Directive multiway loudspeaker with a waveguide
First Claim
1. A loudspeaker comprising:
- an enclosure having a front portion, two side portions and a back portion defining an inner volume, whereinthe front portion is formed as a waveguide surface and includes at least one driver in the center of the waveguide surface and wherein the front portion is configured to radiate the main acoustic power of the loudspeaker into a direction of a first acoustic axis, and wherein the loudspeaker further comprises;
at least one additional driver attached to the enclosure, wherein the additional driver is attached inside the enclosure such that a sub volume is formed inside the inner volume, wherein the sub volume is limited by;
the driver,spacers between the driver and the front portion,and the front portion of the enclosure, andwherein the loudspeaker further comprises at least one first port, said port being is adapted to open from the sub volume to an ambient volume on at least one of the following;
side portion of the enclosure, andback portion of the enclosure,wherein the at least one first port comprisesat least one resonator acoustically connected dot the sub volume, the resonator being tuned to at least one unwanted resonances of the sub volume.

Abstract
The present invention relates to a loudspeaker including an enclosure having front portion, side portions and back portion defining an inner volume, the front portion is formed as a waveguide surface and includes at least one driver in the center of the waveguide surface and is capable to radiate the main acoustic power of the loudspeaker to ambient volume in direction of first acoustic axis, and an additional driver attached to the enclosure. In accordance with the invention the additional driver is attached inside the enclosure such that a sub volume is formed inside the inner volume, the sub volume limited by the driver, spacers between the driver and the front portion, and the front portion of the enclosure, and at least one port is adapted to open from the sub volume to ambient volume either to side portion or back portion of the enclosure and at least one resonator acoustically connected to the sub volume, the resonator being tuned to at least one of unwanted resonances of the sub volume.
