Microphone Adapter for Wireless Audio Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless audio technologies face limitations such as interference, static, distortion, limited range, and loss of fidelity due to compression, especially in high-fidelity music transmission, and are not ideal for connecting multiple speakers to a single audio source.
Innovation Solution
A multi-chip module integrated circuit that enables wireless transmission and reception of high-definition digital audio signals over a proprietary network, eliminating the need for routers and complex setups, with features like pin-selectable logic, boot loader, and non-volatile memory for user configuration, and the ability to connect multiple receivers simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless audio technologies are used, then wireless transmission is achieved, but interference, static, distortion, and limited range occur
Solution Approach 1:
The patent replaces conventional wireless audio transmission systems with a proprietary digital wireless system that uses integrated circuits to transmit audio signals digitally rather than through traditional analog wireless methods, thereby eliminating interference and static
Solution Approach 2:
The patent changes the transmission parameters by using 24-bit HD digital audio transmission instead of conventional audio formats, which improves transmission quality and extends range while maintaining signal integrity
2Productivity
If compression is used in wireless audio transmission, then transmission efficiency is improved, but loss of fidelity occurs
Solution Approach 1:
The patent changes the audio transmission parameter from compressed formats to 24-bit HD digital audio, which maintains full audio fidelity while achieving efficient transmission through the proprietary digital wireless system
3Adaptability or versatility
If multiple speakers need to connect to a single audio source, then audio distribution capability is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal digital wireless audio system where a single audio source can simultaneously connect to multiple speakers through integrated circuits that support multi-point transmission, eliminating the need for complex routing or additional equipment
Solution Approach 2:
The patent combines the audio source and multiple speakers into a unified digital wireless network using proprietary integrated circuits, simplifying the system architecture while enabling multi-speaker connectivity
4Adaptability or versatility
If discrete components are used in wireless audio systems, then system flexibility is maintained, but RF efficiency decreases and system noise increases
Solution Approach 1:
The patent merges multiple discrete components into integrated circuits that combine RF transmission, digital audio processing, and control functions into a single unit, improving RF efficiency and reducing system noise while maintaining flexibility through programmable features

AI summary
A microphone adapter connects to and receives analog audio input from a microphone and an external music source, such as a smart phone. The microphone audio input signal and external music audio input signal are converted to digital signals and multiplexed into a digital wireless signal that may be transmitted directly to multiple speakers. The digital wireless signals are uncompressed, high definition digital audio signals transmitted in the 2.4 GHz band with a range of several hundred feet. The microphone adapter enables user to easily establish a pop-up public address system without the need for speaker cables, sound boards, mixers, and the like.
