A wearable electronic device includes: a headphone including two sound generators and an elastic band connecting the two sound generators; a display part including two end portions and a middle portion located between the two end portions; and two movable members, wherein each sound generator is movably connected to the corresponding end portion of the display part via the corresponding movable member. Since the sound generator is movably connected to the end portion of the display part via the movable member, the end portion of the display part is not bent and deformed when the headphone is opened outward, such that the restoring force caused by deformation is not increased or even generated, thereby facilitating use of the user.
