PURPOSE:To effectively absorb the voice of a driver by using a telephone for vehicle by installing a microphone onto the webbing of a seat belt so that the seat belt is positioned in the vicinity of the mouth of the driver, when the driver is applied with the seat belt. CONSTITUTION:The microphone 2 of an on-vehicle hand-free phone is installed onto a flexible basic plate 2a installed onto a frame part 1a made of the same material to that of the webbing 1 of a seat belt, and said frame body 1a is installed into the hollow part 1b of the webbing 1 through seaming. In this case, the installation position of the microphone 2 is set at the position where the microphone 2 is set in the vicinity of the mouth of a driver D when the driver D is applied with the seat belt. The microphone 2 is connected with a hand-free control circuit (not show in the figure) through a cable 2b. Therefore, the voice of the driver D can be effectively absorbed, and generation of howling can be prevented. |
