Acoustic Conduit Frame Layout for Speaker-Display Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently connecting speakers and audio holes within the device while maintaining structural integrity and acoustic performance, particularly when integrating displays and electronic components.
Innovation Solution
The electronic device incorporates a frame with separate frame parts that house a speaker and an audio hole, featuring an acoustic duct that separates the speaker space from the display components, ensuring clear sound transmission without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the acoustic duct is formed as an empty space inside the electronic device to connect the speaker and audio hole, then the acoustic performance is improved, but the space for displaying the third portion of the display is reduced
Solution Approach 1:
The frame is divided into multiple frame parts that create separate spaces: an acoustic duct space for sound transmission and a display space for the third portion of the display. This segmentation allows both the acoustic duct and display to occupy distinct volumes within the electronic device, resolving the space conflict between audio and display functions.
Solution Approach 2:
The acoustic duct extends in a direction substantially perpendicular to the display surface, utilizing the vertical dimension rather than competing for horizontal display space. This dimensional separation allows the acoustic duct to pass through the frame structure without encroaching on the display area, maintaining both acoustic performance and display visibility.
2Reliability
If the acoustic duct passes through the frame structure, then the sound transmission path is established, but the structural integrity of the frame is compromised
Solution Approach 1:
The frame is segmented into multiple frame parts that collectively form the acoustic duct pathway. Each frame part maintains structural strength while the combination of parts creates the continuous acoustic transmission path from the speaker to the audio hole, balancing sound transmission requirements with structural integrity.
3Reliability
If the acoustic duct is separated from the display components by frame parts, then acoustic interference is reduced, but the device complexity increases
Solution Approach 1:
The frame parts serve multiple functions simultaneously: they provide structural support for the display, create the acoustic duct pathway, and act as separation barriers between the acoustic and display spaces. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while achieving acoustic isolation.
