Radio communication system for vehicle
First Claim
1. A radio communication system for a vehicle comprising:
- a radio communication apparatus mounted on helmets to be worn by a driver and a passenger of said vehicle and including at least a speaker, a microphone and a radio wave transmitter-receiver; and
a repeating apparatus mounted on said vehicle side for communicating with said radio wave transmitter-receiver;
said radio communication apparatus mounted on one of said helmets communicating with a second of said helmets through said repeating apparatus,wherein the repeating apparatus includes a mute function and attenuates or interrupts when a sound source having a higher priority order and another sound source having a lower priority order interfere with each other, a mixing section for combining signals received from two or more radio communication apparatuses, and a mix/mute section for mixing sound signals outputted from the mixing section, a portable telephone set, and a music reproduction apparatus, and providing an output transmission signal.

Abstract
A radio communication system for a vehicle which allows communication not only between a driver and a passenger of one vehicle but also with a driver or a passenger of another vehicle without increasing the scale of a radio communication apparatus to be mounted on a helmet. A radio wave signaled from a radio wave transmitter-receiver of a driver or a passenger of a vehicle is received by a repeating apparatus of the self-vehicle and amplified by and re-signaled from the repeating apparatus. The radio wave signaled from the repeating apparatus is received by a radio wave transmitter-receiver of a driver or a passenger of another vehicle and reproduced by a speaker. A radio wave signaled from the radio wave transmitter-receiver of the driver or a passenger of the vehicle is received by a repeating apparatus of the self-vehicle and amplified by and re-signaled from the repeating apparatus. The radio wave signaled from the repeating apparatus is received by the radio wave transmitter-receiver of a driver or a passenger of the vehicle and reproduced by a speaker.

15. A radio communication system for a vehicle comprising:
-
a radio communication apparatus mounted on each of helmets to be worn by a driver and a passenger of said vehicle and including at least a speaker, a microphone and a radio wave transmitter-receiver powered by a battery housed within a case of the transmitter-receiver, said radio wave transmitter-receiver including; a pair of operation buttons disposed one above another on one side of a rear face of the case, the operations buttons being disposed on either a right side or a left side of the case, and the battery being disposed in the right or the left side of the case opposite to the side where the operations buttons are disposed; and a repeating apparatus mounted on said vehicle side for wireless communication with said radio wave transmitter-receiver, said radio communication apparatus being mounted on one of said helmets communicating with a second of said helmets through said repeating apparatus, wherein said repeating apparatus repeats mutual communication between two radio communication apparatus mounted on each of the two helmets worn by the driver and the passenger of said vehicle and a radio communication apparatus mounted on a third helmet worn by a person other than the driver of the passenger of said vehicle, the repeating apparatus including; a mixing section for combining signals received from two or more radio communication apparatuses; and a mix/mute section for mixing sound signals outputted from the mixing section, a portable telephone set, and a music reproduction apparatus, and providing an output transmission signal. - View Dependent Claims (16, 17, 18)

19. A radio communication system for a vehicle comprising:
-
a radio communication apparatus mounted on each of helmets to be worn by a driver and a passenger of said vehicle and including at least a speaker, a microphone and a radio wave transmitter-receiver powered by a battery housed within a case of the radio wave transmitter-receiver; and a repeating apparatus mounted on said vehicle side for communicating with said radio wave transmitter-receiver, said radio communication apparatus mounted on one of said helmets communicating with a second of said helmets through said repeating apparatus, wherein said radio wave transmitter-receiver includes a mixing section for combining signals received from two or more radio communication apparatuses; a mix/mute section for mixing sound signals outputted from the mixing section, a portable telephone set, and a music reproduction apparatus, and providing an output transmission signal; a pair of operation buttons disposed one above another on one side of a rear face of the case; and a coil antenna accommodated along an upper inner side of the case, said radio wave transmitter-receiver being mounted in a predetermined posture at the center of the rear portion of each of said helmets.
