Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker designs offer fixed sound quality, limiting their application and requiring inconvenient structural modifications for sound quality adjustments.
Innovation Solution
A speaker back cover with adjustable channel path length, comprising a first and second casing part that can move or rotate relative to each other, allowing users to adjust sound quality by altering the channel path from the resonance space to the outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the speaker back cover structure is made fixed, then the manufacturing simplicity and structural stability are improved, but the sound quality adaptability deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed back cover structure into a movable one. The back cover includes a first casing part and a second casing part that can relatively move or rotate with respect to each other, allowing the channel path length to be adjusted. This dynamic structure enables the speaker to adapt sound quality while maintaining manufacturing simplicity through modular design.
2Adaptability or versatility
If the speaker back cover is modified by adding absorbing foam or other components, then the sound quality can be changed, but the operational convenience deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the back cover into a first casing part and a second casing part that can independently move or rotate. This segmentation allows users to adjust sound quality by simply moving the parts relative to each other, making the operation convenient without requiring complex modifications like adding absorbing foam.
3Adaptability or versatility
If the channel path length is made adjustable, then the sound quality adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent resolves the complexity issue by implementing a simple dynamic mechanism where the first and second casing parts can relatively move or rotate. This straightforward dynamic structure achieves adjustable channel path length without introducing complex mechanisms, thereby maintaining low device complexity while improving sound quality adaptability.
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
Enables simple and convenient adjustment of sound quality by manipulating the first and second casing parts, enhancing user control over speaker performance.
Implementation Method 1
The speaker back cover includes a first casing part and a second casing part. The first casing part and the second casing part are relatively movably connected and form a resonance space.

AI summary
A speaker includes a speaker driver and a speaker back cover. The speaker driver has a basket at its rear side. The speaker back cover is sealed and fixed to the basket and includes two casing parts which are relatively movably or rotatably connected and form a resonance space at the rear side of the speaker driver. Each casing part has a channel structure with an opening. The two channel structures are connected so that the resonance space is connected to the outside of the speaker back cover through it. The two casing parts can be moved or rotated relative to each other to adjust a channel path length of the two channel structures from their inner opening to their outer opening.
