Waterproof Acoustic Membrane

The Waterproof Acoustic Membrane is an advanced protective solution engineered to deliver exceptional sound transparency while providing robust defense against water, dust, and environmental contaminants. This acoustic Waterproof Membrane is specifically designed for demanding applications where both audio performance and environmental sealing are critical.

Manufactured using high-quality PTFE and ePTFE materials, our Waterproof Acoustic Membrane ePTFE solution achieves an optimal balance between acoustic clarity, waterproof protection, and long-term durability. As a professional acoustic membrane manufacturer, acoustic membrane supplier, and acoustic membrane factory, we provide reliable and customizable solutions for global customers across electronics, automotive, medical, and industrial markets.

Waterproof Acoustic Membrane – Key Features

1. Outstanding Waterproof Protection

The waterproof acoustic membrane supports IP54, IP67, and IP68 protection levels, effectively preventing water, dust, humidity, and contaminants from entering device enclosures. It is widely used as a waterproof sound membrane, acoustic vent membrane, or acoustic vent for sealed electronic housings.

2. High Acoustic Transparency

Engineered for precise audio transmission, this sound transmission membrane ensures minimal sound loss while maintaining natural sound quality. As a high-performance sound permeable membrane, it is ideal for microphones, speakers, voice sensors, and audio modules that demand stable and distortion-free acoustic performance.

3. Exceptional Durability & Environmental Resistance

The ePTFE acoustic membrane offers excellent resistance to chemicals, UV exposure, and extreme temperatures. This makes the waterproof acoustic membrane ePTFE suitable for harsh outdoor, automotive, and industrial environments.

4. Thin & Lightweight Structure

With an ultra-thin design (as low as 0.015 mm), the acoustic membrane integrates easily into compact and lightweight devices without affecting acoustic performance or device aesthetics.

5. Customizable & Versatile Options

As a professional custom waterproof acoustic membrane provider, we support various shapes, sizes, colors, thicknesses, and adhesive solutions. OEM acoustic membrane and ODM services are available to meet different application requirements.

FAQ – Waterproof Acoustic Membrane

1. What is a Waterproof Acoustic Membrane?

A waterproof acoustic membrane is a microporous film that allows sound to pass through while blocking water, dust, and contaminants. It is commonly used in microphones, speakers, sensors, and outdoor electronics.

2. How does an Acoustic Waterproof Membrane work?

The membrane uses microporous PTFE or ePTFE structures that allow air and sound waves to pass while preventing liquid water ingress.

3. PTFE vs ePTFE Acoustic Membrane – What’s the difference?

• PTFE Acoustic Membrane: Basic hydrophobic protection

• ePTFE Acoustic Membrane: Higher breathability, lower sound loss, and better waterproof venting performance

4. What IP ratings are available?

We offer IP54, IP67, and IP68 waterproof sound membranes for different application environments.

5. Will waterproofing affect sound quality?

No. Our sound transmission membrane is designed to maintain high acoustic transparency with minimal sound loss.

6. Which industries use Acoustic Membranes?

Consumer electronics, automotive systems, outdoor communication devices, industrial sensors, and medical equipment.
