Electromagnetic Chordophone Sustaining String Vibrations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chordophone instruments, such as guitars and harpsichords, struggle to produce sustained sounds that do not quickly diminish in volume after initiation.
Innovation Solution
The development of an electromagnetic multi-function multi-purpose chordophone instrument with a rigid frame, where strings vibrate freely in the open air space between the solid body and tuning machine elements, and are amplified using electromagnetic transducers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional chordophone instruments (guitars, harpsichords) are used, then the instrument structure is simple and easy to manufacture, but the sound volume diminishes quickly after initiation and cannot produce sustained sound
Solution Approach 1:
The patent combines acoustic resonance chambers with electromagnetic transducer systems into a unified instrument structure. The electromagnetic transducers are integrated within the instrument body, merging electrical amplification with acoustic resonance to achieve sustained sound without requiring complex external amplification equipment.
Solution Approach 2:
Electromagnetic transducers serve as intermediaries between the vibrating strings and the air, converting mechanical string vibrations into electromagnetic signals that can be amplified and sustained. This intermediary mechanism allows the strings to vibrate freely while maintaining sound output over extended periods.
2Measurement precision
If strings are constrained by frets or fretboards to enable precise note production, then note accuracy is improved, but the strings cannot vibrate freely and sound sustain is reduced
Solution Approach 1:
The instrument divides the string vibration space into segmented resonance chambers, each equipped with electromagnetic transducers. This segmentation allows strings to vibrate freely in dedicated spaces while maintaining precise note identification through the resonance characteristics of each chamber.
Solution Approach 2:
The patent replaces the traditional mechanical fret system with an electromagnetic detection system. Instead of using physical frets to define notes, electromagnetic transducers detect string vibrations at specific positions, allowing strings to vibrate freely without mechanical constraints while maintaining note accuracy.
3Duration of action of moving object
If artificial reverberation is used to extend sound duration, then sound sustain is improved, but the natural vibration period of strings is altered and musical expression is compromised
Solution Approach 1:
The instrument uses passive electromagnetic transducers that detect and amplify string vibrations without actively modifying the vibration characteristics. The system serves itself by converting mechanical energy to electromagnetic signals and back, maintaining the natural vibration period and timbre of the strings while extending sound duration.
Solution Approach 2:
The electromagnetic transducer system serves multiple functions: it detects string vibrations, amplifies the signal, and sustains the sound without requiring separate artificial reverberation systems. This multi-functionality allows the instrument to maintain natural vibration characteristics while achieving extended sound duration.

AI summary
An electromagnetic multi-function multi-purpose chordophone musical instrument upon which any form or style of music may be played in any position by a performer standing or seated, in a fixed location or moving throughout a performance venue. The player may initiating the vibrations of each string, any combination of strings, or all of the strings with a plectrum or the fingers of one or both hands, singly or in any combination and such vibrations will continue until their eventual natural termination unless damped and/or muted by the player using the fingers or the palm of one or both hands singly or in any combination. The shape and style of the rigid frame of the instrument is not limited by the need for frets, a fretboard, or keys.
