Rotatable Headphone Sound Units for DJ Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headphones are difficult for DJs to wear in non-standard positions, such as with one earpiece on the ear and the other held by the chin or at the back of the head, due to limited rotation range, which affects stability and requires larger storage space.
Innovation Solution
A headphone design with rotatable sound-emitting units connected to a headband via adjustable connectors, allowing a range of 0 to 90 degrees or 0 to 45 degrees, enabling flexible positioning and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotation range of the sound-emitting unit is set to 90 degrees, then the adaptability for different wearing positions is improved, but the thickness of the headphone increases requiring larger storage space
Solution Approach 1:
The patent implements a rotatable sound-emitting unit that can dynamically adjust its orientation. The rotating mechanism allows the sound-emitting unit to change its angular position relative to the headband, enabling the headphone to adapt between normal wearing position and alternative positions (such as DJ style wearing) without increasing the overall thickness when stored in the minimal 0-degree configuration.
2Volume of moving object
If the rotation range of the sound-emitting unit is restricted to less than 90 degrees, then the storage space requirement is reduced, but the stability when worn in non-standard positions deteriorates
Solution Approach 1:
The patent employs an adjustable rotation range mechanism that can be configured to provide sufficient rotational freedom for stable non-standard wearing positions while limiting the maximum rotation angle to prevent excessive thickness. The rotation range parameter is optimized to balance between achieving stable alternative wearing positions and maintaining a compact form factor for storage.
3Ease of operation
If the sound-emitting unit is made rotatable, then the ease of operation for adjusting wearing position is improved, but the device complexity increases
Solution Approach 1:
The patent divides the headphone into modular components: a fixed headband and a rotatable sound-emitting unit connected through a specialized connector. This segmentation allows the rotating function to be isolated to a specific component, making the adjustment operation simple for the user while containing the mechanical complexity within a dedicated rotating connector assembly that can be independently manufactured and assembled.

AI summary
A headphone includes: a headband (2); at least one sound-emitting unit including a sound emitter located therein; at least one connector (4) connecting the sound-emitting unit to the headband (2) such that the sound-emitting unit is rotatable around a rotation axis along an up-down direction; and at least one adjuster (5) configured to adjust a rotation range of the sound-emitting unit.
