DRIVING-LINKED SOUND GENERATION DEVICE

A running-linked sound generation unit includes an order sound data generation unit, a random sound data generation unit, and a synthesis unit. The order sound data generation unit generates order sound data by changing the tone of basic order sound data according to a motor rotation speed of a vehicle. The random sound data generation unit generates random sound data by changing the volume of basic random sound data according to a motor rotation speed and an accelerator command value of a vehicle, without changing the tone of the basic random sound data. The synthesis unit generates synthetic sound data by combining synthesized order sound data and random sound data.
