ABSTRACT:
A resonator13is provided including a resonating body13which is vibrated by intake air pulsation in an intake system5, a volume chamber14connected through the resonating body13to the intake system5, and a neck section16through which an interior space15of the volume chamber14is communicated with outside. The interior space15of the volume chamber14and interior of the intake system5are partitioned by the resonating body13. The resonator is so set that a sound pressure in a certain frequency range is released from the neck section16to the outside under vibration of the resonating body13. With this, the sound pressure characteristics of air intake sound can follow a rise in engine speed.
