Sound production device, sound-production-device equipped vehicle, and sound production method
Abstract:
A sound production device includes memories, processors, a rotation speed correlation value acquisition device configured to acquire a rotation speed correlation value of a rotating body, and a speaker. A noise order sound has a characteristic in which a sound pressure of the noise order sound reaches a maximum sound pressure in a first range of the rotation speed correlation value, and the sound pressure becomes smaller than the maximum sound pressure in second ranges adjacent to both sides the first range. When the rotation speed correlation value falls within the first range, the processors do not output a dummy noise. When the rotation speed correlation value falls within either of the second ranges, the processors output the dummy noise.
