摘要: First auxiliary speakers are mounted in the vehicle-passenger space with respect to main speakers providing for acoustic reproduction in the vehicle-passenger space. The first auxiliary speakers output sound in the same frequency band as that of sound outputted from the main speakers. Acoustic outputs of the first auxiliary speakers are set to make a sound pressure of the sound reaching a listener sit in the vehicle-passenger space from the first auxiliary speakers nearly equal to a sound pressure of the sound reaching the listener from the main speakers.
