Acoustic Module Sound Channel Alignment for Microphone Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated acoustic modules in electronic products often fail to align the sound emission and receiving positions correctly, leading to adverse impacts on acoustic performance due to misalignment between the sound emission and receiving holes.
Innovation Solution
The acoustic module design includes a module housing with a through hole in the side wall, a fixing member with a sound channel, and a microphone positioned to align with the sound receiving hole, ensuring proper communication and alignment with the sound receiving opening in the electronic product housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the acoustic module integrates both sound emission and receiving functions, then the device functionality is improved, but the positional alignment between sound emission and receiving holes becomes difficult to achieve
Solution Approach 1:
The acoustic module is divided into separate functional components: a sound emission component with a sound emission hole and a microphone component with a sound receiving hole. These components are positioned at different locations within the module housing, allowing each component to be optimized for its specific function while maintaining overall positional alignment through modular design
Solution Approach 2:
A sound transmission channel is introduced as an intermediary structure that connects the sound emission hole and the sound receiving hole. This channel serves as a mediator that enables acoustic signal transmission between the two components while maintaining their spatial separation and functional independence
2Adaptability or versatility
If the electronic product housing is provided with both sound emission and receiving holes, then the acoustic module functionality is improved, but the component arrangement complexity increases
Solution Approach 1:
The sound emission component and microphone component are integrated into a single acoustic module assembly. This merging of components into one unified module simplifies the overall component arrangement in the electronic product housing while maintaining both sound emission and receiving functions
