Speaker Pitch-Adjustment Ring for Sound Zone Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small speakers, such as earphones, face challenges in simultaneously achieving high-quality output for both high-pitched and low-pitched sounds due to their design limitations.
Innovation Solution
A speaker design featuring a pitch-adjustment ring with alternately arranged permeable and non-permeable sections, coupled with a toggle structure, allows for rotation to adjust the output between high-pitched and low-pitched sound zones by aligning permeable sections with specific sound zones, enhancing sound quality based on user demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a speaker uses a single sound-producing unit to maintain small volume, then the device size is reduced, but the sound quality for both high-pitched and low-pitched sounds cannot be simultaneously optimized
Solution Approach 1:
The speaker is divided into distinct high-pitched sound zone and low-pitched sound zone with separate sound-producing units. The partition wall separates these zones, allowing each unit to optimize its sound production independently, thus achieving both small overall size and specialized sound quality for different pitch ranges.
Solution Approach 2:
A rotatable pitch-adjustment ring with alternating permeable and non-permeable sections is introduced to dynamically adjust the acoustic coupling between high-pitched and low-pitched sound zones. By rotating the ring to different positions, users can control the sound output balance between high and low pitches, providing adaptability without increasing device size.
2Adaptability or versatility
If the speaker isolates high-pitched and low-pitched sound zones completely, then sound quality for each zone is optimized, but the ability to adjust output balance between zones is lost
Solution Approach 1:
The pitch-adjustment ring serves as an intermediary mechanism between the isolated high-pitched and low-pitched sound zones. The ring's permeable sections allow controlled acoustic coupling when needed, while non-permeable sections maintain isolation. This intermediary structure enables users to adjust the output balance between zones without compromising the fundamental isolation that optimizes each zone's sound quality.
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 enables convenient tuning of sound output for high-pitched and low-pitched sounds, improving overall sound quality and user experience by isolating and adjusting sound zones effectively.
Implementation Method 1
The pitch-adjustment ring is rotatable to align the at least one permeable section with the high-pitched sound zone or the low-pitched sound zone
Implementation Method 2
The partition wall is coupled with the frame to isolate a high-pitched sound zone from a low-pitched sound zone

AI summary
A speaker includes a frame, a partition wall and a pitch-adjustment ring. The partition wall is coupled with the frame to isolate a high-pitched sound zone from a low-pitched sound zone. A pitch-adjustment ring is rotatably coupled to the frame and has at least one permeable section and at least one non-permeable section. The pitch-adjustment ring is rotatable to align the at least one permeable section with the high-pitched sound zone or the low-pitched sound zone.
