Although "Helmholtz resonator" is often used to describe a broader range of resonators than Helmholtz's original design, I think it's dubious to call fipple flutes "Helmholtz resonators". The fipple mechanism sets up an oscillating sheet of air going into and out of the pipe, which isn't present in traditional Helmholtz resonators. See:

I think a better definition of a flute is a mouth-blown wind instrument with no vibrating parts.
- IggleSniggle 2y agoSuperb correction, thanks!
- mrob 2y agoI just remembered there are East Asian flutes that use vibrating membranes to modify the sound: https://en.wikipedia.org/wiki/Dizi_(instrument) https://en.wikipedia.org/wiki/Dizi_(instrument) https://en.wikipedia.org/wiki/Daegeum https://en.wikipedia.org/wiki/Daegeum These are uncontroversially flutes, so the definition would have to be "mouth-blown wind instruments that generate a tone without using vibrating parts".
