    SST-POROUS® Acoustic Vents

    SST-POROUS® Acoustic Vents protect speakers and microphones without blocking sound. The ePTFE membrane lets acoustic energy pass while keeping out dust, splash, and immersion contaminants.

    Key Features

    • Clear audio: Low insertion loss for voice and media playback
    • Particle and liquid protection: Options from splash/dust to immersion ratings
    • Compact integration: Thin, customizable parts for tight acoustic ports
    • Stable performance: Consistent sound after environmental exposure

    Typical Applications

    • Smartphones and feature phones
    • Smartwatches and wearables
    • Earbuds, headsets, and microphones
    • Two-way radios
    • Action cameras
    • Industrial handheld devices

    SST Acoustic Vents deliver a proven balance of high acoustic transparency and robust protection, helping device makers meet the demands of waterproofing, reliability, and user experience in today’s competitive consumer electronics market. Fully customizable solutions are available for mobile phones, wearables, walkie-talkies, scanners, and other portable devices.

     

    Typical equipment that requires protection

    Technical requirements
    Acoustic vents for clear sound transmission while providing waterproof and dustproof protection - Spider.

    Smart phone waterproof acoustic permeable (breathable) membrane

    Protection level: IPX7, IPX8 (waterproof Depth ≤2.5 meters)

    Microphone protection (sound transmission): Maintains excellent sound transmission and has excellent waterproof effect

    Ventilation (breathable): Meets IPX7, IPX8 protection levels while maintaining excellent breathability 
    Acoustic vents for clear sound transmission while providing waterproof and dustproof protection - Spider.

    Smart watch waterproof acoustic permeable (breathable) membrane

    Protection level: IPX7, IPX8 (waterproof depth ≤50 meters, 5ATM)

    Microphone protection (sound transmission): The acoustic hole needs to maintain a high waterproof effect, and at the same time, it is not allowed to significantly change the acoustic quality

    Vent (breathable): The vents need to ensure high water pressure resistance and have a certain breathability effect

    Includes our proprietary Spider Membrane to protect your electronic device from water-based and low surface tension fluids.

    Easy & Quick Installation

    Install quickly and easily on an enclosure’s interior or exterior, using manual or automated processes.
    Portable Electronics

    Main Applications:

    • Smartphones, TWS Earphones and Wearables (MEMS Microphone Protection)
    • Walkie-Talkies and Industrial Communication Devices
    • Security Cameras with Audio Functions
    • Smart Home Voice-Control Devices
    • Intelligent Electric Bicycle Audio Modules
    • Portable Scanners and Recording Equipment

    Challenges & Solutions Portable and outdoor acoustic devices are constantly exposed to water splash, dust, humidity, and pressure differentials caused by temperature changes. These conditions often lead to microphone/speaker failure, sound distortion, condensation, and shortened product lifespan.

    Spider Acoustic Vent adopts a specialized high-performance ePTFE microporous membrane optimized for sound transmission. It delivers reliable IP67/IP68 waterproof and dustproof protection, rapid pressure equalization, and minimal sound loss (low SNR degradation). Supports adhesive and other mounting methods to simplify design, enhance reliability, and extend service life. Fully customizable in size, acoustic performance, and protection levels.

    Acoustic vents for portable electronics by Spider, providing clear sound transmission while protecting internal components.

    Main Applications:

    • TWS Earbuds and Bluetooth Headsets
    • Smartphones and Tablets (Microphone Protection)
    • Smart Watches and Other Wearables
    • Smart Speakers and Voice Assistants
    • True Wireless Audio Products

    Challenges & Solutions Compact consumer audio devices must withstand daily exposure to sweat, rain, dust, and pressure variations while maintaining clear voice pickup and playback. Traditional sealing methods often compromise either acoustic performance or protection.

    Spider Acoustic Vent utilizes premium acoustic-grade ePTFE microporous membrane. It provides excellent waterproof and dustproof protection with negligible impact on sound clarity and effectively balances internal pressure to protect diaphragms. Enables thinner, more reliable designs and easily meets stringent IP rating requirements, making it the ideal solution for modern wearables and smart audio products.
