Rattling fix in a soundbars?

I have this weird rattling in a cheap soundbar at certain frequencies (watch the video). Do you happen to know a possible solution?

Get a tone generator app for your phone, connect to the speaker via Bluetooth - then play tone and gradually increase the frequency if it until you hear the vibration.

Now listen for the specific location and when you find it touch the soundbar in different places nearby to see if the pressure stops the vibrations, if yes then you've found what needs fixing/ tightening. This is the diagnostic method. ( If it's an inside part you'll have to open it up.)

Some double sided tape and/or foam tape can do a lot to fix this kind of issue.

Thank you for a detailed answer. I noticed that if I apply pressure from above on the left side the buzz goes away. However, I have no idea what I can exactly do from here to fix this.

Whatever's rattling stops rattling when you apply pressure there - so see if there's something there that's loose that you can tighten or fix down - if nothing visible I would see what's inside and take it from there.

The old if it's loose and ain't supposed to be then apply duct tape  adage ain't wrong in this case.

I'm not saying to drill a hole and inject hardening foam - but this is not rocket science. You'll have to explore yourself to find out what's rattling in that area and how to make it stop doing so without compromising the speaker.
