Good luck with the self powering part. You would need to buffer at least some of the energy, because sometimes there are pauses, see e.g. at 0:45:

and power could be a problem for a speaker. Also forward/backward movements are possible, see at 2:13 and 3:47, and faster movements sound different, see 2:53:

so you should measure the speed and direction of the crank.
