如何提高录音制作和立体声电台接收重放的质量,我们进行了各种构思,首先着重解决音箱的重放质量是有必要的。因此我们设想,把传统的左右声道音箱重放系统试制成为“一体化立体声音箱”,以便提高立体声效果和改善音质。“一体化立体声音箱”的设计使我们得到一个启示:即低于300赫的低频分量由于没有强度差和相位差,故可以由两个LC滤波器分离出来,分别送到双音圈12英寸扬声器的两个音圈上,由这个扬声器重放出来。这种新频的双音圈12英寸布折环扬声器是1986年由广州国光电声器件厂与深圳大学共同研制的。利用
How to improve the recording production and stereo radio reception playback quality, we conducted a variety of ideas, first of all focus on the speaker playback quality is necessary. Therefore, we envisaged the trial production of a conventional left-right channel speaker playback system as an “integrated stereo speaker” to enhance the stereo effect and improve the sound quality. “All-in-one Stereo Speakers” is designed to give us a hint that low-frequency components below 300 Hz can be separated by two LC filters due to lack of intensity difference and phase difference and sent to two-voice coil 12-inch loudspeakers On the two voice coil, reproduced by this speaker. This new frequency dual-voice coil 12-inch cloth folded ring speaker was developed in 1986 by the Guangzhou Guoguang electro-acoustic device factory and Shenzhen University jointly developed. use
