摘要

Acoustic device for locating faults, faults or abnormal vibrations in engines and machines in general, consisting essentially of a box formed by two coupled bodies, between which is contained an elastic membrane of which is attached a rod or rod that emerges at the outside, of adequate length, intended to be in contact with the part to be examined, transmitting its vibrations to the aforementioned membrane that will amplify them, leaving the box containing this membrane on the opposite side with a handle or handle, which remains attached a flexible tubular prolongation that, by means of a suitable connection, bifurcates into two other tubes joined to the respective ones of a head of constitution analogous to that of the stethoscopes, allowing to be coupled to the ears of the user.
