摘　　要：针对目前声频定向技术中出现的声音扭曲等问题,提出一种基于DSP的解决方案,并设计出了相应的硬件系统。将实际系统输出与仿真相比较,结果证明系统能实时快速地处理前期信号,从而更好地解决声音扭曲等问题,为声频定向系统的进一步商业化打好了基础。A solution based on DSP is presented to solve the problem of the distortion in the audio beam loudspeaker, and the hardware system for signal processing is designed. Compared with the idealized output from MATLAB, the real output of the hardware system is satisfactory for providing a real-time signal processing and lowering the distortion to the least. This design is expected to accelerate the commercialization of the audio beam loudspeaker.
