Then why continue with this on the 13" topic ?? and you did ask what the input cover is so people will respond to the 13" as in title etc.
If you’re only getting the rattling / buzzing / resonance on one side, consider yourself lucky.
I get it from left and right…at difference frequencies. 85Hz-ish, 160Hz-ish, and 440hz-ish on the left. The right side seems to be a anything between 100 to 380Hz-ish…almost as if multiple components resonating at different frequencies. Kinda like a left → right resonance crossover.
So is it the speaker itself is blown or rattling against its own mounts? Or is the speaker somewhat loose, touching the keyboard above it when the case is fully assembled and resonating against the keyboard?
Anything that resonates at the same frequency as the test tone or at a harmonic of it could be sympathetically vibrating. Wondering how much of a peak there is on a frequency response sweep at those frequencies.
After working with Framework support to resolve the issue, they sent a new input cover. After installing it, the buzzing is gone completely in all frequency ranges. Videos of people talking in the affected ranges also are no longer hard to understand. I am surprised how much of an improvement it made just by replacing the input cover. Additionally, the touchpad on the new input cover feels much better than my original. The original was slightly loose and I just thought that’s how it was (and yes I did attempt to tighten it up).
For those who have issues, try working with support to get a new input cover! Now I just need to figure out how to transfer my dbrand skin…
