DEVICE FOR SIMULATING SOUNDS OF A VEHICLE ENGINE, REPRODUCED BY AN EXHAUST GAS SYSTEM Russian patent published in 2020 - IPC G10K15/02 

FIELD: transport machine building.

SUBSTANCE: invention relates to technical means used in exhaust systems of a vehicle. Disclosed is a device for simulating sounds of a vehicle engine, reproduced by an exhaust gas system, which consists of electronic unit with pre-recorded or synthesized sound patterns installed in it. Performing installation using mobile application, having function of updating pre-recorded or synthesized sound templates loaded into it, connected to CAN and vehicle ACC circuits. Device comprises an acoustic system comprising at least one speaker attached to the inner part of the upper cover of the housing of the speaker system, intended for reproduction of pre-recorded or synthesized sound templates selected from the whole set and changed dependence on information on CAN bus circuits. At that, adjustment of sound template volume, and/or start sound, and/or number of projections, and/or idle stroke, and/or working stroke tone is performed by means of mobile application and/or using buttons installed in car cabin.

EFFECT: technical result consists in improvement of accuracy to generate and simulate specific sounds of vehicle engine, reproduced by system of exhaust gases.
