    Abstract: A display device includes: a display panel; a first sound generator on a first surface of the display panel, the first sound generator being configured to vibrate the display panel to output a first sound; and a second sound generator configured to output a second sound. A third sound is a sum of the first sound and the second sound, and a sound pressure level of at least one of harmonic tones of the third sound is less than a sound pressure level of at least one of harmonic tones of the first sound.

    Abstract: A display device includes: a display panel; a first sound generating device disposed below the display panel, where the first sound generating device generates a sound by causing the display panel to vibrate; and a second sound generating device disposed below the display panel, where the second generating sound generating device generates a sound by causing the display panel to vibrate. The first sound generating device includes: a first vibrator which vibrates in a first direction, which is a thickness direction of the display panel; and a second vibrator which vibrates in the first direction, and the second sound generating device includes: a third vibrator which vibrates in the first direction; and a fourth vibrator which vibrates in a second direction, which is perpendicular to the first direction.
