Dual Speaker Earphone with Pivotable Hanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones lack adjustable mechanisms for optimal fit and comfort, with limited adjustability in position and orientation, and often feature only a single speaker element.
Innovation Solution
An adjustable dual speaker element earphone design featuring a pivotably connected speaker element with a rotatable knob and a hanger bar that can be adjusted to fit comfortably on the ear, allowing for precise positioning of both speaker elements within the ear canal and on the ear's external curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single speaker element is used, then the device complexity is reduced, but the sound reproduction fidelity deteriorates
Solution Approach 1:
The earphone is divided into two separate speaker elements: a first speaker element with a first transducer for producing first sound, and a second speaker element with a second transducer for producing second sound. This segmentation allows each transducer to be optimized for specific frequency ranges, improving overall sound reproduction fidelity while maintaining manageable device complexity through modular design
2Adaptability or versatility
If fixed position speaker elements are used, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The speaker elements are connected to the bridge via pivotable joints instead of fixed connections. The first speaker element is pivotably connected to the first end of the bridge, and the second speaker element is pivotably connected to the second end of the bridge. This dynamic connection allows users to adjust the position and orientation of each speaker element independently to achieve optimal fit and comfort for different ear shapes and sizes
Solution Approach 2:
The second speaker element is designed to fit within or alongside the first speaker element structure, with the second housing sized and configured to fit at least partially into the cavum concha. This nested arrangement allows both speaker elements to coexist in a compact configuration while maintaining individual adjustability
3Reliability
If gravity-dependent holding mechanism is used, then the device complexity is reduced, but the reliability deteriorates
Solution Approach 1:
A hanger bar is introduced as a counterbalancing structure that extends from the bridge and is configured to rest upon a part of the listener's ear. The hanger bar acts as a mechanical counterweight that provides downward force to hold the speaker elements securely in position within the ear canal, compensating for any gravitational forces and ensuring stable positioning regardless of head orientation or movement

AI summary
An adjustable, dual speaker element earphone. One of the speaker elements is sized to fit into the cavum concha of the listener's 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.
