PORTABLE VIEWER SYSTEM AND HEADPHONE DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a portable viewer system which makes it possible to use at least a headphone device and a viewer device without connecting the both by a wire. SOLUTION: A main body device 3 supplies an audio signal and a video signal to the viewer device 1 through an AV cable 9. The viewer device 1 displays the supplied video signal on a liquid crystal monitor 8 and transmits infrared rays modulated with the audio signal from an infrared-ray emission part 7 to an infrared-ray reception part 4 of the headphone device 2. The headphone device 2 demodulates the received infrared rays into the audio signal and outputs it from its internal speaker. |
