Wireless Audio Mixer for Venue Sound Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large venues face challenges in providing consistent high-quality audio to all attendees due to sound delays and interference between multiple speaker systems, making it difficult to balance sound levels for individual preferences.
Innovation Solution
An audio mixer system with a receiver and controller that adjusts relative volumes and combines audio channels using wireless communication, allowing users to set preferences via a separate interface device, and synchronizes audio signals to minimize delays and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple speaker systems are distributed around the venue to provide consistent sound quality, then sound coverage is improved, but sound delays and interference between speakers worsen
Solution Approach 1:
The patent replaces the traditional mechanical acoustic system (multiple loudspeakers reproducing sound) with an electronic system. The audio mixer receives multiple audio channels, processes them electronically, and transmits the mixed signal wirelessly to headphones worn by individual audience members. This substitution eliminates sound delays and interference between speakers while maintaining sound quality consistency across the venue.
Solution Approach 2:
The patent introduces an audio mixer as an intermediary device between the stage audio sources and the audience. The mixer consolidates multiple audio channels (vocals, instruments, etc.) into a single processed signal that is then distributed to all audience members via wireless transmission to headphones. This intermediary approach eliminates the need for multiple distributed speaker systems and their associated problems.
2Device complexity
If a single mix is projected throughout the venue, then system complexity is reduced, but individual audience preferences cannot be accommodated
Solution Approach 1:
The patent applies local quality by providing customized audio mixes to individual audience members through their personal headphones. Each audience member can adjust their own audio mix preferences (e.g., vocals vs. instruments volume balance) independently, while the overall system remains relatively simple. The audio mixer processes multiple channels and allows individual customization without requiring complex distributed speaker systems.
3Adaptability or versatility
If audio channels are processed individually to accommodate preferences, then adaptability is improved, but device complexity increases
Solution Approach 1:
The audio mixer is designed as a universal device that handles multiple audio channels (vocals, guitars, drums, etc.) simultaneously. It provides a standardized interface for receiving audio content settings from the user interface device and applies these settings across all channels. This multi-functional approach allows individual customization without requiring separate complex processing for each channel.
