摘要： An intake air sound generation device 40 for an internal combustion engine 2, comprises an introduction tube 41 which is connected to an intake passage 30 of the internal combustion engine 2 to introduce an intake pulse of an intake system, a vibrating body 50 which has a vibration surface 52 that is vibrated by the intake pulse and an accordion portion 53 that promotes vibration of the vibration surface 52, and is provided to cover one end of the introduction tube 41, and a resonance tube 42 which is connected to the introduction tube 41 via the vibrating body 50 and increases a sound pressure in a predetermined frequency band of an intake air sound generated by the vibration of the vibration surface 52. Thus, the sound pressure of the intake air sound at the predetermined frequency can be increased, and the durability of the vibrating body 50 can be improved.
