Overview:
Consumer electronics need to be vented in a variety of situations, such as skiing, air freight, or other similar situations to withstand sudden changes in temperature or height. In most cases, the enclosures of electronic devices are very fragile. Internal pressure changes in the daily environment may easily cause seal failure or component contamination, leading to the failure of electronic equipment. Therefore, timely release of pressure is every electronic developers and designers need to face the problem.
Microvent® Acoustic Vents for immersion applications facilitate transmission of sound with superior acoustics performance, deeper immersion protection and enhanced contamination resistance. Microvent® can tailor this material around the desired functionality to repel water, sweat, cleaning solutions and low surface tension liquids like detergent and oils without sacrificing acoustic performance.
Microvent® enable the ventilation of enclosures and containers, balance pressure differences and maintain perfect sound quality.
Microvent® Acoustic Vents are subjected to rigorous Extended Water Entry Pressure (eWEP) testing for deeper immersion protection. Smartphones can be protected from water as deep as 5 meters for as long as 30 minutes and wearables as deep as 50 meters for 10 minutes which is superior to the competition and decreases the number of defective products produced.
Applications for Immersion Protection Acoustic vents:
Ideal for portable electronic devices exposed to water challenges, including immersion, that require good sound transparency and acoustic performance.
