UWB Speaker Control for Consistent Audio During User Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker devices require frequent manual adjustments in volume and sound direction due to user movement, leading to a poor listening experience.
Innovation Solution
A speaker control method that determines the relative position of the speaker device and a user-carried target device, adjusts speaker parameters such as transducer orientation and playback volume based on user position changes, using UWB technology for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual volume adjustment and sound direction rotation are used, then the speaker device can adapt to user movement, but the user experience deteriorates due to frequent manual adjustments
Solution Approach 1:
The speaker device automatically detects user position through UWB positioning technology and autonomously adjusts playback parameters including volume and sound transmission direction, eliminating the need for manual user intervention and achieving self-adaptation to user movement
Solution Approach 2:
The system continuously receives user position information from UWB positioning, processes this feedback data, and dynamically adjusts speaker parameters in real-time based on the detected position changes, creating a closed-loop adaptive system
2Measurement precision
If UWB positioning technology is implemented, then precise user position detection is achieved, but device complexity increases
Solution Approach 1:
The system employs an intermediary positioning module that handles all UWB signal processing and position calculation operations, isolating the complex positioning functionality from the main speaker control logic and enabling precise positioning without overwhelming the core system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Adaptive adjustment of speaker parameters reduces the impact of user movement on listening quality, providing a consistent audio experience without manual intervention.
Implementation Method 1
receiving a UWB signal generated from the UWB tag by the UWB base station, and determining the current relative position of the speaker device and the target device carried by the user according to the UWB signal
Implementation Method 2
Speaker devices convert electrical signals into sound signals
