摘要

Tree-structure NSDEM method has been proposed as a method to suppress and reduce the circuit size due to the number of sub-speaker of a digitally direct driven speaker. In this study, we applied this tree structure NSDEM to a directivity speaker system using digitally direct drive method, and simulation and actual measurement are carried out and the results are presented.
