Abstract

See full text

There is provided a sound generating device for vehicles that is capable of improving the sensing of acceleration feeling. The sound generating device for vehicles includes an input unit that receives an input of a speed of a vehicle; and a generation unit that generates a sound including a plurality of frequency components when the speed of the vehicle is a first speed. When the speed of the vehicle changes from the first speed to a second speed (higher than the first speed), the generation unit shifts the frequency components included in the sound to a higher frequency side and reduces the sound at a higher frequency band in the shifted frequency components. The generation unit preferably performs pitch shift processing and low pass filter processing (and more preferably performs moving average processing) on the sound.
