文中应用了重发声场中声像位置与各扬声器位置及其发出声强之间的关系,普遍地探讨了矩阵型四通路立体声系统;证明了如果传输(或记录)通路只用两个时是不可能获得一个无声像位置畸变的全景重发声场的,因此,就肯定了一切4-2-4型的矩阵立体声系统都不是完美的全景(立体)声系统。文中也证明了当传输(或记录)通路增至三个时,就完全有可能取得一组信号及其相应的矩阵译码电路,使馈给一定排列的扬声器组的信号产生一个无声像位置畸变的全景(立体)声场。举出了这样一组信号及其相应的译码矩阵寻求方法的例证。但是,这些都不是唯一的,而有许多类似的系统存在。
In this paper, the relationship between the position of the sound image in the re-emitted sound field and the position of each loudspeaker and the sound intensity of the loudspeaker is discussed. The matrix type four-channel stereo system is generally discussed. It is proved that if the transmission (or recording) It is impossible to obtain a panoramic soundfield with no distortion like position distortion, so that it is certain that all 4-2-4 matrix stereo systems are not perfect panoramic (stereo) sound systems. It has also been demonstrated that when the number of transmission (or recording) paths is increased to three, it is entirely possible to obtain a set of signals and their corresponding matrix decoding circuitry to produce a silent image position distortion for the signals fed to a given array of loudspeaker groups Panoramic (stereo) sound field. An illustration of such a set of signals and their corresponding search matrix seeking methods is given. However, none of these are unique, and many similar systems exist.
