Acoustic Vent Membrane

EPTFE Shark Fin Antenna Integrated Mic Protective Acoustic Vent Product Overview This EPTFE protective acoustic vent is specifically intended for the microphone element integrated into shark fin antenna assemblies for telematics, eCall, and voice commands. The antenna housing sits on the highest point of the vehicle roof, fully exposed to driving rain, snow, ice, bird droppings, and automatic car wash rollers. The vent seals the built-in microphone against direct water

EV Battery Pack Pressure Equalization Vent Bolt Waterproof Breathable Metal Threaded Product Overview The EV battery pack pressure equalization vent bolt is a critical safety component for electric vehicle battery enclosures. It combines a precision metal threaded body with a waterproof ePTFE membrane and an optional burst disc. During normal operation, it balances internal pressure caused by altitude changes and thermal cycling. In the event of a cell thermal runaway, the

EPTFE Automotive Hands Free Microphone Array Acoustic Vent Membrane Product Overview This EPTFE acoustic vent membrane is specifically designed for in-vehicle hands-free microphone arrays mounted in headliners, overhead consoles, seatbelt assemblies, or integrated into the infotainment system. It protects the MEMS microphones from humidity, spilled drinks, and interior cleaning fluids while ensuring crystal-clear voice pickup for Bluetooth calls and voice commands. The

EPTFE EV Pedestrian Warning Speaker Acoustic Vent For Safety Compliance Product Overview This EPTFE acoustic vent is dedicated to the external pedestrian warning speaker, also known as the Acoustic Vehicle Alerting System (AVAS), found on electric and hybrid vehicles. It ensures that the mandated audible warning tones are broadcast at the legal sound level while protecting the speaker from road splash, mud, snow, and road salt. The vent membrane is engineered to handle the

EPTFE Ultrasonic Parking Sensor Acoustic Vent For Vehicle Bumper Product Overview This EPTFE acoustic vent is purpose-engineered for ultrasonic parking sensors embedded in vehicle bumpers, where accurate distance measurement and environmental survival are equally critical. The membrane protects the sensor’s piezoelectric transducer from direct water spray, road salt, mud, ice, and car wash chemicals while permitting ultrasonic pulses in the 40–58 kHz range to be transmitted

EPTFE VR Headset Microphone Sweatproof Acoustic Vent Membrane Product Overview This EPTFE acoustic vent membrane is purpose-built for Virtual Reality (VR) headsets, where microphones face constant exposure to sweat, heat, and condensation during physically active gaming and training sessions. The membrane forms an impenetrable barrier against perspiration droplets while allowing the microphone to capture the user's voice commands, in-game chat, and breath with full clarity.

EPTFE Drone Microphone Acoustic Vent For Noise Reduction And Protection Product Overview This EPTFE acoustic vent is specifically engineered for drone microphones operating in challenging aerial environments where propeller wash, high-velocity wind, and sudden rain showers threaten audio capture. The vent serves a dual purpose: it passively attenuates wind buffeting noise that can overwhelm the microphone element, and it provides a waterproof barrier against precipitation

Portable Bluetooth Speaker EPTFE IP67 Waterproof Acoustic Vent Cover Product Overview This EPTFE IP67 waterproof acoustic vent cover is designed for portable Bluetooth speakers that must deliver room-filling sound despite exposure to pool water, beach sand, and outdoor grime. The vent cover is a pre-shaped, multilayer assembly consisting of an EPTFE film bonded to a black non-woven support, offering a combination of high water resistance and low acoustic loss. It is

Medical Grade EPTFE Miniature Acoustic Vent For Hearing Aid Devices Product Overview This medical-grade EPTFE miniature acoustic vent is purpose-designed for hearing aid devices, where acoustic transparency, biocompatibility, and long-term resistance to cerumen (earwax) and moisture are non-negotiable. Hearing aids operate in the warm, humid, and oily environment of the ear canal, making them uniquely vulnerable to contamination. The vent membrane is fabricated from USP Class

EPTFE TWS Earbud Acoustic Vent For Air Pressure Balance And Protection Product Overview This EPTFE acoustic vent is optimized for True Wireless Stereo (TWS) earbuds, addressing the dual requirements of driver back-volume pressure equalization and environmental protection. When a TWS earbud is inserted into the ear canal, a sealed volume of air is trapped, which can cause the speaker diaphragm to deflect and distort, especially during insertion or when ANC (Active Noise
