The utility model discloses an ultrasonic transducer with an efficient damping module, which comprises an upper pressing piece, a first piezoelectric ceramic piece, a second piezoelectric ceramic piece, a third piezoelectric ceramic piece and a fourth piezoelectric ceramic piece. The upper surface of the second piezoelectric ceramic piece and the upper surface of the third piezoelectric ceramic piece are each provided with a second circular groove. The ultrasonic transducer with the efficient damping module is provided with a first damping gasket and a second damping gasket, so that when the ultrasonic transducer vibrates in the working process, the first damping gasket plays a role in protecting the upper surface of a first piezoelectric ceramic piece, and the upper surface of the first piezoelectric ceramic piece is prevented from being damaged due to collision of an upper pressing piece; and the second damping gasket plays a role in protecting the lower surface of the fourth piezoelectric ceramic piece, so
