Acoustic Box Partitioning for Speaker Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple speakers are disposed inside an acoustic box, interference and energy attenuation occur at certain frequency bands, compromising sound quality.
Innovation Solution
The use of partitions within the acoustic box to separate the speakers into semi-connected sub-spaces, preventing interference between their vibration airflow and maintaining energy distribution across frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If more than two speakers are disposed inside the acoustic box to produce better sound quality, then the sound quality is improved, but interference phenomenon and energy attenuation occur at certain frequency bands
Solution Approach 1:
The acoustic box is segmented into multiple independent sub-spaces using partitions. Each speaker is disposed in a separate sub-space, which divides the original acoustic space into isolated sections. This segmentation prevents the vibration airflow from different speakers from interfering with each other, thereby eliminating interference phenomena while maintaining improved sound quality.
2Illumination intensity
If more than two speakers are disposed inside the acoustic box to produce better sound quality, then the sound quality is improved, but energy attenuation phenomenon occurs at some frequency bands
Solution Approach 1:
By segmenting the acoustic box into separate sub-spaces with partitions, each speaker operates in an independent acoustic environment. This prevents energy from one speaker from being dissipated or attenuated by the presence of other speakers, thereby maintaining energy distribution across frequency bands and preventing energy attenuation phenomena.
3Object-generated harmful factors
If partitions are disposed to separate speakers into semi-connected sub-spaces to prevent interference, then interference is prevented, but the device complexity increases
Solution Approach 1:
Partitions are introduced as intermediary structures between speakers to prevent direct interaction of their vibration airflow. These partitions act as mediators that separate the acoustic fields of different speakers while allowing the overall acoustic box to remain a unified structure. The partitions effectively eliminate speaker interference without requiring complete isolation, thus managing complexity at an acceptable level.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively prevents energy attenuation at specific frequency bands, ensuring improved sound quality by minimizing speaker interference and maintaining consistent energy distribution.
Implementation Method 1
the partition divides the acoustic box into two semi-connected sub-spaces... the vibration airflow of the first speaker and the vibration airflow of the second speaker do not interfere with each other
