摘要:
A sound generator system (1, 70), for a vehicle with internal combustion engine (15) and/or electric motor, has an electroacoustical transducer (11) and a control unit (24, 74). Transducer (11) produces an acoustical signal based on an electrical input signal and is connected to an acoustic line. The control unit (24, 74) creates a primary audio signal with frequencies from a given frequency range, to selectively amplify selected segments (“V”) of the primary audio signal so that the audio signal (41) amplified in the selected segments has a section in which all audio signal values correspond to a maximum amplitude value that is specified for the segment, and the audio signal (41) amplified in the selected segments is continuous at transitions from the at least one section to neighboring sections, and wherein the audio signal (41) generated by the control unit (24) forms the basis of the electrical input signal.
