Abstract:
To provide a sound generation device, a sound generation program and a control device capable of achieving high sound pressure while suppressing a failure.SOLUTION: A sound generation device comprises a sound generation unit which generates a sound based upon a PWM signal, a PWM signal generation unit which generates the PWM signal, and an indication unit which sends an indication to change the frequency of the PWM signal to the PWM signal generation unit. The PWM signal generation unit is configured to provide, when the indication unit sends the indication to change the frequency, a standby time before changing the frequency from a first frequency to a second frequency, and then fix a signal of the standby time at a level Low.SELECTED DRAWING: Figure 8
