Abstract: The electronic device includes a device housing, an emitter, a receiver, and a reflection structure. The emitter is separated from the device housing and emits an optical signal. The receiver is disposed on the device housing for receiving the optical signal. The reflection structure is formed on the device housing and neighboring to the receiver. When the emitter is disposed in front of the device housing, the optical signal transmitted from the emitter directly reaches the reflection structure and is reflected by the reflection structure, and then the optical signal travels toward the receiver.

Abstract: A display device includes an enclosure, a pair of speakers, and a sound reflector accommodated in the enclosure. The sound reflector defines two chambers for receiving the sounds generated from the pair of speakers respectively and outputting the sounds out of the display device independently.

Abstract: A flat panel display device includes a housing, a display panel, a main frame, a power supply module, and a circuit board assembly. The housing is for receiving the display panel, the main frame, the power supply module, and the circuit board assembly. The main frame is fixed on the housing and is integrated with the housing. The display panel is secured on the main frame. The power supply module is secured on the main frame and is electrically connected to the display panel. The circuit board assembly is secured on the main frame and is electrically connected to the display panel and the power supply module.

Abstract: A display device includes a cabinet, a display screen, and a speaker. The display screen is accommodated in the cabinet. The display screen includes a display surface. The display surface is used for displaying video images. The speaker is accommodated in the cabinet, and used for generating sounds. The generated sounds disperse along a first direction substantially perpendicular to the display surface of the display screen.
