Hi @imats0up
Here's the ifixit [guide|112412] guide, that may help.
The [https://www.polartech.com.au/products/samsung-galaxy-note-9-loud-speaker-buzzer-ringer?variant=41121698218165¤cy=AUD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&utm_campaign=gs-2021-11-12&utm_source=google&utm_medium=smart_campaign&gclid=EAIaIQobChMInb_Q6ez-9gIVQYNLBR38Uwc6EAQYASABEgLjAfD_BwE|loudspeaker], if this is what you mean, can be seen in Step.13 of the guide. (supplier example only to show part)
Unfortunately it doesn't show how to remove it.
Hopefully this is of some help.
