ACOUSTIC DEVICE FOR VEHICLE, AND ACOUSTIC METHOD FOR VEHICLE

摘要

An acoustic device (20) for a vehicle is configured from a plurality of pressure sensors (21a to 21d) for detecting air pressure created by the suction noise of an engine (12) and for outputting said air pressure as an acoustic pressure signal, a signal processing unit (24) for changing the acoustic pressure signal in accordance with the operational state of an automobile (10), and speakers (28a, 28b) for outputting the acoustic pressure signal as the suction noise of the engine (12). The pressure sensors (21a to 21d) are disposed in the circumferential direction at an equal distance from one another on a section on the outer circumference of a suction duct (15) for connecting the air cleaner (16) with a throttle body (17), the aforementioned section being in the vicinity of an air flow meter (18) closer to the air cleaner (16) than to the center of the suction duct (15).
