ABSTRACT:
A device for electroacoustic sound generation in a motor vehicle with a sound pressure sensor, a signal processing unit, which is connected with the sound pressure sensor and receives and processes signals therefrom, and a loudspeaker unit with at least one loudspeaker connected with the signal processing unit. The sound pressure sensor is arranged in the area of the intake tract or exhaust gas tract of the motor vehicle. To ensure a sound generation that is as variable as possible and nevertheless authentic, a synthesizer that is connected with, or integrated in, the signal processing unit is used so that synthetic sound components can be added to the signals generated from the sound pressure sensor.
