Clip-On Earphone Rigid-Flexible Housing for Comfort and Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip-on earphones face a challenge in balancing comfort and support, with rigid materials providing inadequate support and flexible materials offering poor structural integrity.
Innovation Solution
A clip-on earphone design featuring a sound generation portion with a first rigid housing and a second rigid housing enclosing a first flexible member, where the flexible member covers the outer wall of the second rigid housing to reduce direct skin contact, enhancing comfort while maintaining structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid material is used for the housing, then structural support is improved, but wearing comfort deteriorates
Solution Approach 1:
The housing is divided into two distinct parts: a rigid first housing providing structural support and a flexible second housing covering the contact portion. This segmentation allows each part to perform its specific function optimally without compromise.
Solution Approach 2:
Different parts of the housing have different material properties: the first housing uses rigid material for structural integrity, while the second housing uses flexible material for comfort during skin contact. This local differentiation resolves the contradiction between strength and comfort.
2Object-affected harmful factors
If a flexible material is used for the housing, then wearing comfort is improved, but structural support deteriorates
Solution Approach 1:
The housing is segmented into a rigid first housing that maintains structural support and a flexible second housing that provides comfort. The flexible portion is specifically positioned only where skin contact occurs, preserving overall structural integrity.
Solution Approach 2:
The flexible material is applied locally only to the portion of the housing that contacts the skin, while the rest of the housing maintains rigid structure. This localized application ensures comfort without compromising overall structural support.
3Object-affected harmful factors
If the flexible member covers the entire outer wall of the rigid housing, then wearing comfort is improved, but internal space utilization deteriorates
Solution Approach 1:
The flexible second housing covers only the necessary contact portions of the first housing outer wall, rather than the entire surface. This partial coverage achieves adequate comfort while preserving internal space for acoustic components.
Solution Approach 2:
The flexible material is applied selectively to specific local areas where skin contact occurs, rather than uniformly across the entire housing. This localized approach maintains comfort functionality while maximizing internal space utilization for acoustic components.

AI summary
The present disclosure relates to a clip-on earphone. The clip-on earphone includes a sound generation portion, an abutting portion, and an ear hook connecting the sound generation portion and the abutting portion. The abutting portion and the sound generation portion form a clamping state to clamp and wear the clip-on earphone on an auricle of a wearer. The sound generation portion includes a first housing and a sound generation assembly. The first housing includes a first rigid housing connected to the ear hook, a second rigid housing for facing a concha cavity of the wearer when worn, and a first flexible member for contacting the concha cavity of the wearer. The first rigid housing and the second rigid housing enclose to form a first accommodating cavity. The first flexible member covers an outer wall of the second rigid housing. The sound generation assembly is disposed in the first accommodating cavity. The first housing includes a sound outlet hole. A sound wave generated by the sound generation assembly is capable of propagating to the wearer through the sound outlet hole.
