Ground-state cooling of the mechanical resonator is an important premise for the quantum manipulation of macroscopic mechanical devices. We propose a scheme to realize the ground-state cooling of the magnomechanical resonator in a cavity magnomechanical system composed of a ferromagnetic sphere and two microwave fields. We demonstrate that the ground-state cooling can be achieved under the experimentally feasible parameters in the unresolved sideband regime. Due to the interaction between the magnon and the two microwave cavities, the double-passage quantum interference is generated. The spectral density of the magnetic force exerting on the magnomechanical resonator gets changed and then the heating process can be completely suppressed, thus the cooling rate is greatly increased in the unresolved sideband regime. Furthermore, compared to the cavity magnomechanical system with a single microwave field, this scheme has a great enhancement on ground-state cooling of magnomechanical resonator. The scheme provides potential applications in quantum manipulation of macroscopic mechanical systems beyond the resolved sideband limit.
