The present invention relates to a pulsating wave transducer including a base plate engaged with the outer circumference of a discharge port having a downwardly inclined exit to discharge a powder; a case having a hexahedral shape with an opened bottom and coupled to the base plate to close an internal space; a core frame having a closed hexahedral shape positioned in the internal space between the base plate and the case, with wing portions protruding from both sides of the hexahedral body; a core housed in the core frame and generating a pulsating wave in response to an electric signal; and a spring coupled to wing portions of the core frame to simultaneously perform a hitting function and a damping function, with one end being coupled to the base plate. The core frame is supported by the spring, and the bottom of the core frame is spaced apart from the base plate to protect the core housed in the core frame. Since the powder positioned around a chute, a hopper, and a transfer line is crushed and dispersed, absorption or aggregation of the powder in the discharge port is prevented, thereby preventing the inclined discharge port from becoming narrow or being clogged. Since the flowability of the equipment is improved and maintained, the powder can be smoothly transferred and supplied from the equipment to the transfer line. The transducer can be simply applied to a conventional equipment at low costs, as well as new equipment. The hitting and damping action of the discharge port discharging the powder can be simultaneously carried out. |
