A vehicle sound generation apparatusis constituted by a first pressure sensor, a second pressure sensor, a signal processing sectionwhich performs processing of changing pressure signals output from the first pressure sensorand the second pressure sensorin accordance with the operation state of an automobile, and speakerswhich output, as an intake sound of an engine, a sound pressure signal processed by the signal processing section. The first pressure sensoris provided on an intake ductconnecting an air cleanerand a throttle bodyat a position between the air cleanerand the center of the intake duct, and the second pressure sensoris provided between the engineand the throttle body

Vehicle sound generation apparatus, and vehicle sound generation method

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