Motorized Loudspeaker Positioning and Acoustic Filter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional loudspeakers in enclosed spaces suffer from poor performance due to difficult radiation properties, and existing solutions fail to dynamically adapt sound emission to the listener's position, resulting in suboptimal listening experiences regardless of the acoustical properties of the room.
Innovation Solution
A speaker system with rotatable and tiltable speaker units, controlled by motorized means using polar coordinates, and adjustable filters based on user input or automatic detection of the listener's position, to optimize sound emission and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If loudspeaker units are fixed in position, then the device structure is simple, but the acoustical performance is poor and cannot adapt to different listener positions
Solution Approach 1:
The loudspeaker system employs motorized means to enable dynamic adjustment of speaker unit positions and orientations. The first and second loudspeaker units can be independently positioned and oriented towards the listener, allowing the system to adapt to different listening positions and preferences, transforming a static system into a dynamic one that responds to user needs
Solution Approach 2:
The system divides the loudspeaker assembly into separate, independently controllable units. Each loudspeaker unit can be individually positioned and oriented, allowing selective adjustment of different speaker components to optimize sound delivery to the listener, rather than moving the entire assembly as a single unit
2Reliability
If traditional fixed loudspeakers are used, then the device complexity is low, but the sound emission and acoustical performance are poor in enclosed spaces
Solution Approach 1:
The system dynamically changes the spatial parameters of the loudspeaker units by adjusting their positions and orientations using motorized means. This allows optimization of sound emission patterns and acoustical performance for different listening conditions, transforming fixed parameters into adjustable ones to achieve better sound quality
Solution Approach 2:
The system incorporates detection means to automatically detect the listener's position and uses this information to control the positioning and orientation of the loudspeaker units. This feedback loop ensures that the acoustical performance is continuously optimized based on the actual listening position, maintaining high reliability across different usage scenarios

AI summary
The invention relates to a method and a system for optimizing the performance of a loudspeaker system as perceived by user.The physical part of the speaker system is adjustable which enables the speaker units to be placed in positions that imply maximal acoustical performance. This is obtained by combined means to: 1) bring the speaker in a specified position and 2) apply accordingly position dependant individual acoustical filters inserted in the signal path to each individual speaker.
