Slim Loudspeaker With Separate Cavity Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeakers face a trade-off between achieving good sound quality and compact size, as traditional arrangements of sound transducers often result in bulky designs that sacrifice either sound quality or size.
Innovation Solution
The loudspeaker design features sound transducers arranged in separate cavities with narrow slits that direct sound in specific directions, allowing for a slim profile while maintaining sound quality, with optional tilting and acoustic volume separation to minimize distortion and resonance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound transducers are arranged to emit sound perpendicular to the front facing side of the loudspeaker housing, then sound quality is improved, but the loudspeaker becomes bulky
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional front-facing sound transducer arrangement to side-emitting transducers. The sound transducers are positioned such that they emit sound in a direction substantially parallel to the front facing side of the housing, utilizing the side dimension of the housing to achieve compact front profile while maintaining sound quality through optimized transducer orientation and separate cavity design
2Volume of moving object
If sound transducers are arranged in separate cavities with narrow slits, then the loudspeaker becomes compact, but sound isolation between cavities is improved
Solution Approach 1:
The patent applies segmentation by dividing the loudspeaker into separate cavities, each housing specific sound transducers. The first cavity contains first sound transducers and the second cavity contains second sound transducers, with each cavity having its own narrow slit opening. This segmentation isolates sound paths between different frequency ranges while maintaining compact overall size through efficient space utilization

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves a compact, powerful loudspeaker with a rich sound spectrum and minimized distortion, enabling a more versatile and slim housing shape without compromising sound quality.
Implementation Method 1
the sound transducers, depending on the frequency range in which they emit sound, may emit in different directions
Implementation Method 2
the slits will act as means to direct the sound in a definite direction

AI summary
The present invention describes a loudspeaker comprising a housing and a plurality of sound transducers arranged inside said housing, where the housing has two sides arranged on either side of a x-y plane with a mutual distance between said sides measured along a z-axis orthogonal to the x-y plane, and a front facing side and a rear facing side, and a top and a bottom, wherein a. A first sound transducer is arranged inside a first cavity inside said loudspeaker housing, where said first cavity has a narrow first slit in the y-direction provided in the rear facing side, where said first slit has a width z1 in the z-direction, and a length y1 in the y-direction where the length y1 in the y-direction is larger than the width z1 in the z-direction; b. A second sound transducer is arranged inside a second cavity inside said loudspeaker housing, separate from said first cavity, and where said second cavity is provided with a narrow second slit in the y-direction provided in the front facing side, where said second slit has a width z2 in the z-direction, and a length y2 in the y-direction, where the length y2 in the y-direction is larger than the width z2 in the z-direction.
