Over-Ear Headphone Clamping Mechanism With Button-Locked Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional over-ear headphones face issues with clamping force adjustment mechanisms that are prone to losing adjustment pads or require time-consuming screw tightening, leading to discomfort and sound leakage due to inadequate fit.
Innovation Solution
An over-ear headphone design utilizing buttons to release pins for adjusting clamping force, allowing quick and easy adjustment by engaging or disengaging the pin with the pivot base via button press, and fixing the pivot angle when the button is released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adjustment pads or screws are used for clamping force adjustment, then the clamping force can be adjusted, but the adjustment pads may be lost during operation or the screw tightening process is time-consuming and strenuous
Solution Approach 1:
The patent extracts the adjustment pad from the system and replaces it with a pin-button mechanism. The pin is telescopically disposed through the adjusting component and can be engaged or disengaged from the pivot base by pressing the button, eliminating the need for separate adjustment pads that can be lost.
Solution Approach 2:
The button mechanism provides self-service functionality where pressing the button automatically pushes the pin out of the hole structure to release the clamping force, and releasing the button allows the pin to return to engage and fix the pivot angle, eliminating the need for external tools or complex operations.

Solution Approach 2:
The patent replaces the traditional screw tightening mechanism with a button-actuated pin release mechanism. The button is pressably disposed at the first side of the pivot base with a protrusion that enters the hole structure to push the pin out, substituting complex mechanical screw operations with a simple pressing action.

AI summary
An over-ear headphone(10) includes a headband(12), two earmuffs(14), and two clamping-force adjusting mechanism(16) connecting the earmuffs(14) to the headband(12). Each clamping-force adjusting mechanism(16) includes a pivot base(18), an adjusting component(20), a pin(22), and a button(24). The pivot base(18) is connected to the headband(12) and has a hole structure(30) at a first side. The adjusting component(20) is pivoted to the pivot base(18) and connected to the earmuff(14). The pin(22) is telescopically disposed through the adjusting component(20). The button(24) is pressably disposed at the first side. When the button(24) is pressed, a protrusion(42) of the button(24) enters the hole structure(30) to push the pin(22) out of the hole structure(30), for allowing the adjusting component(20) to rotate to adjust a clamping force of the earmuff(14) upon a user's head. When the button(24) is released, the pin(22) returns to be engaged with the hole structure(30) for fixing a pivot angle of the adjusting component(20).
