8. A wearable electronic device comprising:

a housing at least partially defining an interior cavity divided into a first volume and a second volume, the first volume configured to receive water therein;

a processor positioned within the second volume;

an internal member dividing the first volume and the second volume and defining an opening; and

a speaker positioned within the first volume and at least partially over the opening in the internal member, the speaker and the opening cooperating to define an air-permeable water-blocking passage between the first volume and the second volume.

9. The wearable electronic device of claim 8 , wherein:

the opening is a first opening;

the housing defines a second opening; and

the second opening fluidly couples the first volume to an external environment.

10. The wearable electronic device of claim 9 , wherein:

the wearable electronic device comprises a mesh positioned over the second opening; and the mesh is configured to block contaminants from the external environment.

11. The wearable electronic device of claim 9 , wherein:

the housing defines a capillary passage fluidly coupling the first volume to the external environment;

the capillary passage is configured to draw liquid out of the first volume; and

a size of the second opening is larger than a size of the capillary passage.

12. The wearable electronic device of claim 11 , wherein:

the wearable electronic device comprises a band;

the housing defines a channel configured to couple to the band; and

the capillary passage extends from a first surface of the channel to a first internal surface of the first volume.

13. The wearable electronic device of claim 8 , comprising:

a transparent cover coupled to the housing;

a touch sensor positioned below the transparent cover and configured to detect touch inputs to the transparent cover; and

a crown positioned along a side region of the housing and configured to receive at least one of a translational input or a rotational input.

14. The wearable electronic device of claim 8 , wherein:

the wearable electronic device comprises a pressure-sensing component positioned in the first volume; and

the pressure-sensing component comprises:

a substrate;

a body coupled to the substrate, the substrate and the body cooperating to define a cavity; and

a force-sensitive element positioned on the substrate and within the cavity.

15. An electronic watch comprising:

a housing at least partially defining a cavity;

a display positioned within the cavity;

a barrier positioned within the cavity and separating the cavity into a first volume and a second volume; and

a speaker positioned within the first volume and defining an air-permeable water-blocking passage between the first volume and the second volume, the speaker configured to produce a sound output.

16. The electronic watch of claim 15 , wherein:

the speaker comprises:

a body;

a driver assembly; and

a diaphragm;

the driver assembly is configured to move the diaphragm to produce the sound output; and

the diaphragm is positioned over the air-permeable water-blocking passage and is configured to allow air pressure equalization between the first volume and the second volume.

17. The electronic watch of claim 15 , wherein:

the electronic watch further comprises a porous drain structure positioned within the first volume;

the porous drain structure fluidly couples the first volume to an external environment; and

the porous drain structure is configured to draw liquid from the first volume to the external environment.
