Improving mobile phone acoustics

W L Gore & Associates announces the launch of the GORE Acoustic Vent GAW333 – a smaller, smarter way to improve mobile phone acoustics while maintaining IPX8 immersion protection and IP6X particle protection.

With an inner diameter as small as 1.5 mm, the new GAW333 offers greater design flexibility to mobile phone developers.

GAW333 delivers robust sound performance, with the lowest acoustic attenuation of any IPX8 GORE Acoustic Vent. As measured with a MEMS microphone system, a GAW333 vent with an inner diameter of 1.8mm exhibits very low transmission loss: typically around 2 dB at 1kHz.

The advanced microporous structure of this GORE Membrane rapidly and reliably equalises pressure differentials, while remaining virtually impenetrable to water, dirt and debris. Capable of withstanding extended immersion (at 2 meters for 1 hour), new GAW333 achieves IPX8-level water protection, as well as IP6X particulate protection.

Available in standard sizes, this hydrophobic white acoustic vent incorporates a durable acrylic adhesive that maintains a secure, watertight bond to the component in temperatures ranging from -40 to 85 °C.
