Headphone Guide Portions and Sliders for Smooth Speaker Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headphones have complex structures for adjusting the relative positional relationship between speakers and a headband, leading to difficult maintenance, increased part count, and troublesome position adjustment, with sudden force changes causing catching during adjustment.
Innovation Solution
A headphone design featuring an outer arc-shaped headband with strip-shaped guide portions and inner arc-shaped head pads, utilizing sliders with insertion holes and pressing portions to facilitate smooth adjustment and reduce part count, allowing easy maintenance and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both the speakers and the headband are provided with a structure for slidably holding the speakers with respect to the headband, then the relative positional relationship between the speakers and the headband can be adjusted, but the configuration becomes complicated and maintenance becomes troublesome
Solution Approach 1:
The patent extracts the sliding adjustment structure from the headband and concentrates it entirely in the speakers. The headband is simplified to only have guide portions, while the speakers contain the slider, slit, and elastic member components. This extraction resolves the contradiction by maintaining adjustability while significantly reducing headband complexity and facilitating maintenance.
2Adaptability or versatility
If both the speakers and the headband are provided with a structure for slidably holding the speakers with respect to the headband, then the relative positional relationship can be adjusted, but the number of parts increases
Solution Approach 1:
The patent merges the sliding mechanism components (slider, slit, elastic member) into a single location - the speaker. Instead of distributing sliding structures across both the headband and speakers, all sliding functionality is consolidated in the speaker, reducing the total number of parts while maintaining full adjustability.
3Reliability
If the slider holding portion holds the slider at a plurality of positions, then the slider can be held strongly, but the force holding the slider suddenly changes when moved, resulting in catching
Solution Approach 1:
The patent employs an elastic member that provides dynamic, continuous force throughout the slider's movement range. Instead of fixed discrete holding positions that cause sudden force changes, the elastic member continuously adapts its force, eliminating catching and enabling smooth adjustment while maintaining reliable holding at any position.

AI summary
A headphone includes an outer arc-shaped headband including two strip-shaped guide portion respectively provided at both ends of the headband. The headphone further includes two speakers respectively connected to ends of the two guide portions. The headphone further includes an inner arc-shaped head pad including two sliders respectively provided at both ends of the head pad. Each slider includes an insertion hole through which the guide portion is inserted, a wall surface along which the guide portion slides, and a pressing portion that presses the guide portion toward the wall surface.
