ABSTRACT:
A sound production controller can include a horn device that performs a vibrating operation at a predetermined resonance frequency in response to a predetermined operation to produce a warning sound, an input section which receives a sound production command signal outputted in response to execution of a function that requires sound production in the vehicle other than the predetermined operation, and a sound production controller which, if the input section receives the sound production command, provides a high-frequency signal having a frequency higher than the predetermined resonance frequency to the horn device to cause the horn device to produce a sound.
