an opening positioned along the exterior surface, the opening fluidly coupling the first volume to an external environment; and

a speaker operably coupled to the processing system, the speaker defining an interface between the first volume and the second volume, the speaker configured to equalize a pressure between the first volume and the second volume.

9 . The electronic watch of claim 8 , wherein the housing further defines a capillary passage configured to draw liquid from the first volume to the exterior surface.

10 . The electronic watch of claim 9 , wherein:

the exterior surface of the housing defines a recess;

the electronic watch comprises a wristband defining an end configured to be positioned in the recess;

an interstitial volume is defined between the recess and the end of the wristband;

a capillary volume is defined by the capillary passage; and

the interstitial volume and the capillary volume together define a substantially uninterrupted drain volume.

11 . The electronic watch of claim 8 , wherein:

the exterior surface of the electronic watch is a peripheral side surface of the electronic watch; and

the opening is formed through the peripheral side surface of the watch.

12 . The electronic watch of claim 8 , wherein:

the electronic watch comprises an internal member positioned between the first volume and the second volume, the internal member defining an opening fluidly coupling the first volume to the second volume;

the speaker comprises a diaphragm;

the speaker is coupled to the internal member; and

the diaphragm and the internal opening define an air-permeable passage between the first volume and the second volume, the air-permeable passage configured to equalize pressure between the first volume and the second volume.

13 . The electronic watch of claim 8 , wherein the electronic watch further comprises a mesh spanning the opening and configured to block contaminants from entering the first volume.

14 . The electronic watch of claim 8 , wherein:

the speaker is configured to produce a sound output; and

the sound output is configured to eject liquid from the first volume via the opening.

15 . A wearable electronic device comprising:

a display;

a housing coupled to the display, the housing comprising a sidewall, the sidewall defining:

an opening having a first diameter;

a capillary passage having a second diameter less than the first diameter; and

an internal cavity fluidly coupled to an external environment via the opening and the capillary passage; and

a speaker at least partially defining a sub-chamber within the internal cavity, the sub- chamber liquidly sealed from the internal cavity.

16 . The wearable electronic device 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 a sound output; and
