Solution Overview

Problem

Wireless earphones with built-in microphones often suffer from poor voice pickup quality due to the microphone's distance from the user's mouth, leading to increased ambient noise collection.

Innovation Solution

An earphone design featuring a movable component with a third built-in microphone that can be positioned closer to the user's mouth, switching between stored and sticking out positions to activate or deactivate other microphones, allowing for improved voice pickup and noise suppression by adjusting the microphone configuration based on the movable component's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the built-in microphone is positioned away from the user's mouth, then the earphone structure is simple and compact, but the voice pickup quality deteriorates and ambient noise increases

Engineering Contradiction:
Improveearphone structureVSAvoidvoice pickup quality
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent implements a movable component that can switch between a stored position (microphone away from mouth) and a sticking out position (microphone close to mouth). This dynamic positioning allows the system to adapt to different usage scenarios, improving voice pickup quality when needed while maintaining a compact structure when the microphone is retracted.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent divides the microphone system into multiple segments: a first built-in microphone, a second built-in microphone, and a third built-in microphone on the movable component. This segmentation allows different microphones to be activated based on the movable component's position, optimizing voice pickup while managing structural complexity.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the movable component is positioned close to the user's mouth, then voice pickup quality improves, but the risk of misplacement or loss increases

Engineering Contradiction:
Improvevoice pickup qualityVSAvoidmicrophone positioning reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The movable component is designed to be dynamically adjustable between stored and sticking out positions, allowing the user to control when the microphone is close to the mouth. This reduces the risk of permanent misplacement while enabling high-quality voice pickup when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses the position of the movable component to automatically control which microphones are activated. When the movable component is in the sticking out position, the third built-in microphone is activated; when stored, the first and second microphones are activated. This feedback mechanism ensures reliable operation based on the actual microphone position.

Inventive Principle:
Principle #23Feedback

AI summary

An earphone includes a main body and a movable component. The main body accommodates a first built-in microphone and a second built-in microphone therein. The movable component accommodates a third built-in microphone therein. The movable component is movably disposed on the main body and has a stored position and a sticking out position. When the movable component is in the stored position, the main body activates the first built-in microphone and the second built-in microphone and deactivates the third built-in microphone. When the movable component is in the at least one sticking out position, the third built-in microphone is located relatively away from the main body, and the main body deactivates one of the first built-in microphone and the second built-in microphone and activates the third built-in microphone.
