An electronic device having openings covered by a vent assembly is disclosed. The vent assembly may include multiple adhesive layers surrounding an air-permeable, liquid resistant membrane that allow air to flow into and/or out of the electronic device, while also preventing liquid ingress into the electronic device. The membrane may be supported by several structural elements. For example, the vent assembly includes an adhesive layer secured with the membrane, with the adhesive layer including a web region having multiple ribs that engage the membrane. Also, the vent assembly includes a mesh material that includes a porous region that receives a portion of the adhesive layer. Also, an additional vent assembly may cover an additional opening of the electronic device and provide protection for an operational component in the electronic device. The additional vent assembly may allow air into the additional opening for the operational component.

The electronic device of claim 2, wherein the first adhesive layer includes a first stiffness, and wherein the second adhesive layer includes a second stiffness greater than the first stiffness. 4. The electronic device of claim 2, wherein the first adhesive layer includes a first adhesive strength, and wherein the second adhesive layer includes a second adhesive strength less than the first adhesive strength. 5. The electronic device of claim 2, wherein the operational component comprises a microphone. 6. The electronic device of claim 1, wherein the membrane comprises polytetrafluoroethylene. 7. The electronic device of claim 1, further comprising a bracket positioned in the enclosure and aligned with the through hole, the bracket adhesively secured with the vent assembly via the first adhesive layer. 8. The electronic device of claim 1, wherein the a second opening includes a size and shape in accordance with the first opening. 9. An electronic device, comprising: an enclosure having a through hole; anda vent assembly carried by the enclosure, the vent assembly capable of preventing liquid ingress into the through hole, the vent assembly comprising: a first adhesive layer that secures with the enclosure, the first adhesive layer having an opening,a membrane secured with the first adhesive layer and covering the opening and the through hole, the membrane having a material that permits airflow through the membrane while preventing the liquid ingress, anda second adhesive layer secured with the membrane, the second adhesive layer comprising a web region that supports the membrane. 10. The electronic device of claim 9, further comprising a mesh material that combines with the second adhesive layer, wherein the second adhesive layer includes: a first surface adhesively secured with the membrane, anda second surface adhesively secured with the mesh material, the second surface opposite the first surface. 11. The electronic device of claim 10, wherein the mesh material comprises a porous region, and wherein the second adhesive layer is at least partially embedded in the porous region. 12. The electronic device of claim 9, wherein the web region comprises: a first adhesive rib; anda second adhesive rib, wherein the first adhesive rib and the second adhesive rib define a second opening that allows the airflow, received by the membrane, to pass through the second adhesive layer. 13. The electronic device of claim 9, further comprising a third adhesive layer that secures with an additional component, wherein the mesh material includes: a first surface adhesively secured with the second adhesive layer, anda second surface adhesively secured with the third adhesive layer, the second surface opposite the first surface. 14. The electronic device of claim 13, wherein the additional component comprises a support layer secured with the third adhesive layer. 15. The electronic device of claim 9, wherein the first adhesive layer further comprises: a second opening; anda rib separating the opening from the second opening.
