In the third embodiment of the present invention, when the maximum outer diameter R of the flange 3 is 20mm to 40mm, the number of the receiving grooves 31 and the number of the bosses 5 are both 6.
In an embodiment of the present invention, the cross section of the boss 5 is semicircular/rectangular along the radial direction of the elastic damping ring 4 and perpendicular to the central axis of the transducer 2.

According to the resonance principle, the amplitude of the vibration along the longitudinal direction at the vibration joint surface of the transducer 2 is minimum, so that the occurrence rate of vibration energy leakage caused by the excessively strong longitudinal coupling effect between the flange 3 and the sealed shell 1 can be effectively reduced. According to the poisson's ratio relationship of the elastic material, when the amplitude of the longitudinal vibration is minimum, the amplitude of the expansion-contraction vibration along the radial direction is maximum, so that a certain degree of vibration energy still leaks through the radial coupling effect. According to the invention, by arranging the annular leakage reduction groove 6, the contact area between the flange 3 and the transducer 2 is reduced, and the vibration frequency at the peripheral edge of the flange 3 is reduced, so that the radial coupling effect between the transducer 2 and the sealed shell 1 is effectively reduced.

The inner diameter of the sealed shell 1 is larger than the inner diameter of the transducer 2, so that the inner wall of the sealed shell 1 is not in contact with the transducer 2, and the sealed shell 1 is prevented from directly generating bad interference on the vibration of the transducer 2.
