The invention provides an acoustic bridge device for transmitting vibration of a second acoustic channel of a mechanical system. The acoustic bridge device comprises a support, a frame type cross beam and an elastic suspension rod. The support comprises a set of supporting columns and a set of cable-stayed reinforcing rod structures matched with the supporting columns, the frame type cross beam comprises a set of transverse beams, longitudinal beams and anti-bending reinforcing beams, and the transverse beams and the anti-bending reinforcing beams are rigidly connected with the longitudinal beams respectively; the elastic suspension rod comprises a group of suspension rods, an elastic suspension element and a pipeline elastic horse foot interface, and the suspension rods are arranged below the frame type cross beam and are elastically connected with the lower surface of the frame type cross beam through the elastic suspension element; the end face and the side face of the tail end of the suspension rod are respectively provided with an installation connector of the pipeline elastic horse foot in a reserved mode. According to the technical scheme, vibration interference of the second sound channel of the ship mechanical system on the first sound channel can be eliminated, and technical support is provided for accurate evaluation of the vibration control effect of the first channel of the mechanical system.
