Modified piezoelectricity wafer formula ultrasonic transducer

The utility model relates to a transducer structure aims at providing a modified piezoelectricity wafer formula ultrasonic transducer. This transducer includes the potsherd and the electrode slice of multiunit interval arrangement to and locate the back shroud and the front shroud at both ends from beginning to end, the prestressing force screw rod passes its center, back shroud, potsherd and electrode slice are the annular structure that the size is unanimous, be equipped with the breach on back shroud and potsherd, establish the welding position that supplies the voltage input cable to insert on the electrode slice surface that breach department exposes. The utility model discloses under produced ultrasonic vibration intensity and traditional form transducer keep unanimous prerequisite, can reduce the cracked condition of electrode slice at to a great extent. Through adopting ring form electrode slice, the great projection scope that has reduced the electrode slice makes protecting sheathing's design and application range more nimble. Improve the area of electrode slice welding position, consequently increased the intensity at this position, greatly reduced the probability that the electrode slice fracture takes place.
