Electronic device comprising speaker structure

An electronic device comprising:

• a first housing;
• a display disposed on a front surface of the first housing and extending in a first longitudinal direction and a second longitudinal direction which crosses the first longitudinal direction;
• a rear cover;
• a side structure that extends from the display to the rear cover;
• a first speaker that is provided in a space between the rear cover and the display, and is configured to emit sound through first holes and second holes that are formed through the side structure, wherein the first holes overlap the first speaker along the first longitudinal direction and the second holes are offset from the first speaker along the second longitudinal direction;
• a conduit comprising a first portion extending in the first longitudinal direction from the first speaker to the first holes and a second portion that is offset from the first speaker along the first longitudinal direction and is communicably connected to the first portion;
• an opening formed at an upper end of a rear surface of the first housing, offset from the first speaker along the first longitudinal direction and overlapping with the conduit when viewed in a direction perpendicular to the rear surface of the first housing, the opening being connected to the conduit;
• and
• an expansion portion connecting the conduit and the opening in the direction perpendicular to the rear surface of the first housing.
