Earpiece Attachment with Ear Compression for Ambient Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earpieces that occlude the ear canal significantly attenuate ambient sounds, making it difficult for users to localize sounds in their environment, and non-occluding earpieces with small form factors often struggle to produce adequate volume due to size and shape variations in human ears.
Innovation Solution
The design of an earpiece with a housing and a projection that compresses the ear to position the transducer in the cavum conchae without blocking the ear canal, allowing for sound transmission while enabling the user to hear environmental sounds, featuring a retention member and a compression device that securely attaches to the ear using elastic or spring-loaded mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If occluding earpieces are used to block the ear canal, then sound transmission from the audio source is improved, but ambient sound awareness deteriorates
Solution Approach 1:
The earpiece is divided into separate functional components: a housing containing the transducer positioned in the concha, and a retention member that secures the device without blocking the ear canal. This segmentation allows the audio transmission function to be separated from the occlusion function, enabling sound delivery while maintaining ambient awareness.
Solution Approach 2:
The transducer is extracted from the traditional in-ear canal position and relocated to the concha area. This extraction removes the need to block the ear canal for effective sound transmission, as the transducer can deliver audio signals directly to the ear without occluding the ear canal entrance.
2Object-affected harmful factors
If non-occluding earpieces with small form factor are used to maintain ambient awareness, then environmental sound perception is improved, but volume output deteriorates
Solution Approach 1:
The sound delivery mechanism transitions from the traditional intra-ear canal dimension to the external concha dimension. By positioning the transducer in the concha and utilizing the natural acoustics of the ear structure, the system achieves effective volume output without requiring in-ear canal insertion, thus maintaining ambient sound awareness.
3Adaptability or versatility
If earpieces are designed to fit various ear sizes and shapes, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The retention member incorporates elastic or spring-loaded mechanisms that dynamically adapt to different ear shapes and sizes. This dynamic design allows the retention member to exert appropriate securing force across various anatomical variations without requiring multiple discrete size options or complex adjustment mechanisms.
Solution Approach 2:
The retention member's elastic properties and spring forces are optimized to provide consistent securing performance across a range of ear geometries. By carefully selecting material properties and mechanical characteristics, the device achieves broad adaptability while maintaining a simple, unified structure.

AI summary
Devices for attaching earpiece to a user's ear are described herein. In one embodiment, an earpiece that is removably attachable to an ear of a user can include a housing that has a proximal end portion and a distal end portion. A transducer may be positioned, for example, at the proximal portion of the housing, and a retention member can be elastically coupled to the distal portion of the housing. The retention member and the housing can be configured to compress a portion of the user's ear therebetween in a manner that positions the proximal end portion of the housing in a vestibule of the ear adjacent an entrance to the auditory canal of the user's ear when the earpiece is attached to the user's ear.
