Acoustic Protective Covers
 Mobile phones and other portable wireless devices are often used in severe environments, potentially exposing them to water and dust that can damage sensitive components. GORE™ Protective Covers are placed over ports in these devices to protect them from dust, splashes, and temporary water immersion, and to provide pressure venting and equalization.
GORE™ Protective Covers are used in acoustic applications to provide a barrier against water and dust contamination, without significantly compromising sound quality. They also resist a variety of common liquids such as soda and coffee.
Gore also offers solutions to protect open pressure-venting ports, without significantly limiting air exchange. These ports are necessary to regulate pressure fluctuations in the device due to temperature, altitude, and sound pressure variations and to release battery discharge gases.
GORE™ Protective Covers are available in custom shapes and sizes, and they include an integral pressure sensitive adhesive. The performance matrix below can be used as a guide in selecting the right material for your application.
