This application provides a hard drive backplane assembly and an electronic device. The hard drive backplane assembly includes a hard drive backplane and an expansion cavity muffler. The hard drive backplane has a plurality of ventilation holes, and the expansion cavity muffler is mounted in the ventilation holes of the hard drive backplane. The expansion cavity muffler includes at least one expansion cavity and at least one connecting pipe in communication in a first direction. The connecting pipe at one end of the expansion cavity muffler facing toward the hard drive backplane is fixedly mounted in the ventilation hole, so that the expansion cavity muffler is in communication with the ventilation hole. An area of a cross-section that is of each expansion cavity and that is perpendicular to the first direction is larger than an area of a cross-section that is of the connecting pipe adjacent to the expansion cavity and that is perpendicular to the first direction. The first direction is perpendicular to a surface of the hard drive backplane. The expansion cavity muffler can reduce impact of noise generated by a cooling fan on a hard drive, increase input/output operations per second of the hard drive, and ensure a heat dissipation effect of the cooling fan.
