Filed:

Sep 9, 2011

Appl. No.:

13/228554

Inventors:

Michael Weidner - Oshkosh WI, US

International Classification:

A47B 81/06

US Classification:

181199, 181198, 181148, 181156

Abstract:

The present invention relates to speaker enclosures utilizing the golden ratio geometrically throughout the design to reduce reflections, resonance and phase shifting, and to improve the transient response. Enclosures can be box-shaped, trapezoidal, suspended or otherwise configured. The enclosure has a driver wall, a baffle and a rear wall. The driver wall and baffle define a front chamber, and the baffle and rear wall define a rear chamber. The volumetric ratio between the rear chamber and front chamber can be approximately 0. 6. The rear chamber also can have braces or dividers that segment the chamber into a central portion and two side portions. The volumetric ratio between the side portions and the central portion can be approximately 0. 6. Ports of various configurations are provided. Braces can be used in conjunction with the ports to diffuse the incoming air.
