Headphones With Ear Hook Clamping Auricle For Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headphones struggle to balance wearing comfort, stability, and output performance, often compromising on one aspect to achieve others.
Innovation Solution
A headphone design featuring a sound production component and an ear hook with specific geometric configurations, allowing the sound production component to be positioned close to the ear canal without blocking it, and clamping the auricle for improved stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound production component is positioned close to the ear canal to improve output performance, then the output performance is improved, but it may block the ear canal opening and reduce wearing comfort
Solution Approach 1:
The sound production component extends into the concha cavity along the sagittal axis, utilizing the depth dimension of the ear structure. This positional adjustment in the sagittal direction allows the sound production component to be close to the ear canal opening without blocking it, as the ear canal opening faces anteriorly while the concha cavity extends posteriorly. The centroid distance parameter (4-25mm) controls the precise positioning to optimize both sound output and comfort.
Solution Approach 2:
The ear hook structure is differentiated into two portions with distinct functions: the first portion clamps the auricle for stability, while the second portion positions the sound production component. This local differentiation allows each portion to be optimized for its specific function, with the second portion extending anteriorly to position the sound production component without blocking the ear canal.
2Stability of the object's composition
If the ear hook clamps the auricle firmly to improve wearing stability, then the wearing stability is improved, but the wearing comfort may deteriorate due to excessive clamping force
Solution Approach 1:
The design specifies a minimum distance change parameter of at least 1mm between the sound production component and first portion of the ear hook between wearing and non-wearing states. This parameter control ensures adequate clamping force for stability while preventing excessive force that would cause discomfort. The distance parameter serves as a quantitative measure to balance stability and comfort.
Solution Approach 2:
The ear hook is segmented into a first portion for clamping the auricle and a second portion for positioning the sound production component. This segmentation allows the first portion to provide stable clamping while the second portion maintains proper positioning, distributing the mechanical load and preventing excessive force concentration at one point.
3Reliability
If the sound production component extends into the concha cavity to improve sound output, then the output performance is improved, but the structural complexity increases
Solution Approach 1:
The ear hook structure serves multiple functions: it clamps the auricle for stability, positions the sound production component close to the ear canal, and supports the sound production component's extension into the concha cavity. This multi-functionality reduces the need for additional separate components, maintaining structural simplicity while achieving the desired sound output performance.

AI summary
Embodiments of the present disclosure provide a headphone including a sound production component and an ear hook. The ear hook includes a first portion and a second portion connected in sequence. The first portion being hooked up between an ear auricle and a head of a user, and the second portion is configured to be hang between an auricle of a user and a head of the user, the second portion extends toward a front outer side of the auricle, connects with the sound production component, and is configured to place the sound production component at a position close to an ear canal without blocking an opening of the ear canal, and at least a portion of the sound production component is inserted into an concha cavity. The sound production component and the first portion of the ear hook clamp the auricle in a wearing state.
