View page
US Patent:
45124345, Apr 23, 1985
Filed:
May 10, 1983
Appl. No.:
6/493342
Inventors:
Sin Y. Yoo - Silver Spring MD
International Classification:
H05K 500
US Classification:
181146
Abstract:
A ported speaker enclosure is disclosed for extending the low-frequency range of the enclosure and increasing the intensity of the low-frequency range of reproduced sound wherein the size of the enclosure, the locations of the speakers, and the size and locations of the ducted ports are determined by relatively simple relationships based solely on speaker cone dimensions. In one form, a ducted port speaker enclosure is comprised of two bass-range speakers, or woofers, wherein one woofer is located in a predetermined position above the other on the enclosure. An open sector of a plurality of open sectors of the frame at the back of the topmost speaker faces towards the top and an opposite open sector faces towards the bottom of the enclosure of the two woofer system. A sound damping material is added to cover the top and bottom facing sectors of the topmost speaker. Insulation material of predetermined dimensions is affixed to the inside walls of the right and left sides of the enclosure.
