PERFORATED PHASE ALIGNMENT TWEETER SCREEN

摘要

A protective screen for a diaphragm of a loudspeaker comprises a first side and a second side. The screen comprises a perforated region and an imperforated region. The perforated region comprises a first perforation having a first size and a second perforation having a second size, each perforation passing through the first side and the second side of the screen, and each perforation allowing sound waves radiated from a first portion of the diaphragm to pass through the screen. The imperforated region suppresses sound waves radiated from a second portion of the diaphragm. The first perforation is more adjacent to the imperforated region than the second perforation, and wherein the second size of the second perforation is bigger than the first size of the first perforation.
