With reference to FIG. (1), the present invention relates to a sound synthesizer system for use in a vehicle having an internal combustion engine. The system 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 sound signals are produced thereby, the sound synthesizer) unit (12) varies the sound signals with changes in the speed of revolution signal and changes in the inclination signal. |
