IPC: B62D25/20
Filed: 2006-02-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vehicular acoustic structure capable of obtaining a desired acoustic effect in a cabin while using an acoustic device or suppressing sound emission to surroundings.  <P>SOLUTION: In a vehicle 10, an exhaust pipe 16 and a vehicle body floor 30 are connected to each other via a plurality of sound bars 32. One end of each of the sound bars is fixed to the exhaust pipe, and the other end thereof is fixed to the vehicle body floor. When the exhaust pipe is oscillated by the drive of an engine, each sound bar is oscillated at each natural frequency. The vehicle body floor is oscillated by the oscillation of the exhaust pipe, and emits the sound of the natural frequency of each sound bar in a cabin. The sound emitted in the cabin is amplified by the cavity resonance. Thus, by setting the natural frequency of each sound bar to be the frequency of the desired sound, the sound of the desired frequency can be emitted in the cabin while suppressing the emission of the sound around the vehicle.  <P>COPYRIGHT: (C)2007,JPO&INPIT
