| description | A sound inspection method of a display device and a sound inspection device including preparing a display device including a display panel and a sound generator disposed on a first surface of the display panel, placing a vibration sensor on a second surface opposite to the first surface of the display panel, vibrating the sound generator at a first reference frequency, vibrating the display panel, and then sensing a vibration of the vibration sensor that vibrates along with a vibration of the display panel; and determining whether a frequency of the vibration of the vibration sensor is included in a first threshold frequency region. |
