Removable Audio Capture Apparatus for Spatial Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio capture devices, such as mobile electronic devices, face limitations in capturing high-quality spatial audio signals due to their spatial audio recording capabilities, which can be improved by enhancing the positioning and processing of audio signals relative to the device.
Innovation Solution
An apparatus with processing circuitry and memory circuitry, configured to establish a wireless connection with an electronic device, capture audio signals, and create enhanced audio signals such as spatial, beamformed, or noise-cancelled signals, by determining its position relative to the device and processing the signals before transmission, and can be removably attached as a cover with microphones, transceivers, and a power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio signals are captured by microphones distributed in different locations, then spatial audio recording capabilities are improved, but device complexity increases
Solution Approach 1:
The audio capture system is segmented into multiple distributed microphones located at different positions on the electronic device. Each microphone captures audio signals from its specific location, and the processing circuitry combines these segmented signals to create enhanced spatial audio recordings with improved directional properties.
Solution Approach 2:
The system transitions from single-point audio capture to multi-dimensional spatial audio capture by distributing microphones across different locations on the device. This dimensional expansion enables the capture of spatial characteristics and directional properties of sounds, creating immersive audio experiences.
2Adaptability or versatility
If the apparatus is made removably attachable to the electronic device, then adaptability is improved, but reliability deteriorates
Solution Approach 1:
The apparatus transitions from a static integrated configuration to a dynamic removable configuration. The cover can be attached to or detached from the electronic device based on user needs, enabling flexible adaptation to different usage scenarios while maintaining reliable audio capture functionality in both states through wireless or wired connections.
