LOUDSPEAKER WITH REDUCED AUDIO COLORATION CAUSED BY REFLECTIONS FROM A SURFACE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240048895 titled 'LOUDSPEAKER WITH REDUCED AUDIO COLORATION CAUSED BY REFLECTIONS FROM A SURFACE
Simplified Explanation
The abstract describes a patent application for loudspeakers that aim to reduce comb filtering effects perceived by a listener. This can be achieved through two methods:
1) Moving transducers closer to a sound reflective surface: The transducers can be adjusted vertically or rotated to bring them closer to a baseplate, tabletop, or floor. This adjustment helps in reducing comb filtering effects.
2) Guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface: This is done using horns and openings that are at a prescribed distance from the reflective surface. By reducing the distance between the reflective surface and the point where sound is released, the reflected path becomes shorter, thereby reducing comb filtering effects caused by delayed reflected sounds.
Potential applications of this technology:
- Home audio systems
- Professional audio systems in concert halls or theaters
- Public address systems in large venues
- Automotive audio systems
Problems solved by this technology:
- Comb filtering effects caused by reflected sounds can distort the audio quality and affect the listener's experience. This technology aims to reduce these effects, allowing for clearer and more accurate sound reproduction.
Benefits of this technology:
- Improved audio quality: By reducing comb filtering effects, the loudspeakers provide a more accurate and natural sound reproduction.
- Versatile placement options: The loudspeakers can be placed on reflective surfaces without severe audio coloration caused by reflected sounds, providing flexibility in installation.
- Enhanced listening experience: The reduction of comb filtering effects leads to a more immersive and enjoyable listening experience for the listener.
Original Abstract Submitted
loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. the reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.
