Speaker system with resonance frequency approximately identical to the peak frequency of the sound pressure
摘要：
A speaker system includes: a speaker cabinet; a speaker unit installed in a wall surface of said speaker cabinet; and an acoustic tube having ends, one of which is open and the other of which is closed, in which said acoustic tube is provided in said speaker cabinet such that a side wall surface of said acoustic tube crosses a direction in which standing waves propagates, the waves occurring inside said speaker cabinet.
摘要（中）：

扬声器系统包括：扬声器箱; 扬声器单元，安装在所述扬声器柜的壁面上; 以及具有端部的声管，其中一个是开放的，另一个是封闭的，其中所述声管设置在所述扬声器箱中，使得所述声管的侧壁表面与驻波传播的方向相交， 所述扬声器箱内发生的波浪。
