Title:
SURROUND LOUDSPEAKER SYSTEM
Document Type and Number:
Japanese Patent JP3885332
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To select an audio reproduction system such as a direct system, a dipole system and a bi-pole system depending on a characteristics and a kind of a sound source, preference of a listener, a configuration of a room for audio reproduction and the layout of loudspeakers or the like.
SOLUTION: First to third acoustic output level operation means for 1st to 3rd loudspeakers is respectively interlocked in 1st and 2nd operation areas. In the 1st operation area, the acoustic output level of a 1st speaker SP1 is adjusted between a maximum level and zero level, the 2nd speaker SP2 connects with the 1st speaker SP1 in inverted phase, and the acoustic output level is adjusted between a maximum level and zero level. The 3rd speaker SP3 connects in phase with the 1st speaker SP1 and the acoustic output level is adjusted between a maximum level and zero level. In the 2nd operation area, the acoustic output level of the 1st speaker SP1 is adjusted between a maximum level and zero level, the 2nd speaker SP2 connects in phase with the 1st speaker SP1, the acoustic output level is adjusted between a maximum level and zero level, and the 3rd speaker SP3 connects in phase with the 1st speaker SP1, and the acoustic output level is adjusted between a maximum level and zero level.
