This paper analyzes the sound field of virtual sound reproduction, and proves that, to some extent, virtual system with three loudspeakers can overcome the defect of the system with two loudspea_ kers, its listening area is enlarged and the stability of sound image is improved, and that the method of virtual reproduction with three loudspeakers can be used to recreate side image in 5.1 ch surround sound and applied to domestic use as well as the simulation of room sound field.

对虚拟声系统的重发声场进行分析与实验 ,证明了采用三扬声器虚拟声重发系统可在一定程度上克服两扬声器系统的缺陷 ,其听音区域得到扩大 ,声像稳定性得到提高 .并且指出 ,三扬声器虚拟声重发的方法可用于 5.1通路环绕声的侧向声像重发、家庭影院的环绕声重发和室内声场可听化模拟 .

The sound fields created by a sound reproduction systems with three loudspeakers at listener's position are analyzed. It was proved that the listener's area (sweet spot ) created by the system was large. This system can also reproduce higher frequency sound signal. At the same time the stability of sound-image is also better. The optimum loudspeaker arrangement will be decided according to the frequency of reproduced sound signal. This system has great prospects for the room acoustics simulation,...

This system has great prospects for the room acoustics simulation, multimedia computer system, and family cinema.

本文对一种三扬声器重发系统中倾听者所在区域的声场进行了分析。结果表明 :采用该三扬声器系统重发声信号 ,其听音区域 (“甜点”范围 )大 ,可重发较高频率的声信号 ,系统声像稳定性较好。重发时 ,可根据重发信号频率来确定使系统达到最佳效果的扬声器布置方案。该系统将在室内声场模拟、多媒体计算机、家庭影院等方面具有广阔的应用前景。

An improved three loudspeakers virtual reproduction system for 5.1 channel surround sound is presented. Firstly, it is pointed out that there are some defects in the current virtual reproduction system, including narrow listening area, instability in sound image, etc. Then, it is proved by theory and experiment that by using a pair of full band loudspeakers placed in front ±30° and a tweeter placed in front 0°, the sound image stability of the virtual reproduction system for 5.1 channel surround...

An improved three loudspeakers virtual reproduction system for 5.1 channel surround sound is presented. Firstly, it is pointed out that there are some defects in the current virtual reproduction system, including narrow listening area, instability in sound image, etc. Then, it is proved by theory and experiment that by using a pair of full band loudspeakers placed in front ±30° and a tweeter placed in front 0°, the sound image stability of the virtual reproduction system for 5.1 channel surround sound can be improved. This arrangement of loudspeakers is feasible and the signal processing procedure is simple. Therefore the improved system is suitable to be used in TV sets and multimedia computers.

提出一种改进的5.1通路环绕声的三扬声器虚拟重发系统。本文首先指出,现有的两扬声器虚拟重发存在听音区域窄、声像稳定性差等缺陷。通过理论分析和心理声实验证明,采用一对布置在前方±30°的全频带扬声器和一个前方0°的高频中置扬声器组成5.1通路环绕声虚拟重发系统,不但可提高重发声像的稳定性,且扬声器布置实际可行,信号处理相对简单。因此所提出的虚拟系统及其扬声器布置是适合于电视和多媒体计算机的应用。
