High Quality And Reliable Acoustic Vents Enables Immersion Down to 30m For Portable Electronic Devices


The all new acoustic vent from Gore delivers high-quality acoustics and reliable ingress protection. It enables sound quality even after the smartphones or other portable electronics devices is immersed in 30 meters of water for 10 minutes.

Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact and water by mechanical casings and electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof. As mentioned in the release, the new Gore GAW331 complies with standards relevant to smartphone applications, such as IEC 60529 for IP. Under this standard, the GAW331 qualifies for both the IP67 rating (temporary immersion in 1 meter of water for 30 minutes) and IP68 rating (continuous immersion in 10 meters of water for 60 minutes and 30 meter submersion for 10 minutes).

According to the press release, “The GAW331 delivers reliable protection and immersion performance, as measured by the most rigorous industry standards. It complies with ISO 22810, the standard that defines water resistance for watches, meaning the GAW331 vents withstand immersion at 30 meters for 10 minutes without leaking. It uses a unique oleophobic ePTFE (expanded polytetrafluoroethylene) membrane to deliver high performance in very small electronic devices with a typical part thickness of just 0.28 mm. It has been engineered to deliver a typical airflow of 285 ml/min/cm2 (dp = 70 mbar). This provides the optimal balance of two critical and competing performance requirements i.e. a highly-protected housing that meets ISO and IEC standards and a highly-breathable housing that reduces transducer bias and delivers high-quality acoustics.”

Gore’s Sara Ellis, who partnered with fellow Product Specialist Shigeharu Murayama to lead the development of this new vent for immersion applications said, “Today’s consumers expect reliable performance from their portable electronic devices, whether they are snorkeling with their action camera or swimming with their smartwatch.”

The GAW331 is available in a standard product size of 1.6mm inner diameter x 4.2mm outer diameter.
