The passenger of the back seat receives and listens to a voice signal by wearing a head-phone 14. The first 1R transmission part 12 and the second 1R transmission part 13 light-modules the same voice information, and emits it to a space. For example, an LED for emitting an infrared ray is used as a converting element. The first 1R transmission part 12 transmits the signal from the front part to the back part, and the second 1R transmission part 13 transmits it from the back part to the front part. Especially, the signal is transmitted by the second 1R transmission part 13 to the front part including the driver's seat of the vehicle 11 so that it is possible to eliminate any dead zone in the vehicle.
