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.

A duty correction device includes a clock generation circuit, first and second correction pulse generation circuits, and a duty correction circuit. The clock generation circuit generates first to third divided clock signals, each having a phase offset from a reference clock signal. The first correction pulse generation circuit generates a first correction pulse by detecting a phase difference between a delayed clock signal and the first and second divided clock signals. The second correction pulse generation circuit generates a second correction pulse by detecting a phase difference between the second and third divided clock signals. The duty correction circuit checks whether the first and second correction pulses are generated at a preset logic level of the reference clock signal, and reflects the first or second correction pulses in a duty correction operation for the reference clock signal according to a result of the check.
