Self-Adjusting Headphone Speaker Mount for Uniform Ear Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Headphones with speaker units often fail to fit perfectly with users' ears or skin, leading to uneven pressure distribution and discomfort due to high pressure in some areas and low pressure in others, reducing user experience.
Innovation Solution
A headphone design featuring studs on the speaker unit that fit into corresponding holes on the speaker fastener, allowing the unit to adjust its position for uniform contact with the user's ear or skin, combined with a rotating mechanism for play mode adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the speaker unit is fixed in the headphone, then the structure is simple and easy to manufacture, but the speaker unit cannot fit perfectly with the user's ear or skin, resulting in uneven pressure distribution
Solution Approach 1:
The patent applies the dynamics principle by making the speaker unit adjustable within the headphone structure. The speaker unit can move between a first position for supra-aural contact and a second position for bone conduction contact, allowing the system to adapt to different user needs and anatomical variations while maintaining manufacturing simplicity
Solution Approach 2:
The patent implements multi-functionality by enabling the same speaker unit to serve multiple contact modes (supra-aural and bone conduction) and accommodate different user preferences. The adjustable mechanism allows a single headphone design to fit various user anatomies without requiring multiple specialized products
2Area of stationary object
If the speaker unit is made larger to ensure better contact, then the contact area increases, but the pressure distribution becomes more uneven and user comfort decreases
Solution Approach 1:
The patent uses dynamics to allow the speaker unit to adjust its position dynamically. By enabling movement between different contact positions, the system can optimize the contact area for each user's specific anatomy, distributing pressure evenly across the appropriate area rather than forcing a fixed large contact area that causes discomfort
3Adaptability or versatility
If the speaker unit is adjusted to fit different user ears, then the fit precision improves, but the device complexity increases
Solution Approach 1:
The patent applies dynamics with a relatively simple adjustment mechanism that allows the speaker unit to move between predefined positions. This provides fit precision for different user types without requiring complex continuous adjustment systems, balancing adaptability with manufacturing complexity

AI summary
A headphone with automatic position adjustment, comprising a speaker fastener, a speaker unit and an ear hook. There is a first accommodation space with at least one opening on the speaker fastener, at least two through holes on side walls of the speaker fastener, and at least two studs on side walls of the speaker unit in the first accommodation space; when the speaker unit is assembled into the first accommodation space, the studs are respectively clamped in the corresponding holes, and can move freely. In the present disclosure, the speaker unit is fixed in the first accommodation space of the speaker fastener by the stud and the hole. When in use, the user's ears or skin will exert a pressure on the speaker unit. Since the stud can move freely in the hole, the speaker unit will adjust its position automatically according to the pressure.
