Abstract:
Sound effects are generated from a speaker inside a vehicle compartment repeatedly between a lower limit frequency and an upper limit frequency in accordance with an increase in the vehicle velocity. Consequently, the frequency is increased with respect to an increase in the vehicle velocity, in a manner so that audible sound effects, that is, sound effects at a so-called infinite scale, are generated.

Claim (Index 1):
An active sound effect generating device installed in a vehicle equipped with an electric motor as a drive source for the vehicle, comprising:\n a vehicle velocity detecting device configured to detect a vehicle velocity; and a vehicle velocity corresponding frequency setting unit configured to set a vehicle velocity corresponding frequency of a sound effect made up from frequencies having a plurality of ordered components so as to be generated from a speaker in accordance with a detected vehicle velocity; wherein the vehicle velocity corresponding frequency setting unit is configured to set the vehicle velocity corresponding frequency between a lower limit frequency and an upper limit frequency, and exponentially increase the frequencies having the plurality of ordered components in accordance with an increase in the vehicle velocity, respectively, from the lower limit frequency to the upper limit frequency, together with setting a frequency ratio of the plurality of ordered components so as to have a constant multiple relationship, and performing a control in a manner so that the sound effect is generated repeatedly between the lower limit frequency and the upper limit frequency in accordance with an increase in the vehicle velocity.
