Abstract: An electronic device having a speaker device. The electronic device may include a housing, a speaker device disposed inside the housing, and a sound generation circuit electrically connected to the speaker device. The speaker device may include a sound generation plate movable in a first direction, and a sound reflection construction facing the sound generation plate to form a space between the sound generation plate and the sound reflection construction. The sound generation plate includes a first surface disposed substantially at a center of the sound generation plate, the first surface having a convex shape when viewed from inside the space, and the sound reflection construction includes a second surface substantially aligned with the first surface along an axis of the housing, the second surface having a concave shape when viewed from inside the space.
