The invention discloses a connecting member device used for suppressing low-frequency noise. The connecting member device comprises a base, one end of the base is provided with a barrel in a certain depth axially, the wall and the bottom of the base are provided with through holes in various directions, the through holes include first through holes, second through holes and third through holes, the first through holes penetrate the wall and the bottom of the barrel along the first direction and are arrayed, the second through holes penetrate the wall and the bottom of the barrel along the second direction and are arrayed, and the third through holes penetrate the wall and the bottom of the barrel along the third direction and are arrayed. Damping rods are inserted into the through holes, vibration energy transmitted from a connecting part to a connected part can be absorbed, and noise can be suppressed. Horizontal and vertical vibration transmitted from the connecting position can be isolated, so that the horizontal and vertical vibration waves are dissipated and filtered after passing the damping rods in the base of special cavities, and good damping effect can be achieved within the low frequency domain. By the connecting member device, vibration energy transmitted from the connecting part to the connected part can be effectively absorbed, and vibration intensity is reduced.
