Use tweezers to remove the four black rubber screw covers.

Use a Phillips screwdriver to remove four 8.9 mm screws underneath the screw covers.

Once all four screws are out, gently pull the black cover out using your hands or use a spudger to pry it out.

The cover is attached to the motherboard beneath by the speaker cable. Don't yank the cover from the device. You will need to detach the connector from the socket before removing it entirely.
