Abstract

An audio device includes an enclosure, an acoustic transducer, and a semi-permeable membrane assembly. The enclosure defines a sealed internal volume and has an exterior opening. The acoustic transducer is secured to the enclosure and includes a magnetic motor assembly with a motor vent. A ventilation structure is defined between the motor vent and the exterior opening to establish gas communication with an ambient environment. The semi-permeable membrane assembly is positioned at a gas outlet of the ventilation structure. Optionally, an extension tube is provided to connect the motor vent to the exterior opening. The semi-permeable membrane assembly permits controlled gas exchange for pressure equalization while blocking ingress of liquid and contaminants.
