My understanding of how microphones work is that they’re the same as the eardrum. Basically a flat surface (like the skin of a drum) is blasted by sound waves (which aren’t ‘up and down’ waves, they’re ‘in and out’ waves). On the other side, a sensor detects the vibrations on the drum and then converts them to electrical signals representing sounds. There’s no hole that water could get into, the sensor is a flat surface.
But you might want to wait for someone who knows what they’re talking about to come along
Microphones (& speakers) generally do consist of a thin membrane that vibrates a coil over a permanent magnet, which in turn produces an electrical signal that can be translated to sound again.
If that membrane is made of a watertight material, and all the possible gaps around are properly sealed, there’s nowhere the water can enter.
