In the case where the surround signal is reproduced by -6, surround reproduction can be realized without installing a separate surround speaker. In addition, as described above, since the ceiling and wall reflections are used, the loss of localization due to the room conditions and the movement of the listening position of the listener U is small, which can be realized at a lower cost than the conventional speaker device. it can.
Further, the media playback unit 52 of the present embodiment plays the front signal including the center signal in the main speakers 55a and 55b as shown in FIG. ˜6, the L surround signal and the R surround signal are reproduced by the two speakers 4 and 6 positioned substantially orthogonal to the direction of the listener U, and substantially parallel to the direction of the listener U. Surround signals are reproduced by the two speakers 3 and 5 positioned in the direction. Even in this case, the same effect as described above can be obtained.

Further, when the center signal is not reproduced as the main speaker or when the center speaker is not set separately, the media reproducing unit 52 is substantially orthogonal to the direction of the listener U as shown in FIG. The two surround speakers 4 and 6 reproduce the left surround signal and the right surround signal, and the speaker 3 located in front of the two speakers located in a direction substantially parallel to the direction of the listener. Play the center signal. In this way, it is possible to realize surround playback with a center channel (channel) without installing a center speaker in front of the listener U.
In the case of performing surround playback as described above, the media playback unit 52 performs predetermined processing on the audio signal based on the head-related transfer function stored in the memory 58, for example, frequency characteristic change or delay processing. Thus, more accurate surround reproduction can be realized for the listener U at a predetermined position. In this case, as the head-related transfer information based on the head-related transfer function, a plurality of head-related transfer functions with different conditions such as the room size and the speaker device 1 are stored in the memory 58 in advance.
