I dont know why i never thought to ask this before, but will my speaker magnet fry the NB or its memory card if they are too close?

My Chassis design has speaker mount v5,

Followed immediately by a NB/18650 chassis disk.

Im capable of putting a 1/4 inch spacer between the mount and the disk if that helps, and i know that accessing my sd card will be tough after final install, but i hadnt thought to ask if the speaker can be that close to the sd card. I havent seen any threads about it, so i assume its not an issue. At the same time, i dont want to assume incorrectly and ruin something.

I appreciate any insight.
