1. An electronic device comprising:
a first housing structure;
a second housing structure disposed adjacent to the first housing structure;
a hinge structure disposed between the first housing structure and the second housing structure and configured to provide a rotational movement between the first housing structure and the second housing structure;
a flexible display extending from the first housing structure across the hinge structure to the second housing structure; and
at least one haptic actuator disposed inside or adjacent to the hinge structure,
wherein the at least one haptic actuator is disposed in parallel with a direction for a folding axis of the hinge structure to output a vibration corresponding to the folding axis,
wherein the vibration output by the at least one haptic actuator travels in a first direction perpendicular to the folding axis and has an amplitude in a second direction parallel with the folding axis,
wherein the first housing structure includes a first housing, and a first bracket that is at least partially covered by the first housing and rotatably coupled to a first side of the hinge structure,
wherein the second housing structure includes a second housing, and a second bracket that is at least partially covered by the second housing and rotatably coupled to a second side of the hinge structure,
wherein the hinge structure includes a plurality of hinges, and a hinge case covering at least one surface for each of the plurality of hinges,
wherein the electronic device further comprises a connecting plate including a first part coupled to a first end of the hinge case and the first bracket, and a second part coupled to a second end of the hinge case and the second bracket, and
wherein the vibration generated by the at least one haptic actuator pass through the hinge case and the connecting plate, the vibration is generated to move to the first housing structure and the second housing structure, and the vibration transferred to the first housing structure and the second housing structure is at least one of a frequency, a signal strength, and a signal phase.
