Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional audio speakers with a single amplifier struggle to provide a broad range of listening experience, often requiring a tradeoff between bass and treble performance, and increasing in size when separate sound units are used to enhance bass performance.
Innovation Solution
A coaxial audio speaker design featuring a bass sound unit with a magnetic-conductive base and a treble sound unit, where the bass vibration audio source point aligns horizontally with the treble vibration audio source point, using a single audio source and a magnetic gap mechanism to optimize sound delivery.
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 audio speaker increases
Solution Approach 1:
The treble sound unit is nested within the bass sound unit, with the treble voice coil assembly positioned inside the bass voice coil assembly. This nested configuration allows both sound units to occupy overlapping spatial volumes, thereby enhancing bass performance through dedicated bass drivers while maintaining a compact overall speaker size.
Solution Approach 2:
The patent utilizes vertical stacking and radial arrangement of sound units along the Z-axis, transitioning from horizontal placement to three-dimensional spatial optimization. The bass sound unit forms an outer ring structure while the treble sound unit is positioned centrally, creating a coaxial configuration that efficiently uses vertical space and reduces the horizontal footprint of the speaker.
2Reliability
If multiple separate sound units are used to achieve broad listening experience, then sound quality is improved, but the complexity of the device increases
Solution Approach 1:
Multiple sound units (bass and treble) are merged into a single integrated assembly where the treble voice coil assembly is positioned within the bass voice coil assembly. This merging approach maintains distinct acoustic functions for broad sound quality while reducing overall structural complexity compared to separate mounted units, as the assemblies share common mounting structures and spatial envelope.
3Device complexity
If a single amplifier is used, then device complexity is reduced, but the range of listening experience is limited
Solution Approach 1:
The single amplifier is designed to drive multiple voice coil assemblies (bass and treble) with different acoustic characteristics. This multi-functional amplifier can adjust output parameters to optimize performance across different frequency ranges and listening scenarios, providing a broad range of listening experiences while maintaining low device complexity through component consolidation.
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
This design allows for a broader range of sound adjustability and reduced size, maintaining balanced bass and treble performance with a single audio source, enhancing the overall listening experience.
Implementation Method 1
a ring-shaped magnet having a first surface and a second surface opposite to the first surface. The first surface may be stationed within the vocal coil movement space, and the ring-shaped magnet may be fixed within the vocal coil movement space and away from the separating wall to form a magnetic gap between the ring-shaped magnet and the separating wall
Implementation Method 2
the vocal coil may extend into the vocal coil movement space and position within the magnetic gap

AI summary
A disclosed coaxial audio speaker may include a treble sound unit and a bass sound unit co-axially surrounding the treble sound unit. The bass sound unit may be in form of a single magnetic gap mechanism and have a magnetic-conductive base. The magnetic-conductive base may be with an auxiliary magnetic adjoining space and a coil movement space adjacent to the auxiliary magnetic adjoining space. A magnet, a vibrating vocal tone diaphragm along with a wiring board may be disposed within the coil movement space. A bass vibration audio source point and a treble vibration audio source point may be at the same horizontal level. Therefore, the size of the audio speaker may be reduced. And the broader electricity adjustability may be achieved as the bass vibration audio source point and the treble vibration audio source point may be horizontally aligned.
