Ah projects like these can be so frustrating because one has the hopes they'll be something fun and wild, but happen to be quite the opposite hahah Still, you made a great attempt and I applaud you for that
It's immediately obvious that your needle won't work. Most of the motion of the diaphragm will move the needle lengthwise, resulting in zero oscillation on the paper. You need to have a 90 degree lever for the needle to convert the diaphragm's vertical (lengthwise) movement to horizontal across the paper. Look at the Victrola guy's video, which shows a 90 degree pivot for his needle.
