Abstract: An electronic device is disclosed including a housing including an outer wall, an inner, and a first through hole formed in the inner space, an audio module located in the inner space, a support structure located in the inner space between the audio module and the first through hole and including a second through hole; and a waterproof structure located in the inner space between the support structure and the outer wall including a flexible gasket. The gasket may include an outer rim, a recess portion moveable between the first through hole and the second through hole, and a connection portion between the rim and the recess portion, including at least one opening around the recess portion, such that the opening and the second through-hole form a sound path between the audio module and the first through-hole in the absence of pressure from an external liquid.
