im doing a project with some pals and need to atleast understand how do these gens work, sorry for my english if any mistakes are found
edit: i think i wrote the question wrong…um im tryna understand how do vibrational generators generate electricity

Doing so in a way that generates a practical amount of power is… Involved. You’d be connecting a ton of tiny devices for the most part.
But there are multiple ways this can be done. The most common to encounter in daily life would be the piezoelectric effect. Which is a mouthful but basically certain materials, notably quartzes and specific ceramics and yes that plays into quartz movements in watches, will produce electricity when physical force is applied to them. In particular by applying pressure which you can do repeatedly with vibration. Gas stove starters, lighters with the trigger mechanism, things like that use this to generate a short lived spark.
You can also use deformation of a magnetized ferric material. Mouthful again, right? Basically if you change the shape of a magnetized hunk of metal the shape of the magnetic field around it changes, too. You can capture that change by wrapping it in a coil. In small sizes this isn’t really a valuable amount BUT some people are talking about incorporating BIG ones into things like the structure of high rise builds which have to flex and move anyway as passive generators.
There are a couple other ways to do it, ut that’s the one we use the most(piezo) and the one I’ve heard recent talk about (deforming a magnet)
