Abstract: A flexible display device is disclosed. The flexible display device may comprise a first body, a second body, a flexible display, a first microphone, a first cavity and a first variable cavity. The first variable cavity is formed to extend from the first cavity and have a volume that varies when the second body moves with respect to the first body. When the second body moves with respect to the first body, the volume of the first variable cavity changes so that resonance frequencies in the first cavity and the first variable cavity can vary. By using the first variable cavity, the sensitivity of the first microphone can be improved and the state of the flexible display device can be identified.
