摘要：PROBLEM TO BE SOLVED: To provide a high-performance loudspeaker system which has a smooth sound pressure frequency characteristic and is excellent in low-pitched sound reproduction. SOLUTION: An acoustic tube 5 having an opening 8 in its one end is coupled to the back of a loudspeaker 6, an space wherein sonic waves can pass is secured in the middle of the path of the acoustic tube 5, and a partition 7 is disposed non-parallel to and between confronted parallel sidewalls of the acoustic tube 5 to eliminate a sound pressure peak caused by standing waves generated between the parallel confronted surfaces of the sidewalls, thereby the high-performance loudspeaker system is provided which has the smooth sound pressure frequency characteristic and is excellent in low-pitched sound reproduction.
