To all the electronic nerds out there: I am trying to trigger a 555 timer by movement in a random direction that also occurs randomly and any change in position should trigger the 555. AFAIK tilt switches are not useable here. Does this idea make sense?

Ferrite core In orange, spool in blue.

Would there be a voltage generated by movement if the core is suspended by some kind of spring or rubber band?

The idea being to play a sound from a df mini player by pulling a pin high for 3 seconds.

    I haven’t done a course in electromagnetism yet, but as far as I understand, the ferrite core is just a piece of metal with no magnetic field, so moving it doesn’t induce a voltage

    I think it would, however, change the inductance, just like the iron core in a transformer does
