Speaker Waterproof Sound Membrane
 | Headline: SpeakerWaterproof Sound MembraneType: Adhesive Die-cut Acoustic Film |
Speakers and earphone microphones are easily corroded by sweat and rain. Ordinary dust nets can’t block water, which causes distorted sound and short circuits.
Mimoyin ePTFE acoustic film reaches IP67 waterproof grade, delivering clear sound without muffling. The thin adhesive film supports customized die-cut shapes.
It is sweat-proof, temperature-resistant and anti-aging, and complies with RoHS environmental standards.
Widely applied to Bluetooth earphones, smart watches, car speakers and camera microphones. Custom specs and fast sampling are available.
We own dust-free workshop and complete testing machines with stable quality. Feel free to contact us for samples.
