摘要
An image capture device includes an audio depression formed into the housing with a drainage microphone mounted therein. A cover protects the drainage microphone disposed beneath the cover from an environment external to the image capture device. The cover and audio depression define a drainage channel extending from a channel entrance, through a channel volume, and out a channel exit. The surface area of the opening of the channel entrance is proportioned relative to the channel volume such that the ratio of the surface area to volume is greater than ten percent. This allows the cover to shift resonance outside of a desired frequency band.
