the metallic coating, and the tail end of each metallic belt is respectively connected to an electrode wire coaxial to the metallic belt. The ultrasonic assembly reduces acoustic energy loss, improves electroacoustic conversion rate and work efficiency and saves installation space.
