Acoustic Indication TRIZ Cases
- Mechanical Wristwatch Sound Mechanism With Groove Disc and Membrane
A grooved rotating element, lever amplifier, and membrane let a mechanical wristwatch reproduce music or speech with reduced movement noise.
- Watch Case Cover for Acoustic Membrane Dust Protection
An articulated cover shields the watch acoustic membrane from dirt while preserving free vibration, sound diffusion, and easy cleaning.
- Stone-Inlaid Timepiece Gong for Stronger Resonance Without Dissonance
A hard stone impact surface in a notched timepiece gong boosts resonance and sound intensity while avoiding dissonance in multi-gong striking mechanisms.
- Stone-Embedded Timepiece Gong for Richer Sound Without Dissonance
A stone set into the gong strike zone boosts resonance and low-frequency sound while avoiding dissonance in timepiece striking mechanisms.
- Watch Acoustic Membrane Side Clamping for Better Vibration Transfer
Side clamping an acoustic watch membrane improves gong vibration transfer while allowing tension adjustment for stronger sound radiation.
- Watch Gong Alloy Composition to Limit Deformation and Preserve Sound
High-modulus tungsten, tantalum, rhodium, or hafnium alloys help watch gongs resist sagging while keeping rich sound in tight case space.
