Earphone Blocking Member for Noise Isolation and Sound Leakage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Earphones suffer from poor listening effects and significant sound leakage due to external noise interference, requiring higher volumes to compensate, which increases sound leakage.
Innovation Solution
An earphone design incorporating a loudspeaker component with a blocking member that extends into the ear canal, vibrating to enhance air conduction and reflect sound waves, while also blocking external noise, thereby reducing the volume needed and minimizing sound leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If external noise enters the ear canal, then users need to use higher headphone volume to compensate, but this increases sound leakage
Solution Approach 1:
The blocking member acts as an intermediary element between the external environment and the ear canal. It physically blocks external noise from entering the ear canal while allowing the loudspeaker's sound to be transmitted effectively, thereby eliminating the need to increase volume to compensate for external noise and subsequently reducing sound leakage
Solution Approach 2:
The blocking member extracts or removes the harmful external noise from the ear canal environment. By taking out external noise interference, the system no longer requires higher volume compensation, which directly reduces the sound leakage problem
2Reliability
If users increase headphone volume to compensate for external noise, then listening clarity improves, but sound leakage increases
Solution Approach 1:
The blocking member serves as a mediator that improves listening clarity by blocking external noise interference. This allows users to listen at lower volumes while maintaining clarity, thereby reducing sound leakage without sacrificing listening quality
3Object-affected harmful factors
If blocking member extends into ear canal, then noise isolation improves, but device complexity increases
Solution Approach 1:
The blocking member is designed as a separate, independent component that can be easily attached to or integrated with the earphone housing. This segmentation allows for simple manufacturing and assembly while achieving effective noise isolation, avoiding excessive structural complexity
Solution Approach 2:
Instead of making the earphone structure more complex to achieve noise isolation, the invention inverts the approach by adding a simple blocking member that extends into the ear canal. This inverted approach achieves noise isolation through a different mechanism (physical blocking rather than complex acoustic engineering), reducing overall device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves sound quality and reduces sound leakage by increasing the perceived volume through enhanced air conduction and effective noise isolation, allowing users to hear content clearly at lower volumes.
Implementation Method 1
the at least one blocking member may vibrate with a body of the earphone, causing the surrounding air to vibrate and transmit sound to the eardrum
Implementation Method 2
more sound waves generated by the loudspeaker component may be reflected to the ear canal by the at least one blocking member
Implementation Method 3
The at least one blocking member also blocks external noise from being transmitted to the ear canal

AI summary
The present disclosure discloses an earphone. The earphone includes a loudspeaker component and at least one blocking member, the at least one blocking member including a first blocking member, the first blocking member being provided on one side of the loudspeaker component, wherein, in a wearing state, at least a portion of the first blocking member extends in an extension direction from the loudspeaker component to an ear canal of a user. In the above manner, the earphone provided in the present disclosure can increase a volume heard by the user's ear, so that the user can hear the content with a smaller volume and also the sound leakage can be reduced, thereby improving the user's listening effect.
