Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with multiple speakers often face challenges in achieving optimal sound distribution and minimizing sound interference between speakers, leading to suboptimal acoustic performance.
Innovation Solution
The electronic apparatus incorporates a housing with two sound-emitting components, each containing multiple sound-emitting elements with differing main sound-emitting directions. These components are strategically placed on opposite sides of the housing, with the tweeters positioned above the speakers and angled to expand sound-emitting directions, reducing interference and enhancing sound diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple speakers are arranged in conventional configurations, then the device can reproduce sound, but sound interference between speakers occurs and sound distribution is suboptimal
Solution Approach 1:
The patent transitions from conventional planar speaker arrangements to a three-dimensional configuration where tweeters are positioned above speakers and angled outward. This spatial dimensionality change creates distinct sound emission paths that reduce interference while improving overall sound distribution quality.
Solution Approach 2:
Different parts of the sound-emitting system are given different orientations and positions tailored to their specific functions. Tweeters are angled to emit high-frequency sounds forward, while speakers are positioned below to emit mid and low-frequency sounds, creating locally optimized sound emission characteristics that minimize mutual interference.
2Power
If speakers are positioned to maximize sound output, then sound volume increases, but sound interference between speakers worsens
Solution Approach 1:
The sound-emitting system is segmented into functionally distinct components (tweeters for high frequencies, speakers for mid and low frequencies) positioned at different locations and angles. This segmentation allows each component to operate at optimal parameters without causing interference to other components, maximizing overall sound output while minimizing harmful interactions.
