Occasional Vibration noise after toilet filled

[FandM]

Hi

I have an occasional noise from the toilet. The toilet is less than a year old and sometimes after the toilet finishes filling back up there is a vibration noise. It doesn’t happen all the time. Just wondering what this could be.
Thank you

If it’s a standard float valve it might be the washer. If it’s any other valve, then could be loose pipes or any number of things. Photo of said valve?

Hi this is the valve in the toilet

Could still be the washer, but could also loose pipes.
