置。The rotation speed of the power system such as the drive shaft or wheels is detected as a pulse, and the pulse is converted into a pulse train change having a period corresponding to the rotation speed through a pulse shaper and a monostable multivibrator, and then through an integrating circuit and a DC amplifier. Convert it into a DC voltage, convert the frequency using a voltage control variable frequency oscillator with a single pulse generation circuit, and convert the converted frequency from idle sound to rotation speed through a voltage control gain amplifier controlled by the DC voltage. A sound oscillation device configured to oscillate engine sound having proportional sound quality and volume.
