Nested Audio Speakers Sharing One Magnet for Compact Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio speaker systems require multiple dedicated magnets for each speaker component, leading to increased size and complexity, which is inefficient for compact electronic devices.
Innovation Solution
Integrating multiple speakers with one speaker positioned within another, sharing a magnet assembly, allowing the inner speaker to utilize the magnetic field of the outer speaker, thereby reducing the need for its own magnet and minimizing the overall footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple dedicated magnets are used for each speaker component, then each speaker can function independently and reliably, but the overall size and complexity of the speaker assembly increases
Solution Approach 1:
The patent combines multiple speaker components (tweeter and woofer) into a single integrated assembly where they share common structural elements including a single magnet assembly. The tweeter is positioned within the woofer structure, and both speakers utilize the same magnet, reducing the total component count and assembly size while maintaining functional independence of each speaker type
Solution Approach 2:
The tweeter speaker component is nested within the woofer speaker structure. The tweeter assembly fits inside the central opening of the woofer's magnet assembly, creating a compact nested configuration where the smaller tweeter unit is housed within the larger woofer unit, maximizing space efficiency
2Power
If multiple dedicated magnets are used for each speaker component, then each speaker maintains optimal magnetic field strength, but the device complexity and number of components increases
Solution Approach 1:
The patent merges the magnet assemblies of multiple speakers into a single shared magnet structure. The tweeter and woofer both utilize the same permanent magnet, which is positioned to provide magnetic flux to both voice coils. This reduces the number of magnets from two to one, simplifying the device while maintaining sufficient magnetic field strength for both speakers through strategic positioning
Solution Approach 2:
The single magnet assembly serves multiple functions by providing the magnetic field for both the tweeter and woofer speakers simultaneously. This universal magnet structure replaces what would traditionally require separate dedicated magnets for each speaker, reducing component count and assembly complexity
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 configuration reduces the number of components and overall size of the speaker assembly while maintaining efficient sound production across different frequency ranges.
Implementation Method 1
the voice coil may sense the magnetic flux from the permanent magnet
Implementation Method 2
when receiving an alternating electrical current, the voice coil may form an electromagnet
Implementation Method 3
One of the audio speakers (e.g., the second audio speaker) includes a space, or void, to receive, or at least partially receive, the other audio speaker (e.g., the first audio speaker) in the space

AI summary
A speaker assembly includes multiple audio speakers in which an audio speaker is designed to receive, or at least partially receive, in an additional audio speaker. The audio speaker may include a magnet (e.g., permanent magnet) that includes an opening into which a voice coil of the additional audio speaker is positioned. The voice coil of the additional audio speaker is close enough in proximity to the magnet such that the voice coil may sense the magnetic field from the magnet may and magnetically attract to or repel the voice coil, based on a polarity of the voice coil when the voice coil forms an electromagnet. In this regard, the audio speakers may share the magnet, as one of the audio speaker does not require its own dedicated, permanent magnet.
