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.

A sound proving method of a display device, comprising:
- shifting a phase of a fundamental tone of a first sound in a first sound mode to generate a fundamental tone of a second sound;
- shifting a phase of at least one harmonic tone of the first sound in the first sound mode to generate at least one harmonic tone of the second sound;
- outputting first sound data comprising information about the fundamental tone of the first sound and the at least one harmonic tone of the first sound in the first sound mode, and outputting second sound data comprising information about the fundamental tone of the second sound and the at least one harmonic tone of the second sound in the first sound mode;
- generating first sound signals according to the first sound data and outputting the first sound signals to a first sound generator;
- and
- generating second sound signals according to the second sound data and outputting the second sound signals to a second sound generator.
