Handheld Wireless Audio Mixing Console
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio mixers are bulky, require external power, and are not capable of receiving, processing, and transmitting multiple wireless audio signals, making them unsuitable for portable use in settings like gatherings and travel.
Innovation Solution
A portable, hand-held, battery-powered, wireless stereo multi-channel audio mixing console that can receive and mix multiple independent stereo audio signals from devices like cellular phones and iPads, adjust their frequencies and volumes, and transmit the mixed signals to speakers via Bluetooth, allowing for easy handling and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mixers are used, then audio mixing function is provided, but the device becomes bulky and non-portable
Solution Approach 1:
The patent combines multiple audio mixing functions into a single handheld device that integrates wireless reception, audio processing, and transmission capabilities. The mixing console merges the functions of receiving multiple wireless audio signals, processing them independently, and transmitting mixed outputs, all within one compact unit that can be held in a user's hand.
Solution Approach 2:
The device performs multiple functions simultaneously: it receives wireless audio signals from multiple sources, processes and mixes them, and transmits the mixed signal to speakers. This multi-functional integration eliminates the need for separate equipment for each function, achieving portability while maintaining full audio mixing capability.
2Ease of operation
If conventional mixers are used, then audio processing is provided, but external power is required
Solution Approach 1:
The mixing console is designed to be self-powered through an internal battery, eliminating the need for external power sources. The device independently manages its own power requirements, allowing it to function portably without being tethered to power outlets or requiring external power adapters.
3Adaptability or versatility
If conventional mixers are used, then audio mixing is provided, but wireless signal reception is not supported
Solution Approach 1:
The device integrates wireless reception capability directly into the mixing console, allowing it to receive multiple wireless audio signals from different sources simultaneously. This universal design combines traditional audio mixing with modern wireless technology, enabling the device to adapt to various usage scenarios without requiring separate wireless receivers.
4Adaptability or versatility
If multiple wireless audio signals are received, then channel versatility is improved, but device complexity increases
Solution Approach 1:
The device segments the audio processing into independent channels, where each received wireless audio signal is processed separately through its own frequency tuning and volume control. This segmentation allows multiple channels to be handled independently, maintaining versatility while managing complexity through modular processing architecture.
Solution Approach 2:
Each audio channel receives localized processing with independent frequency tuning and volume control specific to that channel. This local quality approach allows each channel to be optimized independently, enabling multi-channel versatility without requiring complex global processing that would increase overall device complexity.
Data Source
AI summary
A battery powered, portable multi-channel audio mixing console is disclosed. The mixing console is configured to be easily held in a user's hand like a remote control. The console is configured to wirelessly receive, via separate channels, two or more independent stereo input audio signals from separate audio sources such as cellular phones, iPads, iPods, or other computing or media player devices, independently equalize the frequencies of those input signals, independently adjust the volume of those input signals, and then mix those audio signals into a combined output signal. The console further includes user controls that can vary the relative magnitude of the first and second input signals in the combined output signal. The console is further adapted to transmit the combined output signal to one or more speakers via independent channels.
