Abstract (en)
[origin: EP1152132A1] The system has a pipe section (25) with an induction opening and an electromagnetic transducer (14) producing noise to influence the gas flow in the pipe section, especially to correct engine induction noise. The transducer has an actuator for noise generation, especially a membrane, with a drive (27), especially an electric coil (32). The drive is mounted in the pipe system so as to be exposed to the gas flow transported in the pipe system. Independent claims are also included for the following: the use of a pipe system in the induction system of an internal combustion engine.
