WIPO Patent Application WO/2021/027565
Kind Code:
A1
Abstract:
Disclosed is a flat-panel display device (10), comprising a display screen (100) and a display back plate (200) arranged in a stacked manner, wherein a first telescopic assembly (500) can drive a chassis (300), a first loudspeaker (710), a second loudspeaker (720) and a second telescopic assembly (600) to move back and forth in a first direction relative to the display back plate (200); and the second telescopic assembly (600) can drive the second loudspeaker (720) to move back and forth in a second direction relative to the display back plate (200) and the first loudspeaker (710). The first loudspeaker (710) and the second loudspeaker (720) cooperate with each other to provide a good sound production effect and a concise appearance; and the second loudspeaker (720) is firstly retracted in the second direction, and then, the first loudspeaker (710) and the second loudspeaker (720) are simultaneously retracted in the first direction, so that the first loudspeaker (710) and the second loudspeaker (720) are both hidden in the display back plate (200), so there is no effect on the appearance. A plurality of motion modules (400) are integrated on the same chassis (300), thereby improving the space utilization; and the first telescopic assembly (500) and the second telescopic assembly (600) are integrated on the same fixing support (310), also improving the space utilization, and making the overall structure more compact and concise.
