System for influencing exhaust noise and / or intake noise and / or engine noise

摘要

A system (7) for influencing exhaust noise and / or intake noise and / or engine noise of a vehicle has a controller (9) and at least one speaker (2), which speaker (2) for receiving control signals to the controller (9) is. In this case, the at least one loudspeaker (2) is designed as a function of a control signal received by the control (9) for generating a sound in an associated sound generator (3). The controller (9) comprises at least one microprocessor (91, 91 '), at least one digital-to-analog converter (92), at least one amplifier (93) and an up-converter (97). The at least one microprocessor (91, 91 ') is designed to generate a digital control signal which is suitable for extinguishing sound in the interior of an exhaust system (4) and / or intake system (12) of the vehicle at least partially and preferably completely in magnitude and phase and / or to generate noise and in particular engine noise inside an engine compartment. The at least one digital / analog converter (92) is connected to the at least one ...
