Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vehicular intake sound transmission device easily installable in an engine room much in restriction on a space, and capable of transmitting an intake sound by a desirable frequency-sound pressure characteristic by resonating by a desired frequency. SOLUTION: A vibrator 14 blocking up the inside of a transmission pipe 11 and vibrating by intake pulsation, is arranged inside the transmission pipe 11 branching off from an intake pipe 4B and having the opening tip, and a tip side part more than the vibrator 14 in the transmission pipe 11, is formed as a cylindrical resonator 13. With this constitution, the resonator 13 is formed so that its passage cross-sectional area monotonously reduces toward the tip side from the base end side of a passage. COPYRIGHT: (C)2009,JPO&INPIT
