An electronic device comprising:

• a housing that includes a first plate, a second plate disposed on a side opposite to the first plate including an opening, and a lateral member at least partially surrounding a space between the first plate and the second plate;
• a display disposed in the space, wherein at least a part of the display is visible through the first plate;
• a third plate exposed through the opening and including a first through-hole;
• a printed circuit board disposed in the space and including a second through-hole at least partly overlapping the first through-hole when viewed from above the third plate;
• a microphone on a surface of the printed circuit board facing away from the third plate, wherein the microphone at least partly overlaps the second through-hole when viewed from above the third plate;
• a seal member that is disposed between the third plate and the printed circuit board around the first through-hole or the second through-hole;
• a support member including a first portion, which faces the surface and includes an opening penetrated by the microphone, a second portion that extends from the first portion in a first direction and faces the third plate, the second portion having a thickness in a second direction perpendicular to the first direction greater than a thickness of the first portion, a third portion that extends from the second portion in the first direction, and a looped fourth portion that extends from the second portion in the second direction to be disposed between the second plate and the third plate;
• a first fixture that is disposed between the surface and the first portion;
• a second fixture that is disposed between the third plate and the second portion;
• and
