Or - if you want to go one step more down that rabbit hole...
Use a software controlled switch to flip the 2nd speaker into a microphone. Electrically a speaker and a mic are essentially the same thing - especially when you get down to the scale of embedded speakers.
Then you just need an 'audio duct' to migrate the sound from the speaker & speaker/mic through the lid and around the screen. Otherwise known as a pocket lint trap.
