Abstract
Coiled Exponential Bass Midrange Horn Loudspeakers which are each characterized by a rigid cabinet of selected size having a sealed air chamber in the base thereof for receiving a low frequency speaker, or driver, and a coiled or convoluted, exponentially flared sound passage extending from the air chamber to the top of the cabinet. In a most preferred embodiment, a high frequency horn is mounted in the cabinet near the open top to extend the audio range of the loudspeaker system. The combination of a low frequency driver and a high frequency horn separated by a continuously exponentially expanding or flared, coiled or convoluted, multi-tapered sound passage chamber eliminates the need for a midrange speaker or horn.
Claims22
A coiled exponential bass/midrange horn loudspeaker comprising enclosure means having an open top, said enclosure means adapted for mounting in a selected location for use as a loudspeaker;
- flared sound chamber means provided in said enclosure means in convoluted relationship, said flared sound chamber means defining an exponentially expanding sound passage inside said enclosure means;
- a substantially sealed air chamber provided in said enclosure means and an aperture provided in said air chamber, said aperture communicating with said flared sound chamber means;
- and low frequency driver means provided in said air chamber adjacent to said aperture, for generating sound and projecting the sound through said flared sound chamber means and from said open top of said enclosure means.
A coiled exponential bass/midrange horn loudspeaker comprising enclosure means having a bottom panel, side panels upward-standing from said bottom panel in spaced relationship, a front panel upward-standing from said bottom panel for closing one side of said side panels and a rear panel upward-standing from said bottom panel for closing the opposite side of said side panels and defining an open top;
- a flared sound chamber provided in said enclosure means, said flared sound chamber disposed between said side panels and extending through said enclosure means in convoluted, stacked, exponentially expanding relationship;
- a substantially sealed air chamber provided in said enclosure means adjacent to said bottom panel and a loading aperture provided in said air chamber, said air chamber communicating with the bottom end of said flared sound chamber through said loading aperture;
- and low frequency driver means mounted in said air chamber adjacent to said loading aperture, for generating sound and projecting the sound through said loading aperture and said flared sound chamber and from said open top of said enclosure means.
A coiled exponential bass/midrange horn loudspeaker comprising an enclosure having a bottom panel, side panels upward-standing from said bottom panel in spaced relationship, a front panel upward-standing from said bottom panel for closing one side of said side panels and a rear panel upward-standing from said bottom panel for closing the opposite side of said side panels and defining an open top;
- a flared sound chamber provided in said enclosure with said side panels defining opposite walls of said flared sound chamber and said flared sound chamber arranged in convoluted, stacked relationship and extending through said enclosure in exponentially expanding relationship;
- a substantially sealed air chamber provided in said enclosure adjacent to said bottom panel and a loading aperture provided in said air chamber, said air chamber communicating with the bottom end of said flared sound chamber through said loading aperture;
- and a low frequency driver mounted in said air chamber adjacent to said loading aperture, for generating sound and projecting the sound through said loading aperture and said flared sound chamber and from said open top of said enclosure.
