Solution Overview
Problem
Existing portable sound systems for musicians lack mobility and versatility, particularly in providing wireless, hands-free microphone options and high-quality audio amplification with reverb and delay effects, while being battery-powered and compact.
Innovation Solution
A portable, battery-powered speaker system with a built-in receiver and wireless transmitter microphone, featuring a clip-on or headset apparatus for instrumentalists and vocalists, offering hands-free mobility and enhanced audio signal processing through digital reverb/delay and equalizer controls, housed in a compact design with a bag-pack or shoulder strap for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a portable speaker system is designed to be compact and battery-powered for mobility, then portability and ease of movement are improved, but audio quality and power output tend to deteriorate
Solution Approach 1:
The patent combines multiple functions into a single integrated portable speaker system: wireless microphone reception, digital reverb/delay effects processing, equalizer controls, and high-quality audio amplification are all merged into one compact battery-powered device. This allows the system to provide professional audio capabilities in a portable form factor that weighs only 13 pounds.
Solution Approach 2:
The patent employs digital signal processing to dynamically adjust audio parameters including reverb time, delay time, equalizer frequency response, and volume levels. These parameter changes enable high-quality audio output from a compact system by optimizing the electrical and acoustic characteristics of the audio chain.
2Ease of operation
If wireless transmitter microphones are added for hands-free performance, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The portable speaker system serves multiple functions: it acts as a wireless microphone receiver, an audio amplifier, a digital effects processor (reverb and delay), and an equalizer. This multi-functionality reduces the need for separate equipment while providing comprehensive hands-free performance capabilities.
Solution Approach 2:
The wireless microphone reception system is integrated into the speaker system, combining wireless communication capabilities with audio processing and amplification in a single device. This merging reduces overall system complexity compared to using separate wireless microphone and speaker systems.
3Reliability
If digital reverb and delay effects are included for audio enhancement, then audio quality is improved, but device complexity and processing requirements increase
Solution Approach 1:
The digital reverb and delay effects processing are integrated into the portable speaker system's audio chain, combining multiple audio processing functions within a single compact device. This allows high-quality audio enhancement without requiring separate effects processors.
4Volume of moving object
If the speaker is designed to be compact for portability, then ease of movement is improved, but the size of audio drivers and tweeters is limited
Solution Approach 1:
The patent employs digital signal processing and equalizer controls to optimize the electrical and acoustic parameters of the audio drivers and tweeters. By adjusting frequency response, gain, and signal processing parameters, the system maximizes the output power and audio quality of the compact drivers.
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
