An electronic device has an acoustic transducer with an acoustic diaphragm. The diaphragm has opposed first and second major surfaces. A front volume is positioned adjacent the first major surface. A back volume is positioned adjacent the second major surface. An elongated channel defines a barometric vent and extends from a first end fluidly coupled with the front volume to a second end fluidly coupled with the back volume, fluidly coupling the front volume with the back volume. The elongated channel may have a high aspect ratio (L/D), providing the vent with a substantial air mass. The elongated channel may be segmented to define a higher-order filter. For example, a segmented channel can have a cascade of repeating acoustic-mass and acoustic-compliance units, providing the barometric vent with additional degrees-of-freedom for tuning.

The present disclosure relates to microphone devices. One microphone assembly includes a transducer and a housing. The microphone assembly includes an integrated circuit coupled to the transducer. The housing includes a port, a base, and a cover. The cover includes an inner wall and an outer wall. The inner wall and outer wall can be coupled to the base. The inner wall and the base are mechanically coupled and define an enclosed volume. The transducer is disposed in the enclosed volume.
