Claim 16:
17. An electronic device, comprising:
a housing;
a cover coupled to the housing to define an internal volume, the cover defining a surface of the electronic device and configured to move toward the housing in response to an increase in pressure on the front cover; and
a seal extending along a perimeter of the cover and coupling the cover to the housing, the seal configured to compress in response to the cover moving toward the housing, wherein:
in response to a first external pressure, the seal is configured to exhibit a first level of air-permeability configured to equalize a first pressure within the internal volume with a second pressure of the external environment; and
in response to a second external pressure, greater than the first external pressure, the seal is configured to exhibit a second level of air-permeability that is less than the first level of air-permeability.
