TWS Audio Waterproof Acoustic Vent Membrane
TWS Acoustic Vent Membrane for Earbuds
Our TWS acoustic vent membrane is specially designed for true wireless stereo earbuds, Bluetooth headsets and miniature audio devices. It provides waterproof protection while maintaining clear and natural sound transmission.
Why TWS Devices Need Acoustic Vent Membranes
Modern TWS earbuds are fully sealed electronic devices. Without proper ventilation, pressure imbalance, moisture and condensation can damage microphones and speakers, leading to poor sound quality and device failure. Our ePTFE acoustic membrane solves these problems effectively.
Core Advantages
- Ultra-low acoustic loss (≤1dB) for clear and natural sound transmission
- IP67/IP68 waterproof and sweatproof protection for daily use
- Microporous ePTFE structure ensures stable acoustic performance
- Prevents dust and moisture entering microphone and speaker units
- Custom micro die-cut shapes for compact earbud structures
Main Applications
- True wireless stereo (TWS) earbuds
- Bluetooth wireless earphones
