1st‑Gen Tech — Honeycomb Microporous Crystal Filter
99.9%‑purity Crystal Raw Material
Foundation of honeycomb mesh structure
Over 100,000 precision straight‑through holes fabricated within a tiny 2.8 mm area.
Semiconductor Chip Manufacturing Process
Micrometer Straight‑through Hole Precision Tech
Breaking machining limits, hole‑diameter precision controlled at 8‑9 μm for accurate micron‑scale filtering.
Noise‑Reduction Breakthrough Tech
Honeycomb Microporous Crystal Filter
Integrates thin negative‑stiffness structure, superior thin‑wall aspect ratio and high Young’s modulus for efficient acoustic‑energy conversion.
2nd‑Gen Tech — Helmholtz Multi‑Unit Acoustic Attenuation Filter
Semantic Blur Engine
Herschel‑Quincke Interference Technology
Generates destructive interference via acoustic path difference, precisely weakening the core human‑voice semantic band (2‑5 kHz), preventing automatic brain parsing and reducing cognitive distraction.
Transient Absorption Engine
Helmholtz Resonance Technology
Porous‑ceramic resonant cavities convert sharp noise into heat with millisecond‑level response; switchable frequencies adapt to diverse scenarios.
Three‑Stage Physical Filter System
Three‑Stage Filtering Technology
Synergistically composed of nano‑micro membranes, interference units and resonant arrays. It only processes interfering frequencies while fully preserving ambient safety signals.
