Abstract
A display device having a speaker module includes a display, an ultrasonic speaker and an adjustment module. The speaker module includes at least one first speaker module and at least one second speaker module. The first speaker module is disposed at the display and adapted to emit a first ultrasonic wave. The second speaker module is disposed at the display and adapted to emit a second ultrasonic wave. The first ultrasonic wave and the second ultrasonic wave are intersected to form an audible region. The adjustment module is adapted to control the first speaker module and the second speaker module to rotate relative to the display, so as to drive the audible region to target a user.
