| Abstract: | 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. |
