Method for operating stereo-loudspeaker system, involves delaying central loudspeaker controlling signal against signals for controlling lateral loudspeakers for quotients of specific distance and sound speed

摘要

The method involves delaying a central loudspeaker controlling signal against the signals for controlling the lateral loudspeakers (12,14) for the quotients of a specific distance (x) and sound speed. The acoustic center of the central loudspeaker (10) has the specific distance from the fictitious connecting line between the acoustic centers of the lateral loudspeakers. The three speakers are not acoustically coupled, and have consistent acoustic properties.
