Claims (9)

1 . An apparatus for detecting sound waves, the apparatus comprising:

an air-permeable membrane that is waterproof;

a stainless-steel washer adjacent to the air-permeable membrane;

a mesh laser-welded to the washer that covers an aperture defined by the washer, wherein the aperture of the washer is positioned between the mesh and the air-permeable membrane; and

an adhesive coupled to a face of the washer distal from the air-permeable membrane and configured to secure the washer to a housing.

2 . The apparatus of claim 1 , wherein the air-permeable membrane is configured to act as an acoustic diaphragm that relays sound waves by vibrating when struck by sound waves.

3 . The apparatus of claim 1 , wherein the air-permeable membrane is waterproof up to at least about 5 atm.
