Provided is a sound generating device (20) for a vehicle, including: a plurality of pressure sensors (21 a to 21 d) for detecting air pressures of an air intake sound of an engine (12) and outputting the air pressures as sound pressure signals; a signal processing unit (24) for performing processing of changing the sound pressure signals in accordance with a driving condition of a vehicle (10); and loudspeakers (28a and 28b) for outputting the sound pressure signals as the air intake sound of the engine (12). Then, the plurality of pressure sensors (21a to 21d) are provided at an interval in a circumferential direction of an outer periphery of an air intake duct (15) at positions in a vicinity of an air flow meter (18) on an air cleaner (16) side with respect to a center of the air intake duct (15), the air intake duct (15) connecting the air cleaner (16) to a throttle body (17).
