扬声器已问世多年了,如何改进播放音乐的质量、效果,使听众坐在音响设备前,宛如置身于音乐厅,能收到最佳音响效果,这一直是科学工作者孜孜以求的目标。老式扬声器的最佳立体声效果充其量也只能在一个固定点上才能享受到,因为两个扬声器发出的声音是在三角形的一点上复合成立体声的。dbx公司新近推出的声场组合器在这方面前进了一大步,它采用了最新式的相控阵技术,内装14个分离式扬声器,包括低频低音、中音及高频高音扬声器,一种尖端的交叉系统将其组合起来,对每个扬声器四周的音量、音频及相位信号加以控制,使其可向任何方位发出 Speakers have been around for many years. How to improve the quality and effect of playing music so that the listeners sit in front of the audio equipment is like being in a concert hall and receiving the best sound, which has always been the goal pursued by scientists. The best stereo effect of the old-fashioned loudspeaker can only be enjoyed at a fixed point, at best, since the sound of the two loudspeakers is combined into a stereo at one point on the triangle. dbx recently introduced a sound field combiner in this regard a big step forward, it uses the latest phased array technology, built-in 14 separate speakers, including bass, midrange and high-frequency tweeter, a sophisticated The crossover system combines them to control the volume, audio and phase signals around each speaker so that it can be sent in any direction
