Abstract
A resonatoris provided including a resonating bodywhich is vibrated by intake air pulsation in an intake system, a volume chamberconnected through the resonating bodyto the intake system, and a neck sectionthrough which an interior spaceof the volume chamberis communicated with outside. The interior spaceof the volume chamberand interior of the intake systemare partitioned by the resonating body. The resonator is so set that a sound pressure in a certain frequency range is released from the neck sectionto the outside under vibration of the resonating body. With this, the sound pressure characteristics of air intake sound can follow a rise in engine speed.
