由于单只扬声器只能在一段频率内发声,要达到从高音到低频的全频率发声,就必须由两只以上扬声器进行组合。传统音箱的高、中低音分别由三只扬声器担任,这样的音箱发出的声音在高度方向有位置差,在前后方向有距离差,声音到达人耳产生因时差而出现的失真,由此影响了声音还原的清晰度和声像定位的准确性。英国人在潜心研究后提出了同轴发声理论,产生了天朗和KEF这样的世界知名公司。 Since a single speaker can only sound within a certain frequency, to achieve full frequency sound from high to low frequency, it must be composed of two or more speakers. The traditional loudspeaker’s bass and mid-bass speakers are each operated by three loudspeakers. The sound emitted by such a loudspeaker is poorly positioned in the height direction and has a poor distance in the front-to-back direction. Distortion resulting from the time difference between the arrival of the sound and the ears affects The sharpness of sound reduction and the accuracy of sound image localization. The British put forward co-articulation theory after painstaking research, resulting in world-renowned companies such as Tienlang and KEF.
