Abstract: A flexible electronic device includes: a sensor; a flexible display; a piezoelectric speaker including N piezoelectric films attached to the flexible display; and a processor configured to: detect a change of a state of the flexible display through the sensor; based on the change of the state of the flexible display, determine locations of a number of piezoelectric films through which sound is to be output, among the N piezoelectric films; and output sound through the number of piezoelectric films by controlling the piezoelectric films to be activated, based on the determined locations of the number of piezoelectric films.
