A display apparatus is capable of outputting a stereo sound. The display apparatus includes a display panel configured to display an image; a sound generating device on a rear surface of the display panel; a rear cover on the rear surface of the display panel and configured to support the sound generating device; a partition member between the rear surface of the display panel and the rear cover and configured to divide the display panel into first, second, third, fourth and fifth areas; and first, second, third, fourth, and fifth sound generating devices attached to the rear surface of the display panel and configured to vibrate the display panel. The first, second, third, fourth and fifth sound generating devices are in the first, second, third, fourth and fifth areas, respectively.

A display device includes a display panel which displays an image, a cover window which is disposed on a first surface of the display panel, and a first sound generator which is disposed on a second surface opposite the first surface of the display panel and outputs sound by vibrating the display panel. The cover window includes a first lattice pattern area including lattice patterns surrounding the first sound generator in a plan view.

The present disclosure provides an acoustic output apparatus including one or more status sensors, at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, at least two first sound guiding holes, and at least two second sound guiding holes. The status sensors may detect status information of a user. The low-frequency acoustic driver may generate at least one first sound, a frequency of which is within a first frequency range. The high-frequency acoustic driver may generate at least one second sound, a frequency of which is within a second frequency range including at least one frequency exceeding the first frequency range. The first and second sound guiding holes may output the first and second spatial sound, respectively. The first and second sound may be generated based on the status information, and may simulate a target sound coming from at least one virtual direction with respect to the user.

A display apparatus is disclosed, which includes a display panel including a first area and a second area, a first rear cover disposed below a rear surface of the display panel, a first sound generating module arranged in the first area to adjoining the display panel, and a second sound generating module arranged in the second area to be spaced apart from the display panel, wherein the first rear cover includes a first rear cover port hole formed to overlap the second sound generating module, the second sound generating module includes an enclosure disposed below a rear surface of the first rear cover and coupled with the first rear cover, and a second sound generating unit mounted in the enclosure, and the enclosure includes an enclosure port hole overlapped with the first rear cover port hole.

A virtual reality (VR), augmented reality (AR) and/or mixed reality (MR) system in a physical environment with a plurality of loudspeakers includes a user-worn head mounted display (HMD), a VR/AR/MR processor, and a VR/AR/MR user tracking processor. The HMD includes a microphone and a user tracking device configured to track a user orientation and position. The VR/AR/MR processor delivers a digital video signal to the head-mounted display, and a digital control signal and a digital audio signal to a receiver/preamplifier. The VR/AR/MR user tracking processor receives user tracking data from the HMD user tracking device and provides a digital user tracking data signal to the receiver preamplifier. the receiver/preamplifier receives the digital user tracking data signal, the digital control signal, the digitized microphone signal, and the digital audio signal, and provides a processed audio signal to the amplifier. An amplifier receives the processed audio signal and provides amplified audio signals.
