Percussion Musical Instruments TRIZ Cases
- Handheld Noisemaker With Interchangeable Core Components
A handheld noisemaker uses interchangeable core components to produce distinct sounds.
- Zirconium-Modified Cu-Sn Bronze Alloy Grain Refinement
Zirconium addition micronizes crystal grains in copper-tin bronze alloys, resolving brittleness caused by coarse microstructures at high tin concentrations.
- Drum Membrane Insert for Frequency Control and Ringing Reduction
A dampening insert lowers the fundamental resonant frequency while suppressing dissonant overtones.
- Drum Stand Collar Mechanism for Independent Leg Height Adjustment
Sliding collars adjust leg heights independently, solving complexity issues in step placement.
- Non-Contact Sound Absorbing Apparatus for Musical Instruments
A non-contacting sound absorbing apparatus attenuates acoustic energy near musical instruments without physical interaction.
- Cajon Widening Bodies for Ergonomic Playing Surface
Segmented widening bodies expand the lateral width of the instrument to improve playing comfort without increasing vertical height or structural complexity.
- Cajón Playing Device Foot-Operated Mallet Assembly
A cajoon playing device integrates a foot-operated pedal lever with a rotating shaft and mallet assembly for direct striking.
- Pedal Apparatus Pivot Shaft Alignment via Segmented Support
Separate support members enable fine adjustment of pivot shaft positions, preventing wobbling and misalignment in percussion instrument pedals.
- Marching Drum Dampener Hinge Mechanism
Friction-based hinge dampeners absorb rotational energy to eliminate harsh stop forces on the player.
- Cymbal Damping Tool With Reticulated Membrane
A cymbal damping tool uses a reticulated membrane to attenuate vibrations while preserving original sound quality.
- Vibraphone Fan Drive Magnetic Coupling Vibration Isolation
Magnetic coupling transmits rotational power to vibrato fans while isolating motor vibrations from resonators.
- Modular Drum with Magnetic Shell Assembly
Segmented drum shells joined by magnets resolve transport volume issues while maintaining structural stability.
- Bilateral Drum Pedal Split Shaft Ergonomics
Segmented pedals with adjustable concentric chain drives resolve the trade-off between wide foot spacing and tight beater positioning.
- Elastic Pin Support for Xylophone Bars
Conical contact points reduce vibration disturbance and improve sound quality.
- Snare Drum Strainer Cam Mechanism for Low-Force Operation
A snare drum strainer uses a cam mechanism to convert lever rotation into linear wire tension.
- Segmented Percussive Instrument with Tunable Hollow Chamber
A segmented percussive instrument uses a hollow chamber and plug member to define a resonant volume for sound production.
- Tuned Steel Hand Pan Tongue Drum Sympathetic Resonance
Integrating cut tongues with tone fields in a steel dome creates sympathetic vibration that improves harmonic tones and extends duration.
