问:《象牙一号》如此高大的造型主要是为了美观还是为了音质?答:主要是为了音质,因为《象牙一号》采用1/4波长加载(QWL)声学原理设计,所谓1/4波长加载(QWL)型音箱,是指一长度等于扬声器谐振频率1/4波长的楔形锥管,在其中心部位安装喇叭。谐振时,愈趋向锥端声阻愈大,作为负载反作用于喇叭,抑制其振幅,达到降低失真的目的,多余的能量从底部的音孔释出,由于《象牙一号》的谐振频率是47Hz,而47Hz的1/4波长等于1.8米,这就是《象牙一
Q: “Ivory One” such a tall shape is mainly for the aesthetic or for the quality? A: mainly for the sound quality, because the “Ivory One” using 1/4 wavelength loading (QWL) acoustic principle design, the so-called 1/4 wavelength Loaded (QWL) speakers are tapered wedges with a length equal to ¼ wavelength of the speaker’s resonant frequency, with a horn installed in the center. Resonance, the more toward the cone end of the acoustic impedance greater, as the reaction load on the speaker, inhibit its amplitude, to reduce the distortion of purpose, the extra energy from the bottom of the sound hole release, because the “Ivory” resonance frequency is 47Hz , And 1/4 wavelength of 47Hz is equal to 1.8 meters, this is "Ivory one
