How do earbuds deliver deep bass frequencies with such tiny drivers?

Question

Usually when you have a smaller speaker, you sacrifice the low end, but earbuds seem to manage to deliver substantial bass nonetheless. I assume the proximity to the eardrum helps, but I don’t fully understand how.

Your ear canal generates the bass. Take a small speaker and place it in a corner of your room. Notice how the bass arrives.
