The Phased-Array Speaker System
Heng Wang · Journal of Guangzhou University · 2012
The general speaker system,which is based on the mechanical vibrations and acoustic,acquires a good performance,and the current line-array speaker gives full play to the physics and acoustic at present,Phased-Array Speaker System combines the electronic technology,digital technology,computer technology and electroacoustic technology and use the DSP technology creatively,develops applicable algorithm for the phase control and sound processing at each frequency band,in order to control the radiation angle,directivity,sound effect of the main radiation lobe.The experts identified the system as reach the international advanced level.The thesis discusses the design principle,structure,features and the engineering application of the Phased Array Speaker System which is a research project combined provincial ministry,education,production.
