Adjustable Dual Speaker Earphone with Rotating Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones lack adjustable mechanisms for optimal positioning and comfort, particularly in dual speaker element designs, which restricts the ability to customize sound reproduction for individual ear shapes and sizes.
Innovation Solution
An adjustable dual speaker element earphone design featuring a pivotable larger speaker element and a smaller in-ear speaker element, connected via a hanger bar with a rotatable knob, allowing for precise adjustment of the speaker elements' position and alignment with the ear, including a hanger bar that rests on the ear's external curvature to exert force independently of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dual speaker element design is used, then sound reproduction quality is improved, but device complexity increases
Solution Approach 1:
The earphone is divided into two distinct speaker elements: a larger speaker element for external sound reproduction and a smaller in-ear speaker element for direct ear canal sound delivery. This segmentation allows each speaker to be optimized for its specific function, improving overall sound reproduction quality while managing complexity through functional separation
Solution Approach 2:
The smaller in-ear speaker element is positioned within the housing of the larger speaker element, creating a nested configuration. The smaller speaker fits into the cavum concha while the larger speaker remains external, allowing both elements to coexist in a compact arrangement that manages device complexity
2Adaptability or versatility
If adjustable mechanisms are added, then adaptability to different ear shapes is improved, but device complexity increases
Solution Approach 1:
The bridge connecting the two speaker elements incorporates a rotatable knob that allows dynamic adjustment of the relative positions and orientations of the speaker elements. This mechanical adjustment mechanism enables the device to adapt to different ear shapes and sizes while maintaining a relatively simple overall structure through a single degree of freedom adjustment
Solution Approach 2:
The rotatable knob on the bridge serves multiple functions: it adjusts the distance between speaker elements, modifies their relative orientations, and enables the device to fit various ear anatomies. This single mechanism provides universal adaptability across different users without requiring multiple separate adjustment systems

AI summary
An adjustable, dual speaker element earphone. One of the speaker elements is sized to fit into the cavum concha of the listeners ear and the other element is not. A hinged joint may allow the larger speaker element may be rotated about a vertical axis of the hinged joint so that the larger speaker element can be rotated towards or away from the listener's ear. The speaker elements may be connected such that sounds produced by both speaker elements emanate from different respective sound openings defined in a surface of the smaller speaker element. Also, one or both of the speaker elements may be operably connected to a hanger bar that is sized and configured to rest on an upper portion of the listener's ear.
