Abstract
An image capture device with a housing, a drainage microphone, processor, and drainage channel. The housing defining an audio depression. The drainage microphone coupled to the housing at a location of the audio depression and configured to capture audio. The processor coupled with a memory storing instructions that when executed cause the processor to apply a set of tuned beamforming parameters to the captured audio. The drainage channel within the housing to drain moisture from the drainage microphone. The drainage channel defining a channel entrance having a channel entrance width and a channel entrance height.
Claims20
An image capture device, comprising:
- a housing comprising an audio depression disposed on the housing;
- a drainage microphone coupled to the housing at the audio depression and configured to capture audio;
- a cover extending over the audio depression;
- a drainage channel formed between the audio depression and the cover with the drainage channel comprising:
- a channel entrance on a first side of the cover that allows liquids to flow between the audio depression and the cover;
- and
- a channel exit on a second side of the cover that allows the liquid to exit from between the audio depression and the cover;
- and
- a second microphone located on a second side of the housing relative to the drainage microphone,
- wherein the channel entrance has a width that is at least five times a height of the channel entrance.
An image capture device, comprising:
- a housing comprising:
- an audio depression forming a recess within the housing;
- a cover extending over the audio depression;
- and
- a drainage channel that extends between the audio depression of the housing and the cover, wherein the drainage channel extends between a channel entrance located along a top of the cover and a channel exit located along a bottom of the cover;
- a drainage microphone located within the audio depression, the drainage microphone configured to capture audio;
- and
- a processor coupled with a memory storing instructions that when executed cause the processor to apply a set of tuned beamforming parameters to the captured audio,
- wherein a channel entrance width of the channel entrance is greater than 4 mm.
An image capture device comprising:
- a housing defining an audio depression positioned on a first surface of the housing;
- a drainage microphone coupled to the housing at a location of the audio depression, the drainage microphone configured to capture audio;
- a second microphone disposed on a second surface of the housing, wherein the second surface is toby the first surface and is configured to capture the audio;
- a processor coupled with a memory storing instructions that when executed cause the processor to:
- receive the captured audio from the drainage microphone, the second microphone, or both;
- and
- process the captured audio;
- and
- a drainage channel defined in the housing to drain moisture from the audio depression, the drainage channel comprising:
- a channel entrance having a channel entrance width and a channel entrance height, and
- a channel exit having a channel exit width and a channel exit height,
- wherein the channel entrance has a width that is at least five times a height of the channel entrance, and
- wherein a channel entrance width of the channel entrance is greater than 4 mm.
