Concha-Reflective Clip Earphone Structure for Higher Sound Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clipping earphones suffer from insufficient volume and poor sound quality due to their compact size, which limits the efficiency of sound production and output.
Innovation Solution
The design incorporates a sound-production portion positioned within the concha cavity with a sound outlet hole partially blocked by the inner wall, utilizing the concha cavity as a reflection wall to enhance sound volume through interference and diffraction, and includes an ear hook that bypasses the antihelix and helix for stable wearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clipping earphone is made compact to fit the concha cavity, then the device can be comfortably worn and safely used, but the sound volume and sound quality become insufficient
Solution Approach 1:
The concha cavity serves as an intermediary acoustic chamber between the sound outlet hole and the ear canal. By positioning the sound-production portion within the concha cavity and utilizing its inner wall as a reflection surface, the system leverages the existing ear anatomy to amplify and direct sound waves, effectively increasing sound volume without increasing the physical size of the earphone itself.
Solution Approach 2:
The sound outlet hole is designed with a curved outer end surface that overlaps with the concha cavity's inner wall in a specific arcuate region. This curved geometry enables the sound waves to be reflected and focused toward the ear canal while maintaining a compact form factor that fits comfortably within the concha cavity.
2Power
If the sound outlet hole is partially blocked by the concha cavity wall, then sound volume is enhanced through reflection, but the structure becomes more complex
Solution Approach 1:
The concha cavity serves multiple functions simultaneously: it acts as the housing for the sound-production portion, provides a reflection surface for sound waves, and serves as the structural framework for positioning the sound outlet hole. By leveraging the existing ear anatomy, the design avoids adding separate structural elements, thereby enhancing sound volume without proportionally increasing device complexity.

AI summary
Embodiments of the present disclosure provide a clipping earphone, comprising a sound-production portion disposed within a concha cavity of a wearer and in contact with an inner wall of the concha cavity. The sound-production portion includes a shell, the shell forming an accommodation cavity; a sound-production component, accommodated in the accommodation cavity; a sound outlet hole, disposed on the shell and configured to export a sound generated by the sound-production component, wherein a portion of the sound outlet hole is blocked by the inner wall of the concha cavity; an abutting portion, configured to abut against the back of an ear of a wearer; and an ear hook, configured to bypass an antihelix and helix of the wearer to connect the sound-production portion and the abutting portion.
