Abstract
An image capture device includes a housing that includes a pattern of apertures and a microphone disposed within the housing and proximate to the apertures. The image capture device includes a membrane assembly. The membrane assembly includes a support disposed between the housing and the microphone and a channel defined in the support that directs sound waves from only one of the apertures in the pattern to the microphone. The membrane assembly further includes a membrane that extends across the channel and separates the one of the apertures and the microphone.
Claims22
An image capture device, comprising:
- a housing that includes a pattern of apertures;
- a microphone disposed within the housing and proximate to the pattern of apertures;
- and
- a membrane assembly, comprising:
- a support disposed between the housing and the microphone, wherein the support comprises:
- a first layer adjacent to the microphone;
- and
- a second layer in direct contact with the housing and defining a pattern of indents that are aligned with a portion of the pattern of apertures of the housing;
- a channel defined in the support and configured to direct sound waves from only one of the apertures in the pattern of apertures to the microphone;
- and
- a membrane that extends across the channel and separates the one of the apertures and the microphone,
- wherein the channel includes an external portion defined within the second layer and an internal portion defined within the first layer, and
- wherein the membrane separates the external and the internal portions of the channel.
(canceled)
A membrane assembly, comprising:
- a front layer in contact with an internal surface of a housing of an image capture device and defining an outer channel, the housing defining a pattern of apertures, and the front layer comprising indents that are configured to align with the apertures and that do not facilitate movement of sound to the microphone;
- a back layer in contact with a microphone assembly disposed within the housing and defining an inner channel aligned with the outer channel, the back layer configured to secure the membrane assembly against an internal component of the housing;
- and
- a membrane that separates the inner channel and the outer channel,
- wherein the inner channel, the outer channel, and one of the apertures in the pattern of apertures are aligned so that sound is facilitated to the microphone through the one of the apertures aligned with the inner channel and the outer channel.
(canceled)
An image capture device, comprising:
- a body including apertures;
- a microphone disposed within the body;
- and
- a membrane assembly separating the apertures and the microphone, the membrane assembly comprising:
- an inner layer adjacent to the microphone;
- an outer layer in contact with the body and defining indents that are aligned with most of the apertures of the body, the inner and the outer layer defining a channel that extends between one of the apertures that is not aligned with one of the indents and the microphone;
- and
- a membrane that separates the inner layer and the outer layer and bisects the channel so that sound is movable along the channel and moisture is prevented from traveling between the one of the apertures and the microphone.
