Why Electronics Fail
The trend toward smaller devices that can function in any kind of environment increases the demand for more durable protection, and today’s smaller designs mean space is at a premium. Portable electronic devices need openings so sound can enter and exit their speakers, receivers, and microphones. This unique design requirement can lead to many potential sources for electronic failure. Many types of acoustic vents are available in today’s market, and if you select the wrong vent to protect your acoustic transducers, it can easily compromise performance or damage your electronic device — ultimately leading to customer dissatisfaction.
Open Audio Ports
If audio ports are not covered with protective barriers, they expose the sensitive electronics inside the housing to potential damage from the external environment — water, dust, dirt and other contaminants — but covering them can compromise sound quality.
GORE® Acoustic Vents are engineered to preserve sound quality and prevent distortion, attenuation, and reduced frequency response. At the same time, they create a protective barrier that prevents contaminants from entering through the port.
The electronics of a device generate heat as they operate, which increases the internal temperature, leading to a pressure buildup inside the housing. If your product is exposed to a sudden decrease in environmental temperature, the internal pressure suddenly drops. This pressure change puts significant stress on the housing seals. Over time, cycling between high and low pressure can compromise the seals, which in turn allows water and contaminants to enter the device and ultimately causes it to fail.
The unique materials used in GORE® Pressure Vents allow air to flow freely through the vent, enabling pressure to dissipate safely from devices and preventing seals from failing.
