Abstract:
The above sound reproduction device is applied to an acoustic space such as a passenger compartment, and controls the levels of the reproduced sounds at two evaluation points set at the seats in the passenger compartment, for example. Specifically, the sound reproduction device controls the phase of the sound signal inputted from external and supplies the sound signals to the pair of speakers. The phase control is performed for each of the plurality of listening positions such that a sum of reproduced sound levels at the two evaluation points becomes larger than the sum obtained in a case where the sound signal is reproduced only one of the pair of speakers.
