A sound synthesizer system, for use in a vehicle having an internal combustion engine, comprises: a sound synthesizer unit 12 operable to produce sound signals by generating and combining signals of different frequencies; a speed sensor 10 for providing a speed of revolution signal indicative of speed of revolution of the internal combustion engine of the vehicle; and an inclinometer 11 attachable to a throttle control of the internal combustion engine which provides an inclination signal indicative of inclination of the throttle control. The sound synthesizer unit 12 receives the speed of revolution signal from the speed sensor 10 and the inclination signal from the inclinometer 11 and uses both signals to determine what 20 sound signals are produced. It then varies the sound signals with changes in the speed of revolution and inclination signals. The system may be portable and able to connect to a loudspeaker entertainment system of the vehicle. |
