US 5,673,329 A · Omni-directional loudspeaker system

Abstract

A loudspeaker system includes a flexible compressible tube having a woofer mounted at one end with its cone directed outward, and a vented baffle mounted at the other end. A first sound dispersion element is mounted with its apex facing the cone of the woofer and a midrange speaker is mounted in the base of the dispersion element with its cone facing away from the tube. A second sound dispersion element is mounted with its apex facing the cone of the midrange speaker, and at least one tweeter is mounted on the base of the second sound dispersion element with its cone facing away from the tube. According to one embodiment, a plurality of tweeters are mounted in an enclosure mounted on the base of the second dispersion element. According to another embodiment, a single tweeter is mounted in the base of the second dispersion element and a third dispersion element is mounted with its apex facing the cone of the tweeter. According to a preferred embodiment of the invention, a pair of tubes are coupled to each other at their baffles to form a stereo speaker system. A fabric sleeve having a graphic display which may include an advertisement fits over the tubes. In order to enhance the aesthetic appearance of the speaker system and to protect the speakers from the environment, a fabric covering is optionally provided over the speakers and dispersion elements.
