  • the electromechanical Converter is usually a speaker, wherein the actuator is the speaker diaphragm is and the drive is effected by an electric coil, in which a bobbin introduced is.
  • the cooling of the components mentioned allows the choice of a smaller drive for the speaker, because of overheating and consequent failure of the converter can be counteracted by a continuous load. Thereby can be saved advantageously not only installation space and weight. Another positive effect is the ability to use less expensive speakers.
  • the drive accommodated in the line system is that this with a clean side of the line section formed by the filter communicated.
  • the drive can be protected in this way against contamination when installed in the ducting system in such a way that it is directly connected to the subsidized gas communicates. This is especially the case when the drive is direct exposed to the gas stream.
  • the advantage with the pure-side arrangement is the omission an encapsulation that protects the sensitive drive from contamination. Consequently can also be saved by this measure space, component part weight and cost become.
  • both sides of the membrane are used to influence the intake noise, may be an acoustic vote according to another embodiment of the inventive concept done by additional channels and / or volumes. It is targeted the Superposition of the generated by both sides of the membrane air vibrations used.

These driving conditions can be stored together with other maps in the controller and thus form the parameters for the desired sound to be achieved. Through the store can continue to change the noise characteristics of the engine or the intake tract to be compensated by pollution or aging is effected.

This is superimposed on the intake noise 21 of the internal combustion engine, which propagates through the intake tract 11. This results in an actual noise 22, which z. B. can be measured by the sensor 16 at the intake manifold 15. This results in the Istge syndromeschsignal I.
