Why does the sound on the laptop rattle at high volume?

Question

laptops

Notebook Asus N76VB, if I make the sound above average, the rattling starts. Tried reinstalling the driver. There is no rattle in the headphones. A month ago I handed over the same model to the store due to rattling. Today I bought the same one again, and in another store, but the rattling still takes place.
Moreover, not on all tracks, rattling is especially pronounced, for example, on similar tracks Denis A - Cuba (Robert Babicz sunshine mix) at the very beginning of the track, it especially rattles, but what is remarkable at low frequencies is an almost clear sound.
Both left and right speakers rattle. Help pliz, maybe it's in the gland? And then I think I should return this laptop, although I don’t want to, I really like the model, and in the reviews on the same Yandex market they write that the sound is perfect for this model.

Resonance can ...
You can put a simple sound generator and turn the frequencies at high power. It will be clear, the driver is cracking. or from the body. But most likely from the case, or the speaker itself resonates.
