Multi-ring coaxial audio speaker with nested bass units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional audio speakers with a single amplifier struggle to provide a broad range of listening experience, requiring a tradeoff between bass and treble performance, and increasing size when separate sound units are used to enhance bass performance.
Innovation Solution
A multi-ring coaxial audio speaker design using multiple bass sound units co-axially arranged around a treble sound unit, with vibration source points aligned at the same horizontal level, allowing for improved electrical adjustability and reduced size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate sound units are used to enhance bass performance, then bass performance is improved, but the size of the speaker increases
Solution Approach 1:
The patent implements a nested structure where the first bass sound unit is positioned inside the second bass sound unit, and the treble sound unit is positioned inside the first bass sound unit. This nested arrangement allows multiple sound units to occupy overlapping spatial volumes, enhancing bass performance through multiple bass units while maintaining a compact overall speaker size.
2Adaptability or versatility
If multiple separate sound units are used to provide broad listening experience, then listening experience is improved, but the space occupied inside the speaker increases
Solution Approach 1:
The nested arrangement of sound units (treble unit inside first bass unit, which is inside second bass unit) enables multiple sound units to be integrated within a compact internal space. This provides broad listening experience through separate bass and treble units without proportionally increasing the internal space occupation.
Solution Approach 2:
The patent utilizes co-axial arrangement along a central axis, organizing sound units in a radial and axial configuration rather than a planar layout. This three-dimensional spatial organization maximizes the use of internal space, allowing multiple sound units to be packed efficiently while maintaining broad listening experience coverage.
3Device complexity
If a single amplifier is used, then device simplicity is maintained, but bass and treble performance tradeoff occurs
Solution Approach 1:
The patent segments the sound production function into distinct bass sound units and a treble sound unit, each with dedicated vibration sources and diaphragms. This segmentation allows independent optimization of bass and treble performance characteristics, achieving high-quality sound output across different frequency ranges while maintaining a relatively simple single-amplifier architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a broader range of listening experience with enhanced bass and treble performance without increasing the size of the speaker, offering improved electrical adjustability and sound output.
Implementation Method 1
The first bass sound unit may include a ring-shaped magnet, a magnetic-conductive ring, a vibrating vocal tone diaphragm, and a voice coil
Implementation Method 2
a ring-shaped magnet, a magnetic-conductive ring, a vibrating vocal tone diaphragm, and a voice coil

AI summary
A disclosed multi-ring coaxial audio speaker may include a treble sound unit, a first bass sound unit co-axially surrounding the treble sound unit, and a second bass sound unit co-axially surrounding the first bass sound unit. The first bass sound unit, the second bass sound unit, and the treble sound unit may be co-axially disposed with respect to each other. Bass vibration audio source points and a treble vibration audio source point may be at the same horizontal level, to achieve the broader electrical adjustability. The size of the audio speaker may be reduced as well.
