FIELD: transport.SUBSTANCE: invention relates to automotive sound radiators. Proposed sound radiator is designed to radiate sound beyond the limits of carrier at forward and reverse motion in response to gear shifting at said forward and reverse motion. Warning sound control device comprises the section of time synchronisation of sounds warning about forward motion to set the time of forward motion warning signal switching on in response to gear shifting for forward motion and to execute extra operation of carrier motion preparation. Section of time synchronisation of sounds warning about reverse motion to set the time of reverse motion warning signal switching on in response to gear shifting for reverse motion.EFFECT: sound generation depending on carrier motion direction.4 cl, 6 dwg |
