Will it affect if the mobile hard disk and the small stereo are put together?

Based on the above conditions, it will not affect the mobile hard disk, and the mobile hard disk has anti-magnetic function, so that a little magnetic force will not affect the mobile hard disk at all.

Hard disk design protection

In the design of hard disk, the magnetic field lines are tightly wrapped around the disk, and basically do not overflow to the outside of the hard disk shell. Moreover, the hard disk shell is metal, which will also shield the external electromagnetic interference, so there is basically no magnetism outside the hard disk shell.

Excessive magnetic force will affect the hard disk.

It should be noted that when the magnetic force reaches a certain level, it will have a great impact on the mobile hard disk, damage the index track on the disk, and the computer can't read the data, and it will crash when plugged in.

It doesn't matter much if the voice is small.

In short, the small stereo has little effect on the hard disk, but it is recommended not to put it together.
