Acoustic Vent & Waterproof Acoustic Membrane | Shieldzone

Shieldzone acoustic vents and ePTFE acoustic membranes provide waterproof sound transmission for microphone and speaker openings, with acoustic evaluation and custom die-cut formats.

Acoustic vents and waterproof acoustic membranes

Shieldzone acoustic vents use ePTFE acoustic membrane technology to protect exposed sound paths from liquid water, sweat and particles while allowing sound to pass through microphone and speaker openings.

Selection depends on the required frequency range, insertion-loss target, active area, adhesive opening, device sound channel, environmental exposure and assembly process. Final performance must be verified in the complete acoustic structure.

An acoustic membrane is the functional sound-transmissive layer. Acoustic vent commonly refers to the converted membrane component supplied with adhesive, liner or support structure for installation in a device.

Engineering FAQ

A waterproof acoustic membrane is the functional sound-transmitting layer. An acoustic vent often means the assembly-ready part with adhesive and support. For microphones and speakers, compare the complete sound path rather than treating acoustic vent and pressure-equalization vent as interchangeable parts.

What is an ePTFE acoustic membrane?

An ePTFE acoustic membrane is a microporous component placed over a microphone or speaker opening to help block water and particles while allowing sound to pass.
