Rotatable Stick Microphone Structure for Flexible Earphones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current earphones suffer from poor structural flexibility, particularly in the stick microphone component, which limits the microphone's ability to capture sound effectively.
Innovation Solution
The earphone design includes a rotatable stick microphone component with a stick assembly and a microphone assembly, featuring an elastic sheet and a pivot mechanism, allowing the microphone to position itself optimally for sound pickup and rotate relative to the speaker component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stick microphone component uses a rigid structure, then the structural stability is improved, but the structural flexibility deteriorates
Solution Approach 1:
The stick assembly is designed with a rotatable connection to the speaker component, allowing it to rotate about a preset axis. This dynamic structure enables the stick microphone component to adjust its position and orientation, improving structural flexibility while maintaining stability through controlled rotation mechanisms.
Solution Approach 2:
The stick microphone component is divided into separate modules: the stick assembly and the microphone assembly. The stick assembly includes the elastic sheet and elastic covering body, while the microphone assembly is fixedly connected to the stick assembly. This segmentation allows independent optimization of each module's properties.
2Manufacturing precision
If the stick microphone component uses a fixed position, then the manufacturing precision is improved, but the sound capture capability deteriorates
Solution Approach 1:
The stick assembly can rotate about a preset axis relative to the speaker component, allowing the microphone assembly to dynamically adjust its position. This rotation capability enables the microphone to capture sound from different directions and positions, improving sound capture capability while maintaining precise rotational control.
Solution Approach 2:
The elastic sheet provides elastic support to the stick assembly, enabling it to automatically return to its original position after rotation. This self-service mechanism allows the stick microphone component to maintain its positioning precision while providing the flexibility to adjust for optimal sound capture.

AI summary
Provides an earphone including a wearing component, a speaker component, and a stick microphone component. The wearing component is connected to the speaker component, and the stick microphone component is rotatably disposed on the speaker component around a preset axis. The stick microphone component includes a stick assembly and a microphone assembly. The microphone assembly is fixedly connected to the stick assembly. The stick assembly is configured to position the microphone assembly in a sound pickup area corresponding to a mouth of a user when the earphone is in a wearing state. The stick assembly includes an elastic sheet and an elastic covering body covering the elastic sheet, the elastic sheet has a thickness direction and a width direction perpendicular to each other, the elastic sheet includes a smaller size in the thickness direction than in the width direction. The thickness direction is set toward or away from a face of the user in the wearing state. By the above, it is possible to make the structure of the stick microphone component more flexible.
