Overview:
Today's portable electronic devices need to stand up to dust and splash hazards that go way beyond commonly used IP standards.
In audio devices with braided exhaust materials, metal particles can be sucked into and attached to speaker magnets. As these particles accumulate, their increasing mass and weight inhibit the diaphragm from producing high levels of sound pressure.
Microvent® Acoustic Vents for Dust and Splash using non-woven film material, with three-dimensional tortuous path structure. This allows them to effectively capture particles of different shapes and sizes while preventing acoustic degradation and improving speaker life and equipment reliability, also providing reliable dust and splash protection with uncompromising sound quality.
Applications for Dust and Splash Protection Acoustic vents:
Ideal for portable electronic devices that need to stand up to dust and splash hazards that require good sound transparency and acoustic performance–rated up to IP6x:
Smartphones and Feature Phones
Digital action and SLR Cameras
Smart Speakers and Home Devices
Microphones,Earphones and Headsets
Two-way Radios
